ULA’s CEO outlines a bright 2025 for its Vulcan rocket

In an interview for the website Breaking Defense, ULA’s CEO Tory Bruno outlined his optimistic outlook in 2025 for its Vulcan rocket, despite the loss of a nozzle from a strap-on booster during its second test launch.

The important take-aways:

  • He expects the military to certify the rocket “momentarily”, though this could mean one to several months.
  • The company plans 20 launches in 2025, with 16 Vulcans already in storage.
  • Eventually Bruno expects to be launching 20 to 30 times per year.
  • Blue Origin has so far delivered 12 BE-4 engines, of which four have flown.
  • Blue Origin’s production rate is presently one per week.

The last two items are significant. If this production rate is the fastest Blue Origin can do, it will limit the number of Vulcan and New Glenn launches significantly per year. For example, Vulcan uses two engines per launch. To do 20 launches in 2025 will require 40 engines. Blue Origin however wants to also launch its New Glenn a number of times in 2025, and it uses seven BE-4 engines per launch. A production rate of one per week means that Blue Origin will not be producing enough engines for the number of launches planned for both rockets. Either ULA will have to delay its Vulcan launches awaiting engines, or Blue Origin will have to do the same for its New Glenn.

Of course, it is also possible that Blue Origin will be able to up this production rate with time. It has certainly made progress in this area in the past year, since a year ago it was having trouble producing one engine per month.

Part 1 of 2: What NASA’s next administrator should do if SLS and Orion are cancelled

When George Bush Jr. first proposed in 2004 an American long term effort to return to the Moon that has since become the Artemis program, he made it clear that the goal was not to simply land in 2015 and plant the flag, but to establish an aerospace industry capable of staying on the Moon permanently while going beyond to settle the entire the solar system.

The problem was that Bush proposed doing this with a government-built system that was simply not capable of making it happen. Though this system has gone through many changes in the two decades since Bush’s proposal, in every case it has been centered on rockets and spacecrafts that NASA designed, built, and owned, and were thus not focused on profit and efficiency. The result has been endless budget overruns and delays, so that two decades later and more than $60 billion, NASA is still years away from that first Moon landing, and the SLS rocket and Orion capsule that it designed and built for this task are incapable of establishing a base on the Moon, no less explore the solar system.

The real cost of SLS and Orion
The expected real per launch cost of SLS and Orion

For one thing, SLS at its best can only launch once per year (at a cost of from $1 to $4 billion per launch, depending on who you ask). There is no way you can establish a base on the Moon nor colonize the solar system with that launch rate at that cost. For another, Orion is simply a manned ascent/descent capsule. It is too small to act as an interplanetary spacecraft carrying people for months to years to Mars or beyond.

These basic design problems of both SLS and Orion make them impractical for a program to explore and colonize the solar system. But that’s not all. Orion has other safety concerns. Its heat shield has technical problems that will only be fixed after the next planned Artemis-2 manned mission around the Moon. Its life support system has never flown in space, has issues also, and yet will also be used on the next manned flight.

Thus, it is very likely that when Jared Isaacman, Trump’s appointee for NASA administrator, takes over running the agency, he will call for the cancellation of both SLS and Orion. How can he ask others to fly on such an untested system?

When he does try to cancel both however the politics will require him to offer something instead that will satisfy all the power-brokers in DC who have skin in the game for SLS/Orion, from elected officials to big space companies to the bureaucrats at NASA. Isaacman is going to have to propose a new design for the Artemis program that these people will accept.

Artemis without SLS and Orion

Before I propose what Isaacman should do, let’s review what assets he will have available within the Artemis lunar program after cancelling these two boondoggles.

Two congressmen demand FAA streamline its launch licensing process

In a letter [pdf] sent to the FAA on December 6, 2024, two congressmen have called for the FAA to fix what it calls its Part 450 launch licensing process, established in 2021, that has been choking off rocket development in the U.S.

The congressmen, Sam Graves (R-Missouri) and Rob Wittman (R-Virginia), specifically focused on the problems these new regulations have imposed during what the FAA calls its “pre-application review.” From the letter:

In November of 2024, the FAA indicated that 98 percent of applications are met within the statutory 180 day timeline. However, this timeframe does not include the months, and oftentimes years, of pre–application review that create extensive delays for companies seeking a launch and reentry license. [emphasis mine]

Consider the implications of this one quote. The FAA is proud of the fact that it approves license applications within six months — an ungodly long time for a startup — but doesn’t mention that the approval process is actually far longer because it requires new applications to be reviewed at length, before they can even be submitted.

