The insane terrain inside Mars’ Death Valley

12:30 pm

taffy terrain
Click for original image.

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

The science team labels this a “twisted surface,” to which I think we all can agree. What we are looking at is a geological feature found only on Mars in only one region that has been labeled “taffy terrain” by scientists. According to a 2014 paper, the scientists posit that this material must be some sort of “a viscous fluid,” naturally flowing downward into “localized depressions.” Because of its weird nature I have posted many cool images of it in the past (see here, here, here, here, here, and here).

In the case of the image to the right, the red dot marks the peak of a small knob, with the green dot on the upper left the low point about 900 feet below. As you can see, the taffy has migrated into the depressions, as some flowing material would.

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

Ground-based telescope actually photographs an exoplanet

10:51 am

exoplanet imaged directly
Click for original movie.

Using a new instrument on the Subaru Telescope in Hawaii astronomers have not only discovered a massive exoplanet orbiting a star, they have been able to actually photograph the planet itself.

The arrow in the picture to the right shows that planet. That picture is a screen capture from a short movie complied from five observations taken over several months earlier this year, showing the planet as it orbited the star, the light of which is blocked out so as to not blind the camera. From the press release:

The newly discovered planet, HIP 54515 b, orbits a star 271 light-years away in the constellation Leo. With nearly 18 times Jupiter’s mass, it circles its star at about Neptune’s distance from our Sun. But the star and planet appear very close when seen from Earth; roughly the size that a baseball seen 100 km away would appear. The SCExAO system produced extremely sharp images allowing us to see the planet.

The astronomers also used this new instrument to image a brown dwarf star with a mass equivalent to sixty Jupiters about 169 light years away.

Yesterday’s Senate nomination hearing for Jared Isaacman was irrelevant; America’s real space “program” is happening elsewhere

10:20 am

Jared Isaacman
Billionaire Jared Isaacman

Nothing that happened at yesterday’s Senate hearing of Jared Isaacman’s nomination to be NASA’s next administrator was a surprise, or very significant, even if most media reports attempted to imply what happened had some importance. Here are just a small sampling:

To be fair, all of these reports focused on simply reporting what happened during the hearing, and the headlines above actually provide a good summary. Isaacman committed to the Artemis program, touted SLS and Orion as the fastest way to get Americans back to the Moon ahead of the Chinese, and dotted all the “i”s and crossed all the “t”s required to convince the senators he will continue the pork projects they so dearly love. He also dodged efforts by several partisan Democrats to imply Isaacman’s past business dealings with Musk and SpaceX posed some sort of conflict of interest.

What none of the news reports did — and I am going to do now — is take a deeper look. Did anything Isaacman promise in connection with NASA and its Artemis program mean anything in the long run? Is the race to get back to the Moon ahead of China of any importance?

I say without fear that all of this is blather, and means nothing in the long run. The American space program is no longer being run by NASA, and all of NASA’s present plans with Artemis, using SLS, Orion, and the Lunar Gateway station, are ephemeral, transitory, and will by history be seen as inconsequential by future space historians.

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.

Leaving Earth cover

Leaving Earth: Space Stations, Rival Superpowers, and the Quest for Interplanetary Travel, can be purchased as an ebook everywhere for only $3.99 (before discount) at amazon, Barnes & Noble, all ebook vendors, or direct from my ebook publisher, ebookit.

Weird mottled terrain in the dry tropics of Mars

1:11 pm

Mottled ridges
Click for full image.

Cool image time! The picture to the right, cropped, reduced, and enhanced to post here, was taken on October 28, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled by the science team as “mottled ridged terrain,” it shows a relatively flat area of scattered broken-up flat-topped ridges and knobs, following no clear pattern of formation.

