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.
- On this day in 1976 Viking-1 arrived in Mars orbit
The orbiter would release the lander a month later, soft landing on July 20, 1976 (the anniversary of the Apollo 11 lunar landing).

Sublimating 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?
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
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.

- ESA, Blue Origin, and Thales Alenia sign agreement to vaguely work together in low Earth orbit
It appears the deal will increase the participation of Thales Alenia and the European Space Agency in the development of Blue Origin’s Orbital Reef space station, including Thales Alenia likely building some of the station’s modules. Where Orbital Reef partner Sierra Space stands in this with its LIFE modules is unclear.
- Chinese pseudo-company Azspace touts the final assembly of its first small cargo capsule
No indication of a launch date.
- Varda touts completion of its fourth Winnebago orbital capsule, this time built entirely in-house
It will launch this week on a Falcon 9. The company has also obtained a five year FAA license to bring all its capsules back at the Koonibba Test Range in southern Australia.
- On this day in 1983 Sally Ride became the first American woman to fly in space
During her space shuttle mission the crew deployed two satellites.
- On this day in 2009 Lunar Reconnaissance Orbiter was launched
It has been in lunar orbit ever since, is still operating, and has produced very high resolution maps of the entire Moon.

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.

A blacklisted American wins in court
Bruce Gilley, formerly of Portland State University
Back in 2017 political science professor Bruce Gilley wrote a quite reasonable historical paper in the academic journal Third World Quarterly that took a look at the colonialism of the western nations in 1800s and concluded that this colonialism had not been all bad, and in fact had brought “significant social, economic and political gains” to the nations colonized.
For this sin of honest academic analysis (certainly open to debate), the academic community put together a coordinated international campaign to get his paper withdrawn and his reputation ruined. He received death threats, and later in response to these threats and this campaign — including the resignation of fifteen of its board members — the journal withdrew Gilley’s paper. It didn’t do so because of any academic flaws in the work, only because it dared state conclusions that today’s leftist, Marxist, and very bigoted academic community cannot tolerate.
Soon thereafter Gilley found himself blacklisted and censored at his university, Portland State University in Oregon. The communication manager for its Division of Equity and Inclusion, Tova Stabin, blocked him from a college X discussion group because Gilley had had the nerve in one email to quote Thomas Jefferson, noting that “all men are created equal.”

Astronomer claim radio data detects much of the universe’s “missing mass”
The uncertainty of science: Using radio data from 60 fast radio bursts scattered across the sky, astronomers think they have detected the signature of much of the universe’s “missing mass” that has until now been ascribed to some unknown material dubbed dark matter but in fact is mostly ordinary matter that was previously unobserved.
The results show that about 76% of baryonic matter is in the intergalactic medium, 15% is in the halos around galaxies and the rest is inside stars or cold galactic gas.
From the paper’s abstract:
Approximately half of the Universe’s dark matter resides in collapsed halos; significantly less than half of the baryonic matter (protons and neutrons) remains confined to halos. A small fraction of baryons are in stars and the interstellar medium within galaxies. The majority are diffuse (<10−3 cm−3) and ionized (neutral fraction <10−4), located in the intergalactic medium (IGM) and in the halos of galaxy clusters, groups and galaxies.
In other words, the dark matter is simply ordinary matter made up of ionized “diffuse ionized gas” that ” is notoriously difficult to measure.”
One major uncertainty of this result is its dependence on fast radio bursts. The scientists claim the sixty bursts they used came from distances ranging from 12 million to 9 billion light years, but it is unclear how they determined those distances. We do not currently know the source of fast radio bursts, which means we also do not really know exactly where they occur or how distant they are from us. This research however relies on that uncertain knowledge, because it measures the changes to each burst’s radio emissions as it travels through intergalactic space.
Nonetheless, if confirmed this result shouldn’t surprise us. The universe is gigantic and mostly hard to observe. For there to be a gigantic amount of undetected ordinary matter scattered between the galaxies is perfectly reasonable. Inventing something extraordinary — dark matter — is actually a far more unreasonable scientific strategy.

Another company enters the military’s hypersonic test market
UP Aerospace today announced the successful launch of its suborbital small Spyder rocket, designed expressly for hypersonic flight testing.
The maiden flight took place at 7:00 AM MST at Launch Complex 36 [at White Sands Missile Range in New Mexico], marking a new era in hypersonic mission capabilities. The mission reached the threshold of hypersonic speeds similar to the UP Aerospace SpaceLoft rocket missions that have been operational for 20 years.
In the U.S. the military now can do hypersonic flight tests using this small rocket, Stratolaunch’s giant Roc plane and Talon-A flight vehicle, Rocket Lab’s Haste reconfiguration of its Electron rocket, and Varda’s orbital capsules on their return from space. In addition there is at least one other startup, Radian, that hopes to build a space plane for hypersonic testing as well.
I also expect this testing to result in some new technologies for both commercial aircraft as well as rockets.

