Crazy layers inside a Martian crater

Crazy layers in a Martian Crater
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on September 30, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists label this image with the term “layers”, but to my eye this is kind of an understatement. The geology in the top half of this picture is more than simply layers, it is an example of that unique Martian geological feature dubbed “brain terrain”, but on steroids.

No one yet knows what causes brain terrain, though scientists think it is related to the sublimation of near surface ice. Normally the tubelike formations are much smaller, only ten to thirty feet long, not hundreds of feet as we see here.

In this case the location of these features makes their formation even more puzzling, as there is no near surface ice found here.

Profits for Luxembourg satellite company SES drop due to U.S. budget cuts and shutdown

10:10 am

According to its third quarter report, the profits of Luxembourg satellite company SES were impacted negatively because of the budget cuts of the Trump administration, and were then further impacted because of the extended government shutdown.

Revenue over the first nine months of this year rose 20% to €1.75 billion while losses mounted to €55 million so far in 2025. Part of the problem was the Trump administration reassessment of spending that had been decided last year, including the delay of contract renewals and decisions on new awards, Chief Executive Officer Adel Al-Saleh said. Large contracts have also been delayed by the longest congressional budget standoff in US history, now in its sixth week, he said. “We’re experiencing timing delays in some contract awards due to the continuing resolution and subsequent government shutdown,” Al-Saleh said on a conference call with stock analysts.

The company remains in the black, and it expects to make up these losses from other customers. It is also in the process of completing its purchase of the satellite company Intelsat, which has also impacted its profits.

The article notes one interesting aspect of this Luxembourg company, that reflects the unique approach to tax dollars by that nation’s government: “Luxembourg taxpayers own one-sixth of SES shares, but wield a third of the voting power after underwriting its creation four decades ago.” The government doesn’t simply spend its tax revenue, like most governments. It treats that revenue as investment capital, and uses it to make money for the benefit of its citizens.

If only more governments would take this approach!

Webb tracks volcanic eruptions on Io

9:59 am

Different Webb infrared detections of Io over time
Click for original image.

Using the Webb Space Telescope, scientists have tracked two different volcanic eruptions on Io that too place from 2022 to 2023, detecting sulfur monoxide both from those eruptions as well as sulfur from the magnetic plasma torus produced as the planet travels through Jupiter’s strong magnetic field. From the paper’s abstract:

Volcanic thermal emission was detected from Loki Patera and Kanehekili Fluctus [two volcanic vents]. The main changes in the shape of the thermal emission spectra since [Webb] observed Io in November 2022 were consistent with the continued cooling of emplaced lava flows in the Kanehekili Fluctus region, and the crust that had formed on the surface of the lava lake in Loki Patera. Images of Io in the SO 1.707 μm emission band [sulfur monoxide] show a concentration above Kanehekili Fluctus and in two regions in the northern hemisphere. The emissions are sourced from SO molecules ejected from volcanic vents. We further detected, for the first time, sulfur line emissions at 1.08 and 1.13 μm. These emissions are distributed homogeneously across a band in Io’s northern hemisphere. They are mainly produced through excitation by electrons from the plasma torus, penetrating Io’s atmosphere.

The top image to the right shows the heat signature above the two volcanoes, one to the southwest and the second to the northeast. The middle image shows the sulfur monoxide emissions detected by Webb above those volcanoes from their on-going eruptions. The bottom image shows the more diffuse sulfur emissions, mostly in the northern hemisphere, believed produce by interactions with the plasma torus.

This research also relied on data obtained by both the Keck telescopes in Hawaii and the Hubble Space Telescope.

There are of course uncertainties with these results. For example, the conclusion that the more diffuse sulfur is produced by interactions with the plasma torus is not as certain. First, those sulfur emissions still appear closely linked to the volcanoes, which suggests this still could be a source.

Second, the observations also cover only two data points in time, in 2022 and 2023. To get a more precise map of the activity on Io we really need an orbiter there observing the planet on a continuous basis, something that is at this time impossible, not only because no mission is planned but because the hostile radiation environment this close to Jupiter makes the engineering quite challenging. It is this reason why Europa Clipper is not going into orbit around Europa when it arrives there in 2031. Better to orbit Jupiter and only periodically dip into that harsh radiation environment.

U.S. budget cuts shifts Blacksky’s satellite imaging business to international customers

9:24 am

Because of budget cuts by the Trump administration, the revenues of the satellite imaging company Blacksky fell in the third quarter of 2025, but the company expects to make up that loss with new income from international customers.

The administration’s fiscal 2026 budget proposal includes a one-third reduction to the National Reconnaissance Office’s commercial imagery procurement, a move that has rippled through companies like BlackSky that rely heavily on government intelligence contracts. The cuts specifically affect the Electro-Optical Commercial Layer (EOCL) program — an NRO initiative to buy satellite imagery from commercial providers.

BlackSky reported $19.6 million in third-quarter revenue, missing analyst expectations and down from the previous quarter. Chief Executive Brian O’Toole told analysts the reduction stemmed from adjustments to the company’s EOCL contract “to reflect the potential baseline budget submitted by the administration.”