In November, a week after Trump’s election victory, the FAA announced that it was forming a committee made up of people from the launch industry as well as academia to review Part 450. In their letter the congressmen approved of this new committee, but noted its work would not be completed until mid-2025, and that “the system is broken and must be fixed” immediately.

We, however, urge the FAA to act now and ensure that all actions short of rulemaking that can help mitigate the deficiencies of the part 450 regulation are taken in advance of any necessary regulatory changes to ensure that the commercial space industry does not have to wait years for relief.

I suspect we shall see some real action at the FAA come January 20, 2025, after Trump takes office.

AST SpaceMobile’s satellite-to-cell constellation gets its second contract

AST SpaceMobile, which is building a constellation of satellites that act as orbiting cell towers and can provide service where ground-based cell towers are unavailable, has now won its second contract, signing a 10-year deal with Vodafone, a European cell company which provides service there as well as across Africa and the Middle East.

AST’s first contract is with AT&T in the U.S. It already has five satellites in orbit, and plans to begin launching its second generation and larger BlueBird satellites next year, with the goal to begin service in the U.S. first.

All it needs really is an FCC license, which it has applied for but not yet received. Its main competitor, Starlink, has received its FCC license, so expect this red tape to evaporate relatively quickly, especially with the coming change in presidents.

One of Australia’s proposed spaceports moves

Australia's spaceports
Australia’s spaceports

“I’m from the government and I’m here to help!” Because of its inability to get the proper permissions from a local council, the management of Equatorial Launch Australia (ELA) has abandoned its original spaceport location on the Gove peninsula in the Northwest Territory of Australia and shifted east to a new location on the York peninsula in Queensland.

On the map to the right the “X” shows the old location, with the new location near the town of Weipa on the west coast of the peninsula. The change was forced on the company when it could not get proper approvals from the Northern Land Council (NLC), which manages the Arnhem Land Aboriginal Land Trust where the original site was located.

In a statement late on Monday, ELA said its most recent attempt to finalise a lease for the expansion of the ASC in October had been unsuccessful, following three other failed attempts in the last 12 months. In each case, it said the NLC had “failed to meet its own specified deadline for the approval of the Head Lease” or “provide any official reason for the delay”, despite pleas from the NT government and the Gumatj Aboriginal Corporation.

Because ELA has a launch contract with a South Korea rocket startup Innospace that intends to launch next year, it decided the switch had to occur now to make sure it could meet its obligations under this launch contract.

“Thar’s ice in them hills!”

Overview map

Thar's ice in them hills!
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on September 25, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the camera team labels as a “mound in the southern highlands.”

The mound in question sits in the center of the sunken depression, and at the highest resolution shows its top to be cracked and broken, as if something is attempting to break out by pushing up from below.

Everything about this picture screams near-surface ice. The cracked mound suggests ice sublimating into gas, which applies pressure to the surface and thus the cracks. The depression suggest that much of the near-surface ice at this location has already disappeared, causing the ground to sag. All the craters lack upraised rims. If caused by impacts, the ground here was soft enough that the impactor simply sank into the ground. Imagine dropping a rock you’ve heated into snow. It would simply leave a hole.

But there’s more. The white dot in the overview map above marks the location. In the inset, the lighter area surrounding this depression resembles an ice sheet that is slowly sublimating away. There are also other similar depressions in that lighter area. The lighter area also has fewer craters than the darker regions nearby, suggesting that this ice sheet covers the older impacts.

The location is in the southern cratered highlands in a mid-latitude region where many images indicate the existence of layers of ice deep below ground. This picture is more evidence of the same, but it also indicates the presence of ice very close to the surface as well.

The orbital data continues to tell us that Mars is not a dry desert like the Sahara, but an icy desert like Antarctica. There will be plenty of water for future colonists. All they will have to do is stick a shovel in the ground, dig it up, and process it.

SpaceX launches 23 Starlink satellites

SpaceX just after midnight (Eastern) tonight successfully launched another 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its second flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

128 SpaceX
59 China
16 Russia

American private enterprise now leads the rest of the world combined in successful launches 147 to 91, while SpaceX by itself leads the entire world, including American companies, 128 to 110.

Strange flat layers on Mars

Strange layers on Mars

Cool image time! The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on July 16, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what MRO’s camera team labels as “layers near ridge in Argyre Planitia.”

The layers are strange because there is so little topographic difference between them. Though the ground slopes downward from the south to the north, dropping about 1,300 feet, it does so almost smoothly. The layers show relatively little topographic relief.