Europe’s old aerospace industry struggles with the concept of competition
Two stories today from Europe’s aerospace industry suggest that its older big space companies are having real difficulties dealing with the new space landscape of competition and freedom.
First, Arianespace and Avio issued a statement demanding that Europe require that all European launches occur on European rockets.
The statement warned that without “sustained support,” European rocket builders were at risk of losing out to institutionally backed competitors from the US. “Major space powers support their industries through stable and guaranteed institutional markets, enabling long-term investments, innovation, and the preservation of leadership,” explained the statement.
…The pair argue that Europe risks falling behind not due to a lack of technical capability, but because of structural market weaknesses. While Ariane 6 and Vega-C have demonstrated competitiveness and reliability, they caution that this progress is fragile in the absence of guaranteed long-term demand.
While a preference for European launch providers is clearly in the best interest of both Avio and Arianespace, the pair did reserve a slice for new entrants to the market. “Enshrining European preference as an untouchable principle would support not only Ariane and Vega, but also foster the development of emerging projects in the small launcher sector.” [emphasis mine]

NASA/Axiom announce another four-day launch delay for Axiom’s fourth manned mission
NASA and Axiom today announced that they have rescheduled the launch of Axiom’s fourth manned mission to ISS, dubbed Ax-4, to June 22, 2025 in order to give Russian and American engineers more time to assess the leak repairs in the station’s Russian Zvezda module.
The press announcement provided little information, simply stating that:
The change in a targeted launch date provides NASA time to continue evaluating space station operations after recent repair work in the aft (back) most segment of the International Space Station’s Zvezda service module.
It would be nice if the agency would release some actual data. Earlier reports had suggested that the repairs had completely sealed the leaks and that the station was no longer losing air. The vagueness of today’s report suggests that the repairs might not have been as successful as hoped. It could also be engineers simply want more data for a longer period to prove the repairs have worked.
The lack of detailed information causes unnecessary speculation.

Mars will be mystery until we can walk its surface

Today’s cool image illustrates starkly the limitations of orbital imagery. The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on March 30, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows flow features inside a depression that strongly resemble glacial features, with the downhill grade roughly heading south.
Such features are seen in many places on Mars, almost always in the 30 to 60 degree mid-latitude bands in both the northern and southern hemispheres (see here, here, and here for just three examples. For many more simply search this website using “glacier” or “glacial feature” as search terms).
The problem is that this location is not within that 30 to 60 degree latitude band. In fact, at this location no near surface ice should exist at all.

Honda’s grasshopper rocket successfully completes vertical take-off and landing
Honda today successfully completed the first test of its own grasshopper prototype rocket, with the rocket reaching a height of 890 feet before landing vertically 56 seconds after launch.
I have embedded the video of the flight below.
Honda had announced this project back in 2021, but since then had published no updates of note. This flight indicates that project is real and is on going.
In 2021 the company said it was targeting the first orbital flights by 2030. Today’s update says it will be doing suborbital flights in 2029, which suggests the orbital flights will not occur in 2030.

Under Trump FCC shifts from regulating satellite construction and de-orbit to streamlining red tape
According to a Space News article yesterday, the FCC’s regulatory focus since January and the advent of the Trump administration has shifted significantly from its focus during the Biden administration.
The article describes in detail the present focus to streamline regulations and speed license approvals.
One early result of this push is a reduction in the FCC’s licensing backlog. Schwarz said the space bureau has reduced pending applications by 35 percent since January, including those for new space stations and ground infrastructure.
Modernizing regulations for non-geostationary satellite systems is another priority. The FCC is considering revising so-called “power limit” rules aimed at preventing interference between low-orbit constellations and traditional geostationary satellites and earth stations. Schwarz said these reforms could help pave the way for higher-throughput services that rival terrestrial broadband.
This focus appears correctly centered on the FCC’s actual legal statutory authority to regulate the limited bandwidth of the electromagnetic spectrum to avoid conflicts in its use.
Under Biden, the FCC instead focused on expanding its power beyond that statutory authority, claiming it had the right to determine how satellites were built, when they would be de-orbited, and in what manner. None of those activities have anything to do with bandwidth and the FCC’s legal responsibilities.
There was some legislative push back from Congress during the Biden administration, but it was slow and relatively weak. Now that push back has become unnecessary, because the FCC under Trump is back to doing its actual job instead of trying to build empires of regulation.
The agency also appears, for the moment, to have ended its partisan abuse of red tape for political reasons. Under Biden it used its regulatory power against SpaceX in retaliation to Elon Musk’s decision to publicly support Biden’s political opponents. It appears the present effort to speed license approvals for everyone has ended this practice.

