A sinuous ridge of uncertain origin
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on July 21, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It was posted today by the camera team as a captioned image, with the caption as follows:

The sinuous ridge is approximately 10 meters wide and several kilometers long. The floor surrounding this ridge has been eroding laterally, forming pits and circular features suggestive of removal (sublimation) of subsurface ice. However, landforms such as channels or moraines that might suggest the presence of water or ice are lacking, so the ridge itself does not appear to have formed by fluvial or glacial processes.

Perhaps this curious feature is an exhumed dike formed from magma emanating from Alba Mons in subsurface fractures.

Alba Mons is a gigantic shield volcano to the west.

Rocket Factory Augsburg getting close to launch

9:16 am

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

The German rocket startup Rocket Factory Augsburg appears to finally be getting close to launching its RFA-1 rocket after a static fire test explosion in 2024 seriously delayed its plans.

Speaking to European Spaceflight in early February, Rocket Factory Augsburg CEO Prof. Dr. Indulis Kalnins, who replaced Dr. Stefan Tweraser in April 2025, explained that the rocket’s first stage is in the process of being transported from Augsburg in Germany to the launch site on Unst. The rocket’s upper stage, which has received upgrades to its single Helix engine and the associated control software, is expected to follow in the next few weeks.

On 10 February, the company announced that the new umbilical tower had been raised, standing at 52 metres high. The tower will support and stabilise the rocket and provide propellant, power, and data connections. The company has begun commissioning the repaired and upgraded launch pad. The only element still to be added is the water tanks for the water deluge system. Kalnins, however, stressed that the company is taking its time with all pre-flight testing.

It appears my speculation that the company had not yet received its launch licenses from the Civil Aviation Authority (CAA) was wrong. Those licenses were issued in January 2025, only five months after the static fire launchpad explosion. For the CAA to respond that quickly is quite surprising. Maybe it decided it shouldn’t kill a third rocket company trying to launch from the UK.

Right now the race to be the first orbital rocket launched from a European spaceport is coming down to Rocket Factory and its German competitor Isar Aerospace. Isar is gearing up to make its second attempt to launch its Spectrum rocket from Norway’s Andoya spaceport in March.

Fairing from India’s Bahubali rocket launched in December found in Maldives

9:00 am

A man fishing off an uninhabited island in the Maldives discovered what appears to be pieces from the fairing used by India’s LVM3 rocket, also dubbed Bahubali, when it launched AST SpaceMobile’s sixth Bluebird satellite in December.

A similar discovery was made on December 28, 2025 in Sri Lanka. In both cases it is theorized that the material came from the fairings of the December Bahubali launch.

I am unable to determine the flight path of the Bluebird launch, but the location of this debris suggests it headed strongly south from India’s east coast spaceport. The fairing pieces then drifted south and west to reach the Maldives after two months.

SpaceX routinely recovers its fairing and resuses them, which due to the fairing’s basic shape has turned out to be relatively straightforward. They have the shape of a boat’s hull, and after parachuting softly down can simply float on the surface until they can be picked up. It is absurd no one else does this.

SpaceX launches 29 Starlink satellites

8:42 am

SpaceX in the early morning hours today successfully launched another 29 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its 10th flight, landing on a drone ship in the Atlantic.

The 2026 launch race:

19 SpaceX
8 China
2 Rocket Lab
2 Russia
1 ULA
1 Europe (Arianespace)

As it did in both ’24 and ’25, SpaceX in ’26 so far has more launches than the entire rest of the world combined.

Chinese pseudo-company raises $729 million

10:35 pm

The Chinese pseudo-company rocket startup Ispace announced on February 13, 2026 that it has raised $729 million in new investment capital.

Beijing Interstellar Glory Space Technology Ltd., also known as iSpace, announced the D++ funding worth 5.037 billion yuan Feb. 12, following a D+ round of $98 million (700 million yuan) in September 2025. The round appears to be the largest disclosed funding round so far for a Chinese launch startup, eclipsing the previous rounds secured by Space Pioneer ($350 million) and Galactic Energy ($336 million) in 2025.

