Martian glacier flowing past small peak

Overview map

Martian glacier flowing past small peak
Click for original image.

Cool image time! The picture to the right, rotated, reduced, and sharpened to post here, was taken on November 24, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

As is proper, the science team labels this vaguely as a “flow obstacle in lobate debris apron.” The obstacle is that small peak. The lobate debris apron is the material flowing past, resembling in almost all details what a glacier looks like on Earth. The scientists use vague terms because they don’t want to trap themselves into a conclusion before it is confirmed.

Nonetheless, based on all the data MRO and other Mars orbiters have been gathering for the past decade, we are almost certainly looking at near-surface ice flowing downhill and past that peak.

The white dot in the overview map above marks the location, on the western end of the 2,000-mile-long mid-latitude strip I label “glacier country,” because practically every image from this region shows features such as this.

The arrow in the inset shows the direction of the downhill grade, dropping from 2,000 to 3,000 feet from the surrounding plateau. The peak itself rises about 130 feet above the flow on the uphill side, but 650 feet above on the downhill side. Apparently the flow piled up somewhat as it hit the peak.

That flow however is likely inactive at this time. Though the researchers have repeatedly monitored the many glacial flows they have found on Mars in the decade since MRO arrived in Mars orbit, so far I have heard of no example showing any movement. And that covers about five Martian years.

These images do prove one thing: Mars is not dry. It has plenty of water near the surface, though locked in ice.

Lockheed Martin and General Electric complete tests of a rotating-detonation engine

10:04 am

Lockheed Martin and General Electric announced this week that they have successfully tested a rotating-detonation engine using complimentary technology developed by each company.

GE Aerospace and Lockheed Martin completed a series of engine tests demonstrating the viability of a liquid-fueled rotating detonation ramjet for use in hypersonic missiles, the first initiative between the companies under a broader joint technology development arrangement.

This fuel-efficient rotating detonation ramjet promises to fly missiles faster—including at hypersonic speeds—and farther while decreasing costs compared to other ramjet options. … The rotating detonation ramjet combusts fuel and air through detonation waves instead of the traditional combustion methods used in ramjet engines today. This propulsion system generates high thrust for super- and hypersonic speeds to engage high-value, time-sensitive targets, with a smaller engine size and weight that boosts range.

In October Lockheed Martin’s venture capital division announced it was investing in a startup, Venus Aerospace, that was developing its own rotating detonation engines. One now wonders, based on today’s story, if that investment might have been a purchase of the technology itself.

Either way, the Pentagon’s program to develop hypersonic missile capability has blossomed in the past two years, since it stopped trying to build the technology itself and has instead been hiring private aerospace companies to do the research for it. Ain’t capitalism wonderful?

The European Space Agency and China hold the first joint meeting in almost a decade

9:50 am

ESA logo

The European Space Agency (ESA) this week hosted the leaders of the China National Space Administration (CNSA) in Paris, the first such joint meeting since 2017.

The meeting was co-chaired by ESA Director General Josef Aschbacher and CNSA Administrator Shan Zhongde. Both ESA and CNSA had unique achievements to share and discuss since the last time the heads of agencies met in person.

Both highlighted joint successes in space science, notably the Tianguan (Einstein Probe) launch with ESA hardware, and progress on the joint Smile mission, set to launch this year. Similarly, the two sides addressed the successful Chang’e-6 mission carrying ESA’s NILS instrument, ESA’s first experiment on the lunar surface. In the field of telemetry and tracking, both looked back on their long-term cooperation in supporting science and exploration missions. In discussing their respective space safety and Earth observation related programmes, the importance of cooperation to protect our planet and climate was recognised on both sides.

It was discussed, that building past progress, both sides in their respective institutional contexts would explore potential opportunities for further collaboration in areas such as Earth and space science.

Let me translate: We in Europe have found that our cooperative Soviet-style government-run projects with NASA (ISS, Mars Sample Return, and Lunar Gateway) are going away, and we need to find some other authoritarian nation we can partner with.

