Cool image time! The picture to the right, cropped, reduced, sharpened, and brightened to post here, was taken on May 1, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists label this very simply as a “wall on Ausonia Cavis”. Ausonia Cavis — 31 miles long and 20 miles wide at its widest — is one of the many gigantic sinks found in many places on Mars. This particular cliff wall is about 2,000 feet high, though from rim to floor of the sink is closer to 3,000 feet.

The image was likely taken to get a closer look at those gullies flowing down the cliff wall. Previous research of similar cliff walls in this region has found what appears to be seasonal water frost in such gullies, and this image was likely taken to see if more such frost could be spotted here as well.

France government invests big in Eutelsat-OneWeb

According to the satellite company Eutelsat-OneWeb, the French government has now committed more than a billion dollars in investment capital to the company, doubling its stake to almost 30%.

France would more than double its stake in Eutelsat to nearly 30% as part of a $1.56 billion capital raise backed by multiple shareholders, bolstering the French operator’s plans to refresh its OneWeb constellation amid Starlink’s growing dominance.

The funds would be raised in two parts before the end of the year, Eutelsat announced June 19, a day after the French military agreed to buy OneWeb services over 10 years in a deal potentially worth up to one billion euros ($1.15 billion).

OneWeb itself almost went bankrupt until it was saved by cash from a major Indian investor and the government of the United Kingdom. This new deal means that the merged company is largely controlled by France, the UK, and India.

Chinese pseudo-company Landspace completes static fire test of 1st stage of its Zhuque-3 reusable rocket

The Chinese pseudo-company Landspace today successfully completed a static fire test of 1st stage of its Zhuque-3 reusable rocket, firing all nine engines for 45 seconds.

This lays the groundwork for the first launch attempt of this rocket.

The first Zhuque-3 orbital launch attempt was earlier slated for the third quarter of the year and would carry a prototype of the reusable Haolong cargo spacecraft, designed by the Chengdu Aircraft Design Institute under the Aviation Industry Corporation (AVIC). The test is part of a program for low-cost cargo delivery to the Tiangong space station. Landspace did not provide a timeframe for the launch in its static fire test statement.

It appears increasingly that three different Chinese pseudo-companies are getting close to launching reusable rockets within the next year or so. In addition to Landspace, there is CAS-Space (the rocket division of a government agency) and Space Pioneer. In addition, there five other pseudo-companies doing similar rocket hop tests. All are working under the supervision of the government, which requires them to share data.

India transfers ownership of SSLV rocket from space agency to government-owned private aerospace company

Capitalism in space: As part of the Modi government’s effort to switch its space industry from something owned and run entirely by its space agency ISRO, it has now awarded the ownership and control of ISRO’s newest and smallest rocket, the SSLV, to the aerospace company Hindustan Aeronautics Limited (HAL).

The company paid about $60 million for the purchase, and the right to build, market and launch it. It hopes to build between 6 to 10 rockets per year, depending on launch demand.

This transfer is not as radical as it appears. Though HAL operates mostly as an independent aerospace company, it is still owned by the government with its board of directors appointed by the president of India. The rocket will thus still be owned and controlled by the government, not a private company.

At the same time, this deal acts to shift power away from the space agency ISRO, which I suspect is the plan: Divvy up ISRO’s assets, which will eventually make it harder for it to block independent operations by private companies. As part of that program, the government has also transferred construction of the larger PSLV rocket from ISRO to a consortium of companies.

Whether this shift can create an independent and competitive rocket industry in India is very unclear. In many ways the country’s strategy so far mimics more China’s pseudo-company approach (where the companies raise investment capital, compete for government and commercial contracts, but are always under the full control and supervision of the government) then it does America’s free enterprise system (where ownership and control resides entirely with the companies, and the government only buys the services it needs from them).

The American model is by far the most successful in encouraging innovation and competition for the least cost. The Chinese model produces some results for less cost, but relatively little innovation. Instead, it copies what Americans do.

China launches communications satellite

China today successfully launched a communications satellite, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China.

As is usual for its state-run press, no information was provided about the satellite or where the rocket’s lower stages crashed inside China.

The leaders in the 2025 launch race:

76 SpaceX
35 China
8 Rocket Lab
7 Russia

SpaceX still leads the rest of the world in successful launches, 76 to 57.

NASA delays Axiom manned mission again

Without providing any specific details, NASA today announced that it has once again scrubbed the June 22, 2025 launch of Axiom’s Ax-4 manned mission to ISS as it assesses the Russian repairs to the air leaks in the Russian Zvezda module.

The space agency needs additional time to continue evaluating International Space Station operations after recent repair work in the aft (back) most segment of the orbital laboratory’s Zvezda service module. Because of the space station’s interconnected and interdependent systems, NASA wants to ensure the station is ready for additional crew members, and the agency is taking the time necessary to review data.