In trying to research this, I could only find one paper [pdf] discussing this kind of mottled ridges that did a survey of similar features across a large region to the northwest. That paper could not determine what caused such features, but came up with hypothesis. From the abstract:

While it is not possible to determine the precise formation mechanism of these polygonal ridge networks from our new data, their formation can be assessed in terms of three possibly separate processes: (1) polygonal fracture formation, (2) fracture filling and (3) exhumation. We find that polygonal
fracture formation by impact cratering and/or desiccation of sedimentary host deposits is consistent with our results and previous spectral studies. Once the polygonal fractures have formed, fracture filling by clastic dikes and/or mineral precipitation from aqueous circulation is most consistent with our results. Exhumation, probably by aeolian processes that eroded much of these ancient Noachian terrains where the ridges are present caused the filled fractures to lie in relief as ridges today.

To put this in plain terms, the initial polygon-patterned cracks were formed by either an impact or the drying out of the surface (similar to the cracks seen on dried mud here on Earth). Both could have contributed. Then material welled up from below, either lava or mud, that hardened to fill the cracks. Later erosion by wind stripped away the surface, leaving behind these broken ridges.

As always, the location adds some very interesting context.

Sunspot update: Sunspot activity again crashes far below predictions

11:17 am

It is the start of another month, so it is time again to post my monthly update of the never-ending sunspot cycle on the Sun, using NOAA’s own monthly update of its graph of sunspot activity and annotating it with extra information to illustrate the larger scientific context.

The green dot on the graph below indicates the level of sunspot activity on the Sun’s Earth-facing hemisphere during the month of November. And once again, the Sun surprised us, producing far less sunspots than expected, based on the April 2025 prediction by NOAA’s panel of solar scientists (as indicated by the purple/magenta line).

France’s space agency CNES found liable for environmental damage at French Guiana spaceport

9:36 am

French Guiana spaceport

Click for full resolution image. (Note: The Ariane-5 pad is now the
Ariane-6 pad.)

France’s space agency CNES, which has taken back management from Arianespace of the French Guiana spaceport it owns, has now been found liable for destroying a protected habitat as it began construction to upgrade the old abandoned Diamant rocket launch site into a pad for several of Europe’s new commercial rocket startups.

In March 2022, the regional environmental authority of French Guiana (DGTM) formally informed CNES that it could not begin demolition or earthworks at the Diamant site without first securing the legally required species and water-law authorisations. Despite this, the agency leveled the area in the preceding weeks, with the environmental NGO CERATO discovering the destruction in April 2022.

In August 2022, the DGTM carried out an unannounced inspection of the Diamant site and found further destruction of protected habitats linked to the agency’s PV2 solar farm project. In October 2022, the PV2 project manager informed DGTM that CNES had known about the presence of protected species on the PV2 site since 1 July 2022, yet began earthworks anyway.

In response to repeated flouting of DGTM procedures, the Prefect of French Guiana, the top regional authority, issued a stop-work order requiring CNES to halt all works at both sites.

It appears this stop-work order has contributed to delays in construction. The news now is that the case appears to have been settled.

The agency has been ordered to repair the damage within three years or face a fine of €50,000. It will also be required to finance ecological compensation actions elsewhere on the grounds of the Guiana Space Centre. The conclusion of the lawsuit will allow the agency to fully resume construction at the site, which it had been ordered to stop in late 2022.

In other words, CNES has been told to spend money elsewhere at the spaceport to make the local environmental authorities happy. It remains unclear how these delays have or even will impact the plans of the Spanish rocket startup PLD, which hopes to do the first orbital launch of its Miura-5 rocket from this site in 2026. PLD expects the first flight-worthy Miura-5 to be delivered to French Guiana early next year, so the delays in French Guiana have not yet effected its plans. That might now change if the site won’t be ready as planned.

This whole story however does indicate a fundamental problem within all of Europe’s space regulatory infrastructure that in the future is likely to hinder the development of its new commercial space industry. Europe’s leadership likes its red tape, and has done nothing to reduce it as it has shifted from the government-run model (where it controls and owns everything) to the capitalism model (where it buys what it needs from an independent competing private sector).

Russian astronaut kicked out of the U.S. for stealing proprietary SpaceX designs

9:10 am

A Russian astronaut scheduled to fly on the next upcoming Dragon mission to ISS as part of the barter agreement between NASA and Roscosmos, has been removed from that mission after being caught taking pictures of SpaceX equipment in violation of State Department ITAR regulations.

