CONTRACT RELEASE C20-005
NASA Awards Contract to Launch CubeSat to Moon from Virginia
 
Part of the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility in Virginia, Launch Complex 2 is Rocket Lab’s second launch site for the Electron rocket. Rocket Lab will launch NASA’s Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) CubeSat mission to the Moon from the Virginia launch site in early 2021.

NASA has selected Rocket Lab of Huntington Beach, California, to provide launch services for the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE (https://www.nasa.gov/press-release/nasa-funds-cubesat-pathfinder-mission-to-unique-lunar-orbit)) CubeSat.

Rocket Lab, a commercial launch provider licensed by the Federal Aviation Administration, will launch the 55-pound CubeSat aboard an Electron rocket from NASA’s Wallops Flight Facility in Virginia. After launch, the company’s Photon platform will deliver CAPSTONE to a trans-lunar injection. The engine firing will allow the CubeSat to break free of Earth’s gravity and head to the Moon. Then, CAPSTONE will use its own propulsion system to enter a cislunar orbit, which is the orbital area near and around the Moon. The mission is targeted for launch in early 2021 and will be the second lunar mission (https://www.nasa.gov/content/ladee-liftoff-the-journey-begins) to launch from Virginia.

“NASA’s Launch Services Program (LSP) is pleased to provide a low-cost launch service for CAPSTONE and to work with Rocket Lab on this inaugural NASA launch from their new launch site at the Mid-Atlantic Regional Spaceport in Virginia,” said Ana Rivera, LSP program integration manager for CAPSTONE at NASA’s Kennedy Space Center in Florida. LSP will manage the launch service.

“This mission is all about quickly and more affordably demonstrating new capabilities, and we are partnering with small businesses to do it,” said Christopher Baker, Small Spacecraft Technology program executive at the agency’s headquarters in Washington. “This is true from the perspective of CAPSTONE’s development timeline, operational objectives, navigation demonstration and its quickly procured commercial launch aboard a small rocket.”

Following a three-month trip to the Moon, CAPSTONE will enter a near rectilinear halo orbit, which is a highly elliptical orbit over the Moon’s poles, to verify its characteristics for future missions and conduct a navigation demonstration with NASA’s Lunar Reconnaissance Orbiter (https://www.nasa.gov/mission_pages/LRO/main/index.html). CAPSTONE will serve as a pathfinder for the lunar spaceship Gateway (https://www.nasa.gov/topics/moon-to-mars/lunar-gateway), a key component of NASA’s Artemis (https://www.nasa.gov/specials/artemis/) program.

“CAPSTONE is a rapid, risk-tolerant demonstration that sets out to learn about the unique, seven-day cislunar orbit we are also targeting for Gateway,” said Marshall Smith, director of human lunar exploration programs at NASA Headquarters. “We are not relying only on this precursor data, but we can reduce navigation uncertainties ahead of our future missions using the same lunar orbit.”

The firm-fixed-price launch contract is valued at $9.95 million. In September, NASA awarded a $13.7 million contract (https://www.nasa.gov/press-release/nasa-funds-cubesat-pathfinder-mission-to-unique-lunar-orbit) to Advanced Space of Boulder, Colorado, to develop and operate the CubeSat.

After a final design review this month, Advanced Space and Tyvak Nano-Satellite Systems Inc. of Irvine, California, will start building and testing the spacecraft.

CAPSTONE is managed by NASA’s Small Spacecraft Technology program within the agency’s Space Technology Mission Directorate. Advanced Exploration Systems within NASA’s Human Exploration and Operations Mission Directorate supports the launch and mission operations.

That award document is one of the most interesting things I've read all year, thank you for providing it.

In particular the quote from the part dealing with Momentus' bid: "The first significant weakness was due to the proposed launch vehicle core stage propulsion systems (engines and stages) being in the early development stage. The associated test schedule poses significant risk to completing development and qualification making it unlikely that they
will meet the launch period requirement. "

This is the most professional way of saying "there's not a chance they're going to launch by that date" I've ever seen. I think I might keep that quote on hand for a lot of the press releases from new rocket companies we see around here  ;D

Finally, that man who wrote that report has clearly written CAPSTONE way too many times.

How small launcher Rocket Lab plans to pull off its first mission to the Moon next year
Moving beyond Earth orbit to lunar orbit

By Loren [email protected]  Jun 17, 2020, 8:00am EDT

Rocket Lab is known for launching tiny satellites into Earth, but the company has big plans to venture deeper into space, with its first mission to the Moon set for next year. Thanks to a contract with NASA, Rocket Lab will send a small spacecraft called CAPSTONE into orbit around the Moon to test out how to navigate in lunar orbit and help human missions to the Moon in the future.

Hi folks, I just got back from a Christchurch Aerospace meetup where Peter Beck Zoomed in and talked about what Rocket Lab is up to. I think just about everything he said was already known (there was nothing new about the recovered stage that hasn't already been talked about), but one thing he mentioned was that the capstone mission would be launching in April 2021. I'm pretty sure I haven't heard anything more accurate than "mid 2021" so I figured I'd pass it along.

He also mentioned that the spacecraft would do a super low pass over the moon, getting really close high res shots before heading out into a heliocentric orbit.

Rocket Lab to Launch NASA Funded Commercial Moon Mission from New Zealand

The CAPSTONE mission will be Rocket Lab’s first launch to the Moon

Long Beach, California. August 6, 2021 – Rocket Lab, the leading launch and space systems company, today announced it will launch the CAPSTONE mission to the Moon from Launch Complex 1 in New Zealand from Q4 2021. It will be Rocket Lab’s first launch to the Moon. CAPSTONE (the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment) aids NASA’s Artemis program, which includes landing the first woman and the first person of color on the Moon and establishing a long-term presence there.

Launching on an Electron launch vehicle and deploying from Rocket Lab’s Photon spacecraft platform, CAPSTONE is a 55-pound satellite created by Advanced Space that will serve as the first spacecraft to test a unique, elliptical lunar orbit. As a precursor for Gateway and other Artemis elements, an international and commercial Moon-orbiting outpost that is part of NASA’s Artemis program, CAPSTONE will help reduce risk for future spacecraft by validating innovative navigation technologies and verifying the dynamics of this halo-shaped orbit.

The mission is the first time Rocket Lab will use its Photon spacecraft platform as a trans-lunar injection stage to place a satellite on a trajectory that will take it beyond Earth orbit to the Moon. After lifting off on Electron to an initial elliptical low Earth orbit, Photon will separate and use its 3D printed HyperCurie engine to provide in-space propulsion to allow CAPSTONE to break free of Earth’s gravity and set a course for the Moon. After deploying the CAPSTONE satellite, Photon will continue on its own trajectory to conduct a lunar fly-by, while CAPSTONE will use its own propulsion system to enter a cislunar orbit.

Following a three-to-four-month trip to the Moon, the CAPSTONE CubeSat will enter a near rectilinear halo orbit (NRHO), which is a highly elliptical orbit over the Moon’s poles. During its six-month primary mission in orbit around the Moon, CAPSTONE will validate the propulsion requirements for maintaining this type of orbit as predicted by models, reducing logistical uncertainties for future missions. It will also test the accuracy of innovative spacecraft-to-spacecraft navigation solutions as well as demonstrate capabilities for commercial support of future lunar missions. The NRHO provides the advantage of an unobstructed view of Earth in addition to coverage of the lunar South Pole.

Originally slated for lift-off from Rocket Lab’s Launch Complex 2 in Virginia, the CAPSTONE mission will now take place from Launch Complex 1 to support a Q4 launch window.

“Flexible isn’t a word usually used to describe lunar missions but operating two launch complexes gives us the freedom to select a site that best meets mission requirements and schedule,” said Rocket Lab Chief Executive Officer, Mr. Peter Beck. “Our team is immensely proud to be launching one of the first pathfinding missions to support NASA’s goal of delivering a sustainable and robust presence on the Moon. We’ve teamed up with the NASA Launch Services Program on previous Electron missions to low Earth orbit, so it’s exciting to be working with them again to go just a bit further than usual…some 380,000 km further.”

Advanced Space of Colorado, a leading commercial space solutions company, owns the satellite and operates the mission. CAPSTONE development is supported by NASA’s Space Technology Mission Directorate via the Small Spacecraft Technology Program at NASA’s Ames Research Center in California’s Silicon Valley.  Advanced Exploration Systems within NASA’s Human Exploration and Operations Mission Directorate supports the launch and mission operations. NASA’s Launch Services Program at Kennedy Space Center in Florida is responsible for launch management.

