Cool image time! Rather than posting another Mars orbital image, I decided today to delve into the archive of pictures taken by the Cassini orbiter during the thirteen years it circled Saturn, from 2004 until 2017. The picture to the right, cropped to post here, was released on December 14, 2015, and is just one example of the many breath-taking photographs that the Cassini science team took during that mission. From the caption:

Like a cosmic bull’s-eye, Enceladus and Tethys line up almost perfectly for Cassini’s cameras. Since the two moons are not only aligned, but also at relatively similar distances from Cassini, the apparent sizes in this image are a good approximation of the relative sizes of Enceladus (313 miles across) and Tethys (660 miles across).

This view looks toward the un-illuminated side of the rings from 0.34 degrees below the ring plane. The image was taken in red light with the Cassini spacecraft narrow-angle camera on Sept. 24, 2015.

The image was obtained at a distance of approximately 1.3 million miles from Enceladus. Image scale on Enceladus is 7 miles per pixel. Tethys was at a distance of 1.6 million miles with a pixel scale of 10 miles per pixel.

Enceladus is in the foreground, and is the planet that has what scientists have labeled tiger stripe fractures that vent water and other material, including carbon molecules.

Astronomers discover a “surprisingly mature” cluster of galaxies in early universe

11:18 am

Proto galaxy cluster
Click for original image.

The uncertainty of science strikes again! Astronomers using both the Webb Space Telescope and the Chandra X-ray Observatory now think they have discovered a just-forming protocluster of galaxies only one billion years after the Big Bang, when such galaxy clusters should not yet exist.

You can read their paper here [pdf]. The image to the right, cropped and reduced to post here, shows the Webb infrared data as the background of stars and galaxies, with the galaxies thought to be part of this protocluster circled. The blue cloud is Chandra’s infrared data. From the press release:

The Chandra and Webb data reveal that JADES-ID1 contains the two properties that confirm the presence of a protocluster: a large number of galaxies held together by gravity (Webb sees at least 66 potential members) that are also sitting in a huge cloud of hot gas (detected by Chandra). As a galaxy cluster forms, gas falls inward and is heated by shock waves, reaching temperatures of millions of degrees and glowing in X-rays.

What makes JADES-ID1 exceptional is the remarkably early time when it appears in cosmic history. Most models of the universe predict that there likely would not be enough time and a large enough density of galaxies for a protocluster of this size to form only a billion years after the big bang. The previous record holder for a protocluster with X-ray emission is seen much later, about three billion years after the big bang.

It increasingly appears that there are aspects of the universe we simply do not yet understand, which in turn make our theories of its birth and formation either incomplete or invalid. Those theories might be right in principle, but the data suggests they are wrong in detail.

New ground-based space antenna startup raises $100 million and wins $50 million Space Force contract

10:24 am

In a clear sign that the space industry in space now requires increased support on the ground, the ground-based space antenna startup, Northwood Space, this week announced it has raised $100 million in private investment capital even as it simultaneously won a $50 million Space Force contract.

The funding round, announced January 27, was led by Washington Harbour Partners and co-led by Andreessen Horowitz. The financing came on the heels of a $49.8 million contract that was signed with the United States Space Force to help improve the “satellite control network,” which “handles a huge variety of consequential space missions for our government,” said Bridgit Mendler, founder and CEO.

Northwood is an end-to-end ground infrastructure provider for space missions. In other words, it manufactures and deploys antennae systems, which are smaller than older models, that allow Earth to communicate with satellites in space.

Northwood was only formed three years ago, so its success is an clear indication that there is a real need for more and better ground-based facilities.

German government hires German startup Polaris Spaceplanes to build reusable two-stage hypersonic plane

The German government yesterday awarded a contract to the German startup Polaris Spaceplanes to build and fly a reusable two-stage hypersonic plane by 2027.

On 27 January, POLARIS Spaceplanes announced that it had been awarded a contract by the Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw) to build a fully reusable, horizontal take-off, two-stage hypersonic vehicle. The primary application of the Hypersonic Test and Experimentation Vehicle (HYTEV) will be as a hypersonic testbed for scientific and defence-related research. A variant of the vehicle with an expendable upper stage will also be capable of deploying small satellites into low Earth orbit.

