An update to the CCDev2 milestones (http://www.nasa.gov/pdf/679671main_CCDev2_Public_August2012_508.pdf) has just been posted by NASA.  Only one remaining milestone for SNC, and that is the free-flight and landing tests of the Engineering Test Article (full size).  The chart shows completion of this milestone moved to the end of the 2012 from its previous time of around the end of July 2012.

In the video interview with Cheryl McPhillips posted above, she says drop tests will start in November.

The good news is that they have a workable schedule that can see the DC flying, maybe still in 2012.

Are the drop tests still on for November as it is anyways? Would love to see DreamChaser airborne Enterprise style this year.

Well, Mojave.  (It probably wasn't too different there last week.)

I would have been fine with July and August, because I could be there.  The closer it is to the holidays without being coincident, the less chance I have of making it back.

Here in muggy Minnesota (or Florida), I'd agree with you. In a desert? It's pretty nice.

Update from NASA Commercial Crew Program.  Looks like the first free-flight test has slipped from November into next year [my bold]:

NASA’s CCiCap Partners Off To A Fast Start
Commercial Spaceflight 60-day Report Issue 9 - October 18, 2012
...
Sierra Nevada Corporation (SNC) is making significant progress on its Engineering Test Article (ETA). "SNC is working very hard to complete the build of our ETA to support free flight testing in the first quarter of next year, currently installing landing gear, flight controls, brakes, hydraulics, and extensive instrumentation,” said Steve Lindsey, director of Flight Operations at SNC. “All of the ETA's avionics are currently undergoing box to box bench testing, and the latest complete flight software version is now running successfully on the flight control computer. The flight control actuators and actuator controls are in final qualification testing and will be installed into our flight control integration lab within the next 2 weeks. Mission Control Center display development is in work, along with extensive flight test and integrated test planning.” The ETA will perform flight tests for both CCDev2 and CCiCap milestones. SNC also completed its first CCiCap milestone in mid August—a two-day program implementation review that established its management plans for executing the CCiCap SAA. In preparation for SNC’s next milestone in October, an integrated system baseline review, it has produced and released design documentation for the NASA partner integration team to review.

2012 Innovation Expo: Sierra Nevada Corporation

Published on Oct 29, 2012 by NASAKennedy

Merri Sanchez with Sierra Nevada Corporation (SNC) talks to Kennedy Space Center employees about the company's Dream Chaser spacecraft and its partnership with NASA's Commercial Crew Program to develop America's next-generation crew transportation.

The 2012 Kennedy Space Center Innovation Expo on Sept. 6 was a centerwide event that brought in inspirational speakers from outside companies, gave researchers a chance to show off some of their work and employees the opportunity to see facilities they hadn't viewed before.

The overall goal of the event was to highlight employee innovation and collaboration in everyday work that will help shape the future of Kennedy and the agency.

An article in their local newspaper (http://www.dailycamera.com/louisville-news/ci_21936366/sierra-nevada-aims-give-dream-chaser-its-own?IADID=Search-www.dailycamera.com-www.dailycamera.com) talking about Sierra Nevada getting a new building dedicated to Dreamchaser.  It says that they have hired 30 people and will hire another 80.

Some people think SNC "lost" the CCiCap competition by getting the smallest of the awards but I don't think they could use more money productively.  This looks like a very rapid ramp-up as it is.

That's a bit harsh, but it's true they were less favored in the awards. However they certainly seem to going ahead at full speed and seem pretty confident.

You have to ask could they really  have a shot at delivering a vehicle at this level of funding?

LockMart definitely knows what the heck they're doing. Very good choice.

Dreamchaser's stock went up in my book.

I don't know. SNC had Boeing as a subcontractor previously for DC. If SNC is only switching subcontractors from Boeing to LM, I am not sure if this is good news.

It would be interesting to know more about this deal. It seems that the deal is only for LM being a subcontractor in DC. If I understand the deal correctly, LM is not investing anything in DC. I imagine that this also means that Boeing is out as a DC subcontractor. I can't imagine both LM and Boeing being involved as subcontractors in DC.

After listening to the audio on L2, LM is indeed a subcontractor for SNC (not an investor). But it seems like they will be an important subcontractor. So it is a big deal in that sense.

There is supposed to be a press release that will give more details on the LM-SNC partnership.

Boeing Phantomworks certainly used to be listed by SNCSpace as on their team for composite structures (they cited Boeings Bird of Prey IIRC). But I'm not sure they've actually built anything for SNC yet. Anyone know differently?

As Boeing gets further into their CST-100 work I could see how their involvement with a competitors team might not sit well with everyone.

Not really anything that wasn't covered, but here it is for good measure:

Sierra Nevada Corporation and Lockheed Martin Space Systems Company Partner On Dream Chaser Programs (http://www.sncorp.com/press_more_info.php?id=530)

SPARKS, Nev., – January 30, 2013 – Sierra Nevada Corporation’s (SNC) Space Systems is pleased to announce Lockheed Martin Space Systems Company of Littleton, Colo., is joining the SNC Dream Chaser® team.  Lockheed Martin will be an exclusive partner to SNC on NASA's Certification Products Contract (CPC) and has been competitively selected to build the composite structure for the Dream Chaser at NASA’s Michoud Assembly Facility in New Orleans, La.  SNC was awarded $10 million for CPC Phase 1 to work with NASA towards government certification of the SNC Dream Chaser orbital crew transportation system.

"The SNC team is thrilled that Lockheed Martin will be joining our expanding world-class team of partner organizations also working to certify the Dream Chaser Space System for crewed flights to the International Space Station for NASA.”  said Mark Sirangelo, corporate vice president and head of SNC’s Space Systems. “The CPC contract offers the Dream Chaser team the opportunity for a more robust technical interchange with NASA as we work to develop a safe, reliable orbital crew transportation system.  This contract capitalizes on SNC's success working with NASA's Commercial Crew Program, as well as Lockheed Martin's expertise in developing and certifying Orion's beyond low Earth orbit human spaceflight hardware as part of NASA's Exploration Program.  Our team will work towards the common goal of certifying the Dream Chaser to provide the next generation human transportation system."

Lockheed Martin is developing NASA's Orion Multi-Purpose Crew Vehicle (MPCV) and brings extensive and current experience in obtaining NASA certification for a crewed flight vehicle to the Dream Chaser program.

“We are pleased to join the SNC Dream Chaser team. Lockheed Martin brings with it tremendous human-rated space flight knowledge from our significant experience with large, human-flight structures, including 135 flights with the Space Shuttle’s external fuel tanks.  We feel we can share many synergies between the Orion exploration spacecraft and the Dream Chaser lifting body space vehicle. This provides a great opportunity to take NASA’s investments in crew exploration capabilities and leverage them toward commercial transportation to low Earth orbit,” said Jim Crocker, vice president and general manager, Civil Space, Lockheed Martin Space Systems Company.

The composite structure for the Dream Chaser flight test vehicle is being built under the SNC $212.5 million Space Act Agreement for the NASA Commercial Crew Integrated Capability Program. This effort leverages the extensive Lockheed Martin experience in building composite structures for spacecraft and high performance aircraft.   With the addition of Lockheed Martin as a partner on the Dream Chaser program, SNC is now working with partner organizations in over 15 states on NASA's Commercial Crew Integrated Capability program.

 “We are pleased to include Lockheed Martin as part of the Dream Chaser Team to develop early certification products and to build critical flight hardware.  Their recent human spacecraft certification experience and composite expertise make them a great addition to our program,” said Jim Voss, vice president of Space Exploration Systems and Dream Chaser program manager.

The SNC and Lockheed Martin partnership represents the best of entrepreneurial spirit and established space mission success, collaborating on vehicle development, certification and reaching additional customer markets for the Dream Chaser orbital vehicle.  The team looks forward to working with NASA to successfully execute on the first round of the CPC contract and move towards offering the Dream Chaser Space System as a commercial solution to crew and cargo servicing of the International Space Station.

That's a little bit unfair. Even if we set aside the fact that the X-33 tank problems were far more than a decade ago, and word on the street is such tanks can be made now, LM aren't being asked to build cryogenic-temp, pressurized structures here.

I'm curious to see if this relationship remains as narrow in scope. For all SNCs capabilities, LM have a lot of relevant experience they could benefit from, e.g. building crewed vehicles.

Let's just hope Congress/NASA funds Dream Chase, CST-100, Dragon throw their test flights and does not down select to just one. Having the three would ensure the U.S. ability to send crew to orbit whether for ISS, other, or future space stations ( gov. or private ).

So with Lockheed Martin now in the commercial crew works is this a positive sign for a future commercial business?

Thanks for remembering the workers effected by the politics of this. The  hourly work force in 2006 was a little over 800 people at Michoud. Today we are at 22 people working on the Orion project and commercial TPS.

It looks like Bigelow might offer their space station again with Dragon and CST-100 as the crew taxi's.

Even if this does not happen again it will be important that Congress/NASA sees that we get at least two suppliers for crew sooner than later. There are other options for the LEO crew taxi's besides ISS and commercial space stations.

Because I work at Michoud and there was no mention of KSC in the article.
I also worked at KSC and MSFC  on TAD assignments. I am well aware of what happen at KSC and Brevard county. I was at KSC when they were doing the end of the program events in the VAB. We had a great  relationship with the USA guys and we would all hang out when we where in town. The majority of people that finished up the program were working under the WARN act but we all gave it 100 percent till the end.
I only know the Shuttle program at KSC and think what a great set up it was. A true space port in my opinion. I am bitter about the the loss of this also. Any way I have met many people  there that lived in the Orlando area.
I think the Orlando metro area should be included in your figures. But i dont want to debate this. It really doesn't matter.
I do feel for the KSC guys loss also, very deeply as a matter of fact.
And I do  keep up with Brevard county news, (Florida Today).
The last kick in the gut was seeinga picture  the USA sign being removed at the Port Canaveral offices.

Doubt that DC uses fuel cells. Even if it did, it would have to carry a lot of reactants to keep it powered for 6 months. Anyway, that's totally unnecessary because DC, like CST-100 would draw its power from ISS while docked.

DC is battery only and then ISS connected for power.  However they have said that the vehicle could be modified to have solar power for long duration free fllights if necessary.  Remember, SNC makes deployable solar systems for other missions.

That begs the question if the other missions SNC have suggestrf DC for would be classed as "standard" or "extended" and hence need an array.

For extended missions, the Langley folks considered a "towed package" housed in the fairing. This was for the larger HL-42 variant, but if it were practical, could presumably be scaled down for the DC.

See "towed packed" in the following:
http://www.astronautix.com/craft/hl42.htm

Others have pointed out that this could shift the center of mass way aft and alter the vehicle's controllability, perhaps to the point of overwhelming what the stock RCS can handle. There is also the fact that the hybrid/OMS motors will fire right next to - or onto! - your payload, but this doesn't seemed to have concerned the HL-42 team.

One dubious solution would be to mount the payload on a two-part support structure that splits into two two halves and swings around above (and below) the vehicle resulting in a center of mass close to a normal DC. You'd have to worry about clearing the rudder.

This adds mass (bad) but has the advantage of moving the payload away from the hybrid motors and RCS nozzles, revealing the docking port, and if an EVA were to occur from the top-hatch, placing the payload nearby.

Of course if we're just talking about solar arrays, that's a simpler matter as they could be light enough to not complicate vehicle handling. They could be folded in the space behind the docking adapter, and deploy up and down (right after Centaur sep, before the hybrids light?)

The payload module could have its own RCS controlled from the Dream Chaser.

Once in LEO the Dream Chaser could fly back and its pilot dock it to the back of the payload module allowing the whole assembly to be pushed.

The Dream Chaser's motors are at the back with the docking port.  So to perform a burn without destroying the cargo the cargo module has to be moved out of the way.

Placing the external tank on the side of the Shuttle is likely to have been done for a similar reason.

If you are going to anywhere other than the LEO orbit the launch vehicle left you in you are going to need a burn.

This conversation should be in the Discussion thread rather than the Update thread.

This morning I had the privilege of attending a presentation by Todd Mosher at SNC. The ETA is undergoing a lot of work in prep for shipment to Edwards, so we couldn't get a tour. They asked us to leave camera's/phone's in our cars so no pix, sorry.

Here is my run down of the presentation:
A lot of the presentation was, as expected, history of SNC, history of DC/HL-20 (including a mention of BOR-4), what is DC, and what is CCDev/CCiCap. There were many questions and I got a chance to corner Todd after the event to ask some more. I didn't take a notebook, so this is from my (poor) memory.

Someone asked how many they plan to build. His reply went from wildly optomistic to nominal. 2-4 for NASA/ISS CCiCap but if the market gets bigger with Bigelow, etc. and other countries wanting to send up their own astronauts for cheap, they could see selling many seats and building many DCs.

When asked, he wouldn't talk much about the green RCS. I was a little surprised there. He kinda waffled a bit, then started talking about the hybrid mains. Is that some kind of IP? He did talk a lot about the low-G re-entry and immediate access to science payloads returning from micro-G due to green prop.

LM is helping with structures and is manufacturing the composite core of the flight articles in Michoud as well as man-rating requirements and verification. Some systemsy stuff WRT man-rating and verification, but they are not being contracted as a Systems overseer/helper/savior or anything like that. Things are going well.

Heli-lift will not complete drop testing and they are looking into alternative higher altitude carry vehicles. Forgot to ask about self ferry. Said WK2 is a perfect fit, but that VG is focused on tourism and has plenty to do on their own. Didn't sound frustrated in any way but obviously seemed to indicate they would've very much liked to have gone that route.

Since some of the drop tests will be auto and an advertised capability is to auto land, I asked if they could do a full mission profile autonymously. He said it is possible for DC to do autodocking but that isn't developed. DC will be piloted for now but they hope to add that in the future. First orbital flight will be uncrewed but is a free-flyer with no ISS interaction.

When he said they could auto-dock, I asked if they had some kind of LIDAR for 3d awareness. He said they are in the process of down-selecting now.

Forgot to ask about pad abort or MaxQ abort tests or milestones. He said MaxQ for lifting body is much lower (~500) than capsule (~700), I'm guessing that is mph, and that the hybrids were PLENTY for MaxQ abort with these lower requirements.

They are currently using Boeing X-37 avionics and SW for autolanding but they aren't the flight avionics. He said a choice has been made WRT flight avionics (I want to sell him mine, but... he kinda grimaced when I said my company name, bummer!) and to expect an announcement, soon.

Tue, 26 Mar 2013 08:22:41 PM UTC

Sierra Nevada Corp. (SNC) Space Systems is putting the Engineering Test Article of its Dream Chaser through a Ground Resonance Test at the company's facilities. The testing is standard for aircraft and helicopters and confirms that vibrations from machinery inside the craft won't make it shake itself apart. Preparations for wind tunnel testing continue on track following a recent test readiness review with NASA's Commercial Crew Program (CCP). The testing, scheduled for later this month then in May and June, is tied to one of the milestones SNC will meet to reduce risk in spacecraft designs during the agency's Commercial Crew Integrated Capability (CCiCap) initiative. The Dream Chaser is being developed as a private spacecraft that can carry crews into low-Earth orbit and potentially the International Space Station by mid-decade.

Elements of Sierra Nevada Corp. Space Systems' Dream Chaser design will undergo significant testing this month, including evaluations of the Thermal Protection System in a phosphor thermography wind tunnel. The Thermal Protection System, or TPS, is the heat shield that keeps super-heated plasma from damaging the spacecraft as it enters Earth's atmosphere. The plasma is created by friction between the spacecraft, which is flying in at more than 17,000 mph, and the air in the upper reaches of the atmosphere. The heat shield for the Dream Chaser also challenges designers because it has to hug the aerodynamic form of the spacecraft that is designed to glide to a runway landing after returning from space.

Sierra Nevada Corporation Completes Dream Chaser® Milestones
for Commercial Crew Integrated Capabilities Program


SPARKS, Nev., – April 25, 2013 – Sierra Nevada Corporation’s (SNC) Space
Systems has successfully completed two milestones as part of NASA's Commercial Crew Integrated Capability (CCiCap) phase of the agency’s Commercial Crew Program.  SNC completed the Program Implementation Review, providing NASA with detailed plans for advancing the Dream Chaser® crew transportation system towards a critical design state. SNC also completed an Integrated System Baseline Review that communicated the post-Preliminary Design Review maturity of the baseline Dream Chaser® orbital crew vehicle, mission systems, ground systems, and United Launch Alliance's Atlas V launch vehicle.

“The successful completion of these milestones resulted in affirmation that the Dream Chaser® Space System design meets its mission requirements as we work towards rebuilding the United States’ capability to fly astronauts into low Earth orbit,” said Jim Voss, vice president of SNC's Space Exploration Systems. “Both CCiCap milestones offered us the opportunity to communicate SNC's detailed development plans, as well as to receive and incorporate NASA's comments and feedback.”

SNC was awarded $212.5 million by NASA in August 2012 and to date has received over $330 million by NASA’s Commercial Crew Program.  The funding represents the agency's co-investment in furthering the development of the Dream Chaser® Space System design to carry crew and critical cargo to and from the International Space Station. The Dream Chaser orbital crew vehicle is scheduled to complete its first free flight test in conjunction with NASA's Dryden Flight Research Center at Edwards Air Force Base in Calif., in 2013.

SNC Completes Dream Chaser Safety Review Milestone
http://www.nasa.gov/exploration/commercial/crew/snc-safetyreview.html

Quote
Sierra Nevada Corp. (SNC) Space Systems of Louisville, Colo., has completed its first major, comprehensive safety review of its Dream Chaser Space System. This is the company's latest paid-for-performance milestone with NASA's Commercial Crew Program (CCP), which is working with commercial space partners to develop capabilities to launch U.S. astronauts from American soil in the next few years.

The Integrated Systems Safety Analysis Review provided NASA with hazard reports and safety and reliability plans for the major components of the company's integrated crew transportation system, including the Dream Chaser spacecraft, United Launch Alliance Atlas V rocket, and flight and ground systems.

"Safety review milestones are critical to ensuring safety and reliability techniques and methods are incorporated into space systems design," said Ed Mango, NASA's CCP manager. "NASA's participation in these reviews provides our partners with critical design experiences from past human spaceflight activities."

SNC is developing its Dream Chaser Space System under NASA's Commercial Crew Integrated Capability (CCiCap) initiative, which is intended to lead to the availability of commercial human spaceflight services for government and commercial customers.

"Dream Chaser is making substantial progress toward flight with the help of our NASA team," said Mark Sirangelo, head of SNC's Space Systems. "The ability to openly exchange information through the work on these CCiCap milestones is invaluable for many reasons, such as communicating Dream Chaser development plans and receiving timely feedback from NASA, all of which help to improve our design and maximize safety and reliability. As we begin our flight test program we have a better and stronger program due to our partnership with NASA."

SNC Dream Chaser Testing Begins at NASA's Dryden, Langley
May 15, 2013

Sierra Nevada Corporation's (SNC) Space Systems Dream Chaser flight vehicle arrived at NASA's Dryden Flight Research Center in Edwards, Calif., Wednesday to begin tests of its flight and runway landing systems.

The tests are part of pre-negotiated, paid-for-performance milestones with NASA's Commercial Crew Program (CCP), which is facilitating U.S.-led companies' development of spacecraft and rockets that can launch from American soil. The overall goal of CCP is to achieve safe, reliable and cost-effective U.S. human access to and from the International Space Station and low-Earth orbit.