A press statement outlines a hybrid syndicate of numerous funding round participants, incgovernment industrial funds, state-linked strategic ecosystem investors, municipal and provincial investment vehicles and private equity. This follows a trend of strong strategic investment in space companies in China over the past couple of years since the central government identified commercial space as a strategic emerging industry and key driver of high-tech development. Co-leads Tongchuang Weiye and existing shareholder Jingming Capital represent market-oriented investors focused on advanced manufacturing and aerospace, and were joined by repeat backing from private equity players such as CDH Baifu and Ganquan Capital. [emphasis mine]

It is hard to determine how independent these Chinese investment firms are from the government. I suspect the communists are closely involved in some manner or another.

The press release made no mention of a timeline for when Ispace will attempt the first launch and recovery of its Hyperbola-3 rocket. It had previously targeted a 2025 launch, but that never happened.

NASA testing SLS fuel leak repairs; UPDATE: Problems!

10:33 am

UPDATE: NASA posted a late update today describing vaguely the results of this fueling test, and revealed that while the test of the replacement seals appeared to go well, there were other problems:

During the test, teams encountered an issue with ground support equipment that reduced the flow of liquid hydrogen into the rocket. … Engineers will purge the line over the weekend to ensure proper environmental conditions and inspect the ground support equipment before replacing a filter suspected to be the cause of the reduced flow.

In other words, the SLS fueling system is like playing whack-a-mole. You fix one problem, and others show up.

I predicted this. It remains entirely possible NASA will not be able to complete a perfect full wet-dress rehearsal countdown in time to launch before April 6th, when this present launch window closes.

Original post:
———————-
NASA yesterday did an unannounced test fueling of its SLS rocket to check out the repairs in the fueling system.

NASA is loading liquid hydrogen aboard its Space Launch System moon rocket at the Kennedy Space Center on Thursday for an unpublicized but crucial test of the repairs made to a leaky umbilical that derailed a countdown rehearsal on Feb. 2.

The operation to load liquid hydrogen into the huge fuel tank on the rocket’s core stage was thought to be already underway at launch complex 39B on Thursday morning. The test will determine if new seals installed in the launch pad umbilical are working. “As part of our work to assess the repair we made in the area where we saw elevated hydrogen gas concentrations during the previous wet dress rehearsal, engineers are testing the new seals by running some liquid hydrogen across the interface and partially filling the core stage liquid hydrogen tank. The data will inform the timeline for our next wet dress rehearsal,” a NASA spokesperson said about the previously unannounced test.

If the new seals work on these fueling tests, another full dress rehearsal countdown could take place as early as next week.

Posting is going to very light for the rest of the day. I am fighting a bad head cold and just want to go back to bed.

FAA confirms “no significant impact” to environment for Starship/Superheavy at Boca Chica

9:42 am

The FAA today released [pdf] its final environmental assessment reviewing SpaceX’s request to expand operations of Starship/Superheavy at Boca Chica, confirming that it has determined there will be “no significant impact” to environment.

The 2022 PEA and April 2025 Tiered EA examined the potential for significant environmental impacts from Starship-Super Heavy launch operations at the Boca Chica Launch Site and defined the regulatory setting for impacts associated with Starship-Super Heavy. The areas evaluated for environmental impacts in this Tiered EA include noise and noise‐compatible land use; aviation emissions and air quality; hazardous materials, solid waste, and pollution prevention; and socioeconomics. In each of these areas, the FAA has concluded that no significant impacts would occur as a result of the Proposed Action.

The approval will allow SpaceX to do 25 launches per year (three of which are at night). The approval also appears to lay the groundwork for bringing Superheavy back not only to Boca Chica, but to Florida. It also lays the groundwork for bringing Starship back to Boca Chica after completing an orbital flight, to be caught by the tower chopsticks.

Vast wins sixth ISS slot for tourist mission

5:11 pm

Haven-2
Vast’s full Haven-2 station once completed

NASA today announced that it has awarded the space station startup Vast its sixth slot for a manned commercial mission to ISS, scheduled for 2027.

The mission 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.

…Vast will submit four proposed crew members to NASA and its international partners for review. Once approved and confirmed, they will train with NASA, international partners, and SpaceX for their flight. The company has contracted with SpaceX as launch provider for transportation to and from the space station.

