Sierra Space confirms burst test of its fullscale inflatable module was successful

Sierra Space yesterday confirmed that the pressure test-to-failure of a fullscale inflatable space station module was successful in proving its safety and design.

The pressure shell for Sierra Space’s LIFE™ (Large Integrated Flexible Environment) habitat is made of expandable “softgoods,” or woven fabrics that perform like a rigid structure once inflated. During an Ultimate Burst Pressure (UBP) test, the teams inflate the test article until it fails, which helps determine how strong its softgoods materials would be under extreme stresses in the harsh environment of space. The full-scale unit in this test reached 77 psi before it burst, which well exceeds (+27%) NASA’s recommended level of 60.8 psi (maximum operating pressure of 15.2 psi multiplied by a safety factor of four).

A short video showing the moment the module bursts can be seen here.

The module is for the Orbital Reef commercial space station that Sierra Space is building in partnership with Blue Origin, which is supposed to be the lead company in the project. However, it is Sierra Space that appears to be building and testing hardware. What Blue Origin is doing remains unclear, as has been the case now for five-plus years.

Engineers shut lunar lander SLIM down in hope sunlight can recharge its batteries

Once they were able to download sufficient data, engineers have intentionally shut down Japan’s lunar lander SLIM in order to increase the chances it will recover should sunlight hit its solar panels and recharge its batteries.

The shutdown occurred three hours after landing on January 19, 2024, when the batteries still has a charge of about 12%.

Before turning the lander off remotely, mission control was able to receive technical and image data from its descent, and from the lunar surface. “We’re relieved and beginning to get excited after confirming a lot of data has been obtained,” JAXA said Monday in a statement, adding that “according to the telemetry data, SLIM’s solar cells are facing west”.

“If sunlight hits the Moon from the west in the future, we believe there’s a possibility of power generation, and we’re currently preparing for restoration,” it said.

The landing took place in the morning on the Moon, so there is a chance that in about a week, when the Sun shifts to the western sky, the panels will get sunlight and begin to recharge the battery.

Meanwhile, engineers confirmed that the two experimental mini-rovers were successfully deployed (see the media kit [pdf] for more details). At the moment we do not know if they have operated as planned, one rolling and the other hopping.

JAXA: SLIM soft landing successful but will likely die prematurely after landing

According to managers at Japan’s space agency JAXA, its SLIM lunar lander successfully completed its soft landing on the Moon.

It appears SLIM’s solar cells are not producing power. The spacecraft is presently on battery power, which will only last a few hours. Engineers are presently rushing to download images, taken during descent and after landing. There is also no word yet on whether the two test rovers were successfully released and achieved their test goals.

To precisely determine if the lander achieved its goal to hit a precise landing zone less than 300 feet across will require further analysis, much of which will depend on the images presently being downloaded. At the moment the engineers believe this goal was achieved, however, based on the telemetry already received.

Thus, it appears Japan has managed a soft-landing, something that in the past few years several countries (Israel, Russia, India, United States) and private companies (SpaceIL, Ispace, Astrobotic) have failed to do. Right now Japan appears to be the third nation to succeed in this new round of lunar exploration, joining China and India (which succeeded on its second attempt).

The next lunar landing attempt will be by the American private company, Intuitive Machines. Its Nova-C lander is scheduled for launch on a Falcon 9 rocket in mid-February.

SLIM lands on the Moon

Telemetry after SLIM's landing

According to telemetry data (as shown on the screen capture to the right), Japan’s SLIM lander has apparently landed on the Moon near Shioli Crater, proving its autonomous precision landing system worked as planned.

At the moment however Japan’s space agency JAXA has not yet confirmed that the landing was completely successful. After landing the announcers on the live stream repeatedly noted that though the telemetry indicated it had landed as planned, engineers had not yet confirmed that the lander was still operational. Note how the data to the right suggests the spacecraft is tilted slightly. This tilt appears to match the tilt of the surface, but it could also indicate a problem with communications.

A press conference announcing either a confirmation or a failure will begin shortly at the live stream above.

