Another ESA rendezvous demo mission proposed

10:52 am

The European Space Agency (ESA) and the Luxembourg startup ClearSpace yesterday announced a new demo mission to test autonomous rendezvous and proximity maneuvers, scheduled to launch in 2027.

PRELUDE aims to validate autonomous rendezvous and proximity operations in real flight conditions. The mission will test high-accuracy tracking, navigation and maneuvering using a combination of vision-based and complementary sensors feeding onboard algorithms and autonomous, fault-tolerant guidance, navigation and control (GNC) software. The goal is to demonstrate full freedom of movement and safe, repeatable maneuvers around another spacecraft.

Sounds good, eh? Not so fast. ClearSpace has had a bunch of these missions proposed, and none has yet flown. In 2019 ClearSpace won an ESA contract to de-orbit an old piece of space junk by 2025. In 2023 however that mission was stymied when that space junk, a payload adapter from a 2013 launch of Vega rocket launch, was hit by another piece of space junk.

Both ESA and ClearSpace apparently had difficulties re-designing the mission. In 2024, the ESA forced a major shake-up in ClearSpace’s management and missions, with the established company OHB taking over the startup. Subsequently the mission was redesigned to de-orbit a different defunct satellite, but delayed until 2029.

In 2024 the United Kingdom gave ClearSpace and Japan’s Astroscale a contract to de-orbit two satellites in ’26. It is however not clear at this time whether that mission will launch as planned.

This new PRECLUDE mission is interesting in that it will test the rendezvous and proximity technology that ClearSpace must have for all the other de-orbit missions. In other words, those other missions were never possible, because ClearSpace didn’t have the capability to do them. This new mission appears designed to develop that capability.

I ask: Why wasn’t PRECLUDE scheduled first, in the first place? That it wasn’t reflects very badly on both ClearSpace and the ESA.

ESA funds Danish lunar orbiter

9:16 am

The European Space Agency (ESA) has agreed to fund the first Danish-built interplanetary probe, a smallsat lunar orbiter dubbed Mani that will launch in ’29 and map the Moon’s surface.

The Máni mission is a lunar mission that will use a satellite to map the Moon’s surface with high-resolution images and create detailed 3D maps. The goal is to make it safer for astronauts and lunar rovers to land and move around on the Moon. The satellite will orbit the Moon’s north and south poles, which are key areas for future human missions.

The mission will also map how light reflects from areas on the Moon that are used to study Earth’s ability to reflect sunlight onto the lunar surface – the so-called earthshine. This knowledge could improve our understanding of how Earth’s climate will evolve.

The University of Copenhagen leads the mission and is responsible for the mission’s Science Operations Center, which will plan which areas to map and analyze the vast number of images generated.[emphasis mine]

I love how this European press release about a lunar orbiter somehow makes its most important mission studying climate change on Earth. Utterly idiotic.

Mani will use the changing shadows to create detailed topographic maps. As it is unlikely it will be capable of providing better data than produced over the past sixteen years by Lunar Reconnaissance Orbiter (LRO), this mission is mostly an engineering demo by Denmark and the Danish startup, Space Inventor, that is building the satellite for a consortium of universities. If successful the satellite will possibly be able to replace LRO (which is going to fail sooner or later), and provide data on any lunar surface changes that occur in the future.

European Space Agency hacked

8:43 am

It appears some of the European Space Agency’s (ESA) servers have been hacked, with some of its internal data placed for sale on the web.

On 26 December, reports began to emerge on X claiming that ESA had suffered a significant data breach, with a hacker using the alias “888” offering more than 200 gigabytes of data for sale. According to the hacker’s listing, the allegedly compromised data included source code for proprietary software, sensitive project documentation, API tokens, and hardcoded credentials.

ESA has since issued a statement claiming the data breach was limited, but according to information posted on X, the breach included “Confidential internal documents (Airbus Defence & Space, Thales Alenia Space)” and “sensitive technical information related to space programs.”

I wouldn’t be surprised if China is bidding for this information right now. Then again, Europe’s space effort is so unimpressive compared to China that China might not see the information worth much.

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.

European sea-level satellite releases first data

10:39 am

First data from Sentinel-6B
Click for original.

The European Space Agency’s (ESA) Sentinel 6B satellite, launched a month ago, has now released its first sea-level data.

Following its launch on 17 November 2025, the first data from Sentinel-6B was captured on 26 November by the satellite’s Poseidon-4 altimeter. The image [to the right] is a combination of altimeter data from both the Sentinel-6 sea-level tracking satellites: Sentinel-6B and its twin, Sentinel-6 Michael Freilich, which was launched in 2020. The image shows the Gulf Stream current in the North Atlantic Ocean, off the eastern coasts of the US and Canada.