And what caused the circular shape? Is it evidence of a buried crater? And if so, why so little relief at its rim?

As always, the overview map provides some answers.

Iran launches its Simorgh orbital rocket

Iran today announced it has successfully placed several small payloads into orbit, its Simorgh rocket lifting off from its interior Semnan spaceport.

The Simorgh carried what Iran described as an “orbital propulsion system,” as well as two research systems to a 400-kilometer (250-mile) orbit above the Earth. A system that could change the orbit of a spacecraft would allow Iran to geo-synchronize the orbits of its satellites, a capability Tehran has long sought.

It also carried the Fakhr-1 satellite for Iran’s military, the first time Iran’s civilian program is known to have carried a military payload.

This was Iran’s fourth launch in 2024, doubling the launch record it had set in 2023.

The leader board for the 2024 launch race remains unchanged:

127 SpaceX
59 China
16 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 146 to 91, while SpaceX by itself leads the entire world, including American companies, 127 to 110.

Hubble takes a different look at quasar 3C 273

Hubble's different views of 3C 273
Click for original image.

One of the most studied objects in the sky is the quasar 3C 273, located about 2.5 billion light years away and the first quasar ever to be identified, in 1963. What makes it especially interesting is the 300,000-light-year-long jet that shoots out from it.

Astronomers have now used the Hubble Space Telescope to take a different view of 3C 273, using the telescope’s coronograph to block the central bright light so that the surrounding dimmer features can be seen. The two images to the right, reduced and sharpened to post here, show what this new image (bottom) reveals when compared to an earlier Hubble image (top).

The new Hubble views of the environment around the quasar show a lot of “weird things,” according to Bin Ren of the Côte d’Azur Observatory and Université Côte d’Azur in Nice, France. “We’ve got a few blobs of different sizes, and a mysterious L-shaped filamentary structure. This is all within 16,000 light-years of the black hole.”

Some of the objects could be small satellite galaxies falling into the black hole, and so they could offer the materials that will accrete onto the central supermassive black hole, powering the bright lighthouse.

What makes this observation even more outstanding is that the image was produced by using Hubble’s Space Telescope Imaging Spectrograph (STIS) as the coronograph to block the bright center of 3C 273. This improvisation of STIS has been done many times before, but it remains a great example of clever thinking by the astronomers who use Hubble.

Japan’s space agency admits first launch of its new Epsilon-S rocket will be delayed

Japan’s space agency JAXA yesterday admitted that the first launch of its new Epsilon-S rocket — intended to be cheaper and competitive with the new rockets being developed worldwide — will be delayed because of the explosion that occurred during a static fire test on November 26, 2024.

The news reports in the Japanese press don’t provide much information. It appears the investigation into the explosion is still on-going, and that the cause of the failure has not yet been identified. Because of this, JAXA has been forced to cancel the planned March 2025 date for Epsilon-S’s inaugural flight.

JAXA should get out of the business of building rockets, as its track record is really horrible. The Japanese government has already told it to do so, but it is clearly dragging its feet, not wanting to give up the turf it has controlled for decades.

Why Orion’s heat shield problems give Jared Isaacman the perfect justification to cancel all of SLS/Orion

Orion's damage heat shield
Damage to Orion heat shield caused during re-entry in 2022,
including “cavities resulting from the loss of large chunks”

In yesterday’s press conference announcing new delays in NASA’s next two SLS/Orion Artemis missions to the Moon, agency officials were remarkably terse in providing details on why large chunks of Orion’s heat shield material broke off during its return to Earth in 2022 during the first Artemis mission. That damage, shown to the right, is one of the main reasons for the newly announced launch delays.

All they really said was that the damage was caused during re-entry, the atmosphere causing more stress than expected on the heat shield.

Today NASA finally released a more detailed explanation.

Engineers determined as Orion was returning from its uncrewed mission around the Moon, gases generated inside the heat shield’s ablative outer material called Avcoat were not able to vent and dissipate as expected. This allowed pressure to build up and cracking to occur, causing some charred material to break off in several locations.

…During Artemis I, engineers used the skip guidance entry technique to return Orion to Earth. … Using this maneuver, Orion dipped into the upper part of Earth’s atmosphere and used atmospheric drag to slow down. Orion then used the aerodynamic lift of the capsule to skip back out of the atmosphere, then reenter for final descent under parachutes to splashdown.