Chinese pseudo-company successfully completes rocket hop test

The Chinese pseudo-company Landspace successfully completed a rocket hop flight of its Zhuque-3 prototype hopper yesterday, testing vertical take-off and landing in preparation of recovering and reusing the first stage of its rockets.

The hop itself went to 350 meters and performed a small translation maneuver to the landing pad. The hope is called “ZQ-3 VTVL-1” which refers to “Vertical Takeoff – Vertical Landing”. It uses a single TQ-12 methane engine, which is also used on the current ZQ-2 rocket. The engine can throttle between 50-110% of the normal 80 tons of thrust, giving it a throttle range between 40 and 88 tons. The performed flight went on for roughly 60 seconds. The weight of the hopper is 50.3 tons.

Landpace confirmed the landing precision with 2.4 meters, with a landing speed of 0.75 meters per second, at a pitch angle of roughly 0.14 degrees, and a roll angle of 4.4 degrees. The hopper survived the hop and is already being inspected after the flight.

Video of the hop can be viewed at the link. The hopper is almost identical in concept to SpaceX’s Grasshopper test vehicle used by that company, flying with one engine of the same type used in its operational rocket.

If their test program continues as planned, Landspace hopes to begin flying reuseable stages in 2025, with that first stage capable of flying 20 times.

Of all the pseudo-companies in China, Landspace appears to be the most successful. It not only has an operational orbital rocket, Zhuque-2, that has carried satellites into orbit twice (here and here), it is very close to achieving rocket reuseability competitive with SpaceX.

Astrobotic’s Peregrine burns up in Earth’s atmosphere

At about 3:50 pm (Eastern) yesterday, the lunar lander Peregrine, built by the private company Astrobotic, hit the Earth’s atmosphere above the South Pacific and burned up, according to an update from the company.

The mission is over, having failed to reach the Moon due to a ruptured propellant tank caused by a leak in an interior helium tank.

The company was successful in regaining control over the mission after the leak, activating all payloads and getting data back from them, including images and even a short movie. It was also able to communicate with it from lunar distances. It failed however in testing its landing capabilities, its primary mission.

SpaceX successfully launches four astronauts to ISS on Axiom private mission

They’re coming for you next: SpaceX today successfully launched three European astronauts (plus the company capsule commander) to ISS on an Axiom private mission, its Falcon 9 rocket lifting off from Cape Canaveral at 4:49 pm (Eastern).

The capsule, Freedom, is flying humans into space for its third time. The first stage successfully completed its fourth flight, landing back at Cape Canaveral.

The mission itself is private, but the customer is the European Space Agency, which has paid the company Axiom to bring its astronauts to ISS for a fourteen day mission. Axiom in turn hired SpaceX to provide the rocket and capsule. This flight is confirmation that Europe has accepted the concept of capitalism in space, whereby it no longer depends on governments to accomplish what it wants, but instead is a customer buying those products from the private sector.

The astronauts are expected to dock with ISS early tomorrow morning.

SpaceX files for permits to build a shopping center and restaurant at Boca Chica

SpaceX has now filed for permits to build both a shopping center and restaurant at Boca Chica, with construction beginning in March and completed by the end of the year.

The location proposed is on the beach only a short distance to the west of SpaceX’s Starship/Superheavy facilities. It will be located looking north not at the Gulf of Mexico but at South Bay, one of the large inlets that surround the spit of land where those facilities are located. It is also located on roads that might not close during launches, which means it might be an excellent location to attract tourists during launches, about six miles from the launch site itself.

SLIM lowers orbit in preparation for January 19, 2024 lunar landing

The Japanese unmanned lunar lander SLIM, in orbit around the Moon since December 25, 2023, has now lowered its orbit in preparation for its lunar landing attempt, now scheduled for tomorrow, January 19, 2024, with operations beginning at 10:00 am (Eastern).

The image to the right indicates the targeted landing area near Shioli Crater. The mission’s prime engineering goal is to demonstrate precise robotic landing technology, able to land a spacecraft softly on another planet within a target zone less than 300 feet across. If successful it is expected to survive for about two weeks, studying the surface below it with a multi-spectral camera but also releasing two test probes, one a hopping rover and the second a rolling spherical rover. Both carry their own science instruments.