According to the company, the HYTEV will be roughly the size and take-off mass of a fighter jet. The main stage will be powered by two turbofans and one of the company’s in-house developed aerospike rocket engines. The turbofans will be used for take-off and landing, and the rocket engine will accelerate the vehicle before upper-stage deployment. The upper stage will be entirely rocket-powered, with imagery accompanying the announcement appearing to show a more conventional rocket engine configuration compared with the aerospike engine equipped to the main stage. After completing its mission, it will likely be recovered under controlled glide conditions or potentially by a parachute or parafoil.

This deal appears to be an upgrade to a February 2025 German government deal with Polaris. It also follows Polaris’s successful use of an aerospike engine on a prototype test flight in 2024. While the company has shown some success, doing more than a dozen test flights with small scale prototypes (as shown in the image to the right), this program and schedule still seems quite ambitious.

Ariane-6 gets a new government launch contract

9:45 am

The European Space Agency, one agency among many
The European Space Agency, one European
agency among many

The government rocket of the European Space Agency (ESA), the Ariane-6, yesterday won a new launch contract to place a pair of Galileo GPS-type satellites into orbit for the European Union (EU).

Arianespace announced today at the European Space Conference in Brussels the signature of the launch contract with the European Union Agency for the Space Programme (EUSPA), under the delegation of the European Commission, to orbit the second pair of second-generation satellites of the Galileo constellation (Galileo L18) on board an Ariane 6 launcher. With this signature, the European Commission and the EUSPA are formalizing the launch contract of Galileo L18, following the initial mission allocation to Arianespace made in April 2024.

All told this will be Ariane-6’s fifth launch of GPS-type satellites for the EU, which appears committed to Ariane-6, even though this expendable rocket costs much more than SpaceX’s Falcon 9, in order to promote European sovereignty. Eventually Europe will develop more cost effective private rockets (in about a decade), but until then its access to space will be limited by cost.

And the extra cost is not simply the expendable nature of Ariane-6. Note also the many layers of bureaucracy listed in the quote above. For the European Union there the European Union Agency for Space Programme, working under the supervision of the EU’s European Commission. It signed a deal with Arianespace, which represents the European Space Agency as its commercial rocket division.

That’s four different bureaucracies, two within the European Union and two more related to Europe’s space effort. Each adds cost to the launch, as well as the need for complex negotiations that delay any deal.

SpaceX launches GPS satellite

9:06 am

SpaceX last night successfully launched a GPS satellite for the Space Force, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The Space Force had originally hired ULA to launch this satellite, but two weeks ago it switched launch provider to SpaceX. Apparently the military wanted this satellite launched now, and for some reason ULA could not do it, even though the Vulcan rocket was supposedly ready for launch.

The first stage completed its fifth flight, landing on a drone ship in the Atlantic. The two fairing halves each completed their second flight.

The 2026 launch race:

11 SpaceX
5 China

Scientists produce new estimate of the thickness of Europa’s icy crust

5:23 pm

Europa in true color

September 2022 fly-by. Click for full image.

Using data produced by Juno during a 2022 close-fly of Jupiter’s moon Europa, scientists have made a new estimate of the thickness of Europa’s icy crust, approximately 18 miles thick with a 6-mile margin of error.

In other words, their estimate could be as small as 12 miles thick, or as large as 24 miles thick.

You can read their paper here. From their abstract:

For the idealized case of pure water ice, the data are consistent with the existence of a thermally conductive ice shell with a thickness of 29 ± 10 km [18 ± 6 miles] and with the presence of cracks, pores or other scatterers extending to depths of hundreds of metres below the surface with a characteristic size smaller than a few centimetres in radius. An ice-shell salinity of 15 mg kg−1, as indicated by models based on terrestrial marine ice, would reduce our estimate of the thickness of the ice shell by about 5 km, substantially less than our 10 km uncertainty. The low volume fraction, small size and shallow depth of the scatterers indicate that the fracture interfaces observed at Europa’s surface are alone unlikely to be capable of carrying nutrients between the surface and the ocean. [emphasi mine]

The highlighted sentence is the important one. If this new estimate is right, than the unidentified reddish material that appears to leak out of the long ridgelike cracks on Europa’s surface, clearly visible in the picture to the right, are not coming from any underground ocean. The distances are too large.

Other estimates have suggested that ice crust could be as thin as 2 miles, but like this research the uncertainties are very large.

