Weigel: The second Vulcan flight, carrying the first @SierraSpaceCo cargo Dream Chaser to the ISS, is currently scheduled for February 2023."We'll be ready when they're ready."
During the Starliner press conference of yesterday, it was mentioned that the first mission of Dream Chaser is scheduled for late February 2023. It's at 38 minutes of the video: https://forum.nasaspaceflight.com/index.php?topic=51827.msg2369726#msg2369726

Quote from: deadman1204 on 05/23/2022 01:32 pmDreamchaser was always gonna be the 2nd Vulcan launch.Not that it matters but Dream Chaser was supposed to the first Vulcan launch initially but it got bumped to second a while ago.
Dreamchaser was always gonna be the 2nd Vulcan launch.
With the completion of the first Vulcan rocket around the corner next month, the question is whether any components for the second Vulcan to be used to launch the Dream Chaser spaceplane are being fabricated.
Andrei K asked DutchSatellites,"So, what will be launched in flight #2 ? NSSL payloads need at least 2 prior launches, don’t they? Does that leave only the Project Kuiper sats?"DutchSatellites answered, "Beside Dream Chaser launches & beside the NSSL contract & the Kuiper contract, @ulalaunch has contracts in place for launching several commercial payloads. One of those might be available for Vulcan flight #2. If not, then there is always the mass simulator @torybruno mentioned."

Hate to waste a second flight on a Mass Simulator. I wonder what it would take for Gwen to launch Starlinks on a one off for this flight. If nothing was available.

If nothing was available.I would bet that the first-time one-off integration costs (and risks of new engineering) would exceed SpaceX's internal marginal costs for an additional Falcon launch. Right now they're popping out an entire second stage every four-ish days, which is still hard to get my head around.
At least two of those are, per my sources, commercial comsat launches.
It does seem kind of silly to fly a real customer payload on the first flight, and then a mass sim on the second flight. If (somehow, I think this scenario is pretty unlikely) no customer payloads could be found for flight 2 on short notice, could they consider bumping Peregrine to the second flight and flying the mass sim on flight 1? Would also give Astrobotic a bit more schedule margin if there are any last-minute integration challenges (IIRC, they still needed to install part of the propulsion system?)
Apart from the maiden launch with Peregrine and 2 Kuiper demo sats, 19 awarded NSSL Phase 2 launches, 38 awarded Kuiper launches and 6 awarded Dream Chaser CRS2 launches, Vulcan also managed to score at least 6 not publically disclosed (as of yet) commercial launches. At least two of those are, per my sources, commercial comsat launches.The total number of ordered Vulcan launches exceeded 70 late last year.
Some news: Dream Chaser’s debut is delayed until at least mid-December. This extends NASA’s reliance on Falcon 9 for crew *and* cargo. More critically, it also raises questions about Vulcan’s launch manifest and path to certification.

The company hosted its first-ever official training for astronauts from NASA and JAXA to learn the innerworkings of the world’s first commercial spaceplane.The astronauts – Jasmin Moghbeli (United States) and Satoshi Furukawa (Japan) – are two members of the upcoming SpaceX Crew-7 mission to the International Space Station (ISS). During their planned six-month stay, Dream Chaser will make its maiden voyage to deliver cargo to the ISS as part of NASA’s Commercial Resupply Services-2 (CRS-2) contract.“We are honored to provide NASA cargo resupply missions to the International Space Station. The astronaut training is another important milestone as we complete the final preparations for Dream Chaser’s first mission,” said Sierra Space CEO Tom Vice. “Our team provided a comprehensive training experience for these Crew-7 members to prepare them for when Dream Chaser berths at the ISS.”Sierra Space compiled an eight-hour training session that took place on March 7 at the company’s Louisville, Colorado facility. Company specialists conducted the training, which was divided into four sections. Parts 1 and 2 were classroom training, while Parts 3 and 4 involved a full-size mock-up of Dream Chaser:Part 1: Dream Chaser Overview – Sierra Space team members gave Moghbeli and Furukawa a full briefing on Dream Chaser. Topics covered included systems identification and function, mission profiles (from launch and rendezvous to reentry and landing), crew interfaces and operations (i.e., types of cargo, how to load/unload, etc.). At the end of Part 1, astronauts walked away with a full understanding of the hardware they will encounter on Dream Chaser once it is at the ISS.Part 2: Rendezvous and Proximity Operations (RPO) – This portion of the training covered required actions as Dream Chaser makes its approach and officially berths with the ISS. Sierra Space employees carefully reviewed the timeline, profile and procedural operations of the high-level system configuration involved in this critical part of the mission.Part 3: Dream Chaser Hardware Familiarization and Scenarios – The astronauts moved into a full-size mock-up of Dream Chaser. As they walked through the vehicle, Sierra Space employees identified hardware/systems and taught the astronauts how to operate and/or interface with each one. The astronauts also learned vehicle ingress/egress procedures, as well as discussed off-nominal scenarios.“This was the portion of the training where the astronauts were blown away by Dream Chaser’s massive size, often commenting, ‘Wow, you can fit a lot of cargo in here,’” said Krista Abler, with Sierra Space’s Flight Operations Mission Training team. “You can look at CAD drawings or read about Dream Chaser’s dimensions all day long. But its immense capacity doesn’t really register until you crawl inside. I think this is a reason why NASA is excited about our vehicle.”Part 4: Cargo Transfer Scenarios – During the final portion of training, the astronauts learned how to properly and safely install/remove cargo from Dream Chaser, using the same procedures and operational tools as they will on orbit. They practiced with numerous restraints (i.e., straps, beams, etc.), identified hazards associated with cargo operations and ran scenario drills.“This was probably the most important lesson of the day because the whole point of Dream Chaser coming to the ISS is to deliver cargo,” Abler said.Press release photo captions:QuoteCrew 7 Astronauts Train in Sierra Space Dream Chaser mockupQuote NASA’s Jasmin Moghbeli trains in Sierra Space's Dream Chaser spaceplane mockup

