Annual February birthday fund-raising campaign for Behind the Black

12:13 am

Scroll down for the most recent stories.

Please forgive this pleading appeal, but to survive I have to do several fund-raising campaigns each year. Please consider helping me celebrate my 73rd birthday this month by donating or subscribing to Behind the Black.

As I have noted repeatedly, I am routinely ahead of the curve in analyzing the news and what it means for the future. Fifteen years ago I said NASA’s SLS rocket was garbage and should be cancelled. Almost a decade ago I said its Orion capsule was a lie and a bad idea. As early as 1998, long before almost anyone else, I predicted in my first book, Genesis: The Story of Apollo 8, that private enterprise and freedom would conquer the solar system, not government. And while everyone else in the media still thinks Mars has no water, I have been reporting the real results from the orbiters now for more than five years, that Mars is in fact a planet largely covered with ice.

I could provide many more examples. If you want to know what others will discover a decade hence, read what I write here at Behind the Black. Read my history books if you want to find out why the initial exploration of the solar system has transpired as it has. You will also find out what is going to happen in the next century.

Though it might sound like I am bragging with this last claim, my overall track record bears it out.

So please consider donating or subscribing to Behind the Black, either by giving a one-time contribution or a regular subscription. I could really use the support at this time. There are five ways of doing so:

1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get. (Note: if your bank requests you reference “Diane Zimmerman” in using my email address, do so. We are temporarily using one of her accounts, tied to my email address.)

2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation. Takes about a 10% cut.

3. A Paypal Donation or subscription, which takes about a 15% cut:




4. Donate by check, payable to Robert Zimmerman. What you give is what I get. Mail checks to:

Cortaro, AZ 85652

5. Finally, you can also support me by buying one of my books, as noted in the boxes interspersed throughout the webpage or shown in the menu above.

This post will remain at the top of the page until the end of the month.

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

Isaacman: SLS stands on very thin ice

2:46 pm

Though NASA administration Jared Isaacman continues to support unequivocally NASA’s planned Artemis-2 ten-day manned mission around the Moon — presently targeting a March launch date — in a statement today on X he revealed that he also recognizes the serious limitations of the SLS rocket.

And it takes two-plus years between launches
And it also takes two-plus years between launches

The Artemis vision began with President Trump, but the SLS architecture and its components long predate his administration, with much of the heritage clearly traced back to the Shuttle era. As I stated during my hearings, and will say again, this is the fastest path to return humans to the Moon and achieve our near-term objectives through at least Artemis V, but it is not the most economic path and certainly not the forever path.

The flight rate is the lowest of any NASA-designed vehicle, and that should be a topic of discussion. It is why we undertake wet dress rehearsals, Pre-FRR, and FRR, and why we will not press to launch until we are absolutely ready.

These comments were also in connection with the first wet dress rehearsal countdown that NASA performed with SLS/Orion in the past few days, a rehearsal that had to be terminated early because of fuel leaks. NASA now plans to do another wet dress rehearsal, requiring it to push back the Artemis-2 launch until March.

I think there is more going on here than meets the eye.

Pluto and Charon come out of the dark

1:40 pm

Pluto and Charon come out of the dark
Click for original image.

Cool image time! I have decided to start delving into the archives of some of the older planetary missions, because there is value there that is often forgotten now years later, that should not be forgotten.

In looking through the archive of images from the main camera on New Horizons as it sped past Pluto in July 2015, I found the picture to the right, taken on July 10, 2025 when New Horizons was still about three million miles away.

This is the raw image from that camera, cropped, reduced, and sharpened to post here. It is also the first time in human history we had a sharp look at these two planets that sit at the outer fringes of the solar system. The science team that day released a version that they enhanced to bring out the details, which I immediately posted. They then noted the following:

A high-contrast array of bright and dark features covers Pluto’s surface, while on Charon, only a dark polar region interrupts a generally more uniform light gray terrain. The reddish materials that color Pluto are absent on Charon. Pluto has a significant atmosphere; Charon does not. On Pluto, exotic ices like frozen nitrogen, methane, and carbon monoxide have been found, while Charon’s surface is made of frozen water and ammonia compounds. The interior of Pluto is mostly rock, while Charon contains equal measures of rock and water ice. “These two objects have been together for billions of years, in the same orbit, but they are totally different,” said Principal Investigator Alan Stern of the Southwest Research Institute (SwRI), Boulder, Colorado.

