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.

Starlink begins or expands service in three more countries

Starlink this week officially began service in both India and the African country of Guinea-Bissau, while expanding its service in the Ukraine to include phone-to-satellite texting.

In India the final licensing approval came through, and the service is now available to customers through two different Indian telecommunication platforms.

The deals consists of selling Starlink’s equipment through Jio and Airtel’s retail networks, while Jio will also offer customer service, installation, and activation support. It will emphasise on providing high-speed internet to businesses, healthcare centres, schools and remote communities across India, according to reports.

SpaceX also begain to offer its services in Guinea-Bissau, a former Portuguese colony located on Africa’s northwestern coast and the seventh African country to approve Starlink. Its license had been approved in April, but the service wasn’t available apparently until now.

Finally, regulators in the Ukraine have now approved the use of Starlink’s phone-to-satellite service by the Ukrainian telecommunications company Kyivstar. The program will at present be limited to texting and emergency alerts. This expands Starlink’s already extensive internet availability there.

In every case, Starlink will act to decentralize control of communications aware from the government, as its sells terminals to ordinary citizens.

Russia launches classified military satellite using its Angara-5 rocket

Russia today successfully launched a classified military satellite, its Angara-5 rocket rocket lifting off from its Plesetsk spaceport in northeastern Russia.

This was the fifth flight of the Angara-5 rocket, the most powerful version in the Angara family of rockets that Russia first proposed three decades ago to replace its older rockets and has had an extremely slow development history. Its core stage and four strap-on boosters crashed in drop-zones across Russia,

On June 9, 2025, the administration of the Kolpashevo District in the Tomsk Region of Russia declared several communities at risk of debris impact during an Angara-5 launch scheduled around 06:00 Moscow Time on June 19, 2025. The danger area covered the Verkneketsky, Kolpashevsky, Kargasoksky and Parabelsky Districts and was located around 65 kilometers north-west of Lake Tresh. This particular area, located around 2,320 kilometers downrange from Plesetsk, would normally be used as a drop zone for the second stage of an Angara rocket heading to an orbit with an inclination 63.4 degrees toward the Equator.

The rocket’s first stage boosters were expected to fall in the Komi Republic around 850 kilometers downrange, while the third stage would splash down in the Pacific Ocean, east of the Philippines, where the Russian authorities also declared a danger zone.

The leaders in the 2025 launch race:

76 SpaceX
34 China
8 Rocket Lab
7 Russia

SpaceX still leads the rest of the world in successful launches, 76 to 56.

Major explosion during preparations for static fire test of Starship prototype

The moment the explosion begins on this Starship prototype<

As engineers tonight were preparing for a standard static fire engine test at Boca Chica of the next Starship prototype, expected to fly on the tenth Starship/Superheavy test flight, the spacecraft suddenly exploded.

I have embedded video of the explosion below. The event occurred prior to the actual static fire test, while Starship’s tanks were being filled. The image to the right is a screen capture just as the explosion begins. The white cloud is the initial release from the explosion (not standard venting), with the red dot indicating the location where the event began. It appears very much to have started inside this Starship spacecraft, which SpaceX was preparing for the next test flight.

Fortunately, no injuries have been reported.

Obviously, this is going to delay somewhat that tenth test flight. SpaceX has more Starship prototypes ready to go, but the company must first figure out what went wrong in this case. It also appears there might be some damage to that test stand, which will also have to be rebuilt so that future static fire tests of upcoming Starships can take place.

France’s space agency agrees to let Spanish rocket startup PLD establish its own launch site at French Guiana

Though France’s space agency CNES had initially attempted to place many rules and restrictions on the commercial operations of new independent private rocket companies at its spaceport in French Guiana, it has now backed off those demands in agreeing to let the Spanish rocket startup PLD establish its own launch site there at the decommissioned launchpad used by France’s Diament rocket in the 1970s.

This new contract greenlights the implementation of the infrastructure project designed by PLD Space with technical support from CNES and grants legal use of land in the ELM-Diamant area, where the MIURA 5 Preparation Zone and Launch Zone will be located. Construction will begin with the start of the dry season in French Guiana, expected in the summer months of 2025.

In September 2024 CNES said it wished to standardize the launch site for the seven different European rocket startups (Avio, HyImpulse, Isar Aerospace, MaiaSpace, PLD Space, Rocket Factory Augsburg, and Latitude) it had approved to use it. At the time I sensed there was opposition from these companies to this policy, since each rocket was different and would not function with this standardized design.

At a minimum that policy apparently delayed PLD’s plans, as it originally hoped to start its launchpad construction in October 2024 and launch in 2025. That schedule went by the wayside.

It now appears PLD will proceed with development as it wishes, for its rocket, and the others will have to figure out how fit their rockets to that design. Or maybe CNES is going to open up further sites at French Guiana to avoid this conflict.
