Exposed weirdness on floor of Martian crater

12:18 pm

Crazy shapes on floor of Martian crater
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on November 27, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this “exposed crater floor materials”. While properly vague, that hardly suffices. This image could easily fall into my “What the heck?!” category of Martian geology that is difficult to understand, no less explain.

The color strip suggests that dust dominates near the top and bottom, though dust is also present in the middle. The patches with the bluish tint in the middle suggests these lighter swirls and patches are bedrock.

Of course, none of that explains the weird shapes of these patches, nor why they exist at all.

Before delving into those weird shapes, we must note the two vertical black strips to the right of the color strip, indicating a gap in data. Such gaps have been appearing more frequently of late, suggesting MRO’s age, almost a decade in orbit around Mars, is beginning to show itself. A failure in 2023 in one filter band of the high resolution camera already leaves blank the color swath in black and white images. These new blank strips indicate further issues, warning us that we must be prepared for the loss of this camera and orbiter in the somewhat near future.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

China claims it has launched and landed a new suborbital reusable spacecraft

10:05 am

Reports from China’s state-run press today and yesterday claim that a pseudo-company, CAS Space (wholly owned by a government agency) has successfully completed the first test flight and parachute recovery of a new small scale suborbital reusable spacecraft dubbed PH-1.

The vehicle lifted off at about 4 pm and reached an altitude of roughly 120 kilometers, passing the Karman line — commonly regarded as the boundary between Earth’s atmosphere and outer space — before descending back to Earth. After re-entering the atmosphere, its recoverable payload cabin deployed a parachute at around 10 km and landed smoothly at a designated site, the company said.

CAS Space said the test validated key technologies, including re-entry deceleration, parachute recovery and precision landing control. Engineers also assessed the performance of critical components during the flight.

A handful of images were released yesterday, but none showed the recovered capsule or its landing.

It is probably that this test was as successful as China’s press claims. It is also possible that this reporting has been carefully designed to hide aspects of the flight that were a failure.

Once developed, CAS Space claims the spacecraft, also dubbed Lihong-1, could be used to provide experiments about 300 seconds of weightlessness. This is not much longer than the periods of weightlessness produced when flying in a “vomit comet” airplane. Moreover, this spacecraft appears too small for manned flights. A larger spacecraft would have to be developed for that purpose.

No alien civilizations? After analyzing two decades of data SETI@Home produces 100 signals “worth a second look”

9:08 am

For more than two decades, from 1999 to 2020, the Search for Extraterrestrial Intelligence (SETI) project asked millions of people worldwide to loan it the use of their computers so the project to could analyze twelve billion signal detections that were of interest.

After 10 years of work, the SETI@home team has now finished analyzing those detections, winnowing them down to about a million “candidate” signals and then to 100 that are worth a second look. They have been pointing China’s Five-hundred-meter Aperture Spherical Telescope, a radio telescope referred to as FAST, at these targets since July, hoping to see the signals again.

Though the FAST data are not yet analyzed, [computer scientist and project co-founder David Anderson] admits he doesn’t expect to find a signal from ET.

At the link the SETI team outlined the many reasons, all quite reasonable, for the failure to detect any obvious signals from alien civilizations. The universe is vast, they only looked at a very tiny slice, the variations of signals are many, and the amount of data was still so gigantic analyzing it was endlessly time-consuming. Moreover, they might have been looking at the wrong wavelengths, and there is even the possibility that advanced civilizations simply don’t broadcast at any wavelengths.

Nonetheless, the project was not a failure. It showed it was possible to use a lot of home computers to create the equivalent of a super-computer. The technology and volunteer system it developed has since been used by other scientists on projects like looking for clouds on Mars and studying galaxy types.

The big question remains unanswered however. Considering the numbers of stars in the galaxy, and the recent data that shows most have planets, it seems strange that there have been so few candidate detections, and even these are questionable. Could it actually be the case that we are the first sentient intelligence species in the Milky Way?