This difference is quite clear in the raw image, with Charon markedly dimmer than Pluto even though they are getting the same amount of light from the Sun.

More than any other objects in the solar system, the double planet system of Pluto-Charon demonstrates how uniquely different every object in the solar system is from every other object. Even when formed together, as these two planets were, they formed in a manner that made them drastically different.

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.

Lawrence of Arabia: Truth is sometimes stranger than fiction

12:01 pm

Larence in Arabia

One of the 20th century’s greatest movies is David Lean’s 1962 epic Lawrence of Arabia. The story it tells — of the clash of cultures, of war, and of colonization — combined with the personal story of T.E. Lawrence during World War I, is one of high drama that is unforgettable to anyone who has ever seen it.

Yet, the events it tells seem too dramatic to be believed. Did Lawrence actually rescue a man in the desert, by himself and against the advice of his Arab allies who knew better? Did he actually later execute that man coldly to prevent a tribal war that would have destroyed the Arab revolt against the Ottoman Empire? Did he actually lead those Arab tribes across a deadly desert to take the town of Aqaba from the rear?

And did he actually lead that Arab revolt so successfully that it took Damascus ahead of the British, only to lose it because that medieval tribal culture knew nothing about modern technology?

For years I wondered about these questions and tried to find out. I read T.E. Lawrence’s own memoir of his time there, The Seven Pillars of Wisdom, and found it to be unclear and obscure, answering none of my questions. Other histories about World War I merely touched upon these events, treating them as a minor side show. And histories about the Middle East during that time seemed uninterested in telling this part of the story.

So, the questions remained: Did these events really happen? They seemed too good to be true.

I have now discovered that these stories are not only largely true, the reality of T.E. Lawrence’s life and his time in Arabia was even stranger than I could suppose. I learned this from Scott Anderson’s fine biography of Lawrence, Lawrence in Arabia: War, Deceit, Imperial Folly, and the Making of the Modern Middle East. Anderson not only unveiled Lawrence in all his inexplicable glory in this book, he made clear the complex political background that shaped the Middle East, and made it as we know it today.

Dumb science: Researchers claim Jupiter is 0.0028% thinner than previously measured

9:29 am

Stupidity on display: According to researchers using data from the Jupiter orbiter Juno, Jupiter is a tiny bit thinner at the equator and flatter at the poles than previously measured.

Leading an international team from Italy, the United States, France and Switzerland, Weizmann Institute of Science researchers [Israel] have produced more precise measurements of Jupiter’s size and shape than ever before, using new data from NASA’s Juno spacecraft.

The peer-reviewed research, published today in Nature Astronomy, shows that the radius of Jupiter is about four kilometers (2.5 miles) thinner at its equator and 12 kilometers (7.5 miles) flatter at the poles than believed in earlier assessments. The scientists determined the planet has a radius of 71,484 kilometers (44,418 miles). Earlier data measured it at 71,492 kilometers (44,423 miles).

The absurdity of this research is galling. The revision they claim is tiny, a mere 0.0028% difference at the equator, and 0.0084% at the poles. These numbers are insignificant. Moreover, Jupiter is a gas giant. It has no precisely known surface. Instead, it has an atmosphere that gradually thins as you go up. To claim any precise diameter is absurd, especially because seasonally and over time that atmosphere will expand and shrink.

And of course, at least two mainstream news outlets, Scientific American and The Times of Israel (linked above), report this story without any skepticism, as if this is a Earth-shaking discovery. All that tells me is that when it comes to science, both are incompetent sources of information.

India schedules next PSLV launch for June, claims it knows cause of January launch failure

9:10 am

India's space agency ISRO, as transparent as mud
India’s space agency ISRO,
as transparent as mud

According to a statement by a government minister yesterday, India’s space agency ISRO now knows what caused the January launch failure of its PSLV rocket, and has thus scheduled its next launch for June 2026.