Russian cosmonaut Oleg Artemyev has been removed from the prime crew of SpaceX’s Crew-12 mission to the International Space Station and replaced by fellow Roscosmos cosmonaut Andrey Fedyaev after sources alleged he photographed confidential SpaceX materials in California in violation of US export control rules, according to The Insider on December 2.

The outlet reported that Trishkin also said NASA did not want the controversy around Artemyev to become public, while Artemyev was removed from training at SpaceX’s Hawthorne California, facility last week after allegedly photographing SpaceX engines and other internal materials on his phone and taking them off-site.

The sources for this story all come from within Russia but it appears the story is true. It now appears that when the next manned Dragon launches to ISS in February, Fedyaev will fly instead of Artemyev.

The irony of this is that Russia doesn’t really have the capability of developing a comparable SpaceX rocket using this information. If anything, it would be more likely for Russia to sell the information to China in exchange for military hardware it could use in the Ukraine.

Either way, this violation by Artemyev of ITAR does not speak well for the future of the U.S./Russian partnership in space. It will certainly continue until ISS is retired, but this incident cements the likelihood that it will then end. None of the American commercial stations have shown any interest in signing agreemennts with Russia, though they all have signed numerous international deals, some with former Soviet bloc nations and even former Soviet provinces. After ISS Russia will be on its own.

And based on its inability to develop anything new in the past three decades, don’t expect much from it in space.

New data from VLT uncovers numerous debris disks around stars

9:01 am

A sampling of debris disks
Click for original

Using a new instrument on the Very Large Telescope (VLT) in Chile, astronomers have compiled a catalog of 51 potential exoplanet solar systems, all with intriguing debris disks surround the stars with features suggesting the existence of asteroids and comets.

The image to the right shows a sampling of those systems. From the press release:

“To obtain this collection, we processed data from observations of 161 nearby young stars whose infrared emission strongly indicates the presence of a debris disk,” says Natalia Engler (ETH Zurich), the lead author of the study. “The resulting images show 51 debris disks with a variety of properties — some smaller, some larger, some seen from the side and some nearly face-on – and a considerable diversity of disk structures. Four of the disks had never been imaged before.”

Comparisons within a larger sample are crucial for discovering the systematics behind object properties. In this case, an analysis of the 51 debris disks and their stars confirmed several systematic trends: When a young star is more massive, its debris disk tends to have more mass as well. The same is true for debris disks where the majority of the material is located at a greater distance from the central star.

Arguably the most interesting feature of the SPHERE debris disks are the structures within the disks themselves. In many of the images, disks have a concentric ring- or band-like structure, with disk material predominantly found at specific distances from the central star. The distribution of small bodies in our own solar system has a similar structure, with small bodies concentrated in the asteroid belt (asteroids) and the Kuiper belt (comets).

The data from various telescopes both on the ground and in space is increasingly telling us that our solar system is not unique, and that the galaxy is filled with millions of similar systems, all in different states of formation. This hypothesis is further strengthened by the appearance of interstellar comet 3I/Atlas, which despite coming from outside our solar system is remarkably similar to the comets formed here.

China’s Zhuque-3 copycat Falcon 9 reaches orbit on first launch; 1st stage crashes

10:32 pm

Zhuque-3 at launch
Screen capture from China’s
state-run press

The methane-fueled Zhuque-3 rocket built by China’s Landspace pseudo-company successfully reached orbit today on its first launch, though the attempt to land the first stage vertically for later reuse failed when it crashed near its landing zone.

The reusable rocket, designed by the Beijing-based commercial space company LandSpace, was launched from the Jiuquan Satellite Launch Centre in China’s northwest at noon on Wednesday. After reaching a low-Earth orbit, the first stage of the rocket – the lower section that lifts the vehicle off the ground – appeared to catch fire in the air before crashing near the target recovery site.

I think a video of that failed landing can be seen here, though I cannot be sure, as it appeared to go up on youtube immediately at launch time, almost too soon.

For the Landspace pseudo-company, getting this rocket to orbit on the first try is a major success. It plans several more launches in the coming months, with each attempting a similar landing. Based on SpaceX’s history in this matter, it should not take it long to achieve its first landing success.