Meanwhile, the Juno mission is still alive, though essentially winding down operations. The mission was expected to officially end at the end of September 2025, when its budget ran out, but the just passed budget included enough money to keep it going, albeit at a relatively low level. According to the orbiter’s webpage, it will continue to orbit Jupiter, its orbit degrading naturally until it falls into Jupiter to burn up. As it does so data will continue to be collected, though at a much lower rate.

Windswept Martian volcanic ash?

2:35 pm

Volcanic ash on Mars?
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on November 30, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this simply as “Features,” the vagueness of which I can understand after digging in to get a better idea of the location and geography.

The location, as shown by the white dot on the overview map below, is inside the Medusa Fossae Formation, the largest volcanic ash field on Mars that is thought to be the source of much of the red planet’s dust. That ash field is large and very deep, and was put down more than a billion years ago when the giant volcanoes of Mars were active and erupting. Thus it is well layered, and many images of that ash field show that layering exposed by the eons of Martian wind scouring its surface.

In this case, that scouring appears to have produced this feathery surface, though the origin of those ridges might have instead come from volcanic flows that are now hardened. Or we could be looking at ancient channels produced by ice or water, though that would have to have been a very long time ago, as this image is located in the Martian dry tropics, where no near surface ice presently exists.

Astronomers use AI to discover hundreds of weird galaxies in Hubble archive

10:23 am

Weird galaxies in the Hubble archive, found with AI
Click for original image.

In what is a perfect example of the proper use of artificial computer intelligence (AI), astronomers have now used this programming to analyze almost 100 million images taken by the Hubble Space Telescope over the decades to find any galaxies hidden there that have “anomalies” or unusual shapes.

The team analyzed nearly 100 million image cutouts from the Hubble Legacy Archive, each measuring just a few dozen pixels (7 to 8 arcseconds) on a side. They identified more than 1,300 objects with an odd appearance in just two and a half days — more than 800 of which had never been documented in scientific literature.

The six galaxies to the right are just a small sample. All six were previously unidentified, and include “three lenses with arcs distorted by gravity, one galactic merger, one ring galaxy, and one galaxy that defied classification” (the galaxy at the top left). From the European Space Agency’s (ESA) press release:

The strange, bi-polar galaxy seen here is certainly anomalous, with its compact, swirling core and two open lobes at the sides. Exactly what kind of galaxy it is is unclear, and it was not previously known to astronomers.

As noted in the first link, the volume of data that astronomers are now collecting from ground-based and orbiting telescopes — many of which are survey telescopes that photograph the entire sky repeatedly — has actually become a problem. They have great data, but don’t have the time or human resources to study it sufficiently. Even employing large numbers of ordinary citizens, working at home with their own computers, can’t get the job done.

This is the kind of grunt work that AI is ideally made for. It can quickly review the data and identify objects that don’t fit normal expectations. Humans then can do the real work, finding the most interesting of these strange objects, such as the top left galaxy, and devote human creativity to studying it.

Musk: Next Starship/Superheavy test launch in mid-March

9:39 am

According to a recent tweet by Elon Musk , the next Starship/Superheavy test launch will occur “in 6 weeks,” placing that launch sometime in mid-March.

Musk provided no other information, but this announcement suggests the company’s engineers now understand and have corrected the issues that caused two Superheavy ruptures during two different tank tests in recent weeks. It also suggests that the launchpad repairs and upgrades will soon be completed, and that a new version 3 Superheavy prototype is ready to go, replacing one that was damaged during those tank tests.

The mission specifics however remain unclear. SpaceX could repeat the flight path of the last few tests, in an orbit low enough so that the atmosphere will bring Starship down over the Indian Ocean. In such a flight the company would test refueling within Starship, restarts of its Raptor engines, and deployment of dummy or even real Starlink satellites.

It is possible however that this next test flight will go into a full orbit, and circle the Earth once or several times. SpaceX has said that in 2026 it intends to do a Starship refueling test using two Starships, launched several weeks apart. To do this more ambitious mission however it first needs to do at least one full orbital flight of Starship. Since the company has already tested on previous orbital test flights the restart of Starship’s Raptor engines — proving its capability to do a controlled re-entry — there really is no reason it can’t go for a full orbit on the next flight. There is even the possibility that Starship will come back to Boca Chica and be caught the company’s tower chopsticks, though this remains unconfirmed.