No new launch date has been set. Because the agency provides so little specific information, we don’t know if the air leak repairs are working, are failing, or have indicated even more serious problems that make any station docking a greater risk. Almost certainly, this latter fear is unfounded and the repairs have succeeded in stopping or slowing the loss of air, but the paucity of information from NASA allows for wild speculations. It would be better if the agency told us what it has so far learned, and exactly why that knowledge requires it to extend the data-gathering time period.

June 19, 2025 Quick space links

Courtesy of BtB’s stringer Jay. This post is also an open thread. I welcome my readers to post any comments or additional links relating to any space issues, even if unrelated to the links below.

This is also late today because my IP, Centurylink, went down in the Tucson area for about three hours. As is usual for this crap company, their customer service line was down also, stupidly telling me to go to their webpage to get service, even though I was calling because I had no service. Idiots.

Sublimating ice in the Martian dry tropics?

Sublimated ice in the Martian dry tropics?
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on May 3, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled merely as a “terrain sample,” it was likely snapped not as part of any specific research project but to fill a gap in the camera’s schedule so as to maintain the camera’s proper temperature.

When the MRO camera team does this, they try to pick features of interest at the time required, and I think succeed more often than not. In this case, they captured this one-mile-wide unnamed crater that appears to be filled with sublimating glacial debris. Similarly, the plateau surrounding the crater seems to also show signs that some sublimation is occurring of ice just below the surface, producing the areas that appear filled with pockmarks.

The location however suggests that if near surface ice here is sublimating away, it hints at a find of some significance.

Why should anyone listen to people who behave like infantile toddlers?

A modern Democrat protester
The modern face of the Democratic Party.
Click for video.

For decades the Democratic Party and the left (I repeat myself) have used public demonstrations to garner support for their agenda. A bunch of protesters would gather in some public place, holding preprinted signs and demanding “action” for some leftist cause or another. The propaganda press would then give the protest loving coverage, advocating the cause nationwide as something that “must be done.”

For decades these protests have had some success. They forced the public debate to move in the direction the protesters wanted, and almost routinely resulted in legislative or executive actions that they supported.

All this has changed. The recent protests against the Trump administration’s effort to deport illegal immigrants, often devolving into violence, rioting, and looting, have done nothing to shift Trump’s policies. More important, they have done nothing to convince the public to their cause. If anything, all polls indicate these protests have been counter-productive, that the public has shifted even more strongly in its support of Trump.

The picture to the right, a screen capture from the video below, I think illustrates beautifully why these protests have failed so spectacularly. It shows a woman insanely trying to stop an ICE vehicle carrying captured illegals by grabbing the bus’ front grill. As she does this she starts screams madly, first by shrieking “Let my people go!” and then “Don’t kill me!” as the vehicle begins to accelerate. Eventually ICE officers pull her away, but then she tries to grab the side of this bus as well as two others that follow, all the while continuing her mindless screeching.

Ground-based imagery now suggests China has completed a docking and undocking of two robotic servicing satellites

According to ground-based imagery by the commercial company S2A, China’s Shijian-21 and Shijian-25 robotic servicing satellites appear to have completed a docking and undocking on June 13 and June 14, 2025.

China’s Shijian-21 and Shijian-25 satellites had been moving toward each other in geosynchronous orbit, around 22,236 miles (35,786 kilometers) above the equator, Spacenews reported on June 6. And now the pair appear to have had a brief first encounter, according to observations from the ground.

Optical tracking by the space situational awareness firm s2a systems shows a close approach between the two on June 14, with the pair, at times, virtually unresolvable from the other. This suggests that Shijian-21 and Shijian-25 made at least a test-run close approach and may have even performed a docking and undocking test.

You can see video of the first apparent docking here.

Shijian-21 was launched in 2021, and was used to grab a defunct Chinese geosynchronous satellite and tug it to a graveyard orbit. Shijian-25 was launched in January 2025 to test robotic servicing of satellites. These maneuvers with Shijian-21 appear to be part of those tests.

Monaco-based startup unveils its proposed European-built lunar rover

Capitalism in space: The Monaco-based startup Venturi Space, this week unveiled its own proposed European-built lunar rover, dubbed Mona Luna. and offered it to both the European Space Agency (ESA) and France’s CNES space agency.

Venturi has received some support from ESA for key technologies needed for the rover. The company is hoping to win support for a rover development project at ESA’s ministerial conference in late November, when member states will decide on funding for agency programs for the next three years. Antonio Delfino, Venturi’s director of space affairs] argued a rover like Mona Luna fit a gap in Europe’s exploration plans. Mona Lisa is designed to be delivered to the lunar surface on ESA’s Argonaut lander, which would launch on an Ariane 64.

The company has said it is willing to commit some of its own investment capital to develop the rover, should either ESA or CNES decide to buy it. Whether ESA or CNES agree to build this rover however will likely depend on whether either has a program to land on the Moon. At the moment the status of NASA’s Artemis program is unclear, and it was that program that Europe was relying on to get to the Moon.