The leaders in the 2025 launch race:

158 SpaceX
75 China (a new record)
15 Rocket Lab
15 Russia

SpaceX still leads the rest of the world in successful launches, 158 to 127.

SpaceX today successfully launched another 29 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its 25th flight, landing on a drone ship in the Atlantic. With this flight, this booster, B1077, has now tied the space shuttle Endeavour in reuses, and is only three behind the Columbia shuttle.

The leaders in the 2025 launch race:

158 SpaceX (a new record)

Astronomers detect another galaxy that shouldn’t be there, so soon after the Big Bang

11:38 am

A spiral galaxy too early in the universe
Click for original.

Using the Webb Space Telescopes astronomers have detected another galaxy that shouldn’t be there, so soon after the Big Bang.

The image to the right comes from figure 1 of the peer-reviewed paper. The galaxy’s two spiral arms form a backward “S” emanating out from the galaxy’s nucleus. From the press release:

Using JWST, researchers Rashi Jain and Yogesh Wadadekar spotted a galaxy remarkably similar to our own Milky Way. Yet this system formed when the cosmos was barely 1.5 billion years old—roughly a tenth of its present age. They named it Alaknanda, after the Himalayan river that is a twin headstream of the Ganga alongside the Mandakini—fittingly, the Hindi name for the Milky Way.

…It already has two sweeping spiral arms wrapped around a bright, rounded central region (the galaxy’s ‘bulge’), spanning about 30,000 light-years across. Even more impressively, it is annually churning out new stars, their combined mass roughly equivalent to 60 times the mass of our Sun. This rate is about 20 times that of the present-day Milky Way! About half of Alaknanda’s stars appear to have formed in only 200 million years—a blink in cosmic time.

This galaxy underlines the difficulty for cosmologists by much of Webb’s data of the early universe. Present theories of galaxy formation say it should take billions of years to form such a spiral galaxy, meaning it shouldn’t exist as yet so soon, only 1.5 billion years after the Big Bang.

Either the theories have to be revised substantially, or they are simply wrong entirely. Or we are missing or lacking in some fundamental information about the early universe that skews all our theories.

Blue Origin faces opposition renewing its permit to dump waste water at Florida launch facility

11:17 am

Chicken Little strikes again!
Chicken Little strikes again!

It appears several local politicians as well as the typical anti-everything activists are expressing opposition to Blue Origin’s request to renew its permit to dump waste water at its Florida launch facility.

Some county commissioners have concerns about the proposal because of how much money and effort has gone to cleaning up the Indian River. “That’s really troubling to me especially when we are spending so much money as a community on the half-cent sales tax and the save the Indian River Lagoon tax,” said Brevard County Commissioner Katie Delaney.

Space experts say large-scale companies don’t necessarily follow rules and regulations put on them. “There has been all sorts of industrial waste issues associated with the aerospace industry not just here in Florida but all across the country,” Florida Tech space professor, Don Platt, said.

The water is likely that used during launches to dampen the shock produced by the rocket’s engines, and like SpaceX’s systems, is almost certainly potable and harmless. This is also a permit that Blue Origin obtained five years ago and has used without harm during all its launchpad tests and launches.

None of this whining really matters, as it appears the county commission has no authority over the matter. The permit was issued by the state’s environmental department which will almost certainly approve the renewal. It is just unfortunate that these whiners almost always get positive coverage from our propaganda press. In this case the local Fox affiliate that reported the story clearly made no effort to research anything. It just simply spouted back the grumbles of these politicians and activists.

Three new papers find sugars, “gum,” and lots of stardust in the samples brought back from the asteroid Bennu

10:24 am

Bennu
The asteroid Bennu

Three new papers published this week have found that the samples brought back by OSIRIS-REx from the asteroid Bennu contained some unexpected or unusual materials, including sugars that are important for biology, a gumlike material never seen before, and a much higher amount of stardust than expected.

The papers can be read here, here, and here.

As the press release notes, describing the sugar discovery:

The five-carbon sugar ribose and, for the first time in an extraterrestrial sample, six-carbon glucose were found. Although these sugars are not evidence of life, their detection, along with previous detections of amino acids, nucleobases, and carboxylic acids in Bennu samples, show building blocks of biological molecules were widespread throughout the solar system.