Tests at Dryden will include tow, captive-carry and free-flight tests of the Dream Chaser. A truck will tow the craft down a runway to validate performance of the nose strut, brakes and tires. The captive-carry flights will further examine the loads it will encounter during flight as it is carried by an Erickson Skycrane helicopter. The free flight later this year will test Dream Chaser's aerodynamics through landing.

Meanwhile, on the east coast, several NASA astronauts will be at the agency's Langley Research Center in Hampton, Va., this week to fly simulations of a Dream Chaser approach and landing to help evaluate the spacecraft's subsonic handling. The test will measure how well the spacecraft would handle in a number of different atmospheric conditions and assess its guidance and navigation performance.

"Unique public-private partnerships like the one between NASA and Sierra Nevada Corporation are creating an industry capable of building the next generation of rockets and spacecraft that will carry U.S. astronauts to the scientific proving ground of low-Earth orbit," said William Gerstenmaier, NASA's associate administrator for human exploration and operations in Washington. "NASA centers around the country paved the way for 50 years of American human spaceflight, and they're actively working with our partners to test innovative commercial space systems that will continue to ensure American leadership in exploration and discovery."

The Dream Chaser Space System is based on Langley's Horizontal Lander HL-20 lifting body design concept. The design builds on years of analysis and wind tunnel testing by Langley engineers during the 1980s and 1990s. Langley and SNC joined forces six years ago to update the HL-20 design in the Dream Chaser orbital crew vehicle. In those years SNC has worked to refine the spacecraft design. SNC will continue to test models in Langley wind tunnels. Langley researchers also helped develop a cockpit simulator at SNC's facility in Louisville, Colo., and the flight simulations being assessed at the center.

By the way, this is not how I'd transport the orbital spacecraft across the country.  I'd build it a non-descript "crate" (like an ISO container, but wider), put it inside, and take that by truck.

While NASA works with U.S. industry partners to develop commercial spaceflight capabilities, the agency also is developing the Orion spacecraft and the Space Launch System (SLS), a crew capsule and heavy-lift rocket to provide an entirely new capability for human exploration. Designed to be flexible for launching spacecraft for crew and cargo missions, SLS and Orion will expand human presence beyond low-Earth orbit and enable new missions of exploration in the solar system.

Astronauts to Test Dream Chaser Flight Simulator at NASA Langley
MEDIA ADVISORY : 13-019   May 15, 2013

HAMPTON, Va. -- A group of NASA astronauts will be at NASA's Langley Research Center this week to fly in a simulator that is being used to help evaluate the subsonic handling characteristics of Sierra Nevada Corporation (SNC) Space Systems' Dream Chaser spacecraft.

The simulation is of an approach to -- and landing at -- Edwards Air Force Base in California -- the final 10,000 feet (3,048 meters) and 60 seconds of a future Dream Chaser flight. The astronauts will evaluate how well the spacecraft would handle in a number of different atmospheric conditions as well as assess its guidance and navigation performance.

NASA Langley developed the flight control laws that are being used in its motion-based Research Flight Deck simulator, while Draper Laboratory engineers in Houston, Texas, and Cambridge, Mass., developed the guidance and navigation system software.

Reporters are invited to observe a simulation on Thursday, May 16, at 2 p.m. Please RSVP to Sasha Congiu by noon on Thursday, May 16, at 757-864-5473/272-9859 or by e-mail to [email protected]

The Dream Chaser is based on Langley's Horizontal Lander (HL-20) lifting body vehicle design. HL-20 was a successor to the earlier HL-10 lifting body reentry vehicle concept developed by Langley during the 1960s, but was influenced by a Soviet era space plane design. Langley engineers had devised a development plan for the HL-20 in the 1980s and 90s, creating pilot landing scenarios in simulators, testing designs in wind tunnels and even building a full-scale model -- with the help of universities -- to study crew challenges.

The control laws being used in the current simulation were refined for the HL-20, but Langley engineers say they date back to research done during the development of the Space Shuttle in the 1970s.

SNC is developing its Dream Chaser Space System under NASA's Commercial Crew Integrated Capability (CCiCap) initiative, which is intended to lead to the availability of commercial human spaceflight services for government and commercial customers.

NASA Langley has collaborated with SNC in the design and development of the Dream Chaser Space System for six years

Thanks for the vid cap! :)  Nice display but at less than 10,000 ft. you’re not going to spend too much time staring at the panel with such a high sink rate. Makes for a good quick scan and lower field of vision. I like the color change when control surfaces are activated which cuts down having to stare and process the data in your mind...

SNC's Dream Chaser Arrives at NASA Dryden for Tests

Published on May 17, 2013
Sierra Nevada Corporation Space Systems' Dream Chaser engineering flight test vehicle, arrived at NASA's Dryden Flight Research Center in Edwards, Calif., May 15, 2013 to begin tests of its flight and runway landing systems. Wrapped in plastic with its wings and tail structure removed, the Dream Chaser test article was transported overland from the company's facility in Louisville, Colo.
Tests at Dryden during the summer of 2013 involve tow, captive-carry and free-flight tests of the Dream Chaser, which is based on the HL-20 lifting body design developed and tested at NASA's Langley Research Center.
The tests are part of pre-negotiated, paid-for-performance milestones with NASA's Commercial Crew Program (CCP), which is facilitating domestic companies' development of spacecraft and rockets that can launch from American soil into low-Earth orbit to transport crew and cargo to and from the international Space Station and perform other research missions.

Here is a screen capture from the video.  It appears that the simulator is a generic aircraft so i guess the windows might not be DC viewing.  The flat panel in the lower left shows a dynamic set of wings/rudder movement (?) so the pilots can understand there inputs? - in any case way cool.
Thanks for the vid cap! :)  Nice display but at less than 10,000 ft. you’re not going to spend too much time staring at the panel with such a high sink rate. Makes for a good quick scan and lower field of vision. I like the color change when control surfaces are activated which cuts down having to stare and process the data in your mind...

I was thinking that the simulator looked a lot like a 757/767 sim. I thought there were pictures of Charles Bolden and some Sierra Nevada executives trying out a sim that looked just like the interior of Dreamchaser.
Yup, you’re right SNC has it, but not three axis motion as is the NASA sim. Maybe LeeJay has seen it. ;)

I saw the simulator in Louisville.  It was a cockpit surrounded by about 5 large flat screen monitors (50" or so).  I didn't get to get inside but I watched as others flew it.

SNC's Dream Chaser is Unwrapped for Testing
Tue, 21 May 2013 9:45:28 PM UTC

Several Sierra Nevada Corporation employees recently unwrapped the Dream Chaser flight test vehicle following its five-state journey from Colorado to NASA's Dryden Flight Research Center in southern California. The prototype space access vehicle will undergo ground and approach-and-landing flight tests in the coming months at Dryden as part of NASA's Commercial Crew Program (CCP) development work. SNC is one of three companies working with CCP during the agency's Commercial Crew Integrated Capability (CCiCap) initiative, which is intended to lead to the availability of commercial human spaceflight services for government and commercial customers.

That's what I presumed. I suppose the more accurate question would be "are those 6 holes representative of where the RCS would be?" I'd assume that would be a high-heat area on re-entry where those holes in the thermal protection are.

Same as some Shuttle RCS nozzles.  The nozzles can handle the heat of combustion and the heat of reentry.

NASA Administrator Flies Dream Chaser Simulator

Published on May 24, 2013
NASA Administrator Charlie Bolden had the opportunity to fly a simulated landing of the Sierra Nevada Corporation (SNC) Dream Chaser while touring the agency's Dryden Flight Research Center in California on May 22.

SNC's Dream Chaser flight test vehicle arrived at Dryden on May 15 in preparation for tow, captive-carry and free-flight tests later this year. The testing is part of NASA's Commercial Crew Program (CCP) initiatives to develop safe, reliable and cost-effective access to and from low-Earth orbit destinations, including the International Space Station.

An Inside Look at SNC's Dream Chaser

Published on May 28, 2013
Cheryl McPhillips, the NASA Commercial Crew Program partner manager for Sierra Nevada Corporation (SNC), discusses the uniqueness of the company's Dream Chaser spacecraft and the milestones SNC plans to meet during the agency's Commercial Crew Integrated Capability (CCiCap) initiative.

http://www.youtube.com/watch?v=DheVO2qwzsI

McPhillips says that SNC is trying to get to CDR during the CCiCap period. That's news to me. NASA isn't paying them to get to CDR which means that SNC would have to fund the difference.
Title: Re: SNC Dream Chaser UPDATE Thread
Post by: Lurker Steve on 05/29/2013 01:39 PM
But since the competition will be at the CDR level after CCiCap is complete, SNC needs the Dream Chaser program at the same level.

Sierra Nevada Corporation Begins Dream Chaser®
Main Hybrid Rocket Motor Testing

Sparks, NV – June 6, 2013 – Sierra Nevada Corporation (SNC) announces the successful start of the latest phase of hybrid rocket motor qualification testing for the Dream Chaser® flight vehicle. SNC completed two tests this week at its rocket test facility in San Diego, Calif. A motor firing and ignition test was completed in preparation for upcoming motor tests under the current Commercial Crew Integrated Capability (CCiCap) award. SNC will conduct another series of hybrid motor firings to meet the next CCiCap contracted milestone beginning this summer.

After required modifications were completed, the test firing was conducted in order to validate Dream Chaser’s motor test stand. This was after required modifications were completed and to ensure that SNC can move forward with the future heavy weight motor test series with minimal test stand risk. The Dream Chaser version of the hybrid rocket motor was last tested in 2010 under the Commercial Crew Development Program (CCDev1) Space Act Agreement during which SNC completed three successful test firings of a single hybrid motor in one day.

In addition to manufacturing these motors for Dream Chaser, SNC also manufactures the hybrid motors for Virgin Galactic’s SpaceShipTwo vehicle which has undergone test firings on dozens of hybrid motors over the last two years. As announced in the SNC news release (April 29, 2013), SpaceShipTwo successfully completed its first powered flight test using SNC’s hybrid motor to power the vehicle to an altitude of 55,000 feet and reaching Mach 1.2.

“We are eager to begin the next series of motor testing for Dream Chaser,” said Mark Sirangelo corporate vice president and head of SNC’s Space Systems. “With the successful qualification this week in San Diego and the success of the powered flight of SpaceShipTwo, we are even more confident that our hybrid motor technology is the safest and most reliable system for human transportation.”

SNC’s hybrid rocket systems offer a safe, high performing, and non-toxic alternative to solid and hydrazine liquid propulsion systems. As the rocket motor fuel is industrial rubber, there are no special handling or transportation requirements, which greatly reduces the lifecycle cost to customers.

Its nice to see the engines going thru their paces - its going to be great to see the DC under her own power - maybe at the end of the upcoming landing and approach tests or maybe under extended milestones.

also, from Nasawatch: John Olson Departing OSTP/NASA to Join SNC.  Considering where he was at, (Director of the Strategic Analysis and Integration Division in the Human Exploration and Operations Mission Directorate) maybe this portends good things to come (why go to SNC if things aren't going to go someplace).

They’re all in a NASA competition and they all are getting NASA’s (the people’s) money, I say they all should get a “meatball”...  ;)
As far as I can tell, it's not that the companies don't want a NASA sticker, it's that NASA doesn't want its name being used as a sort of free advertisement or implied endorsement for something that's actually proprietary.
Funny though that they put them on the Moon Buggy competion vehicles at MSFC...

We should ask Chris to shake the trees and see what falls out about this... ;)

I find this a little (just a little - MDA is well known) surprising, I can think of several American companies that can do this well and maybe add a few congressmen to the DC competition.

Presser:

Sparks, Nev.,– August 19, 2013 – Last week NASA announced that it has added additional milestones to Sierra Nevada Corporation’s (SNC) Dream Chaser® Space Act Agreement (SAA) under the Commercial Crew Integrated Capability (CCiCap) initiative. NASA amended SNC’s SAA to include two additional milestones totaling $15 million, bringing the value of SNC’s CCiCap SAA to $227.5 million.

“SNC is pleased to be awarded this new NASA investment and we will make valuable use of the additional $15 million in funding,” said Mark Sirangelo, corporate vice president and head of SNC’s Space Systems. “The addition of these two funded milestones will allow our team to continue the advancement of the Dream Chaser Space System.”

The two optional milestones will extend the SNC CCiCap period of performance from May 2014 to August 2014, advancing the design and testing of the Dream Chaser Space System. Specifically, the optional milestones will fund work associated with the Critical Design Review (CDR) for the vehicle and additional testing of the reaction control system.

SNC is one of three companies funded under the CCiCap initiative to develop a next generation crew transportation vehicle and the only reusable, lifting body vehicle with runway landing capability. The Dream Chaser space vehicle is on the forefront of the commercial human spaceflight industry, offering safe, reliable, and cost effective crew and critical cargo transportation to low-Earth orbit.

RELEASE 13-33

NASA Partner Completes Second Dream Chaser Captive-Carry Test

NASA partner Sierra Nevada Corporation (SNC) of Louisville, Colo., successfully completed a captive-carry test of the Dream Chaser spacecraft Thursday, Aug. 22, at the agency's Dryden Flight Research Center in Edwards, Calif.

During the two-hour test, an Erickson Air-Crane helicopter picked up a test version of the Dream Chaser flight vehicle and flew it a distance of three miles over a dry lake bed at Edwards Air Force Base at a maximum altitude of approximately 12,400 feet. The spacecraft followed the projected path it will fly during future approach and landing tests at Dryden. Dream Chaser's flight computer, along with its guidance, navigation and control systems were tested. The landing gear and nose skid also were deployed during flight.

"Today is the first time we have flown a fully functional Dream Chaser flight vehicle, and we are very pleased with the results," said Mark Sirangelo, corporate vice president and head of SNC's Space Systems. "Our team represents the very best in collaboration between industry and government. We have worked closely with NASA, Dryden and the Air Force to reach this important milestone in our flight test program. We look forward to seeing Dream Chaser land on the same runway as the space shuttle orbiters once did as we move forward in the development of the next-generation crew transportation vehicle."

This was the second captive-carry test of the Dream Chaser flight vehicle and its first captive-carry at Dryden. Data obtained from the test will provide SNC valuable information about the Dream Chaser hardware and ground operations. The test paves the way for upcoming free-flight tests at Dryden this fall as part of the company's agreements with NASA.

SNC is working with NASA to develop Dream Chaser, planned to launch atop a United Launch Alliance Atlas V rocket, through the agency's Commercial Crew Development Round 2 (CCDev2) and Commercial Crew Integrated Capability (CCiCap) initiatives. New commercial spaceflight capabilities being developed by NASA partners through these initiatives eventually could provide launch services to transport NASA astronauts to the International Space Station from U.S. soil.

"It's great to see real American-made hardware taking flight right here in the U.S.," said Ed Mango, NASA's Commercial Crew Program (CCP) manager. "This is just the start of an exciting flight test campaign for SNC's Dream Chaser at Dryden."

Work leading up to the captive-carry test included an evaluation of the performance of Dream Chaser's braking and landing systems, during ground tow tests, at increasing speeds. SNC engineers also verified the spacecraft's computer and software systems, instrumentation and steering performance. The company held a thorough flight test readiness review with engineers, technical experts and representatives from NASA and the U.S. Air Force.

SNC's CCDev2 Space Act Agreement with NASA is set to culminate with an upcoming approach-and-landing free-flight test at Dryden. SNC also is on track to complete all 12 of its CCiCap milestones by the summer of 2014. All of NASA's industry partners, including SNC, continue to meet their established milestones in developing commercial crew transportation capabilities.

This is very well said

Quote
Often cited as “handing over the keys to Low Earth Orbit (LEO)”, NASA is deeply involved in providing funding and expertise to drive both new and old space companies into providing domestic cargo and crew capabilities to the International Space Station (ISS).

NASA used it best asset - the ISS - to provide a destination for newspace companies.
Today it can be said that, without ISS cargo (and soon crew) supply, private companies wouldn't be on the way to HSF. For example, orbital tourism by itself would not have been sufficient to sustain Dragon (or Dream Chaser) development, not with a dozen of $30 million tickets spread over decades.
I say: this is NASA job as per its charter. To help develop space as, many decades ago, NACA helped aeronautics to develop.

handing over the keys

I like that you pull no punches in your apt description of the post-shuttle transition.  But what concerns me most is that while the commercial crew program is progressing, under the current funding scenario it is progressing toward a dead end for two out of the three contenders. So as the down-select approaches we continue to throw taxpayer dollars down the drain on new systems that will never see the light of day.

Risk-reduction. Besides, it's still possible these systems may eventually see the light of day. Bigelow's inflatable was a canceled NASA project. Even SpaceX's Merlin's early turbopump has intellectual heritage from part of a canceled NASA project. DC-X was cancelled, but inspired Grasshopper and Blue Origin. Blue Origin won't be picked for commercial crew, but the funding from NASA is helping them with their further efforts.

It's not for naught.

Could not have said it any better. If we can only afford one final contract, such is life. At least we got to nurture 3 different vehicles forward, and the private spaceflight industry is a hell of a lot further along than it was (nowhere?) pre-COTS/Commercial Crew. One of the goals of NASA is not only to provide science themselves but to be a catalyst like this.

If I remember correctly, should either a Delta or Atlas not be available, (or the mythical SLS) the Dreamchaser could be launched on a Falcon 9, or was that the Falcon Heavy?

Langley Tests Dream Chaser's Thermal Dynamics
Sept 23, 2013 Sasha Congiu, NASA's Langley Research Center

When Sierra Nevada Corporation’s (SNC) Dream Chaser spacecraft flies through the atmosphere, it will encounter a wide variety of environmental conditions. Any spacecraft traveling at hypersonic velocities must have a robust thermal protection system (TPS) to protect astronauts and cargo from the extreme temperatures associated with ascent and re-entry.

NASA's Langley Research Center in Hampton, Va., recently conducted hypersonic testing of Dream Chaser models for SNC as part of the agency's Commercial Crew Program in order to obtain necessary data for the material selection and design of the TPS. SNC conducted wind tunnel tests to reduce risk and improve the reliability of the Dream Chaser TPS under milestone eight of the agency's Commercial Crew Integrated Capability (CCiCap) initiative.

The Dream Chaser, based on NASA's HL-20 lifting-body design, combines years of NASA analysis and wind tunnel research with SNC engineering, resulting in a reusable spacecraft that could ferry astronaut crews to and from low-Earth orbit. The HL-20 was a space plane concept studied by NASA at Langley during the early 1990s as a safe and affordable personnel launch system for trips to low-Earth orbit.

 “This system, along with other Commercial Crew Program partners' systems, gets us one step closer to launching people back into space onboard American made spacecraft,” said Karen Berger, Langley aerospace engineer.

The Dream Chaser models tested were approximately 10 inches long and made of cast ceramic. They were fabricated at Langley to measure heating levels the Dream Chaser spacecraft would experience during re-entry, including the lower- and upper-body flaps, elevons and a rudder. As with all spacecraft development, the testing required attention to details, from the design of the model to the complexity of data collection and analysis.

The heating data were measured using phosphor thermography, which allowed researchers to see a global view of the surface being investigated. Each pixel in the image acts as its own data point.

“It allows us to see very complex and intricate flow patterns,” Berger said.

With this technique, an image of each model is acquired before each wind tunnel run and then multiple images are taken during the run itself.

