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

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.

Russia still using black market Starlink terminals on its drones

In its war with the Ukraine, it appears Russia is still managing to obtain black market Starlink mini-terminals for use on its drones, despite an effort since 2024 to block access.

According to Defense Express on November 30, imagery has emerged showing what appears to be a Russian “Molniya”-type drone fitted with a mini-Starlink unit, reportedly observed near the Pokrovsk sector in eastern Ukraine. The configuration—an off-the-shelf satellite internet terminal strapped to a drone—suggests improvised but functional integration, consistent with past sightings. The drone’s design and power unit indicate it is of Russian origin, likely a variation of the Molniya unmanned aerial vehicle, which is known for its low-cost, modular construction.

The use of Starlink terminals on Russian drones was first publicly reported in early 2024. Since then, Ukrainian forces have documented multiple instances of their use, including on Shahed-136 drones and larger UAVs such as the RD-8 “mothership” drone, which is reportedly capable of controlling other loitering munitions using satellite connectivity. The main concern raised by Ukrainian defense observers is that Starlink-based control enables extended-range communications, allowing Russian drones to conduct reconnaissance or strike missions far from ground-based operators.

SpaceX has made no comment on this issue. According to the article, the Ukraine is “exploring alternative European satellite providers in response, seeking more secure and controllable communications infrastructure for military operations.” While switching to another satellite provider might allow the Ukraine to shut Starlink down and prevent the Russians from using it within its territory, doing so would likely do more harm to the Ukraine’s military effort than Russia’s. There isn’t really any other service comparable at this time. And when Amazon’s Leo system comes on line it will face the same black market issues. I doubt it will have any more success than SpaceX in preventing Russia from obtaining its terminals.

Overall this issue is probably not a serious one militarily, however. Russia is not likely capable of obtaining enough black market terminals to make any significant difference on the battlefield.

This story however highlights a positive aspect of these new constellations. Just as Russia can’t be prevented from obtaining black market terminals, neither can the oppressed citizens in totalitarian nations like Russia and China be blocked as well. These constellations as designed act to defeat the censorship and information control of such nations, a very good thing.

South Korean rocket startup Innospace announces date for inaugural launch

The South Korean rocket startup Innospace late last week announced that it has delayed the date for the first launch of its Hanbit-Nano rocket a few days in order to correct a “minor anomaly” during testing in Brazil.

During the avionics integration test, INNOSPACE performed a detailed analysis of a minor signal anomaly observed in a specific segment of the test and confirmed the tolerance range of the integration profile affected by flight-environment variations. To further validate the findings, the company carried out a second test using a Brazilian Air Force aircraft under conditions closely replicating the actual flight environment, allowing for a comprehensive review of response characteristics and signal stability across all integration items.

The launch was previously scheduled for a launch window from November 22nd to December 17th, taking place from Brazil’s long unused Alcantara spaceport on its northeast coast. The new window now runs from
December 16th to December 22nd. The launch itself is now scheduled for December 17th.

If this launch is successful, South Korea will have leapfrogged past India, Japan, and Australia to be the first Asian country to have a private company successfully launch a rocket.

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.

New Australian rocket startup completes suborbital launch

Proposed Australian spaceports
Australian spaceports: operating (red dot) and proposed (red “X”)
Click for original image.

A new Australian rocket startup, AtSpace, announced earlier this week it had successfully launched a test suborbital rocket from the commercial spaceport Southern Launch on the south coast of Australia.

At 09:22 AM [on November 27th], the 12.2m tall vehicle rocketed from Southern Launch’s Koonibba Test Range, performed perfectly and flew close to the target altitude of 80km. The four-and-a-half-minute flight validated AtSpace’s hybrid propulsion technology before safely returning to Earth as planned.

According to the press release, the company was able to recover the rocket afterward.

The company’s website says it was founded in 2021, and plans an orbital rocket dubbed Kestral, using hybrid fuels. No target dates for a first launch however are provided.

AtSpace is Australia’s second rocket startup to launch, following Gilmour Space’s failed launch attempt from its own Bowen spaceport on the east coast of Australia. Gilmour hopes to try again next year.

China launches classified payload into orbit

China early today successfully placed a classified satellite into orbit, its Long March 7A rocket lifting off from its coastal Wenchang spaceport in southern China.

Video of the launch can be seen here.

China’s state-run press provided no information about the satellite or payload.

China's communists to its citizens
China’s communists to its citizens “Nice business you got here.
Shame if something happened to it.”

In related news, that state-run press made official what had been rumored in late October, that the government has now formed a special agency to supervise the pseudo-companies in its faux commercial rocket industry.

In other words, the government has decided the little freedom it gave these pseudo-companies was too much. It is now going to coordinate their efforts from above, and do so much more tightly. I suspect this decision was prompted by the success of some of these companies — taking advantage of that small measure of freedom. The government’s has gotten some new rockets and satellite constellations. Now it can step in and take over, like the mobsters communist governments are.

Ginger Rogers & Fred Astaire – Swing Time

An evening pause: From the 1936 film of the same name. Fred improvises to save Ginger’s job as a dance teacher. Watch how Rogers’ impression of him and her interaction during the dance evolves so naturally. I have always found her to be not only a great dancer, able to keep up with Astaire (the king of all dance), but also a marvelous actress.

Note too how this is not the gymnastics of modern dance, which is often only one small step above a Jane Fonda exercise video, but an amazingly nuanced and choreographed sequence of complex steps and moves, set to American pop music but with graceful classical ballet in mind.

