An evening pause: I posted this Judd Clark suggestion previously in December 2023, but Judd sent it to me again and I agree, it deserves a reprise. It reminds us that despite all the craziness that has happened in the world in the past half century, children still see wonderful things we have forgotten exist.

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.
"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

Cool image time! The picture to the right, rotated, cropped, and reduced to post here, was taken by the Hubble Space Telescope on February 8, 2025, and shows what scientists believe is the largest protoplanetary disk so far measured.
Located roughly 1,000 light-years from Earth, IRAS 23077+6707, nicknamed “Dracula’s Chivito,” spans nearly 400 billion miles — 40 times the diameter of our solar system to the outer edge of the Kuiper Belt of cometary bodies. The disk obscures the young star within it, which scientists believe may be either a hot, massive star, or a pair of stars. And the enormous disk is not only the largest known planet-forming disk; it’s also shaping up to be one of the most unusual.
…The impressive height of these features wasn’t the only thing that captured the attention of scientists. The new images revealed that vertically imposing filament-like features appear on just one side of the disk, while the other side appears to have a sharp edge and no visible filaments. This peculiar, lopsided structure suggests that dynamic processes, like the recent infall of dust and gas, or interactions with its surroundings, are shaping the disk.
You can read the peer-reviewed paper here [pdf]. The structure of this system has left them with more questions than answers. They can’t see the central star due to the dust. They don’t know if any planets exist as yet in the system. They don’t really understand the structural details that they can see.
According to a tweet by SpaceX yesterday, Starlink now has nine million active customers in 155 countries worldwide.
These numbers tell us the company is now getting more than a billion dollars per month in revenues, based on what it charges for its various plans. What make the numbers even more startling is how fast they are growing.
In a similar post from November 5, SpaceX said Starlink had 8 million customers, meaning that its customer base has expanded at a rate of more than 20,000 per day since that date.
At more than billion dollars per month, SpaceX essentially has about half the annual revenue of NASA, which it can use far more efficiently. And those numbers will only increase in the coming years, as the company opens up new markets worldwide and begins launching its upgraded Starlink satellites with Starship.
It still seems to me puzzling why, with these numbers, Musk is considering making the company public this coming summer. Though that move would bring in a gigantic amount of new investment capital from the stock sale, it would also subject the company to serious government regulation as a publicly-traded company. The Starlink revenue can only grow. Why add government interference when you can live without it?

In releasing today the preliminary results of its investigation into the failure on December 21, 2025 of the upper stage of its H3 rocket, Japan’s space agency pinned the likely cause on the rocket’s fairings.
Japan Aerospace Exploration Agency officials told a science ministry panel on Dec. 23 they suspect an abnormal separation of the rocket’s payload fairing—a protective nose cone shield—caused a critical drop in pressure in the second-stage engine’s hydrogen tank.
Engineers think the fairing might have hit the rocket at separation, damaging the tank.
Japan at present has no way to launch payloads. It has no operating independent commercial rocket companies, and its JAXA-owned H3 and Epsilon-S rockets have had repeated problems. The H3 failed on its first launch in 2023, causing a year-long delay, and Epsilon-S still in limbo because of repeated failures during development.
The Sun is about going to cause a month-long break in communications with Curiosity and Perseverance, the two rovers on Mars.
This communications pause occurs every two years, when the orbits of Earth and Mars align with the Sun in between.
This holiday season coincides with conjunction — every two years, because of their different orbits, Earth and Mars are obstructed from one another by the Sun; this one will last from Dec. 27 to Jan. 20. We do not like to send commands through the Sun in case they get scrambled, so we have been finishing up a few last scientific observations before preparing Curiosity for its quiet conjunction break.
This is not a unique situation. Both rovers have gone through conjunction several times previously. The science teams will place the rovers in secure positions to hold them over during the break.
As for the orbiters circling Mars, it isn’t clear how much their operations will be impacted. The update at the link above makes no mention of them, and my memory says communications with them is less hampered, though reduced somewhat.