This had been the second PSLV launch failure in a row, both of which occurred with the rocket’s third stage at almost the exact same time. With the first failure, ISRO never outlined publicly the cause, though it claimed it had solved the issue. According to the minister’s statement, the failure of the second launch was unrelated to the first.

The minister also said that the two PSLV missions that had failed—PSLV-C61 in May 2025 and PSLV-C62 in January this year—were unrelated. “It wasn’t the same problem. When the first mission failed, there was a detailed assessment, and the problem was fixed. Both the issues were different,” Singh said.

He also added that separate internal and external failure assessment committees have been set up to analyse what went wrong in each of the missions.

No word however as to the cause of the failure has yet been released. Though he also claimed the PSLV has not lost its customers due to these issues, ISRO’s lack of transparency says otherwise. If it claims the two failures came from different causes, it should provide the details in order to reassure potential customers.

NASA makes right decision and delays Artemis-2 launch to do a 2nd dress rehearsal countdown

8:53 am

Artemis Program logo

NASA management announced today that it has decided to postpone the launch of the manned Artemis-2 mission around the Moon until March in order to give it time to do a second wet dress rehearsal countdown of the rocket and fix the hydrogen fuel leaks that occurred in yesterday’s rehearsal.

Engineers pushed through several challenges during the two-day test and met many of the planned objectives. To allow teams to review data and conduct a second wet dress rehearsal, NASA now will target March as the earliest possible launch opportunity for the flight test.

Moving off a February launch window also means the Artemis II astronauts will be released from quarantine, which they entered in Houston on Jan. 21. As a result, they will not travel to NASA’s Kennedy Space Center in Florida Tuesday as tentatively planned. Crew will enter quarantine again about two weeks out from the next targeted launch opportunity.

It should be understood that these hydrogen leaks have been systemic to SLS’s core stage rocket engines, which come from the shuttle era. Shuttle launches were routinely delayed due to similar leaks. This was partly because hydrogen is extremely difficult to control, as its atom is so small and light, and partly because of the engine design. This was the first rocket system ever to use hydrogen as fuel, and was thus cutting edge, in the 1970s. We should not be surprised by such issues.

Newer hydrogen-fueled designs have apparently overcome the problem. For example, Blue Origin uses hydrogen as a fuel in the upper stage of its New Glenn rocket, and though it has only launched twice, it has not had such issues on either launch.

In its announcement NASA also noted a bunch of other issues that occurred during this first rehearsal, all of which suggest that a delay is called for. There was a valve issue in the Orion capsule, some audio communication channels kept dropping out, and the cold weather affected some equipment. Waiting until warmer weather will help alleviate some of this.

Falcon 9 upper stage has issue preventing de-orbit burn; SpaceX pauses launches

8:34 am

According to a SpaceX tweet yesterday afternoon, the upper stage of the Falcon 9 rocket that successfully launched 25 Starlink satellites “experienced an off-nominal condition” when it was preparing to do its final de-orbit engine burn.

During today’s Falcon 9 launch of @Starlink satellites, the second stage experienced an off-nominal condition during preparation for the deorbit burn. The vehicle then performed as designed to successfully passivate the stage. The first two MVac burns were nominal and safely deployed all 25 Starlink satellites to their intended orbit.

Teams are reviewing data to determine root cause and corrective actions before returning to flight

It appears that SpaceX has temporarily paused its launch schedule while it reviews this incident, shifting a launch that was supposed to occur last night back three days to February 5th. While the launch itself was successful, the company likely wants to get a handle on what went wrong before resuming launches.

Fuel leaks cause Artemis-2 dress rehearsal countdown to terminate at T-5:15, several minutes early

11:15 pm

Artemis Program logo

Two hydrogen fuel leaks during today’s Artemis-2 dress rehearsal countdown forced an early termination of the count as well as the cancellation of a second practice countdown.