SpaceX launches another Transporter mission, including dozens of smallsats

SpaceX today successfully completed its fifteenth Transporter mission of smallsats, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.

The two major customers for this mission were Planet Lab, placing 36 satellites for its imagery constellation, and Exolaunch, which acts as a launch manager for smallsat companies. It placed 58 payloads in orbit for many various companies. Another launch manager company, SEOPS, launched 7 payloads, while the European aerospace company OHB launched 8. Among the other payloads was Varda’s fifth re-usable capsule.

The rocket’s two fairings completed their fourth and fifth flights respectively. The first stage (B1071) completed its 30th flight, landing on a drone ship in the Pacific. With this launch this booster become the second SpaceX first stage to achieve at least thirty flights. As the rankings for the most reused launch vehicles below show, SpaceX now has four boosters close to becoming the most reused rockets ever.

39 Discovery space shuttle

ESA’s member nations approve a major budget increase

The European Space Agency

At the council meeting of the European Space Agency’s (ESA) member nations taking place this week in Bremen, Germany, the council approved a major 32% budget increase for the agency over the next three years.

The largest contributions in the history of the European Space Agency, €22.1 bn, have been approved at its Council meeting at Ministerial level in Bremen, Germany.

Ministers and high-level representatives from the 23 Member States, Associate Members and Cooperating States confirmed support for key science, exploration and technology programmes alongside a significant increase in the budget of space applications – Earth observation, navigation and telecommunications. These three elements are also fundamental to the European Resilience from Space initiative, a joint response to critical space needs in security and resilience.

“This is a great success for Europe, and a really important moment for our autonomy and leadership in science and innovation. I’m grateful for the hard work and careful thought that has gone into the delivery of the new subscriptions from the Member States, amounting to a 32% increase, or 17% increase if corrected for inflation, on ESA’s 2022 Ministerial Council,” said ESA Director General Josef Aschbacher.

How ESA will use this money however remains somewhat unclear, based on a reading of the various resolutions released in connection with this announcement. As is typical for ESA, the language of every document is vague, byzantine, and jargon-filled, making it difficult to determine exactly what it plans to do. Overall it appears the agency will continue most of the various projects it has already started, and do them in the same manner it has always done them, taking years if not decades to bring them to fruition (if ever). It also appears the agency will devote a portion of this money to create new “centers” in Norway and Poland, which as far as I can tell are simply designed to provide pork jobs for those nations and ESA.

The resolutions also placed as the agency’s number one goal not space exploration but “protect[ing] our planet and climate” (see this pdf), a focus that seems off the mark at a very base level. While I could find nothing specifically approving the odious space law that attempted to impose European law globally (and has been vigorously opposed by the U.S.), the language in this document suggests the council still heartily wants to approve that law, and if it doesn’t do so in total it will do so incrementally, bit by bit, in the next few years.

The most hopeful item among these resolutions was the €4.4 billion the council reserved for space transportation, with the money to be used to pay for upgrades to both the Ariane-6 and Vega-C rockets and the facilities in French Guiana, as well as expand ESA’s program encouraging the new rocket startups from Germany, Spain, and France. If ESA uses this money wisely — mostly for the latter item — it will do much to create for itself a competitive launch industry, something it presently does not have.

It will take a bit of time to see how these decisions play out. It remains very unclear at this moment if Europe is choosing the Soviet or the capitalism model for its future in space.

Russia’s only manned launchpad damaged badly during yesterday’s launch

During the successful Soyuz-2 rocket launch yesterday carrying three astronauts to ISS, the “mobile service platform” used to transport the rockets to the pad (similar to the strongback used by Falcon 9 rockets), collapsed into the flame trench below it.

According to preliminary estimates, repairs of the service platform, known as 8U216, could take up to two years and it was not immediately clear whether some kind of makeshift arrangement would be possible to support multiple cargo and crew launches to the ISS in the interim. There was some possibility that duplicate hardware could be borrowed from the mothballed Site 1 in Baikonur or from similar facilities at other launch sites. There were four Soyuz pads in Plesetsk at one point, including an unused existing structure at Site 16, also one pad operated in Vostochny.

The Plesetsk pads however are at higher latitude, and any spacecraft launched from there would have difficulty rendezvousing with ISS.

It appears that the failure was the result of inadequate maintenance at Baikonur, or another example of the poor quality control that has plagued Russia’s aerospace industry for the past two decades.

Unofficially, violations of operational procedures, stemming from increasingly scarce maintenance of the facility in the past few years, were blamed for the collapse of the structure. According to another rumor, the mobile platform was not properly secured in its underground shelter before launch, which let the blast wave from the rocket exhaust pull it off its guide rails into the flame trench.

This wasn’t the only failure for Russia in the past day. At its now rarely used Yasny military launch site witnesses reported a rocket exploding after launch yesterday. Though images are available confirming something went wrong shortly after lift-off, no other information has been released by Russia.

Russia planned to launch a Progress freighter to ISS in late December. That launch will now likely be delayed. In fact, the pad damage threatens the entire supply stream to ISS, requiring possibly additional American cargo missions (which almost certainly SpaceX can provide).

Thanksgiving repost: Miracle on 34th Street

An evening pause: This was posted in 2023. Time to repost.

Original text:
—————————
This movie used to be a tradition for television on Thanksgiving. At that time the holiday was well linked with the then joyous and relatively Christian Macy’s Day Parade (now warped into a queer agenda demonstration). [Editor: an agenda that thank god appears to be on the run.]

I think it makes for a good opening to the holiday season.