Avio gets two new launch contracts for its Vega-C rocket

9:16 am

The Italian rocket company Avio has won two separate launch contracts for its Vega-C rocket, one from Airbus and a second from Brazil.

It also appears that these two contracts are the ones that Avio touted in late December for a total of $117 million, but did not reveal the customers at the time.

First, Brazil’s government will pay Avio $35.6 million to use the Vega-C rocket to launch its Amazonia-1B Earth observation satellite in 2027. This contract was obtained though the launch services company SpaceLaunch and is likely the deal first announced in September without mention of the customer.

Next, Airbus will use the Vega-C in 2028 to launch the first satellite in its Pléiades Neo Next Earth observation satellite constellation. Though the contract price was not announced, it is likely $84.4 million, the difference between the $117 million total for the two contracts and the $35.6 million Brazil is paying.

The price on both launch contracts illustrates how the competition from SpaceX and Rocket Lab is forcing launch costs down. A decade ago launches never cost less than $100 million. Now they always do, and the Brazil price of $35.6 million indicates even lower prices in the future.

NASA targeting January 31, 2026 for Artemis-2 dress rehearsal countdown

NASA engineers are now targeting January 31, 2026 for the manned dress rehearsal countdown of the Artemis-2 SLS rocket and Orion capsule.

The upcoming wet dress rehearsal is a prelaunch test to fuel the rocket. During the rehearsal, teams demonstrate the ability to load more than 700,000 gallons of cryogenic propellants into the rocket, conduct a launch countdown, and practice safely removing propellant from the rocket without astronauts inside the spacecraft.

During several “runs,” the wet dress rehearsal will test the launch team’s ability to hold, resume, and recycle to several different times in the final 10 minutes of the countdown, known as terminal count. The rehearsal will count down to a simulated launch at 9 p.m. EST, but could run to approximately 1 a.m. if needed.

This rehearsal will include the four-person crew inside the Orion capsule, which will once launched take them in a wide ten-day Earth orbit that will swing them past the Moon and then back to Earth. The crew entered quarantine at the end of last week to reduce the chance they will catch any illnesses prior to launch.

This mission carries great risk, as the capsule’s life support system has never been used in space before, while the viability of its heat shield remains questionable.

“AI isn’t getting smarter. We are getting dumber.”

2:20 pm

Link here. The point the op-ed makes is fundamental: AI cannot add anything to the information it has. It might be able to compile that information well, but its analysis is always going to be limited because it has no true creative spirit. It is merely a software program, albeit a very sophisticated one.

This quote from the essay will give you the sense:

Maybe you just use AI to clarify your thoughts. Turn the mottle of ideas in your head into coherent communicable paragraphs. It’s OK, you say, because you’re reviewing the results, and often editing the output. You’re ending up with exactly what you want to say, just in a form and style that’s better than any way you could have put it yourself.

But is what you end up with really your thoughts? And what if everyone started doing that?

Stripping the novelty and personality out of all communication; turning every one of our interactions into homogeneous robotic engagements? Every birthday greeting becomes akin to a printed hallmark card. Every eulogy turns into a stamp-card sentiment. Every email follows the auto-response template suggested by the browser.

We do this long enough and eventually we begin to lose the ability to communicate our inner thoughts to others. Our minds start to think in terms of LLM prompts. All I need is the gist of what I want to say, and the system fills in the blanks. [emphasis in original]

Comments are of course welcome. But please read the full essay before doing so.

Dragonfly’s rotors complete testing

12:07 pm

According to a press release yesterday from the Applied Physics Lab (APL) in Maryland that is building the Dragonfly helicopter that is going to Saturn’s moon Titan, the rotors have completed the first round of testing, and are now about to undergo “fatigue and cryogenic trials under simulated Titan conditions.”

Over five weeks, from August into September, the team evaluated the performance of Dragonfly’s rotor system — which provides the lift for the lander to fly and enables it to maneuver — in Titan-like conditions, looking at aeromechanical performance factors such as stress on the rotor arms, and effects of vibration on the rotor blades and lander body. In late December, the team also wrapped up a set of aerodynamics tests on smaller-scale Dragonfly rotor models in the TDT [Transonic Dynamics Tunnel].

This quote about the manufacture of the rotors however stood out the most:

Pennington and team cut Dragonfly’s first rotors on Nov. 1, 2024. They refined the process as they went: starting with waterjet paring of 1,000-pound aluminum blocks, followed by rough machining, cover fitting, vent-hole drilling, and hole-threading. After an inspection, the parts were cleaned, sent out for welding, and returned for final finishing.