Sierra Space’s Dream Chaser® Spaceplane Comes to LifeMAY 31, 2023Sierra Space, a leading, pureplay commercial space company building the first end-to-end business and technology platform in space, is thrilled to announce the successful power up of its revolutionary Dream Chaser® spaceplane. Dream Chaser represents a groundbreaking leap in space transportation technology, designed to provide reliable and cost-effective access to space for a wide range of applications. With its unique lifting body design, the spaceplane combines the flexibility of an aircraft with the capabilities of a spacecraft, revolutionizing space travel.The power-up of Dream Chaser signifies the activation of its integrated systems, showcasing the culmination of years of rigorous engineering, design, and testing. Sierra Space simulated the power that will be generated from Dream Chaser’s solar arrays once on orbit. Test engineers plugged that power into Dream Chaser and began turning on systems. Sierra Space exercised flight computers, base processors and low-voltage distribution units.“This is a milestone that points to the future and is a key moment in a long journey for Dream Chaser.” said Tom Vice, CEO of Sierra Space. “With this significant achievement, our Dream Chaser spaceplane is poised to redefine commercial space travel, opening up new possibilities for scientific research, technological advancements, and economic opportunities in space.”The successful test was a key moment for the progress of space technology after years of design and development across Sierra Space, enabled by the accomplishments of many teams from system level design to final assembly and test.[...]

Here's my scenario: The launch of the USSF-106 aboard the Vulcan could come first, followed by the maiden orbital launch of the Dream Chaser. After all, Sierra Nevada might give itself additional time in the second half of 2023 to prepare the Dream Chaser vehicle Tenacity for encapsulation inside the Vulcan assigned to the first Dream Chaser launch and eventual launch.

After all, Sierra Nevada might give itself additional time in the second half of 2023 to prepare the Dream Chaser vehicle Tenacity for encapsulation inside the Vulcan assigned to the first Dream Chaser launch and eventual launch.USSF-106 is an NSSL flight. NSSL rules require that Vulcan Centaur must fly at least two successful missions before ti flies an NSSL mission. In theory I suppose ULA could fly a Kuiper mission as the second mission, except that Kuiper probably won't fly a full-up mission until after the first two test satellites fly (on Vulcan Centaur's initial flight) and the test results have been evaluated.
Since NSSL rules require the Vulcan rocket to fly two successful missions before being certified for NSSL launches, I should mention that because the Dream Chaser Tenacity was recently powered up for the first time on May 31, it might make its first orbital flight in a few months after the Peregrine is launched.

Ken Shields of Sierra Space says the first Dream Chaser spaceplane will be heading to Plum Brook in the next week or two for testing, then to KSC. Current plans call for launch no earlier than March 2024.
Not a clean room because it's not needed. The factory in itself meets the required cleanliness levels (which are not at clean room levels anyway). What the image shows is nearly identical to SpaceX mounting solar arrays to Dragon (version 1) in the HIF at LC-40, or attaching the trunk to the capsule in those days (2012). And that was for the first ever Dragon that visited the ISS.

Unless things change, it is unlikely that a docking port will be available in March. There are two ports. One will be occupied by Crew-8 and the other will occupied starting March 4 by CRS-29, statistically for at least 30 days. (Note: data from Wikipedia. I have no other info.) https://en.wikipedia.org/wiki/SpaceX_Dragon_2#List_of_flights

This launch is not scheduled yet. April is just a "tentative" launch readiness target for Dream Chaser. Neither NASA nor ULA have commited to that date. No entry in NASA launch schedule, and way to quick turnaround between the first two launches of a new rocket.Realistically it will launch in Q3 if there are no issues with first Vulcan launch.

It is unlikely there will be more than 3 Vulcan Centaur launches in 2024, IMO. More likely just 2 with the Dreamchaser launching NET than late Q3, IMO.
On a slightly more serious note. ULA launched Atlas V eight times from SLC-40 in 2014 and in 2015, while also launching Atlas V from Vandy and Delta IV from SLC-37B for a total of 12 launches each year.SLC-40 is configured for both Vulcan and Atlas, and I think I remember Jim saying posting at least some of the pre-launch processing can be done in parallel for one Atlas V and one Vulcan. Therefore, it may be possible to exceed the 2015 eight-launch record.

