SpaceX successfully completes two launches today

11:40 am

SpaceX successfully completed two launches today, one from each coast.

First in the early morning the company sent 20 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its 20th flight, landing on a drone ship in the Pacific. Of the 20 satellites, 13 were configured for direct-to-cell service.

Next, SpaceX launched GSAT-20, a geosynchronous communications satellite for India’s space agency ISRO, which hired SpaceX because the satellite was too heavy for its own rockets. The Falcon 9 rocket lifted off from Cape Canaveral, with the first stage completing its 19th flight, successfully landing on a drone ship in the Atlantic. Of the two fairings, one completed its fifth flight while the second completed its first flight.

If we include the afternoon launch yesterday by SpaceX from Kennedy, the company did three launches from three locations in less than 24 hours. And it hopes to launch again tomorrow, this time flying Starship/Superheavy on its sixth test orbital flight, launching from the company’s launchpad in Boca Chica. I have embedded the live steam here.

The leaders in the 2024 launch race:

117 SpaceX
53 China
13 Russia
12 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 135 to 79, while SpaceX by itself leads the entire world, including American companies, 117 to 97.

With these two launches today, the all-time global record for successful orbital launches in a year, set only last year at 213, has been broken, and there are still about five weeks left in 2024.

A new geologic map of one of the Moon’s largest impact basins

10:00 am

Orientale Basin on the Moon
Click for original image.

Using data from Lunar Reconnaissance Orbiter (LRO), scientists have now produced a high resolution geological map of Orientale Basin, one of the largest impact basins on the Moon — at about 600 miles across — and located just on the edge of the Moon’s visible near side.

That map is to the right, reduced and sharpened to post here. You can read the paper here [pdf]. From the press release:

Planetary Science Institute Research Scientist Kirby Runyon is a lead author on a paper published in the Planetary Science Journal containing a new high-resolution geologic map of Orientale basin that attempts to identify original basin impact melt. The hope is that future researchers use this map to target sample return missions and pin down impact dates for this and other impact basins.

“We chose to map Oriental basin because it’s simultaneously old and young,” Runyon said. “We think it’s about 3.8 billion years old, which is young enough to still have its impact melt freshly exposed at the surface, yet old enough to have accumulated large impact craters on top of it as well, complicating the picture. We chose to map Orientale to test melt-identification strategies for older, more degraded impact basins whose ages we’d like to know.”

The map’s prime purpose is to pin down locations where material from the actual impact exist and can be returned to Earth for precise dating, thus helping to create a more accurate timeline of the Moon’s formation as well as the entire solar system’s accretion rate.

A spiral galaxy as seen from the side

A spiral galaxy seen from the side
Click for original image.

Cool image time! The picture to the right, reduced to post here, was taken by the Hubble Space Telescope of what is believed to be a spiral galaxy seen edge-on. The galaxy itself is estimated to be 150 million light years away, and this view highlights two major features, the dust lanes that run along the galaxy’s length and its distinct central nucleus, bulging out from the galaxy’s flat plain.

The way this image was produced however is intriguing on its own:

Like most of the full-colour Hubble images released by ESA/Hubble, this image is a composite, made up of several individual snapshots taken by Hubble at different times and capturing different wavelengths of light. … A notable aspect of this image is that the two sets of Hubble data used were collected 23 years apart, in 2000 and 2023! Hubble’s longevity doesn’t just afford us the ability to produce new and better images of old targets; it also provides a long-term archive of data which only becomes more and more useful to astronomers.

All told, four Hubble data sets were used to produce the picture.

Oh no! Starship/Superheavy is loud!

9:21 am

Superheavy after its flight safely captured at Boca Chica
Superheavy after its October flight, safely captured at Boca Chica

Time for another Chicken Little report: A new study of the sound levels produced by SpaceX’s Superheavy booster during its fifth launch and landing at Boca Chica in October 2024 suggests that it produces more noise than predicted.

Overall … Gee et al. note that one of the most important conclusions from their data is the differences between Starship’s launch noise levels and those of SLS and Falcon 9. The team found that Starship produces significantly more noise at liftoff than both SLS and Falcon 9 in both A-weighted and Z-weighted (unweighted) noise metrics.

