Midnight repost: Genocide is coming to America

11:58 pm

Today I came across this tweet:

“At the time this aired this behavior was shocking to see. It literally looks exactly like how the left behaves on a regular basis now.”

The comparison between the tactics of the Nazi storm troopers and our modern Antifa thugs is apt. It illustrates the time we now live in. It also immediately made me want to repost my 2020 essay, Genocide is coming to America. That essay sadly remains pertinent, because the same unwillingness of decent Germans to believe the Nazis were a threat is the same unwillingness of too many modern Americans to believe the same thing about Antifa and the Democratic Party (which now enthusiastically uses Antifa as its storm troopers).

Worse, we now have a large minority of Americans who support this violent behavior. To them, violence is wholly justified against those who disagree with them. The proof of this horrible fact was demonstrated in the 2025 elections, where in New Jersey a Democrat won his election despite openly wishing death not only on a Republican but on that Republican’s children, while in New York an anti-Semitic communist won election as mayor.

Genocide is coming to America

In my last visit to Israel in 2018, my brother and sister-in-law took me sight-seeing to the northern parts of Israel near the Sea of Galilee. On our first night, we stayed at the home of one of their older friends, a man in his seventies.

That night we sat around their kitchen table so that they could catch up on family matters. At one point in the conversation our host reminisced about an older woman, now gone, who he had known in his childhood in the 1950s who had lived in Germany before and during World War II and had survived a concentration camp.

Isaacman: SLS stands on very thin ice

2:46 pm

Though NASA administration Jared Isaacman continues to support unequivocally NASA’s planned Artemis-2 ten-day manned mission around the Moon — presently targeting a March launch date — in a statement today on X he revealed that he also recognizes the serious limitations of the SLS rocket.

And it takes two-plus years between launches
And it also takes two-plus years between launches

The Artemis vision began with President Trump, but the SLS architecture and its components long predate his administration, with much of the heritage clearly traced back to the Shuttle era. As I stated during my hearings, and will say again, this is the fastest path to return humans to the Moon and achieve our near-term objectives through at least Artemis V, but it is not the most economic path and certainly not the forever path.

The flight rate is the lowest of any NASA-designed vehicle, and that should be a topic of discussion. It is why we undertake wet dress rehearsals, Pre-FRR, and FRR, and why we will not press to launch until we are absolutely ready.

These comments were also in connection with the first wet dress rehearsal countdown that NASA performed with SLS/Orion in the past few days, a rehearsal that had to be terminated early because of fuel leaks. NASA now plans to do another wet dress rehearsal, requiring it to push back the Artemis-2 launch until March.

I think there is more going on here than meets the eye.

India schedules next PSLV launch for June, claims it knows cause of January launch failure

9:10 am

India's space agency ISRO, as transparent as mud
India’s space agency ISRO,
as transparent as mud

According to a statement by a government minister yesterday, India’s space agency ISRO now knows what caused the January launch failure of its PSLV rocket, and has thus scheduled its next launch for June 2026.

This had been the second PSLV launch failure in a row, both of which occurred with the rocket’s third stage at almost the exact same time. With the first failure, ISRO never outlined publicly the cause, though it claimed it had solved the issue. According to the minister’s statement, the failure of the second launch was unrelated to the first.

The minister also said that the two PSLV missions that had failed—PSLV-C61 in May 2025 and PSLV-C62 in January this year—were unrelated. “It wasn’t the same problem. When the first mission failed, there was a detailed assessment, and the problem was fixed. Both the issues were different,” Singh said.

He also added that separate internal and external failure assessment committees have been set up to analyse what went wrong in each of the missions.

No word however as to the cause of the failure has yet been released. Though he also claimed the PSLV has not lost its customers due to these issues, ISRO’s lack of transparency says otherwise. If it claims the two failures came from different causes, it should provide the details in order to reassure potential customers.

NASA makes right decision and delays Artemis-2 launch to do a 2nd dress rehearsal countdown

8:53 am

Artemis Program logo

NASA management announced today that it has decided to postpone the launch of the manned Artemis-2 mission around the Moon until March in order to give it time to do a second wet dress rehearsal countdown of the rocket and fix the hydrogen fuel leaks that occurred in yesterday’s rehearsal.