There always has to be a first. That humanity might be that first is a mind-blowing thought.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Mitsubishi buys space on proposed Starlab space station

The Japanese company Mitsubishi has now signed an agreement with the consortium building the large single module Starlab space station that will launch on Starship, reserving part of that station for the company’s own use while also increasing its financial investment in the project.

Starlab Space LLC today announced that Mitsubishi Corporation has reserved and pre-purchased capacity on Starlab’s commercial space station, becoming a foundational customer while simultaneously increasing their investment in the company and joining Starlab’s Board of Directors through representative Issei Shinohara.

The expanded partnership includes acquisition of usage rights for designated payload volume and utilization of on orbit laboratory facilities on Starlab, positioning Mitsubishi to accelerate space-based research opportunities for Japanese institutions. This customer commitment is accompanied by an expanded equity partnership that brings additional investment to support Starlab’s development.

Mitsubishi had in April 2024 already joined the Starlab partnership, though almost no details were announced at that time. Today’s announcement provides those details. It also appears Mitsubishi is bypassing Japan’s space agency JAXA, which in the past always ran such international projects. Instead Mitsubishi will directly “support Japanese space development objectives while contributing to advancements in areas such as life sciences research, advanced materials development, and next-generation manufacturing technologies.” In other words, it is telling JAXA to jump in the lake. It can do this better without that government third party, which by the way has not been very effective in recent years.

This deal continues Starlab’s aggressive momentum in recent months. Though Axiom is still listed above it in my rankings below of all the American space stations under development, I now consider the two essentially tied for second.

Portugal signs Artemis Accords

8:30 am

Portugal yesterday become the 60th nation to sign the Artemis Accords, according to an announcement posted by NASA administrator Isaacman on X.

In October 2025 a Latvia government report had indicated that it had signed the accords, making it the 60th nation in this American alliance, but Isaacman’s announcement did not include it.

Thus, Portugal is the 60th nation, with this the full and corrected list: Angola, Argentina, Armenia, Australia, Austria, Bahrain, Bangladesh, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Israel, Italy, Japan, Liechtenstein, Lithuania, Luxembourg, Malaysia, Mexico, the Netherlands, New Zealand, Nigeria, Norway, Panama, Peru, Poland, Portugal, Romania, Rwanda, Saudi Arabia, Senegal, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the Philippines, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

I suspect Latvia will soon make it official, especially because its neighbors, Estonia and Lithuania, have already signed. These three former Soviet vassal states try to work together as this reduces the Russian threat.

Portugal’s signing means practically all of Europe is now on board.

Isaacman makes it official: Artemis-2 will fly manned around the Moon, despite Orion’s heat shield concerns

8:01 am

Orion's damage heat shield
Damage to Orion heat shield caused during re-entry in 2022,
including “cavities resulting from the loss of large chunks”

In a tweet yesterday afternoon, NASA administration Isaacman essentially endorsed the decision of the NASA managers and engineers in its Artemis program who decided they could live with the engineering issues of Orion’s heat shield (as shown in the image to the right) and fly the upcoming Artemis-2 mission around the Moon carrying four astronauts with that same heat shield design.

Isaacman’s statement however suggests to me that he is not looking at this issue as closely as he should.

Human spaceflight will always involve uncertainty. NASA’s standard engineering process is to identify it early, bound the risk through rigorous analysis and testing, and apply operational mitigations that preserve margin and protect the crew. That process works best when concerns are raised early and debated transparently.

I appreciate the willingness of participants to engage on this subject, including former NASA astronaut Danny Olivas, whose perspective reflects how serious technical questions can be addressed through data, analysis, testing, and decisions grounded in the best engineering judgment available.

SpaceX launches another 29 Starlink satellites

2:49 pm

SpaceX today completed its fifth launch in 2026, placing 29 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage competed its 25th flight, landing on a drone ship in the Atlantic.

At this moment the entire 2026 launch race is SpaceX, and SpaceX only. The only other entity to attempt a launch so far in 2026 has been India’s space agency ISRO, and that launch was a failure last night.