[Ground testing during the investigation showed] that during the period between dips into the atmosphere, heating rates decreased, and thermal energy accumulated inside the heat shield’s Avcoat material. This led to the accumulation of gases that are part of the expected ablation process. Because the Avcoat did not have “permeability,” internal pressure built up, and led to cracking and uneven shedding of the outer layer.

In other words, instead of ablating off in small layers, the gas build-up caused the Avcoat to break off in large chunks, with the breakage tending to occur at the seams between sections of the heat shield.

Europe’s Vega-C rocket returns to flight after being grounded for more than two years

Europe’s Vega-C rocket, built by the Italian company Avio but presently still managed by the European Space Agency’s commercial arm Arianespace, today successfully completed its first launch in two years, lifting off from French Guiana carrying a European Earth observation satellite. As of posting the satellite had not yet been deployed.

The rocket was first grounded when its upper stage failed during a December 2022 launch. The investigation pinpointed the problem as the design of the stage’s engine nozzle. However, the first redesign also failed, requiring a second redesign.

This was the eighth launch worldwide in the past 48 hours, the most ever accomplished in such a short time. All told, five nations completed launches (United States 3, China 2, India 1, Russia 1, Europe 1) from eight different spaceports, with all three American launches completed by SpaceX.

Because this was only the third launch by Europe this year, the leader board for the 2024 launch race remains unchanged:

127 SpaceX
59 China
16 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 146 to 90, while SpaceX by itself leads the entire world, including American companies, 127 to 109.

Next two Artemis missions delayed again, with the future of SLS/Orion hanging by a thread

Orion's damage heat shield
Damage to Orion heat shield caused during re-entry in 2022,
including “cavities resulting from the loss of large chunks”

In a press conference today, NASA officials admitted that their present schedule for the next two Artemis missions will not be possible, and have delayed the next mission (sending four astronauts around the Moon) from the end of 2025 to April 2026, and the next mission (landing astronauts on the Moon) to a year later.

It must be noted that when first proposed by George Bush Jr in 2004, he targeted 2015 for this manned landing. Should the present schedule take place as planned, that landing will now occur more a dozen years late, and almost a quarter century after it was proposed. We could have fought World War II six times over during that time.

Several technical details revealed during the conference:

  • It appears a redesign of Orion’s heat shield will take place, but not until the lunar landing mission. For Artemis-2 (the next flight), engineers have determined they can make the shield work safely by changing the re-entry path. They have also determined that the design itself is still insufficient, and will require redesign before Artemis-3.
  • Though Orion’s life support system will still be flown for the first time on Artemis-2, the first to carry humans, they have been doing extensive ground testing and have resolved a number of issues. They are thus confident that it will be safe to fly with people on its first flight.
  • Though SLS’s two solid-fueled strap-on boosters will be stacked for more than one year when Artemis-2 launches in April 2026, they are confident based on data from Artemis-1 that both will still be safe to use.

The political ramifications that lurked behind everything however are more significant.

Union official accuses Boeing of more unsafe practices

According Craig Garriott, a union representative at Boeing’s satellite-manufacturing facility in Los Angeles, Boeing’s management has been allowing numerous safety violations to go unfixed in order to focus on profits and fast production.

Acquired by Boeing in 2000, the satellite manufacturing facility has long been considered one of Boeing’s more stable business units. It relies in part on a union workforce that Garriott said is responsible for constructing and testing satellites and their component parts.

“This is perhaps the most technical group of hourly people that you’ll probably find on this planet,” said Garriott, who estimated he’s raised between 300 and 400 safety violations over the past year. Those complaints, he said, range from obstructed fire extinguishers and fire alarms to concerns over heavy machinery blocking exits and trapping workers in certain parts of the factory.

In October, union workers filed a complaint with the Occupational Health and Safety Administration that, according to Garriott, highlighted unsafe conditions on the factory floor. Another technician at the facility, who spoke to CBS News on the condition he remain anonymous to protect his job, said safety had become “an afterthought” and quality had “degraded” over the past five to six years.

It is important to recognize that Garriott’s complaints might simply be the typical tactic of a union representative during or before contract negotiations. There are rumors Boeing plans to sell off its space subsidiaries, which would include this satellite division. Garriott might simply be putting public pressure on the company in order to give himself a better negotiation position if such a sale takes place.

It is also quite possible, based on Boeing’s recent very poor track record in quality control, that everything Garriott says here is also true.

Sierra Space signs deal using its Dream Chaser mini-shuttles for in-space manufacturing

Sierra Space's family of planned LIFE modules
Sierra Space’s family of planned LIFE modules. Click for original

Sierra Space has now signed agreements with two different startups, Astral Materials and Space Forge, to use its Dream Chaser mini-shuttles for in-space manufacturing.

