Starliner’s troubles were much worse than NASA made clear

11:51 am

Starliner docked to ISS
Starliner docked to ISS.

According to a long interview given to Eric Berger of Ars Technica, the astronauts flying Boeing’s Starliner capsule on its first manned mission in June 2024 were much more vulnerable than NASA made it appear at the time.

First, the thruster problem when they tried to dock to ISS was more serious than revealed. At several points Butch Wilmore, who was piloting the spacecraft, was unsure if he had enough thrusters to safely dock the capsule to ISS. Worse, if he couldn’t dock he also did not know if had enough thrusters to de-orbit Starliner properly.

In other words, he and his fellow astronaut Sunni Williams might only have a few hours to live.

The situation was saved by mission control engineers, who figured out a way to reset the thrusters and get enough back on line so that the spacecraft could dock autonomously.

Second, once docked it was very clear to the astronauts and NASA management that Starliner was a very unreliable lifeboat.

ESA isn’t forcing private companies building cargo capsules to hire contractors from all its partners

10:33 am

Capitalism in space: When the European Space Agency (ESA) in May 2024 awarded two contracts to the French startup The Exploration Company and the established Italian contractor Thales-Alenia to develop unmanned capsules for bringing cargo to and from orbit, it also made a major policy change that went unnoticed at the time.

During a press briefing on 23 May [2024], following the Phase 1 awards, ESA Director General Josef Aschbacher explained that the agency would not require participants in the initiative to adhere to its geo-return policy. The policy typically ensures that contracts are distributed among ESA member states in proportion to their financial contributions. “We contract very differently because we will be the anchor customer,” said Aschbacher. “That means we buy a service. We give industry all the freedom to find the best solution technically, but also the best partners, with whomever they want to work with.”

What means is that the two companies, in developing their capsules, have not been required to spread the work out across Europe. Instead, they have been free to do the work entirely in house, or hire just the subcontractors they prefer, from anywhere. As the CEO of The Exploration Company noted, “In plain terms, we choose our suppliers based purely on quality and cost—not because they’re French, Italian, or German. We choose the best supplier for the job.”

In the past, as part of its bureaucratic and political needs, ESA’s “geo-return policy” required every space project to spread the wealth to all of the ESA’s partner nations, in amounts proportional to their financial contributions to the ESA. The result was that every project went overbudget, took too long to complete, and was unrealistically complex. Many projects simply failed because of these issues. Others took decades to get completed, for too much money. And when it came to rockets, it produced the Ariane-6, that is too expensive and cannot compete in today’s market.

This decision last year means that ESA is very slowly adopting the concept of capitalism in space, whereby it acts merely as a customer, buying products that are completely owned and controlled by the seller.

This new policy presently only applies to the development phase of these capsules. Though no decision has been made about the construction phase, involving much more money, ESA publications indicate it will apply there as well.

Though it is taking time, Europe’s space bureaucracy is beginning to accept the idea of freedom and capitalism.

Fram2 passengers take their first pictures of Earth’s polar regions

10:10 am

The Arctic as seen from Fram2

SpaceX yesterday released a short video of the first pictures of the Earth’s polar regions taken by its Fram2 passengers on the capsule Resilience.

The picture to the right is a screen capture from that film, looking out the capsule’s large cupola window in its nose. The capsule’s nosecone can be seen at the bottom, having hinged sideways out of the way during orbital operations.

The tweet provided little information about the images. For example, it did not say which pole was imaged. Since the ground and ice below is dark, we are likely looking at the north pole, which at this time of year is mostly in shadow. You can see what looks like the edge of the ice pack, partly hidden by clouds.

The flight is scheduled to last from three to five days, and is presently in its second day. Not much information from the crew in orbit has at this point been released. I suspect they are simply enjoying their experience in private, since they are not obligated to share it with the world.

Another example of the weird taffy terrain in Mars’ death valley

1:29 pm

More taffy terrain

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

The scientists label it dimply as “layers in Helles Planitia.” Other scientists have given this strange landscape a much more interesting label, “taffy terrain.” It is found only in the Hellas Basin, the basement of Mars, having the lowest elevation found anywhere on the red planet. According to a 2014 paper, the scientists posit that this material must be some sort of “a viscous fluid,” naturally flowing downward into “localized depressions.” Because of its weird nature I have posted many cool images of it in the past (see here, here, here, here, and here).

Is taffy terrain still viscous, or has it become solidified? That question I think remains unanswered, though pictures taken of the same spot over time do not yet appear to show changes.

Sunspot update: NOAA scientists try to hide how wrong they have gotten things

12:00 pm

My monthly sunspot update today will have less to do with the Sun’s sunspot activity itself — which continues to show a very very slow decline from a peak in August 2024 — and more to do with more games-playing by NOAA solar scientists to fool the public into believing they know more than they do.