New research supports theorized intermittent ocean exiting Mars’ giant Valles Marineris canyon

11:31 am

Theorized ocean from 2019 & 2022 papers
Theorized ocean from 2019 & 2022 papers

Scientists studying the deltas of debris that exist at the base of the cliffs inside Mars’ giant Valles Marineris canyon have concluded the deltas suggest the existence of an ocean there about three billion years ago.

The theorized ocean on the map to the right comes from research published in 2019, with additional support published in 2022. This new work supports those conclusions. From the press release:

At the lower end of the canyon system, so-called “scarp-fronted deposits” were discovered, which are interpreted as “fan deltas”. Fan deltas form where a fan-shaped cone of debris and sand grows directly into a standing body of water. The researchers found that the structures mapped on Mars are very similar to classic deltas on Earth.

…The results also show that the ocean found was at least as large as the Arctic Ocean on Earth. Schlunegger says: “We are not the first to postulate the existence and size of the ocean. However, earlier claims were based on less precise data and partly on indirect arguments. Our reconstruction of the sea level, on the other hand, is based on clear evidence for such a coastline, as we were able to use high-resolution images.”

You can read the new paper here [pdf]., which I strongly suggest as the press release at the link above is very poorly written. The 2019 and 2022 work focused on computer models and the geological features in the region of the theorized ocean, including evidence of possible past tsumanis. This new research focuses on the debris piles at the base of Valles Marineris’ cliffs, all of which appear to end at similar elevations. As this new paper notes:

Comparing the global ground stations of China and the U.S.

10:49 am

Link here. The article is an excellent review of China’s ground stations located globally, noting how its network is far more limited that the United States, caused by a lack of trust of its intentions by foreign countries.

China currently has access to at least 18 overseas space facilities in Africa, Antarctica, Latin America, South Asia, and the South Pacific. There is no evidence to suggest that any of these countries might expel China’s space tracking and surveillance stations anytime soon. But the longevity of these sites is more precarious than those of the United States. Changing political conditions and concern that these sites may play a role in a conflict involving the United States could undermine China’s ability to maintain key parts of its overseas space tracking network.

The article then notes how China has recently lost stations in Australia, New Zealand, and the Czech Republic and has been forced to field a fleet of ocean-going satellite-tracking ships, similar to what the Soviet Union did during the Cold War.

China proposes building two new satellite constellations, each with about 100,000 satellites

9:46 am

China has filed papers with the International Telecommunication Union (ITU) — the international licensing agency comparable to the U.S.’s FCC — to build two new satellite constellations, each with about 100,000 satellites that would be linked as one gigantic constellation.

The filings, submitted to the ITU in late December 2025, are designated CTC-1 (CHN2025-79441) and CTC-2 (CHN2025-79398), each covering 96,714 satellites in 3,660 orbital planes, according to documents posted in the Union’s “as-received” database.

CTC-1 includes both advance publication information (API) and a more detailed coordination request, reflecting progression through different stages of the ITU regulatory process for a single notional Non-Geostationary Orbit (NGSO) system, while CTC-2 currently remains at the API-only stage. Both reference a “new operating agency” as a placeholder for their operating agencies.

Together, the pair represent one of the largest constellation filings ever made, highlighting the growing competition over orbital and spectrum resources.

Both filings appear to be very preliminary, and in fact appear to be an attempt by China to grab control of as much orbital territory and satellite spectrum as possible, to block others from access. Neither has been approved, and won’t be without a detailed review by the ITU.

Space station Starlab gets major new investor

9:25 am

Starlab design in 2025

for original image.

The consortium led by Voyager Technologies that is building the Starlab space station announced last week that it has obtained a major new investor with more than a billion dollars in assets.

The investor, Seven Grand Managers, is based in New York. The announcement did not specify how much the firm had committed to the Starlab project, but it was clear from this statement that involved significant funds.