Both Mahia and Wallops are at about 39 degrees latitude; they differ only in that one is north and the other south. The substantive difference is that due to overflight rules, you can't do SSO from Wallops without a bit of a dogleg, but that's not an issue for CAPSTONE naturally.

CAPSTONE’s CubeSat Prepares for Lunar Flight

Small spacecraft will play a big role in lunar exploration, including a Moon-bound CubeSat launching later this year.

The Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, or CAPSTONE, mission team is making the final preparations for the spacecraft that will make CubeSat history over a series of technological and operational firsts for the small platform.

Planned for launch in 2021, CAPSTONE will fly in cislunar space – the orbital area near and around the Moon – and demonstrate an innovative spacecraft-to-spacecraft navigation technology. CAPSTONE also will test out a unique lunar orbit that Gateway will use as the Moon-orbiting outpost for NASA’s Artemis program.

CAPSTONE will use a hydrazine-fueled propulsion system during most of its three- to four- month journey to the Moon. This line of propulsion system, developed by Stellar Exploration Inc. of San Luis Obispo, California, is a recently developed and flight-proven system developed for use on CubeSats. The team recently completed a fueling and final test-fire of CAPSTONE’s propulsion system at Stellar Exploration’s facility and is integrating the system with the spacecraft.

But before CAPSTONE fires its own thrusters, Rocket Lab’s Electron rocket will launch the mission from Earth carrying the CAPSTONE spacecraft integrated onto its new Lunar Photon upper stage/spacecraft. For the mission, Lunar Photon will serve as an upper stage to get CAPSTONE to a highly efficient ballistic lunar transfer trajectory designed by Advanced Space of Colorado. About seven days after launch, after a series of orbit raising maneuvers and the final trans-lunar injection burn, Photon will release CAPSTONE. After the deep space, low energy transfer, the CAPSTONE spacecraft will insert itself into the near rectilinear halo orbit. At the same time, Lunar Photon will continue to a separate orbit for its safe disposal.

The CAPSTONE spacecraft is fast approaching completion. Near-term plans include continued integration, testing, and international shipment of the spacecraft in late September. Rocket Lab has identified its Launch Complex 1 in New Zealand as the CAPSTONE launch site. Onsite launch preparations will include checkouts and fueling of the CAPSTONE spacecraft and its subsequent integration with Photon.

In May 2021, New Zealand signed the Artemis Accords with NASA – a set of principles that reinforce and implement the 1967 Outer Space Treaty. The agency aims to assemble the broadest and most diverse international space exploration coalition in history. To date, 12 nations have signed the accords, and conversations with other nations are ongoing.

CAPSTONE is commercially owned and operated by Advanced Space in Westminster, Colorado. It represents an innovative collaboration between NASA and industry to provide rapid results and feedback to inform future exploration and science missions. Tyvak Nano-Satellite Systems of Irvine, California, is building the microwave oven-sized 12-unit CubeSat platform.

NASA’s Small Spacecraft Technology program within the agency’s Space Technology Mission Directorate funds the demonstration mission. The program is based at NASA’s Ames Research Center in California’s Silicon Valley. Advanced Exploration Systems (AES) within NASA’s Human Exploration and Operations Mission Directorate funds the launch and supports mission operations. The Launch Services Program at NASA’s Kennedy Space Center in Florida manages the launch service.

The launch of CAPSTONE is targeted for no earlier than March 19, 2022, according to NASA's Andres Martinez.

Most of this podcast is about Tom, start around 45min to hear about Capstone and RL launch. COVID has thrown spanner works as Capstone team need to go through MIQ (Managed Isolation and Quarantine)when coming into NZ, problem is booking slot in MIQ that coincides with launch window. Now that NZ is struck with COVID in community, bypassing  MIQ maybe option for Capstone team.

RL had to build facility at Mahia to fuel satellite with Hydrazine which maybe part of reason for picking Wallops in first place.

At this rate the AFTS for Wallops could be sorted and they can launch from there.

Beck has noted they want to get through "a couple" of important missions first before devoting attention to another recovery attempt, and CAPSTONE is surely one of those, so most probably not.

Does Capstone need specific launch window that matches moon's orbit? Give the multiple burns over day to raise orbit before TLI I assumed it would matter much.

Regarding the launch window.

Quote
“CAPSTONE’s orbital requirements allow for launch opportunities every month,” NASA spokesperson Sarah Frazier told SpaceNews May 2. “NASA, Rocket Lab and Advanced Space are reevaluating the launch period to allow more time for launch vehicle processing.”

In a May 2 presentation at the Interplanetary Small Satellite Conference in San Luis Obispo, California, Tom Gardner, CAPSTONE program manager at Advanced Space, said the company was now targeting a window that opens May 27. He said instantaneous launch windows are available daily until late June.

Quote
Once launched, CAPSTONE will take four months to go into a near-rectilinear halo orbit around the moon, the same orbit NASA plans to use for the lunar Gateway. Its primary mission of testing the stability of the orbit and conducting navigation experiments with the Lunar Reconnaissance Orbiter will last six months, followed by an extended or “enhanced” mission of up to 11 months with additional tests.

When I heard that, I wondered if maybe the host was using the same script from when There and Back Again was scheduled to launch in April, making May "next month." Wouldn't be the only minor verbal flub, when talking about Neutron she described it as "fully reusable" despite it only having first-stage reuse.

NASA, Rocket Lab, and Advanced Space are currently targeting no earlier than May 31, 2022, for the launch of the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, or CAPSTONE, mission. We will continually evaluate the date for the first target launch attempt within the launch period, which extends to June 22.

https://www.nasa.gov/feature/ames/capstone-uses-gravity-on-unusual-efficient-route-to-the-moon

About 20 minutes after launch, the Lunar Photon – carrying CAPSTONE as a payload –will separate from Electron’s second stage at an altitude of 155 miles. After a short coast, Photon’s HyperCurie engine will then periodically ignite to increase its velocity and raise the highest point of its orbit to about 37,000 miles.

About six days after launch, a final ignition will accelerate Photon to 24,500 miles per hour to escape low-Earth orbit on a trajectory into deep space. Within 20 minutes of its final burn completion, Photon will release CAPSTONE into space for the first leg of the CubeSat’s solo flight to the Moon.

The CubeSat will rack up serious mileage hurtling through deep space on its traverse from Earth to the Moon. Assisted by the Sun’s gravity, it will reach a distance of 963,000 miles from Earth – more than three times the distance between Earth and the Moon – before being pulled back towards the Earth-Moon system.

This sinuous track – called a ballistic lunar transfer, or BLT – follows dynamic gravitational contours in deep space. CAPSTONE’s team will calculate the BLT trajectory based on the ever-changing positions of Earth, the Moon, and the Sun.

Expending little energy, CAPSTONE will cruise along these contours punctuated by a series of planned trajectory correction maneuvers. At critical junctures, CAPSTONE’s team at Advanced Space’s mission operations center will command the spacecraft to fire its thrusters to adjust course. Terran Orbital Corporation in Irvine, California, designed and built CAPSTONE and developed novel technology that allows the spacecraft to execute maneuvers while maintaining control of the spacecraft on thrusters only.

When CAPSTONE catches up to the Moon, its approach will be perfectly aligned for NRHO insertion, the crux of its route. While going 3,800 miles per hour, it will perform its delicate, precisely timed propulsive maneuver to enter orbit, like a flying trapeze artist who jumps from one arc to another with a decisive, acrobatic motion.

After deploying CAPSTONE Photon will do its own mission. Photo bomb of moon as its does flyby before heading out into heliocentric orbit. Think plan is to loop back and eventually orbit moon.
RL need to get lot flight time operating Photon in deep space as its next mission is to Venus.

Loop back - from heliocentric orbit? How long would that take?

They quoted 120n for Curie which is monopropellant pressure feed engine used in their kickstand. This Photon is using bipropellant HypeCurie engine, thrust and ISP unknown. Likely to be lot more than 120n.
RL haven't been very forecoming with Hype Curie specs so anybody's guess.

Edit: found ISP 310sec. In Curie thread.

I recall Peter Beck also saying that it has electric pumps. Curie default mode is monopropellant but also can run in bipropellant mode as an option whereas Hyper Curie is bipropellant only.

I was wrong on orbiting. Photon will do a flyby then out way pass moon and loop back to burn up in earth atmosphere. Capstone is 2nd half of video.

Has other interesting stuff on Photon, sounds like a Asteriod mission maybe in pipeline.