You see, the bureaucrats in Europe like their Soviet-style government-run space program, and are actually offended that the U.S. is shifting from that approach to the capitalism model, an independent industry run by private enterprise. Moreover, these bureaucrats at ESA are finding their own political support dwindling within the ESA’s member nations, many of whom are adopting the same private industry approach as the U.S.

Thus, rather than embrace freedom, competition, and capitalism — the principles that once made Europe great — they look to China now to help fund their government projects. How so very governmental of them!

It is likely some space projects will come of this, but if the U.S. remains steadfast in support of freedom and private enterprise, it will flow like a tidal wave over anything ESA and China develop.

China launches classified military satellite in partnership with Algeria

9:30 am

China today successfully placed a classified military remote sensing satellite into orbit, its Long March 2C rocket lifting off from its Jiuquan spaceport in northwest China.

China’s state-run press provided no update on where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China. The story at the link, from China’s military, did provide this information about the satellite:

Developed by China Academy of Space Technology under China Aerospace Science and Technology Corporation (CASC), the satellite will be used for land planning and disaster prevention and mitigation. The launch is part of the Algeria remote sensing satellite system program, a joint project between China Great Wall Industry Corporation, a subsidiary of CASC, and the Algerian Space Agency. Signed in July 2023, the agreement includes two optical remote sensing satellites, ground systems, training, and related support services.

Indian startup raises seed money to build robotic satellite servicing “jetpacks”

9:22 am

An Indian startup, Aule Space, has now raised $2 million in seed money to begin development of a robot servicing spacecraft it intends to call “jetpacks”, designed to attach to satellites and provide them fuel and power.

The seed funding will allow Aule Space to being work on a demonstration mission planned for launch next year to test its docking capabilities. That will involve two satellites, each weighing about 30 kilograms, but Panchal said one option is to instead use an orbital transfer vehicle as the client for the docking demonstration.

The 11-person company, which plans to grow to 20 people by the end of the quarter, is working on ground tests of its rendezvous and docking technology. It has access to facilities used by the Indian space agency ISRO for testing SPADEX, a docking demonstration mission flown a year ago.

This “jetpack” concept is very similar to Northrop Grumman’s Mission Extension Vehicles (MEV), several of which have already flown and extended the life of several satellites.

Aule is exactly the type of Indian satellite startup that India’s rocket startups, Agnikul and Skyroot, are being built to serve. The problem is that all of these startups, both satellite and rocket, are literally all startups. None has flown. India’s private space sector won’t really take off until its private rocket companies get off the ground, as its government space agency, ISRO, has done a very poor job launching its PSLV and SSLV rockets (both designed for smallsats). The PSLV has failed on its last two launches, and the SSLV has been in limbo now for years.

Expedition-11 crew splashdowns safely

9:03 am

SpaceX’s Endeavour capsule has safely splashed down and been recovered off the coast of California, returning the four Expedition-11 astronauts several weeks early from ISS due to an as-yet undisclosed medical issue with one astronaut.

Crew-11 returned home about a month earlier than planned because of a medical concern teams are monitoring with one of the crew members, who remains stable. Due to medical privacy, it is not appropriate for NASA to share more details about the crew member. Prior to return, NASA previously coordinated for all four crew members to be transported to a local hospital for additional evaluation, taking advantage of medical resources on Earth to provide the best care possible.

Following the planned overnight hospital stay, the crew members will return to NASA’s Johnson Space Center in Houston and undergo standard postflight reconditioning and evaluations.

This hospital visit for all four astronauts is simply a cover to hide which astronaut has the medical issue. At some point this information must be revealed, simply because it impacts how future space travel will be planned.

Endeavour undocks from ISS, carrying the Expedition-11 crew

8:19 pm

SpaceX’s Endeavour Dragon capsule undocked from ISS late this afternoon, carrying its four Expedition-11 crew who are coming home a few weeks early because of a medical issue with one crew person.

