Rocket startup ABL abandons its effort to build a rocket

The rocket startup ABL, which had one failed launch attempt and a second failure during a static fire test, announced yesterday in a long tweet on X that it is abandoning its effort to build a rocket and will instead use its assets to provide products to the military.

[W]e have made the decision to focus our efforts on national defense, and specifically on missile defense technologies. We’ll have more to share soon on our roadmap and traction in this area. For now, suffice to say we see considerable opportunity to leverage RS1, GS0, the E2 engine, and the rest of the technology we’ve developed to date to enable a new type of research effort around missile defense technologies.

In other words, they are repurposing their RS1 rocket for missile technology.

The company’s announcement claims this decision is partly because the competition from established companies diminished its opportunity to gain market share, but I think its real problem was twofold. First, failure breeds failure. ABL’s rocket failures, combined with its very slow response after each failure, probably caused a shrinkage in investment capital. For example, one of its biggest investors had been Lockheed Martin, which had signed ABL up for a big launch contract. ABL’s failure to get its rocket off the ground however had Lockheed switch rocket companies, signing a new launch deal with Firefly in 2024. ABL had thus lost its biggest customer.

Second, as a new company with a rocket under development, it probably faced heavy regulatory burdens getting new launch licenses. The FAA under its “steamlined” Part 450 regulations probably required new license applications every time the company realized it needed to redesign something, and that red tape made it difficult to move forward.

In any new industry one must expect a shake-out to occur whereby many of the startups fail or get absorbed by others. This is natural. It is unfortunate however that government regulation has become an unnecessary and unnatural factor in this shake-out.

New thermal protection system developed by Sierra Space

Sierra Space yesterday announced that it has developed in partnership with Department of Energy’s Oak Ridge National Laboratory in Tennessee a new thermal protection system (TPS] that it expects will give its Dream Chaser mini-shuttles a heat shield that can be reused frequently and fast.

The TPS tiles are made of a proprietary composite material that’s as strong as carbon fiber but with the added high-temperature stability of ceramic materials. The composite tiles have low-density thermal protection properties that are vital for insulative protection and stable flight dynamics. Atmospheric re-entry exposes spacecraft to speeds of more than Mach 17 (About 13,000 mph or 21,000 kph) with temperatures reaching higher than 3,100 degrees Fahrenheit (1,704 degrees Celsius).

These new tiles are based on the shuttle tiles, but apparently use carbon fibers to strengthen them so they are more robust and require less replacement. The shuttle tiles were much too fragile, requiring significant replacement after each launch. That fragility also caused the destruction of Columbia on its return to Earth in 2003, because the tiles were damaged badly when hit by foam coming off the shuttle during launch.

SpaceX scraps its land swap offer to Texas

SpaceX has decided to scrap its land swap offer to Texas, whereby the company would have given the state 477 acres of wildlife land it owns elsewhere in exchange for ownership of 43 acres of state park land adjacent to its Boca Chica facility.

In a Sept. 26 letter seen by Bloomberg News, SpaceX Vice President Sheila McCorkle told the Texas Parks and Wildlife Department that the company “is no longer interested in pursuing the specific arrangement.”

In exchange for SpaceX getting the 43 acres, the company would have given the state some 477 acres of its land near Laguna Atascosa National Wildlife Refuge, around 10 miles away. The land could have given Texans access for hiking, camping and other recreational purposes, the Texas Parks and Wildlife Commission said. In March, the commission approved the deal.

Environmental activists worry their fight’s not over with SpaceX and Musk, who has achieved newfound political power through his close ties to President-elect Donald Trump. “We’re concerned that he has something bigger and more disruptive to the beach and to the wildlife in mind,” Bekah Hinojosa, a representative from the South Texas Environmental Justice Network, an advocacy group, said in an interview. [emphasis mine]

The blind opposition of these leftist activists to Musk and anything he does has merely caused them to cut off their nose to spite their face. SpaceX’s proposal would have given the public a much larger wildlife area that was also far enough away from Boca Chica to allow its use all the time. Now the state is stuck with 43 acres of state park land that is going to be useless whenever Starship/Superheavy launches.