Engineers pushed through several challenges during the two-day test and met many of the planned objectives. To allow teams to review data and conduct a second wet dress rehearsal, NASA now will target March as the earliest possible launch opportunity for the flight test.

Moving off a February launch window also means the Artemis II astronauts will be released from quarantine, which they entered in Houston on Jan. 21. As a result, they will not travel to NASA’s Kennedy Space Center in Florida Tuesday as tentatively planned. Crew will enter quarantine again about two weeks out from the next targeted launch opportunity.

It should be understood that these hydrogen leaks have been systemic to SLS’s core stage rocket engines, which come from the shuttle era. Shuttle launches were routinely delayed due to similar leaks. This was partly because hydrogen is extremely difficult to control, as its atom is so small and light, and partly because of the engine design. This was the first rocket system ever to use hydrogen as fuel, and was thus cutting edge, in the 1970s. We should not be surprised by such issues.

Newer hydrogen-fueled designs have apparently overcome the problem. For example, Blue Origin uses hydrogen as a fuel in the upper stage of its New Glenn rocket, and though it has only launched twice, it has not had such issues on either launch.

In its announcement NASA also noted a bunch of other issues that occurred during this first rehearsal, all of which suggest that a delay is called for. There was a valve issue in the Orion capsule, some audio communication channels kept dropping out, and the cold weather affected some equipment. Waiting until warmer weather will help alleviate some of this.

Fuel leaks cause Artemis-2 dress rehearsal countdown to terminate at T-5:15, several minutes early

11:15 pm

Artemis Program logo

Two hydrogen fuel leaks during today’s Artemis-2 dress rehearsal countdown forced an early termination of the count as well as the cancellation of a second practice countdown.

The Artemis II wet dress rehearsal countdown was terminated at the T-5:15 minute mark due to a liquid hydrogen leak at the interface of the tail service mast umbilical, which had experienced high concentrations of liquid hydrogen earlier in the countdown, as well. The launch control team is working to ensure the SLS (Space Launch System) rocket is in a safe configuration and begin draining its tanks.

An earlier leak of hydrogen in the count forced a hold and a recycling of the count, though it did not stop the rehearsal.

The initial plan had been to do two terminal counts. First they would run the countdown down to T-33 seconds, hold for a few minutes, then recycle back to T-10 minutes and do it again. Because of that first leak delay the launch director canceled the second count. And because of the second leak they were unable to run that one count all the way to T-33 seconds.

The wise action would be for NASA to review their data, figure out what caused the leaks, correct it, and then do another dress rehearsal countdown. This being NASA, do not be surprised if they review the data, figure out what caused the leaks, and decide they can go ahead with the launch on February 8, 2026.

Why not? They are already launching this manned 10-day mission around the Moon with an untested life support system and a questionable heat shield. Might as well try a launch when you haven’t worked out all the fueling kinks.

Axiom wins slot for next tourist mission to ISS

2:25 pm

NASA yesterday announced that it awarded the space station startup Axiom the next slot for a tourist mission to ISS.

NASA and Axiom Space have signed an order for the fifth private astronaut mission to the International Space Station, targeted to launch no earlier than January 2027 from the agency’s Kennedy Space Center in Florida.

…Axiom Mission 5 is expected to spend up to 14 days aboard the space station. A specific launch date will depend on overall spacecraft traffic at the orbital outpost and other planning considerations.

Both Axiom and the space station startup Vast had been bidding for the fifth and sixth tourist slots. That Axiom had already done this four times previously was probably NASA’s reasons for choosing it. The agency has not yet decided on who will get the sixth slot, targeting a mission likely in 2028. My bet is that it will give to Vast, because by then Vast’s own demo station Haven-1 will have launched and been visited, thus giving that company some of the experience Axiom already has.

Russia in discussions with Malaysian province about potential spaceport

1:49 pm

Proposed spaceports in Malaysia
Proposed spaceports in Malaysia

Officials from Glavcosmos, the commercial division of Russia’s Roscosmos space agency, have been holding meetings with officials from the Malaysian province of Sabah about building a spaceport there.

Glavkosmos said technical studies identify Sabah as the most suitable location in Southeast Asia for orbital launches, including low-earth and sun-synchronous orbits, due to its strategic geography and safe rocket stage drop zones. The proposed spaceport could create more than 2,000 high-income jobs and boost local supporting industries.

