China launches nine more satellites in Guowang constellation

Last night China successfully placed nine more satellites for the Guowang (or Satnet) internet-of-things constellation, its Long March 8A rocket lifting off from its Wenchang coastal spaceport, The constellation now has 128 satellites in orbit out of a planned 13,000. Though the rocket’s lower stages all fell in the ocean, some landed within the Philippines, once again requiring that government to warn its citizens to avoid the drop zones.

China’s last night also scrubbed a launch of its solid-fueled Smart Dragon-3 (also Jielong-3) rocket, set to lift off from a launch platform off the coast of northeastern China. The launch was rescheduled for December 28th. China also had a Long March 3B launched scheduled for this morning, but no news about that launch as yet been published.

The leaders in the 2025 launch race:

168 SpaceX
87 China (a new record)
18 Rocket Lab
16 Russia

SpaceX still leads the rest of the world in successful launches, 168 to 146.

Former ULA CEO Tory Bruno now working for Blue Origin

In a tweet on X, Blue Origin today announced that former ULA CEO Tory Bruno is now working for them, acting as president for its “newly formed National Security Group.”

Blue Origin’s CEO, David Limp, quickly chimed in with his own tweet, endorsing the hire.

My guess is that Limp felt Blue Origin needed someone with experience dealing with the military, and Bruno brings that capability, having managed ULA’s military launch contracts for years. It also means Blue Origin is very serious about grabbing a larger market share of those launches once its New Glenn rocket begins launching regularly.

I also wonder if Bruno grew tired of the culture at ULA, which has appeared resistant to building reusable rockets. Bruno sold Vulcan initially with the idea of quickly upgrading it to recover its engines for reuse, but by all signs the company has been very unenthusiastic about the idea. (The idea itself might not be viable, but overall ULA has shown no interest in developing a reusable rocket of any sort.) Bruno might have decided he’d rather work with a company enthused by reusability, especially as this is the future. Once ULA completes its large Amazon Leo launch contract it faces a bleak future, with many newer cheaper reusable rockets coming on line.

It could also be that Bruno was made an offer he couldn’t refuse. Money is always a powerful incentive.

Japanese bank invests in Starlab

The consortium building the Starlab space station today announced that the Sumitomo Mitsui Trust Bank of Japan has invested in the project.

Through this investment, SuMi TRUST Bank will support Starlab’s efforts to develop and commercialize space station technologies, while exploring opportunities for collaboration that contribute to the advancement of space-related industries and broader industrial development in Japan and globally.

The press release provided no other information, other than this boilerplate PR jargon. The amount invested was not mentioned.

Regardless, the investment tells us two things: First, Starlab has now raised more than $400 million in investment capital, and appears in a solid position to begin work on its large single module station to be launched on Starship.

Second, the investment in this American-based space project by this Japanese bank speaks volumes about the sad state of Japan’s own commercial space industry. Other than the lunar lander Ispace, Japan has seen little success from any other major rocket startups. One rocket startup, Interstellar, has obtained some investment capital, but the development of its rocket seemingly stopped for the past five years. Another, Space One, has had one launch failure. And though Honda has completed a successful vertical take-off and landing of a small rocket prototype, it doesn’t expect to attempt an orbital launch until 2030.

Meanwhile, the two rockets owned by Japan’s space agency JAXA, the H3 and Epsilon, are grounded because of launch failures.

It appears this bank believes it is more likely to earn profits from this American project than from these other Japanese space efforts.

Recovering Maven appears increasingly dim

According to a NASA update late yesterday, engineers have still not been able to recover the Maven Mars orbiter since all communications ceased suddenly on December 6, and are now facing a month-long period when the Sun will block all communications with Mars entirely.

The MAVEN team also continues to analyze tracking data fragments recovered from a Dec. 6 radio science campaign. This information is being used to create a timeline of possible events and identify likely root cause of the issue. As part of that effort, on Dec. 16 and 20, NASA’s Curiosity team used the rover’s Mastcam instrument in an attempt to image MAVEN’s reference orbit, but MAVEN was not detected. Additional analysis will continue, but planned monitoring will be affected by the upcoming solar conjunction.

Mars solar conjunction – a period when Mars and Earth are on opposite sides of the Sun – begins Monday, Dec. 29, and NASA will not have contact with any Mars missions until Friday, Jan. 16. Once the solar conjunction window is over, NASA plans to resume its efforts to reestablish communications with MAVEN.

That December 6th tracking data had suggested the spacecraft was tumbling. Though NASA management has not yet given up hope, the longer the spacecraft remains out of touch and in an uncontrolled state, the less chance there will be for it to survive. Batteries will drain, equipment will freeze, and the spacecraft will die. Right now, that appears to be its fate.

India launches AST SpaceMobile’s sixth Bluebird satellite

India’s space agency ISRO today (December 24 in India) successfully launched AST SpaceMobile’s sixth Bluebird satellite into orbit, its Bahubali rocket (LVM3) lifting off from its Sriharikota spaceport on India’s eastern coast.

This Bluebird is an upgrade from the first five satellites, providing ten times the bandwidth. The constellation acts as satellite cell towers for smart phones. These Bluebird satellites have been the largest in size ever launched, and this satellite will break their previous records. It is also the heaviest satellite India’s Bahubali rocket has ever put in orbit, on its sixth launch.

For India, this is its fourth launch in 2025. The leaders in the 2025 launch race:

168 SpaceX
86 China
18 Rocket Lab
15 Russia

SpaceX still leads the rest of the world in successful launches, 168 to 144.

Hubble images gigantic protoplanetary disk

Largest known protoplanetary disk
Click for original image.

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.

Starlink added a million new customers in just the past month

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?

JAXA identifies cause of H3 rocket failure

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.

No contact with Mars’ rovers for the next month

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.

China’s Long March 12A launches but fails to land the first stage

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.