Vast already intends to fly four two-week missions to its single module Haven-1 demo station, scheduled to launch in the first quarter of 2027. This new ISS mission will demonstrate to NASA directly that Vast can handle manned missions. In both cases, the company is hoping its actions will convince NASA to award it a full construction contract to build its Haven-2 full-sized station, as shown in the graphic to the right.

Below are my rankings of the five private commercial space stations being developed. At this point the first three (Haven, Axiom, Starlab) are essentially tied, while the fourth (Thunderbird) is only trailing because it came late to the game. The fifth, Orbital Reef, seems practically out of the game.

New Zealand raises its annual cap of rocket launches from 100 to 1,000

10:28 am

The New Zealand government has now increased the number of launches it will allow from within its territory each year from 100 to 1,000.

The government is raising the total number of launches allowed to 1000, as the cap set at 100 in 2017 comes close to being breached. The US-NZ company Rocket Lab dominates the launch market from its pad at Mahia.

Space Minister Judith Collins said the 100 cap was likely to be hit this year. “This change ensures our space and advanced aviation industries can continue to expand while operating within clear environmental boundaries.” The environmental impact from more debris from space vehicle launches had been newly determined to be low.

The rules would have required a special marine consent for every launch over the 100 cap.

The article at the link is a typical leftist anti-achievement propaganda piece, spending more time airing the complaints by one physics professor than reporting the details of this new ruling. Nonetheless, this decision will likely benefit Rocket Lab’s operations significantly, as it hopes this year to make as many as two launches per month. While that remains below the old 100 launch cap, the new 1,000 launch cap gives it a limit it won’t face for decades, if ever.

It will also likely benefit several spaceports to the west in Australia. Some of their launches would likely need New Zealand clearance, and this new limit will ease their regulatory burden.

Four launches today with mostly positive results

10:15 am

This morning saw a string of launches from China, Russia, America, and Europe, with all four appearing to get their payloads into orbit though the American launch, by ULA’s Vulcan rocket, appeared to have a problem with one of its solid-fueled boosters.

First, a Chinese pseudo-company owned entirely by a Chinese government agency successfully placed seven satellites in orbit, its Smart Dragon-3 rocket (also called Jielong-3) lifting off from a platform off the coast of northeast China. Of the satellites, the prime payload was a Pakistani Earth observation satellite.

Though this launch was from a pseudo-company, I think I can safely say that the pause in launches by China’s so-called commercial market continues. Smart Dragon-3 was built by the China Aerospace Science and Technology Corporation (CASC), which while structured as a private company is owned and controlled by several agencies of the Chinese government.

Next, Russia successfully launched a new weather satellite, its Proton rocket launching from Baikonur in Kazakhstan. This was the first Proton launch in three years, a pause partly because Russia is in the process of retiring that rocket. The lower stages crashed in a range of spots in Kazakhstan and across southern Russia, just missing China in two places.

The American company ULA then followed with its first launch in 2026, its Vulcan rocket lifting off from Cape Canaveral in Florida and carrying two military satellites designed to track other satellite operations in high geosynchronous orbit.

Unexpected debris falling from rocket at about T-1:00
Unexpected debris falling from rocket at about T-1:00

While it appears the launch was able to get the satellites into their correct orbits, the Vulcan rocket had an issue during the launch. According to ULA, one of the rocket’s four solid-fueled boosters had a problem during its flight. More details can be found here, suggesting the booster, built by Northrop Grumman, might have had a been a failure of the booster’s nozzle, similar to the same burn-through that occurred on a booster during Vulcan’s second launch in 2024, and also occurred during a Northrop Grumman static fire test in 2025.

This issue is likely going to delay further Vulcan launches, and will likely make it impossible for ULA to meet its goal of launching 16 to 18 Vulcan missions this year. It will also raise hackles within the Pentagon, which certified Vulcan for military launches in 2025. That certification will likely be questioned, and possibly even pulled.

Finally, Arianespace sent 32 Leo satellites into orbit for Amazon, its Ariane-6 rocket lifting off from French Guiana. This was the first Ariane-6 launch in its most powerful variant, using four strap-on boosters.

Amazon has now launched 212 Leo satellites. Its FCC license however requires it to have 1,616 in orbit by July. The company has requested a waiver on that requirement, and is likely to get it, since it is now demonstrating that it is serious about launching the constellation.