The stardust results found six-times the abundance previously found in other samples.

As for the “gum”, this was possibly the strangest discovery of all, coming from the solar system’s earliest time period.

All eight ports on ISS occupied for the first time; Longest manned mission about to start?

9:56 am

ISS as presently configured
ISS as presently configured. Click for original.

For the first time in its more than quarter century history, all eight docking ports on ISS are occupied, as shown in the graphic to the right.

For the first time in International Space Station history, all eight docking ports aboard the orbital outpost are occupied following the reinstallation of Northrop Grumman’s Cygnus XL cargo spacecraft to the Earth-facing port of the station’s Unity module. The eight spacecraft attached to the complex are: two SpaceX Dragons, Cygnus XL, JAXA’s (Japan Aerospace Exploration Agency) HTV-X1, two Roscosmos Soyuz crew spacecraft, and two Progress cargo ships.

This milestone follows the reattachment of the Cygnus XL spacecraft, supporting the Northrop Grumman-23 commercial resupply services mission for NASA, which was removed last week by the robotics officer at the agency’s Mission Control Center in Houston using the space station’s Canadarm2 robotic arm. The Cygnus XL movement was coordinated between NASA, Northrop Grumman, and Roscosmos to provide appropriate clearance for the arriving crewed Soyuz MS-28 spacecraft on Nov. 27.

Cygnus will remain attached to the orbiting laboratory until no earlier than March 2026, when it is scheduled to safely depart and dispose of up to 11,000 pounds of trash and unneeded cargo when it harmlessly burns up in Earth’s atmosphere.

This situation will not last of course, and in fact it may never happen again before the station is retired around 2030. First, Cygnus will leave in March. Second, one Russian Soyuz capsule will leave shortly, as the presence of two simply indicates a crew rotation is underway.

Third, it is presently unclear when the Russians will be able to launch further Soyuz or Progress capsules. » Read more

China reveals its plans for the damaged Shenzhou-20 capsule docked to Tiangong-3

9:28 am

The Tiangong-3 station, as presently configured
The Tiangong-3 station, as presently configured,
with two Shenzou capsules docked at either end.

Having successfully docked Shenzhou-22 as a lifeboat to its Tiangong-3 space station last week, China’s state-run press yesterday outlined its plans for the damaged Shenzhou-20 capsule that is still docked to the station but cannot be used by its crew because of cracks in one viewport.

First, China’s space operations have decided to attempt a return of the capsule back to Earth, unmanned, so the damage can be inspected in greater detail. Before that happens however the astronauts on board the station will do their own inspection, including the possibility of adding a patch.

During a subsequent spacewalk, the Shenzhou-21 crew, who are now undertaking a six-month orbital stay, may be tasked with inspecting the cracked viewport. They may also perform protective work on it using specialized devices delivered by the Shenzhou-22 launch — a procedure still being validated in ground tests, said Ji in a recent CCTV interview.

A day prior to their planned return on Nov. 5, the Shenzhou-20 crew spotted an anomaly on the viewport’s edge — a triangular, paint-like mark. They photographed it from multiple angles and under different lights, while the station’s robotic arm cameras were employed to take supplemental external pictures.

The flaw was later identified as “penetrating cracks,” said Jia Shijin, chief designer of the crewed spaceship system from China Academy of Space Technology. “The space debris responsible is preliminarily judged to be less than a millimeter in size, but struck with extremely high speed.”

This description of the damage is the most detailed China as yet revealed. These details certainly fit the description of an impact from an outside source, though considering China’s general lack of transparency some skepticism should still be retained. For example, we still do not know if these “penetrating cracks” mean the capsule is no longer holding its atmosphere, or if the crew has closed the capsule’s hatch to keep the air loss to a minimum.

Either way, it appears China’s engineers are concerned that this damage could cause a major break-up of the capsule during re-entry, and are thus considering options for covering it during that return.