Photon dry mass 55kg. Capstone 25kg. Launch mass 300kg, DV >3.2km/s

 250ISP = 3.24km/s.
Not sure what ISP is but being pump feed expect high 200s maybe 300 so probably few more 100m/s of DV in reserve.

That's a pretty low Isp for a vacuum engine. I would have expected around 300 s if they were using electric pump-fed HTP/RP-1. The pressure fed AZ50/N2O4 engine used by the Apollo LM upper stage had 310 s Isp.

For 300ISP DV is 3880m/s, so there is lot left in tank after CAPSTONE is deployed.

If Capstone separation is 3.2km/s with 300ISP Photon has another 900m/s to play with. Should be enough to place it in a lunar orbit.

Fairly minor, but Photon Interplanetary has always been depicted as lacking the stage adapter when in flight. This is in contrast to Photon LEO and the kick stage, which are the stage adapter. I wonder if this means Capstone will move the separation plane to the top of the adapter (optimal propulsive efficiency in minimising third stage dry mass); or separate at the adapter base as is normal for every other Electron launch (maintaining commonality in operations) with Photon subsequently discarding the stage adapter from itself before or just after starting its burn.

NASA, Rocket Lab, and Advanced Space are now targeting June 27, 2022, for the launch of the CAPSTONE mission to the Moon, allowing teams more time for rocket preparations. CAPSTONE’s trajectory design means that the spacecraft will arrive to its lunar orbit on Nov. 13 regardless of launch date within the current period, which runs through July 27.

I get impress RL isn't making any money on Capstone mission, more likely a loss leader project with flight proven(hopefully) deep space Photon bus being the reward. If successful will give NASA and others access to low cost means of doing dedicated deep space missions.

Rocket Lab press release from sometime yesterday:

Rocket Lab Prepares to Launch CAPSTONE Mission to the Moon for NASA (https://www.rocketlabusa.com/updates/rocket-lab-prepares-to-launch-capstone-mission-to-the-moon-for-nasa/)

Quote from: Rocket Lab
Rocket Lab Prepares to Launch CAPSTONE Mission to the Moon for NASA

Rocket Lab will launch a microwave oven-sized CubeSat dubbed CAPSTONE to a never-before-flown orbit around the Moon, blazing a new efficient deep space route that NASA hopes to use for future human spaceflight missions

Long Beach, California. June 23, 2022 – Rocket Lab USA, Inc. (Nasdaq: RKLB) (“Rocket Lab” or “the Company”), a leading launch and space systems company, is preparing to launch a satellite to the Moon for NASA as early as June 27th.   

The launch will take place from Rocket Lab Launch Complex 1 on New Zealand’s Mahia Peninsula. The launch window opens 09:50 UTC on June 27th (21:50 NZST, June 27th). Back-up opportunities are available through July 27th to accommodate potential weather or technical delays to the launch.

Visit NASA.gov/capstone and www.rocketlabusa.com/assets/Uploads/CAPSTONE-launch-press-kit.pdf for full mission information.

Designed and built by Tyvak Nano-Satellite Systems, a Terran Orbital Corporation, and owned and operated by Advanced Space on behalf of NASA, the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) CubeSat will be the first spacecraft to test the Near Rectilinear Halo Orbit (NRHO) around the Moon. Researchers expect this orbit to be a gravitational sweet spot in space – where the pull of gravity from Earth and the Moon interact to allow for a nearly-stable orbit – allowing physics to do most of the work of keeping a spacecraft in orbit around the Moon. NASA has big plans for this unique type of orbit. The agency hopes to park bigger spacecraft – including the lunar-orbiting space station Gateway – in an NRHO around the Moon, providing astronauts with a base from which to descend to the lunar surface as part of the Artemis program.

CAPSTONE will be launched to an initial low Earth orbit by Rocket Lab’s Electron launch vehicle and then placed on a ballistic lunar transfer by Rocket Lab’s Lunar Photon spacecraft bus. Unlike the Apollo lunar missions of the 1960s and 70s, which took a free return trajectory to the Moon, this fuel efficient ballistic lunar transfer makes it possible to deploy CAPSTONE to such a distant orbit using a small launch vehicle. Standing at just 59 feet tall, Electron is the smallest rocket to attempt a launch to the Moon.

Rocket Lab founder and CEO, Peter Beck, said: “This is Rocket Lab’s most ambitious mission yet. For the first time, Electron and Photon are going far beyond standard mission profiles, pushing the envelope of what’s possible for interplanetary small spacecraft missions. No spacecraft has ever been placed in this type of orbit, so it’s exciting to be working with such innovative partners in NASA, Advanced Space, and Terran Orbital to make this ground-breaking mission possible.”

The launch will be broadcast live from approximately 45 minutes prior to lift-off at www.rocketlabusa.com/live-stream and www.nasa.gov/multimedia/nasatv/#public

Rocket Lab has indicated that they will have a webcast on their own YouTube channel.

My guess is that RL and NASA will be simulcasting the same livestream, and that it will be combined RL + NASA.  So hopefully it will only be half-terrible. :)

Now that’s curious
The times are rounded to five minute intervals but the overall progression is closer to four minutes per day.
This is close to the rotation rate of the Earth-Sun system, not the Earth-Moon system.
That and the invariant arrival date illustrate what odd, fascinating constructs these Ballistic Lunar Transfer trajectories are.

Once Electron has launched CAPSTONE to LEO, It's Photon's show! Over 6 days, Photon will perform several precise orbit raising maneuvers to set CAPSTONE on a Ballistic Lunar Transfer.

CAPSTONE en Route to the Moon After Successful Launch

Abby Tabor Posted on June 28, 2022 7:40 am

NASA’s Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) mission is in space on the first leg of its journey to the Moon. CAPSTONE launched at 5:55 EDT (09:55 UTC) on Rocket Lab’s Electron rocket from the Rocket Lab Launch Complex 1 on the Mahia Peninsula of New Zealand, Tuesday, June 28. 

Over the next six days, the engine of the Lunar Photon – the spacecraft carrying CAPSTONE as a payload – will periodically ignite to accelerate beyond low-Earth orbit and release CAPSTONE on the next phase of its journey to the Moon.

Rocket Lab did not give the mission a name.

I wonder whether this was at NASA's behest, since they wanted to associate this as "the first mission of Artemis" and not a standalone thing.

I also wonder if NASA is why booster reuse wasn't even discussed on the livestream. I understand that this particular mission had parameters which precluded reuse, but not even addressing it makes me think perhaps they didn't want to contrast too sharply with the disposable SLS sitting behind the NASA presenter.

They've stated a few times mission needed every ounce of Electron performance.  Which was why there were no camera feeds from LV.

Even if they had performance to spare recovery by helicopter would be off cards as it fly's due east out of range of helicopter.

Sure, I wasn't expecting this mission to have reuse, especially considering they may still be working through upgrades from the last mission, which did attempt a mid-air capture. But I think if this were a "normal" mission, we'd have heard some updates on reusability, including what was learned from the previous mission and an explicit statement confirming what you said (which, again, I totally believe is true).

Although, side-note, my impression regarding the cameras and telemetry was that they were recording more pieces of information about this launch than would normally be done (since minor changes now could have major impacts on the lunar orbital insertion months from now), so they didn't have the download bandwidth to carry video too. Not that the weight limits were so strict they needed to remove the cameras.

Edit: Peter Beck suggests that both bandwidth and mass were reasons to remove the cameras.

Here is the available launch telemetry from the NASA CAPSTONE webcast.

1. Unfortunately, the first 67 seconds of telemetry was omitted from the webcast, so I'm not able to infer downrange distance.
2. However, both the X and Y components of the velocity vector can be deduced. The relatively high number of decimal places in the displayed altitude reduces the noise in these components compared to other webcasts.

New TLEs for CAPSTONE show it in a slightly less elliptical orbit of 250 x 1043 km rather than 220 x 1075 km. This appears to reflect improved measurement rather than an actual change.

 - Ed Kyle

Yes, if you ignore “little perturbations” like the Sun and the Moon.
A pitched baseball is in a “highly elliptical orbit of the Earth” if you ignore the atmospheric drag and the impact at h=0.
That statement is not false but without meaning.

PS. I admire greatly Rocketlab’s ability to dynamically improve the trajectory like combining two “manoevres”  into one.
THAT’s New Space!
Let’s keep making progress.

Space is busy and getting busier. It’s why we designed Electron to deploy satellites sustainably, without leaving large rocket parts in orbit. For #CAPSTONE, Electron’s second stage deorbited within 24 hours of launch - our fastest time yet - avoiding it becoming space junk.