“Using calibrations performed prior to the test and calibrating with the color change after the test run, the temperatures and heating rate for each image can be computed,” Berger said.

The temperatures and heating rate information then will be used to help determine appropriate thermal protection system materials and also will be compared with computational predictions. Hypersonic testing of the Dream Chaser spacecraft will enable NASA and SNC teams to advance their knowledge and understanding of the environments that the vehicle will encounter during ascent and re-entry.

“We can use that knowledge to better develop new vehicles in the future, whether they are NASA vehicles or we are working with our commercial partners,” Berger said.

I'm intrigued by the shape of the cowling around the engine nozzles. This has been depicted in models before, but not in CG.

http://www.nasa.gov/sites/default/files/dream_chaser_testing.jpg?itok=KzdVUkwn

After scratching my head for a while I've come up with a theory on what's going on: this is thermal protection for the nozzle during re-entry (they're exposed to the airstream as the nose is pointed up). However, these engines are supposedly support thrust vectoring, and a fixed TPS cowling would prevent movement, so what we see here are separate rings of TPS that can move independent of each other to allow the nozzle to gimbal.

I'm a little surprised they haven't done a material selection for the TPS yet. Maybe there's an error in the announcement ?

Isn't there a bit of weight difference between the various choices, and that would have an effect on other design decisions ?

They are also used in lifting large objects on top of buildings.  A long long time ago in a past millenium, I and several hundred other people had to exit a massive factory while a Sky Crane lifted a huge new air conditioning unit up on the roof.  It was impressive to watch.  There are a lot of uses for these helicopters even when there are no wild fires.

Would a company using the IBDM meet NASA certification requirements?

P.S. Incidentally, it is worth mentionning that your quote comes from page 82 of the ESA Bulletin that you linked.

It appears that what kept Dream Chaser’s landing gear from deploying was contamination in the gear’s hydraulic lines, not a design issue that would slow development of the spacecraft, Sirangelo said. ...

The gist is some European organizations are putting some money into studying the utilization of Dream Chaser as both a manned and unmanned orbital vehicle.  That has to be encouraging news for SNC.  Makes a lot of sense on the European side especially if they launch it on an Ariane.

This article was linked in the discussion thread but it also belongs in the update thread as it is an important development.

Meanwhile, SNC plans to repair the Dream Chaser test vehicle damaged in the Oct. 26 drop test. “After the post flight evaluation, the vehicle was deemed to be fully repairable and a schedule to return it to flight has been created,” Mark Sirangelo, corporate vice president for Sierra Nevada Corp. and head of Sierra Nevada Space Systems, wrote in a Dec. 17 email. “SNC expects to fly this test vehicle back at Edwards Air Force Base upgraded with additional capability in 2014.” The exact date for the test article’s next flight test has not been settled upon, Sirangelo added.

Nope. ESA does not 'compete' in manned space flight with any other space agency (or country). This is about what ESA has been doing for a long time: cooperate with other space agencies AND commercial parties to achieve it's goals in space.
My bet that this is either the formal anouncement of the study-contract (involving, ESA, DLR and Sierra Nevada) or the preliminary results of that study. The study was contracted out last november.

Would the ESA purchase their own flights to the ISS, or would they use Dream Chaser for standalone LEO science missions ?

Of course, the best part of this news is that it gives the Dream Chaser program additional funding, and will help move it to completion.

This was discussed on L2 previously. It's probably what Woods said. No more. There is a big difference betwen a study and an actual crew transportation contract with ESA.

While still a rumor:

Quote
A potential scenario that has been put forward by sources claims two providers may survive, one at full funding, another with half funding – the “1.5″ scenario. It has also been suggested that SpaceX and SNC are classed as the front runners.

So even with less funding than Boeing, SNC has shown tenacity, technical prowess, and most of all the savvy business skills to come from behind it would seem.  Of course the real test will be when CCtCap reviews all the proposals.

Apparently Bob Cabana gave Steve a hard time when Steve was a young astro.

Wanted to work for SNC because he wanted to sustain HSF and the legacy of Shuttle (lifting bodies).

SNC purchase of the Atlas V was company to company, directly.

Mark isn't giving a direct answer to the funding, but keeps saying they are committed to the launch....

ULA still working with CST-100 for their debut launch.

First flight will be uncrewed, several orbits, not to the ISS, land on the West coast.

Title: Re: SNC Dream Chaser UPDATE Thread
Post by: Malderi on 01/23/2014 09:22 PM
My *guess* would be that this is still a single-engine centaur flight. The reason being, if it was DEC, ULA would've made a bigger deal of it. They've always advertised it, but never finished development because there was never a customer. I suppose the 2017 manned flight will need it, but 2016 unmanned won't. SN may have chosen to defer those costs out a little farther (like, for when they have the NASA money from the next round...)

Press release:

RELEASE 14-030

Sierra Nevada Corporation Announces New Space Plans for NASA's Kennedy Space Center

In the latest example of NASA Kennedy Space Center's transformation into a multi-user spaceport, Sierra Nevada Corporation (SNC) of Louisville, Colo., announced Thursday steps it will take to prepare for a November 2016 orbital flight of its Dream Chaser spacecraft from Florida's Space Coast.
The announcement included the purchase of an Atlas V rocket from United Launch Alliance (ULA) for the launch, sharing the Operations and Checkout (O&C) development and testing facility with Lockheed Martin Space Systems, establishing an operation center at Kennedy Space Center and using the former Shuttle Landing Facility (SLF) runway at Kennedy. The steps are considered substantial for SNC and important to plans by NASA and Space Florida for Kennedy's new availability to both commercial and government customers.                                                                             
"Today's announcement is the latest major milestone in the transformation of the Kennedy Space Center into a 21st century launch complex, serving both private sector and government users," said NASA Administrator Charles Bolden. "I salute Kennedy Space Center Director Bob Cabana for his leadership in transitioning the space coast for the future, and applaud Sierra Nevada Corporation on their decision to carry out their ground-breaking work at Kennedy."
SNC said it plans to work with ULA to launch the company's winged Dream Chaser spacecraft into orbit from Space Launch Complex 41 at Cape Canaveral Air Force Station.
"SNC is thrilled to confirm a launch date for our country’s return to orbital human spaceflight and the restart of human spaceflight operations from Florida’s Space Coast," said Mark Sirangelo, corporate vice president and head of SNC’s Space Systems. "We could not have done this without the spirit and engagement from our national and state governments, the best aerospace companies in the industry, and several major universities, which all hail from over 30 states. Together these passionate people will return our astronauts to space on American spacecraft and rockets launched from America’s space coast right here in Florida."
The Dream Chaser spacecraft is designed to carry crew and critical cargo to destinations, as well as perform servicing and science in low-Earth orbit. SNC said intends to complete Dream Chaser missions with a landing on the 3.5-mile runway at the SLF. Space Florida, which will operate the SLF in the future, will negotiate the terms and conditions for the runway's use with SNC.
"We are pleased to see continued growth of the State's investment into KSC facilities like the O&C," said Space Florida President Frank DiBello. "It is clear that the future of commercial space growth is happening right now in Florida and we couldn't be happier to work with companies like Sierra Nevada to realize their Florida-based expansion goals."
The company said it plans to prepare the Dream Chaser spacecraft in the high bay of the O&C building at Kennedy, with Lockheed Martin performing the work. The facility also is used for the development, assembly and testing of NASA's deep-space Orion spacecraft. Dream Chaser testing will take place without disrupting Orion, NASA's flagship human exploration vehicle.
"The O&C is a state-of-the-art facility that will greatly enhance Dream Chaser’s future operations through an innovative co-use plan with Orion," said Vice President and General Manager, Civil Space, Lockheed Martin Space Systems, James H. Crocker. "The result will maximize efficiency for both the Dream Chaser spacecraft and Orion and will provide continuity for our highly trained, motivated and certified workforce."
SNC also plans to lease office space at Exploration Park, located just outside Kennedy’s gates.
"We have been diligent in our efforts, and I consider this a strong vote of confidence from a company that expects to be a major force in the future of human spaceflight," said Bob Cabana, Kennedy center director. "Sierra Nevada Corporation will find in our workforce and facilities the same dynamic and professional people who have made successful missions from here for more than 50 years."
Cabana said SNC's involvement with the Florida spaceport shows the conversion to a 21st century spaceport is succeeding, although work remains to keep the transformation on pace.
"We are honored that Sierra Nevada Corporation has reserved a proven Atlas V to launch its first flight test in 2016,” said Michael Gass, United Launch Alliance president and CEO. “With 42 successful missions spanning a decade of operational service, the commercially-developed Atlas V is uniquely qualified to provide launch services for the Crew Transportation System. Because Atlas is already certified by NASA to fly the nation’s most complex exploration missions, ULA is able to provide a wealth of flight data, design implementation, detailed system and subsystem analysis, qualification and certification documentation to support the Atlas V for human spaceflight."
The Dream Chaser spacecraft is deep into development of flight hardware and specific plans ranging from ground support equipment to what to include in a mission operations center.
"I had the privilege of piloting and commanding five space shuttle flights as a NASA astronaut," said Steve Lindsey, former NASA astronaut and SNC’s senior director and Dream Chaser program manager. "This included the last flight of Discovery which was processed, launched, and on March 9, 2011, made its final landing at the SLF after 39 flights and 148 million space miles.  Mark, the entire SNC Dream Chaser team, and I look forward to seeing Dream Chaser continue this legacy from Discovery when it flies in 2016."

Quote from: DC article
In a sign of SNC’s commitment to flying Dream Chaser in space, this (AtlasV) launch is not understood to be subject to their Commercial Crew funding with NASA, with long lead procurements already lined up.

That's a big deal. I was kind of wondering about that. It seems SNC is really commited to DC regardless of what happens during CCtCap. That's a big plus for DC, if NASA sees SNC as fully commited to finishing DC regardless of whether they get partial, full or no funding, this could actually increase the chances of SNC for CCtCap. I believe that skin in the game will be given more weight in the next round.

I can't wait for the next flight of the ETA.
BTW, what does SNC envision as the DC version of the SCA? Just like for Shuttle, the SLF will not always be an available landing strip because of weather and diverts to California will be SOP in that case.
 
Thanks for a great write-up Chris.

Thanks for the above! :) Another milestone for SNC, but not enough for another article based on the presser:

 Sierra Nevada Corporation Enters Dream Chaser® Critical Design Review
Completes NASA CCiCap CDR Entry Milestone

Sparks, Nev., January 30, 2014 – Sierra Nevada Corporation (SNC) announces the completion of the Dream Chaser® Incremental Critical Design Review (CDR) with the completion of Milestone 10a under its Commercial Crew Integrated Capability (CCiCap) agreement with NASA.

Mark N. Sirangelo, corporate vice president and head of SNC’s Space Systems made the announcement at the Annual Reliability and Maintainability Symposium (RAMS®) during his keynote address. RAMS is the premier event in the reliability, availability, and maintainability engineering disciplines. The RAMS event attracted hundreds of safety and reliability practitioners and engineering leaders from around the world.

“SNC’s Dream Chaser program continues its steady progress forward on the way to flight certification by completing this important milestone which begins our Dream Chaser Critical Design Review process,” said Sirangelo. “SNC is firmly committed to providing the safest, most reliable, and efficiently maintainable orbital transportation system with, the Dream Chaser Space System, by having the most experienced technical, safety, reliability and quality assurance team possible. The team is definitely ensuring that we incorporate the latest technology from all of these processes into SNC’s design.”

NASA added Milestone 10a to SNC’s CCiCap initiative in 2013 as part of the expansion of SNC’s program.  During this entry milestone review, NASA approved the critical design products, plans, and processes that are being used to develop the Dream Chaser Space System (DCSS), which includes the Dream Chaser spacecraft, Atlas launch vehicle, mission and ground systems. The CDR level products will also support the subsystem and element critical design reviews that are occurring throughout the year and culminating with system level reviews scheduled to ensure all technical performance requirements are met while meeting Dream Chaser Program schedule and budget. The DCSS fabrication, assembly, integration, and test process has begun to support the recently announced November 2016 orbital launch.

John Turner, SNC’s director of safety and mission assurance for the Dream Chaser program, and member of the RAMS management committee added his thoughts, “I had the privilege of spending over 26 years at NASA working on planning, development, operations and safety aspects of the space shuttle, International Space Station, and Constellation Human Spaceflight programs. My main focus was and remains to ensure that all flight programs were safe, successful and exceeded mission targets.  We are incorporating those best practices and lessons learned into our CDR processes for the Dream Chaser. We also have a world class team with strong experience in safety and risk management to ensure that we certify Dream Chaser as the safest human spaceflight vehicle yet to fly.”

David Oberhettinger, the general chair of the RAMS® 2014 symposium held in Colorado Springs, Colo., noted, “RAMS® is excited to have companies like SNC participate in our annual conference and benefit from the unique opportunities that we offer. Conference participants gain insights into latest advances in the field of reliability and maintainability than can be immediately applied to assure high product reliability, safety and mission success.”

Is it safe to say that the OTV construction will proceed and the Atlas V flight is funded regardless of pending commercial crew awards?  If so, that certainly boosts my optimism and I'm looking forward to watching this program continue to progress.  I visited Discovery at Udvar Hazy a few days ago and I was a little less sad seeing her in a museum knowing that there may in fact be a light at the end of the tunnel!

I wouldn't bet on it happening. It is a firm mark of intent, but I don't think it would be the first LV order to be cancelled or withdrawn if that is what ends up happening. (hopefully not)

As far as funding, it would presumably be indirectly be funded by future CCtCap milestones/payments from NASA. SnC has likely raised the initial funds on its own, with the expectation that future NASA payments would recoup that investment.

You do indeed get to ~16m^3 by assuming an average pressure vessel diameter of 5.5ft and a length of 24ft, which seems plausible. This compares to 10m^3 for Dragon.

Or it could have been taken when it first arrived at Dryden last year. Based on plastic on the ground I think this is unpacking rather than packing.

I can understand SNC not wanting to release pictures of a beaten up DC, but I would have thought it would be in a photogenic state by now - i.e. in pieces and under construction.

This is a picture of the unpacking and assembly at Dryden(?). Not after the bad landing.

A presser from SNC. Doesn't really say anything, unless I'm missing something.

Sierra Nevada Corporation and Lockheed Martin
Expand Dream Chaser Orbital Vehicle Manufacturing

Sparks, Nev., March 25, 2014 – In a press conference held today at the Michoud Assembly Facility (MAF) in Michoud, La., Sierra Nevada Corporation (SNC) and Dream Chaser® strategic partner Lockheed Martin announced the expansion of SNC Dream Chaser spacecraft orbital vehicle manufacturing operations.

As a valued member of SNC’s Dream Chaser Dream Team, Lockheed Martin is under contract to manufacture the next Dream Chaser composite structure which will be for the first orbital vehicle scheduled to launch on November 1, 2016. The MAF, which is owned and operated by NASA’s Marshall Space Flight Center, has been operational since 1961 and has played a significant role on our nation’s space programs ranging from Apollo to the space shuttle. Today, leveraging the experience, technical expertise and current infrastructure at Michoud, next generation vehicles such as SNC’s Dream Chaser and Lockheed Martin’s Orion are being fabricated within the same walls as   legendary programs.

“Michoud and the state of Louisiana, have a vital role in our nation’s space program,” said Mark N. Sirangelo, corporate vice president and head of SNC’s Space Systems. “We look to continue this valuable role through our partnership with Lockheed Martin for the build of our next Dream Chaser composite structure at the Michoud Assembly Facility.  We will be utilizing MAF’s existing facilities, partnerships and the workforce of Louisiana to bring America’s future transportation vehicles for low-Earth orbit  to reality while continuing to expand the Dream Chaser program footprint, which now provides employment in over 30 states.”

SNC chose Lockheed Martin to manufacture the Dream Chaser orbital composite structure based on their rich human spaceflight manufacturing heritage, including building the External Tank for the space shuttle program, and their  work for  the Orion program Fabricating key elements of Dream Chaser structures at MAF leverages Orion manufacturing efforts currently underway, while also taking advantage of existing facilities, relationships and assets, such as the National Center for Advanced Manufacturing (NCAM).

“Lockheed Martin’s history at MAF brings a wealth of experience to the Dream Chaser program,” said Jim Crocker, vice president of Lockheed Martin’s Space Systems Company Civil Space Line of Business. “Not only are we leveraging manufacturing processes and technology, we are also leveraging the Human Rating Certification methodology developed by the Orion program, which was then tailored to Dream Chaser.”

Currently, the Dream Chaser spacecraft orbital vehicle is in the early stage of the fabrication process at MAF. Fabrication of composite structures started in January 2014 with cabin ring frame production at MAF. Complex part fabrication will begin upon receipt of tooling in April 2014. As each composite structure is completed, it will then be shipped to Lockheed Martin’s facility in Fort Worth, Texas, for assembly and final inspection before being released to SNC.

Reading that, including Michoud in the production process seems very inefficient. LM has ample composite manufacturing capability in Fort Worth for its military aircraft productions. The only value added by Michoud is probably political.

No, the tooling at Forth Worth is specific to their aircraft lines and that facility is busy with the JSF currently. MAF has the excess capacity and is a naturally place to build the airframes.

It is not political.

1.  Fort Worth is not the center of LM composite'
3.  LM has a manufacturing presents at MAF already.  And it does spacecraft.
4.  This is a way of sharing a workforce.

We are building one Orbital Test Vehicle that will launch on an Atlas V in 2016 (press releases are out on this already).  Phase 2 would have us building 3 more,  but I think downselect is slated for August/September timeframe. 

LM owns a small amount of tooling used on the program, all tools built specifically for this program are delivered in place, meaning they will stay where they were used unless SNC asks for them.

Sierra Nevada Corporation and Houston Airport System
Sign Letter of Intent to Explore Dream Chaser® Teaming Opportunities
at the Houston Space Port

Sparks, Nev., April 10, 2014 – In a joint news conference held today at the Rice University Space Institute, Sierra Nevada Corporation (SNC) and the Houston Airport System (HAS) announced plans to explore potential applications and multiple economic development opportunities presented by the combination of a Houston-based space port and SNC’s Dream Chaser® - a spacecraft that can land at the space port directly from low-Earth orbit.

SNC and HAS signed a letter of intent to work together to explore the possibilities associated with the proposed Houston Space Port including a wide range of educational, technological, scientific and business capacities. As part of the cooperative initiative, the organizations will study the physical, operational and regulatory requirements for SNC’s commercial space vehicle, Dream Chaser, to utilize the space port as one of its potential landing sites. This effort will contribute to defining a long range strategy for the diversification and development of a vibrant commercial space industry in Texas, serving the needs of government, science, and commercial applications.

“Houston has been a cornerstone of America’s space program and remains vital for its future.  Dream Chaser’s ability to land on a commercial runway such as Ellington offers, for the first time, a realistic path for America’s space program to return and be seen locally by the thousands of people who make space happen every day in Houston and give tribute to the generations that have made us the leaders in exploration,” said Mark N. Sirangelo, corporate vice president and head of SNC’s Space Systems. “As importantly, we can reach out to the young people of the region who will take us to the future and get them to experience in person the passion of our nation’s space program so that they might be inspired as we were.  With the unique combination of NASA, the local aerospace industry, many of whom are already partnered on our program and academic institutions such as Rice University, combined with the potential of a future space port, Houston’s future in space commerce is a go.”