“Starlab is being built to be commercially viable from Day One,” said Chris Fahy, founder and chief investment officer, Seven Grand. “Our investment recognizes that commercial infrastructure in the post-ISS era is not speculative, but tangible, bankable and poised for growth. Starlab’s world-class management team and strategic partners are unlocking the beginning of this enormous opportunity.” [emphasis ine]

The highlighted quote suggest Seven Grand was impressed with the Starlab concept, a single very large ready-to-go station launched on Starship. Most of the other stations will involve assembly of multiple modules on multiple launches before they are “ready-to-go.” The only other station launching as a single module, Max Space’s Thunderbird, has only recently entered the race, and is thus far behind.

Starlab had previously raised $383 million in a public stock offering, in addition to the $217.5 million provided by NASA. This new private investment capital further strengthens its future, and suggests the station could get built and launched, even if it fails to win a major station construction contract from NASA.

Below are my rankings of the five American space station projects:

India’s PSLV rocket experiences the second launch failure in a row

11:43 pm

India’s space agency ISRO tonight attempted its first launch in 2026 and the first launch of its PSLV rocket since the rocket’s third stage failed during a May 2025 launch.

Unfortunately the rocket’s third stage failed again, near the end of its engine burn. The animation on the mission control displays, based on actual telemetry, showed the stage suddenly tumbling, its engines no longer firing. It appears something catastrophic occurred the end of that burn.

The rocket’s primary payload (a satellite for India’s military) as well as 18 smallsats for a variety of other customers were all lost.

While ISRO last year was able to complete five successful launches of its larger GSLV and LVM rockets, the PSLV was grounded due to that May 2025 failure. Today’s launch was intended to show the third stage problem had been fixed. Instead, it showed that the modifications hadn’t fixed the problem. In fact. it occurred at almost the same time as in the May launch. The link above is cued to just before the stage began tumbling. In May the failure took place 374 seconds into the flight. Today it occurred at 377 seconds into the flight.

Former astronaut once again blasts NASA decision to fly Artemis-2 manned

10:13 am

Charles Camarda on the shuttle
Charles Camarda on the first shuttle flight
after the Columbia failure.

The opposition to NASA’s decision to fly humans in the Orion capsule around the Moon with a questionable heat shield continues. Charles Camarda, an engineer and former NASA astronaut who has repeatedly expressed concerns about that heat shield and had been invited to attend the review meeting that NASA administrator Isaacman had arranged to ease his concerns, has now revealed his concerns were not eased in the slightest by that meeting, and that the Ars Technica article by Eric Berger that suggested otherwise was wrong, and that he is still “outraged” at NASA’s bad engineering decisions.

The rage you witnessed was my observing the exact behaviors used to construct risk and flight rationale which caused both Challenger and Columbia Accidents. Using “tools” inappropriately and then claiming results to be “Conservative.” Not to mention the reliance on Monte Carlo simulations to predict failure probabilities which were also proven to be inaccurate by orders of magnitude in my book “Mission Out of Control” which you claim to have read.

I suggest, in the spirit of transparency, you should ask NASA to release just the “Findings” of NESC Report TI-23-01849 Volume I. Finding 1 states the analysis cannot accurately predict crack initiation and propagation at flight conditions. And there was so much more which was conveniently not presented.

In other words, he finds NASA’s engineering claims that Orion’s heat shield will work using a different less stressful return trajectory as it dives back into the atmosphere about 25,000 mph to be false and untrustworthy. Worse, he sees it as proof that this is a continuation of the same culture at NASA that resulted in the Columbia failure.

Some of the exact same people responsible for failing to understand the shortcomings of the Crater Analysis tool (used tiny pieces of foam impacts to Shuttle tiles to predict a strike from a piece of foam which was 6000 larger and which caused the Columbia Accident) were on the Artemis Tiger Team now claiming they could predict the outcome of the Orion heatshield using a tool (similar to CRATER) called the Crack Identification Tool (CIT) which was also not physics based and relied on predictions of the key paramenter, permeability, which they claim to be the “root” cause, pressure, to vary by three orders of magnitude (that’s over 1000x).