Rocket Lab gets a quick launch contract from unnamed customer
Rocket Lab today announced it has been awarded a launch contract from an unnamed “confidential commercial customer” calling for two launches before the end of this year, with the first to occur only four days from today.
Launching from Rocket Lab Launch Complex 1 in New Zealand, the first dedicated mission on Electron – named “Symphony In The Stars” – will take place no earlier than June 20, 2025 to deploy a single spacecraft to a 650km circular Earth orbit. A second dedicated launch on Electron to meet those same mission requirements is scheduled for launch before the end of 2025.
That the customer name is classified suggests these are both military launches, and are designed to demonstrate Rocket Lab’s ability to launch something fast under short notice. The new contract also increases the chances that Rocket Lab will manage two dozen launches in 2025, a pace of twice a month.

SpaceX launches 26 more Starlink satellites
SpaceX last night successfully placed 26 more Starlink satellites in orbit, its Falcon 9 rocket lifting off from Vandenberg in California.
The first stage completed its third flight, landing on a drone ship in the Pacific.
A comparison between this launch of SpaceX’s Starlink with Amazon’s scrubbed ULA launch of 27 Kuiper satellites yesterday is worth noting. This launch of 26 Starlink satellites was utterly routine, and just one of four in just the past week, all of which put 98 satellites into orbit. Thousands of such satellites have been launched since the first launch in 2018.
Amazon’s attempt to launch 27 Kuiper satellites was scrubbed, and would have only been the second launch total, separated by about six weeks. The constellation only has 27 satellites in orbit, and its launches are anything but routine, despite signing launch contracts with four different rocket companies. And yet, Amazon proposed Kuiper at almost the same time SpaceX proposed Starlink, in the mid-2010s.
I will let my readers draw their own conclusions from this comparison.
The leaders in the 2025 launch race:
75 SpaceX
34 China
8 Rocket Lab
6 Russia
SpaceX now leads the rest of the world in successful launches, 75 to 55.

- NASA’s 96-minute long documentary on the building of the Webb Space Telescope
I haven’t watched it and likely won’t, because I can’t imagine NASA telling the real story of the budget overruns, endless delays, and chronic bad management that plagued Webb from day one.

It will be launched on Japan’s new H3 rocket later this year, the first of five HTV-X supply missions to ISS.
- Chinese pseudo-company Interstellar Glory says the first flight of its Hyperbola-3 rocket will occur by the end of 2025
The rocket is essentially attempting to copy what the Falcon 9 does. Whether the company will recover the first stage on the first launch is definitely uncertain.
- ESA releases first images from its solar telescope Proba-3
It uses a separate “occulter” satellite to block the Sun’s light in order to study the Sun’s corona, its atmosphere.
- On this day in 1963, Valentina Tereshkova became the first woman to fly in space
It would almost two decades before a second Russian woman would fly in space.
- Cockpit footage of Iranian ballistic missiles launching towards Israel, taken from a commercial flight over Dubai
Expect fewer and fewer of these launches in the coming days.

Spinlaunch signs deal to build its spin launch facility on island in Alaska
Spinlaunch has now confirmed that it has signed a deal to build its spin launch facility on Adak island in the far western extent of the Alaskan island chain.
The facility will be a scaled up version of its spin launch test facility in New Mexico, shown to the right, that was used for tests back in 2022, hurling payloads 35,000 feet into the sky up by spinning them up.
Since then the company changed its leadership and shifted focus to building a satellite constellation that will at least initially will be launched by conventional rockets. This new agreement, actually signed in October 2024 but kept secret until now, suggests that it has not yet abandoned its spin launch technology.

ULA scrubs 2nd Kuiper constellation launch due to technical issue
ULA today scrubbed its second Atlas-5 launch to place 27 more of Amazon’s Kuiper constellation satellites into orbit due to “an engineering observation of an elevated purge temperature within the booster engine.”
At the moment no new launch date has been scheduled.
So far Amazon has only placed 27 operational Kuiper satellites into orbit, on a single Atlas-5 launch in April. According to its FCC license, it must have 1,600 satellites in orbit by July 2026. Though it has contracts to launch these satellites 46 times on ULA rockets (8 on Atlas-5 and 36 on Vulcan), 27 times on Blue Origin’s New Glenn, 18 times on ArianeGroup’s Ariane-6, and 3 times on SpaceX’s Falcon-9, except for SpaceX all these companies have had problems getting off the ground.
Whether Amazon can meet the FAA licence requirement by next year is becoming increasingly questionable.