The Artemis II wet dress rehearsal countdown was terminated at the T-5:15 minute mark due to a liquid hydrogen leak at the interface of the tail service mast umbilical, which had experienced high concentrations of liquid hydrogen earlier in the countdown, as well. The launch control team is working to ensure the SLS (Space Launch System) rocket is in a safe configuration and begin draining its tanks.

An earlier leak of hydrogen in the count forced a hold and a recycling of the count, though it did not stop the rehearsal.

The initial plan had been to do two terminal counts. First they would run the countdown down to T-33 seconds, hold for a few minutes, then recycle back to T-10 minutes and do it again. Because of that first leak delay the launch director canceled the second count. And because of the second leak they were unable to run that one count all the way to T-33 seconds.

The wise action would be for NASA to review their data, figure out what caused the leaks, correct it, and then do another dress rehearsal countdown. This being NASA, do not be surprised if they review the data, figure out what caused the leaks, and decide they can go ahead with the launch on February 8, 2026.

Why not? They are already launching this manned 10-day mission around the Moon with an untested life support system and a questionable heat shield. Might as well try a launch when you haven’t worked out all the fueling kinks.

Musk: I have merged xAI with SpaceX

3:35 pm

Elon Musk today announced that he has merged the company xAI (which includes X) with SpaceX, because in his mind the needs of the two companies interlace perfectly.

The requirement to launch thousands of satellites to orbit became a forcing function for the Falcon program, driving recursive improvements to reach the unprecedented flight rates necessary to make space-based internet a reality. This year, Starship will begin delivering the much more powerful V3 Starlink satellites to orbit, with each launch adding more than 20 times the capacity to the constellation as the current Falcon launches of the V2 Starlink satellites. Starship will also launch the next generation of direct-to-mobile satellites, which will deliver full cellular coverage everywhere on Earth.

While the need to launch these satellites will act as a similar forcing function to drive Starship improvements and launch rates, the sheer number of satellites that will be needed for space-based data centers will push Starship to even greater heights. With launches every hour carrying 200 tons per flight, Starship will deliver millions of tons to orbit and beyond per year, enabling an exciting future where humanity is out exploring amongst the stars.

The basic math is that launching a million tons per year of satellites generating 100 kW of compute power per ton would add 100 gigawatts of AI compute capacity annually, with no ongoing operational or maintenance needs. Ultimately, there is a path to launching 1 TW/year from Earth.

My estimate is that within 2 to 3 years, the lowest cost way to generate AI compute will be in space. This cost-efficiency alone will enable innovative companies to forge ahead in training their AI models and processing data at unprecedented speeds and scales, accelerating breakthroughs in our understanding of physics and invention of technologies to benefit humanity.

Many sources online are speculating that this new merged company will make the company’s initial public offering (IPO) now rumored for this summer even more sky high. I remain puzzled however why Musk would want to do it, and this merger today illustrates why. He controls both SpaceX and xAI completely, as both are privately owned. He didn’t need to convince government regulators of anything. Once the company is public, with publicly traded stock, that will change. He will no longer have such freedom of action.

A galaxy’s swirling dust lanes

12:07 pm

A galaxy with swirling dust lanes
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and enhanced to post here, was taken by the Hubble Space Telescope as part of follow-up observations of a now faded supernovae that occurred there two years earlier.

This was on purpose: the aim of the observations was to witness the aftereffects of the supernova and examine its surroundings, which can only be done once the intense light of the explosion is gone.

The galaxy itself, NGC 7722, is 187 million light years away, and is unusual in itself.

A “lenticular”, meaning “lens-shaped”, galaxy is a type that sits in between the more familiar spiral galaxies and elliptical galaxies. It is also less common than these — partly because when a galaxy has an ambiguous appearance, it can be hard to determine if it is actually a spiral, actually an elliptical galaxy, or something in between. Many of the known lenticular galaxies sport features of both spiral and elliptical galaxies. In this case, NGC 7722 lacks the defined arms of a spiral galaxy, while it has an extended, glowing halo and a bright bulge in the center similar to an elliptical galaxy. Unlike elliptical galaxies, it has a visible disc — concentric rings swirl around its bright nucleus. Its most prominent feature, however, is undoubtedly the long lanes of dark red dust coiling around the outer disc and halo.