One year ago, in January 2025, the Sabah government announced it was holding similar discussions with the Ukraine. It seems either those talks fell through, or Russia decided to move in and block the Ukraine from making a deal.

A second Malaysian state, Pahang, is also planning a spaceport, working instead with China.

In all cases, it does appear for some reason Malaysia is not very interested in working with western nations.

Amazon asks FCC for time extension for launching its Leo constellation

11:22 am

Amazon yesterday submitted a request to the Federal Communications Commission to extend the July deadline on its license for its Leo internet satellite constellation, which presently requires it to have 1,616 satellites in orbit by that date.

At present Amazon has 181 satellites in orbit, all launched in the last ten months. At that pace there is no chance the company can meet its FCC requirement. From its FCC submission:

While Amazon Leo will meet the deadline for full deployment of its constellation established by its license and the Commission’s rules, launch delays will cause it to fall short of the interim milestone requirement to deploy half of its originally authorized constellation by July 30, 2026. The Commission’s rules provide for extension of such milestones where, as here, delay arises from unforeseeable circumstances beyond an operator’s control or overriding public interest considerations favor an extension.

Because it meets both criteria, Amazon Leo respectfully requests a 24-month extension of its 50% milestone to July 30, 2028, or alternatively, a waiver of this interim requirement.

In its submission Amazon claims the delay is entirely the fault of the rocket companies it was relying on to launch the satellites, but that is a bogus claim. It initially choose to depend almost entirely on three new rockets (Blue Origin’s New Glenn, ULA’s Vulcan, and Arianespace’s Ariane-6), all of which had not launched and were still under development. To expect these to launch on time was absurd.

Furthermore, its ULA contract also called for launches using company’s already operational Atlas-5 rocket, which Amazon claims were delayed because of “unexpected anomalies and delays caused by issues with its vehicle fairings and solid rocket boosters.” I don’t buy it, and suspect the real cause was that Amazon was unable to produce the satellites on time.

Faced with these delays and a stockholder lawsuit, Amazon subsequently signed SpaceX to do three launches, which that company did quickly, in less than four months. If Amazon had truly wanted to get its Leo satellites in orbit on time, it would have given SpaceX more launches and gotten it done.

Nonetheless, it is likely the FCC will agree to Amazon’s extension request. The company has now shown it is committed to the process and intends to get its constellation in orbit. It is not sitting on its license doing nothing. I would not be surprised however if the FCC imposes some new requirements in an effort to force Amazon to launch more satellites more quickly.

China launches Algerian satellite

10:23 am

China today successfully placed an Algerian “remote sensing” satellite into orbit, its Long March 2C rocket lifting off from its Jiuquan spaceport in northwest China.

No word on where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China. China’s state-run press also said little about the satellite, other than claiming it would be used for “land planning and disaster prevention and mitigation.” This however doesn’t match what “remote sensing” satellites usually do, which is military surveillance.

Russian defunct military satellite breaks up in graveyard orbit

1:42 pm

A Russian defunct military geosynchronous satellite that was launched in 2014 and spent a decade spying on other geosynchronous satellites only to be moved to a graveyard orbit in 2025 when its fuel ran out apparently broke apart earlier today.

The Swiss company S2A systems, which specializes in tracking orbital objects, captured the moment the spacecraft began disintegrating. I have embedded that footage below, though it really is far less exciting than it sounds.

The debris poses a very small risk to other geosynchronous satellites, which orbit at about 22,000 miles elevation where there is too little atmosphere to decay orbits. The graveyard orbit is several hundred miles higher.

FAA moves forward on its environmental assessment of SpaceX’s proposal to launch Starship/Superheavy from Kennedy Space Center

12:01 pm

Proposed Starship/Superheavy launchsites at Kennedy and Cape Canaveral
Proposed Starship/Superheavy launchsites at
Kennedy (LC-39A) and Cape Canaveral (SLC-37)

While NASA has already determined that Starship/Superheavy launches from the Kennedy Space Center in Florida will have no significant impact on the environment, the FAA has not yet completed its own environmental impact statement.

Last week it released a preliminary summary [pdf] of its impact statement, revealing that it has reduced its final options to either approving SpaceX’s request to do as many as 44 launches per year, or to reject any changes — the “no action alternative” — which would block all Starship/Superheavy launches at Kennedy.