CAPSTONE Leaves Earth Orbit, Headed to the Moon

Sarah Frazier Posted on July 4, 2022 4:44 am

The Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) has left low-Earth orbit and started its solo journey to the Moon.

Following its launch on June 28, CAPSTONE orbited Earth attached to Rocket Lab’s Photon upper stage, which maneuvered CAPSTONE into position for its journey to the Moon. Over the past six days, Photon’s engines fired seven times at key moments to raise the orbit’s highest point to around 810,000 miles from Earth before releasing the CAPSTONE CubeSat on its ballistic lunar transfer trajectory to the Moon. The spacecraft is now being flown by the teams at Advanced Space and Terran Orbital.

Now, CAPSTONE will use its own propulsion and the Sun’s gravity to navigate the rest of the way to the Moon, a four-month journey that will have CAPSTONE inserting into its near rectilinear halo orbit (NRHO) around the Moon on Nov. 13. The gravity-driven track will dramatically reduce the amount of fuel the CubeSat needs to get to its target orbit around the Moon.

In the coming days, you can follow CAPSTONE’s journey live using NASA’s Eyes on the Solar System interactive real-time 3D data visualization, riding along virtually with the CubeSat with a simulated view of our solar system.

RL plan to take few close up photo's of moon with Photo as it flys pass. Last I heard it follow similar path to Capstone and orbit back to Earth for disposal in few months.

NB RL havn't been very for coming about what happens to Photon from how on, just snippets from interviews with RL staff.

I wonder if they'll attempt to slingshot it into a heliocentric orbit. Would be a great opportunity to practice long-term and long-distance communications with Photon, in preparation for interplanetary missions.

From LinkedIn:  MISSION SUCCESS!

Lunar Photon has deployed the CAPSTONE satellite to a ballistic lunar transfer. With Rocket Lab’s role in the mission now complete, CAPSTONE has started its solo journey to the Moon.

This is a monumental mission for our team, for NASA - National Aeronautics and Space Administration, for our mission partners and for the future of space exploration. CAPSTONE is the very first mission of NASA’s Artemis program – humanity’s return to the Moon is underway thanks to Photon and Electron.

Missed the CAPSTONE deployment webcast? Watch here: https://lnkd.in/d5GDwmPe


Is now a good time to mention we have launch and spacecraft operations roles open? Join the team and it could be you in mission control when we go to Venus, Mars and beyond. https://lnkd.in/dnVPDZgM

This amateur satellite tracker has also noticed the lack of a downlink signal from the satellite when he attempted to observe it, and the subsequent DSN activity:

Well, if none of the 20 kg reserve propellant was used, I estimate a delta-V of 2866*ln(1+20/55) = 889 m/s of delta-V is available! A direct injection to NRO is 428.5 m/s. As CAPSTONE is using ballistic Lunar transfer (BLT), it only had 200 m/s, of which 20 to 60 m/s is for the BLT. I think this is definitely the backup plan if CAPSTONE doesn't work. Of course, Lunar Photon would require its communications systems to be able to work at Lunar distances.

I didn't say it will do something relative to CAPSTONE. CAPSTONE is set to explore the unique lunar orbit for the Gateway. Photon, on the other side, tests the hardware of Rocket Lab to travel beyond LEO. It's important, because Peter Beck wants to go to Venus. The only thing I did was disputing your claim that it's "just an upper stage". It's more than that. A lot more.

Photon is like the old Agenas: a satellite bus and upper stage in one. Photon would not be able to test CAPS - lacking the radio for that particular function - but it would still be able to enter NRHO and monitor orbit stability (using ground-based positioning). Not a full CAPSTONE replacement, but able to accomplish a portion of the mission.

Whether it can get to NRHO at this point would depend on how soon a decision to do so would need to be made with whatever delta V it has remaining, and how soon a contract could be drafted with Rocket Lab to do so (since they have their own mission they want to accomplish with Photon that they would need to cancel). Getting to NRHO would be a solid 'maybe', but getting a contract ready in time seems unlikely.
If a constraint is added that nothing would happen until efforts to recover CAPSTONE (if indeed there is a problem in the first place, which is not confirmed) had been deemed as failed, then using Photon as a NRHO demonstrator seems even less likely.

Photon is an upper stage- but like the old Agena it is more than that.

Photon is being marketed as a host platform for  customer payloads, and RocketLab has had success in this regard.
They have ambitions to extend Photon for interplanetary and deep-space missions as well.

To discount the Photon as merely an upper stage isn't really correct, though for this particular mission it is true.  RocketLab completed its launch service on this program when CAPSTONE separated from the Photon.

Photon should have DV and comms to enter NRHO but designing course correction burns isn't 5 minute job. It was on same trajectory as Capstone but RL may have changed that by now to achieve close flyby of moon for photo shot.

Be surprised if RL, NASA and Capstone team aren't seriously considering this option now.

Looks like I'm incorrect.  CAPSTONE has an IRIS for primary communications.
I'm not sure what radio is used for S-band communications.

How?  It just an upper stage.

It's an upgraded upper stage that can function on its own like a satellite.

A meaningless point. Even if there were another satellite on the mission, it doesn't mean it would be able to do anything relative to CAPSTONE.

I didn't say it will do something relative to CAPSTONE. CAPSTONE is set to explore the unique lunar orbit for the Gateway. Photon, on the other side, tests the hardware of Rocket Lab to travel beyond LEO. It's important, because Peter Beck wants to go to Venus. The only thing I did was disputing your claim that it's "just an upper stage". It's more than that. A lot more.

No, still just an upper stage

This is a good time to dispute a statement from Jim.
Actually, it’s not apparent why he should insist on something so semantic.
There is a gradual transition from upper stage to satellite. Having subsystems not needed to get the payload to orbit, is much of what I would include in that. Just look at some of the rideshare OTV’s, most of which release some payloads but keep others snd provide services to them like attitude control.
Take solar cells instead of batteries.
One (Jim?) could argue that the Capstone launch took place over a week, so solar cells were just a more efficient way to power an upper stage for the required duration.
But if these are included with, say, momentum wheels to supplant ACS thrusters, and higher power comms to communicate from the last apogee before TLI, it’s a pretty capable satellite.  It might be used solely as an upper stage, and one could keep that designation even if it flies some long, complex trajectory after releasing its payload, but it’s sure looking like a spacecraft.
Should it depend on what they do with it later, like possibly returning photos of the Moon?

Read about CAPSTONE comms issues:

http://spaceref.com/missions-and-programs/nasa/nasa-capstone-mission-experiences-comms-issue.html (http://spaceref.com/missions-and-programs/nasa/nasa-capstone-mission-experiences-comms-issue.html)

Does this in any way reflect on Rocket Lab's portion of the mission? Or is this some software problem on the CAPSTONE payload?

Isn't CAPSTONE flying a RocketLab provided Frontier Lite radio (Same as what's on the Photon?)
RocketLab is a significant component supplier aside from being a launch services and launch vehicle provider.

Looks like I'm incorrect.  CAPSTONE has an IRIS for primary communications.
I'm not sure what radio is used for S-band communications.
https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=CAPSTONE (https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=CAPSTONE)

The "telecomunications Information for CAPSTONE" page has no other information present.

The RL press kit notes the IRIS as well:
https://www.rocketlabusa.com/assets/Uploads/CAPSTONE-Press-Kit3.pdf (https://www.rocketlabusa.com/assets/Uploads/CAPSTONE-Press-Kit3.pdf)
(Page 10)

This brings up another question:
What is the advantage of having the Capstone microsat built, instead of adding functionality to Photon? 
Beyond adding the IRIS, what else would be needed for Photon to demonstrate the NRHO?
Could RL even been asked to add IRIS to this Photon as backup to Capstone?

It's a fuzzy line to be sure...
A free-flying photon that goes on to do an extended mission, doing maneuvers, communicating, and possibly returning additional observations or data, is most certainly not "just an upper stage."

It deployed a spacecraft as part of a launch, so clearly Photon is an upper stage in the classical sense.

The rest looks like an respectable small upper stage that has been transforming into a hosted payload carrier, tug, and interplanetary mission platform. Just like RL has said it would.

You're missing the point Jim was making. It's not that Photon doesn't have satellite-like functionality, it's that for this particular mission and payload Photon was just serving an upper stage. Photon has already separated from CAPSTONE, and thus there is nothing Photon can do to resolve the current issues with CAPSTONE.