The streak in the lower left is a very distant background galaxy, seen on edge.

Amazon buys ten more launches from SpaceX to place its Leo satellites in orbit

10:59 am

Amazon Leo logo

Hidden in Amazon’s submission last week to the FCC, requesting more time to launch its Leo internet constellation, was this tidbit:

Less than two years after the Commission granted its authorization, Amazon Leo announced the largest commercial launch procurements in history to deploy its initial constellation. It has since added to this launch capacity, and today has contracted for 102 launches across four providers: 18 launches on Arianespace’s Ariane 6, 24 launches on Blue Origin’s New Glenn, 38 launches on ULA’s Vulcan Centaur, 9 launches on ULA’s Atlas V, and 13 launches on SpaceX’s Falcon 9. [emphasis mine]

The highlighted phrases indicate the significant changes. In my initial post last week I was focused solely on whether the FCC would grant Amazon the time extension to get its constellation in orbit. At the moment it has only 180 satellites operating in orbit, and to meet its license requirement it must have 1,616 launched by July.

Thus, I didn’t look closely at these launch contract numbers. While the number of launches for Arianespace (18) and ULA (47) appears to match Amazon’s contract numbers from its original 2022 announcement, Blue Origin’s total has dropped by three launches, 27 to 24.

SpaceX in turn has gained another ten launches, on top of its original already completed 2023 three-launch contract. (In 2023, faced with a stockholder lawsuit for ignoring SpaceX’s Falcon 9, the only operational rocket among all of these at the time and by far the cheapest, Amazon’s management quickly signed SpaceX to that three-launch contract.)

The submission last week tells us that sometime recently Amazon signed SpaceX to a new contract for ten more launches. The numbers also suggest that the company took three launches away from Blue Origin’s New Glenn. Apparently, Amazon is not happy with Blue Origin’s launch pace, and signed SpaceX to help get more satellites in orbit. Without question, SpaceX will get these ten additional launches off faster than ULA, Arianespace, or Blue Origin combined. In fact, I bet it gets all ten done before the middle of this year, assuming Amazon can deliver it the satellites.

SpaceX launches 25 more Starlink satellites; uses 1st stage for 31st time

9:28 am

SpaceX this morning successfully placed another 25 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg in California.

The 1st stage (B1071) completed its 31st flight, landing on a drone ship in the Pacific. Though this number set no records, it moved that booster closer to catching the records for the most reused launch vehicle, presently held by the shuttle Discovery:

39 Discovery space shuttle
33 Atlantis space shuttle
32 Falcon 9 booster B1067
31 Falcon 9 booster B1071
29 Falcon 9 booster B1063
28 Falcon 9 booster B1069
28 Columbia space shuttle

Sources here and here.

The 2026 launch race:

14 SpaceX
6 China
2 Rocket Lab

This list is likely inaccurate, as Russia had a Soyuz-2 launch of a classified payload planned just prior to SpaceX’s launch, but as yet there been no confirmation of its success. SpaceX also has another launch schedule for this evening. I will include both when I update then.

Sunspot update: Maybe solar maximum isn’t over?

9:15 am

The uncertainty of science! It is time for another sunspot update. It is also time to note that once again the Sun appears to be confounding the predictions of NOAA’s solar science panel. Below is NOAA’s monthly graph of the sunspot activity on the Earth-facing hemisphere, updated by NOAA to include the activity in January but annotated with extra information by me to illustrate the larger scientific context.

Since April 2025 that science panel has been predicting that the solar maximum has passed and the Sun was beginning the ramp down to solar minimum, now expected to occur around 2031-32. And in the ten months since, sunspot activity has appeared to more or less track that prediction, as indicated by the purple/magenta curve line on the graph below.

It now appears that this prediction might very well have been premature.

SpaceX submits proposal to FCC for new constellation of one million satellites

3:03 pm

SpaceX yesterday submitted a proposal to Federal Communications Commission to build new satellite constellation made up of one million satellites designed as an orbiting data center.