In defense of NASA, those engineers had also presented data that showed Orion’s hull was strong enough to survive re-entry, even if the heat shield failed entirely. It is unclear if Camarda’s objections here apply to that data as well.

Regardless, his strong public disagreement with NASA on this once again raises serious questions about the upcoming manned Artemis-2 mission, set to launch sometime in the February to March time frame.

SpaceX launches NASA’s Pandora exoplanet space telescope

9:32 am

SpaceX today successfully launched a new NASA space telescope, Pandora, its Falcon 9 rocket lifting off from Vandenberg in California.

Pandora is a smallsat focused on studying 20 stars known to have transiting exoplanets. It will look at each repeatedly to draw as much information about the star and the exoplanet as possible. Also deployed were two other NASA smaller astronomy cubesats.

The Falcon 9 first stage completed its 5th flight, landing back at Vandenberg. The two fairing halves completed their first and seventh flights respectively.

At this moment, SpaceX is the only entity to have launched in 2026. This was its fourth launch.

Space Force awards nine launch contracts to SpaceX

1:03 pm

In announcing its next round of satellite launch awards, the Space Force’s Space Systems Command (SSC) has awarded all nine launches (valued at $739 millon total) to SpaceX, bypassing both Blue Origin and ULA.

SSC awarded the [three] SDA-2 missions to SpaceX for launches projected to begin in [the fourth quarter of fiscal year ’26], and awarded the [two] SDA-3 missions to SpaceX for launches to begin in [the third quarter of fiscal year ’27]. SSC also awarded the [four] NTO-5 launches to SpaceX projected to occur in [the first quarter of fiscal year ’27 and the second quarter of fiscal year ’28]. The total value of these awards is $739M.

It is surprising that SpaceX got all nine contracts. Even though SpaceX charges less than ULA, and Blue Origin’s New Glenn rocket is not yet certified by the Pentagon for operational launches, it has been military policy in recent years to distribute this work to more than one launch provider so as to guarantee a redundancy. ULA exists today for expressly that reason. In the past it would have certainly gotten at least one of these launches.

As for Blue Origin, the Space Force could have awarded it at least one of the later launches in ’27 and ’28, contingent on getting New Glenn certified.

That the Space Force bypassed both companies entirely speaks volumes. It appears it has decided to simply go with the best product now available, and to heck with redundancy.

French rocket startup MaiaSpace announces its launch schedule

12:36 pm

The French rocket startup MaiaSpace is now planning to launch a suborbital test rocket in 2026 to be followed by its first orbital flight in 2027.

As the company works toward the commencement of commercial operations in 2027, it is planning to launch an initial suborbital demonstration flight in late 2026 to validate key elements of the Maia launch system. The rocket will be launched in its full two-stage configuration and will carry a reduced propellant load, with MaiaSpace aiming for a minimum altitude of 100 kilometres. … “For what concerns our first flight, we will deploy a minimum viable product designed to test critical phases (lift-off, stages separation, engine ignition of the second stage, …) and to validate the key features required for our first orbital flight.”

Maiaspace is a wholly owned subsidiary of ArianeGroup, the Airbus-Safran partnership that builds the Ariane-6 rocket for Arianespace. Its goal with Maiaspace is to quickly develop a small reusable rocket that can compete with the other new European startups in Germany (Isar and Rocket Factory Augsburg) and Spain (PLD).

FCC approves SpaceX request to expand Starlink by 7,500 satellites

12:21 pm

The Federal Communications Commission (FCC) yesterday approved SpaceX’s request to both expand its Starlink constellation by 7,500 satellites as well as use additional bands of spectrum.

The Federal Communications Commission on Friday approved SpaceX’s request to launch an additional 7,500 of its Starlink Gen2 satellites, bringing the total allowed Gen2 constellation to 15,000. The agency also granted the company’s request to operate in additional spectrum bands and to operate at higher power in other bands between 10.7-30 GigaHertz (GHz), pending the completion of an existing FCC rulemaking where the question is being considered.