Astral Materials leverages the microgravity environment of space to grow ultra-high quality semiconductor crystals for advanced chip technologies. Space Forge harnesses free flying manufacturing facilities to produce next-generation materials for commercial industries, national security and research.

Up to now, Sierra’s only customer has been NASA, which wants to use Tenacity, the first Dream Chaser mini-shuttle, to hauling cargo to and from ISS. These new deals illustrate that there are other profit opportunities for the company’s reusable shuttle outside of government. As the startup Varda has already demonstrated with its own returnable capsule, there is money to be made manufacturing products in weightlessness that cannot be produced in the gravity of Earth.

The press release however has one additional tidbit that is intriguing. Sierra is a partner in the Blue Origin-led Orbital Reef commercial space station. It also appears to be the only partner that is actually building anything for that station, specifically its LIFE inflatable modules. The press release mentions that both these agreements include options for Astral and Space Forge to provide “input on Sierra Space’s future space stations.” That this press release does not refer to Orbital Reef here suggests once again that Sierra Space is somewhat dissatisfied with the output of its Blue Origin partner, and is thus creating options for it to build its own space station using those LIFE modules (shown above), should Blue Origin not deliver.

At a minimum, Astral and Space Forge will certainly be interested in doing manufacturing within those LIFE modules, should they end up being part of Orbital Reef.

Yuma competing for up to $160 million in an NSF grant to establish its own spaceport

Yuma spaceport

Arizona wants its own spaceport! The city of Yuma, located in Arizona’s southwest corner, is now a finalist in a National Science Foundation (NSF) grant program that could award it up to $160 million to establish a spaceport there.

The city is one of two Arizona applicants, the other being the University of Arizona, which wants to use the grant money “to make the state a proving ground for transformative mining technologies.” There are in addition 69 other applicants to the NSF grant.

This announcement is mostly PR, since Yuma not only does not yet have a spaceport licence from the FAA, it does not yet have approval from Mexico to fly missions over that country. Yuma is not on the coast, so launches must cross land. And if not over Mexico, launches would have to cross other U.S. states, something that would need approval as well.

This proposal has been in the works for many years, as having a spaceport in Arizona would draw a lot of space business to the state. It could happen, but to do so will require a lot of approvals from a lot of government agencies.

Another record-setting launch day worldwide

In what might be a record for the global launch industry, yesterday saw a total of four launches at four different spaceports worldwide.

That record might very well be matched today. Already three launches have already taken place, with one more scheduled.

First, India’s space agency ISRO successfully launched European Space Agency’s PROBA-XL solar telescope, its PSLV rocket lifting off from its Sriharikota spaceport on India’s eastern coast. This was India’s fourth launch in 2024.

Next, China launched what its state-run press merely described as a “group of satellites,” its Long March 6 rocket taking off from its Taiyuan spaceport in northern China. That state-run press also said nothing about where the rocket’s lower stages and four strap-on boosters crashed inside China. (UPDATE: More information about the payload can be found here. It appears to have been the third set of 18 satellites launched as part of China’s attempt to compete with Starlink.)

Then, SpaceX launched SXM-9, a new satellite for the constellation of the radio company Siruis-XM, its Falcon 9 lifting off from Kennedy in Florida. The first stage completed its nineteenth flight, landing on a drone ship in the Atlantic. As of posting the satellite had not yet been deployed.

If all goes as planned, the fourth flight today will be the first launch in more than two years of Avio’s Vega-C rocket, which has been grounded while the company redesigned and then redesigned again the engine nozzle of its upper stage. The launch is also one of the last that will be managed by Arianespace, which is giving up control to Avio over the next year. The live stream is here.

If successful, it will be the eighth launch worldwide in only two days, something that I am fairly certain has never been done before. In the past there simply weren’t enough independent entities and spaceports available to allow this number of launches in such a short period of time. What makes this record even more striking is that three of the eight launches were launched by one private American company, SpaceX.

The leaders in the 2024 launch race:

127 SpaceX
59 China
16 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 146 to 89, while SpaceX by itself leads the entire world, including American companies, 127 to 108.

Two more launches completed today

Since the first two launches earlier today, we have seen two more launches successfully completed.

First Russia placed a classified military payload into orbit, its Soyuz-2 rocket lifting off from its Plesetsk spaceport in northeast Russia. The fairings and first three stages all crashed inside Russia. No word if they landed near habitable areas, though the regions are generally sparsely inhabited.