Sorry, but that’s not an answer to my question.
It can enter the orbit but it cannot communicate with LRO to do the navigation experiment.

The question is why did NASA chose not to add that capability to Photon, which was flight proven to a great degree?
It seems much simpler than building Capstone.

This is somewhat like the discussion in the Psyche thread.
The mission is having problems with its imager functioning at the cold operating temperature due to distortion of the Primary mirror.
The quote is that the NASA team is trying to solve this by using “different materials and bonding”.
This was solved decades ago by specifically avoiding disparate materials and all bonding.
NASA seems to always want to “reinvent the wheel”.
Augmenting Photon seems a less risky evolution.

Frontier Lite- which I still believe is the radio on this Photon- is similar to the IRIS. 

As I  understand it, RocketLab has miniaturized/cost-reduced/performance enhanced the APL Frontier deep space radio.  The Frontier is a really awesome radio, so this would be a great way to demonstrate what the Frontier Lite can do (If I'm not wrong again about what radio is in the Photon)

What RL could do with this photon in the extended mission is probably driven more by the capabilities of their ground station(s) at this point.

And to directly address Comga's question:  Although the Frontier Lite is an SDR, I do not believe that it has firmware available to facilitate the communication with LRO, and even if it did then there would need to be a way to support that firmware along with the primary communication back to the RL ground segment.   Because the Frontier is a fully deep space- capable radio with ranging support, perhaps there are meaningful navigation capabilities that could be demonstrated still in an extended mission.  The big limitation on the Photon side will be transmit power and available antennas.

Correct, Photon won't be able to do the positioning demonstration with LRO. But it could demonstrate NRHO and fuel usage to maintain that orbit. Putting Photon into NRHO would be doing something desperate to salvage some of the mission, not being able to complete it entirely.

...

The CAPSTONE mission was awarded in September 2019, Photon did not perform a demonstration flight until June 2020, so no, a flight proven Photon was not an option for it.

Right
NASA interfering with the free market
Rocketlab is a commercial supplier who has developed launch and orbital capabilities on their own, capabilities which NASA needs.
Yet NASA is finding a much less capable company to compete with them.
It adds risk for NASA, and disadvantages entrepreneurial development.
This is also happening with NASA buying launces on small, unflown rockets and some groups efforts to fund an alternative lunar landing system.

So at this time CAPSTONE isn't talking to the ground, it could be dead, it might be confused, it might wake up any time.
Now I'm wondering whether Photon can enter NRHO and achieve some of the mission goals. It has the propellent, but lacks the avionics needed to talk to  LRO.

A meaningless point. Even if there were another satellite on the mission, it doesn't mean it would be able to do anything relative to CAPSTONE.
Photon is like the old Agenas: a satellite bus and upper stage in one. Photon would not be able to test CAPS - lacking the radio for that particular function - but it would still be able to enter NRHO and monitor orbit stability (using ground-based positioning). Not a full CAPSTONE replacement, but able to accomplish a portion of the mission.

Whether it can get to NRHO at this point would depend on how soon a decision to do so would need to be made with whatever delta V it has remaining, and how soon a contract could be drafted with Rocket Lab to do so (since they have their own mission they want to accomplish with Photon that they would need to cancel). Getting to NRHO would be a solid 'maybe', but getting a contract ready in time seems unlikely.
If a constraint is added that nothing would happen until efforts to recover CAPSTONE (if indeed there is a problem in the first place, which is not confirmed) had been deemed as failed, then using Photon as a NRHO demonstrator seems even less likely.
Photon should have DV and comms to enter NRHO but designing course correction burns isn't 5 minute job. It was on same trajectory as Capstone but RL may have changed that by now to achieve close flyby of moon for photo shot.

Be surprised if RL, NASA and Capstone team aren't seriously considering this option now.


Somebody on twitter said solar arrays didn't deploy in which case batteries maybe dead by now.

Peter Beck did confirm Photon could enter NRHO but comms to earth would be limited. Could still acheive some of Capstones objectives ie station keeping.  Lot depends on if Photon hasn't alter course for its secondary mission. Not clear if Beck made this statement before or after issues with Capstone spacecraft.

Further Details on Communications Issues with NASA’s CAPSTONE

Sarah Frazier Posted on July 5, 2022 8:00 pm

NASA’s Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) experienced communications issues following its deployment on July 4. This is an update on the spacecraft health and efforts to regain contact between CAPSTONE and NASA’s Deep Space Network (DSN). 

Following CAPSTONE’s initial deployment on July 4, the spacecraft successfully deployed solar arrays, was stabilized, and began charging its onboard battery. CAPSTONE’s propulsion system was also readied for the spacecraft’s first maneuver.  CAPSTONE made initial contact with the DSN ground station in Madrid, Spain, followed by a partial contact with the Goldstone ground station in California. From these contacts, mission operators have been able to determine CAPSTONE’s approximate position and velocity in space. 

As a result of the communications issues, CAPSTONE’s first trajectory correction maneuver – originally scheduled for the morning of July 5 – has been delayed. This maneuver is the first in a series that are designed to make small corrections to increase the accuracy of the transfer orbit to the Moon, and the spacecraft remains on the overall intended ballistic lunar transfer while awaiting this trajectory correction. 

Teams are working to resolve CAPSTONE’s communications issues.

But maybe I'm not understanding what "free market" means to you.

We are veering off topic, but the MAIN goal of Capstone was to demonstrate the NRHO for Artemis.
NASA’s secondary purpose of the SST SBIR was to stimulate new entrants into the market.
Unless things improve, NASA will have failed at the main goal.
It’s not clear how well they will have done on the secondary goal of fostering a startup if their first spacecraft fails while being front and center for everyone paying attention to Artemis.
This was not a self funded demo like the early launches of Falcon 1 or Electron.
If it’s really important, you should go with the proposal with the highest probability of success, in your best judgment.


In hindsight, a backup deep space interconnect on Photon could have been cheap insurance.

So you can not design your spacecraft depends on special features of a particular launch vehicle.

I think the suggestion is that separate from the contract to Advanced Space to build CAPSTONE, NASA's contract with Rocket Lab could have included a few upgrades to Photon to make it more serviceable as a secondary backup payload should CAPSTONE fail. Of course, "include a whole dissimilarly-redundant second spacecraft to cover the primary mission" isn't exactly Standard Operating Procedure in space missions, so I can see why NASA wouldn't have thought of it. Plus the full range of Photon's capabilities (and how close it was to already being that second spacecraft) may not have been known far enough in advance for such a contract modification anyway.

Failure of Capstone satellite is far from total mission failure.
This Photon bus is basis of ESCAPADE mission to Mars. So far this side of the tech demo is working as planned, still few months to go before they can say its a success.

I think the suggestion is that separate from the contract to Advanced Space to build CAPSTONE, NASA's contract with Rocket Lab could have included a few upgrades to Photon to make it more serviceable as a secondary backup payload should CAPSTONE fail. Of course, "include a whole dissimilarly-redundant second spacecraft to cover the primary mission" isn't exactly Standard Operating Procedure in space missions, so I can see why NASA wouldn't have thought of it. Plus the full range of Photon's capabilities (and how close it was to already being that second spacecraft) may not have been known far enough in advance for such a contract modification anyway.
The Photon/Electron stack was operation right on the edge of performance to fly this mission (e.g. stripping off extra mass like on-board cameras to gain margin). Putting extra equipment onto Photon would have meant removing that equipment from CAPSTONE to make up the mass budget. That would then be an entirely new mission (hosted payload on Photon rather than independent cubesat).

CAPSTONE Mission: 05 July 2022 Update

Jul 5, 2022

On July 4, 2022, CAPSTONE (Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment) separated successfully from the launch vehicle and is heading to the Moon on behalf on NASA. The Advanced Space Operations Center and the Mission Operations Center at Terran Orbital are in full swing beginning mission operations, the DSN, and mission partners. We are proud of the hard work the operations team has been doing.

During commissioning activities an anomaly was experienced related to the communication subsystem; the operations team is actively working this issue with the Deep Space Network and determining the best next steps.

As a result of this anomaly, the first trajectory correction maneuver – originally scheduled for the morning of July 5th – has been delayed. This maneuver is designed to more accurately target the transfer orbit to the Moon. This maneuver is the first in a series that are designed to make small corrections to increase the accuracy of the transfer orbit to the Moon. The spacecraft remains on the overall intended ballistic lunar transfer (BLT) while this targeting maneuver is delayed.
One of the benefits of the BLT, the designed trajectory, is its robustness to delays such as this.
The mission transfer approach and system margins provide time to resolve and understand this anomaly before proceeding with the first trajectory correction maneuver.
At the time of publication, the CAPSTONE spacecraft is currently approximately 285,000 km from Earth (~8 times GEO) on its planned ballistic transfer orbit to the Moon.

