Soyuz safely returns three astronauts from ISS

A Russian Soyuz capsule successfully landed in Kazakhstan this morning, bring two Russians and one American back to Earth after a seven month mission to ISS.

The American on board, Don Petit, also celebrated his 70th birthday today, completing his fourth mission in space. According to the article at the link, he did not do well upon landing, requiring significant aid to exit the capsule. The picture released by NASA of him being carried to the medical tent shows him smiling with a thumbs up, but he is clearly unable to walk at this point on his own. That fact by itself is not significant, because many astronauts after missions lasting longer than six months need aid upon return. It does indicate however that this flight is almost certainly Petit’s last one. As that NASA release it notes he “is doing well and in the range of what is expected for him following return to Earth.”

China launches six technology test satellites

China today successfully placed a set of six technology test satellites into orbit, its Long March 6 rocket lifting off from its Taiyuan spaceport in northeast China.

No word on where the rocket’s lower stages and four strap-on boosters crashed inside China. Furthermore, the upper stage of the Long March 6 rocket, which reaches orbit, has a history of breaking up and creating clouds of space junk. We have no assurance from China whether they have fixed this issue.

The leaders in the 2025 launch race:

43 SpaceX
20 China
5 Rocket Lab
5 Russia

SpaceX still leads the rest of the world in successful launches, 43 to 35. (Note: this last number is corrected from the previous update, which was one number short.)

Curiosity drill cores suggest there are more carbon-based minerals on Mars than previously believed

The uncertainty of science: Scientists studying four different core samples drilled by the Mars rover Curiosity have detected abundant amounts of the iron carbonate mineral siderite, suggesting that there is more carbon within Mars’ crust than previously believed.

If that quantity of carbon is confirmed, there might also have been a carbon cycle between Mars’s atmosphere and the liquid water theorized to have once been on the surface. This cycle could also have made the atmosphere both thicker and warmer, conditions necessary for that liquid water to exist on the surface. From the research paper:

[D]ecomposition of siderite occurred in multiple locations and released CO2 into the atmosphere, recycling CO2 that was originally sequestered during siderite formation. Diagenetic carbonate destruction observed elsewhere on Mars, in martian meteorites, and in sandstones on Earth yields nearly identical reaction products to those we found in Gale crater and are observed globally in orbital data. We therefore conclude that in situ, orbital, and terrestrial analog evidence all indicate that postdepositional alteration of siderite closed the loop in Marsโ€™ carbon cycle, by returning CO2 to the atmosphere.

The uncertainties here are gigantic. For these conclusions to be right, the scientists extrapolate without evidence the same amount of CO2 found in these four cores as existing across the entire surface of Mars. That is a very big extrapolation that no one should take very seriously.

Furthermore, this research assumes the geological features we see on Mars were formed from liquid water. More recent orbital data suggests glacial and ice processes might have played a part instead, with one study concluding that Gale Crater was never warm enough for long-standing liquid water, and that ice and glacial processes must have played the larger part in forming what we find there.

The data from these core samples however is intriguing for sure, though it mostly raises more questions about Mars’ past geological history than it answers.

Two different states in India announce space policies

Map of India

Capitalism in space: In another indication that India’s governments are going full bore for private enterprise in space, two different Indian states this week announced new space policies designed to attract private investment and space startups.

Those two states, Tamil Nadu and Gujarat, are shown on the map to the right. Tamil Nadu announced its new space industrial policy hopes to attract more than a billion dollars in space companies to the state. Gujaret in turn announced its own space policy aimed at attracting $5 billion in investment and 25,000 jobs over the next five years.

It is not surprising that Tamil Nadu has issued this policy, considering that it is the state where India’s new second spaceport, Kulasekarapattinam, is located, and is being built as a launch site for commerical operations. Gujaret is at first glance less obvious, but it houses a major facility of India’s space agency ISRO. It is also one of India’s most industrialized states.

Both however illustrate the impact of the Modi government because of its policy to encourage private enterprise and de-emphasize government control. Not only is the federal government pushing capitalism, the country’s individual states are joining in.

NASA’s useless safety panel suddenly notices that there are leaks on ISS

My regular readers will know that I consider NASA’s Aerospace Safety Advisory Panel (ASAP) to be less than useless, repeatedly showing strong biases that allow it to miss major safety issues while causing headaches where no safety problems exist. Those biases consistently favor NASA and the older big space companies while attacking the new space companies like SpaceX.