…The order also allows SpaceX satellites to use lower orbits, down to 340 kilometers, and provide direct-to-cell service. The company is seeking approval for a separate 15,000-satellite constellation that would provide upgraded direct-to-cell service using spectrum it’s purchasing from EchoStar.

The article notes that under the Trump administration has also revamped the FCC’s grant program, that under Biden canceled an $886 million grant, claiming absurdly that Starlink did not provide service to rural areas. Under the new program “SpaceX is set to serve the most locations of any ISP under the $42.45 billion Broadband Equity, Access, and Deployment program after new Trump administration rules that made it easier for satellite providers to compete for funding.”

Not that SpaceX or any of the other constellations need this government grant. Trump would serve the country better to shut the program down.

An outline of NASA’s present schedule leading up to the Artemis-2 manned lunar fly-by mission

8:11 am

Link here. The mission will slingshot four astronauts around the Moon and back to Earth. The update includes lots of details about the rollout, the dress rehearsal countdown, the follow-up, and finally the various launch windows and the requirements that determine them.

This paragraph however about those requirements struck me:

The launch day and time must allow SLS to be able to deliver Orion into a high Earth orbit where the crew and ground teams will evaluate the spacecraft’s life support systems before the crew ventures to the Moon.

That life support system will be making its first flight in space, with four humans as the guinea pigs. Though this is another example of NASA putting schedule ahead of safety (the system should have flown at least once unmanned), it does indicate the agency recognizes the risk it is taking, and has added this extra longer orbit to give engineers time to test the system.

There are three launch windows, within which there are only five available launch dates:

January 31 to February 14 (February 6, 7, 8, 10, and 11)
February 28 to March 13 (March 6, 7, 8, 9, 11)
March 27 to April 10 (April 1, 3, 4, 5, 6)

In 2022, once NASA managers chose their first launch window, they were able to get the rocket off on the first attempt. There were no scrubs or aborts, though prior to that attempt the launch date was delayed numerous time over five years. Based on that past history, it is likely the agency will succeed on its first attempt in February, barring weather issues.

ISS crew to return on Wednesday January 14, 2026

10:40 pm

The present four-person expedition 11 crew on ISS, which has one member with an undisclosed sudden health issue that needs addressing on the ground, will undock and return to Earth on January 14, 2025 in SpaceX’s Endeavour capsule.

NASA and SpaceX are targeting no earlier than 5 p.m. EST, Wednesday, Jan. 14, for the undocking of the agency’s SpaceX Crew-11 mission from the International Space Station, pending weather conditions. … NASA astronauts Zena Cardman and Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov will splash down off the coast of California at approximately 3:40 a.m. on Thursday, Jan. 15.

Mission managers continue monitoring conditions in the recovery area, as undocking of the SpaceX Dragon depends on spacecraft readiness, recovery team readiness, weather, sea states, and other factors. NASA and SpaceX will select a specific splashdown time and location closer to the Crew-11 spacecraft undocking.

NASA has released no information about the medical issue that canceled a spacewalk and prompted the early return of this crew. We do not even know the name of the impacted astronaut.

Isaacman okays flying Artemis-2 manned, despite heat shield questions

1:53 pm

According to an article posted today at Ars Technica, after a thorough review NASA administrator Jared Isaacman has decided to allow the Artemis-2 mission — set to launch sometime before April and slingshot around the Moon — to fly manned with four astronauts despite the serious questions that still exist about its heat shield.

The review involved a long meeting at NASA with NASA engineers, several outside but very qualified critics, as well as two reporters (for transparency).

Convened in a ninth-floor conference room at NASA Headquarters known as the Program Review Center, the meeting lasted for more than three hours. Isaacman attended much of it, though he stepped out from time to time to handle an ongoing crisis involving an unwell astronaut on orbit. He was flanked by the agency’s associate administrator, Amit Kshatriya; the agency’s chief of staff, Jackie Jester; and Lori Glaze, the acting associate administrator for NASA’s Exploration Systems Development Mission Directorate. The heat shield experts joined virtually from Houston, along with Orion Program Manager Howard Hu.