When compared to Falcon 9, the noise produced by a single Starship launch is equivalent to, at a minimum, 10 Falcon 9 launches. Despite SLS producing more than half of Starship’s overall thrust at liftoff, Starship is substantially louder than SLS. More specifically, one Starship launch is equivalent to that of four to six SLS launches regarding noise production. As has been hypothesized by numerous other studies into the noise produced by rockets, this significant difference in noise levels may be due to the configuration of first-stage engines on the rockets. For example, although the Saturn V produced less overall thrust than SLS, it produced two decibels more noise than SLS, which may be due to the clustered engine configuration on Saturn V’s first stage.

We’re all gonna die! Despite the doom-mongering of this study (which you can read here), the only issue noted by the paper from this noise was car alarms going off. And even here, the spread of the noise was asymmetrical, occurring in only one direction.

The concern about sonic booms has always been the annoyance they cause to residents near airports. In the case of Superheavy, it is very unlikely it will ever fly at a frequency to make its noise intolerable. More important, the nature of a spaceport versus an airport reduces the concern considerably, since a spaceport requires a much larger buffer area, and at both of SpaceX’s Starship launchsites in Florida and Texas almost everyone living close by works for the company or in the space business. They are not going to complain.

And while studying these noise issues is useful, we must not be naive about the real purpose of such studies. Underneath its high-minded science goals is a much more insidious one: finding a weapon for shutting down SpaceX. This concern of mine might be overstated, but remember, almost our entire academic community is rabidly leftist and made up of partisan Democrats. They hate Musk for his politics, and have been aggressively looking for ways to hurt him. This sound study is just another tool in that war.

The French cargo capsule startup The Exploration Company (TEC} announced today that it has raised an additional $160 million in private investment capital, bringing the total raised by the company to $230 million.

Venture capital firms Balderton Capital and Plural were the lead investors in the round which also included French government-backed investment vehicle French Tech Souveraineté and German government-backed fund DeepTech & Climate Fonds.

TEC’s core product is Nyx, a capsule that can be launched from rockets into space carrying passengers and cargo. Nyx is reusable so once it has dropped its payload, it can re-enter the Earth’s atmosphere and be used for the next mission.

The company hopes to do its initial test flight of Nyx in 2028. It flew a demonstrator prototype on the first Ariane-6 launch in July 2024, but was unable to test that prototype’s re-entry capabilities (its prime mission) because of a failure in Ariane-6’s upper stage. It hopes to fly a second demonstrator in 2025 on a Falcon 9.

At the moment company officials say they already signed $800 million in cargo contracts, 90% of which are with the commercial space station companies Axiom Space, Vast, and Starlab. The rest are government contracts.

SpaceX launches Australian geosynchronous communications satellite

3:37 pm

SpaceX today successfully placed an Australian geosynchronous communications satellite into orbit, its Falcon 9 lifting off from the Kennedy Space Center in Florida.

The rocket’s two fairings completed their 10th and 20th flights respectively. The first stage completed its 16th flight, landing on a drone ship in the Atlantic. At posting the satellite had not yet been deployed.

The leaders in the 2024 launch race:

115 SpaceX

NASA’s annual audit is not only not as great as NASA claims, it illustrates how the poison of DEI permeates the agency

3:43 pm

Not all is well at NASA
Not everything is as great as NASA claims

Yesterday NASA issued a press release proudly announcing that its annual independent audit of NASA’s finances concluded “for the 14th consecutive year … an unmodified, or ‘clean,’ opinion [of] its fiscal year 2024 financial statements.”

The rating is the best possible audit opinion, certifying that NASA’s financial statements conform with Generally Accepted Accounting Principles for federal agencies and accurately present the agency’s financial position. The audit opinion reaffirms the agency’s commitment to transparency in the use of American taxpayers’ dollars.

In reading the actual financial statements and auditor’s report (available here [pdf]), I found however that all is not “clean”, as NASA claims. Two issues of concern — one financial and the other political — are well buried in the report and should be quickly dealt with by the upcoming Trump administration.