Spacecraft was commissioning nominally for the first 11 hours.
Spacecraft was deployed successfully from the launch vehicle.
Spacecraft successfully deployed solar arrays, achieved three-axis stabilization, and entered a battery charging mode.
Spacecraft successfully executed Earth-pointing mode, communicated with DSN stations in Madrid Spain and the operations team began check-out and commissioning of the spacecraft.

The operations team was able to determine spacecraft state (position and velocity) and design initial trajectory correction maneuver.

Propulsion system was commissioned and prepared for the first trajectory correction maneuver.

The CAPSTONE mission team has been working around the clock and through the holiday weekend to support this important mission. With CAPSTONE utilizing the BLT, it will take four months to reach the planned Near Rectilinear Halo Orbit (NRHO) around the Moon. As further details emerge, we will make them available.

Is the radio on Photon not compatible with DSN? I was wondering about Peter Beck's comment that comms is going to be the hardest thing for Photon.

The radio being compatible with DSN is different than the mission being DSN-capable. 

The spacecraft would have needed compatibility testing with DSN pre-launch, which would not have been done for a mission not planning to use DSN.

Further, the ground segment (mission operations center) would also need to have been prepared to make use of the DSN.  That involves setting up the required network (data and voice) connectivity to DSN, and again preparing for and demonstrating compatibility pre-launch. 

When performing passes with DSN, there is coordination required as each station on each pass will need to follow a briefing and prepare the station equipment for the upcoming contact. 

With none of that completed, it would be extremely difficult (and not quickly possible) to use DSN for mission communications.

Not impossible, but almost certainly not going to happen in time for any near-term mission communications.

Following Communications Recovery, NASA’s CAPSTONE Prepares for First Maneuver

Following communications issues, mission teams for NASA’s Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) have re-established contact with the spacecraft through NASA’s Deep Space Network. Data received from CAPSTONE shows that the spacecraft is in good health and operated safely on its own while it was out of contact with Earth.

Teams are preparing to carry out CAPSTONE’s first trajectory correction maneuver – which will more precisely target CAPSTONE’s transfer orbit to the Moon – as early as 11:30 a.m. EDT on July 7. As originally planned, CAPSTONE will arrive to its lunar orbit on Nov. 13. 

The CAPSTONE team is still actively working to fully establish the root cause of the issue. Ground-based testing suggests the issue was triggered during commissioning activities of the communications system. The team will continue to evaluate the data leading up to the communications issue and monitor CAPSTONE’s status.

The mission team, led by Advanced Space, initially re-established contact with CAPSTONE at 9:26 a.m. EDT on July 6. The signal confirmed that CAPSTONE was in the expected location, as predicted based on data from CAPSTONE’s initial contacts on July 4. The team started recovery procedures and began receiving telemetry data from the spacecraft at 10:18 a.m. EDT.

Mission Team Determines Cause of Communications Issues for NASA’s CAPSTONE

After a thorough review, teams have determined what led to CAPSTONE’s communications issue that began on July 4. 

During commissioning of NASA’s CAPSTONE (short for Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment) spacecraft, the Deep Space Network team noted inconsistent ranging data. While investigating this, the spacecraft operations team attempted to access diagnostic data on the spacecraft’s radio and sent an improperly formatted command that made the radio inoperable. The spacecraft fault detection system should have immediately rebooted the radio but did not because of a fault in the spacecraft flight software.

CAPSTONE’s autonomous flight software system eventually cleared the fault and brought the spacecraft back into communication with the ground, allowing the team to implement recovery procedures and begin commanding the spacecraft again. 

While CAPSTONE was out of contact with Earth, the spacecraft autonomously maintained its orientation to keep its antenna pointed towards Earth and allow the solar panels to keep its battery charged. CAPSTONE also used its thrusters to perform a standard maneuver to dump excess momentum from its reaction wheels, which are internal wheels that help the spacecraft rotate and point itself. 

The mission operations team conducted CAPSTONE’s first trajectory correction maneuver at approximately 11:30 a.m. EDT today. Teams are currently reviewing the data to ensure the maneuver was successful, and an update will be provided later. This maneuver will more precisely target the spacecraft’s transfer orbit to the Moon.

NASA’s CAPSTONE Pulls Off First Targeting Maneuver on Journey to the Moon (https://blogs.nasa.gov/artemis/2022/07/07/nasas-capstone-pulls-off-first-targeting-maneuver-on-journey-to-the-moon/?utm_source=TWITTER&utm_medium=NASAAmes&utm_campaign=NASASocial&linkId=172337501)


NASA’s CAPSTONE successfully completed its first trajectory correction maneuver, which started at 11:30 a.m. EDT Thursday. This is the first in a series of thruster burns over the next few months to more accurately target CAPSTONE’s transfer orbit to the Moon. The maneuver lasted just over 11 minutes and changed the spacecraft’s velocity by about 45 miles per hour (about 20 meters per second). CAPSTONE’s next trajectory correction maneuver is targeted for Saturday, July 9. 


CAPSTONE is now about 289,000 miles from Earth, beyond the orbit of the Moon. CAPSTONE will loop back around and arrive to its lunar orbit – called a near rectilinear halo orbit, or NRHO – Nov. 13. CAPSTONE will fly in the NRHO for at least six months to study the dynamics of the orbit, which is the same one intended for Gateway, a lunar space station for science and human exploration under Artemis. 


Two technology demonstrations on CAPSTONE could allow future spacecraft to navigate near the Moon without as much tracking required from Earth.

Great to hear they found the cause of the problem. Standard practise is to always verify any commands to be sent on a model of the spacecraft, before you send the commands. Sounds like this wasn't done properly.

Note: I have no direct knowledge of the CAPSTONE mission. 

It sounds like they may have sent a debug or other special command to the radio.  It's possible that there is a "generic" command for the avionics to communicate with a complex subsystem (in this case the IRIS radio.)  In other missions that I've worked on, a supplier has revealed additional commanding or telemetry from such a subsystem when in flight and having something go funny (in this case, odd behavior in the ranging data that DSN was seeing.)  Having such a generic commanding capability is a double edged sword- very powerful and very dangerous.

One of the really big dangers in mission operations is sending such a command in near-real time without good verification.

In my own experience, missions would have have sent that command on a testbed (usually a flatsat) BEFORE doing it in flight.   

I wonder if there is a high fidelity hardware in the loop simulator available for this mission where that might have been caught.

Also interesting and perhaps more disturbing to me is that when the faulty commanding took the radio offline, the expectation was that onboard fault protection would have immediately rebooted the radio.  That didn't happen, and the release mentions that a different FSW defect prevented that from happening.  That's also a bad day- and likely a further test/verification (shortcoming) failure.  Perhaps they then spent time commanding in the blind and perhaps waiting/hoping that additional fault protection would fire and restore radio operation- which is what appears to have happened. 

I can sympathize- this kind of verification is really hard to do with full coverage- especially if you have a very complicated and dynamic subsystem where not every conceivable command may even be known in advance.

Based on the timeline and what we saw on DSN Now, they did a ton of blind commanding, got nothing, and then got it back 1-2 days later.  Sounds like a command loss timer expiration to me.

Glad it worked.  I've been doing spacecraft software for decades and I can sympathize completely with how they must have felt just after sending that bad command...

Depends on your definition of high-fidelity, but I wouldn't try to do anything at any price without some kind of a flatsat for testing.  But there could have been fidelity issues from cost-cutting, sure.

I've seen higher budget smallsat missions in the 12U range with really good full fidelity simulators.
I've also seen missions where the only avaialable hardware was the actual flight (or protoflight) hardware. 

I could easily see where the only procured hardware would have been the flight IRIS radio and perhaps there isn't a spare/EM/Emualtor IRIS around in a testbed.

BTW, upthread I wondered about whether or not there was a Frontier series radio onboard, before I read the press kits and realized it was an IRIS. 

I still have reason to believe that there may be a Frontier radio onboard, though it isn't the primary (DSN) radio.  I haven't seen any description about what CAPSTONE is using for the space-to-space radio to communicate with LRO.  I don't believe there is firmware for an IRIS to do that. 

If there are both IRIS and Frontier-S radios on CAPSTONE, that's some pretty darned capable hardware, but it does leave one to specualte on whether or not there is a testbed available for these- based on available budget information for the mission. 