The lawsuits against this swap claimed it violated the Texas constitution. My guess is that SpaceX decided it wasn’t worth fighting this battle. Or maybe it is now playing hardball in negotiations. These activists do not have the support of the local community, which wants SpaceX’s operations to be successful. By scrapping the plan now SpaceX might be acting to force the Texas legislature to change the law to make the land swap legally acceptable.

SpaceX and Amazon take their lawsuits against the NLRB to a higher court

NLRB logo

Both SpaceX and Amazon have now brought their lawsuits questioning the very constitutionality of the National Labor Relations Boards (NLRB) enforcement structure to the Fifth Circuit of the U.S. Court of Appeals.

The two companies—founded by the world’s two richest men—will each square off against the [NLRB] that protects workers’ unionizing rights during separate oral argument sessions at the US Court of Appeals for the Fifth Circuit on Nov. 18.

The Fifth Circuit has played a central role in the intensifying constitutional attacks on the NLRB. District courts in Texas, one of three states covered by the Fifth Circuit, have granted the only preliminary injunctions to block agency proceedings based on constitutional arguments.

A lower court judge has already ruled in favor of SpaceX’s lawsuit [pdf], stating that “Under binding precedent, this Court is satisfied that SpaceX has demonstrated a substantial likelihood of success on its claims that Congress has impermissibly protected both the NLRB Members and the NLRB ALJs [administrative law judges] from the President’s Article II power of removal.”

The arguments by both Amazon and SpaceX were greatly strengthened by the Supreme Court’s decision in June 2024, ruling that the SEC’s use of administrative law judges is unconstitutional. Much of that ruling’s logic applies directly to this NLRB case.

Blue Origin links the first and second stages of New Glenn for the first time

New Glenn finally stacked
Click for original image.

After more than a decade of development and five years overdue, Blue Origin earlier this week finally intergrated the two stages of its New Glenn rocket in preparation for its first launch.

The picture to the right shows the rocket stacked horizontally in Blue Origin’s rocket facility in Florida.

The company still has to roll the rocket out to the launchpad, raise it to a vertical position, and conduct at least one dress rehearsal countdown ending in a short static fire test of the first stage’s seven BE-4 engines. At the moment the company is targeting a November launch.

New Glenn is expected to make its maiden flight sometime in November, taking off from Launch Complex 36 at Cape Canaveral Space Force Station, which is next door to KSC. The flight will carry one of the company’s new Blue Ring spacecraft on a National Security Space Launch certification flight known as DarkSky-1 and sponsored by the Defense Innovation Unit.

The original payload for this launch, two small NASA Mars orbiters, had been pulled because Blue Origin couldn’t get the rocket ready in time for its October launch window. Blue Ring is Blue Origin’s own orbital tug and satellite platform, and this flight is probably intended to get it certified for national security payloads.

The fast development of Blue Ring might give us a hint as to the changes to Blue Origin’s culture since Bezos replaced its previous CEO, Bob Smith, with Dave Limp in September 2023. Blue Ring was announced only one month later, and in just over a year it is now ready for its first launch. Such speedy development has not been the way at Blue Origin for years, if ever. If Limp has been able to instill that urgency across the entire company, then we shall some very exciting achievements from Blue Origin indeed in the next few years.

AST Spacemobile signs multi-launch agreement with Blue Origin

The direct-to-cell satellite company AST Spacemobile announced yesterday that it has signed a multi-launch agreement with Blue Origin to use its New Glenn orbital rocket to place approximately sixty of its second generation BlueBird satellites into orbit in the 2025-2026 time frame.

