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.

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. If you buy it from 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

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.

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.

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.

General Electric – Conquest of the Cascades

6:01 pm

An evening pause: According to this website, this documentary was “made by General Electric between 1928 and 1929 to commemorate the completion of this monumental [8-mile-long] tunnel which took 1800 workers and three years to construct.”

Three years! Today that’s how long it would take just to get the environmental assessment written and approved.

Hat tip Blair Ivey.

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.