Isaacman made it clear at the outset that, after reviewing the data and discussing the matter with NASA engineers, he accepted the agency’s decision to fly Artemis II as planned. The team had his full confidence, and he hoped that by making the same experts available to Camarda and Olivas, it would ease some of their concerns.

My readers know that I have been strongly opposed to flying Artemis-2 manned, an opposition I expressed in an op-ed at PJMedia only yesterday. However, after reading this Ars Technica report, my fears are allayed somewhat by this quote:

The first preliminary research into landing a Mars helicopter in the Starship landing zone

Map of rotorcraft images in Starship landing zone

In early November 2025 I posted a cool image from Mars Reconnaissance Orbiter (MRO) that had the very provocative label “Characterize Possible Rotorcraft Landing Site”. While this was not the first such image taken by scientists using MRO to scout out potential landing zones for future Mars helicopter missions (see here and here), this particular image was one of several taken recently that were all within the candidate landing zone for SpaceX’s Starship spacecraft, focused specifically on the low Erebus mountain chain that sits within this part of Mars’ northern lowland plains.

In the January image download from MRO, I found another such image, taken on December 1, 2025. The map to the right shows that Starship candidate landing zone, with all the images taken for SpaceX indicated. The inset adds all the recent images taken for this “possible rotorcraft” mission, including the December image and the previous four (here, here, here, and here), with orange representing images already obtained and yellow those requested but pending.

I decided I needed to find out more, and tracked down the scientist who had requested the images, Eldar Dobrea of the Planetary Science Institute in Arizona. In response to my email, he explained:

Another spiral galaxy that should not exist discovered in the early universe

Early spiral galaxy
Click for original.

Using the Webb Space Telescope, a graduate student at the University of Pittsburgh has discovered another barred-spiral galaxy that should not exist because it exists only two billion years after the Big Bang,.

The false color Webb image of this new galaxy is to the right, reduced to post here. This is the second such early spiral galaxy discovered, with the previous discovery announced in December 2025.

In essence, Ivanov said, “It’s the highest redshift, spectroscopically confirmed, unlensed barred spiral galaxy.” He wasn’t necessarily surprised to find a barred spiral galaxy so early in the universe’s evolution. In fact, some simulations suggest bars forming at redshift 5, or about 12.5 billion years ago. But, Ivanov said, “In principle, I think that this is not an epoch in which you expect to find many of these objects. It helps to constrain the timescales of bar formation. And it’s just really interesting.”

I think he is being careful with his words. Based on present theories of galaxy evolution as well as Big Bang cosmology, spiral galaxies like this should not yet exist this early.

Chinese pseudo-company building 3/4 billion dollar rocket factory

9:07 am

Though the Chinese pseudo-company Space Epoch has yet to launch any orbital rockets, it has announced it will spend $740 million on a factory for building its reusable rockets, intended to land on a platform at sea.

The 5.2 billion yuan ($740 million) project, led by Beijing-based space launch company Space Epoch, got underway on January 7. According to Hangzhou Daily, it will produce medium-to-large liquid-fueled rockets capable of reuse, high payloads, low cost and sea recovery. The facility, when ready, will manufacture up to 25 of these rockets a year. “A reusable rocket is like a taxi, satellites are the passengers, and a constellation of satellites is a busload of tourists,” Wei Yi, founder and chairman of Space Epoch, told local newspaper Hangzhou Daily.

The cost of space launch vehicles for mainstream rockets in China is approximately 80,000 to 100,000 yuan per kilogram ($11,000 to $14,000), Wei Yi explains. With Space Epoch’s “stainless steel + liquid oxygen and methane” solution, the cost is expected to be slashed to 20,000 yuan per kilogram, he adds.

The only flight tests that Space Epoch has publicly admitted to was a successful hop of a small scale Grasshopper-type prototype in May 2025. This new construction project suggests it has been able to raise the money to build its full scale rocket. I suspect some if not all of that money came from the Chinese government.