Even if it isn't a Frontier-S, there is some other radio onboard to communicate with LRO and that's not yet been disclosed as far as I know.

It will be VERY interesting to learn more as the mission progresses.

NASA’s CAPSTONE Updates Maneuver Schedule on Journey to Moon (https://blogs.nasa.gov/artemis/2022/07/09/nasas-capstone-updates-maneuver-schedule-on-journey-to-moon/)



The team for NASA’s Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) is standing down from the trajectory correction maneuver scheduled for July 9 to perform additional analysis on the spacecraft’s performance. The mission team will make a determination whether the maneuver is still needed at this time, and updates will be provided. 


Trajectory correction maneuvers are thruster burns used to clean up expected variation in CAPSTONE’s orbit and more accurately target its path to the Moon. The maneuver scheduled for July 9 was to be part of CAPSTONE’s first series of trajectory corrections. CAPSTONE’s first trajectory correction maneuver on July 7 achieved about 90% of the objectives for this series of maneuvers. 


CAPSTONE remains healthy and on track to arrive to its lunar orbit on Nov. 13. Read more from Advanced Space, which owns and operates CAPSTONE on behalf of NASA.

Rocket Lab got $9.95 million for the launch. The cost for the CAPSTONE itself was $13.7 million.

There's also a ~$6 million budget for mission operations, the total is around $30 million.

"By the way, why does it take four months for CAPSTONE to get to the moon instead of four days like the Apollo missions?"


The path they are following is extremely fuel-efficient.  If you go fast you have to slow down a lot at the other end.  The slower you go the less you need to push at the beginning and the less you have to slow down at the other end.  There are other aspects to it but this is a simple way to consider it.

Also Apollo couldn't go slowly and efficiently because of the need to keep the crew alive - has to be quick.

NASA’s CAPSTONE Executes New Maneuver, Further Pinpoints Path to Moon

NASA’s Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) successfully completed its second trajectory correction maneuver starting at about 11:30 a.m. EDT Tuesday.

CAPSTONE will perform several such maneuvers during its four-month-long journey to lunar orbit to refine its trajectory to the Moon, with the next one targeted for late July. CAPSTONE is taking a long but fuel-efficient route to the Moon, flying about 958,000 miles (1.54 million kilometers) from Earth before looping back around to its near rectilinear halo orbit.

Hey, you get what you pay for. And that's a good thing -- having multiple price points to the Moon is better than just the expensive-but-fast option.

This is using same commercial ground stations they use for LEO missions. Listen to this interview for more info.  Peter also talked about Hypercurie ISP, hit 320 but it wasn't clear if this was designed sustained ISP, sounds like might be closer to 310. Still very respectful for such a small engine using storage propellants.

Another Success with CAPSTONE Lunar Mission
Jul 27, 2022 | CAPSTONE Mission

Spacecraft remains on target to test navigation technology and lunar operations to support NASA’s Moon missions under Artemis programs

It is hard to believe we launched CAPSTONE almost a month ago. We have encountered many variables that have kept this mission exciting, and the mission operators have been active. The Advanced Space Astrodynamics and Navigation Engineers have been busy for years leading up to this and just as busy this last month as CAPSTONE flies. An assumption may be that a small satellite means less work but in actuality the effort is just as great if not more so. Small satellites with small budgets and size restrictions require more creativity and calculated steps to ensure precision and execution through the process.

Monday’s trajectory correction maneuver (TCM) was conducted in two stages to allow the navigation software to recalibrate in order to make the full burn more accurate. The first portion of the maneuver lasted 11 minutes and the following portion was 15 minutes. This TCM performed a small accommodation to align the outbound trajectory from launch to the inbound trajectory to the near rectilinear halo orbit (NRHO), the intended orbit for the Gateway.

“Our team has been showcasing unique expertise and improving our tools and knowledge since the beginning of the CAPSTONE mission 2.5 years ago. Each stage of the mission validates these capabilities and demonstrates the ability of our team to optimize and support operations in challenging environments such as cislunar space,” said Bradley Cheetham, Advanced Space chief executive officer and CAPSTONE principal investigator. “Our team is driven, resilient, and dedicated to supporting the sustainable exploration, development, and settlement of space through all phases of the mission and in the face of challenges and adversity.”

State-of-the-art technology will be used by the small satellite beyond low earth orbit to navigate the spacecraft. Once at the NRHO, CAPSTONE will demonstrate the peer-to-peer navigational technology advancement of the Cislunar Autonomous Positioning System (CAPS) developed by Advanced Space. This system will revolutionize the future of spacecraft navigation. Not only will the dependency of Earth communications systems to determine the location of the spacecraft be reduced but mission costs from utilizing those systems will also become reduced.

This week’s maneuver confirmed the microwave-size spacecraft remains on its ballistic lunar transfer (BLT) to the Moon. The Advanced Space team continues to conduct flight dynamics analyses, orchestrate their designed maneuvers, and maintain spacecraft navigation with the Terran Orbital team commanding spacecraft activities. Operations includes exchanging data with NASA’s Deep Space Network and working with component builders – Stellar Exploration for propulsion and Space Dynamics Laboratory for the radio system.

At the completion of the TCM, CAPSTONE was 1,250,796 km from Earth and moving at 595 mph (267 m/s). CAPSTONE is still scheduled to reach the target NRHO in four months on November 13th.

NASA’s CAPSTONE Executes Third Maneuver on Track to the Moon

Gianine Figliozzi Posted on July 27, 2022 4:19 pm

NASA’s Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) successfully completed its third trajectory correction maneuver (TCM) on Monday. CAPSTONE is taking a long but fuel-efficient route to the Moon, flying about 958,000 miles (1.54 million kilometers) from Earth before looping back around to its near rectilinear halo orbit (NRHO).

 At the completion of the maneuver, CAPSTONE was about 780,000 miles (1.25 million kilometers) from Earth and was moving at about 595 miles per hour (about 267 meters per second). CAPSTONE will perform several such maneuvers during its journey to lunar orbit to refine its trajectory to the Moon.

CAPSTONE remains on track to arrive to its lunar orbit on Nov. 13.

My vote is swinging out to heliocentric, to test the comms and other systems in deep space prior to the 2023 Venus mission. But they may not have the propellant margin for that.

While does remove space debris it now creates lunar debris, best to dispose of it into deep space or earth atmosphere.

"“we’ll have a crack at doing something cool with it and see how far into the solar system we can get with it.”"

So not a moon impact! 

"best to dispose of it into deep space or earth atmosphere"

But no, 'deep space' means heliocentric orbit, which re-encounters the Earth-Moon system periodically (think Apollo 12 SIVB) and therefore remains an impact hazard.  And Earth atmosphere disposal is (a) a hazard to other satellites on approach, (b) dumps stuff into the atmosphere which we used to ignore but is now being taken more seriously as a problem), and (c) if it reaches the surface it's another impact hazard.  Putting it on the Moon where there is no atmosphere or biosphere and where the debris may one day serve as input for lunar manufacturing or a subject for various research projects (seismic studies to organics survival) is by far the best thing.

No matter... Photon is going elsewhere.

CAPSTONE Mission: 12 September 2022 Update
Sep 12, 2022 | CAPSTONE Mission

On September 10th we provided an update on the CAPSTONE mission and below are updated details on the situation.

This is a dynamic operational situation, and the below details are provided based on our best knowledge at time of release. Updates to below information will be provided as we learn more.

During or shortly after the third trajectory correction maneuver (TCM-3) on September 8th, the spacecraft suffered an anomaly that resulted in the vehicle attitude rates growing beyond the capacity of the on-board reaction wheels to control and counter. The vehicle was attempting to communicate with the ground for approximately 24 hours before any telemetry was recovered. At the point of recovery, the spacecraft was not in a stable configuration, it was not power positive, and the system was experiencing periodic resets.

Navigation data collected after the anomaly suggests that the maneuver was completed or nearly complete when the anomaly occurred. This means the spacecraft remains on the intended trajectory and on course to the near rectilinear halo orbit at the Moon.

After the planned TCM-3 maneuver, the spacecraft did not return to ground communications as expected which provided the first indication that there might be an issue.

Working with limited data, the combined operations team determined it was prudent to declare an operational emergency Thursday evening, September 8th. From this point forward, the teams at the NASA Deep Space Network, Terran Orbital, and Advanced Space have been working around the clock to work the problem, understand what is happening on the spacecraft, and identify options to recover the spacecraft to normal operations.