Sound terrible, eh? Not so fast.

Despite the domestic headwinds, BlackSky is seeing a sharp uptick in overseas business. The company said international sales now account for about half of total revenue, up from 40% a year ago. O’Toole said foreign demand is “outpacing our U.S. government business” and that the company expects international sales to exceed U.S. sales for the first time in 2026.

Blacksky is of course blocked from selling its high resolution reconnaissance imagery to hostile powers, but there are plenty of American allies out there who want this data.

The situation is simple. When American companies are given the freedom to produce, they will create products of value. And the sky won’t fall if the federal government can no longer be their main customer.

Echostar sells more of its licensed spectrum to SpaceX

9:05 am

Echostar announced this week that it has sold additional spectrum that had been licensed to it by the FCC to SpaceX, getting in return about $2.6 billion in SpaceX stock.

EchoStar has entered into an amended definitive agreement with SpaceX to sell the company’s unpaired AWS-3 licenses for approximately $2.6 billion in SpaceX stock valued as of September 2025. This transaction builds on the agreement the companies entered into in September. EchoStar’s unpaired AWS-3 licenses are nationwide and are part of 3GPP Band 70n (1695-1710 MHz uplink). “This transaction with SpaceX, in addition to our previously announced spectrum transactions and commercial agreements, will strengthen EchoStar’s ability to develop new business opportunities and growth in value for our shareholders,” said Hamid Akhavan, CEO, EchoStar Capital. “The combination of AWS-3 uplink, AWS-4 and H-block spectrum from EchoStar with the rocket launch and satellite manufacturing capabilities from SpaceX accelerates the realization of powerful and economical direct-to-cell service offerings for consumers and enterprises worldwide, including our Boost Mobile customers.”

In other words, Echostar was not making any money from this spectrum on its own. By partnering with SpaceX it can do so, because SpaceX has the satellites and rockets capable of making it happen, and a cost that is affordable.

Nor should the companies have much problem getting FCC approval. Echostar had previously been accused of under-utilizing its licensed spectrum. This deal with SpaceX helps solve that issue.

In other Starlink news, SpaceX has begun rolling out Starlink service in India, while also striking a deal with British Airlines to use Starlink on its airplanes.

FAA issues a launch curfew due to the shutdown

10:31 pm

The Federal Aviation Administration (FAA) today issued a launch curfew that will ban all launches and re-entries from 6:00 am to 10:00 pm local time.

Accordingly, with respect to commercial space launches and reentries, under the authority provided to the FAA Administrator by 49 U.S.C. §§ 40103, 40113, and 46105(c), and authority delegated to the FAA Administrator under 51 U.S.C. § 50909(a), it is hereby ordered that, beginning at 6:00 a.m. EST on November 10, 2025, and until this Order is cancelled, Commercial space launches and reentries will only be permitted between 10:00 p.m. and 6:00 a.m. local time.

It appears the curfew has been imposed because of a shortage of air traffic controllers due to the government shutdown. Each launch needs to be coordinated with air traffic control, and it appears the FAA won’t have the people it needs to do this during the day. This is part of the overall 10% reduction in flights at forty of the busiest airports nationwide imposed at the same time, also due to the shutdown.

This order is going to probably impact planned launches by SpaceX, Rocket Lab, and others, with SpaceX likely affected the most.

Note: I got the curfew times backwards initially, and was corrected by my readers. Post is now correct.

One launch today by SpaceX, while ULA scrubs for the second time in two days

7:46 pm

SpaceX today successfully launched another 28 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.

The first stage completed its 8th flight, landing on a drone ship in the Atlantic.

ULA for the second day in a row was forced to scrub a launch of a Viasat communications satellite due to “a reoccurrence of the issue with the Atlas V booster liquid oxygen tank vent valve.” No new launch data has as yet been announced.

The contrast between these two rocket companies here is truly striking. In the past two days SpaceX’s reusable Falcon 9 has launched twice, like clockwork, while ULA can’t get off the ground because of a valve issue, the kind of niggling problem that routinely scrubs its launches. It is thus rare that ULA launches on time, on schedule, as planned.

SpaceX’s launch however sets a new record for successfully launches in a single year by the entire world, 257, breaking the record set last year. These numbers are two to five times what the global launch industry managed annually for most of the space age, and signal the renaissance in rocketry brought on by Elon Musk and SpaceX. Nor I think have we reached peak numbers. Not even close.

The leaders in the 2025 launch race:

145 SpaceX (a new record)
67 China
14 Rocket Lab
13 Russia

SpaceX now leads the rest of the world in successful launches, 145 to 112.

SpaceX and Arianespace make launch predictions for ’25 and ’26

9:40 am

In separate announcements this week, officials from Arianespace and SpaceX revealed their launch plans for the rest of this year and next.

First, Arianespace officials revealed yesterday that it is hoping to do six to eight Ariane-6 launches in 2026.