“Houston has unique advantages over other emerging spaceport locations with significant access to an existing, robust aerospace community,” said City of Houston Aviation Director Mario Diaz. “This letter of intent will allow us to effectively assess and define the new markets and applications that could emerge from having a Houston-based portal to space, which in turn will drive enterprise, economic growth and prosperity in this area.”

SNC is working with NASA’s Commercial Crew Program to develop a safe, innovative, modern, flexible and highly-capable crew transportation system for the 21st Century. Dream Chaser provides the only reusable, human-rated lifting-body spacecraft with a commercial runway landing capability, anywhere in the world, and is on the forefront of the commercial human spaceflight industry, offering safe, reliable and cost-effective crew and critical cargo transportation to low-Earth orbit. Dream Chaser is a multi-mission capable spacecraft which has the ability to work as an independent science platform, or as a logistics vehicle to retrieve, move, assemble or deploy items in space.

Interesting development, but it seems the disadvantages of building spacecraft and payload support infrastructure as well as a transportation system to return the vehicle to Florida would outweigh the benefits of showing support to the good spaceflight and NASA loving people of Houston. Flying approaches of an unpowered space glider over the densely populated suburbs of Houston will also raise a few eyebrows at the FAA licensing division. It appears to be a marketing/political support garnering piece to me as well.

Sierra Nevada Corporation Ranked as one of “World’s Top 10 Most Innovative Companies in Space” by Fast Company Magazine

Sparks, Nev. – April 15, 2014 – Sierra Nevada Corporation (SNC) President, Eren Ozmen, proudly announced that Fast Company magazine ranked SNC  as one of the “World’s Top 10 Most Innovative Companies in Space.”

Fast Company recognized SNC for “resurrecting the spaceplane” calling SNC’s Dream Chaser® spacecraft the, “…biggest contribution to the nascent commercial spaceflight industry” and the “…smaller, and arguably smarter take on the defunct Space Shuttle.”

"We are thrilled that the work we are doing to continue the legacy of the Space Shuttle and space planes through the development and now flight testing of Dream Chaser has been recognized by Fast Company. Through the previous foundational work of NASA and continuing on with the amazing collaboration of team members in 30 states working for 15 companies, eight NASA Centers and six universities - our “Dream Team,” we expect to conduct our first orbital mission in 2016," said Mark N. Sirangelo, corporate VP and head of SNC Space Systems.

The Dream Chaser spacecraft can carry up to seven crew members, or can fly completely autonomously with no crew.  It is designed to ride into orbit atop existing rockets, and then glide home and land on any standard, commercial runway - unlike the Shuttle, which required longer landing strips and special hazardous vehicle processing ground equipment. The SNC spacecraft is on track to carry NASA astronauts into space in 2017, with the first uncrewed orbital vehicle scheduled to launch in November 2016.

In this publication, SNC was also recognized for its work on hybrid rocket motors. SNC’s Space System team builds the hybrid rockets used on Virgin Galactic’s suborbital spaceplane, SpaceshipTwo (SS2), which were flight-tested for the first time this past year and have successfully powered three SS2 test flights.

I believe this would count as an update...

Something I've known about for ~1 month or so. I was told at the time that this was private, so I didn't share. However, the Maryland Day open house on the University of Maryland's campus made it public, so I feel comfortable putting these up:

DC is at the University of Maryland Space Systems Lab! (Granted, it's a subscale full-scale! model without wings/stabilizers.) I don't really know any details at all, as I'm just a lowly undergrad, but my best guess is that it will be tested in the SSL's neutral buoyancy facility, considering it was parked in the facility's high bay. (Really, what else do we have that SNC couldn't get otherwise?) For the open house, though, it was carted out and put on display!

Here's the pics: (I apologize for the blurred out images; I don't want to post images of random people online...The geek in the green shirt, though? That's me.)

Part of the problem is the editing: fractions of different sentences have been cobbled together to make wholes, presumably in order to create a piece that runs quickly, and concludes in just two and a half minutes.

The "20, 30 or 40 capsules" remark does sound strange, but that phrase was clearly spliced onto the end of the prior comment in post. Even so, it doesn't actually make sense.

Since we don't know what he actually said in context, it's hard to judge. The same goes for the iPad versus apps comment.

SNC's Roth also mentions they are in talks with companies who might offer DC for high-speed point-to-point suborbital flights starting with air-launch. (Listen at ~53min).

This has come up before, and the consensus was it's problematic at best. At a minimum it involves the development of an expendable boost stage - which must not land in someone's garden. Then there's the problem of the launch aircraft (presumably VG is still keeping WK2 to themselves). Routes would likely be limited and so this would be more of an expensive thrill-ride than a replacement for air travel.

Don't forget DC has 2 big hybrids built in. Drop it from WK2 at 50,000 ft and fire them how far could it go? What of they sub in XCOR or Virgin's liquids?

I am neither a rocket nor aerodynamic scientist but we have some specs;
DC has L/D of roughly 4.
now the arm waving;
WK can take the DC to 50,000 ft. (?)
The rockets can get the DC to Mach 2 (?) and 100,000 ft. (?)
How long will the rockets fire (?)
with this it should be possible to model a flight path (?)

Post by: FinalFrontier on 05/15/2014 02:54 PM
Questionn for the thread and those following SNC more closely at large:

Worst case scenerio lets assume recent developments ultimately force a cease in flights of the Atlas V either because domestic engine production for RD180 never occurs or it does not begin to show results until 2019-2020 ish.


What changes are needed, if any, in order for SNC to adapt the DC for another vehicle so it can still, more or less, fly on schedule? And yes I know this might be contingent on the vehicle. The obvious choice everyone would ask is a Falcon 9 of some sort since its going to be human rated for Dragons flights anyway. I submit possible orbital rockets as a second choice however, as well as DIV in this question.
Title: Re: SNC Dream Chaser UPDATE Thread
Post by: adrianwyard on 05/15/2014 03:10 PM
Re launchers: SNC have said all along that DC is launcher agnostic, and just yesterday SNC's John Roth mentioned F9 as a possibility. However AFAIK the only wind tunnel testing they've done has been on Atlas/Centaur.

I'm reminded this is the Update thread, so perhaps follow-ups to this should go to the Discussion thread here: http://forum.nasaspaceflight.com/index.php?topic=29417.525

I think that propulsive landing like the Dragon will have is pretty cool too and will allow for more choices for the landing. I guess it is a matter of taste. I do find the DC a lot more appealing than the CST100 though.

I don't think of it as a detriment to the article that you were explicit in describing the situation as it stands, with the "competitors" battling out and the time constraints... it was a full and I believe accurate article.... one that needs to be published now, (for those that read only the articles) as we close in on the political (congress) encouraged down select... I am truly hopeful that all will eventually find a place in Space Transportation, regardless of the winner of the contract to ferry astronauts to the ISS...

From the article:

"The plan, according to SNC, is to fly an internally selected crew of astronauts on that vehicle at the end of 2016". 

So does this mean the first flight will be manned?  Or does this mean the above will happen only if they survive the down select, and there will be an unmanned orbital test flight prior regardless?

Because rumor has it the HTPB-based SS2 motors had vibration and/or performance issues, and best guess is the DC motors are similar in size. DC has a carbon composite structure like SS2, and so could have similar vibration tolerances.

On the other hand SNC has already passed CC payment milestones for HTPB motor demonstrations. If these were instrumented for vibration, then there's no cause for concern...

FOR IMMEDIATE RELEASE
June 12, 2014

Sierra Nevada Corporation Adds Craig Technologies to Dream Chaser® Dream Team

Sparks, Nev., June 12, 2014 – Sierra Nevada Corporation (SNC) announces it has selected Craig Technologies of Cape Canaveral, Florida, to join its expanding list of ‘Dream Team’ organizations selected to support SNC’s Dream Chaser® program.  SNC is developing the Dream Chaser spacecraft as a commercial transportation vehicle to low-Earth orbit.  Craig Technologies will provide multiple contracted products and services to SNC. The announcement was made at a press conference today at Craig Technologies Aerospace and Defense Manufacturing Center in Cape Canaveral.

Craig Technologies’ first contract is to work with SNC engineers to design and develop a critical part of the Ground Support Equipment (GSE) known as the cradle, a mechanical device used to lift, transport and rotate the Dream Chaser spacecraft during processing. SNC chose to team with Craig Technologies on its Dream Chaser program because of their depth of human spaceflight experience coupled with their end-to-end design-to-production capability including specialty manufacturing, precision machining and fabrication, and test and evaluation services, as well as materials requirement planning and supply chain management systems.

“Today is the start of a relationship that can grow substantially as a continuation of our expansion in Florida” said Mark N. Sirangelo, corporate vice president of SNC’s Space Systems. “We are pleased to have Carol (Craig) and her company join forces as part of our Dream Team, which includes top tier companies in over 30 states. Craig Technologies’ strong engineering capabilities and outstanding facilities along with their company values and passion are an ideal fit for SNC and our Dream Chaser program. We look forward to exploring ways in which we can continue to work together, returning jobs to the Space Coast and continuing our commitment to small business.”

In support of Craig Technologies continual growth as a leading U.S.-Owned, Minority-Owned, Service-Disabled Veteran-Owned (SDVO), Economically-Disadvantaged Woman-Owned Small Business (EDWOSB), and Small Disadvantaged Business (SDB), SNC has agreed to sponsor Craig in a mentor-protégé relationship, supporting a common vision of providing each of SNC’s and Craig Technologies’ customers with agile, innovative and cost-effective solutions from a richly diverse and passionately dedicated workforce, all committed to making history.

Craig Technologies recently invested in the renovation of an existing 161,000 square foot facility in Cape Canaveral.The company leveraged NASA’s investment by utilizing the heritage space shuttle depot facility formerly occupied by United Space Alliance and converting it to office and manufacturing space, including the latest high tech, high precision, manufacturing equipment.

“To partner with the SNC Dream Team who marries ‘innovation with passion for the mission’ provides us an opportunity to fulfill our vision to further strengthen the Space Coast community,” said Carol Craig, founder and CEO, Craig Technologies.

Dream Chaser provides the only reusable, human-rated lifting-body spacecraft with a commercial runway landing capability, anywhere in the world, and is on the forefront of the commercial human spaceflight industry, offering safe, reliable and cost-effective crew and critical cargo transportation to low-Earth orbit. Dream Chaser is a multi-mission capable spacecraft that has the ability to operate as an independent science platform, or as a logistics vehicle to retrieve, repair, replace, assemble or deploy items in space.

Sparks, Nev., July 8, 2014 – Sierra Nevada Corporation (SNC) announces it has completed a major Main Propulsion System (MPS) and Reaction Control System (RCS) risk reduction milestone for the Dream Chaser® Space System, maturing the design of each system close to Critical Design Review (CDR). The milestone positions SNC one step closer to restoring U.S. crew transportation to low-Earth orbit (LEO).

SNC completed the work for milestone 9a under its Commercial Crew Integrated Capability (CCiCap) agreement with NASA. In total, SNC has received over 80 percent of the total award value of the CCiCap agreement having successfully completed 10 of 13 milestones.

The Main Propulsion System is based on SNC’s patented rocket motor technology. To date, SNC has performed hundreds of rocket motor test firings at its Poway, California, facility advancing the motor technology with each test. The Dream Chaser MPS will not only power the spacecraft in orbit, it also offers a unique abort capability while on the launch pad and throughout the flight trajectory, unlike human space transportation capsules. The MPS technology used on the Dream Chaser results in a safe runway landing during an abort scenario, further reducing risk to the crew, spacecraft and payload.

The RCS, which is being designed by Orbital Technologies Corporation (ORBITEC), will provide precise on-orbit control of the Dream Chaser spacecraft. The RCS will provide maneuvering capability to allow for the accurate docking of the Dream Chaser to destinations in low-Earth orbit. Dream Chaser is a multi-mission capable spacecraft that has the ability to operate as an independent science platform or as a logistics vehicle to retrieve, repair, replace, assemble or deploy items in space.

“Safety is paramount in the design of the Dream Chaser Space System,” said Mark N. Sirangelo, corporate vice president of SNC’s Space Systems. “It is driven by reliability, rigorous quality assurance, consistent performance and extensive testing and analysis. In passing this milestone we are able to validate our safety and performance, while decreasing the risk for each of these systems. Completing this milestone moves the Dream Chaser closer to the Critical Design Review of our complete system.”

SNC is working with NASA’s Commercial Crew Program to develop a safe, innovative, modern, flexible and highly-capable crew transportation system for the 21st Century. Dream Chaser provides the only reusable, human-rated, lifting-body spacecraft with a commercial runway landing capability, anywhere in the world, and is on the forefront of the commercial human spaceflight industry, offering safe, reliable and cost-effective crew and critical cargo transportation to LEO.

Looks like if Serria Nevada doesn't have the expertise in a particular field they need to get into, rather than outsource the work, they buy the company and keep it all inhouse.  Pretty clever, and keeps overall costs down.

Sierra Nevada Corporation Announces Cooperative Understanding with
Japanese Aerospace Exploration Agency for the
Dream Chaser® Space System

Sparks, Nev., July 23, 2014 – Sierra Nevada Corporation (SNC) announced today the expansion of its Dream Chaser® Space System’s global partnership to include Asia and the Pacific Rim through a recently signed memorandum of cooperative understanding with the Japanese Aerospace Exploration Agency (JAXA). SNC will work with JAXA on potential applications of Japanese technologies and the development of mission concepts for the Dream Chaser spacecraft.  Additionally, SNC and JAXA will explore the possibility of launching and landing the Dream Chaser spacecraft in Japan. This international collaboration will widen the breadth of the global capabilities offered by SNC’s Dream Chaser reusable, lifting-body spacecraft.

Currently, the Dream Chaser is undergoing development and flight test preparations to transport astronauts from the United States and partner nations to low-Earth orbit (LEO) destinations, such as the International Space Station (ISS).  The first Dream Chaser orbital launch is scheduled for November 2016.  Beyond the technical collaboration, the cooperation seeks to maintain and strengthen the existing global space partnerships established between Japan and the U.S.

JAXA joins the expanding SNC international team that includes the European Space Agency (ESA) and the German Space Agency (DLR).  SNC is confident that the expertise the Japanese bring will further advance the development of the Dream Chaser spacecraft, while providing JAXA access to Dream Chaser flights to advance its space technologies, flight opportunities and space interests in LEO.

“We are excited about the potential of this new relationship with Japan,” said Mark N. Sirangelo, corporate vice president of SNC’s Space Systems. “This expands our global Dream Chaser Space System partnerships to include another major ISS partner with demonstrated capabilities that significantly advance space education and exploration. Japan, like the United States, has the infrastructure to support both launch and landing of the Dream Chaser spacecraft within its own borders.”

SNC’s Dream Chaser Space System is at the forefront of the commercial human spaceflight industry offering safe, reliable and cost-effective crew and critical cargo transportation services to LEO. As the only lifting-body, low-g reentry spacecraft with the capability to land on commercial runways, anywhere in the world, Dream Chaser is uniquely adaptable to meet a variety of mission requirements to retrieve, repair, replace, assemble or deploy items in space, making it the only multi-mission space utility vehicle in the world.

This sounds more interesting that the DLR/ESA agreement. It would be cool to see DC launch from Japan and the United States. This is exactly what commercial crew should be abound: finding new markets for commercial spacecrafts.  Japan has always wanted an independent human spaceflight program. It is still not clear if they will go ahead with their HTV-R.

Mulitple senior officials at NASA are on record multiple times saying that they expect at most two CCtCap awardees. CCtCap award is expected "this summer"/"later this year" depending who's talking. Could providers that don't win a CCtCap contract get on-ramped back in later? Possibly, but for now CCtCap is the gate providers must go through to survive (it is also possible for CCtCap awardees to not receive post-certification mission task orders).

Some theoretical foreign launch that SNC just announced they could maybe do someday if everything works out is not going to swing a massive contract apparatus that is lurching towards its conclusion. The proposals have long since been submitted.

Officially, they have always said one or more providers will be selected. They have never officially stated that they would only select two. Unofficially, they have occasionally admitted that is likely to be two. In the FY 2015 Budget, the Administration said that it was looking into delaying downselection (by extending CCiCap). The amount of awardees will ultimately be decided by the selection officer. The time of the award is still in September. Given recent efforts to derail commercial crew, I suspect that NASA will stick to the September date for the CCtcap award in order not give detractors in Congress more time to further sabotage the program.

As far as the agreement with JAXA is concerned, I am guessing that SNC already included in their proposal that they are trying to find customers outside of NASA.  It adds credibility to their claim.

Sierra Nevada Corporation and Lockheed Martin Unveil
First Dream Chaser® Orbital Spacecraft Composite Structure 

Sparks, Nev., Aug 1, 2014 – In a joint press conference, Sierra Nevada Corporation’s (SNC) Space Systems and Dream Chaser® program partner, Lockheed Martin unveiled the Dream Chaser orbital spacecraft composite airframe. This structure will be used to conduct the first orbital launch of the Dream Chaser spacecraft due to launch in November, 2016, atop a United Launch Alliance Atlas V rocket.

“As a valued strategic partner on SNC’s Dream Chaser Dream Team, Lockheed Martin is under contract to manufacture Dream Chaser orbital structure airframes,” said Mark N. Sirangelo, corporate vice president of SNC’s Space Systems.  “We competitively chose Lockheed Martin because they are a world leader in composite manufacturing, have the infrastructure, resources and quality control needed to support the needs of an orbital vehicle and have a proven track record of leading our nation’s top aviation and aerospace programs. Lockheed Martin’s diverse heritage coupled with their current work on the Orion program adds an extra element of depth and expertise to our program.  SNC and Lockheed Martin continue to expand and develop a strong multi-faceted relationship.”

Earlier this year Lockheed Martin began fabrication of the Dream Chaser orbital spacecraft structure at the Michoud Assembly Facility (MAF) in New Orleans, Louisiana.  The MAF, which is owned and operated by NASA’s Marshall Space Flight Center, has played a significant role in our nation’s space programs from Apollo to the space shuttle, and most recently, Orion spacecraft manufacturing. As each Dream Chaser structural component completes the fabrication and inspection process at MAF, it is transported to Lockheed Martin’s Aeronautics facility in Fort Worth, Texas for integration into the airframe and co-bonded assembly.

Lockheed Martin’s Fort Worth facility manufactures and assembles the world’s top fighter aircraft, the F-35 Lighting II and the F-16 Fighting Falcon. Combined with technology mastered at Lockheed Martin’s Skunk Works®, the Dream Chaser team is able to leverage their extensive experience in the areas of composites and advanced manufacturing to ensure the Dream Chaser orbital structure is fabricated, built and assembled using best practices. In addition, Lockheed Martin is applying advanced 3D preform technology for joint assembly thereby reducing overall part and tooling count while improving assembly and integration time. Through these improved processes, SNC and Lockheed Martin are able to improve the overall durability, weight efficiency and affordability of the spacecraft.

“Lockheed Martin’s depth of aviation and aerospace experience brings a wealth of expertise to   the Dream Chaser composite structure development,” said Jim Crocker, vice president of Lockheed Martin’s Space Systems Company Civil Space Line of Business. “We are able to tailor our best manufacturing processes, and our innovative technology from across the corporation to fit the needs of the Dream Chaser program.”

In addition to the current Dream Chaser airframe manufacturing work, Lockheed Martin is also supporting SNC in the areas of vehicle assembly, integration, environmental testing, ground support equipment, flight certification and spacecraft launch and recovery. This work is performed at various Lockheed Martin facilities in Louisiana, Texas, Florida and Colorado. 

