China launches Earth mapping satellite

8:20 am

China yesterday successfully placed what it called a “geographic mapping” satellite, its Long March 4B rocket lifting off from its Jiuquan spaceport in northwest China.

Its state-run press provided no additional information about the satellite, nor did it provide any information about where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China.

The leaders in the 2025 launch race:

168 SpaceX
89 China (a new record)
18 Rocket Lab
17 Russia

SpaceX still leads the rest of the world in successful launches, 168 to 149.

The headwaters of an ancient Martian channel

glacial debris in canyon floor

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on October 24, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this simply as “irregular terrain.” It is far more than that. We are looking at a three-mile-wide shallow canyon, with what appear to be eroding glacial features on the canyon floor.

The location is at 35 degrees north latitude, so finding glacial features here is entirely unsurprising, especially because this location is the southern edge of the 2,000-mile-long mid-latitude strip in Mar’ northern hemisphere I label glacier country, because almost every picture shows such glacial features.

In this case, the channel also suggests a much more complex geological history, that could involve flowing water though flowing glaciers are increasingly becoming an alternative explanation.

SpaceX pulls Starlink service from Papua New Guinea

9:23 am

SpaceX has now withdrawn the Starlink services it informally had provided customers in Papua New Guinea after a volcano eruption in 2021 due to regulatory demands by the government there.

It’s been two and a half years since a volcano eruption tore apart Tonga’s underwater internet cables, and a sympathetic Kiwi MP pleaded to Elon Musk for help on their behalf. Musk, CEO of SpaceX, would answer Shane Reti’s call, offering his Starlink technology in aid of their reconnection to the world.

Starlink’s Pacific debut came with limited trials in American-owned Guam and the Northern Marianas, followed by the Cooks in April 2021. But for the wider Pacific community, its deployment in Tonga captured hearts and minds. The service, provided by a special satellite network, has been hailed as “transformational” in numerous island nations, broadening internet coverage to remote areas, some for the first time.

That is, unless, you’re in Papua New Guinea. Starlink’s attempts to gain licensing in PNG have been tied up since December 2023, with the Ombudsman Commission challenging the government over Starlink’s reliability. The Commission blocked licensing efforts in February 2024, and have argued that existing regulations may not be adequate to manage potential risks to public interest and safety.

In-fighting within Papua New Guinea’s government continues to block Starlink license approval, so it appears SpaceX has decided the best way to get a positive decision is to walk away, hoping the ensuing pressure from its customers might force action from the government.

ESA cancels call for commercial cargo services to ISS

9:14 am

European Space Agency logo

In what might be a larger decision by the European Space Agency (ESA) to pull back from support to ISS, the agency has cancelled a call for proposals that asked private commercial startups to provide cargo to ISS.

On 3 October, ESA published a call for proposals under its CSOC Cargo Commercially Procured Offset (3CPO) initiative, seeking commercial transport services to the ISS to deliver between 4,900 and 5,000 kilograms of pressurised cargo to the orbiting laboratory. According to the call, the mission was intended to act as a “strategic offset’ to secure flight opportunities for ESA astronauts. It did, however, stipulate that the prospective procurement would only proceed if member states agreed to fund the initiative at the agency’s Ministerial Council meeting on 26 and 27 November 2025.

Following the late November meeting, ESA announced that member states had “agreed to implement short-term actions to guarantee European astronauts’ access to the International Space Station until its planned end of exploitation in 2030.” While this initially appeared to signal a favourable decision on the 3CPO initiative, the agency formally cancelled the call on 17 December, citing “the implementation of programmatic adjustments.”

What makes me speculate that this decision is part of a larger strategy to pull back from ISS is based on other statements by ESA officials cited in the article. It appears ESA is also delaying the mission of one astronaut to ISS that had originally been planned for ’26, possibly by as much as two years.

Though that official said ESA had fully funded its commitments to ISS at its recently concluded ministerial council meetings, both of the above decisions suggest it is shifting its support elsewhere. It could very well be that ESA is beginning the process of transferring its support from ISS to the new commercial private stations, most especially Starlab, which it already has signed a partnership agreement. By delaying funding to ISS, it reserves that money for later use at the new stations.