German rocket startup Isar gets launch contract from ESA

8:25 am

The German rocket startup Isar Aerospace yesterday announced it has won a launch contract from the European Space Agency (ESA) to place a satellite carrying a number of experimental payloads into orbit before the end of 2026.

Satellite launch service company Isar Aerospace has signed a contract with the European Space Agency (ESA) to launch the ΣYNDEO-3 mission under the European Union’s In-Orbit Demonstration and In-Orbit Validation Programme (IOD/IOV). The launch will be carried out from Isar Aerospace’s dedicated launch complex at Andøya Space in Norway from Q4 2026.

…Redwire is the prime contractor for the ΣYNDEO-3 mission and will be delivering its Hammerhead spacecraft for a launch onboard Isar Aerospace’s launch vehicle Spectrum to a low Earth orbit (LEO). The spacecraft was built and integrated at Redwire’s state-of-the-art satellite processing facility in Belgium. The spacecraft aggregates 10 innovative payloads from six countries and institutions: Spain, France, Germany, Italy, Luxembourg and the EC.

Isar has yet to reach orbit with its Spectrum rocket. The first launch failed in March only seconds after launch. A second attempt is presently scheduled for sometime prior to December 21, 2025, lifting off from Andoya.

This is the second new launch contract Isar has announced in the past two weeks, and the third since September. At the moment it appears it is gaining momentum pending that first launch later this month, especially because a successful December launch would make it the first European rocket startup to successfully reach orbit.

Senate Commerce committee to move up its vote on Isaacman’s nomination as NASA administrator

8:01 am

Jared Isaacman
Billionaire Jared Isaacman

Today Senator Ted Cruz (R-Texas) announced that the Commerce committee he heads will vote on the re-nomination of Jared Isaacman for NASA administration on December 8, 2025, only five days after tomorrow’s renomination hearing.

It appears Cruz and his committee is pushing to get Isaacman approved as quickly as possible. At least one Republican senator, John Cornyn (R-Texas) has met with Isaacman again and gotten his commitment to move the space shuttle Discovery to Texas, as mandated by the budget bill passed several months ago. That commitment was likely a quid pro quo by Cornyn to get his vote for Isaacman.

Once Isaacman is approved by Cruz’s committee, the Senate could vote at any time. Whether it will do so before the end of the year remains unknown, as it would likely require a special session as the Senate is expected to be in recess until after the new year.

If it does not, it will likely give Isaacman very little time to review the next Artemis mission, tentatively schedule for launch as early as February 2026, carrying four astronauts around the Moon on a Orion capsule with a questionable heat shield and an untested environmental system.

SpaceX gets Air Force approval to launch and land Starship/Superheavy at Cape Canaveral

12:01 am

Cape Canaveral

The Air Force announced late yesterday [pdf] that it will now allow SpaceX to launch its Starship/Superheavy rocket at Space Launch Complex 37 (SLC-37) at Cape Canaveral in Florida (as shown on the map to the right) as many as 76 times per year, with twice that number of landings.

The DAF [Department of Air Force] decision authorizes SpaceX to use SLC-37 at CCSFS [Cape Canaveral Space Force Station] to support Starship-Super Heavy launch and landing operations, including the redevelopment of SLC-37 and the other infrastructure improvements required and analyzed in the FEIS [Final Environmental Impact Statement]. Under this ROD [record of decision], upon execution of the real property agreement and associated documentation, and as analyzed in the FEIS while adhering to the mitigation measures specified in Appendix A to this ROD, SpaceX is authorized to: (1) undertake construction activities necessary to re-develop SLC-37 and associated infrastructure for Starship Super Heavy operations; (2) conduct prelaunch operations, including the transportation of launch vehicle components and static fire tests; and (3) conduct up to 76 launches and 152 landings annually once a supplemental analysis of airspace impacts by the Federal Aviation Administration (FAA) is completed. [emphasi mine]

The deal also requires SpaceX to do some road upgrades in order to transport the rocket from its Gigabay to the launch tower. The company immediately announced on X yesterday that it has already begun construction, and expects to have three pads in Florida before all is done.