Live return coverage will resume at 2:15 a.m. Thursday, Jan. 15 on NASA+, Amazon Prime, and the agency’s YouTube channel until Dragon splashes down at approximately 3:41 a.m. off the coast of California and crew members are safely recovered.

It has been speculated by several sources, based on several NASA updates, that the crewman with the medical issues is Mike Finke, 58, who had flown in space three times previously.

Note that the only reason most major news sources are covering this crew return is because of the medical emergency. Normally, SpaceX has made this process so routine few pay attention any longer.

Because Boeing did nothing to replace a defective part, an airplane crashed killing fifteen

5:10 pm

MD-11 crash from November 2025
Click for NTSB report.

Despite previously identifying stress fractures in a part that held the engines to the wing on three different MD-11 airplanes, Boeing did nothing to replace the part, and so fifteen people died when the engine fell off a UPS cargo plane at take-off in November 2025.

The sequence of images to the right, which I have annotated to show the engine breaking free from the wing, comes from the NTSB preliminary investigation report [pdf]. From the article at the link above:

In an update to its ongoing investigation into the crash of UPS Flight 2976, the National Transportation Safety Board [NTSB] said its team found fatigue cracking and overstress failure across much of the bearing race inside the area that attached the plane’s left engine to its wing. NTSB investigators then went back into Boeing service data and confirmed the design of the bearing assembly was consistent with the original design of that part.

[A] Boeing Service Letter dated Feb. 7, 2011 [and found by the NTSB], told operators the company was aware of four previous bearing race failures on three different airplanes. Boeing had seen the fractures of the bearing race, with the parts splitting in two and moving out of place. However, Boeing told operators its review of the bearing failure “would not result in a safety of flight condition.”

Boeing said further regular inspection of MD-11 airplanes would include a look at this bearing assembly, something scheduled for 60-month service intervals. And while Boeing used that service letter to discuss a new bearing assembly configuration, the installation of the original parts “was not prohibited.”

The plane itself had been built by McDonnell-Douglas, prior to its merger with Boeing. Nonetheless, Boeing engineers and managers were aware of this issue and did nothing to inform the owners of this plane so they could take action. In fact, Boeing apparently continued to ship out the original parts to airlines as replacement spares.

This is another example of a serious quality control problem at Boeing, where engineers no longer view serious engineering failures as serious engineering failures.

Axiom has delayed the launch of its first space station module to ’28

11:53 am

Axiom's module assembly sequence
Axiom’s module assembly sequence

When Axiom announced in September 2025 that Redwire would be building the solar panels for the first module of its space station, dubbed the PPTM, it also said that module would launch in late 2027, which was a delay of one year from the original launch date of 2026.

That schedule has now apparently been delayed again. In an interview yesterday, the company’s vice president of human spaceflight, former NASA astronaut Peggy Whitson, indicated the launch was now targeting 2028.

Plans call for the initial Axiom Station to be comprised of two modules, the PPTM — short for Payload Power Thermal Module — and a habitat module. The PPTM, which is to be shipped shortly to Houston for final assembly and integration, is slated to be launched in early 2028, with the second module following just months later. From there, Axiom aims to swiftly begin welcoming crew, Peggy Whitson, the company’s vice president of human spaceflight, told me in an interview.

This schedule almost guarantees that the Axiom station will not detach from ISS as quickly as originally intended. PPTM has a large hatch opening connecting it to ISS, allowing for the easy transfer of much of the research racks held on ISS. Before Axiom can become a free-flying station that ISS equipment must be moved, a process that will take time, likely months. To get it done the company will probably have to also attach its second habitation module so that crews can arrive and begin this transfer process.

In other words, Axiom’s schedule margins for getting its station launched, docked to ISS, loaded with ISS equipment, and then separated before ISS retires in 2030 are shrinking. It can ill afford further delays.

Below are my rankings of the five American space stations presently under development. Note that I now consider Axiom and Starlab tied for second.