During a post-flight conference following the launch of Sentinel-1D, Arianespace CEO David Cavaillès stated that while the company preferred to wait until next year to reveal details about its 2026 launch manifest, it was aiming to double its launch cadence. He added that a cadence of between six and eight next year “will be great.”

If the company does manage eight Ariane 6 flights in 2026, it will already be close to reaching the stated maximum launch cadence of between nine and ten flights per year. When asked if this cadence could be increased, Cavaillès explained that the decision would be driven by customer demand.

Since customer demand for Ariane-6 has been quite low, because of its high cost, don’t expect this launch rate to rise much higher. Arianespace’s only big contract is 18 launches for Amazon’s Kuiper constellation. Once that is completed it is not clear where much future business will be coming from, even with some bureaucrats lobbying the European Space Agency to require its members to use it. There are too many cheaper options available now, with many more coming on line, both in America and Europe.

Next, a SpaceX official noted at a conference this week that the company hopes to complete another 25 to 30 Falcon 9 launches before the end of the year.

“We’re aiming for around 170 — between 165 and 170 — which means 25 to 30 more launches to go,” Kiko Dontchev, the company’s vice president of launch, said during a Wednesday session at the Space Economy Summit 2025.

…All together, “we’ll get to 2,400, 2,200 [metric tons launched] or something like that, which is absurd in the grand scheme of where things have been,” he added. Historically, that is close to the global record for metric tons launched to space by all companies and nations — about 2,500 metric tons in 2024, according to Jonathan’s Space Report, compiled by astronomer Jonathan McDowell.

In other words, SpaceX hopes its Falcon 9 rocket will this year alone place in orbit almost the same tonnage launched previously by everyone in the three-quarters of a century since Sputnik.

Cavaillès’ forecast means the company is likely to get very close to its prediction for launches at the beginning of the year, 180, that also included its Superheavy/Starship test launches. Quite an amazing achievement.

And as Al Jolson once said, “You ain’t seen nothin’ yet!”

China’s Tianwen-1 Mars orbiter snaps fuzzy picture of interstellar comet 3I/Atlas

9:22 am

Comet 3I/Atlas, as seen by China's Tianwen-1 Mars orbiter
Click for original image.

Chinese engineers have successfully taken a picture of interstellar comet 3I/Atlas as it passed its closest to point to Mars, about 19 million miles away, using their Tianwen-1 Mars orbiter.

The Tianwen-1 team began preparing for the observation in early September. After repeated simulations and feasibility assessments, they determined to use the high-resolution camera on the orbiter and designed optimal imaging strategies, ultimately achieving successful observation.

That image is to the right. Based on the fuzziness of the surrounding stars, the camera was not able to get a perfect focus during the observations. The main take-away is that the images once again prove 3I/Atlas is a comet not unlike those from our own solar system.

The mainstream press and some untrustworthy press-seeking scientists have tried to make a big deal about any interesting data point that has been observed from Comet 3I/Atlas, trying to claim it is some weird alien object of momentous importance. It is not. It is like every other solar system comet, though like those comets it is unique in its own way.

The big discovery here is how similar it is from solar system comets, suggesting that the processes that created our solar system are somewhat common throughout the galaxy.

State Department blasts the European Union’s proposed Space Act

9:06 am

The European Union
This label would be more accurate if it read
“NOT made in the European Union”

In a comment the State Department posted on November 4, 2025 on the European Commission’s website for public comment in connection with the European Union’s proposed Space Act, the Trump administration lambasted that law as imposing “unacceptable regulatory burdens on U.S. providers of space services to European customers.”

As a general matter, the United States expresses deep concern regarding measures in the proposed Act that would impose unacceptable regulatory burdens on U.S. providers of space services to European customers.

As close partners in civil, commercial, and security aspects of space cooperation for decades, the EU should proceed cautiously when developing and refining the proposed EU Space Act to ensure it provides a permissive and adaptable framework that promotes innovation, investment, and fair competition for the U.S., EU, and EU member states commercial sectors, while respecting each other’s sovereignty. Otherwise, the ability of the United States, the EU, and EU members to maintain government-to-government burden-sharing partnerships could be threatened. These non-tariff barriers would introduce challenges in the areas of space weather, remote sensing, space exploration, spaceflight safety, space debris mitigation and remediation, communications, as well as cooperations with the European Space Agency.

No one should be surprised by this response. Trump has always been aggressive in his desire to limit regulation. He has also been passionate about defending U.S. sovereignty. As I noted in June 2025 when the law was first released,

Starlab picks Leidos to assemble, integrate, and test its space station prior to launch

The consortium building the large single-module Starlab space station (intended to launch on Starship) yesterday picked the American company Leidos to assemble, integrate, and test its station prior to launch.

Leidos will assemble and integrate the components of Starlab’s space station into a complete system, supporting compatibility and verifying performance through environmental, functional and performance testing in Alabama. Additional responsibilities under the agreement include safety and mission assurance and systems engineering.