The Gulf Stream is a hugely important area of the North Atlantic Ocean, not only for the role it plays in global weather patterns and climate, but also because it’s a busy shipping route as well as a key ecosystem for marine species and therefore an important fishing zone.

What makes this particular government press release unusual is that though it is about a climate-related satellite, it makes no mention of global warming and how the sea level rise that has been recorded by the string of similar orbital satellites going back to 1993 is going to eventually drown us all. Maybe that’s because that total rise measured since 1993 equals only about 4 inches. That’s 4 inches of rise detected in more than three decades. At that rate, a little over an inch per decade, it will take centuries to drown anyone, but only those who refuse to walk a few feet to higher ground.

It could be the scientists and government PR hacks that are involved in writing this release also realized that the gig is up, and everyone now knows it, and it would only embarrass them further to push the global-warming hoax again.

Three launches and one scrub overnight

8:38 am

Falcon 9 1st stage after landing for 30th time
Falcon 9 1st stage after landing for 30th time

In the past twelve hours there was one launch abort at T-0 and three successful launches.

First, Japan’s space agency JAXA attempted to launch a GPS-type satellite using its H3 rocket, built by Mitsubishi. The countdown reached T-0 but then nothing happened. The launch was then scrubbed because of an issue in the ground systems. No new date was announced.

Next, Arianespace, the commercial division of the European Space Agency (ESA), launched two European Union GPS-type satellites, Galileos 33 and 34, its Ariane-6 rocket lifting off from French Guiana.

This was Arianespace’s seventh launch in 2025, the most it has achieved since 2021, though still about 20-30% lower than the numbers it generally managed in the 2010s.

Finally, SpaceX followed with two launches on opposite coasts. First, its Falcon 9 rocket launched 29 Starlink satellites from the Kennedy Space Center in Florida, the first stage completing its sixth flight by landing on a drone ship in the Atlantic.

Shortly thereafter the company launched another 27 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California. The first stage (B1063) completed its 30th flight, landing on a drone ship in the Pacific. This stage is now the third Falcon 9 booster to reach 30 reuses:

French startup The Exploration Company now building an in-orbit servicing spacecraft

12:28 pm

The French startup The Exploration Company, which has been developing an unmanned cargo spacecraft called Nyx to supply the commercial space stations under development, has now also gotten funds from the European Space Agency (ESA) to build an in-orbit spacecraft designed to provide refueling and servicing capabilities as well.

More information here.

In a 25 November update on its progress with an ESA-funded project, the company revealed that it is also working on a spacecraft called Oura, designed to refuel satellites in orbit, thereby extending their operational lifespan.

…As part of the 25 November update, the company announced that it had been awarded a Phase B2 contract for the InSPoC-1 programme. The Phase B2 development of the project will include activities up to Technology Readiness Level 6, which represents the development of a prototype and its demonstration in a relevant environment.

Once again, this contract from ESA is radically different than its past policy of building and owning everything itself. Instead, it is hiring this French company to develop this capability, which this French company will then own and be able to sell for profits to others.

A new study blasts the European Union’s proposed space act

9:28 am

The European Union
This label would be more accurate if it read
“NOT made in the European Union”

A new study [pdf] just published by the generally leftist Progressive Policy Institute (PPI) has concluded that the proposed European Union’s space act would do great harm to both the European and American space industries if passed and should be reconsidered.

The economic analysis relied on the European Commission’s own estimates of increased compliance costs. The commission projected that the act would increase the cost of manufacturing a satellite in Europe by 2% and a launch vehicle by 1%. The study assumed companies would pass those costs on to customers through average price increases of 2.7%. Depending on price elasticity in each market segment, that could reduce demand by 1% to 13.6%. The resulting loss to European companies would be 245 million euros ($285 million) in annual revenue and 100 million euros in profits, the study concluded.

U.S. companies exporting to the EU would also be affected. The study estimates that American firms would lose 85 million euros in annual revenue and 7 million euros in profits from reduced European sales.

Officials from PPI are further quoted as opposed to the act as presently written, calling for a complete rewrite before passage. As PPI is a decidedly partisan leftwing think tank, formed initially by the Democratic Party in 1989, this clear public opposition to this decidedly leftwing top-down law suggests support for the bill is truly waning.

The bill itself won’t be voted on until the summer of 2026, and even if approved would not begin going into effect until 2027. Considering the opposition from the U.S. and other member nations of the European Union and the European Space Agency, it would demonstrate the EU’s utter disregard for its claimed democratic principles if it were to go ahead and ratify it as presently written. And that remains a possibility.

German rocket startup Isar gets launch contract from ESA

8:25 am

The German rocket startup Isar Aerospace yesterday announced it has won a launch contract from the European Space Agency (ESA) to place a satellite carrying a number of experimental payloads into orbit before the end of 2026.