In one 8-page document, SpaceX describes its proposed Orbital Data Center system. “To deliver the compute capacity required for large scale AI inference and data center applications serving billions of users globally, SpaceX aims to deploy a system of up to one million satellites to operate within narrow orbital shells spanning up to 50 km each (leaving sufficient room to deconflict against other systems with comparable ambitions),” the company says.

The same satellites would harness the sun’s energy, orbiting at “between 500 km and 2,000 km altitude and 30 degrees and sun-synchronous orbit inclinations,” the company adds. The orbiting data centers would also use “optical links,” or lasers, to connect with Starlink, using the existing satellite internet system to route traffic to users below.

“Orbital data centers are the most efficient way to meet the accelerating demand for AI computing power,” the filing adds in bold, pointing to the growing energy costs of AI data centers on Earth. The company is also betting it can launch the space-based data centers at a rapid clip using SpaceX’s more powerful Starship vehicle, which is also crucial to upgrading Starlink with next-generation satellites.

The FCC is likely not going to okay this submission, as written. It is clearly very preliminary, but appears to be consistent with SpaceX’s way of doing business. It sees an opportunity, and jumps in with full force. While others are working up their plans, SpaceX submits its first license proposal outlining the plan in very broad terms, thus getting there first.

And SpaceX is very well positioned to launch this constellation as promised. It has the rockets, and has proven itself capable of running a satellite constellation of vast size.

Axiom wins slot for next tourist mission to ISS

2:25 pm

NASA yesterday announced that it awarded the space station startup Axiom the next slot for a tourist mission to ISS.

NASA and Axiom Space have signed an order for the fifth private astronaut mission to the International Space Station, targeted to launch no earlier than January 2027 from the agency’s Kennedy Space Center in Florida.

…Axiom Mission 5 is expected to spend up to 14 days aboard the space station. A specific launch date will depend on overall spacecraft traffic at the orbital outpost and other planning considerations.

Both Axiom and the space station startup Vast had been bidding for the fifth and sixth tourist slots. That Axiom had already done this four times previously was probably NASA’s reasons for choosing it. The agency has not yet decided on who will get the sixth slot, targeting a mission likely in 2028. My bet is that it will give to Vast, because by then Vast’s own demo station Haven-1 will have launched and been visited, thus giving that company some of the experience Axiom already has.

Russia in discussions with Malaysian province about potential spaceport

1:49 pm

Proposed spaceports in Malaysia
Proposed spaceports in Malaysia

Officials from Glavcosmos, the commercial division of Russia’s Roscosmos space agency, have been holding meetings with officials from the Malaysian province of Sabah about building a spaceport there.

Glavkosmos said technical studies identify Sabah as the most suitable location in Southeast Asia for orbital launches, including low-earth and sun-synchronous orbits, due to its strategic geography and safe rocket stage drop zones. The proposed spaceport could create more than 2,000 high-income jobs and boost local supporting industries.

One year ago, in January 2025, the Sabah government announced it was holding similar discussions with the Ukraine. It seems either those talks fell through, or Russia decided to move in and block the Ukraine from making a deal.

A second Malaysian state, Pahang, is also planning a spaceport, working instead with China.

In all cases, it does appear for some reason Malaysia is not very interested in working with western nations.

Blue Origin shuts down New Shepard suborbital tourist flights

1:22 pm

Blue Origin yesterday announced it is “pausing” the suborbital tourist flights of its New Shepard spacecraft for no less than two years.

Blue Origin today announced it will pause its New Shepard flights and shift resources to further accelerate development of the company’s human lunar capabilities. The decision reflects Blue Origin’s commitment to the nation’s goal of returning to the Moon and establishing a permanent, sustained lunar presence.

Those “lunar capabilites” not only include its lunar landers, both manned and unmanned, but its New Glenn rocket, which it wants to sell to NASA to use for these missions. Both need more attention. In addition, it could be the company’s CEO, David Limp, wants to allocate more resources to the company’s Orbital Reef space station proposal, which has been sitting dead in the water for the past year-plus. All these projects have been very slow to get out of the starting gate, partly because of the very leisurely culture that Blue Origin’s previous CEO installed, and partly because the company has put out too many projects it is not focusing well on finishing.