The 2026 launch race:

16 SpaceX
8 China
2 Rocket Lab
2 Russia
1 ULA
1 Europe (Arianespace)

British rocket startup Skyrora might buy Orbex assets

9:24 am

The British rocket startup Skyrora, which has been around since 2018 and has yet to complete an orbital launch, today indicated it might buy the remaining assets of the now bankrupt British rocket startup Orbex.

The company, which has a manufacturing facility in Cumbernauld, said its move would ensure Orbex technology and the spaceport remained under UK ownership. It also said its bid would safeguard products that had received public funding.

Skyrora has been making promises for almost a decade with no clear progress. It did two successful suborbital tests in 2020 (here and here), had a failed suborbital test in 2022, and applied for an orbital launch license with Britain’s Civil Aviation Authority (CAA) in January 2024. Not surprisingly, it is unclear whether that license has been approved. The company said last year it wants to do that orbital launch in ’26 from the Saxavord spaceport in the Shetland Islands. That gives the CAA two years to approve the license, which based on that agency’s track record might be enough time to get the job done. Or not.

Getting Orbex’s assets might actually be a good thing for Skyrora, which has not been very successful getting anything going with its own engineering. It will still face that odious regulatory regime of the United Kingdom, that has now killed two different rocket startups.

Engineers have shut down the Gehrels-Swift space telescope in a last attempt to save it

8:07 am

Katalyst's proposed Swift rescue mission

Click for original image.

In order to delay the moment the orbit of the Gehrels-Swift Observatory decays — to increase the chance a rescue mission can get there in time — engineers have now stopped almost all scientific observations temporarily.

On Feb. 11, NASA’s Neil Gehrels Swift Observatory temporarily suspended most science operations in an effort to reduce atmospheric drag and slow the spacecraft’s orbital decay. Halting these activities will enable controllers to keep the spacecraft in an orientation that minimizes drag effects, extending its time in orbit in anticipation of a reboost mission.

“Normally, Swift quickly turns to view its targets — especially the fleeting, almost daily explosions called gamma-ray bursts — with multiple telescopes,” said principal investigator S. Bradley Cenko at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Swift’s Burst Alert Telescope will continue to detect gamma-ray bursts, but the spacecraft will no longer slew to observe targets with its other telescopes.”

…To maximize the orbit boost’s chances of success, Swift’s average altitude needs to be above about 185 miles. As of early February, Swift’s average altitude had fallen below about 250 miles.

NASA has awarded the orbital repair startup Katalyst the contract to rescue Gehrels-Swift, but the company has a very challenging mission. It got the contract only a few months ago, in September 2025, and is refitting its planned satellite rescue demo mission to save the space telescope instead. The graphic to the right shows how its rescue robot will approach and grab Gehrels-Swift to raise its orbit, but it must be noted that the telescope has no planned grapple points, and Katalyst’s robot has never done this before.

Moreover, the robot will be launched using the last Pegasus rocket in Northrop Grumman’s warehouse, with a launch scheduled now for sometime this summer. That means Katalyst has had to go from contract award to launch in less than a year, a pace that up until now has been unheard of in the space business. If successful however Katalyst will once again demonstrate the benefits of the capitalism model, whereby NASA buys the product from the private sector rather than building it itself. Left to NASA, this rescue mission would never happen.

And even if Katalyst’s rescue fails, that the company could get it built and launched in such a short time still proves the value of the capitalism model. Freedom and capitalism and competition at least made the attempt possible.

SpaceX completes extensive tank tests on next Superheavy booster

1:05 pm

Link here. The story details the repeated tank tests just completed on Superheavy booster prototype #19, intended to fly on the 12th Superheavy/Starship test flight now targeting a mid-March launch.

The article also describes the extensive repairs and upgrades to the Massey test stand facility following the explosion during a static fire test in 2025.

It does appear that the issues that caused the two recent blow-outs of Superheavy boosters in the past few months have been fixed, and that flight testing will resume in about a month.

A sculptured Martian landscape

Weird Martian landscape
Click for original.

Cool image time! The picture to the right, cropped and sharpened to post here, was taken on December 4, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this landscape “olivine-rich plains”, which is a magnesium iron silicate mineral of some industrial value that is quite common on Earth. Its presence here suggests there could be other valuable minerals in this region.