Satellite launch service company Isar Aerospace has signed a contract with the European Space Agency (ESA) to launch the ΣYNDEO-3 mission under the European Union’s In-Orbit Demonstration and In-Orbit Validation Programme (IOD/IOV). The launch will be carried out from Isar Aerospace’s dedicated launch complex at Andøya Space in Norway from Q4 2026.

…Redwire is the prime contractor for the ΣYNDEO-3 mission and will be delivering its Hammerhead spacecraft for a launch onboard Isar Aerospace’s launch vehicle Spectrum to a low Earth orbit (LEO). The spacecraft was built and integrated at Redwire’s state-of-the-art satellite processing facility in Belgium. The spacecraft aggregates 10 innovative payloads from six countries and institutions: Spain, France, Germany, Italy, Luxembourg and the EC.

Isar has yet to reach orbit with its Spectrum rocket. The first launch failed in March only seconds after launch. A second attempt is presently scheduled for sometime prior to December 21, 2025, lifting off from Andoya.

This is the second new launch contract Isar has announced in the past two weeks, and the third since September. At the moment it appears it is gaining momentum pending that first launch later this month, especially because a successful December launch would make it the first European rocket startup to successfully reach orbit.

Two launches today, by Arianespace and SpaceX

10:36 pm

Today there were two launches worldwide, one from South America and the second from the U.S.

First, Arianespace launched a South Korea imaging satellite from French Guiana, using the Vega-C rocket built and owned by the Italian rocket company Avio. Based on the July 2024 agreement, this is the next-to-last Vega-C flight that Arianespace will manage. After the next flight, Avio will take over management of its own rocket, cutting out this government middle man, though that agreement also allowed customers who had previously signed with Arianespace for later flights to stay with it as the managing organization.

Either way, Arianespace’s responsibilities will soon be limited solely to the Ariane-6 rocket, which itself has a limited future, being expendable and too expensive to compete in the present launch market.

Next SpaceX launched another 27 Starlink satellites into orbit, its Falcon 9 lifting off from Vandenberg Space Force Base in California. The first stage completed its 20th flight, landing on a drone ship in the Pacific.

As the Vega-C launch was only the sixth for Europe in 2025, it remains off the leader board for the 2025 launch race:

157 SpaceX (a new record)
74 China
15 Rocket Lab
15 Russia

SpaceX now leads the rest of the world in successful launches, 157 to 126.

A detailed look at Europe’s $1 billion commitment to its nascent commercial rocket industry

11:12 am

The European Space Agency

Link here. In announcing last week the European Space Agency’s (ESA) budget for the next three years, along with its general overall goals, the European council (dubbed CM-25) also apparently committed about $1.45 billion to its “European Launcher Challenge”, a program created in 2023 and designed to encourage the development of new European rockets, owned and operated by independent competing startups.

The article at the link provides a good overall summary of major increase in funding for this program, including which ESA countries are contributing the most and why. The key quote however is this:

In July 2025, ESA shortlisted Isar Aerospace, Rocket Factory Augsburg, PLD Space, MaiaSpace, and Orbex to proceed to the initiative’s next phase. It then began discussions with the host country of each company to assess its willingness to contribute to that company’s participation in the European Launcher Challenge.

During his post-CM25 address, ESA Director General Josef Aschbacher revealed that Member States had committed double the anticipated amount for the European Launcher Challenge, with the final figure exceeding €900 million. While the funding model’s structure suggests that only the UK, Spain, France, and Germany contributed, post-CM25 disclosures have indicated that a few additional countries also committed funds to the programme.

Germany appears to be the biggest contributor, supplying more than a third of the total fund ($422 million). This isn’t surprising, since Germany also has the most rocket startups, three, two of which are on that shortlist (Rocket Factory and Isar). Spain is next with a contribution of $196 million, aimed helping the rocket startup PLD. The UK is next, also contributing $196 million, likely to be used to support its Orbex startup that wants to launch from its Saxavord spaceport in the Shetland Islands.

A variety of other ESA nations, the Czech Republic, the Netherlands, and Norway, have also outlined their contributions, for a variety of space-related startups unrelated to rockets.

France also appears to have donated a significant amount, but has not made that number public. Its MaiaSpace startup is one on that shortlist above, but France also has one or two other rocket startups that might eventually qualify for aid.

The bottom line is that ESA here is committing funding to aid the development of rockets and space infrastructure that it won’t own or control, a major shift from its past policy of owning and controlling everything through its Arianespace pseudo-commercial company, what I call the Soviet- or government-run model. Instead, these ESA nations are going to help fund a range of competing private rockets, which will own the rockets and operate them for profit. ESA will simply become one of their customers, following the capitalism model that the U.S. switched to in the previous decade.

This increased commitment to capitalism in the ESA suggests that we should see some real progress by these startups in the next three years.

If you think the launch records being set this year are breath-taking, you ain’t seen nothin’ yet.

ESA’s member nations approve a major budget increase

9:28 am

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.