The next-generation Block 2 BlueBirds are designed to deliver up to 10 times the bandwidth capacity of the BlueBird satellites in orbit today, accelerating the goal to achieve 24/7 continuous cellular broadband service coverage. The service will target approximately 100% U.S. nationwide coverage from space with over 5,600 coverage cells, with beams designed to support a capacity of up to 40 MHz, enabling peak data transmission speeds up to 120 Mbps, supporting voice, full data and video applications. The Block 2 BlueBirds, featuring up to 2,400 square foot communications arrays, will be the largest ever commercially deployed in low Earth orbit once launched, surpassing the current record held by AST SpaceMobile’s BlueBird 1-5 and BlueWalker 3, each ~700 square feet in size.

The Block 2 BlueBirds are designed to be compatible with all major launch vehicles. Blue Origin’s launch vehicle, the New Glenn, offers a seven-meter fairing enabling twice the payload volume of five-meter class commercial launch systems, and is well-suited to launching up to 8 of the largest-ever Block 2 BlueBirds.

According to this, the contract is for approximately 7 to 8 New Glenn launches. It also notes the large capacity of New Glenn apparently gives it an advantage over the rockets available from both SpaceX and ULA. If (the operative word) Blue Origin can finally get this rocket off the ground soon, it will then finally provide some real competition to SpaceX.

We shall see. New Glenn is five years behind schedule, and all signs suggest the company continues to move at a relatively slow pace compared to its competitors. It has said it wants to do the first New Glenn launch before the end of the year, but that remains uncertain.

FAA forming new committee to revise its launch licensing regulations

The timing is interesting: The FAA yesterday announced that it wishes to form a committee of “members of the commercial space industry and academia” to revise its Part 450 launch license regulations that were introduced in 2021 supposedly to streamline the process but have instead served to squelch innovation and new rocket startups significantly.

“The FAA is seeking to update the licensing rule to foster more clarity, flexibility, efficiency, and innovation,” said FAA Associate Administrator for Commercial Space Transportation Kelvin B. Coleman. “Making timely licensing determinations without compromising public safety is a top priority.”

The Part 450 rule was developed to streamline the regulations, reduce the number of times an operator would need to come to the FAA for a license approval and decrease the need for the FAA to process waivers, among other goals.

The committee will consist of members of the commercial space industry and academia and will focus on nine topics, including flight safety analyses, system safety, and means of compliance. It is expected to submit a report with recommended changes to Part 450 rule by late summer 2025. The FAA would then use the recommendations to plan future rulemaking actions. [emphasis mine]

The highlighted words are a lie. While established rockets might have benefited — allowing more launches, Part 450 has practically squelched new development because it forces companies to undergo lengthy reviews every time they attempt to introduce any new technology or redesign to their rockets. SpaceX’s experience with Starship/Superheavy is only the tip of the iceberg, because the company is big enough that it has been able to survive these reviews and push on. Almost all of the new rocket startups that were on the verge of launching in 2020, before Part 450 went into effect, have either delayed launches for years or gone bankrupt.

The FAA hopes to conduct the first meeting of this new committee by the first week in December. It apparently realizes that the Trump administration is going to demand a major change in Part 450 (possibly a complete repeal), and the agency wishes to get ahead of this to maybe fix things.

NASA begins search for new headquarters building

NASA yesterday announced that — because its present lease expires in August 2028 — it is seeking proposals for a new headquarters building in the Washington, DC region.

NASA is asking for responses from members of the development community, local and state jurisdictions, academia, other federal agencies, commercial aerospace partners, and other interested parties to help inform its decision.

Needs for a new headquarters includes approximately 375,000 to 525,000 square feet of office space to house NASA’s workforce. The desired location is within walking distance to a Washington Metropolitan Area Transit Authority station. In addition, the new location also needs parking options, as well as convenient access to food establishments.

It seems to me that this is an ideal opportunity to reduce the size of NASA’s management structure. Since the agency has largely accepted the idea of capitalism in space, whereby it builds almost nothing but instead gets what it needs in the private sector, much of its large overhead and staffing that presently exists and was created when NASA attempted to do it all is now unneeded and is actually redundant. Rather than replace and expand NASA’s present headquarters, which appears to be the agency’s goal, the Trump administration should shrink its size, significantly.