The overall tone of this summary suggests strongly that the FAA is almost certainly going to approve SpaceX’s request, allowing as many as 44 launches per year from launchpad LC-39A, as shown on the map to the right. As it notes in describing the “no action alternative”:

SpaceX would not launch Starship-Super Heavy from LC-39A. NASA would not develop, implement, or approve agreements with SpaceX associated with Starship-Super Heavy operations at LC-39A. The No Action Alternative would not meet the purpose and need. [emphasis mine]

In other words, rejecting SpaceX’s request would not fulfill the FAA’s obligation to serve the public. It would also not fulfill the FAA’s obligation to serve a fellow government agency, NASA, which has already approved this SpaceX request in a 2019 environmental assessment.

It appears a final decision by the FAA is imminent. A nice summary of this FAA document can be found here, which notes that if approved, it will give SpaceX license approval to launch Starship/Superheavy as much as 146 times per year, from its launchpads at Boca Chica, Kennedy, and Cape Canaveral. Note too that this FAA assessment is independent of the Air Force’s environment assessment, which has already approved 76 launches per year at the SLC-37 launchpad.

Orbex failure occurred partly because UK government withheld promised funding

10:34 am

Prime rocket prototype on launchpad
The prototype of Orbex’s never-launched Prime rocket,
on the launchpad in 2022

It appears the government of the United Kingdom contributed to the bankruptcy and sale of the British rocket startup Orbex in more than one way.

Orbex had hoped to do its first launch from the proposed Sutherland spaceport on the north coast of Scotland in 2022, but was blocked for four years because of red tape. First, the UK’s Civil Aviation Authority would not issue the spaceport and launch licenses. Second, local opposition delayed approvals as well. Those delays ate into the company’s resources, until it became entirely dependent on grants from the UK government (some through the European Space Agency) to keep it afloat.

Orbex’s problems were further compounded when it became clear in 2024 that the Sutherland spaceport would never get clearance. Orbex then switched to the Saxavord spaceport in the Shetland Islands, but this forced more delays because the company had no facilities there. It had already spent a fortune building everything for Sutherland.

A new report today says that it was finally forced to shut down and sell its assets to the French startup The Exploration Company because the UK government had withheld some of that promised funding.

News of the potential sale came just a month after a European Space Agency document confirmed that €112 million of €144 million UK government funding, earmarked for the European Launcher Challenge (ELC) scheme, was still “to be distributed”.

As a result, Orbex received just €34.9 million from the scheme – one-fifth of the €169 million awarded to each of its rivals by European governments.

That shortfall equates to about $160 million, a substantial amount of cash. While it is perfectly reasonable for the UK government to withheld these funds if it thinks the money would be badly spent, none of this government funding would not have been necessary at all if the UK government had simply issued the launch permits in a timely manner, allowing Orbex to launch and earn revenue.

As I noted early, congratulations to the United Kingdom, the place where rocket companies go to die! This is now the second such company killed by UK red tape and government incompetence, the first being Virgin Orbit.

Russian official says Soyuz launchpad repair likely delayed

9:48 am

According to the Russian official in charge of ground infrastructure at Roscosmos, the repair of Russia’s only Soyuz launchpad for launching Progress and Soyuz capsules to ISS might not be completed by late March, as Roscosmos has previously promised.

It appears the winter weather at Baikonur is causing issues. In addition:

Barmin explained that the new service platform had to be assembled from components manufactured at different times and sometimes mismatching each other, requiring on-site modifications. For example, the core of the spare platform was manufactured in 1977 in accordance with a different set of blueprints for a planned-but-never-implemented refurbishment of another Soyuz pad, Barmin said. When it was shipped from an arsenal in the city of Tambov to Baikonur, the set of hardware was incomplete, requiring it to be complemented with parts from other sources and with newly manufactured elements.

It also appears the Russian government is going to make scapegoats of the workers who handled the launch platform during the November 2025 launch. It has placed them under criminal investigation. The managers, whom according to one report demanded the launch take place even though these workers could not get the platform properly fastened in place, appear to have been cleared of wrong-doing.

Until this pad is repaired, Russia has no way to launch any manned missions. Nor can it send cargo to ISS.