Then SpaceX completed its second launch today, placing another 20 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg in California. Of the satellites thirteen were configured for direct-to-cell service. For the second time in the last week the company broadcast did not begin until after liftoff. In both cases the reason might be to avoid revealing any visuals of the rocket’s fairing, suggesting that SpaceX was using something different that it wanted to keep secret.

The first stage completed its twelfth flight, landing on a drone ship in the Pacific.

Not surprisingly, two of the launches previously scheduled for today have been postponed. The PSLV launch of a European solar telescope was delayed one day due to an issue detected with the payload’s propulsion system, while the first launch in two years of Arianespace’s Vega-C rocket was delayed because of an unspecified “mechanical issue.” At present Arianespace is targeting a launch for tomorrow.

The leaders in the 2024 launch race:

126 SpaceX
58 China
16 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 145 to 87, while SpaceX by itself leads the entire world, including American companies, 126 to 106.

The strange beginning of a 300-mile-long meandering canyon on Mars

Overview map

Today’s cool image will be unlike most cool images, in that we will begin not with the image but with the overview map to the right. The long meandering canyon at the center of this map is Nirgal Vallis, a 300-mile long canyon on Mars that eventually drains to the east into a much larger drainage system that runs south-to-north several thousand miles into the Martian northern lowland plains.

At first glance Nirgal Vallis invokes a river system. It starts in the west as several branches that combine to form a single major canyon meandering eastward until it enters that south-to-north system. To our Earth eyes, this canyon suggests it was carved by water flowing eastward, the many drainage routes combining as they flowed downhill.

Today’s the cool image, its location indicated by the white dot, tells us however that liquid water might not have been what created this canyon.

Trump picks billionaire and private astronaut Jared Isaacman to run NASA

Jared Isaacman
Jared Isaacman

Capitalism in space: In a decision that is certain to send shock waves throughout NASA and the established aerospace industry, President-elect Donald Trump today announced that he has chosen billionaire and private astronaut Jared Isaacman to be his nominee for NASA administrator.

Isaacman quickly accepted the nomination.

Besides being a jet pilot with extensive experience in the aerospace industry, Isaacman has also commanded two space missions, financed out of his own pocket. Both missions used SpaceX’s Falcon 9 rocket and Resilience capsule. Both also pointedly avoided any involvement with NASA, spending several days in free Earth orbit instead of docking with ISS. The second mission achieved several major engineering milestones, testing the first privately built spacesuit during a spacewalk while also flying farthest from Earth since the 1970s Apollo missions.

These flights were part of Isaacman’s own long term space program, dubbed Polaris, with two more missions already in planning stages. The first would be another Dragon orbital mission in which Isaacman had tried to get NASA to shape as a Hubble repair mission. NASA declined. The second is intended as a manned mission around the Moon using SpaceX’s Starship.

That program will now likely get folded into NASA’s Artemis program, which we can all expect Isaacman to force major changes. For one thing, this is another blow to the future of SLS and Orion. As a very successful businessman Isaacman will look with great skepticism at this boondoggle.

For another, Isaacman’s markedly different experiences working with SpaceX versus NASA will likely encourage major bureaucratic changes at the space agency. It is almost certain that Isaacman’s manned flights avoided ISS in order to avoid its Byzantine red tape, that would have likely also blocked use of SpaceX’s spacesuit on a private spacewalk. NASA’s decision to reject Isaacman’s proposal to do a simple but very necessary Hubble repair mission will also likely influence his management of the agency. Isaacman is going to force NASA to depend on the private sector more. He is also likely to reduce the agency’s risk adverse mentality that while often reasonable is many times very counter-productive.

Unlike many of Trump’s other radical nominees, I would be very surprised if Isaacman is not confirmed quickly and with little opposition.

Whether Isaacman will still fly his two remaining private Polaris manned missions is at this moment unknown. Practically it would make sense to cancel them, since he will have much bigger fish to fry at NASA. Emotionally and politically however it would be truly spectacular to have NASA’s administrator fly in space, on a mission using no taxpayer funds. That more than anything would demonstrate the ability of freedom and private enterprise to get things done.

Japan awards $32.5 million contract for lunar GPS-type satellite constellation to startup

Capitalism in space: As part of the multi-billion dollar fund the Japanese government has allocated to encourage private enterprise by new Japanese startups, its space agency JAXA has now awarded a $32.5 million development contract to the startup ArkEdge Space to design and fly a GPS-type satellite in orbit around the Moon, thus demonstrating the technology.