There is also likely a third reason: New Shepard was not making a profit. While the company has been flying it quite regularly in recent months, it does not appear it could ever recover its costs. Moreover, I suspect the demand for these short suborbital tourist flights has diminished with advent of orbital tourism and the soon-to-arrive multiple commercial space stations.

Amazon asks FCC for time extension for launching its Leo constellation

11:22 am

Amazon yesterday submitted a request to the Federal Communications Commission to extend the July deadline on its license for its Leo internet satellite constellation, which presently requires it to have 1,616 satellites in orbit by that date.

At present Amazon has 181 satellites in orbit, all launched in the last ten months. At that pace there is no chance the company can meet its FCC requirement. From its FCC submission:

While Amazon Leo will meet the deadline for full deployment of its constellation established by its license and the Commission’s rules, launch delays will cause it to fall short of the interim milestone requirement to deploy half of its originally authorized constellation by July 30, 2026. The Commission’s rules provide for extension of such milestones where, as here, delay arises from unforeseeable circumstances beyond an operator’s control or overriding public interest considerations favor an extension.

Because it meets both criteria, Amazon Leo respectfully requests a 24-month extension of its 50% milestone to July 30, 2028, or alternatively, a waiver of this interim requirement.

In its submission Amazon claims the delay is entirely the fault of the rocket companies it was relying on to launch the satellites, but that is a bogus claim. It initially choose to depend almost entirely on three new rockets (Blue Origin’s New Glenn, ULA’s Vulcan, and Arianespace’s Ariane-6), all of which had not launched and were still under development. To expect these to launch on time was absurd.

Furthermore, its ULA contract also called for launches using company’s already operational Atlas-5 rocket, which Amazon claims were delayed because of “unexpected anomalies and delays caused by issues with its vehicle fairings and solid rocket boosters.” I don’t buy it, and suspect the real cause was that Amazon was unable to produce the satellites on time.

Faced with these delays and a stockholder lawsuit, Amazon subsequently signed SpaceX to do three launches, which that company did quickly, in less than four months. If Amazon had truly wanted to get its Leo satellites in orbit on time, it would have given SpaceX more launches and gotten it done.

Nonetheless, it is likely the FCC will agree to Amazon’s extension request. The company has now shown it is committed to the process and intends to get its constellation in orbit. It is not sitting on its license doing nothing. I would not be surprised however if the FCC imposes some new requirements in an effort to force Amazon to launch more satellites more quickly.

Comet K1/Atlas has broken apart, not interstellar Comet 3I/Atlas

10:37 am

the end of Comet K1/Atlas

CORRECTION: The image to the right is not that of interstellar Comet 3I/Atlas, as I reported earlier today. I misread the Gemini Telescope release. This is comet K1/Atlas, another comet from our own solar system that made its close approach to the Sun in October, when it broke up.

The the latest image from the Gemini North Telescope in Hawaii shows at least four sections slowly drifting apart.

The picture to the right, cropped to post here, was taken on December 6, 2025. Gemini’s previous image, taken in November 11th, shows about the same number of objects, but clustered much more closely together.

It appears that as the comet made its closest approach, the stress was too great. This is not surprising, as it happens to many comets that get too close to the Sun.

Sorry for the error and hat tip to reader Tom Laskowski for letting me know. I need to look at the names of comets named after the ATLAS telescope, as they are very similar and most are NOT interstellar comet 3I/Atlas.

China launches Algerian satellite

10:23 am

China today successfully placed an Algerian “remote sensing” satellite into orbit, its Long March 2C rocket lifting off from its Jiuquan spaceport in northwest China.

No word on where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China. China’s state-run press also said little about the satellite, other than claiming it would be used for “land planning and disaster prevention and mitigation.” This however doesn’t match what “remote sensing” satellites usually do, which is military surveillance.