I post the image because the landscape is so weird and beautiful. The orange color suggests these ridges are covered with dust, if not made of dust entirely. The small areas with a greenish tint that appear to mostly appear on north-facing cliffs could be frost, except this is in the southern hemisphere where north-facing cliffs get more sunlight. As it was autumn when this picture was taken frost is an unlikely explanation.

More likely the green indicates exposures of bedrock or coarser boulders.

SpaceX launches 24 more Starlink satellites

10:17 am

SpaceX today successfully launched another 24 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.

The first stage completed its third flight, landing on a drone ship in the Pacific.

The 2026 launch race:

16 SpaceX
7 China
2 Rocket Lab
1 Russia

These numbers will definitely change in the next 24 hours, as there are launches planned from China, Russia, Europe, and ULA tomorrow, and a SpaceX Dragon manned launch to ISS the next day.

ULA’s new management predicts it will achieve 18-22 launches in 2026

10:03 am

Before Tory Bruno resigned as CEO of the United Launch Alliance (ULA) to go work for Blue Origin, he had predicted in August last year that ULA was primed to complete two launches per month for the rest of ’25 and throughout ’26.

That prediction did not happen, as the company was only able to do four launches in the last five months of 2025, and no launches so far in 2026.

Yesterday the new management of ULA insisted that Bruno’s prediction was still reasonable, and that the company will complete between 18 to 22 launches before the end of this year.

Speaking during a virtual media roundtable on Feb. 10, Gary Wentz, ULA’s vice president of Atlas and Vulcan Programs, said the company aims to launch two to four Atlas 5 missions and 16 to 18 Vulcan missions. He said the Vulcan rockets will be split between pad 41 at Cape Canaveral Space Force Station and pad 3 at Vandenberg Space Force Base. “It’s a balance. We’re working with our customers to determine specific priorities and order of missions and in the case of Space Force and NRO (National Reconnaissance Office), to determine which missions they wan to get off with higher priority,” Wentz said. “And as we finalize that over the next about six to eight months out of the mission, then we’ll assign whether or not its going to be an Atlas mission or a Vulcan mission.”

John Elbon, the interim CEO following the departure of Tory Bruno in December, said that the company has a “strong commitment” from their commercial and government customers, citing a backlog of more than 80 missions.

That backlog is mostly split between ULA’s big contract to launch Amazon’s Leo satellites and a variety of different agencies in the Pentagon. Both are desperate to get their satellites into space, and it appears ULA is struggling to figure out how to do it. In its early years (from 2007 to 2016) the company was generally able to average about one launch a month, but since then that launch rate as been less than half that. To not only return to those launch rates from a decade ago but to almost double them will be challenging, to say the least.

OHB Italia wins $96 million contract to build Ramses probe to visit the asteroid Apophis

9:39 am

Apophis' path past the Earth in 2029
A cartoon (not to scale) showing Apophis’s
path in 2029

The European Space Agency (ESA) yesterday announced that it has awarded the aerospace company OHB Italia a $96 million contract to build Ramses probe to rendezvous with the potentially dangerous asteroid Apophis when it makes its next close fly-by of Earth in 2029.

This contract is in addition to the $75 million development contract awarded OHB Italia in 2024. According to the company’s press release here:

The launch is scheduled for April 2028, with a rendezvous with Apophis planned for February 2029, approximately two months before its close approach to Earth. The spacecraft will accompany the asteroid until August 2029, in order to observe in detail how Earth’s tidal forces modify its shape, rotation, orbit and surface characteristics.

The initiative also benefits from strong international cooperation. The Japan Aerospace Exploration Agency (JAXA), drawing on its well-established expertise in asteroid science, will contribute by providing launch service onboard an H3 rocket, the spacecraft’s solar arrays and a Thermal Infrared Imager, further reinforcing the project’s global dimension.

In addition, two cubesats will be launched with Ramses and deployed once the spacecraft reaches Apophis.

This schedule is very tight, which places great pressure on OHB, especially because European space projects are traditionally built slowly after years of planning. ESA almost never does things fast like this.

At the moment, Osiris-Apex (formerly Osiris-Rex) is the only spacecraft that is on its way to Apophis.