Not only would the taxpayer save money, NASA would be further forced to use the private sector for its needs, thus fueling the growth of that aerospace industry. And for those laid off, they will likely have no trouble getting jobs in this new energized private sector.

All in all, such a reduction would be a win-win, for everyone.

China launches Tianzhou cargo freighter to its Tiangong-3 space station

China today successfully launched a new Tianzhou cargo freighter to its Tiangong-3 space station, its Long March 7 rocket lifting off from its coastal Wenchang spaceport.

The leaders in the 2024 launch race:

114 SpaceX
53 China
13 Russia
12 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 132 to 79, while SpaceX by itself leads the entire world, including American companies, 114 to 97.

  • ESA touts its plans to build a low cost, super heavy-lift reusable rocket
    The space agency asked two European rocket companies to propose concepts, from which ESA will then decide what to do. Or to put it another way, ESA is still designing and owning the rocket instead of getting the product from the private sector. This rocket will therefore be the same kind of failure that Ariane-6 has been, expensive, inefficient, and uncompetitive.

Boxwork in the dry Martian tropics

Boxwork on Mars
Click for original image.

Cool image time! The picture to the right, cropped and enhanced to post here, was taken on July 17, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as boxwork, a pattern of intersecting straight ridges criss-crossing each other in a generally random manner.

The ridges themselves are very small, only a few feet high. To make them more visible I have purposely cropped this section without reducing its resolution. I have also increased the contrast.

What caused them? According to this paper [pdf] about similar boxwork found on Mount Sharp in Gale Crater, the boxwork “formed when cements filled existing pore spaces and fractures in fractured rock, and these cements were left as topographic ridges after erosion.”

In other words, the surface hardened, then fractured. Later more resistent material, likely lava, filled the cracks. When erosion later stripped the top surface away, the lava was more resistent and so became the ridges we now see.

NASA reveals that it and Russia disagree about the danger posed by the airleak on ISS

Figure 3 from IG report
Figure 3 from September Inspector General report, annotated by me to show Zvezda location.

In a public session yesterday by a NASA commission focused on accessing the safety condition of ISS, officials revealed that the commission and Russia disagree about the root causes behind the airleak and cracks in the docking section of the Zvezda module on the Russian half of ISS, as well as the risk of a catastrophic failure. According to the commission’s head, former astronaut Bob Cabana.

The Russian position is that the most probable cause of the PrK cracks is high cyclic fatigue caused by micro vibrations. NASA believes the PrK cracks are likely multi-causal including pressure and mechanical stress, residual stress, material properties and environmental exposures.

The Russians believe that continued operations are safe, but they can’t prove that to our satisfaction. The U.S. believes that it’s not safe, but we can’t prove that to Russian satisfaction that that’s the case. So while the Russian team continues to search for and seal the leaks, it does not believe catastrophic disintegration of the PrK is realistic and NASA has expressed concerns about structural integrity of the PrK and the possibility of a catastrophic failure.

Because of this disagreement American astronauts now close the hatch between the Russian and American halves of ISS whenever a docking to Zvezda is taking place, and apparently keep that hatch closed until unloading of the docked spacecraft is complete. The Russians in turn only open the hatch to the docking section of Zvezda when they need to load or unload material into the freighter docked there, and coordinate with American astronauts whenever they do so.

Engineers from the two nations continue to discuss the issue, and hope to result their disagreement and come up with a joint plan.

Ultimately, this issue indicates the certain end of ISS in the near future, and adds ugency to the need to get some of those commercial space stations operating in orbit.

Pakistan to fly a small rover on China’s Chang’e-8 lunar lander

In an agreement signed yesterday, the Space and Upper Atmo­sphere Research Comm­ission (Suparco) in Pakistan announced it will collaborate with China to build a small rover that will to fly on China’s Chang’e-8 lunar lander.

The lander is present scheduled to land near the Moon’s south pole in 2030, will be China’s second lander to the south pole region, and will also act to officially establish China’s International Lunar Research Station (ILRS) on the lunar surface. It will also include a “hopper” to explore the nearby surface.