Since the consortium’s lead company, Voyager Space, raised nearly $400 million in its first public stock offering in June, Starlab has been signing up a lot of new partners, many of which like Leidos are aimed at building the station itself. First it signed the company Journey to design the station’s interior. Then it signed the Louisiana space hardware company Vivace to build Starlab’s primary structure. Next, a Belgium software company specializing in payload integration joined the consortium. Finally Voyager last week acquired the satellite electric propulsion company Exoterra. Initially I thought this last acquisition was aimed at increasing Voyager’s ability to win military contracts, but it also could provide the station itself with a system for orientation and propulsion.

All in all, this activity continues to strengthen Starlab’s position in the competition to win major contracts and customers leading to the construction of the station itself. Below is my updated rankings of the four commercial stations under development:

Two American launches today, setting several new launch records

8:58 pm

The beat goes on! Three different American companies attempted launches today, with two successfully getting off the ground while the third was forced to scrub due to an unspecified technical issue.

First Rocket Lab successfully launched another radar satellite for the Japanese company Q-Shu Pioneers (iQPS), its Electron rocket lifted off from one of Rocket Labs’ two New Zealand launchpads. This was the fifth launch out of a total eleven-launch contract that Rocket Lab has from Q-Shu. The launch also tied Rocket Lab’s record for the most successful orbital launches in a single year, 14, set in 2024.

Next, SpaceX launched another 29 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its fifth flight, landing on a drone ship in the Atlantic. The launch once again set a new annual launch record for SpaceX.

Only about two hours later, ULA attempted to launch a Viasat communications satellite using its Atlas-5 rocket, also lifting off from Cape Canaveral. At T-minus 4 minutes however there was an unplanned hold. After trouble-shooting the problem for almost an hour, they scrubbed the launch with only a few minutes left in the launch window. They will try again tomorrow.

With the two successful launches, the world’s global launch industry tied the record that was set last year for the most successful orbital launches in a single year, 256. That record will certainly be passed in the next few days.

What is more significant is that until 2020, the industry struggled to reach 100 launches per year. Since then the numbers have skyrocketed, led mostly by SpaceX’s overwhelming success.

The leaders in the 2025 launch race:

144 SpaceX (a new record)
67 China
14 Rocket Lab (tying its previous record)
13 Russia

SpaceX now leads the rest of the world in successful launches, 144 to 112.

This typical cliff on Mars just happens to match the walls of the Grand Canyon

A typical Martian cliff, comparable to the Grand Canyon
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 23, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The label the science team gave this image, “remnant fan”, suggests the focus of research here is the fingerlike ridges on the floor of the canyon, emanating out from the cliff. These appear to be the remains of an ancient mass-wasting event, similar to an avalanche but different in that instead of it being a pile of surface material falling down the cliff, the cliff itself breaks free and slumps downward. In this case the event was so long ago that most of the slumped material has eroded away, leaving only those ridges, likely resistant to erosion because of the impact of the material from above.

If you look at the top of cliff, you can see evidence that another mass wasting event is pending. Note how the plateau floor near the cliff has dropped about 100 feet. This drop suggests that this part of the cliff has started to slump and break away from the plateau.

Trump renominates Jared Isaacman for NASA administrator

8:51 am

Jared Isaacman
Billionaire Jared Isaacman

President Donald Trump late yesterday announced that he has renominated billionaire Jared Isaacman as his nominee to become the administrator of NASA.

Just as Trump had given no reasons why he had withdrawn Isaacman’s nomination in late May, in his announcement yesterday Trump made no effort to explain why he had changed his mind.

One week ago I would have said that Isaacman’s nomination would proceed very quickly to a vote in the Senate, as he had already been vetted completely in the spring and was fully expected to be confirmed within days when Trump pulled the nomination. Now however I expect the Senate might want to bring Isaacman back for questioning in response to the leak this week of a policy paper he had written in the spring outlining his plans for NASA should he be approved.

That paper, still not released to the public, apparently contained a lot of specifics about Isaacman’s plans to reshape NASA that appeared to raise the hackles of the many swamp creatures in DC that live off the government trough. Isaacman addressed that leak in a very long and very detailed tweet yesterday that outlined in detailed but general terms what his goals were in that paper, and it could be his reasoning in this tweet that convinced Trump to renominate him. As Isaacman concluded:

This plan never favored any one vendor, never recommended closing centers, or directed the cancellation of programs before objectives were achieved. The plan valued human exploration as much as scientific discovery. It was written as a starting place to give NASA, international partners, and the commercial sector the best chance for long-term success. The more I see the imperfections of politics and the lengths people will go, the more I want to serve and be part of the solution… because I love NASA and I love my country

These speculations however are all worthless. As we really don’t know the exact reasons why Trump pulled the nomination in May, it is difficult to guess why Trump changed his mind now.

It will be interesting to see how the Senate responds to this new Trump decision.

Arianespace launches European radar satellite

8:32 am

The commercial arm of the European Space Agency, Arianespace, yesterday successfully launched Europe’s Sentinel-1D radar satellite, its Ariane-6 rocket lifting off from France’s French Guiana spaceport.