I have embedded the live stream for tomorrow’s landing below.

SpaceX requests 43 acres of nearby Boca Chica State Park, offering to expand another park by 477 acres

In order to “expand its operational footprint” at Boca Chica, SpaceX is asking to buy 43 acres of nearby Boca Chica State Park, and will offer as part of the purchase 477 acres adjacent to the Laguna Atascoca National Wildlife Refuge several miles to the north.

The link above includes maps showing the relative location of the properties. According to the meeting agenda for the Texas Parks and Wildlife department (TPWD), scheduled to take up this exchange next week, the commission already favors the deal.

“This acquisition will provide increased public recreational opportunities including hiking, camping, water recreation, and wildlife viewing, and allow for greater conservation of sensitive habitats for wintering and migratory birds,” the TPWD agenda stated. The agenda concludes by stating that the Commission finds that the proposed exchange is in the best interest of TPWD.

The public has been invited to comment on the deal at the meeting. Do not be surprised if we have a riot at that meeting of leftist activists protesting this deal.

Next manned mission to ISS to launch tomorrow

The next manned mission to ISS, a private mission by the company Axiom carrying three European astronauts and commanded by an Axiom astronaut, is presently scheduled to launch tomorrow, January 18, 2024, at 4:49 pm (Eastern).

This is a private mission by Axiom, launched on SpaceX’s Falcon 9 and flying the astronauts in its Freedom Dragon manned capsule. This will be Freedom’s third flight to ISS. The launch was originally scheduled for today, but SpaceX scrubbed the mission today in order to give it “additional time allows teams to complete pre-launch checkouts and data analysis on the vehicle.” It appears during normal prelaunch checkouts engineers found the joints between the upper stage and the capsule were not tightened the proper amount. The company decided to replace the joints, which caused this one day delay.

The crew will spend up to fourteen days at ISS.

I have embedded a live stream of the launch below.

Military awards satellite contracts worth $2.5 billion to three companies

The Pentagon’s Space Development Agency (SDA) today announced the award of contracts to Sierra Space, Lockheed Martin, and L3Harris for the construction of 54 reconnaissance satellites, with a total value of $2.5 billion.

The 54 satellites will form part of the SDA’s Proliferated Warfighter Space Architecture, a massive missile detection and tracking constellation in low Earth orbit that’s being built and launched in “tranches.” The trio of contracts announced today is for 18 satellites each in the Tranche 2 Tracking Layer: L3Harris’s award is worth $919 million; Lockheed Martin, $890 million; and Sierra Space, $740 million.

Last week SDA had awarded Rocket Lab its own 18-satellite contract for this constellation, worth $515 million.

The contract awards signal several major changes in the Pentagon’s space strategy. First, it is farming the work out to multiple companies, two of which (Rocket Lab and Sierra Space) are new. In the past the military relied on a very limited number of companies, all well established, with most contracts going to only one vender. New companies had great difficulties getting in the door.

Second, it is building a constellation of smallsats rather than single large satellites. Smallsats are cheaper to build and replace, and are much harder military targets to hit.

Third, though it appears the military is designing these satellites, it appears it is still shifting much of the work from it to the private sector. In other words, the Pentagon is becoming a customer instead of a builder. The result will be a healthy space industry capable of doing more for itself and the military.

Indian satellite startup opens new satellite factory

Capitalism in space: The Indian satellite startup Pixxel has opened a new factory in Bengaluru in southern India, where it expects to ramp up satellite production in the coming years.

Bengaluru-based space data company Pixxel inaugurated its first spacecraft manufacturing facility in Bengaluru on Monday. The new facility holds significance as it targets to launch six satellites this year and 18 more by 2025, further advancing its mission of building a “health monitor” for the planet.
Spread across 30,000 square feet, the facility, at its full capacity, is equipped to handle more than 20 satellites simultaneously that can be turned around within a timeframe of six months, making possible a total of 40 large satellites per year.