Upon completion of manufacturing Lockheed Martin will transport the Dream Chaser airframe to SNC’s Louisville, Colorado, facility for final integration and assembly.

SNC is working with NASA’s Commercial Crew Program under an existing space act agreement to develop a safe, innovative, modern, flexible and highly-capable commercial space transportation system for the 21st Century. Once developed, Dream Chaser will provide the only reusable, human-rated lifting-body spacecraft with a commercial runway landing capability, anywhere in the world, and is on the forefront of the commercial human spaceflight industry, offering safe, reliable and cost-effective crew and critical cargo transportation to and from low-Earth orbit.

At the end of the show, Sirangelo says that there will be a launch abort test as part of their CCtCap proposal. He also said that there was 18 to 22 RCS thrusters and that the RCS and the main motors would use the same type of fuel which is a non-toxic fuel system. The main motors are re-startable and throttable.

Do they need to?  Main engines are used to reach orbit or for the LAS, are they needed to de-orbit?

Yes, Dream chaser uses its twin engines both for final orbit insertion and for de-orbit. The SNC ConOps video shows this very well. If I can find it quickly I'll post the link to it.

From the comments section of the Parabolic Arc article (in answer to my question about the main engines):

Quote from: Charles Lurio
[...] nitrous-propane is what I was told and printed in my July Lurio Report. You can see the advantage…simpler changes than with LOX tanks.

I am confused, Sirangelo hasn't confirmed the switch of the propulsion system:
http://www.americaspace.com/?p=66192

Quote
Have you changed the Dream Chaser’s propulsion system from a hybrid solid/liquid system to an all liquid system as some have claimed recently, and readers asked in Part 1?

“We have not announced a change in propulsion systems and that was not a quote from us.”

“It was likely meant to refer to our acquisition of Orbitec as we now have an expanded base of propulsion solutions and are exploring their use for future Dream Chaser variants.”

Atlas V 412 is also officially confirmed (so it's no longer a 402):

Quote
What are the on orbit flight goals for Dream Chaser’s 2016 mission? It’s likely to be at least several orbits and perhaps even days long.

“For the Nov. 2016 flight it will be a full orbital flight. We are launching using a full Atlas V in the same flight configuration as we would use to go to the space station with. We are flying on an Atlas V 412. The first stage has one strap on solid. We are lighter [compared to CST-100] and don’t need a second solid. The second stage uses a dual engine Centaur.”

“We will do an orbital flight with a series of checkouts of important elements of the vehicle and then we are flying it back home.”

Mark Sirangelo stated following from America space interview.

 “We have not announced a change in propulsion systems and that was not a quote from us.”

“It was likely meant to refer to our acquisition of Orbitec as we now have an expanded base of propulsion solutions and are exploring their use for future Dream Chaser variants.”

“There is no schedule change related to engines.”

So the DC is staying with it's existing hybrid engines for the first orbital version at least.

He does not deny an engine change. He simply states they haven't announced it and he claims there's no schedule change related to engines.

 It's surprising to me that DC is lighter than CST-100.

Sierra Nevada Corporation Develops Design
for Stratolaunch Air Launch System for Low Earth Orbit

SPARKS, Nev., Sept. 30, 2014 – Sierra Nevada Corporation (SNC) today announced a design for an integrated system for human spaceflight that can be launched to low Earth orbit (LEO) using Stratolaunch System’s air launch architecture and a scale version of SNC’s Dream Chaser® spacecraft.

The Dream Chaser is a reusable, lifting-body spacecraft capable of crewed or autonomous flight. Dream Chaser is the only lifting-body spacecraft capable of a runway landing, anywhere in the world. Stratolaunch Systems is a Paul G. Allen project dedicated to developing an air-launch system that will revolutionize space transportation by providing orbital access to space at lower costs, with greater safety and more flexibility.

As designed, the Dream Chaser-Stratolauncher human spaceflight system can carry a crew of three astronauts to LEO destinations. This versatile system can also be tailored for un-crewed space missions, including science missions, light cargo transportation or suborbital point-to-point transportation. The scaled crewed spacecraft design is based on SNC’s full-scale Dream Chaser vehicle which, for the past four years, has undergone development and flight tests as part of NASA’s Commercial Crew Program.

Chuck Beames, president, Vulcan Aerospace Corp and executive director for Stratolaunch Systems said, “Combining a scaled version of SNC’s Dream Chaser with the Stratolaunch air launch system could provide a highly responsive capability with the potential to reach a variety of LEO destinations and return astronauts or payloads to a U.S. runway within 24 hours.”

“This relationship would expand our portfolio to include the highly flexible Stratolaunch system for launching reusable crewed or uncrewed spacecraft, or for rapid satellite constellation deployment,” said Mark Sirangelo, corporate vice president of SNC’s Space Systems.

In addition to supporting development of human spaceflight capability, SNC studied satellite launch options and mechanisms, as well as point-to-point transportation options using the Stratolaunch launch system with a Dream Chaser spacecraft derivative. The Stratolaunch system is uniquely designed to allow for maximum operational flexibility and payload delivery from several possible operational sites, while minimizing mission constraints such as range availability and weather.

SNC and Stratolaunch Systems will present more detailed information on Dream Chaser-Stratolauncher at the 65th International Astronautical Congress in Toronto, Canada, on October 1, 2014 at 9:45 am ET in Room 701B.

Sierra Nevada Corporation to Present Progress on
Evaluating Dream Chaser® Landing at Public Use Airports

SPARKS, Nev. (Nov. 5, 2014) – Sierra Nevada Corporation’s (SNC) Space Systems and partner organization RS&H, Inc., presented findings regarding the challenges and opportunities of landing the Dream Chaser® reusable spacecraft at public-use airports during the Space Traffic Management Conference at the Embry-Riddle Aeronautical University (ERAU) Daytona Beach, Florida, campus today.

The Dream Chaser is a unique lifting-body commercial orbital vehicle designed for crewed or uncrewed missions in low-Earth orbit (LEO) that is capable of a runway landing nearly anywhere in the world. The SNC and RS&H, Inc. team has been analyzing the applicable standards and unique requirements that must be addressed to receive approval for Dream Chaser to land either at a spaceport or commercial airport.

Today’s presentation summarized the capabilities of the Dream Chaser spacecraft and described present efforts to land at commercial airports with minimal impact to existing operations. Presenters discussed next-steps including how SNC plans to ensure that the Dream Chaser meets safety and environmental requirements, as well as operates within, or exceeds, existing and future procedures and policies.

SNC’s Dream Chaser is a multi-mission space utility vehicle. It is the only reusable, lifting-body spacecraft with commercial runway landing capability, all non-toxic propellants, no unique landing or navigation aids and responsive mission, ground, and transportation operations. The space system is on the forefront of the commercial spaceflight industry, offering safe, affordable, and reliable crew and cargo transportation to LEO space destinations.

With ethane one would have pretty good pressure in chamber for self-pressurizing motor. With propane one needs something to rise the pressure with.

SNC Tests Dream Chaser Propulsion System
December 2, 2014

Sierra Nevada Corporation, one of NASA’s Commercial Crew Program partners through the agency’s Commercial Crew Integrated Capability (CCiCap) initiative, recently performed incremental tests of its reaction control system, which will help maneuver its Dream Chaser spacecraft in space. The company’s Milestone 15a built on SNC’s previous propulsion system development efforts by implementing a compact prototype thruster operating in a vacuum chamber to simulate an on-orbit environment.

I'm skeptical of SNC in a lot of ways.  But it sounds like SNC has a valid basis for its protest.  If NASA doesn't list schedule risk as a high priority in their solicitation of bids, they can't really use that to override the much lower cost of SNC's bid.

Maybe NASA should have listed schedule risk as important.  But they didn't.  It seems to me SNC is right that it's wrong for that to trump much lower cost.

I sure hope they don't have to re-bid the whole contract if the protest is successful.  That would be a disaster for U.S. human spaceflight.  I wonder if it's possible for them to simply switch the award to SNC and cancel the Boeing contract if SNC wins the protest.

Sure they can. Not being listed as a high priority doesn't mean it's not a factor. When schedule risk gets to the point of little to no chance of happening on time, it can be disqualifying by itself. The bid has to be credible and this contract can't abide a three year slip. Everybody but Boeing wanted Dreamchaser, but dropping the engine pretty much sealed it.
Title: Re: SNC Dream Chaser UPDATE Thread
Post by: rokan2003 on 12/28/2014 01:29 PM
It's not as simple as that.  Obviously, it's a matter of degrees, and that's what the ruling will turn on. But if the bid documents made clear that schedule was a big priority, and that slips, which are common place in this industry, couldn't be tolerated, then the bidders could have put measures in place in their bids to mitigate against such slips. Clearly SNC didn't understand this to be so. If they are right and the bid documents didn't make it clear that schedule would play a major role in the decision, it would be unfair to make the award based on the ability to deliver on schedule. Take the engine decision: if SNC understood they'd have to deliver on schedule or else, they might not have made the decision to move away from their initial plan. Of course, we have to remember that these are all just allegations by SNC and perhaps schedule was not given too much weight in the decision. We'll know soon enough.

Post by: baldusi on 12/28/2014 01:56 PM
Schedule was the leading factor. The discussion is if the Mission Suitability was taken as a set of independent variables, or one of such variables was almost binary (i.e. they can do it by 2017 or they can't).

Schedule was the leading factor.
We know this isn't true. It's public information that price was weighted the same as all the other metrics combined.

... Maybe NASA should have listed schedule risk as important.  But they didn't.  It seems to me SNC is right that it's wrong for that to trump much lower cost.

Risk (schedule or otherwise) is an inherent part of the evaluation and results in a confidence level; it is not something that stands apart with the arguable exception of the past performance evaluation.  And what baldusi said.
Quote from: CCtCap RFP
C.1 SPECIFICATION/STATEMENT OF WORK
The purpose of the Commercial Crew Program (CCP) is to facilitate the development of a U.S. commercial crew space transportation capability with the goal of achieving safe, reliable and cost effective access to and from low Earth orbit (LEO) including the International Space Station (ISS) no later than 2017.
M.2.I. Technical, Crew Safety and Mission Assurance Subfactor
The Offeror’s technical approach to obtain NASA certification of a Crew Transportation System (CTS) with a goal of NLT 2017; to plan and execute Post Certification Missions; to perform ISS integration; and to incorporate safety and risk mitigation in all CCtCap activities will be evaluated for compliance with contract requirements.
Similar is repeated at the beginning of several other key sections of the RFP; 2017 is obviously an important date, and is hard to miss.

... It's public information that price was weighted the same as all the other metrics combined.
Nit: not "all other metrics combined".  Also, "weighted the same" suggests numerical or comparable scoring across all evaluation factors, which is not the case (only Mission Suitability is numerically scored).  The relationship between price, mission suitability and past performance is adjectively (not numerically) defined with consequent ambiguity.

For more information on source selection and evaluation, see NASA FAR Supplement NFS-1815 (http://www.hq.nasa.gov/office/procurement/regs/1815.htm)

In any case, I believe we have had these discussion previously in the other thread Dream Chaser shows her fight - SNC protest CCtCap decision (http://forum.nasaspaceflight.com/index.php?topic=35728.0).

Schedule risk is a manifestation of technical risk.  It is EXTREMELY unlikely that SNC will win the protest.  If that did happen you likely would have the tanker contrac fight again if they tried to just switch it.  And remember who won that in the end.

Maybe it's just me, but I find it very annoying when people talk about things that are under development as if they already exist.  This press release talks about Dream Chaser in the present tense as if it already existed.  "SNC’s Dream Chaser is a multi-mission-capable space utility vehicle that is able to flexibly operate as an independent science platform, ...".  If you didn't know anything about Dream Chaser and just read this press release, you'd think it was flying today.  There's not a word about the fact that it's under development, let alone that there's uncertainty about whether it's going to get the huge amount of funding it would take to reach operational status.  They could at the very least use the future tense.

That near-term focus on alternative launch options means Stratolaunch is deferring work on a crewed vehicle that would launch on the Orbital ATK booster. At the International Astronautic Congress in Toronto in October, Stratolaunch and Sierra Nevada Corp. announced they were studying the development of a 75-percent-scale version of Sierra Nevada’s Dream Chaser spacecraft.

“What we’ve decided to do is kind of take a pause on further development of that,” he said, as Stratolaunch examines alternative launch options. Beames said that human spaceflight remained a long-term goal of the company, and that it still considered Dream Chaser the best spacecraft option. “Once those plans are solid going forward, we will re-engage with Sierra Nevada specifically on the modified Dream Chaser,” he said.

Landing like an aircraft has its advantages, but I would strongly disagree with calling it the safest.  That style of reentry and landing requires a much finer degree of control and has more failure modes than other methods.

Parachutes+water landings will stay in the lead safety-wise for the foreseeable future, but if you wish to consider other EDL methods (because you value the advantages they bring sufficiently to trade a little safety) it's a really unclear to me what's the next best method.

I degree on the grounds that statistics says otherwise.
The avionics on a space plane are probably more reliable then everything else in a space transportation system as they're more or less the same kind of technology millions of people trust their lives with every day when they fly on a commercial jet.

The shuttle's two LOC events were stack interaction related vs a failure of the landing systems.
It had a fragile TPS ,no LAS, and was in the debris stream of the launch stack.
Other then the two accidents the shuttle has not caused any injuries esp during landing.

Since Dream Chaser sits on top of it's LV and has a LAS the type of LOC events that happened on STS 51L would not have been a loss of crew event and the failure that happened on STS 107 would be impossible as there are no tanks ahead of the vehicle to shed debris.

I think DC on Atlas V could in fact be one of the safest spacecraft designed so far.
When it lands it's at an airport vs in the middle of the ocean,or the wilderness.
One of these is a better situation to be in then the other two esp if the crew has been deconditioned from a long flight or a crew member needs medical attention.

CST-100 will land at somewhere like Edwards AFB, which is hardly wilderness.  Dragon will eventually transition to landing sites like the one at Vandenberg.  The lower G-forces of DC for long-term returnees will only be of benefit if the person is riding in a seat moved to the supine position, as was done on the Orbiter's mid-deck.  Have we seen any renderings showing that in the small DC cabin?  Both capsules have equipment to handle a degraded landing, such as three chutes or landing rockets backed up by chutes, plus water-landing capability, if needed.

There have not been enough space flights to make any sort of judgment with any real statistical significance.  Even at a fairly low confidence level, the margin of error with respect to the number of samples available is quite large.

Instead, you need to look at the designs themselves.  Capsules are more able to be made passively stable, which means they can still survive a reentry even with complete loss of attitude control -- see, e.g., the Soyuz ballistic reentry profile.  Even with the shuttle, the winged design meant that positive control had to be maintained at all times, as the vehicle could not withstand the aerodynamic forces if its angle of attack or sideslip angle went beyond a specific envelope.
Title: Re: SNC Dream Chaser UPDATE Thread
Post by: adrianwyard on 04/22/2015 05:00 PM
That reminds me that we rarely acknowledge that the DC shape should be passively stable; the forces on those canted fins placing the center of lift above the center of mass. I suspect (but don't know) that DC could be even more stable than a capsule were it loaded with heavy cargo.

"Sierra Nevada Dream Chaser could make Huntsville the first commercial landing site for space craft"

http://www.al.com/news/index.ssf/2015/06/sierra_nevada_announcement.html

Local leaders this morning announced Huntsville will study feasibility of landing the Sierra Nevada Corporation's Dream Chaser spacecraft at Huntsville International Airport.

Depending on the results of the study, Huntsville could become the first commercial airport landing a space craft, Mayor Tommy Battle said at the announcement Monday morning.

The study will take about six months, and landings could begin as early as 2018 when Dream Chaser is expected to begin space flight. The spacecraft will launch to space on an Atlas rocket built by United Launch Alliance of Decatur.

"The Dream Chaser spacecraft is proposed by SNC in the current NASA competition to supply cargo to the International Space Station," a media advisory from the Chamber said last week. "SNC also plans to operate the vehicle on other missions, tailored to a variety of U.S. and International Customers."

Dream Chaser Prepares for Flight
Posted on June 19, 2015 at 2:42 pm by commercial-crew-program.

Sierra Nevada Corporation’s Dream Chaser engineering test article is being prepped for its second free-flight test at NASA’s Armstrong Flight Research Center in California later this year. The flight test is a milestone under NASA’s Commercial Crew Integrated Capability (CCiCap) agreement with SNC.  The wings, windows and landing gear are installed. The Dream Chaser’s the nose skid will have thermal protection system tiles on the vehicle, manufactured at Kennedy Space Center’s Thermal Protection System Facility, for the flight test. The performance of the tiles will be assessed following the touch down on the runway.

SNC will share their thermal protection system work and a status of the Dream Chaser spacecraft to media and social media attending CRS-7 activities at Kennedy Space Center next week.

Tile Shop Prepping Heat Shields for Future Flights
Steven Siceloff, KSC June 26, 2015

Heat shield tiles are getting stronger to make the next generation of American spacecraft safer as they experience searing heat and plasma on their way back into Earth’s atmosphere for landing.

[…]

Jacobs Technology engineers are producing test samples that will be used to protect the Dream Chaser spacecraft under development by Sierra Nevada Corporation (SNC) in partnership with the agency’s Commercial Crew Program. The facility is the same workshop that produced space shuttle heat shield tiles at NASA’s Kennedy Space Center for more than 30 years.

SNC continues to advance its development of the reusable Dream Chaser spacecraft that launches vertically atop a United Launch Alliance Atlas V rocket and returns to Earth for a runway landing. Like the shuttle, the Dream Chaser will use several kinds of protective materials on the outside of the spacecraft to form a protective barrier. Tiles made from improved silica-based blocks will make up most of the belly and upper portion of the heat shield, while a new material developed at NASA’s Ames Research Center called “TUFROC” will cover the nose and leading edges. Those are the surfaces that must resist and mitigate the highest temperatures the spacecraft experiences from the friction of re-entering Earth’s atmosphere. Another factor that makes the tiles desirable for a heat shield: they are mostly air. As a result, the tiles are extremely lightweight, a vital factor for spacecraft design in which weight is the primary driver of launch costs.

At first glance, the white blocks with a Styrofoam texture look no different than the thousands of blocks made for the space shuttle heat shields before being coated with a black ceramic material. But these new blocks incorporate advanced materials, making them stronger while maintaining the capability to prevent searing plasma from jeopardizing a spacecraft or its crew during the hazardous phase of a mission as the crew returns from orbit through Earth’s atmosphere on the way to a landing.

The nose skid of the Dream Chaser currently is outfitted with thermal protection system tiles to assess performance in preparation for a free-flight test of the spacecraft at the agency’s Armstrong Flight Research Center targeted for later this year.

Presser:

Sierra Nevada Corporation Announces New
Dream Chaser® Spacecraft – Designated Landing Site Program

SPARKS, Nev. (September 10, 2015) – Sierra Nevada Corporation’s (SNC) Space Systems announces the launch of a new program, the Dream Chaser®-Preferred Landing Site Program, in which SNC will work with spaceports and commercial airports to become a designated landing site for the Dream Chaser spacecraft.