The 2026 launch race:

13 SpaceX
6 China
2 Rocket Lab

Rumors: Musk is considering merging SpaceX with xAI and Tesla

1:56 pm

According to a bunch of unconfirmed stories today from different news outlets, Elon Musk is considering merging SpaceX with xAI and Tesla as part of the initial public offering (IPO) of SpaceX that the company is contemplating for sometime this summer.

Reuters reports that Musk wants to merge xAI — his very valuable AI company that has already merged with the company that used to be called Twitter — into SpaceX, his very valuable rocket company. And Bloomberg reports that SpaceX is also considering a merger with Tesla, citing people familiar with the matter.

The SpaceX-xAI tie-up could help Musk build data centers in space. “The combination would bring Musk’s rockets, Starlink satellites, the X social media platform and ​Grok AI chatbot under one roof,” the Reuters report says. Then again, Reuters also says it doesn’t know several key details about the theoretical deal, including “its ‌primary rationale.”

None of this is confirmed, but Musk has not denied it either. If so, this IPO would be the largest ever in the history of the stock markets, by many magnitudes. As noted at the link, xAI is raising gigantic amounts of capital. SpaceX in turn is expected to do even better in its IPO, as a single entity. Tesla is in far less demand, but this merger could be a way to reshape that company to give it a better future. It has already said it is beginning the transition from electronic cars to robots and other autonomous machines.

Whether such a merger will help SpaceX or Musk in his goal of building a Mars colony remains decidedly uncertain. A publicly traded stock company does not have the freedom of action that SpaceX now has as privately owned company.

Russian defunct military satellite breaks up in graveyard orbit

1:42 pm

A Russian defunct military geosynchronous satellite that was launched in 2014 and spent a decade spying on other geosynchronous satellites only to be moved to a graveyard orbit in 2025 when its fuel ran out apparently broke apart earlier today.

The Swiss company S2A systems, which specializes in tracking orbital objects, captured the moment the spacecraft began disintegrating. I have embedded that footage below, though it really is far less exciting than it sounds.

The debris poses a very small risk to other geosynchronous satellites, which orbit at about 22,000 miles elevation where there is too little atmosphere to decay orbits. The graveyard orbit is several hundred miles higher.

FAA moves forward on its environmental assessment of SpaceX’s proposal to launch Starship/Superheavy from Kennedy Space Center

12:01 pm

Proposed Starship/Superheavy launchsites at Kennedy and Cape Canaveral
Proposed Starship/Superheavy launchsites at
Kennedy (LC-39A) and Cape Canaveral (SLC-37)

While NASA has already determined that Starship/Superheavy launches from the Kennedy Space Center in Florida will have no significant impact on the environment, the FAA has not yet completed its own environmental impact statement.

Last week it released a preliminary summary [pdf] of its impact statement, revealing that it has reduced its final options to either approving SpaceX’s request to do as many as 44 launches per year, or to reject any changes — the “no action alternative” — which would block all Starship/Superheavy launches at Kennedy.

The overall tone of this summary suggests strongly that the FAA is almost certainly going to approve SpaceX’s request, allowing as many as 44 launches per year from launchpad LC-39A, as shown on the map to the right. As it notes in describing the “no action alternative”:

SpaceX would not launch Starship-Super Heavy from LC-39A. NASA would not develop, implement, or approve agreements with SpaceX associated with Starship-Super Heavy operations at LC-39A. The No Action Alternative would not meet the purpose and need. [emphasis mine]

In other words, rejecting SpaceX’s request would not fulfill the FAA’s obligation to serve the public. It would also not fulfill the FAA’s obligation to serve a fellow government agency, NASA, which has already approved this SpaceX request in a 2019 environmental assessment.

It appears a final decision by the FAA is imminent. A nice summary of this FAA document can be found here, which notes that if approved, it will give SpaceX license approval to launch Starship/Superheavy as much as 146 times per year, from its launchpads at Boca Chica, Kennedy, and Cape Canaveral. Note too that this FAA assessment is independent of the Air Force’s environment assessment, which has already approved 76 launches per year at the SLC-37 launchpad.