As noted here,

The 2,184-kilogram Sentinel-1D satellite is a twin of Sentinel-1C, which was launched aboard a Vega C rocket in December 2024. Given that the Ariane 62 can deliver more than 10 tonnes to low Earth orbit, launching the 2.3-tonne Sentinel-1D on a dedicated flight appears excessive, particularly as its twin was launched on a Vega C rocket.

Officials claimed the reason was a need to get the satellite in orbit because one in orbit had failed, and because of the delay in Vega-C launches because of a launch failure. Since Vega-C however has fixed the nozzle issue that caused the failure and resumed launches, this argument is unconvincing. I suspect the real reason is that Arianespace has had problems getting customers for Ariane-6. Other than Amazon, which purchased 18 launches, European companies and nations have been generally reluctant to use Ariane-6 because it is too expensive (it is expendable).

This was only the fifth launch by Europe in 2025, so the leader board for the 2025 launch race remains unchanged:

143 SpaceX
67 China
13 Russia
13 Rocket Lab

SpaceX still leads the rest of the world in successful launches, 143 to 111.

China delays return of Shenzhou 20 crew due to possible capsule damage from “space debris”

11:02 pm

Shenzhou-16 after undocking in 2023
Shenzhou-16 after undocking in 2023. Click for source.

In a very brief statement today by China’s state-run press, it announced the planned return on November 6, 2025 of the Shenzhou-20 crew that has just completed their six month mission on the Tiangong-3 space station has been delayed indefinitely due to “a suspected impact from tiny space debris” on their Shenzhou capsule.

According to the statement “impact analysis and risk assessment are under way.”

A new crew arrived at the station on October 31, 2025 on the Shenzhou 21-capsule, and after a few days transition were to take over operations while the crew of Shenzhou-20 returned home.

We do not know the extent of the damage or even when it was first detected. Depending on the damage, China has several options. First, after review it could decide to return the crew on Shenzhou-20.

Second, it could decide that a fresh replacement capsule needs to be launched. If so, the old crew’s mission might be extended for a few months, as happened to a Soyuz crew on ISS in 2023 because of a leaking coolant system. First Russia launched a new empty capsule to ISS, and then the damaged capsule returned unoccupied. That way a lifeboat was always docked for that stranded crew.

It might also be possible to patch the damage, depending on its size and location.

In every case, the situation should not be critical. I am assuming the station is well stocked at this time, so that a crew of six instead of three could manage there for about three months. I am also assuming China has more Shenzhou capsules in the pipeline and can prepare a new one relatively quickly. Finally, I am also assuming China’s Shenzhou capsules can dock autonomously, as do their unmanned Tianzhou freighters.

And then again, if any of my assumptions are wrong, this situation could become more serious.

Someone is apparently considering putting a helicopter on Starship when it goes to Mars

2:53 pm

Potential Starship helicopter location

In my regular trolling through the images sent down from Mars Reconnaissance Orbiter (MRO), I sometimes come across things that imply truly exciting future missions. That happened when in 2019 I found a bunch of photos each labeled as a “candidate landing site for SpaceX Starship”. Without fanfare SpaceX had begun researching locations for where it intended to land Starship on Mars, in the northern lowland plains, research that it later solidified considerably.

Similarly, I have found MRO images in 2022 suggesting scientists were thinking of running a helicopter mission inside Valles Marineris, the largest canyon in the solar system. Another image in 2024 suggested that a helicopter mission might go to another region in Mars’s southern cratered highlands.

The image to the right, cropped, reduced, and sharpened to post here, is another new example of a potential Martian helicopter mission. It was taken on August 19, 2025 and is labeled provocatively “Characterize Possible Rotorcraft Landing Site.” Unlike the previous two proposed helicopter locations, however — which appeared to be aimed at uncertain NASA funding — this image’s location suggests it is far more certain, and might launch far sooner than you can imagine.

More Washington shenanigans over who will be NASA’s next administrator

12:17 pm

Two news outlets in the past day (Politico and Ars Technica) have posted stories about a 62-page plan — supposedly written by Jared Isaacman while he was still the nominee to become NASA administrator — that was recently leaked to them as well as others inside and outside NASA.

The plan itself, dubbed “Project Athena”, has not been made available, though the descriptions at both sources suggest it matches closely with the overall Trump effort to cancel SLS and Orion and shift space operations out of NASA and more into the private sector.

The nature of this plan of course threatens NASA’s established work force and the big space contractors who have worked hand-in-glove with NASA for decades, producing little but distributing a lot of money and jobs to these groups. Not surprisingly, both news sources quote extensively from anonymous sources within that NASA work force and those big space contractors, lambasting the plan and blasting Isaacman for proposing it. From the Politic article:

Sean Duffy
Sean Duffy: “Pick me! Pick me!”