The decision to scapegoat the workers will further hinder work, as it will certainly damage morale. Such an approach also helps explain why there has been several cases of sabotage of Soyuz and Progress capsules while they are being prepped for launch.

NASA delays Artemis-2 wet dress rehearsal countdown due to weather

9:30 am

NASA today announced it is delaying until February 2, 2026 the wet dress rehearsal countdown of its Artemis-2 mission due to weather concerns.

NASA is targeting Monday, Feb. 2, as the tanking day for the upcoming Artemis II wet dress rehearsal at the agency’s Kennedy Space Center in Florida, as a result of weather. With this change, the first potential opportunity to launch is no earlier than Sunday, Feb. 8.

Over the past several days, engineers have been closely monitoring conditions as cold weather and winds move through Florida. Managers have assessed hardware capabilities against the projected forecast given the rare arctic outbreak affecting the state and decided to change the timeline. Teams and preparations at the launch pad remain ready for the wet dress rehearsal. However, adjusting the timeline for the test will position NASA for success during the rehearsal, as the expected weather this weekend would violate launch conditions.

I had previously said this dress rehearsal countdown would include the astronauts inside Orion. This was incorrect. The astronauts are in quarantine in preparation for the actual mission. Orion will be unmanned during the rehearsal countdown.

Varda capsule successfully returns to Earth after nine weeks in orbit

9:36 pm

Varda's W-5 capsule after landing today
Varda’s W-5 capsule after landing today

The orbiting capsule startup Varda today successfully returned to Earth its W-5 capsule after nine weeks in orbit, landing in Australia’s Koonibba Test Range, operated by the commercial spaceport startup Southern Launch.

W-5 launched in November 2025, Varda’s fourth launch last year, and spent 9 weeks in orbit. The mission was funded through the Prometheus program, a partnership between the Air Force Research Laboratory (AFRL) and commercial space entities.

…The W-5 mission is the first reentry of Varda’s in-house developed satellite bus, designed specifically to meet the rigorous demands of both long-duration orbital pharmaceutical processing and high-velocity reentry. The W-5 flight was also equipped with an in-house manufactured heatshield, made in Varda’s El Segundo headquarters from C-PICA (Conformal Phenolic Impregnated Carbon Ablator).

…The W-5 capsule carried a specialized payload for the U.S. Navy, focusing on data collection during reentry. Varda’s ability to provide fixed-cost, routine reentry offers the Department of War a unique, cost-effective platform for iterative testing of hypersonic flight characteristics. The Varda capsules endure extreme environments when they reenter at speeds exceeding Mach 25.

While previous capsules had used their time in orbit testing the manufacture of products like pharmaceuticals, this mission was used by the Air Force to test hypersonic missile sensors and equipment during the high-speed re-entry.

Varda’s earlier capsules had used a satellite bus (that provides power and control) built by Rocket Lab. With this capsule it is now capable of building its entire capsule. It is also ramping up its launch pace, with plans to launch as many as 20 capsules through ’28.

Artemis-2 proves NASA learned nothing from the Challenger and Columbia failures

9:56 am

NASA: an agency still avoiding reality
NASA: an agency that still avoids reality

Our bankrupt new media continues to fail us. NASA is about to send four astronauts on a ten-day mission around the Moon in a capsule with questionable engineering, and that media continues to ignore the problem. Mainstream news outlets continue to describe the mission in glowing terms, consistently ignoring that questionable engineering. In some cases the stories even make believe NASA has fixed the problem, when it has not.

The most ridiculous example is an article yesterday from an Orlando outlet, Spectrum New 13: “How the lessons learned from the Challenger disaster apply to Artemis rockets”. It focuses entirely on the O-ring problem that destroyed Challenger, noting repeatedly that NASA has fixed this issue in its SLS rocket.

Of course it has. That’s the last war, long over. Engineers fixed this issue almost four decades ago. The article however dismisses entirely the new engineering concern of today, Orion’s heat shield, which did not work as expected during its own test flight in space in 2022. It covers this issue with this single two-sentence paragraph:

However, during re-entry, it broke up into chunks instead of burning away. This issue pushed back the Artemis II and III missions, but NASA has stated it has resolved the problem.