"Leaving Earth is one of the best and certainly the most comprehensive summary of our drive into space that I have ever read. It will be invaluable to future scholars because it will tell them how the next chapter of human history opened." -- Arthur C. Clarke
China’s new Long March 12A reusable rocket completed its first launch today (December 23 in China), lifting off from the Jiuquan space spaceport in northwest China. The attempt to softly land the first stage vertically at a landing pad down range however failed.
According to one report, the rocket’s upper stage reached orbit, but this remains unconfirmed. A Google-translation of this Chinese state-run report confirmed the failure of the first stage:
The rocket lifted off successfully after ignition, and its flight appeared normal during the visual observation phase. However, reports from the recovery site indicated an anomaly during the first stage’s re-entry, resulting in a “mushroom cloud” formation, and the successful recovery of the first stage was not achieved.
Several Chinese outlets showed the same image of that cloud. This is the second unsuccessful attempt by China this month to land a first stage, the first being the December 2nd attempt by the Chinese pseudo-company Landspace’s Zhuque-3 rocket. The Long March 12A is built by the government, so there is no make-believe company involved.
UPDATE: China’s state-run press has confirmed the upper stage reached orbit.
The leaders in the 2025 launch race:
168 SpaceX
86 China (a new record)
18 Rocket Lab
15 Russia
SpaceX still leads the rest of the world in successful launches, 168 to 143.
Though details are not yet available, the first launch by South Korean rocket startup Innospace of its Hanbit-Nano rocket failed less than 2 minutes after liftoff from Brazil’s long unused Alcantera spaceport. The failure occurred sometime after the rocket passed through max-q, the moment when the aerodynamic pressure of the atmosphere and the speed of the rocket stresses the rocket the most.
The live stream provided no details, other than to say “we experienced an anomaly during the flight.” No other details have yet been released.
The image to the right is a screen capture of the rocket lifting off the pad, less than a few seconds after T-0. Though the rocket appeared to move upward in a smooth controlled flight, soon thereafter it became impossible to see anything but the bright engine flame at its base. Either the flames were so bright it overexposed the live stream, or the fire was spreading beyond the nozzles. At the moment however we know nothing about what happened.
An evening pause: One of the most beautiful sections of Handel’s masterpiece, often missed because it is quiet and gentle in tone.
According a brief announcement today from Robert Lightfoot (ULA Lockheed Martin Board Chair) and Kay Sears (ULA Boeing Board Chair), Tory Bruno has resigned as CEO and president of United Launch Alliance, effective immediately.
After nearly 12 years leading United Launch Alliance (ULA), current ULA President and CEO Tory Bruno has resigned to pursue another opportunity.
We are grateful for Tory’s service to ULA and the country, and we thank him for his leadership.
Effective immediately, John Elbon is named as the Interim CEO. We have the greatest confidence in John to continue strengthening ULA’s momentum while the board proceeds with finding the next leader of ULA. Together with Mark Peller, the new COO, John’s career in aerospace and his launch expertise is an asset for ULA and its customers, especially for achieving key upcoming Vulcan milestones.
No further information was provided.
The timing is intriguing, as after a decade of effort, Bruno was about to get ULA’s new Vulcan rocket launching on a regular basis. I could speculate, but at the moment there isn’t enough information to make even a good guess.
Hat tip to reader Gary.

That landing changed rocketry forever. As I wrote the next day:
Despite living in a time when freedom is denigrated, when free speech is squelched, and when oppressive regulation and government control is the answer to every problem, the enduring spirit of the human soul still pushed through to do an amazing thing.
SpaceX’s success is only the beginning. The ability to reuse the engines and first stage will allow them to lower their launch costs significantly, meaning that access to space will now be possible for hundreds if not thousands of new entrepeneurs who previously had ideas about developing the resources of the solar system but could not achieve them because the launch costs were too high.
This is what the Christmas season stands for.
The New Testament words celebrating the birth of Jesus are clear and bright, and are repeated by everyone in these weeks before the holiday: “Glory to God in the highest, and on earth peace, good will toward men.”
The colloquial phrase people normally say this time of year is usually “Peace on Earth and good will toward men!”, with the hope that both will come to all.
It appears unfortunately that the idea of “good will” is vanishing from American society, and maybe for all of western civilization. Good will means you treat all persons with respect, even if you disagree with them. You also hope that everyone achieves the best they can in their personal lives, even your enemies. You don’t wish harm on others, only oppose anyone from doing harm to others.
Such good will once dominated American society. Just think of the 1946 film It’s a Wonderful Life! to get a taste of that American culture. In politics, there was often fierce debate, but after the Civil War especially the culture decided it was better to talk things out with good will to all then to grab guns and kill each other.
And most of all, during each year’s Christmas season the desire to promote good will was everywhere, in everyone’s hearts and minds.
This ideal now appears to be vanishing. On the left that vanishing began with the election of Donald Trump in 2016, and has accelerated since. You cannot have a reasonable or rational discussion with practically anyone on the left about Trump. He is the devil incarnate to them, and anyone who even expresses the slightest positive thought about him must be blackballed, slandered, and even killed.
Think I am exaggerating? The widow of Charlie Kirk doesn’t think so. Neither does Donald Trump, who survived two assassination attempts. Nor does someone like Elon Musk, who now readily admits he can no longer appear in public out of fear of violence because of his support of Trump in the 2024 election.
A more benign but equally ugly example of this lack of good will occurred just last week — in the midst of this year’s Christmas season — and the anger and hate didn’t just come from the left. Watch the vile behavior of this leftist woman in a Walmart when she saw an senior citizen and Target worker wearing a Charlie Kirk “Freedom” t-shirt (warning: her language is decidedly obscene):