Rocket startup Stoke Space raises an additional $350 million in private investment capital

9:22 am

Stoke's Nova rocket
Stoke’s Nova rocket, designed to be
completely reusable.

The rocket startup Stoke Space yesterday announced that its most recent fund-raising round has raised an additional $350 million in private investment capital above the original target of $510 million.

Stoke Space Technologies, the rocket company developing fully and rapidly reusable medium-lift launch vehicles, announced today an extension of its previous Series D financing, bringing the total amount raised in the round to $860 million. The round was initially announced in October 2025 at $510 million. That funding focused on completing activation of Launch Complex 14 at Cape Canaveral Space Force Station, Fla., and expanding production capacity for the Nova launch vehicle. Stoke will use the additional capital to accelerate future elements of its product roadmap.

In total the company has now raises $1.34 billion. Though it has been moving steadily towards the first test launch of its totally reusable Nova rocket, it has so far refused to announce any launch dates. Based on all accounts, it appears that launch could occur before the end of this year, but nothing is confirmed.

Stoke’s ability to raise so much capital contrasts sharply with the failure of the British rocket startup Orbex, as noted in my previous post. Investors know that when Stoke is ready to launch from Florida, it will be able to do so, and so they have confidence in the company. With Orbex no one was willing to invest because the investors recognized that red tape was handicapping the company.

British rocket startup Orbex goes under

9:10 am

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

After waiting four years to get the necessary launch licenses from the United Kingdom’s Civil Aviation Authority (CAA), delays that forced it to abandon its preferred spaceport in Sutherland to go to the SaxaVord spaceport in the Shetland Islands, the British rocket startup Orbex today announced its effort to find a buyer or new financing had failed and it is going into receivership with the goal of selling off its assets.

Orbex has filed a notice of intention to appointment Administrators and will continue trading while all options for the future of the company are explored, including potential sale of all or parts of its business or assets. The notice provides short-term protection and allows the business time to secure as positive an outcome as possible for its creditors, employees and wider stakeholders.

The funding required for Orbex to remain a viable business was sought from a variety of public and private investors during its Series D funding round, which has ultimately failed. Several merger and acquisition opportunities have also been explored, with none resulting in a favourable outcome.

To repeat this company’s sad story, 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.

By 2024 Orbex realized launching from Sutherland was impossible, and it then switched to the Saxavord spaceport in the Shetland Islands. This forced more delays because the company had no facilities there. It had already spent a fortune building everything for Sutherland.

There will be many who will blame this failure on the difficulty of rocket science, but it appears the fault almost entirely lies with the UK government and its odious regulatory regime. Neither Sutherland nor SaxaVord have been able to get anything off the ground, and it appears right now that rocket companies are going everywhere else to find launch sites. New rockets must launch and fail so that they can eventually succeed. The sense I get from the CAA is that it is treating every launch not as a test but as an operational launch that must succeed. Orbex couldn’t meet that standard.

Nor can any other rocket startup. At the moment SaxoVord has only one customer planning to launch, the German startup Rocket Factory Augsburg, but after a static fire explosion in 2024 blocked the launch nothing has happened since. I suspect the company is having problems getting new launch approvals from the CAA.

China completes launch abort test of Mengzhou capsule; also vertically lands Long March 10A 1st stage in ocean

7:50 am

Long March 10A 1st stage splashing down softly on test flight
Click for source.

China today completed a major test for its future manned lunar program. In launch for the first time the first stage of its new Long March 10A, it not only succeeded in completing a launch abort of its next generation Mengzhou manned capsule — intended not only for its space station but for its manned lunar program — the first stage successfully completed a vertical soft splashdown in the ocean.

The uncrewed vessel took off from the Wenchang Satellite Launch Centre on the southern island of Hainan aboard a Long March-10 prototype test rocket at 11am on Wednesday.

The Mengzhou vessel separated from the rocket shortly after launch, before splashing down in the ocean at its designated landing spot, according to the China Aerospace Science and Technology Corporation (CASC).

The first stage of the Long March-10 rocket also safely splashed down in its designated ocean landing spot, CASC said. The state-owned aerospace contractor developed both the rocket and the crewed spacecraft.