NASA however has not resolved the problem. It is using the same heat shield now on this manned mission, and really has no reason to assume it will work any better, even if the agency has changed the re-entry flight path in an effort to mitigate the heat shield’s questionable design.

You see, NASA with Artemis-2 is doing the exact same thing it did prior to both the Challenger and Columbia accidents. » Read more

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

10:06 am

aerospike engine in October 2024.

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.

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

5:23 pm

Europa in true color
Europa in true color, taken by Juno during that
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.

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

8:25 am

The flight plan for the Artemis-2 mission around the Moon
The flight plan for the Artemis-2 mission around the Moon. Click for original.

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.

NASA makes it official: Oman signs the Artemis Accords

Active and proposed Middle East spaceports
Active and proposed Middle East spaceports

In a press announcement yesterday, NASA officially confirmed that Oman has become the 61st nation to sign the Artemis Accords.

U.S. Ambassador to the Sultanate of Oman Ana Escrogima and NASA’s Deputy Associate Administrator Casey Swails participated in the event held on the opening day of the Middle East Space Conference, an international forum on space and innovation in the region. Said al-Maawali, Oman’s minister of transportation, communication, and information technology signed on behalf of the country.

I had reported early yesterday a story in Oman’s state-run press claiming that its sultan wanted his country to sign the Artemis Accords, a claim put forth by Oman officials during this conference. Apparently that was poor reporting. What actually happened was the event included the official Artemis Accords signing ceremony, which also included a number of other bi-laterial trade agreements.

As I noted yesterday, Oman has been unsuccessful so far in its efforts to bring American rocket and satellite companies to its proposed Duqm spaceport because State Department ITAR regulations, designed to protect American technology from hostile foreign powers, prevent it. This agreement hopefully includes some security guarantees that will ease those regulations and allow such deals.

Oman’s proposed spaceport at Duqm.

In a diplomatic meeting between Oman and U.S. state department in Oman, Oman officials announced their Sultan wants his country to sign the Artemis Accords.

The two sides discussed means of maximising the benefits of the Free Trade Agreement between the two countries and augmenting American investments in sectors of priority for the Sultanate of Oman. These sectors include the digital economy, technology and space, in addition to mining, logistics, aviation and infrastructure.

Cooperation in the fields of education and culture was also discussed, particularly educational programmes, academic and professional exchange and investment in research and innovation. The two sides further exchanged views and positions on a number of regional and international issues, emphasising the importance of backing efforts for peace, stability and development.

During the dialogue, the Omani side announced the Sultanate of Oman’s approval to join the ‘Artemis Accords’ for space exploration. A cooperation statement on the 250th anniversary of the founding of the United States of America was also signed. [emphasis mine]

Much of this is diplomatic blather, meaning little. While I would expect the Trump administration welcome Oman as an Artemis Accord partner, in the talks related to the highlighted first paragraph above it likely demanded some concessions first. Free trade in Oman is going to require some protection for American technology.

For example, right now State Department rules make it difficult if not impossible to launch American satellites or rockets from Oman’s proposed spaceport in Duqm, rules imposed because Oman cannot be trusted. I expect the State Department is demanding total security control from U.S. entities on any launch before agreeing to an Oman Artemis Accord agreement.

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

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.

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.

Orbex’s Danish subsidiary to file for bankruptcy

8:30 am

In what appears to confirm the story yesterday that the rocket startup Orbex was about to be bought out by the French startup The Exploration Company — thus likely ending operations in Great Britain — there was a second follow-up story later in the day that claimed Orbex’s Danish subsidiary is about to file for bankruptcy.

On 20 January, more than 15 Orbital Express Launch ApS employees announced at around the same time on LinkedIn that they were looking for work. Since then, European Spaceflight has received confirmation from three independent sources, who wished to remain anonymous, that the subsidiary has dismissed its entire workforce, with the company expected to officially file for bankruptcy on 22 January.

The article notes that this subsidiary had been losing millions in the past two years, and was entirely reliant on cash from its parent company. Unfortunately, Orbex has had no incoming revenue itself, because red tape in the United Kingdom had prevented it from launching for the past four years.

If true, this story confirms that Orbex’s negotiations with The Exploration Company is likely an attempt to make as much money from its remaining assets as possible before closing down.

Congratulations to the United Kingdom, the land where rocket companies go to die!

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

8:01 am

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.