“We didn’t have time or materials to make test parts or extras, so every cut had to be right the first time,” Pennington said, adding that the team also had to find special tools and equipment to accommodate some material changes and design tweaks. [emphasis mine]

In other words, this is another hardware-poor NASA project. What they build is what they have. No time or money for testing of prototypes.

This mission is really pushing the envelope, possibly more than any NASA planetary probe in a half century. I just hope they get it right.

Russia delays launch of its own “Starlink” constellation

9:33 am

I’m shocked, shocked! According to news reports in Russia yesterday, Roscosmos has now delayed the initial launches for its own copycat “Starlink” constellation because the production of the satellites has fallen behind schedule.

In September 2025, Roscosmos head Dmitry Bakanov promised that by the end of 2025, the first 300 satellites would begin to be deployed in orbit as part of the Rassvet project. They are supposed to become “an analogue of the Starlink system” and provide “access to the internet at any geographical point.”

According to the publication, the postponement of the launch of the first 16 devices until 2026 may be due to the fact that the required number of satellites has not yet been assembled.

The project is being run by a Bureau 1440, supposedly a private Russian commercial company that is providing two thirds of the $5.7 billion budget, with the Russian government picking up the difference. It claims it will begin launching this year and have 318 satellites in orbit by 2028.

Wanna bet? Russia has not been able to complete any space project on time in decades, and even when its projects do finally launch, each routinely has had serious technical and quality control issues.

ESA awards startup Rocket Factory Augsburg a two-launch contract

9:23 am

Screen capture of test failure
Screen capture from video of the RFA-1
test failure in August 2024. Note the flame
shooting out sideways.

The European Space Agency (ESA) yesterday awarded the German rocket startup Rocket Factory Augsburg a two-launch contract under its “Flight Ticket Initiative”, designed to encourage the development of a commercial independent European launch market.

With these signatures between ESA and Rocket Factory Augsburg (RFA), two more missions will be launched with the RFA One rocket from Saxavord Spaceport in the UK as part of the Flight Ticket Initiative. ESA and the European Commission have thus once again placed their trust in RFA as a future launch service provider.

…The Lurbat mission will fly a collection of demonstrator technologies and is developed by Added Value Solutions based in Spain. … A second mission will see the launch of two CubeSats developed under ESA contract by the Spanish company Indra Space. The CubeSats will hold five experiments selected by the European Commission through the Horizon Europe IOD/IOV call for Expression of Interest

Rocket Factory also has a launch contract with the German government. However it needs to first complete the first launch of its RFA-1 rocket. That launch was originally supposed to occur in 2024 but was canceled when the rocket’s first stage was destroyed during a static fire test on its Saxavord launchpad that year.

Since then the company has released little information about the rocket’s status. According to this news report today, it hopes to finally do that test launch this year. It better do it soon, as there is a slew of other European rocket companies that intend to do the same.

And then of course there is the question of the Saxavord spaceport and the red tape that has crippled all the spaceports in Great Britain. Both Saxavord and Rocket Factory have previously gotten their launch licenses from the UK’s Civil Aviation Authority (CAA), but it is unclear if those licenses remain valid, especially after the static fire explosion. Based on its past behavior, the CAA could have pulled the licenses, and is now reviewing the whole thing.

If so, it might take years for both to get an approval again. In fact, this might very well be the reason Rocket Factory didn’t launch in 2025.

Blue Origin to reuse first stage on next New Glenn flight

9:48 am

New Glenn first stage after landing
The New Glenn first stage after landing
in November.

In a sign that Blue Origin’s CEO David Limp is beginning to reshape the previously slow culture of the company, it announced yesterday that its next New Glenn launch, set for no earlier than late Feburary, will reuse the first stage that the company successfully landed on the last New Glenn flight in November 2025.

If this launch takes place as scheduled, it will mean Blue Origin was also able to inspect, refurbish as necessary, and prepare that used first stage in a little over three months. While not as fast as SpaceX is now doing with its Falcon 9 first stages, it is still remarkably fast, considering it is the first booster Blue Origin has recovered. SpaceX didn’t attempt its first reuse of a recovered first stage for a little more than a year after its first successful landing.