Putting all of these plans into writing is a “rookie move,” and “presumptuous,” said an industry insider who has seen the document and thought it would stoke congressional skepticism around his nomination. Many of these ideas would need congressional approval to enact, and Congress could always block them.

The Ars Techica article speculates that interim NASA administrator Sean Duffy was the source of the leak, in his effort to become NASA’s official administrator. If the plan is Isaacman’s, it generates opposition to renewing Isaacman’s nomination as NASA administrator while garnering support for Duffy from NASA’s workforce and those big space contractors.

All of this is pure Washington swamp, however, which really matters little in the long run. First of all, none of this is real. We are talking about an unreleased plan that no one has seen publicly, and the reactions of anonymous sources criticizing that unseen plan. It is all the stuff of ghosts and fantasy. For we know, it is all made up, just like the Russian collusion hoax was manufactured against Trump.

Second, and more important, who runs NASA next is becoming increasingly unimportant. » Read more

Intuitive Machines buys Lanteris, formerly Maxar

11:05 am

The lunar lander startup Intuitive Machines today continued its diversification into other space fields by acquiring the long-established satellite and spacecraft manufacturer Lanteris, formerly known as Maxar, for about $800 million.

The transaction is priced at $800 million, consisting of $450 million in cash and $350 million in Intuitive Machines Class A common stock, subject to adjustment. The transaction is expected to close in the first quarter of 2026, subject to customary regulatory approvals and closing conditions. As a stand-alone company, Lanteris is a cash generating business. As a combined company, Intuitive Machines expects to have adequate cash on hand for continued operations.

Intuitive Machines has attempted two lunar landings, both of which were failures when its lander fell over at touchdown. Since then it has made a concerted effort to diversify into other areas, including developing a returnable capsule, Zephyr, a lunar manned rover, Moon Racer, and an orbital tug. It has also acquired KinetX, a company specializing in space navigation and communications.

This new acquisition positions the company to bid on a much wider range of space projects, including military contracts relating to its Golden Dome project that is expected to cost billions.

First unmanned test flight of India’s Gaganyaan capsule likely slips to next year

9:47 am

Artist rendering of India's Gaganyaan capsule
Artist rendering of India’s Gaganyaan capsule

Though India’s space agency ISRO still insists it will attempt the first unmanned orbital test flight of its Gaganyaan capsule before the end of 2025, its chairman has also indicated this schedule might slip into early next year due to agency’s upcoming launch schedule.

The problem is that it only has one launchpad for its largest rocket, LVM3 (recently nicknamed Bahubala) that Gaganyaan must use, and it has a contract with the American satellite company AST SpaceMoble to use Bahubala to launch one of its satellites next month. Furthermore, a Bahubala launch just occurred on that pad two days ago to launch a communications satellite for the Indian government. Thus, to do both the AST and Gaganyaan launches by the end of this year would mean it would have to do three launches from that pad in less than two months, something ISRO has never done.

ISRO plans to do at least three unmanned test flights of Gaganyaan before it attempts a manned orbital mission in 2027. If the first mission is slips into 2026, next year will be a very active one for ISRO, more active than that agency has been since it shut down during COVID.

Based on the present schedule, it appears that ISRO will set a pace of about one Bahubala launch every two months to complete this schedule, with the first Gaganyaan launch occurring around February 2026, and the next two Gaganyaan test launches in summer and fall. That would set the stage for the manned mission in early 2027.

MDA invests $7 million to become part owner of proposed Nova Scotia spaceport

9:29 am

Proposed Canadian spaceports
Proposed Canadian spaceports

The Canadian space company MDA Space has now purchased for $10 million ($7 million in U.S. dollars) a part ownership in the proposed Spaceport Nova Scotia that the startup Maritime Launch Services (MLS) has been trying to establish since 2016, with little success.

The transaction includes an Investor Rights Agreement, entered into between MDA Space and Maritime Launch, providing MDA Space with certain rights, including the right to nominate one individual to sit on the board of Maritime Launch and pro-rata participatory rights in future financings of the Spaceport. The investment will be used for applicable research and development initiatives relating to the ongoing development of Spaceport Nova Scotia and will trigger the retirement of convertible debentures.

The history of this spaceport has been a frustrating one. Originally it had partnered with a Ukrainian rocket company, proposing to offer satellite companies both the launch facilities and the rocket. That plan died in 2022, when Russia invaded the Ukraine and the rocket company switched from making rockets to making drones.

MLS then opened up Spaceport Nova Scotia to all rocket companies, hoping the new launch startups building portable small rockets that could be set up anywhere would buy in. Though it periodically announced deals, none were with established orbital companies. Some were startups that after years have yet to launch, such as the British company Skyrora. Other contracts were with startups that weren’t even rocket companies, such as the space station startup Voyager Space.

Meanwhile, a second spaceport startup, Nordspace, appeared in 2022, proposing a spaceport in Newfoundland dubbed The Atlantic Spaceport. While it has not launched anything either, it has quickly signed contracts for ground stations and a mission control center, and even attempted (though scrubbed) a launch of its own rocket.