Courtesy of BtB’s stringer Jay, video of the launch can be seen here. Jay also found two additional images, one showing the stage just before splashdown standing vertical (as shown in the picture to the right) and the other of the stage floating in the water just before it was picked up by a recovery vessel. According to comments at these tweets, it is speculated that the interstage unit that connected the capsule to the stage was either ejected at landing or was torn off when the stage hit the water.

This is a major achievement for China. It gets it closer to being able to use Mengzhou for longer missions to places like the Moon.

The modular Mengzhou spacecraft has two variants: a seven-astronaut near-Earth model designed to support the country’s Tiangong space station and a model with a smaller crew capacity for missions to the moon. The latter is expected to work in tandem with the Lanyue lunar surface lander, designed to carry two astronauts to the moon’s surface.

The soft splashdown of the Long March 10A first stage also gets China closer to its first reuse of a rocket.

I must note that this success is part of a larger story about China’s space industry that is not so hopeful.

Hubble eyes the Egg Nebula

Hubble eyes the Egg Nebula
Click for original image.

Cool image time! The picture to the right, reduced to post here, was taken by the Hubble Space Telescope as part of a study of “preplanetary nebula,” the initial stages of a planetary nebula that forms as some star types begin dying. From the caption:

Many preplanetary nebulae are relatively dim and hard to spot. They are made of layers of gas ejected by the star, but that star is not yet hot enough to ionise the gas and cause it to glow. The Egg Nebula is relatively unique, easily visible as a sparkling jewelled egg in space. Powerful beams of starlight blast out of the inner cloud, two a-side, giving a breathtaking illumination to this cosmic structure. Fast-moving outflows of hot molecular hydrogen also emerge from within the dust cloud, visible just at the base of the searchlight beams. These outflows glow with infrared light, which is shown in this image by orange highlights.

The central cloud of dust is surrounded by concentric rings, themselves made up from thin, faint arcs of gas. These were created by successive outbursts from the central star, which ejected a little more material from its outer surface every few hundred years. The beams of starlight are reflected by these layers of gas, creating an appearance like ripples on the surface of water. The way that gas molecules reflect and scatter light gives a bluish colour to the arcs. The reflected starlight reveals important details about the central star, which is impossible to view directly in its dusty shell.

Many planetary nebula get their spectacular shapes because they have a binary star system in their center, that act like the blades in a blender as they circle each other, mixing the materials the stars’ eject to form those shapes. Because of those surrounding shells, it is often impossible to determine with the nebula has a single central star, or a binary system.

First Vulcan rocket arrives at Vandenberg for launch later this year

8:53 am

ULA has now delivered parts of a Vulcan rocket to Vandenberg Space Force Base in California as it prepares for that rocket’s first launch from that spaceport later this year.

ULA’s RocketShip recently docked at the harbor on the South Base with the Vulcan rocket components stowed inside the huge cargo vessel. … Crews spent several days offloading the hardware while mindful of tides that could have delayed the delivery.

…On the first day, workers removed the Vulcan’s Centaur upper stage from the RocketShip, followed by the booster the next day. “We tried to take off the payload adapter and the interstage adapter and, unfortunately, the swells were pretty bad,” Fortson said. After pausing the unloading chores for two days, the swells cooperated so the team didn’t have to wait for the next opportunity for suitable tides a couple of weeks away.

ULA hopes to get the launch off by June 2026, but that schedule will depend on whether the launchpad conversion from the Atlas-5 rocket can be completed. It also depends on whether the payload is ready on time. It appears this launch will be one of ULA’s seven national security launches for the Pentagon, though this is not confirmed.

Starfish gets a second satellite servicing contract from Pentagon

8:42 am

The orbital tug startup Starfish has now won a second major satellite servicing contract from the military to use its Otter tug to either service or de-orbit defunct military satellites.

The first contract, announced in late January, was from the Space Force’s Space Development Agency (SDA) for $52.5 million. Under that deal, Starfish would fly an Otter in 2027 to dock with a satellite and then de-orbit it.

The new contract, announced February 7, 2026, is with the Pentagon’s APFIT program, designed to encourage “innovative technologies”. It is for an additional $54.5 million, and calls for Otter to dock with a satellite in 2028 and service it rather than de-orbit it.