This week the panel held its quarterly public meeting, and illustrated their uselessness and bias once again. Suddenly they have noticed that ISS has a serious chronic air leak problem due to the stress fractures in the Russian Zvezda module. They also came to the brilliant discovery that ISS is big, and that its de-orbit will have to be done carefully.

Oh my! Will wonders never cease!? These facts have only been documented at length and frequently by numerous inspector general reports and NASA updates over the past half decade. NASA has in fact contracted SpaceX to build a specialized de-orbit spacecraft, larger than a Dragon capsule, to dock with the station and conduct the de-orbit.

NASA didn’t need this safety panel to tell it the obvious.

Meanwhile, the panel suddenly decided it must chime in on budget issues and the possibility of there being major cuts at NASA, something that is entirely outside its area of responsibility. And to no one’s surprise it announced that budget cuts are bad!

Nor did the panelists see any safety issues with putting astronauts in an Orion capsule and flying them around the Moon on the next Artemis launch, even though NASA and its inspector general have both determined that the capsule’s heat shield is unreliable. The panel also had no problem with flying humans in this capsule the very first time its environmental system is tested.

To these political hacks, they see “we see no showstoppers at this time” for this SLS/Orion manned mission.

Instead, as always, the panel focused its criticism and concerns on SpaceX and Starship, labeling its development “the biggest risk” in NASA’s program to get Americans back to the Moon.

The most hilarious aspect of the panelists’ public comments is that they had nothing to say about Boeing’s Starliner, a pattern the panel has followed since Boeing and SpaceX got contracts a decade ago to transport astronauts to and from ISS. Consistently the panel has seen phantom safety risks with SpaceX — where none existed — while ignoring or completely missing Boeing myriad failures. That pattern continues.

NASA does face budget cuts. It would certainly help the agency if every dime wasted on this panel could be funneled into more useful purposes.

An American government program to get to the Moon is simply not necessary; If we let them Americans will do it on their own

As a historian I often bring to any discussion of modern politics and our American space effort a perspective that is very alien to modern Americans. I see things as they once were in the United States back before we had a big overbearing federal government that everyone looked to for leadership. Instead, I see the possibilities inherent in a free nation led by the people themselves, not the government, as America was for its first two centuries.

This sadly is not how America functions today, and it is for that reason that as a nation we can no longer get great things accomplished routinely, as we once did.

Norwegian Amundsen, first to reach the south pole
Norwegian Amundsen, first to reach the south pole.

To understand how different the American mindset once was, consider just one example, the 19th century effort by numerous nations and individuals to plant their flag at both the north and south poles. While a handful of private American citizens mounted their own expeditions to reach the north pole, none attempted to do so in Antarctica. At both poles the bulk of the effort was done by other nations, sometimes on expeditions privately funded, and sometimes by expeditions with extensive government aid.

In the U.S. however there was no government program to compete in this race. Nor was their the slightest desire by Americans to create one. The attitude of Americans then was very straightforward. They found the race to get to the poles exciting and fascinating, and thoroughly supported the efforts of the explorers both intellectually and emotionally. They however had no interest in their government committing one dime of their tax dollars on its own campaign.

You see, they did not feel a need to establish American prestige in this manner. So what other nations got to the poles first? What mattered to Americans then was what each American wanted to do, and what Americans wanted to do in the 19th century was to settle the west and build their nation into a prosperous place to raise their children.

And so, the south pole was first reached by a Norwegian, followed mere weeks later by an Englishman. Americans played no major role in that early exploration. Nor did it harm America’s prestige in the slightest that it did not compete there. The nation was growing in wealth and prosperity, its citizens were completely free in all ways to follow their dreams, and everyone worldwide knew it.

America might not be the leader in far-flung exploration, but the world knew it was the leader in something as important if not more so, the idea that a nation and a government could be built on the premise that the citizen is sovereign, and that all law should be based on making that citizen’s life, liberty and the pursuit of happiness primary in all things.

And in the end, it did not really matter that the U.S. did not compete in that race to the poles. » Read more

Oman’s proposed spaceport at Duqm.

Oman yesterday announced that it has added a viewing area so that the public can view the planned half dozen launches that are presently planned for the rest of 2025 at its new spaceport in Duqm.

A three-day fan experience in the free-of-charge zone, called Etlaq FX, will feature a series of activities for different age groups, including a robotics competition.

โ€œIt is an interactive area within the spaceport, so we can give the public an opportunity to see the launch and engage them with educational activities,โ€ said Zainab Alsalhi, business development manager for Etlaq, during a webinar this month.