Whether this new deal can finally get Spaceport Nova Scotia off the ground remains very uncertain. MDA is not a launch company. It is a long established satellite company that also builds the robot arms used on ISS.

China will launch its upgraded manned Mengzhou-1 capsule in 2026

8:01 am

Mengzhou as of 2023

China this week revealed that it plans the first flight of its new larger Mengzhou-1 manned capsule next year, launching from its coastal Wengchang spaceport on its new Long March 10 rocket.

Mengzhou features a modular design consisting of a return capsule and a service capsule and will operate as the primary link between Earth and the space station.

The first flight of Mengzhou-1 will utilize the Long March-10A rocket from the Wenchang Space Launch Site in Hainan, targeting a docking with the space station’s core module radial port. This debut mission will validate the craft’s systems while transporting environmental monitoring devices, technical payloads, astronaut supplies, and experimental gear for science and technology demonstrations.

Both capsule and rocket are intended as China’s future mainstays for its manned program, both in Earth orbit and beyond. Mengzhou is intended as the manned capsule that will get its astronauts to lunar orbit, where its Lanyue lunar lander will take them to and from the surface. Both will be launched separately by the Long March 10 rocket.

Long March 10 has been in development since 2017, and will have the ability to place 70 tons in low Earth orbit and 27 tons to lunar orbit. It is thus comparable to SLS, but costing far less with its first stage incorporating recovery and reuse. It will also be capable of launching much more frequently and at a much faster pace.

A think tank releases its detailed review of the American satellite communications industry

11:09 am

The state of the satellite constellation industry
Go here and here for originals.

Link to the press release is here. To read the actual report go here.

The report was issued by the LEO Policy Working Group, which calls itself “an independent body dedicated to providing forward-looking, data-driven analysis and policy recommendations to ensure the successful and sustainable deployment of next-generation Low Earth Orbit satellite systems.” In reviewing the membership of this group, I noticed that only one member appeared drawn from the industry itself (a former OneWeb advisor). The rest of the members were from lobbying groups, government agencies, academia, or DC think tanks.

Thus, I immediately wondered if this report was aimed against SpaceX and its present dominance, designed to justify further government regulation against it.

In reviewing the report however it does not seem so, at least on the surface. The report very accurately and detail describes the present state of the industry and all the players, including all the present constellations in orbit or under construction. It also describes the state of the launch industry on which they depend, including the risks entailed by SpaceX’s present dominance. At the same time it also notes at length that there is no evidence that SpaceX is doing anything to take advantage of that dominance.

Its recommendations are generally vague, and can be summed up simply as “Government should remain vigilant but do nothing drastic at this time.”

The report’s main benefit however its overall summary of the industry, as well as its detailed description of how the spectrum is regulated by government agencies.

Is the German government holding up Rocket Lab’s purchase of German space communications company Mynaric?

10:08 am

Even though Rocket Lab announced in March that it was acquiring the German laser communications company Mynaric for $150 million, and entered into the stock purchase agreement in September, the company has not yet gotten approval for the purchase from the German government, raising questions that approval might be denied.

A central question for regulators and industry observers is whether Mynaric, once owned by Rocket Lab, would still be deemed a European entity — a status that could determine its eligibility to compete for Europe’s planned sovereign communications network, known as IRIS² (Infrastructure for Resilience, Interconnectivity and Security by Satellite). The multibillion-euro program, backed by the European Union, is designed to strengthen Europe’s independence in secure satellite communications and may restrict participation to European-controlled firms.

Those regulators however also have to consider whether IRIS will even fly. Designed to provide a government option to the internet constellations being operated or built by Starlink, Kuiper, and several Chinese projects, it is significantly delayed, vastly over budget, and unlikely to compete very successfully. There have been rumors several EU nations are even balking at building it at all.

If Rocket Labs’ purchase of Mynaric is denied, it will likely not harm that company significantly. It will however be another example of Europe cutting off its nose to spite its face. It will block this American company from providing business to Europe, even as its own government projects wither on the vine.

Update on Vast’s first planned space station, Haven-1

9:51 am

Haven-2
Haven-2 station once completed

Link here. The article essentially puts together a number of X links that Jay has provided Behind the Black previously in his daily Quick Space Links reports to provide an overall picture. Two aspects stand out however.

One, the demo Vast launched this weekend on SpaceX’s bandwagon mission is expected to fly for about six months, and has successfully deployed its solar panels. During its flight the company will “test out key capabilities, such as Reaction Control Systems (RCS), power systems, and propulsion, in preparation for Haven-1”, which it hopes to launch in the spring.

Two, Haven-1’s planned mission remains unchanged. The company still intends to fly four crewed missions to it during its three-year mission, though who will make-up the crew and passengers remains unknown. This single module station is aimed at proving Vast’s capabilities at space station design and operation to convince NASA to award it a much larger contract to build its much larger Haven-2 multi-module station.