Pakistan had already signed on to China’s space alliance to build the ILRS. China’s present list of partners is as follows: Azerbaijan, Belarus, Egypt, Kazakhstan, Nicaragua, Pakistan, Russia, Serbia, South Africa, Thailand, Turkey, and Venezuela. That partnership also includes about eleven academic or governmental bureaucracies.

Denmark joins the Artemis Accords

In a signing ceremony yesterday in Copenhagen, Denmark became the 48th nation to sign the Artemis Accords.

The full list of nations now part of this American space alliance: Angola, Argentina, Armenia, Australia, Bahrain, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, France, Germany, Greece, Iceland, India, Israel, Italy, Japan, Lithuania, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Peru, Poland, Romania, Rwanda, Saudi Arabia, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

With this alliance established, the incoming Trump administration will have great political international leverage, increasing the chances it can finally use the accords to achieve its initial goal, to overcome the legal restrictions on private property imposed by the Outer Space Treaty.

China and SpaceX complete morning launches

Both China and SpaceX today successfully completed morning launches.

First China launched an environmental satellite to study “ocean salinity,” its Long March 4B rocket lifting off from its Taiyuan spaceport in northeast China.

No word on where the rocket’s lower stages crashed inside China. All use very toxic hypergolic fuels, which can literally dissolve your skin.

Next SpaceX completed another launch of 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its eighteenth flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

114 SpaceX
52 China
13 Russia
12 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 132 to 77, while SpaceX by itself leads the entire world, including American companies, 114 to 95.

SpaceX launches 20 Starlink satellites

SpaceX tonight successfully launched 20 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg in California.

The satellites included 13 of the Starlink direct-to-cell satellites. The first stage successfully completed its eighth flight, landing on a drone ship in the Pacific.

The leaders in the 2024 launch race:

113 SpaceX
51 China
13 Russia
12 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 131 to 76, while SpaceX by itself leads the entire world, including American companies, 113 to 94.

Major court decision could invalidate many federal environmental regulations

In what could be a major legal ruling [pdf], a two-judge decision this week in the DC Circuit Court ruled that the White House Council on Environmental Quality (CEQ), which has for years imposed environmental rules on other federal agencies based on the National Environmental Policy Act (NEPA), does not have the statutory authority to do so, thus invalidating every regulation so imposed.

All three members of the three-judge panel agreed that the Agencies acted arbitrarily and capriciously in [in this particular case]. However, before reaching that conclusion, the majority analyzed whether the CEQ regulations the Agencies followed in adopting the plan were valid, an argument not raised by any of the parties. The majority held, sua sponte, that because there is no statute stating or suggesting that US Congress has empowered the CEQ to issue rules binding on other agencies, the CEQ has no lawful authority to promulgate such regulations.

…Although this decision does not explicitly vacate any action taken by the CEQ, it does establish a precedent that CEQ rules lack statutory authorization, and therefore that other agency actions taken under the CEQ framework are at risk of being vacated. If this decision is not overturned by the full appellate court sitting en banc or by the US Supreme Court, it has the potential to completely change the landscape of NEPA review.

The case is complicated, partly because the Byzantine nature of the federal bureaucracy and the many agencies involved. (It is almost as if these agencies created that complexity to confuse and protect themselves.)

The heart of the decision is that CEQ was apparently first created as an “advisory” body to help other federal agencies follow the intent of NEPA in their own rule-making, but instead soon became a “regulatory” body whose rulings other agencies were required to follow. As that authority was never given it by Congress, CEQ exceeded its authority by making its rulings mandatory.

This court decision will likely leave many agencies on their own in establishing environmental regulations, based on NEPA. However, even that regulatory ability faces limitations, based on the Supreme Court’s recent Chevron decision, which said that government agencies do not have right to promulgate new regulations that are not specifically described in congressional law.

In other words, Chevron says that the bureaucracy cannot make things up, based on its own vague opinions.