The company says that its “…total customer base is divided into three divisions as of now – 40 per cent agriculture, 30 per cent resource companies, and 30 per cent government. Pixxel expects 85 per cent of the revenue to be generated from its commercial side and the rest from the government’s side by 2025.”

For India’s government and its space agency ISRO, Pixxel’s existence signals the sea-change in its policies, similar to what has been happening in the U.S. with NASA. In the past ISRO would have built the satellites. Now it is buying them from the private sector in India. That shift bodes well for India’s space industry, and will likely make it a major player in space in the coming years.

SpaceX’s Starlink: More satellites in orbit but fewer close encounters

According to a recent filing with the FCC, SpaceX has found its Starlink constellation had to do fewer collision avoidance maneuvers in the past six months, despite having more satellites in orbit.

In that period, Starlink satellites had to perform 24,410 collision avoidance maneuvers, equivalent to six maneuvers per spacecraft. In the previous reporting period that accounted for the six months leading up to May 31, 2023, the constellation’s satellites had to move 25,299 times. The data suggests that even though the Starlink constellation has grown by about 1,000 spacecraft in the last six months, its satellites made fewer avoidance maneuvers in that period than in the prior half year.

At the moment it is not clear why the number dropped, especially as it had been doubling every six months previously as more satellites were launched. This might signal improved more precise orbital operations, or it could simply be a normal fluctuation. It will require additional reports to get a better sense.

These numbers however should rise as more larger satellites constellations (from Amazon and China) start launching as expected.

Elon Musk’s employee update released January 12th

I have embedded below an employee update of the status of all of SpaceX’s projects, given by Elon Musk and released publicly on January 12, 2023. The video has been edited only to remove the many enthusiastic applauses by Musk’s audience of co-workers in order to shorten it.

Though Musk provided a lot of general information about the company’s long term goals with Starlink, Starship, Mars, the Moon, and other topics, these are the most important take-aways relating to its ongoing efforts now:

  • Falcon 9: The company is now upgrading its first stage so that it will be able to fly reused forty times, not twenty. Musk also noted that they have now reused the rocket’s fairings more than 300 times.
  • They are now aiming for about 150 launches in 2024. (It appears now that the biggest obstacle to this goal will be weather, as seen by the weather delays that have stalled Falcon 9 launches this very week.)
  • The Dragon fleet has now spent more days at and flights to ISS than the NASA’s entire shuttle fleet.
  • Starlink: It is a supplement to present phone and internet service, not a replacement, serving remote areas. Its biggest obstacle now however to providing that service is government approvals. The company is blocked by regulators in many places where the service is operational.

On Starship/Superheavy, he revealed these facts:

  • They are planning to double its payload capacity to 200 tons to orbit, twice the Saturn-5.
  • Starship would have made orbit on the second orbital test if it had had a payload. To simulate the weight of payload it had carried extraoxidizer, and when it vented these as it approached orbit it caused problems that activated the self-destruct system.
  • The third orbital test flight will thus almost certainly reach orbit, and will then test engine burns, some refueling technology, payload deployment, and de-orbit procedures.

Musk emphasized that they must be able to fly these tests frequently to get Starship/Superheavy functioning, not just for SpaceX but for NASA’s Artemis program. As he said, “Time is the one true currency.” With each launch they refine the system to make it more reliable and operational. Without those launches they can’t.

He did not mention why launches might not happen frequently, probably because the last thing he needs to do is antagonize the regulators who are slowing him down. I (and other journalists) however are not under that restriction. The biggest obstacle to SpaceX’s success is the red-tape being wound around it by the Biden administration and its love of strict regulation, possibly instigated by its political hostility to Elon Musk as a person.

This government action to stymie freedom must end, and the sooner the better.

Peregrine still operational but expected to burn up in Earth’s atmosphere

Peregrine flight path as of January 13, 2024
Click for original image.

According to an update yesterday from Astrobotic’s engineering team, the damaged lunar lander is likely to enter the atmosphere burn up when its orbit brings it back to Earth in about a week.