Max Haot [Vast’s CEO] described Haven-1 as the “minimum viable product”. With its one docking port and reliance on a SpaceX Crew Dragon for key life support systems, the station will enable the company to test out capabilities needed for larger stations in the future. The Dragon spacecraft requires a daily change of its CO2 scrubber; therefore, the station will launch with the necessary amount needed for 30-40 days on station for four astronauts.

All in all, Vast appears to be strongly demonstrating its capabilities, on schedule, making my listing it number one as most likely to win that big NASA contract increasingly correct. That ranking is made even more reasonable with the decision by NASA to now award several of those contracts, at smaller amounts, in a step-by-step process that matches milestones. Below is my updated rankings of the four commercial stations under development:

China launches “remote sensing” satellite, setting a new national record for annual launches

9:26 am

China early today successfully placed what its state-run press described as a “remote sensing satellite” aimed at Earth observations, its Long March 7 rocket lifting off from its Wenchang coastal spaceport.

The only thing that state-run presssaid was the satellite would “primarily [be] used in disaster prevention and relief, land resource surveys, hydrology, meteorology, and other related fields.” As for the launch, this was a coastal launch, with the rocket’s lower stages landing in the ocean.

This launch was the 67th for China in 2025, which breaks the annual record of 66 it set in 2023. As China tends to bunch more launches in the last two months of the year, expect it to add at least ten to this number.

The leaders in the 2025 launch race:

143 SpaceX
67 China (a new record)
13 Russia
13 Rocket Lab

SpaceX still leads the rest of the world in successful launches, 143 to 110.

Two overnight launches

9:24 am

The beat goes on: Since yesterday there were two more successful rocket launches, from India and SpaceX.

First, SpaceX last night launched its fourth Bandwagon mission carrying 18 mid-sized smallsat payloads, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its third flight, landing back at Cape Canaveral. The fairings completed their 11th and 13th flights respectively.

Bandwagon rideshare missions are dedicated missions by SpaceX. SpaceX’s SmallSat Rideshare Program provides small satellite operators with regularly scheduled, dedicated Falcon 9 rideshare missions to mid-inclination orbits for ESPA-class payloads, starting at $300,000 per mission and including up to 50kg of payload mass.

Among these payloads two were most notable, a South Korean military surveillance satellite and a demo module for the space station startup Vast. With the latter, the company will use this unmanned orbiting prototype to test operations to prepare for the launch in the spring of its full-sized manned demo station, Haven-1.

Next India’s space agency ISRO today launched its largest rocket, LVM3, lifted off from its Sriharikota spaceport, carrying the heaviest payload India had yet launched, a government communications satellite.

It appears the LVM-M3 has finally be given a real name. Previously ISRO called it the Geosynchronous Launch Vehicle (GSLV). When it was upgraded to a more powerful version intended for India’s manned program, the name was revised to LVM3 (Launch Vehicle Mark 3). News reports today referred to the rocket now as Bahubali, calling it a “nickname.”

In all of ISRO’s missions the agency routinely uses very generic official names, but appears to eventually accept nicknames that the press uses, such as Chandrayaan for its moon missions, Mangalyaan for its Mars orbiter, Gaganyaan for its manned missions, and now Bahubali for this rocket. Increasingly however the Modi government seems to be pushing to use these names instead of those generic titles.

This was India’s third launch in 2025. The leaders in the 2025 launch race:

143 SpaceX (a new annual record)
66 China
13 Russia
13 Rocket Lab

SpaceX now leads the rest of the world in successful launches, 143 to 109.

ISS study suggests that weightlessness impacts the eyes of men more than women

10:50 am

Eye flattening while in space
Astronauts who experienced changes in their
eyes (SANS) while on long missions in space

The uncertainty of science: A recent study of 30 astronauts during long term stays on ISS suggests that weightlessness impacts the shape of the eyes more in men than in women.

You can read the paper here.

In addition to changes in fluid around the brain, the team also found that a form of eye compression, a hallmark of Spaceflight Associated Neuro-ocular Syndrome known as globe flattening, was the most consistent eye change among crew members. “By far the most prevalent sign of eye changes that we observed was globe flattening, suggesting that this should be the primary monitoring target for ocular health,” Seidler said. “Interestingly, eye changes were more prevalent in males than females.”

Globe flattening, when the back of the eyeball becomes slightly indented or pushed inward, might sound minor, but it can have significant effects on vision and raise concerns for long-duration space missions.

Surprisingly, there was no strong link between brain structural changes and eye changes, suggesting that the effects on the eyes and brain may arise from distinct mechanisms rather than shared physiological cause

For the eye research, the sample was so small, 28 individuals of which only 9 were females, the researchers readily admit in their abstract that and “interpretation of these findings should be tempered by the fact that our sample included a relatively small number of females.” Nonetheless, the research did suggest that, regardless of sex, about half of all humans will experience these eye issues during long missions in weightlessness.

The results underscore the need to do artificial gravity experiments in orbit, to find out the minimum amount of gravity needed to mitigate or even eliminate these health issues. Otherwise, interplanetary travel is going to be seriously hampered, if not impossible.