“The number of applicants requesting spaceport licenses both domestically and internationally has increased dramatically over the past 24 months,” said John Roth, vice president of business development and strategy for SNC’s Space Systems. “SNC’s Dream Chaser spacecraft is the only commercial space vehicle that is capable not only of a runway landing, but landing on runways that already support commercial aircraft. SNC has created this program based on the tremendous interest we have received to date from spaceports and airports around the world that want to host Dream Chaser landings as a stimulant to their local economies.”

Through the Dream Chaser-Preferred Landing Site Program, SNC is offering three different levels of designation, with the highest level culminating in the Federal Aviation Administration (FAA) issuing a re-entry license to SNC for the designated spaceport or airport.  This program was created based on similar work currently being done with Ellington Spaceport in Houston, Texas and the Huntsville International Airport Authority (HIA) in Huntsville, Alabama.

Recently, the FAA granted a launch site license to the Houston Airport System (HAS), allowing the launch of reusable vehicles from Houston.  HAS was only the tenth location to be granted such a license. SNC has worked with HAS for over a year to aid in the submittal of their license and to assess the feasibility of landing Dream Chaser in Houston, home of NASA’s Johnson Space Center.

As announced in June at the Paris Air Show, SNC is also working with the City of Huntsville to assess the feasibility of landing the Dream Chaser spacecraft at the Huntsville International Airport, a public-use airport. Huntsville plays a significant role in the national and global space community.

“Dream Chaser is poised to lead the commercial space industry in reusable, low-Earth orbital flight,” said Mark N. Sirangelo, corporate vice president of SNC’s Space Systems. “The benefits of multiple landing sites would be significant to both the landing site community and to the Dream Chaser network of domestic and international partners. With each Preferred Landing Site designation, comes a greater opportunity to make commercial space an accessible reality.”

SNC’s Dream Chaser spacecraft requires only a 10,000 feet or longer runway and does not have any onboard toxic consumables, including propellants. Therefore, the vehicle has very limited environmental impact and affords immediate post-landing access to the spacecraft.

(October 7, 2015) – In anticipation of a second phase of flight testing, Sierra Nevada Corporation’s (SNC) Space Systems has announced significant updates to two Dream Chaser®  spacecraft currently in development. The spacecraft are the atmospheric engineering test article (ETA) and the advanced composite orbital vehicle, which when tested will undergo a suborbital and orbital flight regimen, respectively. SNC’s Mark Sirangelo provided a program update at the International Symposium for Commercial and Personal Spaceflight (ISPCS) in New Mexico.

“The SNC team is readying the ETA in order to begin the second phase of atmospheric flight testing early next year and our strategic partner, Lockheed Martin, is leveraging best practices in tooling and composites to manufacture the first orbital Dream Chaser spacecraft,” said Mark. N. Sirangelo, corporate vice president, SNC’s Space Systems. “Both efforts have been ongoing simultaneously and we are very pleased with the progress to date.”

Since flight test phase one, in which SNC’s Dream Chaser ETA successfully returned trajectory data of the flight profile, SNC has made significant structural and systems improvements to the ETA including the composite wings and aeroshells. SNC also invested heavily in maturing the spacecraft orbital avionics, guidance navigation and control, the flight software, and employed a number of new processes, all of which will be used on the orbital vehicle as well. Finally, the advanced orbital Thermal Protection System (TPS), announced in June, was installed on the ETA skid in order to do advanced testing of the actual orbital TPS in this important area.

“The Dream Chaser ETA is currently scheduled to arrive at Armstrong Flight Research Center in early 2016 in order to begin the second phase of atmospheric flight test.”

In parallel to the ETA upgrade, SNC has made significant progress on the build of the first Dream Chaser orbital vehicle manufactured by Lockheed Martin. Lockheed Martin is leveraging best-practices in composite manufacturing from the Skunk Works®, its advanced development programs division, as well as its extensive experience in manufacturing and assembly from the F-35 Lightning II.

Lockheed Martin recently completed the Dream Chaser orbital cabin assembly, marking a significant milestone in the construction of this vehicle.  This assembly is the largest high-temperature unitized structure ever fabricated at U.S. Air Force Plant 4. The assembly utilized three-dimensional woven joints, to integrate internal frames with external carbon skins in a single co-bond operation, meaning nearly all fasteners on this critical cabin assembly are eliminated. This state-of –the-art approach to design and manufacturing is a highly efficient and affordable design solution.

“Upon completion, the Dream Chaser orbital vehicle will be the most advanced composite structure ever built. We look forward to Dream Chaser becoming the world leader in this area and to its first orbital flight,” said Sirangelo.

SNC’s Dream Chaser spacecraft is the only reusable, lifting-body, multi-mission-capable vehicle with a commercial runway landing capability - anywhere in the world. The Dream Chaser is a safe, affordable, flexible and reliable system capable of crewed and uncrewed transportation services to low-Earth orbit destinations such as the International Space Station. SNC has designed the Dream Chaser Cargo System as a solution for NASA’s commercial transportation services needs under the Cargo Resupply Services 2 contract and for other fully autonomous orbital missions.

Some bits in the news about allowing Dream Chaser to land at Huntsville. Talk about whether they'd actually land at an airport with scheduled commercial service aside there was some interesting info as to what they're assessing.

They did dynamic testing on the runway to simulate the skid plate and the airport described any negative effects as "negligible." The airport, FAA, and regional control centers would have to coordinate but it was deemed as feasible. Further testing is required and a commercial landing permit would be required from FAA.

From what I understand by reading the article, the ESA invests in SNC doing the design and development work on the IBDM.  SNC cost shares building the first IBDM and can use in on the 1st cargo DC flight.  At the end of the development, ESA owns the intellectual property of the IBDM and will earn revenue each time SNC builds another IBDM and ESA can choose to build their own IBDM if needed.  Since we are not privy to the contract details, the exact terms may be different than what I describe.

Well I actually thought this money will for a large part go to Qinetiq, a European (United Kingdom-Belgium) company that has been working on the IBDM for 10 years already, they have built prototypes (I've seen one recently but neglected to take a picture). For ESA this is more like a way to have an 'in' into this project, ISTM. Also ESA cannot exploit technology for 'revenue', they are supposed to develop risky stuff and then let industry take over.

Anyways I talked to a pm at that company and they were all very disappointed to hear the 5 November delay of announcement and they seemed pretty happy with the announcement that SNC was in on the game.

Meanwhile I'm happy for the space industry in Belgium, one I hope to find a job in next year.

The petals are there to correct rotation mis-alignment, and to help guide the two adapters together. Hopefully most dockings should be precise enough to not need it, though.

There are three petals on the docking port, and three on the approaching spacecraft - but they are arranged 180 degrees from one to the other. They fit together like interlocking fingers.

The current standard for docking systems is the International Docking System Standard (Revision D) which can be read here:

http://www.internationaldockingstandard.com/download/IDSS_IDD_Revision_D_043015.pdf

Any docking system designed to be IDSS compliant should be capable of docking with any other system that is also IDSS compliant.

A full-scale engineering test article of Sierra Nevada Corporation’s Dream Chaser spacecraft is nearing completion leading to a second round of atmospheric evaluations at NASA’s Armstrong Flight Research Center in Edwards, California. The flight testing, which calls for the Dream Chaser to be released high over California’s Rogers Dry Lakebed and glide to a safe landing, will build upon an earlier free-flight test milestone that returned valuable data for the design team.  Photo credit: Sierra Nevada Corporation

KENNEDY SPACE CENTER, Fla — The Thermal Protection System Facility Annex or “TPSF” served NASA’s Space Shuttle Program during the iconic spacecrafts’ 30-years of service. It is now being used by one of the newest entrants under the second phase of the agency’s Commercial Resupply Services contract – Sierra Nevada Corporation.

In terms of CRS, the facility has been used on Sierra Nevada Corporation’s (SNC) Dream Chaser shuttle. One of the original versions of the spacecraft were planned for use on NASA’s Commercial Crew Program. However, when it came time for the selection of the Commercial Crew transportation Capability (CCtCap) down select (in September of 2014) – NASA opted to go with the crewed version of SpaceX’s Dragon spacecraft and Boeing’s CST-100 Starliner.

There is a bit of an update in this recent article:

http://magazine.onlineamd.com/article/march-2016-/dream-chaser-to-supply-cargo-to-the-international-space-station.aspx

Quote
He [Lindsey] adds that SNC is working collaboratively with its wholly-owned subsidiary, Orbital Technologies Corp. (ORBITEC), to mature, advance, and refine all of the non-toxic systems being used for the reaction control system (RCS) and environmental control and life support system (ECLSS) on the Dream Chaser spacecraft. [...]

Another former NASA astronaut, Lee “Bru” Archambault, who flew two shuttle missions – one as spacecraft commander – will serve as the Dream Chaser director of flight operations. [...]

Sirangelo says the Dream Chaser Cargo System is designed to be operated autonomously, with ground monitoring. “In the event of degraded systems, damage, or other issues, we do have ground control operations that exist as a back-up mode. The uncrewed Dream Chaser spacecraft does not require any unique navigational aids, remote systems, or special ground support equipment, beyond GPS signals, and standard navigational aids and systems.” [...]

Next comes building and assembling two orbital flight vehicles. Lockheed Martin in Colorado already has begun building the structure for the first orbital vehicle, and SNC will build cargo modules as customer demand requires.

Perhaps for non-NASA-missions. But NASA said that they wanted their samples in Florida at the CRS-2 press conference.

See also this recent interview with John Roth of SNC who confirms that the SLF will be the landing site for CRS2:

Quote
What are the plans for launch and landing sites? Will the Kennedy Space Center play a major role?

The contract right now for the cargo missions is based on launches out of Kennedy and landing at the shuttle landing site facility at Kennedy. Obviously we’d have an option—if they wanted—to discuss with us launching and landing from somewhere else but that’s our baseline concept in the CRS2 proposal. We have been working with a lot of different airports and spaceports both in the US and internationally who are interested in being able to land Dream Chaser at their facilities. We have had a number of discussions with those airports and spaceports. We have a few that are public like Houston and Alabama and a few others that we have been working with that have elected not to go public yet.

We are moving forward towards plans to look at eventual FAA licensing for landing Dream Chaser at other places than Kennedy. That right now is not part of our cargo contract.

I have to admit that Dream Chase looks to be the most exciting of all cargo or crew vehicles. I'll reconsider that when Dragon V2 starts doing powered landings.

I could not find information on the SNC website or ULA, but according to the video , it looks like they will use the Atlas V 552?   I saw two engines on the upper stage, large fairing, as well as the fairing being jettisoned before MECO. ( 48s into the clip)   Is the 552 configuration at the edge of its limits to lift Dream Chaser plus cargo?   Early jettison of the fairing makes sense, as Dream Chaser should be plenty robust for some minimal atmospheric loading during ascent.

I also wonder if Dream Chaser missions to ISS are now possible with just F9 FT vs. FH?   SNC does mention missions of Dream Chaser using FH, but that is somewhat dated to the crewed proposal.  F9 FT to LEO with Dream Chaser could be pretty low cost.

This discussion should be moved to the DC discussion thread. But to answer your questions, SNC hasn't stated it officially but most think that it is indeed an Atlas V 552 in the video.

The fairing of the F9 might be too small for both DC and its trailer. Presumably, FH has an option for a taller fairing. There was a discussion on both of these points in the discussion thread.

On March 31, 2016 Sierra Nevada Corporation participated in a press briefing hosted by the Chamber of Commerce of Huntsville/Madison County regarding the feasibility of landing SNC’s Dream Chaser spacecraft at Huntsville International Airport. Following that briefing it was reported that Huntsville is the only community that SNC is considering to land its SNC’s Dream Chaser spacecraft. Huntsville International Airport was the first commercial airport to initiate a landing site study and licensing effort for Dream Chaser and SNC is currently working with the Huntsville community regarding potential future commercial missions. However, all NASA Commercial Resupply Services 2 contracted missions will land at the Shuttle Landing Facility at Kennedy Space Center.

This part of the article from Satellite Today is interesting:

Quote
Regarding influences for future SNC satellites, Roth said the company’s acquisition of Orbital Technologies Corporation (Orbitec) in 2014 could influence new propulsion systems. One of Orbitec’s specialties is upper stage engines and in‐space propulsion systems. SNC acquired Orbitec because the company was heavily involved in the development of Dream Chaser, SNC’s multipurpose spacecraft that resembles a “mini‐Space Shuttle.” SNC employees from the company’s satellite side collaborate with and support employees working on Dream Chaser. Roth anticipates green propellant systems will gain popularity in coming years, as well as electric propulsion. He said SNC has designs for incorporating electric propulsion into Non‐Geostationary (NGSO) small satellites as well as the company’s small GEO product.

https://www.bostonglobe.com/business/2016/04/28/draper-another-drive-into-space/ruYyV9cyo9lQT7ufBOQS5L/story.html

Quote
Dream Chaser can be launched atop a commercial space rocket. It’s designed for totally automated flight, with Draper’s software guiding it all the way. Draper already makes the guidance software for another space station resupply vessel, the unmanned Cygnus capsules. [...]

At Draper in Cambridge, a flight simulator is already running make-believe landings on a virtual runway. Tuohy said visitors who have tried to steer the simulated spacecraft have almost always crashed; the computer gets it right every time. [...]

The next Dream Chaser drop test is set for December. There’s still a vast amount of work ahead before the first space launch in 2019. And unlike other Draper space efforts, Dream Chaser is a commercial enterprise, and NASA only pays for performance.

FOR IMMEDIATE RELEASE

Sierra Nevada Corporation Completes First Dream Chaser® Cargo Service Milestone under NASA CRS2 Contract

SPARKS, Nev. (July 11, 2016) – Sierra Nevada Corporation (SNC) is pleased to announce the successful completion of ISS Integration Certification Milestone 1 for the Dream Chaser Cargo System under NASA’s Commercial Resupply Services 2 (CRS2) contract. Under this milestone, NASA approved SNC’s complete program implementation plan for the design, development, test and evaluation of the Dream Chaser Cargo System. This includes plans and processes for meeting technical performance and CRS2 integration schedules associated with execution of docking and berthing missions to the International Space Station (ISS). Details included supplier plans, integration schedules, organizational structure and status of program risks and risk mitigations. Under the CRS2 contract, Dream Chaser will provide a minimum of six cargo delivery services to and from the ISS between 2019 and 2024.

More Than a Milestone
“The accelerated completion of the first milestone under the CRS2 contract award marks significant progress for SNC and the Dream Chaser program”, said Mark N. Sirangelo, corporate vice president of SNC’s Space Systems business area. “We are thankful for the support we’ve received from NASA. The prompt completion of this essential program milestone is a big step in bringing us closer to returning a winged, runway-landing vehicle to space. This momentum will carry us with confidence in developing a reliable and affordable solution for ISS cargo delivery, return and disposal.”

In addition to SNC internal program integration, the milestone review covers the strategic plan for the involvement of external entities including international agreements and plans for obtaining necessary licenses from U.S. agencies, including the Federal Communications Commission and Federal Aviation Administration.

Flight Testing Continues
In parallel with the continued execution of CRS2 milestones, SNC plans to resume the next phase of flight testing for Dream Chaser later this year. This vehicle was originally developed and tested in partnership with NASA’s Commercial Crew Program through Space Act Agreements (SAA). It was previously flown at NASA’s Armstrong Flight Research Center and is being prepared for its second flight test through the SAA. It has been significantly upgraded in multiple areas to allow for testing to advance and verify critical systems which will also be used in the next generation vehicle currently under development for the forthcoming NASA ISS cargo resupply missions.

Sierra Nevada Corporation Passes Second Milestone – Dream Chaser® Spacecraft on Track to Supply Cargo to ISS

SPARKS, Nev. (June 25, 2016) – Sierra Nevada Corporation (SNC) has passed the second Integration Certification Milestone under NASA’s Commercial Resupply Services 2 (CRS-2) contract. NASA assessed and fully approved SNC’s detailed approach for getting the Dream Chaser Cargo System to the International Space Station (ISS). SNC’s approved strategy demonstrates a thorough understanding of design requirements and available resources on both a system and subsystem level.  Dream Chaser will provide a minimum of six cargo delivery missions to and from the ISS between 2019 and 2024.  The first milestone was passed several weeks ago and outlined technical, logistic and schedule procedures for the program.

“Successful completion of the second Integration Certification Milestone within six weeks of the first major milestone demonstrates that the Dream Chaser team is moving at full-speed to meet NASA’s cargo delivery needs,” said Steve Lindsey, senior director of programs for SNC’s Space Systems business area and Dream Chaser co-program manager. “We very much appreciate NASA’s help and support through this milestone and those to follow. Our collective SNC/NASA team is confident in our design and strategy for the future and look forward to completing the work necessary to bring our unique cargo services solution to the ISS as rapidly as possible.”

Milestone 2 Key Components
Completion of Milestone 2 means NASA and SNC collectively agree on the certification criteria used to confirm Dream Chaser designs meet CRS-2 mission requirements.  These qualification and verification plans will be utilized during future integrated design and test milestones to validate Dream Chaser Cargo System capabilities.

Dream Chaser Flight Tests Will Support CRS2 Progress
The current flight vehicle has been upgraded with several cargo system design components to support multiple test objectives - verifying the spacecraft’s performance during final approach and landing, directly supporting the CRS-2 Certification Plan approved during Milestone 2.  This will ultimately accelerate development of the first orbital mission and increase confidence through flight-tested systems. The vehicle was originally developed and tested in partnership with NASA’s Commercial Crew Program, which included a full-test campaign at NASA’s Armstrong Flight Research Center leading up to the October 2013 approach and landing test.

Look at Dream Chaser all repaired! :)

Dream Chaser® Spacecraft to Begin Phase Two Flight Testing

SPARKS, Nev. (July 28, 2016) – Sierra Nevada Corporation’s (SNC) Dream Chaser full-scale, flight test vehicle is ready for transportation to NASA’s Armstrong Flight Research Center (AFRC) in California where Phase Two flight tests will be conducted in coordination with Edwards Air Force Base (AFB). Dream Chaser program upgrades and initial hardware testing were completed at the Louisville, Colorado spacecraft assembly facility, and within the next several weeks the same Dream Chaser vehicle that conducted Phase One flight testing will arrive at NASA’s AFRC. Upon arrival, SNC will begin a series of pre-flight ground evaluations to verify and validate the vehicle’s system and subsystem designs. After successful completion of all ground testing, Dream Chaser will begin its Phase Two free-flight testing. These activities are being conducted through a Space Act Agreement with NASA’s Commercial Crew Program (CCP).

“Dream Chaser continues to make strong progress toward orbital flight,” said Mark N. Sirangelo, corporate vice president of SNC’s Space Systems business area. “In addition to Phase Two flight testing, our on-time completion of the first two milestones under NASA’s Commercial Resupply Services 2 (CRS-2) contract in the last two months positions us well to be on-schedule for orbital operational flight. We are very grateful for all the support we have received from NASA and the U.S. Air Force, and are excited to continue the legacy of historic flight testing that is the hallmark of NASA AFRC and Edwards AFB.”

What Are We Testing?
The vehicle will undergo a series of tests building on those performed in Phase One, including tow-tests, pre-flight tests and ending with free-flight testing. SNC is also performing additional critical tests to validate the Dream Chaser’s orbital flight software and calculate the spacecraft's handling and performance characteristics. Along with other pre-flight and post-flight evaluations, this data will be used to confirm Dream Chaser’s subsonic aerodynamic properties as well as flight software and control system performance requirements.