The final environmental impact statement [pdf] was released on November 20, 2025, and concluded in more than 200 pages that there will be no significant impact from these launch operations, something that should be self-evident after more than three-quarters of century of rocketry at the Cape. The existence of the spaceport acts to protect wildlife, because it limits development across a wide area.

The report suggested that some turtle species and one mouse specie might “affected adversely”, but it it also appears that risk was considered minor and not enough to block development. To deal with this however the impact statement requires SpaceX to do a number of mitigation actions, similar to what it is required to do at Boca Chica.

One fact must be recognized, based on the red tape and delays experienced by SpaceX during the Biden administration. Had Kamala Harris and the cadre that ran the White House under Biden had been in office now, this approval would almost certainly have not happened, or if it did, it would have likely been delayed for a considerable amount of time, into next year at the earliest. It is certain that Trump is clearing the path to prevent red tape and the administrative state from slowing things down unnecessarily.

This announcement also strengthens the likelihood that SpaceX will do at least one launch of Starship/Superheavy from Florida in 2026. And if not then, by 2027 for sure.

Two launches today, by Arianespace and SpaceX

10:36 pm

Today there were two launches worldwide, one from South America and the second from the U.S.

First, Arianespace launched a South Korea imaging satellite from French Guiana, using the Vega-C rocket built and owned by the Italian rocket company Avio. Based on the July 2024 agreement, this is the next-to-last Vega-C flight that Arianespace will manage. After the next flight, Avio will take over management of its own rocket, cutting out this government middle man, though that agreement also allowed customers who had previously signed with Arianespace for later flights to stay with it as the managing organization.

Either way, Arianespace’s responsibilities will soon be limited solely to the Ariane-6 rocket, which itself has a limited future, being expendable and too expensive to compete in the present launch market.

Next SpaceX launched another 27 Starlink satellites into orbit, its Falcon 9 lifting off from Vandenberg Space Force Base in California. The first stage completed its 20th flight, landing on a drone ship in the Pacific.

As the Vega-C launch was only the sixth for Europe in 2025, it remains off the leader board for the 2025 launch race:

157 SpaceX (a new record)
74 China
15 Rocket Lab
15 Russia

SpaceX now leads the rest of the world in successful launches, 157 to 126.

Buffalo Bill: The greatest true boy adventure story that’s never been told

1:14 pm

The Lives and Legends of Buffalo Bill

In American popular culture, Buffalo Bill is an icon whose history we all think we know, a western showman who in the latter decades of the 19th century traveled the world with his Wild West show, enchanting heads of states as well as ordinary people with the romantic fantasy of the American west, made up of wagon trains, gunfighters, Indian attacks, and last-minute cavalry rescues.

His name inspired the name of a professional football team. His Wild West show inspired at least one musical and numerous Hollywood movies and television shows.

Yet do we really know who the man was?

I discovered recently that we do not. Our culture knows nothing about the man, whose real name was William Cody. Worse, its cartoon vision of him denigrates his unique American nature. He was not only the greatest scout the U.S. Army ever saw, his knowledge of American Indian made it possible for him to not only help make peace with those Indians who wanted it, it also helped the U.S. put down those Indians willing only to wage terrorist war. And when he shifted into the entertainment world, his show provided employment for both his many cowboy friends as well as for many of those same Indians, both friends and former enemies.

And most astonishing of all, I discovered that Buffalo Bill’s childhood was one of the most amazing boy adventure tales, far more exciting than any kid’s movie made in the last hundred years. That Hollywood has never made a movie of his youth now baffles me. It is the stuff that Hollywood craves, but more significantly, it appears it actually happened!

I discovered these facts in reading Don Russell’s wonderful biography of Bill Cody, The Lives and Legends of Buffalo Bill, published by the University of Oklahoma in 1979. Russell’s focus was to dig into the original source material in order to separate the fact from the fiction, since much of Cody’s life had been exaggerated by himself and others during his showman days, and then overblown and warped by Hollywood’s later interpretations.

In this Russell succeeds brilliantly. He describes what we know in vivid language, but also outlines what we don’t know or can’t trust about each story. In the end he describes a unique man with unique talents who always tried to do the right thing, even in difficult circumstances. In every sense Cody’s life was the epitome of an American western pioneer cowboy, pushing the unknown with courage and pluck.