The announced launch schedule is of course the real story, as it involves five launches from two different commercial companies as well as from Kuwait.

Japan’s Hayabusa-2 asteroid probe in safe mode

Japan’s Hayabusa-2 asteroid probe, which had successfully dropped off samples from the rubble-pile asteroid Ryugu in 2020 and then was sent on a long journey to visit two more asteroids, has suffered an unknown anomaly and shifted into safe mode to protect its instruments.

Communications between Earth and the spacecraft were stable, however, and teams were investigating the situation and its impact on the extended mission, a machine translation of the post read. JAXA has yet to provide a new update since posting about the anomaly.

If engineers can identify the problem and bring the spacecraft back into full operations, the hope is that it will fly past another asteroid in 2026 on its way to a third in 2031, where it will remain for a period of time doing more detailed observations.

Texas lawmakers now lobbying to move NASA headquarters to Houston

First it was Florida. Then it was Ohio. Now Texas lawmakers are lobbying the Trump administration to move NASA headquarters from Washington to Houston.

A coalition of Texas lawmakers is calling on President Donald Trump to relocate NASA’s headquarters to Houston when the office lease in Washington D.C. expires in 2028. U.S. Senator Ted Cruz and U.S. Rep. Brian Babin (R- Woodville) are leading the charge to make Houston the new landing spot for NASA headquarters. Several other Texas representatives signed onto the letter Wednesday urging Trump to make this shift.

That politicians in three different states are lobbying in this manner tells us it is almost certain that NASA’s headquarters is leaving DC. More important, it tells us that the agency’s entire bureaucracy — including its many scattered centers nationwide — are going to go through a major shake-up, including major reductions and closures. It appears Trump has made the headquarters a plum that these politicians are chasing in order to get them to agree to major cuts elsewhere.

Astronomers detect chemicals on exoplanet that on Earth come from life

The uncertainty of science: Using the Webb Space Telescope, astronomers have detected two different molecules that on Earth are only linked with biology in the atmosphere of an exoplanet orbiting a red dwarf star within its habitable zone.

Earlier observations of K2-18b โ€” which is 8.6 times as massive and 2.6 times as large as Earth, and lies 124 light years away in the constellation of Leo โ€” identified methane and carbon dioxide in its atmosphere. This was the first time that carbon-based molecules were discovered in the atmosphere of an exoplanet in the habitable zone. Those results were consistent with predictions for a โ€˜Hyceanโ€™ planet: a habitable ocean-covered world underneath a hydrogen-rich atmosphere.

However, another, weaker signal hinted at the possibility of something else happening on K2-18b. โ€œWe didnโ€™t know for sure whether the signal we saw last time was due to DMS, but just the hint of it was exciting enough for us to have another look with JWST using a different instrument,โ€ said Professor Nikku Madhusudhan from Cambridgeโ€™s Institute of Astronomy, who led the research.

…The earlier, tentative, inference of DMS was made using JWSTโ€™s NIRISS (Near-Infrared Imager and Slitless Spectrograph) and NIRSpec (Near-Infrared Spectrograph) instruments, which together cover the near-infrared (0.8-5 micron) range of wavelengths. The new, independent observation [of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS] used JWSTโ€™s MIRI (Mid-Infrared Instrument) in the mid-infrared (6-12 micron) range.

This data is not yet proof of biology. For example, the concentrations of these molecules in K2-18b’s atmosphere is thousands of times greater than on Earth. It is just as likely that numerous as yet unknown non-biological chemical processes in this alien environment have produced these chemicals. The scientists however are encouraged because the theories about ocean life on this kind of habitable ocean-covered superearth had predicted this high concentration of these chemicals.

At the same time, they readily admit there are many uncertainties in their data. They have asked for another 16 to 24 hours of observation time on Webb — a very large chunk rarely given out to one research group — to reduce these uncertainties.

Northrop Grumman launches reconnaissance satellite

Northrop Grumman yesterday successfully launched a National Reconnaissance Office surveillance satellite, its Minotaur-4 rocket lifting off from Vandenberg in California.

This was the company’s first launch since 2023. Northrop Grumman’s Antares rocket has been out of commission since the company used up its Ukrainian-built first stages, waiting for Firefly to complete its replacement. The repurposed Minotaur-4 missile does not have the capability to replace it.

The leader board for the 2025 launch race remains unchanged:

43 SpaceX
19 China
5 Rocket Lab
5 Russia

SpaceX still leads the rest of the world in successful launches, 43 to 33.