Under the agreement, ArkEdge Space will plan and design the mass production and operation of micro-satellite constellations to lead the development of a next-generation Lunar Navigation Satellite System (LNSS), a vital component to the International “LunaNet” initiative driven by National Aeronautics and Space Administration (NASA), European Space Agency (ESA) and JAXA. LunaNet seeks to establish essential infrastructure to support sustainable lunar exploration and foster the growth of the lunar economy.

The real significance of this contract award is that it signals JAXA’s growing shift from designing, building, and owning everything to simply becoming the customer who gets what it needs from the private sector. The Japanese government had established that fund for this express purpose, but JAXA has shown a reluctance to proceed, as it directly threatens its turf. This award indicates that reluctance is finally being pushed aside.

Orbex gives up on the Sutherland spaceport, switches to SaxaVord

Map of spaceports surrounding Norwegian Sea
Spaceports surrounding the Norwegian Sea

In a very sudden decision, the rocket startup Orbex, based in Great Britain, has “paused” its long-delayed work to develop a launch facility at the Sutherland spaceport in northern Scotland and instead decided to launch its first rockets from the competing SaxaVord spaceport on the Shetland islands.

Orbex says it is halting construction work on the £20 million spaceport and instead is mothballing the project, which has received a £14.6 million public investment package. The space company, which was to have made the Sutherland Spaceport its home port, will now launch its rockets carrying commercial satellites from another north spaceport – SaxaVord on Unst, Shetland.

According to the company’s CEO, it will retain its 50-year lease at Sutherland to give it “flexibility to increase launch capacity in the future.”

The company had originally hoped to launch its Prime rocket from Sutherland in 2022, but has been faced with red tape from the Civil Aviation Authority (CAA), which has still not issued a launch licence, even though the application was submitted almost three years ago. Orbex has also faced lawfare opposition from local activists as well as a major local landowner, billionaire Anders Povlsen, who is also a major investor in SaxaVord.

That last detail might help explain this decision. In private talks Orbex might have learned that the red tape and opposition would disappear if it switched to SaxaVord. The timing is also suggestive, as only a few days ago construction started on a new spaceport in Scotland, located on the island of North Uist.

All told, Orbex might have decided that the stars were aligned against it at Sutherland, and it was better to move. It now hopes to complete the first test launch of its Prime rocket from SaxaVord next year.

Two launches completed of the seven launches expected in the next 24 hours

Today will be one of the busiest ever at spaceports worldwide. Already we have had two launches, with five more expected by this time tomorrow.

First, China launched a radar satellite, its Kuaizhou-1A solid-fueled rocket lifting off from the Xichang spaceport in the southwest of China. No word on where the rocket’s lower stages crashed in China.

Next, SpaceX placed another 24 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida in the early morning hours. The first stage completed a record 24th flight, the most flights of any Falcon 9 booster so far, landing on a drone ship in the Atlantic Ocean.

And we are only getting started today. If all goes right, by this time tomorrow Russia will have done a military launch from its Plesetsk spaceport, Arianespace will have launched a Vega-C from French Guiana, SpaceX will have completed two more Falcon 9 launches from Vandenberg and Kennedy, and India will have launched its PSLV rocket from its Sriharikota spaceport.

The leaders in the 2024 launch race:

125 SpaceX
58 China
15 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 144 to 86, while SpaceX by itself leads the entire world, including American companies, 125 to 105.

SpaceX looking to raise more private investment capital

According to a report yesterday by Bloomberg, SpaceX is now in talks to raise more private investment capital, based on a new and vastly increased valuation of the company, from $255 billion to $350 billion.

A so-called tender or secondary offering, through which employees and some early shareholders can sell shares, provides investors in closely held companies such as SpaceX a way to generate liquidity.

The amount the company hopes to raise by this tender is at present not known. In the past decade the company has raised about $12 billion in private capital in order to fund development of both its Starship/Superheavy rocket as well as its Starlink internet constellation. The latter however is already generating about $9 billion in revenue annually in the past two years, more than enough to fund the projects.

PLD obtains a new loan, this time for $11.6 million

The Spanish rocket startup PLD yesterday announced it has obtained a new $11.6 million loan that it plans to use to build its launch facility at the French-owned French Guiana spaceport.

The loan was issued by the Spanish governmment finance agency COFIDES, which comes on top of an earlier $43.8 million Spanish government grant. In addition, the company has gotten a $2.4 million grant from the European Commission, as well as a $1.37 million grant from the European Space Agency.

The company has also obtained a loan of $34 million from banks in Spain.