In an update the day before, the company released a graph of the spacecraft’s position in relation to the Earth and Moon, shown to the right. From that update:

Peregrine remains operational at about 238,000 miles from Earth, which means that we have reached lunar distance! As we posted in Update #10, the Moon is not where the spacecraft is now (see graphic). Our original trajectory had us arriving at the Moon on day 15 post launch. Our propellant estimates currently have us running out of fuel before this 15-day mark

The plan had apparently been to circle the Earth twice in this elongated orbit, with the second orbit (after some mid-course corrections) bringing Peregrine close enough to the Moon (after it had moved further in its orbit) to be captured by its sphere of influence. With the loss of fuel due to the leak, the spacecraft doesn’t have the fuel to do any of the required engine burns, including one that would avoid the Earth’s atmosphere upon return.

Momentus delays next orbital tug mission due to lack of funds

The orbital tug startup Momentus has now delayed its next orbital tug mission, scheduled to launch in March on a SpaceX Falcon 9 rocket, due to shortage of cash in the bank.

In a filing with the U.S. Securities and Exchange Commission Jan. 12, Momentus announced it did not plan to fly its next tug, Vigoride-7, on SpaceX’s Transporter-10 rideshare launch in March. The company said it called off the flight because of its “inability to support continuing operations for the expected launch date as a result of the Company’s limited liquidity and cash balance.”

The company said in November that it has signed up seven customers who planned to deploy satellites on Vigoride-7 and two other customers who would operate hosted payloads on the vehicle, but did not identify then. Momentus also intended to fly a rendezvous and proximity operations demonstration on the vehicle as part of its long-term plans for reusable tugs.

Momentus also announced the layoff of 20% of its full-time workforce, on top of the 30% layoffs which occurred in the third quarter in 2023. It appears from the SEC filing that these layoffs are a result of not winning the military contract to build its Tranche-2 constellation, won by Rocket Lab earlier this week.

The company is presently seeking new investment capital.

Another look at the increasing regulatory burden impacting commerical space

Link here. The author does a nice job summarizing the problems now becoming evident as the administration state strives to expand its power and control. Though he gives space to both sides, allowing the defenders of that administrative state to explain why strong regulations are good, he doesn’t bow to those defenders, as do too many modern journalists.

That he quotes me extensively (and has has told me personally that he is a regular reader of Behind the Black), might have something to do with this. He isn’t parroting my positions, however, in this essay, but giving his own perspective.

Definitely worth reading.

Japan’s H2A rocket launches military surveillance satellite

Japan’s H2A rocket today successfully launched a new military surveillance satellite designed to observe North Korean’s missile launch sites.

The live stream of the launch is here, cued to T-10 seconds.

New reports had previously reported the last launch of the H2A occurred in September 2023, launching Japan’s SLIM lunar lander and XRISM X-ray telescope. This was obviously incorrect. Today’s launch appears to close out the H2A manifest, leaving Japan rocketless until it can get both its new H3 and grounded Epsilon rockets operational.

Boeing completes Starliner parachute drop test

Boeing on January 9, 2023 successfully completed a parachute drop test of its Starliner capsule, testing whether the redesigned connection between the chutes and the capsule was now meeting proper safety specifications.

The drop test, which used a Starliner parachute system attached to a dart-shaped sled the same weight as a Starliner, was performed to confirm the functioning of a redesigned and strengthened soft link joint that is part of the network of lines connecting the parachutes to the spacecraft. The test also validated a change to strengthen one textile joint in the parachute, increasing overall parachute robustness. As with other capsules, Starliner relies on parachutes to land safely when it returns to Earth.

Engineers are still analyzing the results, though the parachutes worked as planned. The first manned mission of Boeing’s commercial capsule is now scheduled for April 2024, only four years late as well as four years after SpaceX accomplished the same thing. It still remains staggering that the company did not find out about that soft link joint when it was designing the capsule, instead of only months before the first manned mission last year. It is not as if the use of parachutes to land capsules is cutting edge technology.

Blue Origin moves first stage of its New Glenn rocket from factory to launchpad hanger

In what might be the first step in assemblying Blue Origin’s New Glenn rocket for the first time (followed by a launch), the company yesterday transported the rocket’s first stage from its factory to its launchpad hanger.