Rapid response enabled by the Deep Space Network support and quick thinking by the team at Terran Orbital allowed mission operators to quickly reconfigure the operational state of the spacecraft to stabilize the situation while recovery plans could be further evaluated.

Based on this exceptional effort and using the limited data available, the operations teams have determined that the spacecraft is in safe mode and appears to have successfully been placed in a stable state. The vehicle is in a rotating orientation that provides partial illumination of the solar panels and results in weak transmission signals from the spacecraft low gain antennas. Without the unique capabilities of the Deep Space Network, the mission team would have little or no information on the status of the spacecraft.

Modeling of the expected orientation and state of the vehicle into the future suggests it will remain stable. The vehicle is on the orbital trajectory intended and understanding this allows for continued tracking from ground stations well into the future. The vehicle in its current configuration is power positive, meaning that it is generating more power from the solar panels than the system is utilizing.

The mission operations team is currently focused on recovery plans. These efforts will begin by working to improve the thermal situation of several subsystems including the propulsion subsystem. While work is ongoing to diagnose the cause of the anomaly, the team is preparing the spacecraft to attempt a detumble operation to regain attitude control of the vehicle. This detumble operation was successfully demonstrated after separation from the launch vehicle in July. A successful detumble will result in the vehicle resuming control of its orientation, orienting the solar panels to the Sun to fully charge the batteries of the power used during the detumble. The spacecraft will then orient to the ground and await further instructions. These recovery operations will be further evaluated over the coming days. Recovery timing will be guided by the data and analysis available to maximize the probability of a successful spacecraft operation.

The combined mission team including the Deep Space Network, Terran Orbital, Stellar Exploration, and Advanced Space have been working in a disciplined and collaborative way to stabilize the CAPSTONE spacecraft and prepare for recovery. Many details remain unknown as to the cause of the anomaly and significant risks are continuing to be analyzed.

Everyone on the mission team is focused on recovering from this anomaly and continuing the important objectives of the CAPSTONE mission. As more details are available, they will be provided.
We appreciate the dedicated work of all mission partners involved in these activities and the supportive messages received during this stressful time.

CAPSTONE Teams Continue Work to Resolve Spacecraft Issue

Sarah Frazier Posted on September 12, 2022 4:42 pm

Following the Sept. 10 update on CAPSTONE, mission owner and operator Advanced Space has provided an update on the mission. Read the full update from Advanced Space.

During or shortly after a planned trajectory correction maneuver on Sept. 8, CAPSTONE suffered an issue that caused the spacecraft to tumble beyond the capacity of the onboard reaction wheels to control and counter. CAPSTONE was attempting to communicate with the ground for approximately 24 hours before any telemetry was recovered. After data was received, mission controllers found that the spacecraft was tumbling, the onboard computer systems were periodically resetting, and the spacecraft was using more power than it was generating from its solar panels.

Using NASA’s Deep Space Network, the combined mission team – including Advanced Space, Terran Orbital, Stellar Exploration, and NASA – re-established contact with CAPSTONE and reconfigured the spacecraft’s systems to stabilize the situation while recovery plans are evaluated. CAPSTONE remains in safe mode and now is power positive, meaning that it is generating more power from the solar panels than the system is using. Navigation data collected after the issue began suggests the Sept. 8 trajectory correction maneuver was completed or nearly complete when the issue occurred. This means the spacecraft remains on the intended trajectory and on course to its near rectilinear halo orbit at the Moon.

While work is ongoing to diagnose the cause of the issue, the team is preparing CAPSTONE to attempt a detumble operation to regain attitude control of the spacecraft.  This detumble operation was successfully demonstrated after separation from the launch upper stage in July. A successful detumble would give CAPSTONE control over its orientation, allowing it to orient the solar panels to the Sun to fully charge the batteries of the power used during the detumble. The spacecraft would then orient to the ground and await further instructions. These recovery operations will be further evaluated over the coming days. Recovery timing will be guided by the data and analysis available to maximize the probability of a successful spacecraft operation.

Updates will be provided as available.

CAPSTONE Mission: 15 September 2022 Update
Sep 15, 2022 | CAPSTONE Mission

On September 12th, we provided an update on the CAPSTONE mission. Below is an update.

CAPSTONE received some relatively good news on the recovery progress for the spacecraft. The communications situation has dramatically improved, the power state of the spacecraft appears to be sufficient for continuous (duty cycled) heating of the propulsion system which dropped below its operational temperature, Over the past few days, CAPSTONE’s power – though limited by the orientation of the spacecraft in its spin relative to the Sun – appears to be sufficient for heating of the propulsion system. When the spacecraft propulsion system temps are at +5C for 12+ hours the system will be further evaluated for use in the recovery operation. Information on the cause of the anomaly has been obtained and is being evaluated, and recovery plans that mitigate risk of further anomalous behavior are being developed. We do not have a timeline for a recovery attempt, but the team is working hard to make progress guided by what we are learning from the data with an explicit goal to minimize further risk to the mission.

The spacecraft continues on its planned path to the Near Rectilinear Halo Orbit around the Moon.

We are effusively grateful to the teams at the Deep Space Network, NASA, Terran Orbital, and Advanced Space who have supported this ongoing effort continuously over the past 5 days. Without the quick action and dedicated attention of all of these exceptional individuals, the CAPSTONE mission would likely have been lost due to this anomaly. As it stands today, the vehicle is stable, and the combined mission operations team is working towards attempting a recovery operation.

This remains a dynamic and changing situation. We are focused on working the technical situation with an emphasis on disciplined analysis supporting a well thought out recovery attempt. The success of the CAPSTONE mission remains our primary focus. As we are able to, we will continue to share information on progress.

Teams Work Ongoing Recovery Efforts for CAPSTONE 

Sarah Frazier Posted on September 15, 2022 4:15 pm

The CAPSTONE team continues work on recovery efforts. The primary ongoing focus now is to heat the spacecraft’s propulsion system, which dropped below its operational temperature limit following the initial issue that put the spacecraft into safe mode on Sept. 8. Over the past few days, CAPSTONE’s power – though limited by the orientation of the spacecraft in its spin relative to the Sun – appears to be sufficient for heating of the propulsion system. Once the spacecraft propulsion system temperature has been at 41° F (5° C) for at least 12 hours, the team will further evaluate the system for use in the recovery operation. Communications with the spacecraft have also improved, providing mission teams with more data from the spacecraft. Teams are evaluating the data to determine the cause of the issue and design recovery procedures to avoid similar problems during the attempted recovery operation.

Update from the CAPSTONE team today:

Has NASA / the CAPSTONE team identified what the "initial issue" was that put the spacecraft into safe mode? If so, what is it?
While work is still ongoing reviewing data on the exact root cause of the anomaly, we believe the most likely cause of the spacecraft losing attitude control and entering its current state originated from an unexpected thruster firing at the end of the planned Trajectory Correction Maneuver.

I've been following DSN Now on their website https://eyes.nasa.gov/dsn/dsn.html .

Earlier today I noticed there was a long uplink session. After that, there was a continuous, uninterrupted signal. I've been closely monitoring the downlink for the past hour and I didn't see any interruptions like before.

I can only hope the detumble operation has been successful and hopefully we'll soon get confirmation about that.

Hello, NASA? Advanced Space? I'm thinking about you... Please, share something... We haven't seen an update for more than a week.

https://eyes.nasa.gov/dsn/dsn.html

Advanced Space is likely still working furiously on the issue.
In the previous updates, finding the spacecraft tumbling, power negative, with the prop system thermally unsuitable (presumably too cold for firing a small RCS), and the wheels saturated is *NOT* a good place to be.

It seems from those updates that they were going to try and re-execute the de-tumble from tipoff (Launch), but were working through a bunch of items needed to be able to execute that.

Since they haven't posted any updates, it's safe to assume that they're still furiously working on troubleshooting and working to execute that recovery maneuver.

They're also likely being very careful as it would be easy to make things much worse.
I'd bet they're also pretty stressed from having a small team effectively going non-stop working a major mission anomaly.

That they recovered to a place where they were at least power positive, communicative, and thermally improving is a great recovery in its own right.

A stuck thruster at the end of a DV maneuver would be mission ending for many missions, so it's been a remarkable result even to get to where they last reported.

As an aside, I know some of this team personally from work on another mission, and these are the character of folks you'd want handling something really challenging. (I have no direct knowledge about CAPSTONE, all of the above is only my opinion.)

Every time I've caught a track on DSN Now, it was not stable (switching between carrier and data and/or the data rate changing).  That suggests to me that they are still spinning.