Of course, SpaceX was breaking new ground, so more caution and engineering work was needed. Blue Origin has the advantage of almost a decade of experience to draw upon. Nonetheless, Blue Origin’s decision to reuse so quickly is still impressive. It suggests its engineering behind New Glenn is very robust.

Limp still has work to do, however, to get Blue Origin operating with the speed matching SpaceX. This third launch of New Glenn will place an AST SpaceMobile Bluebird satellite into orbit, because the original payload, Blue Origin’s unmanned Blue Moon MK1 lunar lander, wasn’t ready as planned, and is still undergoing final ground check-ups.

Blue Origin’s proposed TeraWave constellation: Is it really competition with SpaceX?

1:36 pm

TeraWave logo

Blue Origin announced yesterday that it going to build a major satellite constellation — dubbed TeraWave and comprising more than 5,000 satellites — to provide internet service to the globe while also providing data center capability for those companies that wish to establish space-based cloud computing facilities.

It plans to begin launching satellites in 2027.

As I noted in today’s quick links below, such a story would normally merit a full post, “but considering Blue Origin’s inability to get almost anything off the ground, this proposal doesn’t deserve that much coverage at this point.” I just can’t get excited about any Blue Origin proposal, until they actually start launching it. For almost a decade this company has been making these kind of grand announcements, and has only so far managed to achieve one, its New Glenn rocket. And that has come years late and at a pace that is glacial.

Not surprisingly, the mainstream propaganda press immediately went bonkers over this proposal, immediately declaring most absurdly that TeraWave is already a major challenger to SpaceX’s Starlink constellation. Here are just a few very typical examples:

This adulation by the mainstream press of Bezos is far from unusual. For reasons that baffle me, the propaganda press has consistently considered any project proposal coming from a Jeff Bezos’ company to instantly be God’s gift to humanity. For more than a decade now it has been touting Blue Origin as the company that SpaceX needs to beat, flipping reality on its head. Now it ranks Blue Origin’s TeraWave constellation a major Starlink rival, when it is at least two years from even launching its first satellite.

There is one aspect of this story however that does deserve to be highlighted because it appears no one else is noticing it, which is why I after some thought I decided to write this full post. » Read more

Isar postpones 2nd Spectrum rocket launch attempt, no new date set

10:24 am

Proposed or active spaceports in North Europe
Proposed or active spaceports in North Europe

The German rocket startup Isar Aerospace yesterday canceled its second attempt to launch its Spectrum rocket from Norway’s Andoya spaceport, citing an issue with a “pressurization valve”.

We are standing down from today’s launch attempt to address an issue with a pressurization valve. The teams are currently assessing the next possible launch opportunities and a new target date will be announced shortly.

The update also stated the company is moving to a “new launch window” without noting the dates of that window. This statement however suggests that no new launch attempt will occur for at least a month. And considering it is winter at Andoya in the high north, it is quite possible the launch will be delayed until March.

Meanwhile, Andoya continues to lead the race to become the first spaceport in Europe to achieve an orbital launch. Sweden’s Estrange spaceport is limited because of its interior location. The two sea platforms proposed for the North Sea are not yet ready.

And the United Kingdom has effectively eliminated itself from the competition. Its bureaucracy and Byzantine regulations have now put two rocket companies out of business, and that same red tape (combined with location opposition) has essentially shut down the Sutherland spaceport. I doubt there are any rocket companies willing to deal with the UK at this point.

French smallsat rocket startup Latitude targeting a first launch in early ’27

9:16 am

In a long interview released yesterday, the CEO of the French smallsat rocket startup Latitude revealed that they expect to do the first launch its Zephyr rocket no later than early ’27, and that launch will not take place in French Guiana, where it is presently developing facilities for launches.

The spaceport at French Guiana is developing a single launchpad designed to serve multiple rocket companies, and so it can’t handle Latitude’s planned launch rate. Thus the company is presently negotiating with other spaceports for its first launch, to give it more flexibility.

Zephyr will also not be reusable, as the company has determined that it isn’t profitable for small rockets.

Latitude has deliberately chosen not to pursue first-stage reusability for Zephyr, a decision Maximin defended with detailed economic analysis. “Our calculations show that with that size, it is not economically viable,” he stated, noting that even with parachute recovery, the maintenance costs and performance penalties outweigh manufacturing savings for a rocket of Zephyr’s class. He pointed to Rocket Lab’s paused reusability efforts as validation: “They have stopped it, despite having done everything. I think it’s not that profitable, if not at all.”