The trend of all these court rulings appears aimed at limiting the power of the federal bureaucracy. It will however take some time to determine how much that power is limited, as lawsuits begin to percolate through the courts. If there are lot of lawsuits (which does appear to be happening) we should therefore expect that power to be limited significanly.

Another cool hiking location on Mars

Overview map

Another cool hiking location on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 10, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

My reason to posting this I admit is selfish and tourist-oriented. This narrow ridge, about a mile long and about 300 to 600 feet high, appeals directly to my hiking passions. A trail along its length would provide any hiker some really spectactular views.

The scientists took the picture because of the geology. The white dot on the overview map above marks the location, a short channel dubbed Daga Vallis that connects two major canyons in the eastern part of Valles Marineris, the largest known canyon system in the solar system. This ridge and several nearby parallel ridges were apparently made of something, possibly lava, that was resistent to the theorized ancient catastrophic floods that scientists presently believe carved out these channels and canyons.

In the inset the dotted line indicates one possible hiking trail route that travels the full length of the ridge but then heads south to continue along the rim of a 1,200-foot-high cliff face. For future Martian colonists, I offer this site as a great place to set up a bed-and-breakfast, surrounded by many potential hikes of incredible stark beauty.

Rocket Lab announces first launch contract for its new Neutron rocket

Though the press release was lacking in many details, Rocket Lab yesterday announced the signing of its first launch contract for its new Neutron rocket, scheduled to make its first orbital test launch in 2025.

Under the contract, Rocket Lab will launch two dedicated missions on Neutron starting from mid-2026. The missions will launch from Rocket Lab Launch Complex 3 on Wallops Island, Virginia. The launch service agreement for these missions signifies the beginning of a productive collaboration that could see Neutron deploy the entire constellation.

The press release did not name the satellite constellation, or the company building it. Rocket Lab’s founder and CEO, Peter Beck, was quoted as follows: “Constellation companies and government satellite operators are desperate for a break in the launch monopoly.” [emphasis mine] That launch monopoly is clearly SpaceX, and Beck was positioning Rocket Lab with Neutron as the company to provide an alternative.

The announcement as well as the company’s third quarter report caused a 45% surge in its stock price.

The dim future of SLS indicated at space business symposium

At a symposium in DC yesterday, a panel of past managers — all of whom had been involved in previous government transitions at NASA — attempted to predict what the consequences will be for NASA with the new Trump administration.

Most of the opinions were pure guesses, some better than others. The real moment of truth came when the entire panel was asked to predict the future of SLS and Orion. The question was put forth by one of the panelists, Lori Garver, who had been NASA’s deputy administrator during the Obama administration, and seemed to have the best understanding of how much the arrival of Trump will likely shake things up significantly.

At one point in the discussion, she asked the panel if they thought the Space Launch System and Orion programs would continue in the next administration. None of the panelists raised their hands. [emphasis mine]

Several of these panelists were big supporters of SLS. Their lack of confidence in its future tells us that SLS and Orion no longer have strong political backing in Washington. Both stand on thin ice.

I predict both will be shut down within the next year, before the next Artemis flight, the first to be manned, to be replaced with a entirely different manned space exploratory program to the Moon and Mars. The decision will be a smart one, but tragically late in coming. SLS should have been dumped years ago. If it had, the U.S. effort to return to the Moon would have been better off, moving forward with a better plan years earlier. Instead, this late decision will once again delay any manned lunar missions for years more.

The change however will be good in the long run, because I expect the new program will be better designed, more efficient, cost less, and be able to do what SLS promised but could never deliver. And it will be based on what private enterprise can accomplish, not a government designed behemoth designed mostly as pork.

Firefly raises $175 million in new private investment capital

The rocket startup Firefly has now raised another $175 million of private investment capital, during a new round of funding, on top of another $300 million raised previously.

Firefly Aerospace has raised $175 million in a round led by a new investor to support production of launch vehicles and spacecraft with an increased focus on responsive space capabilities.