Below is my annotated version of NOAA’s monthly graph showing the amount of sunspot activity on the Earth-facing hemisphere of the Sun. This graph is significantly different from the graph that NOAA’s scientists have issued for the past few years, with all the changes designed to make it seem as if these scientists’ predictions are on the money, when they have been entirely wrong now for two solar cycles in a row.

Chinese man who used drone illegally over Vandenberg, spying for China, given slap on wrist in sentencing

9:19 am

Yinpiao Zhou, the Chinese man who flew a drone illegally over Vandenberg last fall in order to spy for China, has now been sentenced for his crime.

Yinpiao Zhou was sentenced Monday morning by a U.S. district judge in Los Angeles to four months in prison with a year of supervised released [sic]. He was also ordered to pay a $200 fine and $25 special assessment.

Since Zhou has been held in prison almost four months already, he will likely be released in days for time served.

All the evidence suggests he did this either willingly or unwillingly under orders from China. A second man that was with him while he flew the drone was never identified or arrested, and has likely been allowed to flee the country. Zhou himself tried to flee as well, as he was arrested at the airport as he tried to board a plane back to China. He is a Chinese citizen who is lawfully in the U.S., but having been caught spying it is astonishing that he is being allowed to remain in the country. He should be deported immediately.

Twenty years of Hubble data map one long season on Uranus

9:09 am

Uranus over twenty years
Click for original image.

Astronomers using the Hubble Space Telescope multiple times since 2002 have now tracked the changes in its atmosphere during one quarter of its 84 year orbit around the Sun.

The image to the right, reduced and sharpened to post here, shows Hubble’s views across several electromagnetic wavelengths. Uranus’s rotational tilt or inclination is almost 90 degrees, so that it literally rolls on its side as it orbits the Sun. You can see this especially in the bottom two rows. From 2012 to 2022 one pole slowly shifted westward. From the press release:

The Hubble team observed Uranus four times in the 20-year period: in 2002, 2012, 2015, and 2022. They found that, unlike conditions on the gas giants Saturn and Jupiter, methane is not uniformly distributed across Uranus. Instead, it is strongly depleted near the poles. This depletion remained relatively constant over the two decades. However, the aerosol and haze structure changed dramatically, brightening significantly in the northern polar region as the planet approaches its northern summer solstice in 2030.

Since we have not yet observed Uranus over one full year, there are a lot of uncertainties in any conclusions the scientists propose. For one, we don’t know the general atmospheric patterns across all four seasons. For another, any changes seen now might simply be the planet’s weather, random events not directly related to long term climate patterns.

SpaceX launches 28 Starlink satellites; China launches test internet satellite

8:39 am

SpaceX yesterday successfully placed 28 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

Thank you from several readers for letting me know that I missed it. This was the company’s first of two launches yesterday, the second of which was the Fram2 manned mission. I was so focused on that I missed the first.

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

China in turn today launched a satellite to test new technology for providing the internet from orbit, its Long March 2D rocket lifting off from its Jiuquan spaceport in China’s northwest. Little information was released about the satellite, and no information was released about where the rocket’s lower stages — using very toxic hypergolic fuels — crashed inside China.

The leaders in the 2025 launch race:

37 SpaceX
17 China
5 Rocket Lab
4 Russia

SpaceX now leads the rest of the world in successful launches, 37 to 30.

SpaceX launches four commercial private citizens on the first manned polar orbital mission

7:54 pm

Capitalism in space: SpaceX tonight successfully launched its Resilience capsule carrying four private citizens on commercial manned mission, its Falcon 9 rocket lifting off from Kennedy in Florida.

The first stage completed its sixth mission, landing on a drone ship in the Atlantic. Resilience in turn is on its fourth flight, with the last three all dedicated to commercial flights for private citizens.

The crew is made up of four rookie space-flyers, mission commander Chun Wang (who paid for the flight), vehicle commander Jannicke Mikkelsen, vehicle pilot Rabea Rogge, and mission specialist and medical officer Eric Philips. The plan is for them to stay in orbit from three to five days, circling the Earth in a polar orbit, the first time any humans have flown in space in such an orbit.

As always, the mission, dubbed Fram2 to honor Fridtjof Nansen’s Fram ship that explored the north pole region from 1893 to 1896, touts its many science experiments, but we should not fool ourselves. Its real goal is to provide Wang and his compatriots the thrill of flying in space.

That the flight is attracting relatively little press compared to previous private and NASA missions indicates how routine SpaceX is making its business. It is making space exploration profitable and no longer reliant on government funds. This is a big deal. Too bad most news outlets don’t realize it.

The leaders in the 2025 launch race:

36 SpaceX
16 China
5 Rocket Lab
4 Russia

SpaceX now leads the rest of the world in successful launches, 36 to 28.