If the company upgrades to a larger rocket in the future it plans to revisit this issue.

Video of the interview is available here.

Rocket Lab experiences a tank failure during Neutron pressure test

8:40 am

According to an update posted yesterday, during a pressure test of a first stage tank for Rocket Lab’s new Neutron rocket, the tank ruptured.

As the company pushes Neutron to the limits and beyond to qualify its systems and structures for launch, qualification testing of the Stage 1 tank overnight resulted in a rupture during a hydrostatic pressure trial. Testing failures are not uncommon during qualification testing. We intentionally test structures to their limits to validate structural integrity and safety margins to ensure the robust requirements for a successful launch can be comfortably met.

There was no significant damage to the test structure or facilities, the next Stage 1 tank is already in production, and Neutron’s development campaign continues while the team assesses today’s test outcome.

The team is reviewing the Stage 1 test data, which will determine the extent of the impact to Neutron’s launch schedule.

The company was aiming to do Neutron’s first launch in the first quarter of this year. Though the press release is vague on this point, its language suggests the rupture did not occur at the expected maximum pressure, but took place sooner, at a lower pressure level. If the tank failed at maximum pressure, then there would be no need to reconsider the launch schedule. A failure at lower pressures would require changes in tank design, and thus a launch delay.

The company says it will provide an update in February, which further suggests a launch in the first quarter is now unlikely.

Orbital tug startup Starfish Space wins $52.5 million Space Force contract to de-orbit its defunct satellites

8:01 am

Remora rendezvous
Images taken by Starfish’s camera during rendezvous
maneuvers.

The orbital tug startup Starfish Space yesterday announced it has been awarded a $52.5 million contract from the Space Force’s Space Development Agency (SDA) to use its Otter tug to de-orbit satellites when they have reached their end-of-life.

Under the contract, Starfish Space will build, launch, and operate an Otter spacecraft in low Earth orbit (LEO) to safely and efficiently dispose of SDA satellites at the end of their operational lives. The mission begins with an initial deorbit, with options for multiple additional deorbits, enabled by Otter’s significant capacity and ability to service several satellites in a single mission. The mission is targeting launch in 2027.

While a number of contracts have been issued in the U.S., Europe, and Japan to demonstrate de-orbit technology, this is the first operational contract ever issued. Moreover, I don’t think any of those other demo missions have actually achieved a de-orbit as of yet. Starfish itself has only successfully demonstrated rendezvous and proximity capabilities on two missions, with a third a failure. In the most recent late last year (as shown by the image on the right), Impulse’s Mira tug used Starfish software and camera to move within 1.2 kilometers of another Mira tug.

As for docking, its Otter Pup tug has flown two missions. The first failed in 2023 when both spacecraft began spinning unexpected. The second was supposed to achieve a docking, but after completing rendezvous maneuvers the company has provided no new updates. As far as we know, the docking never occurred or was a failure.

Nonetheless, it appears Starfish’s overall recent performance convinced the Space Force it could handle this new de-orbit contract.

Communications resume with Mars

1:02 pm

First images back from Curiosity and Perseverance
Go here and here for the original images.

It appears the solar conjunction that has blocked all communications with the rovers and orbiters for the past three weeks around Mars has now fully ended, with the first new images appearing today from both Curiosity and Perseverance.

The two images to the right were downloaded today. The top image was taken on January 20, 2026 by Curiosity’s front hazard avoidance camera. It appears to be looking uphill in the direction the rover is soon to travel, climbing Mount Sharp. If you look closely you can see the mountain’s higher ranges on the horizon, just to the right of the rover itself.

The bottom picture was actually taken on January 15, 2026 by Perseverance, but was only downloaded today. Both science teams had programmed their rovers to take images throughout the conjunction, scheduled for download when communications resumed.

The picture was taken by Perseverance’s left high resolution camera located on top of the rover’s mast. It looks down at the ground near the rover at the pebbles and rocks that strewn the relatively smooth surface of the terrain west of Jezero crater.

Neither image is particularly ground-breaking. What is important however is that both images prove the rovers are functioning as expected. Expect a lot more data to arrive in the next few days, all gathered during three weeks of blackout.