Another American orbital capsule company turns to Australia for a landing spot

The American orbital capsule company Lux Aeterna has now signed a deal with the Australian spaceport startup Southern Launch to allow its capsules to land at its Koonibba Test Range in southern Australia.

Under the agreement, two Lux Aeterna Delphi satellites will return to the Koonibba Test Range with Southern Launch. The first mission is targeted to return in 2027.

Lux Aeterna, based in Denver, Colorado, USA, is developing a reusable satellite platform designed to operate in Low Earth Orbit and support defense, intelligence, and commercial missions such as technology demonstrations, hypersonic and materials testing, in-orbit servicing, and in-space manufacturing. The Delphi platform and its core components are engineered to withstand the thermal and structural demands of atmospheric re-entry, enabling routine return and recovery of both the satellite bus and payload to support expedited technology development.

…Under the partnership, Southern Launch will provide end‑to‑end services for each orbital re-entry, including regulatory approvals, range operations, air and maritime coordination, and recovery operations.

This is the second American orbital capsule company to sign with Southern Launch. Varda was the first, and it did so because red tape in the U.S. made use of an American drop zone impractical. It appears Lux Aeterna has come to the same conclusion, and thus went to Australia instead.

This is an issue that needs to be addressed by the Trump administration. It is absurd that red tape is forcing American capsules to land in another country on the other side of the globe.

Isar ready for second launch attempt

11:26 am

In a press release earlier this week, the German rocket startup Isar Aerospace announced that it has successfully completed static fire tests of both stages of its Spectrum rocket, and is now prepared for a second attempt to reach orbit, nine months after the first attempt failed seconds after liftoff.

Though its press release made no mention of a launch date, rocketlaunch.live is listing that attempt for January 13, 2026, taking place at Norway’s Andoya spaceport.

If successfully, the launch will achieve a number of milestones. First, Isar will be the first German rocket company ever to launch a rocket into orbit. Germany’s government has for decades been a partner in Arianespace, the commercial arm of the European Space Agency, but no private company has ever built and launched its own rocket.

Isar’s success will also beat out the German startup Rocket Factory Augsburg and Spanish startup PLD, both of which are getting close to a first launch as well.

Second, the launch from Andoya will make that spaceport the first in Europe to place a satellite into orbit, despite coming to this commercial spaceport competition years after two of Great Britain’s proposed spaceports in northern Scotland. While Norway’s government has greased the rails, removing red tape to allow Andoya to become operational quickly (and thus attracting rocket startups like Isar, Firefly, and Astrobotic), Great Britain’s red tape has delayed its spaceports for years, while putting one rocket company, Virgin Orbit, out of business.

Russia launches more than fifty satellites

11:03 am

Russia today successfully launched more than fifty satellites, its Soyuz-2 rocket lifting off from its Vostochny spaceport in far eastern Russia.

The main payloads were two Russian Earth imaging satellites, both dubbed Aist-2T

In addition to the launch of the Aist-2T pair, the same Soyuz-2-1b rocket was also booked to carry 50 dual-purpose secondary payloads, ranging from light-weight experimental satellites down to an assortment of educational cubesats and a small carrier platform, itself designed to release the tiniest satellites known as pikosats. A total of 33 payloads were to be deployed from 17 launch containers provided by Moscow-based Aerospeis Kapital.

The most notable secondary payloads on the mission were two Marafon-IoT experimental satellites, developed at ISS Reshetnev and intended for paving the way to the so-called Internet-of-Things satellite system, however, by the time they reached the launch pad, the main project was facing cancellation due shrinking Russian space budget.

The most significant foreign payload on the Aist-2T mission was a trio of Iranian dual-purpose satellites all intended for remote-sensing of the Earth’s surface. Other small foreign payloads were ordered by various institutions in Montenegro, Kuwait, Qatar, Ecuador and Belarus. [emphasis mine]

Russia continues to show an inability to get anything of substance into orbit due to a lack of capital, caused by Putin’s policies of squelching competition and invading other countries.

The leaders in the 2025 launch race:

168 SpaceX
88 China (a new record)
18 Rocket Lab
17 Russia

SpaceX still leads the rest of the world in successful launches, 168 to 148.

China launches nine more satellites in Guowang constellation

12:18 pm

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)