Sloppy bookkeeping

First, the independent auditor, Ernst & Young, found that NASA’s internal control system designed to track spending was not quite up to par. From pages 90-91 of the report:

SpaceX delays 6th Starship/Superheavy launch one day to November 19, 2024

2:42 pm

In a tweet yesterday SpaceX announced that it is now targeting November 19, 2024 for the sixth orbital test flight of its Starship/Superheavy rocket. The thirty minute launch window opens at 4 pm (Central). Though SpaceX will provide a live stream on X, X does not provide a standby service, so I am embedding below the feed of SpaceX’s live stream provided by Space Affairs.

From SpaceX’s webpage for this mission:

The next Starship flight test aims to expand the envelope on ship and booster capabilities and get closer to bringing reuse of the entire system online. Objectives include the booster once again returning to the launch site for catch, reigniting a ship Raptor engine while in space, and testing a suite of heatshield experiments and maneuvering changes for ship reentry and descent over the Indian Ocean.

Starship’s landing will be in daylight this time in order to allow for better observation.

Orbital tug startup Impulse Space buys three SpaceX Falcon 9 launches

12:53 pm

The orbital tug startup Impulse Space announced yesterday that it has signed a contract with SpaceX for three Falcon 9 launches in order to fly its Helios orbital tug as well as its smaller Mira tug on several commercial missions.

The first launch, planned for mid-2026, will be the first flight of Helios. The transfer vehicle will transport the company’s smaller Mira vehicle, carrying a commercial optical payload, from low Earth orbit to geostationary transfer orbit on the Victus Surgo mission for the Space Force and Defense Innovation Unit. Impulse Space received a $34.5 million contract for Victus Surgo and another mission, Victus Salo, Oct. 3. Impulse Space said the schedule and payloads for the other two Helios launches will be determined later.

This development signals a major shift in the nascent orbital tug industry. Up until now the varous tug companies would buy launch space on rockets as secondary payloads. This I think is the first time a tug company has purchased the rocket itself as the primary payload, giving it the ability to control the rocket in order to make its tug operations more precise for all of its customers.

Rocket startup ABL abandons its effort to build a rocket

12:42 pm

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

10:27 am

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

10:11 am

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.

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

9:43 am

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

9:24 am

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

9:14 am

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.

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

8:54 am

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

8:36 am

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.

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

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

9:55 am

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

9:37 am

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

9:19 am

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

9:10 am

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

8:59 am

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

12:08 am

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.

A defunct satellite is now in an unexpected orbit, and no one knows how it got there

3:56 pm

Skynet-1A, a British satellite launched in 1969 and out of commission since the 1970s, has now been found in an unexpected location in geosynchronous orbit, and no one knows how it got there.

Launched in 1969, just a few months after humans first set foot on the Moon, Skynet-1A was put high above Africa’s east coast to relay communications for British forces. When the spacecraft ceased working a few years later, gravity might have been expected to pull it even further to the east, out over the Indian Ocean.

But today, curiously, Skynet-1A is actually half a planet away, in a position 22,369 miles (36,000km) above the Americas. Orbital mechanics mean it’s unlikely the half-tonne military spacecraft simply drifted to its current location. Almost certainly, it was commanded to fire its thrusters in the mid-1970s to take it westwards. The question is who that was and with what authority and purpose?

The article attempts to suggest the orbit change was done for some nefarious purpose, but the most likely explanation is that at some point the British engineers who operated it ordered the required engine burns, but the records of that work are now lost.

Though the present location poses some problems for other geosynchronous satellites, Skynet-1A also now offers a great opportunity for a mission demonstrating a way to clean up junk in these orbits.

China launches four remote-sensing satellites

3:47 pm

China today successfully launched four new remote-sensing satellites, its Long March 2C rocket lifting off from its Jiuquan spaceport in northwest China.

No word on where the rocket’s lower stages, which use very toxic hypergoic fuels, crashed.

The leaders in the 2024 launch race:

110 SpaceX
50 China
13 Russia
12 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 128 to 76, while SpaceX by itself still leads the entire world, including American companies, 110 to 94.