Transported by a series of multiwheeled carriages and an arching structure, the 189-foot-tall first stage for what will be a 320-foot-tall rocket when fully assembled traveled horizontally on a 22-mile trip from the New Glenn factory in Merritt Island through Kennedy Space Center over to Cape Canaveral Space Force Station where Blue Origin has a hangar and launch pad at Launch Complex 36.

Jeff Bezos has said the company plans that first launch before the end of this year, though the company has been making this same promise now for the last three years, and is years behind schedule. What makes this promise different however is that this time we are seeing actual hardware moving towards the launchpad.

The article also gives a rough update on the company’s effort to manufacture the many BE-4 rocket engines needed for New Glenn (7) and ULA’s Vulcan rocket (2). The two engines for the next Vulcan launch in April are presently undergoing final testing at Blue Origin’s test facility in Texas, and the company says it is about to ramp up production. It thus appears that getting enough engines built is still the main obstacle to launch. We shall finally know later this year if Blue Origin has solved this problem.

Update on Astrobotic’s Peregrine lunar lander

The expected flight path of Peregrine
Click for original image.

The company Astrobotic has released several more updates on the status of its Peregrine lunar lander, which will no longer attempt a lunar landing because of a major fuel leak.

The map to the right shows its expected path in the coming days. While sent in a very elongated Earth orbit by ULA’s Vulcan rocket, the spacecraft was unable to do the additional engine burns that would have put it on the correct path to reach the Moon. Instead, it will fall back towards Earth, though its fate beyond that is unclear at this time.

Meanwhile, engineers have succeeded in getting data from all payloads designed to communicate back to Earth.

We have successfully received data from all 9 payloads designed to communicate with the lander. All 10 payloads requiring power have received it, while the remaining 10 payloads aboard the spacecraft are passive. These payloads have now been able to prove operational capability in space and payload teams are analyzing the impact of this development now.

Engineers have also been able to get the spacecraft to send back a number of images. These successes help the company prove out some of the spacecraft’s systems, though it is unable to test the mission’s prime goal, landing on the Moon.

China successfully launched twice today

China completed two different launches from two different launch locations today, with one being the first launch of a new rocket.

First, China’s solid-fueled Kuaizhou-1A lifted off from the Jiuquan spaceport in northwest China, placing what the state-run press described as a “satellite is mainly used for experiments such as space environment detection.” No other information was released. Nor was any information released about where the rocket’s lower stages crashed inside China.

Next, a Chinese pseudo-company, Orienspace, completed the first launch of its new Gravity-1 rocket, lifting off from a barge off the coast of Haiyang in the Yellow Sea carrying three satellites. The state-run press once again failed to mention this company’s name in its report, describing it instead as a “launch by China”, illustrating again the lack of independence these pseudo-companies have. They might design and build on their own, but they are controlled entirely by the communist government, and at any time can be taken over by it.

Though the rocket itself appears very similar in many ways to India’s largest version of its liquid-fueled GSLV rocket, very squat with four strap-on boosters, Gravity-1 is solid-fueled (thus derived from the missile technology controlled by China’s military). It is also the most powerful solid-fueled rocket now in operation, twice as powerful as Europe’s Vega-C.

NASA awards more money to two private space station proposals

Because Northrop Grumman has dropped its plans to build its own private space station, joining instead the Starlab station consortium led by Voyager Space, NASA has been able to shift the funding planned for Northrop Grumman’s station to two other two private space station projects.

Voyager Space’s Starlab station development will receive an additional $57.5 million from NASA, which brings NASA’s total funding for Starlab so far to $217.5 million, the space agency said.

…The Orbital Reef space station of Blue Origin and Sierra Space is receiving an additional $42 million, bringing that project’s total NASA funding so far to $172 million.

NASA says the extra money will help both consortiums meet their schedules.

A third private station, Axiom, also under development in partnership with NASA, plans to dock its initial modules to ISS, and then undock when completed to fly free.

A fourth American private space station is also being built, but independent of NASA entirely. The company, VAST, has teamed up with SpaceX to launch its first modules on Starship/Superheavy, followed by at least two manned missions.