All told, the company has raised about $164 million, more than $58 million came from government agencies, with another $34 million from loans.

For whatever reason, PLD has found favor with the various governments in Europe, fueling its work. None of the other European rocket startups from Germany or Great Britain have been as lucky.

Analysis of Chang’e-6’s lunar samples suggest the giant impact that caused Aitken Basin occurred 2.83 billion years ago

In a paper published in mid-November, Chinese scientists have concluded that — based on their analysis of the lunar samples returned by their Chang’e-6 spacecraft — the giant impact that created the 1,600-mile-wide South Pole-Aitken Basin on the Moon occurred about 2.83 billion years ago.

This conclusion is based both on the dating of the samples as well an analysis of the cratering rate on the Moon. It also suggests the landing site as well as Aitken basin were volcanically active for longer than previous predictions. Overall, scientists believe most volcanic activity on the Moon ceased around three billion years ago.

As noted in the paper, the near and far sides of the Moon are very different.

The Moon has a global dichotomy, with its near and far sides having different geomorphology, topography, chemical composition, crustal thickness, and evidence of volcanism. Volcanic eruptions flooded parts of the surface with lava, producing rocks known as mare basalts, which are more common on the nearside (4), where they cover ~30% of the surface compared to 2% of the farside.

The farside’s crust is also thicker, though under Aitken Basin the difference largely disappears.

This first precise dating for the far side is the first step for understanding why the Moon’s hemispheres are so different. Though many theories exist, none can be considered definitive because we so far have only one data point for the far side.

The uncertainty of science: Star refuses to erupt when predicted

Based on records of two past eruptions approximately eighty years apart, astronomers had predicted that the binary star system T Coronae Borealis would erupt sometime in September 2024, brightening from magnitude 10 to as much as magnitude 2, making it one of the sky’s brighter stars for a short while.

That eruption however has so far not taken place.

“We know it has to happen,” astrophysicist Elizabeth Hays, who is watching T CrB every day using NASA’s Fermi gamma-ray space telescope, told Space.com in a recent interview. “We just can’t pin it down to the month.”

The unpredictability stems partly from limited historical records of T CrB’s outbursts. Only two such eruptions have been definitively observed in recent history: on May 12, 1866, when a star’s outburst briefly outshined all the stars in its constellation, reaching magnitude 2.0, and again on February 9, 1946, when it peaked at magnitude 3.0. These events appear to follow the star’s roughly 80-year cycle, suggesting that the next outburst may not occur until 2026. [emphasis mine]

The eruptions are thought to occur because the system’s denser white dwarf star pulls material from the lighter orbiting red giant. Over time that material accumulates on the surface of the white dwarf until it reaches critical mass, triggering a nuclear explosion that we see as the star’s brightening.

Astronomers have assumed this process is predictable, but in truth it really is not. For example, the star has brightened at other times, in 1938 and again in 2015, though not as much. These other brightenings suggest a great deal of uncertainty in the rate in which material accumulates, as well as how much is needed to trigger a nuclear burst.

Because of the possibility however of a burst at any time, astronomers have been poised eagerly now for months, observing the star regularly with the many orbiting telescopes that can observe it not only in optical wavelengths but in gamma, X-rays, and infrared. The latter capabilities didn’t exist in previous eruptions, and are now able to tell them things about the system that was impossible for earlier astronomers.

Assuming the eruption occurs at all. Despite the certainty of the astronomer’s quote highlighted above, there is no certainty here. This star system will do whatever it wants, despite the predictions of mere human beings.

Varda wins $48 million Air Force contract

The U.S. Air Force last week awarded the reusable orbiting capsule company Varda a four-year $48 million contract for placing experimental hypersonic payloads on the capsule for testing during its re-entry through the atmosphere.

The four-year deal with AFRL [Air Force Research Laboratory], announced on Nov. 26, leverages Varda’s W-Series reentry capsules as platforms to test payloads at hypersonic speeds. The spacecraft are built on Rocket Lab’s Photon satellite bus,

…Varda’s next mission, W-2, is scheduled for early 2025. This mission is designed to showcase the Varda Hypersonic Testbed vehicle. The capsule will carry an AFRL-developed spectrometer payload named OSPREE (Optical Sensing of Plasmas in the Reentry Environment) to collect critical data during atmospheric descent.

Up until now Varda’s customers have been entirely focused on using the capsule to produce pharmaceuticals in weightlessness for sale back on Earth. This new contract provides it another and initially unexpected way to make money on the capsule’s capabilities.