Haven-1 launch delayed until 2027

According to Vast’s CEO, Max Haot, the launch of its single module Haven-1 space station has now been pushed back to the first quarter of ’27.

Last Saturday (January 10) we reached the key milestone of fully completing the primary structure, and some of the secondary structure; all of the acceptance testing occurred in November as well. Now we are starting clean room integration, which starts with TCS (thermal control system), propulsion, interior shells, and then moving on to avionics. And then final close out, which we expect will be done by the fall, and then we have on the books with NASA a full test campaign at the end of the year at Plum Brook. Then the launch in Q1 next year.

Until recently the company had been targeting a launch in the first half of 2026. This is a delay of almost a full year, and suggests the previous launch date has not been a serious target for quite some time.

Haot at the article at the link provides some new details about the manned missions to the station. It will launch unmanned, and after check-out in orbit that could last two weeks or longer, a professional SpaceX Dragon crew will fly a two-week mission there to do further check-outs.

After this up to three more two-week missions are planned, with Vast already having a deposit for the first. It also is willing to do more during Haven-1’s three year lifespan.

More and more it appears to me that in my rankings below of the five commercial space stations presently under development, the top three space stations are practically tied. And of the five stations, three are hoping to begin launching modules in the ’27-’28 time frame.

French startup The Exploration Company negotiating purchase of UK rocket startup Orbex

In what appears to be a direct consequence of British red tape blocking Orbex from launching in the past four years, it is now in negotiations to sell its assets to the French startup The Exploration Company.

On 21 January, Orbex published a brief press release stating that a letter of intent had been signed and that negotiations had begun. The company added that all details about the transaction remain confidential at this stage. A statement from Orbex CEO Phil Chambers suggests that the company’s financial position factored into its decision to pursue a buyer. “Our Series D fundraising could have led us in many directions,” said Chambers. “We believe this opportunity plays to the strengths of both businesses, and we look forward to sharing more when the time is right.”

Let me translate: In 2022 Orbex had set up a factory close to the proposed Sutherland spaceport on the north coast of Scotland, had signed a 50 year lease with that facility to launch its Prime rocket there, had built a launch platform and tested a prototype of the rocket, and was poised to do its first launch. All it needed was license approvals from the United Kingdom’s Civil Aviation Authority (CAA).

And then it waited, and waited, and waited, and waited. By 2024 it gave up on Sutherland, because the authorities (local and national) kept rejecting its spaceport license for environmental and political reasons. It switched its launch site to the SaxaVord spaceport on the Shetland Islands, pushing back that first launch to 2026. Along the way the UK gave it a $25 million grant, likely to keep the company above water because the UK was blocking its ability to launch.

All for naught. It is very clear Orbex has run out of cash waiting, and is now looking to salvage its work by selling everything to the French company, which so far has focused on building a cargo capsule to supply the upcoming commercial space stations.

If the sale goes through, do not be surprised if Orbex’s assets exit the UK entirely. And at that point, the CAA’s red tape can be given credit for destroying a second rocket company, following Virgin Orbit.

JAXA releases preliminary results of investigation into December 2025 H3 rocket launch failure

8:01 am

Japan's space agency JAXA

JAXA yesterday released the preliminary results of its investigation into upper stage failure during the December 2025 launch of its H3 rocket.

Previously the agency had indicated it believed the cause was linked to the separation of the rocket’s payload fairings. This new report changes that conclusion:

After liftoff, the No. 8 H3 rocket sustained damage to the section where the Michibiki No. 5 positioning satellite was mounted, when the satellite cover, called fairing, was separated.

In addition, the fuel tubing of the rocket’s second-stage engine was damaged, presumably causing combustion to stop earlier than planned, JAXA said in a progress report on its investigation into the failure at a meeting of a subgroup of a science ministry panel.

As the section was damaged, the satellite was no longer attached to the second stage of the rocket. The satellite fell off when the first stage separated.

In other words, as the fairings released, the satellite apparently deployed, damaging the fuel feed to the upper stage engine. It is as yet unclear whether the deployment system worked as intended, but did so prematurely, or if it failed entirely, allowing the satellite to fall away once the fairings separated.

At the moment Japan has no launch capability. Both of JAXA’s rockets, the H3 and the Epsilon-S are grounded due to launch failures. Meanwhile, the country has only recently begun to develop private launch companies, none of which are ready to launch.