“These tests are significant for us in multiple ways; building on our previous flight test, completing a significant milestone under our CCP agreement, as well as gathering crucial data that will help complete the design of the vehicle being built for our CRS-2 contract,” said Sirangelo.

CCP Testing Supports CRS-2 Development
The Phase Two flight test efforts will be highly supportive of, and executed in parallel with continued work being done by SNC under the NASA CRS-2 program. The Dream Chaser test vehicle has been upgraded to include several hardware and software components being integrated into the Dream Chaser Cargo System design for the CRS-2 program, allowing for actual flight testing of the new components. The flight tests will act as a bridge between previous work with CCP and the next-generation vehicle currently under development for the forthcoming International Space Station cargo resupply missions.

Some screen captures.

22 launches of something we built. Helped build Cygnus. Do the berthing adaptors. Protected Juno mission from radiation. 20 millions rads coming into Jupiter. Dreamchaser can land on any airport that can a B737 or A320. FAA certified Houston and Huntsville airports. 12 other airports working to get certified. By folding wings can return in C-5 cargo plane.

For Dreamchaser carho took out all things that are not needed for human spaceflight. Took out ECLSS and abort motors. 5500 kg cargo capacity. Cargo module burns up. 15 to 20 times reusability. None of this works if we don't do the primary mission well. Looking at what else we can do. That's a pretty interesting list. Provide a vehicle, rocket and training. Integration experience. Come home at  1.6g. Leave home at breakfast and be home at dinner. 6 to 10 hours. Created full interior mockup of vehicle in a module fashion. Be able to quickly change modules. Can carry up to 1500 kg of exterior payload in 500 kg bays.

Some captures from the presentation.

NASA. We don't think we could have lost another one. We have contingency supplies. For CRS-2 its about the same. A little more oversight for reliability and launching on time. A lot of complaints of the delays which is a big cost expense for the payloads. Station was prepared. Commercial payloads hurt more. Redundancy in CRS2. We did not overbuy. Capability to add missions if we need to. Launch on need capability. Bring up another vehicle quickly. Right now go with the missions we have if everything went according to plan. Have an ability to surge.

In this presentation, it was confirmed that the first missions of cargo DC will berth (not dock). However, Angela Hart from NASA said "at least in the initial vehicles" which implies that it could change later on (at 5m40s of the video).

UN News: UNOOSA is looking to launch the first UN mission to outer space. Tell us about that.

Simonetta Di Pippo:
We have started to understand that access to space is really important for developing countries to be part of this space community and to get more and more benefits from being part of this process.

We are working with the Sierra Nevada Corporation, which has developed the Dream Chaser vehicle. This is quite an interesting spaceship because it goes up as a normal space object and comes back as a normal plane so it can land on a normal landing strip. What we are trying to do now is to put together a mission which should fly, we hope, by the end of 2021. The current baseline is for two weeks in orbit and it could bring between 25-30 experiments. So the announcement of opportunity, which I hope will be out in the second half of 2017, will be open essentially to developing countries, but also to others. The experiments will be selected with the main criteria being that they have to be in line with the Sustainable Development Goals (SDGs).

President Donald Trump’s advisers are considering an industry proposal to send a manned spacecraft to repair and upgrade the Hubble Space Telescope within the next few years, according to people familiar with the matter. The discussions are still preliminary [...]

The Hubble repair proposal also has garnered administration officials’ attention because it appears to meet still other important White House criteria, according to these people. The goal is to put a lid on federal expenditures for space by fostering public-private partnerships, while devising projects that can be completed within the president’s current four-year term.[...]

The company twice presented its proposal to transition officials, according to one person familiar with the details.[...]

An administration representative declined to comment, except to say that transition officials lacked power to approve new projects and “it will be the responsibility of the NASA administrator to set NASA policy.” [...]

SNC's Dream Chaser Arrives at NASA Armstrong

NASA Armstrong Flight Research Center

Published on Feb 17, 2017
Sierra Nevada Corporation delivered its Dream Chaser spacecraft Jan. 25, 2017, to NASA's Armstrong Flight Research Center in California, located on Edwards Air Force Base. The spacecraft will undergo several months of testing at the center in preparation for its approach and landing flight on the base's runway.

The test series is part of a developmental space act agreement SNC has with NASA’s HYPERLINK Commercial Crew Program. The upcoming test campaign will help SNC validate the aerodynamic properties, flight software and control system performance of the Dream Chaser.

The Dream Chaser is also being prepared to deliver cargo to the International Space Station under NASA’s Commercial Resupply Services 2 (CRS2) contract beginning in 2019. The data that SNC gathers from this test campaign will help influence and inform the final design of the cargo Dream Chaser, which will fly at least six cargo delivery missions to and from the space station by 2024.

I take it this means a crewed version still might be possible in the future.
Title: Re: SNC Dream Chaser UPDATE Thread
Post by: Arch Admiral on 03/28/2017 05:50 AM
The problem with the crewed version is that it has to be launched inside a payload shroud with wings folded which vastly complicates the abort system.

The reason it has to be launched in a shroud is that otherwise the booster is highly unstable in pitch due to the lifting surface at the nose. Dyna-Soar tried to fix this problem with big tail fins on the boosters but wind tunnel tests revealed unpredictable interactions between the spacecraft wing and the booster fins.

Also, I think NASA would be scared stiff by the wing folding joints. The landing gear doors were a lot of trouble on Shuttle but the long wing joints on the "navalized" Dream Chaser are just asking for a burn-through.

Making Commercial Space Flight More Accessible

Draper Readies Dream Chaser for International Space Station

CAMBRIDGE, MA – Flight software developed by Draper is helping to bring routine commercial space flight one step closer to reality. The software will be on Sierra Nevada Corporation’s (SNC) Dream Chaser® spacecraft for resupplying the International Space Station (ISS). When the un-crewed spacecraft launches to the ISS, its mission will be to deliver six tons of food, supplies and fuel to the orbiting laboratory.

As an un-crewed spacecraft, Dream Chaser presents a unique set of challenges in its design and navigation. SNC envisioned a spacecraft that could land on a runway, similar to the Space Shuttle, so that it could be reused and put back into space within 60 days. SNC also wanted Dream Chaser to be resilient so that it could meet its goal of flying a minimum of 15 times.

For the Dream Chaser Cargo System, Draper addressed these challenges by applying its flight-proven capabilities that also enable cargo delivery to the ISS aboard Orbital ATK’s Cygnus spacecraft. The capabilities include mission automation and guidance, navigation and control (GN&C) software, as well as the human-rated fault-tolerant flight computer.

Draper used these same capabilities during the Constellation Program (CxP), when NASA had the Moon as a stepping stone towards missions to Mars. Now the company has brought those capabilities to one of the few spacecraft designated by NASA for resupplying the International Space Station under the Commercial Resupply Services (CRS-2) contract awarded to SNC.

Seamus Tuohy, director of space systems at Draper, believes Dream Chaser represents a new chapter in space travel. “The future of routine commercial space flight is quickly approaching, promising to make a trip into space as routine as air travel. Dream Chaser is an important step by showing how we can get to the Space Station and back quickly, easily and safely, and provide the vital cargo for making living and working in space possible for humans.”

The next test for Dream Chaser—a free flight and landing at NASA’s Armstrong Flight Research Center—will help validate the systems specially designed by Draper. The test flight will help confirm elements of the flight software and the flight control computer. It will also validate the spacecraft’s handling and performance characteristics during landing.

“Dream Chaser enhances the American capability to deliver and return ISS cargo, decreasing our reliance on foreign providers,” added Tuohy. “It also has the potential to increase use of hosted payloads and deployment of CubeSats by more industry and university partners.”

Gemini Software Heritage Shaping Human Spaceflight Today

Aviation Week, May 03, 2017 – When a United Launch Alliance rocket boosts Sierra Nevada Corp.’s Dream Chaser commercial cargo vehicle toward the International Space Station (ISS) at the end of this decade, it will find its way there with technology that has roots in the orbital rendezvous technology the government funded in the Gemini program more than a half-century ago.

The Charles Stark Draper Laboratory in Cambridge, Massachusetts, used government-funded guidance, navigation and control (GN&C) techniques dating from Gemini to build and program the guidance computer for the Apollo program, and it will use that same basic technology—upgraded dramatically over the years—for Sierra Nevada’s reusable robotic spaceplane...

Dream Chaser® Spacecraft Passes Major Milestone
Completes Successful Integration Review for Space Station Resupply Mission

SPARKS, Nev. (May 25, 2017) – Sierra Nevada Corporation (SNC) successfully passed the third integration milestone for the Dream Chaser program under the NASA Commercial Resupply Services (CRS2) program, bringing it a major step closer to providing resupply services to the International Space Station (ISS).

CRS2 Integration Review #3 (IR3) confirmed SNC’s Dream Chaser Cargo System design meets NASA’s key requirements and maximizes probability of mission success during future flights.  The spacecraft is scheduled for at least six missions between 2019 and 2024. The reliability of the Dream Chaser design was also thoroughly reviewed as part of NASA’s Phase I Safety Review Process, which successfully demonstrated safety and mission assurance criteria.   The reviews covered all stages of mission operations including ground, launch, flight and landing.

“Passing the third CRS2 integration milestone is a really big deal for the program and its future,” said Steve Lindsey, vice president of Space Exploration Systems for SNC’s Space Systems business area. “We are proud of this accomplishment and  are well on our way towards completing the next critical milestone and the remaining developmental phases.  It’s a great feeling to be executing all our milestones on schedule and to be moving forward to our operational flight.”

The spacecraft’s unique cargo design transports more cargo mass (5,500 kilograms) to the ISS each mission.  In addition, a significant amount of cargo, almost 2,000 kilograms is directly returned from the ISS to a gentle runway landing at a pinpoint location. Dream Chaser’s all non-toxic systems design allows personnel to simply walk up to the vehicle after landing, providing immediate access to time-critical science as soon as the wheels stop. .

The complex and thorough review process found no significant design, build or system issues and underscored the Dream Chaser’s readiness for flight.

The major elements of Milestone 3 included:     

    Successful completion of the NASA Phase 1 Safety Review
    32 Hazard Reports and 16 Safety Data Packages approved by NASA
    Dream Chaser Architectural Design’s met all CRS2 requirements (hardware, software, flight dynamics, thermal control, etc.)
    More than 100 detailed design documents were delivered to NASA along with 30+ design reviews
    During the three-day IR3 review, more than 1,000 charts were briefed to the approximate 45 member NASA and Federal Aviation Administration (FAA) team, which demonstrated that Dream Chaser is at Preliminary Design Review level of maturity
    Launch vehicle operations, outside subcontracts and agreements
    Range safety plan, as well as FAA, Federal Communications Commission (FCC) and National Telecommunications and Information Administration (NTIA) licensing
    5 Safety Review Phase 1 meetings were conducted prior to the IR3 review and involved the delivery of 46 individual Safety Data Packages developed under our S&MA team.


In addition to completing this milestone, the Dream Chaser atmospheric test vehicle is in preparations for flight testing that will help verify these designs. The spacecraft is currently testing at NASA’s Armstrong Flight Research Center in California, having just successfully completed Phase One ground testing leading up to its second free flight test later this year.

The solution will leverage Paragon’s patented Extruded Radiator (xRAD™) technology, a state-of-the-art, cost-effective radiator solution which eliminates the structural and thermal inefficiencies associated with bonded radiators structures.  The xRAD™ technology also increases vehicle integration flexibility and reduces development time, manufacturing risks, and manufacturing costs.  Delivery of flight radiators is to commence in early 2019 with deliveries through 2022.  As a part of the disposable cargo module, the radiators will burn up during reentry at the end of each mission.

“Paragon’s offering was a result of years of Paragon’s directed internal R&D funding that brought the technique and practical application out of the laboratory and onto the factory floor to benefit our customers that are needing better-value radiator solutions,” said Grant Anderson, President & CEO of Paragon.  “This multi-unit and multi-mission order will be just the beginning of a decades-long relationship to provide high quality and competitively priced radiator hardware to Sierra Nevada Corporation’s Dream Chaser family of vehicles.”

Earlier this year, SNC successfully passed the third integration milestone for the Dream Chaser under the NASA Commercial Resupply Services (CRS2) program, confirming that the company’s Dream Chaser vehicle can meet NASA requirements for transporting cargo to and from the space station. The reliability of the Dream Chaser design was also thoroughly reviewed as part of NASA’s Phase I Safety Review Process, which successfully demonstrated safety and mission assurance criteria. The reviews covered all stages of mission operations including ground, launch, flight, and landing.

“SNC is pleased to be working with Paragon on the Dream Chaser program,” said Mark Sirangelo, corporate vice president of SNC’s Space Systems business area. “Their radiator technology is a key component in SNC’s ability to deliver a safe, affordable, flexible and reliable system.”

Sierra Nevada Corporation’s Dream Chaser® Spacecraft has
Successful Captive Carry Test

 

SPARKS, Nev. (August 30, 2017) — Sierra Nevada Corporation’s (SNC) Dream Chaser engineering test article passed a successful Captive Carry test at NASA’s Armstrong Flight Research Center on Wednesday as part of the Phase Two flight test efforts to advance Dream Chaser progress toward orbital flight.

 

“We are very pleased with results from the Captive Carry test, and everything we have seen points to a successful test with useful data for the next round of testing,” said Lee “Bru” Archambault, SNC’s director of flight operations for the Dream Chaser program.

 

These activities are being conducted through a Space Act Agreement with NASA’s Commercial Crew Program (CCP), although the Phase Two flight tests will also be highly supportive of, and executed in parallel with continued work being done by SNC under NASA’s Commercial Resupply Services 2 (CRS2) contract. The Dream Chaser test vehicle has been upgraded to include several components being integrated into the Dream Chaser Cargo System design, allowing Phase Two tests to act as a bridge between previous work with CCP and the next-generation vehicle currently under development for cargo resupply missions.

 

During Captive Carry test #1, a Columbia Helicopters Model 234-UT Chinook helicopter successfully carried the Dream Chaser to the same altitude and flight conditions Dream Chaser experiences before release on a Free Flight test.

 

The SNC Mission Control Center team sent commands to Dream Chaser, monitored performance and collected critical test data designed to allow the team to refine Dream Chaser systems for peak performance on the actual Free Flight test day.

 

The Captive Carry test obtained data, evaluated systems such as radar altimeters, flush air data system, air data probes, navigation system, as well as overall system performance in a flight environment.

 

Successful data analysis, flight crew and flight control team proficiency, are critical ingredients needed for Certification of Flight Readiness.   All technical info from the Captive Carry flight tests will be evaluated by the SNC engineering team and shared with NASA counterparts.

 

This Captive Carry test is one of two scheduled for 2017.  Another Captive Carry test, designated Captive Carry #2, will incorporate fine tuning needs or lessons learned from today’s test flight.  A fully successful Captive Carry #2 test, once completed, clears the way for the Dream Chaser Free Flight test.

 

“This test is another indication the Dream Chaser is on track for meeting our key milestones on the way to orbital spaceflight.  We are excited to move through the remaining ground and flight testing to help inform our CRS2 orbital vehicle design and upcoming production,” said Steve Lindsey, vice president of Space Exploration Systems for SNC.

 

The Free Flight test is scheduled for later this year.

Great to see DC flying again!

Interestingly, N239CH's history shows that it only returned to the US this past May, after a stint of operations in Papua New Guinea.

Also interesting is that N239CH's "brother" at Columbia Helicopters is N242CH - which is Trump's former Chinook! :D

While SNC is focused for now on developing the cargo version of Dream Chaser, the company has not closed the door on developing a crew version. Lindsey said the company recently signed a five-year unfunded extension of its CCiCap agreement with NASA to support potential future development of a crewed vehicle.

“We have some unfunded milestones where NASA will come in and look at our requirements and how we’re developing our cargo vehicle, look at the path or trace to the crewed vehicle, and help us out,” he said of the extended agreement with NASA. “We’re going to do cargo first, and do the best we can with cargo and prove out the vehicle,” he said, “but our intent some day is to go back to crew as well. How and when is TBD.”

Via L2 coverage from the NASA side, today (Sunday, November 5) is the latest NET for the big landing test, Approach and Landing Test 2 (ALT-2). Previous dates were delayed to an issue that required an updated test review and of course the big issue was the lack of a chopper due to fire fighting duties.

Chopper was making its way back last week. Issue was resolved. Test date set....for TODAY.

There is no word from SNC as of right now.

So, they will either have delayed to a later date. Won't webcast it (like they didn't webcast the previous landing test). Or just announce a good test after the event.

They webcast captive carry 1. They have greatly improved their social media. But they didn't even mention captive carry 2, which was a bit strange, as we know that was completed.

I would note I can understand them being silent, as the last test was really unlucky and they are a commercial company who need to control their image (just like SpaceX and the others, by the way).

Best we can do is for everyone keep an eye on Armstrong.

For what it's worth, the two NASA planes that we were monitoring as part of a potential test on November 8th returned to LAX later that night. So either they are not related to the Dream Chaster flight (which is completely possible), or they will have to fly back to Edwards today.

Waiting for official confirmation...

Nothing showed up on the flight tracker. The helicopters usually don't show up, so that is not too much of a surprise. It's very possible that if there were some support aircraft, those too were helicopters. Additionally, they could have had planes which were a bit more stealth than commercial ones.  8)

Title: Re: SNC Dream Chaser UPDATE Thread
Post by: yg1968 on 11/14/2017 11:45 PM
Here is a transcript of today's Q&A (on twitter) with Steve Lindsey of SNC:

https://twitter.com/SierraNevCorp/with_replies

Question: 1st: Congrats!!! 2nd: the left landing gear appeared to develop a, "wicked shimmy" shortly after landing. Did that actually occur or was it some kind of optical illusion or camera artifact?

Answer: I didn't see that; good rollout so maybe an artifact?

Question: Will the cargo DC still have windows (like the test article)?

Answer: No windows on the cargo version - sad for a pilot like me 😟

Question: Do you already have an aspirational target date for the demo/maiden flight of the actual (not the test article) DC?

Answer: We are currently in discussions with @Space_Station on when our first flight will occur

Question: Looking to the future: can/will Dream Chaser launch with several launch providers after its initial flights with @ulalaunch? Such as @SpaceX, @Arianespace or @blueorigin?

Answer: We are assessing multiple launch vehicles for future missions. 

Question: What are your plans for DC in the post-ISS world?

Answer: We are looking at many different types of missions, to include stand alone science missions, satellite servicing missions, and crewed missions ... just to name a few.  We intend to be flying Dream Chasers for a long, long time. 

Question: what rocket do you guys plan to launch with?

Answer: Our first mission will be on an Atlas V rocket @ulalaunch .

Question: How many Dream Chaser spaceplanes does SNC currently plan to build and operate?

Answer: Total number will depend upon the customers and types of missions we fly.  Hopefully a whole fleet of Dream Chasers!

Question: does the Dream Chaser still have the capabilities preform an ISS orbit boost?

Answer: Yes, we do. 

Question: First off, thank you for your contributions To the space program, Steve. My question to you is: What lessons were learned from drop test 1 and what changed between the first flight and now?

Answer: We learned so many lessons from the first flight, I can't possibly list them here.  The same will be true from this flight.  And this is exactly why we flight test; to make our orbital vehicle/system better. 

Question: What’s the maximum amount of time Dream Chaser could stay on orbit, docked to the ISS?

Answer: For cargo/science resupply flights, 45-75 days.  But that's based on what @Space_Station has requested in their visiting vehicle traffic manifest; we can stay docked or berthed longer than that if needed. 