The company announced Nov. 12 it raised what it described as an oversubscribed Series D round led by RPM Ventures. Several other existing and new ventures also participated in the round, which values Firefly at more than $2 billion.

That valuation is an increase from the $1.5 billion the company reported in November 2023 when it closed the final tranche of a Series C round. The company did not disclose the size of that earlier round but said then it had raised about $300 million since February 2023.

It appears RPM likes how the company has focused on providing the military launch services, which can also be profitable for private satellite customers. This money will be used to help increase the production of Firefly’s Alpha rocket.

JPL to layoff 5% of its workforce, the third major layoff this year

JPL in California announced today a layoff of 325 workers, about 5% of its workforce, the third major layoff imposed this year.

The JPL press release indicates the layoffs are because of NASA budget cutbacks, but does not provide any specificity. The cause centers mostly around NASA’s decision to pause its Mars Sample Return project, which JPL was leading. From this report:

This is the third round of layoffs at JPL this year, a reduction spurred primarily by major budgetary cuts to the Mars Sample Return mission, which is managed by JPL. NASA directed $310 million this year to the effort to bring Mars rocks back to Earth, a steep drop from the $822.3 million it spent on the program the previous year.

In January, 100 on-site contractors at JPL were let go after NASA instructed the lab to reduce spending in anticipation of a much tighter budget. In February, the lab laid off 530 employees — approximately 8% of its workforce — and another 40 contractors.

It increasingly appears that JPL’s place in the redesigned mission could be significantly reduced.

The press release also makes it sound like these cutbacks are the end of the world. As JPL has mostly functioned for decades as a private institution attached to NASA almost like a government agency, no one there ever expects to get laid off. In the real world however layoffs such as this happen all the time, especially when a company fails to deliver. JPL in recent years has had budget and management problems, epitomized by the problems now seen with that sample return mission, so it should not be surprised by these cutbacks from NASA.

Cargo Dragon docked to ISS boosts station

For the first time a cargo Dragon capsule used its Draco attitude thrusters to test their ability to adjust or raise ISS’s orbit.

NASA and SpaceX monitored operations as the company’s Dragon spacecraft performed its first demonstration of reboost capabilities for the International Space Station at 12:50 p.m. EST on Friday. The spacecraft’s Draco thrusters adjusted the station’s orbit through a reboost of altitude by 7/100 of a mile at apogee and 7/10 of a mile at perigee, lasting approximately 12 minutes and 30 seconds.

This posting is late because of my Grand Canyon trip, but I’m posting this now to make sure it is on the webpage. The goal of the test was to prove another American method for adjusting ISS’s orbit, in order to replace the Russian Progress capsules which now do the job. This test proved Dragon’s thrusters can be used for small orbital adjustments, but whether it can do major orbital corrections remains unclear. A previous test using Cygnus had already showed it could do the job.

Polaris completes first inflight ignition of its aerospike engine

In what appears to be a first, Polaris Spaceplane on October 29, 2024 successfully completed the first ever inflight ignition of an aerospike engine, using its Mira-2 unmanned engineering prototype.

Later in the day on 29 October, MIRA II took off from Peenemünde Airport on the coast of the Baltic Sea with a takeoff mass of 229 kilograms, which represented a reduced propellant load. The vehicle flew to the ignition point over the Baltic Sea, approximately 3 kilometres away from the ground station, and once there, completed a short three-second burn of its AS-1 aerospike engine. During the short burn, MIRA II experienced an acceleration of 4 m/s².

According to the company, the engine operated at a reduced chamber pressure during the three-second burn, resulting in a fuel-rich combustion.

There have been several attempts in the past to develop the aerospike engine, none of which ever completed any test flights, as far as I am aware. The concept is that the thrust is released in a string of openings, with only one wall forming the nozzle shape and the atmosphere used to complete the nozzle on the other side. As the atmospheric density changes the nozzle shape thus changes its shape, producing the most efficient thrust throughout the engine’s entire flight.

More test flights will be required before the company will be able to begin work on its full scale Aurora spaceplane.
