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,

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

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

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.

Sunspot update: Solar activity continues to decline as predicted

3:46 pm

Another month has passed, and so it is time for my monthly update on the never-ending sunspot cycle on the Sun. using NOAA’s own monthly update of its graph of sunspot activity and annotating it with extra information to illustrate the larger scientific context.

The green dot on the graph below indicates the level of sunspot activity on the Sun’s Earth-facing hemisphere during the month of October. Not only did the number of sunspots decline from the count in the previous month, as predicted in April 2025 by NOAA’s panel of solar scientists (as indicated by the purple/magenta line), it dropped below their prediction.

  • Lawmakers warn UK must act now to get space ambitions back on track
    The report, by the House of Lords, is a joke. It says nothing about reducing regulation and red tape, which is the UK’s main problem. Instead, it proposes more funding and more government bureaucracy “to coordinate policy and industry engagement.” We should expect even less (lower than zero?) from the United Kingdom in the coming years.

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.