Question: Do you have internships available for college students that will provide hands-on experience with projects like Dream Chaser?

Answer: YES!! Go check out the SNC website - http://sncorp.com 

Question: For crewed flights, what abort options will Dream Chaser have if an emergency occurs during launch?

Answer: We have designed the Dream Chaser to be able to abort anytime during ascent (including while sitting on the launch pad).  For missions to the @Space_Station, we also have the ability to land at runways up the east coast of the United States.

Question: What is the future of this particular Dream Chaser vehicle after its completed all testing? Donating it to a museum?

Answer: Right now we plan to keep it in 'flyable storage' so we can use it for future test flights if needed.  It is also human rated, so when we build a crewed version in the future we'll do additional atmospheric flight test.  Then maybe to a museum!

Question: Because I think all LV's in dev't now should have REUSABILITY as a basic feature, what's SNC's aspirational target for number of reuse w/ minimal refurbishment for each D.C. spacecraft?

Answer: Our design goal is 15 flight reuse -- we'll get better data on their actual life once we start flying missions

Questions: 1) Has all the CFD/Modeling been done for launch/stress atop the Atlas V? 2) Were other firms' launchers modeled/tested? 3) Time/issues if converting to Astronaut Ferry Mission?

Answers: We've done a lot of CFD/Modeling work on the Dream Chaser and our Launch Vehicle.  We are investigating several different launch vehicles; this will include similar work.  We maintain a 'path to crew' with our vehicle; crew and cargo vehicles are about 85% common

Question: I am wondering; If the successful atmospheric Free-Flight test of @SierraNevCorp's Dream Chaser, on November 12, did not included a test-routine for the folding-wing design, when and how will that be tested?

Answer: We'll test the wing deployment system on the ground and in a vacuum & thermal chamber.  The wings are deployed on orbit - so they'll already be fixed in place prior to entry.

Question: My dad noted many similarities (visually) between Dream Chaser and X-38. Was that program the starting point for this one?

Answer: Similar, but different heritage from the X-38.  The Dream Chaser comes from NASA's HL-20 Program, which came from the Russian BOR-4 Program.  How's that for an interesting heritage?!

Question: In mid flight during the drop test,  the DC seemed to wobble from left to right. Was this normal?

Answer: Great question!  That 'wobbling' was actually an intentional 'Programmed Test Input', or PTI.  This set of maneuvers was designed to assess the responsiveness and stability of the vehicle and provide us better aerodynamic data.  Worked Great!!

Question: Why the lag on getting video out? It's so much easier for folks like me to retweet stuff when it's there to retweet - and we're ALWAYS hungry for webcasts!

Answer: It was Veteran's day weekend.  We flew at a closed airfield (Edwards AFB) -- and the men and women of the USAF deserved the weekend off!  We processed the video as soon as we had access to it.

Question: how many test flights do you think there will be after the most recent one?

Answer: We're assessing the data from this most recent test - our decision to execute additional test flights will be based on whether or not we accomplished all of our test objectives from this flight. 

Question: Was #DreamChaser being flown strictly via computer or was a human involved?

Answer: The Dream Chaser flew autonomously (via computers and pre-programmed commands).  However, we also had a flight control team capable of commanding the vehicle and analyzing telemetry in real time.

Question: Will the U.N. mission in 2021 land in the United States or outside the U.S?

Answer: We haven't made a decision on this -- but we are working this question with  @UNOOSA

Question: What's the transition has been like btwn space shuttle nd dream chaser...does smaller means less complicated or the opposite...in reference to design, aerodynamics, propulsion etc..

Answer: We took all of the lessons learned from the Space Shuttle Program and applied them to our design; making the vehicle as robust and simple as possible.  This will make Dream Chaser more reliable and less expensive to operate.

Question: I noticed that even when #DreamChaser is in contact with the ground on all 3 landing gears it is still pitched up somewhat. Most aircraft are pitched down a little. Why is that?

Answer: Our nose skid strut is a little higher but when at rest the vehicle is pretty level.  The shuttle nose gear was much shorter, and that resulted in much firmer 'slapdown' forces.  Our derotation and nose strut touchdown is much gentler by comparison

Question: what are the 2 most important safety features redesigned in DreamChaser vs Space Shuttle?

Answer: 2 that come to mind are:- We went from toxic chemicals (such as hypergolic fuels and hydrazine) to non-toxic fuels, which make for easier access to the vehicle and safer ground processing - Improved, tougher heat shield

I noticed this wobble in the video, and was about to post about it in concern before I saw this post.  I recall the lifting bodies tested in the '60s tended to have a roll instability, which at times caused loss of vehicles.  I believe a large central vertical stabilizer was added to the HL-10 at one point, to try and reduce this instability.

Good to see that the DC design not only anticipated this instability as a potential problem (which has obviously been designed out), but also that they incorporated an intentional roll instability in this ALT in order to see how well the avionics damped it out.

Great to see!

I believe it was the M2 F2.  It was susceptible to a phenomenon similar to a Dutch role at high angles of attack.  This led to an incident stemming from a temporary distraction from a helicopter that led to a late/overly aggressive pull-up which ended up producing the high angle of attack with the incident of instability.  This instability was quickly recovered from but resulted in a late landing gear deployment.  The landing gear was not fully deployed at touchdown and folded back into the aircraft.  As the M2 F2 did not have either wings nor a relatively flat bottom the resulting lack of deployed landing ended up in a rather spectacular series of ground loops.  With the last ground loop plopping the M2 F2 onto its back.  (This spectacular footage was used in the opening clips of the $6 million man).  The pilot suffered significant but not fatal injuries.  The injuries were not fatal because the cockpit stayed in essentially one piece.  Due to a design flaw in the original construction, the correction resulted in the cockpit being way overbuild to the original design specifications which would've been inadequate to save the pilot in this event.  Eventually, the program continued with a new lifting body design called the M2 F3 that had a 3rd center fin to correct the instability problem.`

Aren't we being naughty discussing in the update thread? To cap it off the M2 series was the inverted "half-cone" and the most radical of the lifting bodies. The X-24A/B (flat bottom) and HL-10 (cambered bottom) were more benign in handling especially after the glove was fitted to the HL-10 two outer vertical stabilizers... It was these two that led there design evolution to the X-38 and HL-20... The BOR-4/SPIRAL were not a true lifting body designs from entry to landing as their vertical stabilizers folded down to a conventional wing position in order to land. The HL-20 and Dream Chaser proved that the pure lifting body concept was sound aerodynamically subsonically to touchdown as we saw...

An SNC Update that slipped under the radar (which is why it refers to a free flight test later in the year).

Quote
Here is a brief overview of several tests that have been completed to date on the Dream Chaser at NASA’s AFRC:

Tow Testing

The Dream Chaser must undergo several tow tests to validate the performance of the spacecraft’s nose skid, brakes, tires and critical elements of the Guidance, Navigation and Control system of the Dream Chaser. During these tow tests, the vehicle is towed by a pickup truck to various speeds. Once the top speed is reached, Dream Chaser is then released from the tow hitch and the vehicle’s braking system is then used to bring it to a complete stop. Include link to new tow test video?

    20/30/40 mph Tow Tests: March 15 and May 2, 2017
    These tests were performed as part of a ramp-up approach to higher speed tow tests. Objectives included:  Verify ground navigation, verify control, verify differential braking capability, verify simultaneous braking capability and verify tire/rolling friction models.

    60 mph Tow tests: May 20, 2017
    These tests were performed as part of a ramp-up approach to the Captive Carry and Free Flight tests later this year. After three successful tow tests at this speed, the avionics and brakes operated as expected and the vehicle is ready for the Free Flight later this year. One final 60 mph tow test will be completed before the Free Flight Test.

Moments of Inertia (MOI) Tests: March 22 to April 1, 2017


SNC partnered with the Flight Loads Laboratory at NASA’s Armstrong Flight Research Center to perform mass properties measurement testing on the Dream Chaser. The vehicle mass properties were successfully characterized allowing the team to better estimate the flight performance. Testing the vehicle in multiple configurations over multiple test runs reduced the testing uncertainty and provided accurate results.

Airborne - Ground Resonance Test: April 24-26 2017

SNC, again partnering with the AFRC Flight Loads Lab, measured the structural response of the Dream Chaser spacecraft to programmed flight control system sweeps at various frequencies. This test was performed with the Dream Chaser in an airborne configuration (landing gear retracted) and resting on the Flight Loads Lab "soft support" system to simulate an airborne environment. This test was the sister to the Rollout - Ground Resonance Test performed in Louisville, Colorado in December 2016.

Radar Altimeter Calibration: April 28-29, 2017

These tests were completed in Hangar 4833 (the former Space Shuttle hangar used for Enterprise) at AFRC. This test involved two cranes lifting the test article at three different pitch angles and deploying the gear at the max crane height during each test case. The main objective of this test was to demonstrate the integrated functionality and performance of the radar altimeters with the landing gear stowed, during landing gear deployment, and after landing gear deployment. Additional objectives included demonstrating that the radar altimeters worked simultaneously as well as independently.

Ground and Airborne - Gain Margin Tests (GMT): May 15 and May 22-24, respectively

Our Guidance, Navigation and Control System engineers designed specific software filters to ensure the Dream Chaser structure responds well to flight control surface inputs.  Gain Margin Tests were performed in both ground and airborne configurations to evaluate specific flight control surface inputs and verifying fundamental laws of aerodynamics.  The airborne gain margin tests were performed on the flight loads lab and ground testing was performed while Dream Chaser was on its landing gear.

Additionally, the team just completed their first Captive Carry Test, allowing them to refine helicopter crew techniques, gather a wide variety of additional data on the vehicle and provide an opportunity for the flight control team to train prior to the Free Flight Test.

Sierra Nevada Corporation’s Dream Chaser spacecraft passes major NASA milestone after free-flight test:
https://www.sncorp.com/press-releases/snc-dream-chaser-passes-milestone-4b/

Quote from: SNC
Milestone 4B validated the spacecraft’s design for a safe and reliable return of cargo services to Earth through a gentle runway landing, signaling the program is one step closer to orbital operations. [...] The NASA Commercial Crew Program reviewed the data, confirming it fully met or exceeded all requirements and authorized full payment of the milestone.  Additionally, SNC collected a significant amount of additional information that will be used for the final vehicle design. [...]

The approach and landing test included intentional maneuvers both to assess the responsiveness of the Dream Chaser to control inputs and to measure the resulting stability of the vehicle under very dynamic, stressful conditions.  This showcased the aerodynamic capability of the Dream Chaser as well as performance of the integrated computer system that autonomously returned the vehicle to a safe runway landing. These are critical components for orbital missions to and from the International Space Station.

So in summary.

They got the milestone payment from NASA for this.

They have contracts in for solar panels to extend their duration on orbit (potentially allowing them to serve as a free flying laboratory)

They have contracts in to a landing gear supplier to ensure that's taken care of, which is pretty important given the trouble their first landing test had with landing gear re-purposed from an old plane (although a perfectly reasonable strategy to keep down costs for an experimental vehicle)

They are still in the running for NASA CRS contracts.

Which all together is pretty exciting. 2018 should be quite a years for SNC and DC.

Just to jog you memory John, the F-5 landing gear was an artifact of what NASA selected for the HL-20 test vehicle and just a continuation thereof... The orbital will use a new system.

They already won a CRS2 slot, not "in the running" anymore. Solar panels are needed for the Cargo variant as well. Landing gear was replaced after the first test flight

SPARKS, Nev. , February 07, 2018 – Sierra Nevada Corporation (SNC) received NASA’s Authority to Proceed for the Dream Chaser spacecraft’s first mission, with a launch window for late 2020. The mission will provide cargo resupply to the International Space Station under the Commercial Resupply Services Contract 2 (CRS2).

“SNC has been successfully completing critical design milestones as approved by NASA, and having a timetable for the first launch is another important step achieved for us,” said Fatih Ozmen, owner and CEO of SNC. “The team has worked so hard to get to this point and we can’t wait to fulfill this mission for NASA.”

Key Mission Capabilities:

- Delivers up to 5,500 kg (12,125 lb) of pressurized and unpressurized supplies and scientific research payloads
- Remains attached to the space station for extended periods so crew can transfer cargo and perform science laboratory operations 
- Flying laboratory that allows scientists to send commands, receive data in real-time
- Powered payload science experiments can operate continuously during the mission
- Critical science is conducted from the pressurized cabin (crew-tended or autonomous)
- Unpressurized cargo/experiments are transferred to or from the space station via robotic operations
- Returns up to 2000kg of cargo via pinpoint landing at NASA Kennedy Space Center (KSC) Shuttle Landing Facility (SLF) for -
immediate post-landing handover to customer, maximizing the integrity of data collected on-orbit     

“The Dream Chaser is going to be a tremendous help to the critical science and research happening on the space station,” said Mark Sirangelo, executive vice president of SNC’s Space Systems business area. “Receiving NASA’s Authority to Proceed is a big step for the program. We can’t wait to see the vehicle return to Kennedy Space Center to a runway landing, allowing immediate access to the science payloads being returned from the station.”

John Roth, Sierra Nevada Corp.: we still hope in the future to move from cargo to crew with Dream Chaser. If that means bringing in investors to develop a crew version, we would be open to that.

https://twitter.com/jeff_foust/status/968567887895105538

SNC mentioned the same thing a few days after winning CRS2. So that likely means that they have yet to find any investors for crewed DC.

Given the size and weight, I can't think there are that many vehicles you could launch it on. Falcon 9, Ariane 5 or 6, maybe the H-2b or H-3 successor? Not sure on H-3's time table. NGL and Vulcan of course.

Given the launches are for NASA would it matter if it launches from a foreign spaceport?

NASA may require there money be spent on domestic LV. NASA does use foreign LVs for some missions but that is typically a barter agreement with their partners eg ESA providing Ariane 5 for JWST.

I think the Europeans are thinking of launching Dream chaser for themselves, not NASA/ISS.  Japanese likely the same.

Sierra Nevada weighing options for launching future Dream Chaser missions
by Jeff Foust — April 18, 2018

COLORADO SPRINGS — As Sierra Nevada Corporation (SNC) prepares its Dream Chaser cargo vehicle for a first launch on an Atlas 5 in late 2020, the company expects to make a decision by the end of this year on the rocket that will launch later missions.

[...]

He declined to discuss specific vehicles under consideration but said SNC received “really great response from all the major providers.”

"SNC held the briefing in front of the Dream Chaser engineering test article that performed a glide flight at Edwards Air Force Base in California in November. That test article, developed under earlier NASA commercial crew awards, will now be placed in “flyable storage” at the company’s Colorado facilities.

Lindsey said the company will likely keep the test article in storage until the company is ready to resume development of a crewed version of Dream Chaser. “We’re going to keep it in a condition ready to fly,” he said. “We’ll modify it for flying crew, put a pilot in there and do some testing in the future.” "

Previous statements made this week indicated that 80% of the 0.75 cargo version will be compatible with the potential manned Dream Chaser - it would be wonderful in my opinion if a paying customer came forward to complete the development of a manned Dream Chaser.

From: https://news.thomasnet.com/companystory/sakor-technologies-selected-to-build-test-system-for-dream-chaser-atmospheric-flight-control-system-

SNC has now contracted for a TOA to surface flight control simulator.

SAKOR Technologies, Inc., a recognized leader in the implementation of instrumentation products for dynamometer testing, announces that it has supplied a test system to Southwest Research Institute® (SwRI®) to be used to test the atmospheric flight control system for the Dream Chaser® spacecraft. Dream Chaser is a lifting-body, reusable, crewed or uncrewed horizontal-landing vehicle. It is owned and operated by Sierra Nevada Corporation (SNC) and is designed as a space utility vehicle for low-Earth orbit.

SwRI, headquartered in San Antonio, Texas, is one of the oldest and largest independent, nonprofit, applied research and development organizations in the United States. Contracted by SNC to design and build the atmospheric flight control system, SwRI selected SAKOR to build a sophisticated system to exercise Dream Chaser’s new control system and simulate flight from atmospheric interface to landing. The system characterizes overall design performance as well as dynamic response to physical forces typically experienced in standard and extreme flight conditions.

The Dream Chaser spacecraft features seven control surfaces and the SAKOR-designed test system features seven dynamometers, each simulating dynamic loads on a specific control surface.

SAKOR’s DynoLAB™ data acquisition and control system controls the entire test stand, acting as a space craft emulator. Sending test profiles to the atmospheric flight controller as well as simulating force feedback from each control surface, DynoLAB communicates directly with the atmospheric flight co

Perhaps factor in the current administration plans to splash ISS in 2025 instead of the expected extension the partners were believing to happening...

Also, they are still looking ahead to possibly building a crewed version.  If they don't think they would be able to afford building 3 (2 cargo, 1 crew), I wouldn't be surprised to learn they had forgone the second version to still keep the crewed hope alive.

See below:

Some interesting stuff on DC:

Quote from: page 20 of the OIG report
Specifically, Sierra Nevada has committed to using Atlas V launch vehicles for its first two cargo resupply missions but the company is considering alternative launch vehicles currently under development to lower their costs for future NASA missions. Public statements from launch vehicle providers have proposed prices ranging from roughly $90 million to $120 million per launch. While the Atlas V is highly reliable with a 100 percent success rate after more than 70 launches, it has a list price of $175 million for the configuration needed for Sierra Nevada’s missions. Because Sierra Nevada’s cargo flights are procured under a fixed-price contract, any reduction in its launch costs accrue to Sierra Nevada’s benefit. However, the CRS-2 contract allows NASA to renegotiate mission pricing if a contractor uses an alternative vehicle. Any renegotiation would need to be finalized by early 2019 should Sierra Nevada plan to use an alternative launch vehicle for its third CRS-2 mission, which could occur as early as 2022. NASA’s CRS-2 contract with Orbital ATK has similar contract language to negotiate lower per-mission prices to reflect cheaper launch costs if the company uses ULA’s Vulcan launch vehicle instead of the Atlas V.

More on DC:

Quote from: pages 27 and 28 of the OIG Report
Sierra Nevada’s plan to build a single Dream Chaser spacecraft for CRS-2 missions is a single point-of-failure that represents substantial technical and schedule risks for the ISS Program.[69] During a visit to Sierra Nevada in June 2017, company officials told us they had no plans to build a second Dream Chaser. In August 2017, ISS Program officials said Sierra Nevada was considering building a second Dream Chaser to be completed by 2021, but no decision had been made as of October 2017. In the event of a failure, Sierra Nevada officials told us in June 2017 that a second spacecraft could be built from spare parts without additional costs to NASA.

[69] For the first CRS-2 mission, the Dream Chaser will be required to demonstrate additional orbital maneuvers before approaching the ISS. Other cargo vehicles such as the Cygnus, European cargo spacecraft, and Japanese cargo spacecraft were allowed to berth with the ISS on their maiden flight after performing similar maneuvers.

Simonetta di Pippo mentioned that the UN mission should happen in 2021 or 2022 depending on when the first flight of DC happens. It would last between 2 to 3 weeks but would not go to the ISS. There would be about 25 to 30 micro-gravity experiments plus some experiments outside of DC. Each experiment must have at least one sustainable development goal. It's open to developed countries but there is a focus on developing countries. Working with SNC on the announcement of opportunities.  It's a triangular cooperation between one or more developed country, developing or emerging countries and the UN Office for space affairs.