But to me the most amazing part of Russell’s biography was its first few chapters, when Russell describes Cody’s childhood. The boy’s father, Isaac Cody, was a pioneer in his own right, taking his family farther and farther west until they ended up in Kansas and involved in the violent politics there preceding the Civil War. When Isaac died in 1857, he left behind a widow and three young children, who then had to find a way to survive in that difficult pioneer world.

And so, at the age of eleven Billy Cody went out to find work. And the work the boy found was truly astonishing, when compared to what we expect from kids his age today.

A detailed look at Europe’s $1 billion commitment to its nascent commercial rocket industry

11:12 am

The European Space Agency

Link here. In announcing last week the European Space Agency’s (ESA) budget for the next three years, along with its general overall goals, the European council (dubbed CM-25) also apparently committed about $1.45 billion to its “European Launcher Challenge”, a program created in 2023 and designed to encourage the development of new European rockets, owned and operated by independent competing startups.

The article at the link provides a good overall summary of major increase in funding for this program, including which ESA countries are contributing the most and why. The key quote however is this:

In July 2025, ESA shortlisted Isar Aerospace, Rocket Factory Augsburg, PLD Space, MaiaSpace, and Orbex to proceed to the initiative’s next phase. It then began discussions with the host country of each company to assess its willingness to contribute to that company’s participation in the European Launcher Challenge.

During his post-CM25 address, ESA Director General Josef Aschbacher revealed that Member States had committed double the anticipated amount for the European Launcher Challenge, with the final figure exceeding €900 million. While the funding model’s structure suggests that only the UK, Spain, France, and Germany contributed, post-CM25 disclosures have indicated that a few additional countries also committed funds to the programme.

Germany appears to be the biggest contributor, supplying more than a third of the total fund ($422 million). This isn’t surprising, since Germany also has the most rocket startups, three, two of which are on that shortlist (Rocket Factory and Isar). Spain is next with a contribution of $196 million, aimed helping the rocket startup PLD. The UK is next, also contributing $196 million, likely to be used to support its Orbex startup that wants to launch from its Saxavord spaceport in the Shetland Islands.

A variety of other ESA nations, the Czech Republic, the Netherlands, and Norway, have also outlined their contributions, for a variety of space-related startups unrelated to rockets.

France also appears to have donated a significant amount, but has not made that number public. Its MaiaSpace startup is one on that shortlist above, but France also has one or two other rocket startups that might eventually qualify for aid.

The bottom line is that ESA here is committing funding to aid the development of rockets and space infrastructure that it won’t own or control, a major shift from its past policy of owning and controlling everything through its Arianespace pseudo-commercial company, what I call the Soviet- or government-run model. Instead, these ESA nations are going to help fund a range of competing private rockets, which will own the rockets and operate them for profit. ESA will simply become one of their customers, following the capitalism model that the U.S. switched to in the previous decade.

This increased commitment to capitalism in the ESA suggests that we should see some real progress by these startups in the next three years.

If you think the launch records being set this year are breath-taking, you ain’t seen nothin’ yet.

After being linked for almost six months, China’s Shijian 21 and Shijian 25 separate

9:32 am

After rendezvousing and doing repeated docking tests in June and July and then remaining linked since then, China’s Shijian 21 and Shijian 25 test satellites have now separated.

Optical ground observations Nov. 29 made by S2a systems, a Swiss company which develops and operates customized systems for optical space surveillance worldwide, reveal that the two satellites have now separated in geosynchronous orbit, close to the geostationary belt (GEO) at 35,786 km above Earth’s equator. The orbits of the pair are inclined by 4.6 degrees with respect to GEO.

The article at the link speculates that the spacecraft were doing refueling tests while docked, but while a good guess this has not been confirmed anywhere. China has said nothing.

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, apparently intended to test robotic servicing of satellites. These maneuvers with Shijian-21 appear to be part of those tests. Whether those tests included refueling is uncertain, though possible. If Shijian-21 proceeds to do additional satellite tug maneuvers then it will strongly suggest this refueling occurred and was successful.