Not the current one launch pad crew for ULA. Therefore more than 6 launches from pad SLC-41 during 2024 isn't likely.

Vulcan on the pad for its first launchJanuary 5, 2024[...]If Cert-1 is successful, he said the company could be ready for the second certification launch, Cert-2, as soon as April. That schedule will depend on the readiness of its payload, Sierra Space’s Dream Chaser spaceplane, as well as when the International Space Station would be able to support the arrival of that vehicle.Peller said the two BE-4 engines for that second launch are complete and are at a Blue Origin test site in West Texas for acceptance testing. The booster and Centaur upper stage are in final assembly at ULA’s Decatur, Alabama, factory. “That’s all coming together to support delivery down here at the launch site and align with that timeline,” he said.[...]
Is the readiness of Dreamchaser the pacing item on this flight now rather Vulcan.
United Launch Alliance, or ULA, has set aside the next 60 days to review data from the "Cert-1" certification mission that launched on Monday morning, they said. If the data looks good from that flight, the company will move into preparations for the next launch. Wentz said the earliest opportunity to launch this Cert-2 mission is "April-ish."The BE-4 rocket engines that will power this Vulcan are in final acceptance testing at Blue Origin's facilities in West Texas, the officials said. The Vulcan core stage and Centaur upper stage are also in final assembly in ULA's main factory in Decatur, Alabama. The hardware readiness should be capable of supporting an April launch.https://arstechnica.com/space/2024/01/after-its-impressive-first-flight-heres-whats-next-for-the-vulcan-rocket/

So what is the timeline for this second launch? It would seem that if they are shooting for an April launch, the BE4s would need to be getting to the main body about now. That would mean Feb is assembly and transport, then march is stacking and prep. Will they do a booster test fire like on CERT 1?

That would mean Feb is assembly and transport, then march is stacking and prep. Will they do a booster test fire like on CERT 1?This is not for launch. This is on the vibration table at NASA's Neil Armstrong Test Facility in Ohio, and it is the first time ever that Dream Chaser has been mated to a Shooting Star module. So there is still a deal more of testing to do on this vehicle before it can be shipped to Kennedy Space Center for its processing for launch. April is a very notional placeholder date, especially since Starliner CFT could likely well also launch during this time period and might even bump it due to having priority.
Will they do a booster test fire like on CERT 1?
Quote from: DrTadd on 02/01/2024 07:56 pmWill they do a booster test fire like on CERT 1?no and Cert 1 didn't do it either. A pathfinder did.
Thank you. I was remembering ULA doing a hot fire. It was like a minute or two burn.Was curious if they would do that for CERT 2 given the importance of the launch.
Considering the loss of Dragon in CRS-7, will Dream Chaser have any abort options for this flight?
This flight isn't launching in April
Sierra Space seeks a Special Temporary Authority for EMI/EMC testing of its Dream Chaser spacecraft planned to be launched in summer of 2024 for a demonstration mission to support cargo delivery to and from the International Space Station. This testing is to be conducted in partnership with NASA and NTS Technical Systems (Element Materials Technology). Sierra Space is requesting an STA for EMC and EMI testing to occur between March 24th, 2024, and September 20th, 2024. The testing will support Sierra Space Corporation’s DC-101 mission using the Dream Chaser Cargo System (DCCS), as part of the NASA Commercial Resupply Services. See also Exhibit A.
This testing is to be conducted in partnership with NASA and NTS Technical Systems.It will be conducted approximately 60 days prior to launch most likely by NTS Technical Systems (a NISTdesignated, US Conformity Assessment Body for EMC) in the High-Bay of the Space Station ProcessingFacility (SSPF) at the Kennedy Space Center (an NTIA authorized testing facility in Florida).

Given this delay, will this still be the 2nd Vulcan launch?

Don't matter what's on them i would think.Question is what else do they have to go up? Does amazon have a pile of satellites ready? Would they offer a cost break given the near perfect nature of the CERT 1 launch?

Whatever discount they give, it wouldn't be cheaper than launching on a Falcon 9.
Key accomplishments in this first critical phase of pre-flight testing included: the completion of Sine Vibration Testing (in all three axes or directions), a Separation Shock Test that simulates the separation of the Dream Chaser from Shooting Star and a test that involved deploying the spaceplane’s wings. These tests evaluated Dream Chaser’s performance under the stresses of launch, operation in orbit and ability to communicate with the International Space Station (ISS).
Following these critical test phases, the Shooting Star cargo module was de-mated from Dream Chaser and transported from the Armstrong Test Facility’s Space Environments Complex (SEC) to the nearby In-Space Propulsion (ISP) facility. Soon, Dream Chaser will be transported to the ISP facility to join the cargo module, where the two spacecraft will begin thermal vacuum testing, a crucial step in the journey towards the launchpad and another milestone in Sierra Space’s mission to redefine the future of space commercialization.
Sierra Space filed for another FCC permit, apparently for Dream Chaser on orbit communications. Unfortunately they haven't made any of the exhibits public. The NET date is September.0441-EX-ST-2024