The Otter is designed to autonomously dock with and maneuver national security satellites, maximizing their operational capabilities while supporting SSC’s [Space Systems Command] need for sustained space maneuver. The spacecraft leverages autonomous rendezvous, proximity operations, and docking technology, allowing it to service satellites that were not originally designed for servicing.

As I noted in January when the first de-orbit contract was announced, while a number of contracts have been issued in the U.S., Europe, and Japan to demonstrate de-orbit technology, that was the first operational de-orbit contract. As for servicing, Northrop Grumman has already succeeded several times in prolonging the life of defunct commercial geosynchronous satellites with its Mission Extension Vehicle (MEV).

Starfish’s Otter however has only successfully demonstrated rendezvous and proximity capabilities on two missions, with a third a failure. As for docking, its Otter Pup tug has flown two missions, with the first failing in 2023 when both spacecraft began spinning unexpected. The second mission is presently ongoing, and was supposed to achieve a docking by now. After completing rendezvous maneuvers in September Starfish has provided no new updates. As far as we know, the docking never occurred or was a failure.

These contracts however suggest it has succeeded. Why else would the military suddenly issue more than $100 million in contracts to the company?

Has Roscosmos gotten its Baikonur Soyuz-2 launchpad fixed already?

8:18 am

According to a short sentence added today at the end of Anatoli Zak’s ongoing report on the damaged Soyuz-2 launchpad in Baikonur, Russia’s space agency Roscosmos has completed repairs on that pad early.

According to rumors from Baikonur, the new service platform was installed at Site 31 by Feb. 10, 2026.

That’s it. No other information. Furthermore, this follows the last report from a Roscosmos official in late January where he said repairing the pad by March was facing difficulties due to winter weather and delays in getting replacement parts.

The launchpad had become unusable following the last launch in November when a platform used to prepare the rocket fell into the pad’s flame trench. It had not been attached properly.

As this report is based on rumors and very limited information, it must be treated with caution.

Voyager wins four-year $24.5 million ISS management contract from NASA

8:01 am

The space station startup Voyager Technologies yesterday won a four-year $24.5 million contract from NASA to apparently manage the agency’s missions to ISS.

Under the task-order contract, Voyager will deliver end-to-end mission services spanning payload integration, mission operations, safety and compliance, and post-mission closeout. NASA may add options that extend the scope and value of the agreement over its life, providing Voyager with a multi-year framework for recurring mission execution. Voyager anticipates onboarding three payload missions over the next quarter, reflecting near-term demand and a steady pipeline of task orders supporting ongoing ISS operations.

The company has been doing similar ISS work for NASA at the Johnson Space Center in Texas, though this contract appears to expand that work considerably. This deal provides the company further experience operating space station missions, crucial for the Starlab station that Voyager is listed as the consortium’s lead company.

Of the five stations under development, Axiom has run tourist missions to ISS to demonstrate this capability, Vast is launching its own demo single module station to demonstrate this capability, and now Voyager is doing this work for NASA to demonstrate this capability.

Max Space, which only entered this race late last year, has no such contract or experience, but it has recently partnered with Voyager in other work, and plans to launch its own demo station module in ’27.

The last proposed space station, Orbital Reef, has no such deal as far as I know. Led by Blue Origin (partnered with Sierra Space), this station project continues to show no progress of any kind.

How Saturn’s moon Enceladus causes an aurora on Saturn

9:38 am

Enceladus orbiting Saturn
Click for original image.

Using data collected by the orbiter Cassini while it orbited Saturn more than a decade ago, scientists now think they have mapped out how the moon Enceladus interacts with Saturn’s magnetic field and helps create an aurora in Saturn’s polar regions.

You can read the paper here. The artist rendering to the right comes from the press release, and shows that interaction. From that release:

The study, published in the Journal of Geophysical Research: Space Physics, shows how wave structures, known as ‘Alfvén wings’, travel like vibrations on a string along magnetic field lines connecting Enceladus to Saturn’s pole. The initial ‘main’ Alfvén wing is reflected back-and-forth both by Saturn’s ionosphere and the plasma torus that encircles Enceladus’s orbit, resulting complex and structured system. By using a multi-instrumental approach, researchers were able to show that the influence of Enceladus extends over a record distance of over 504,000 km – more than 2,000 times the moon’s radius.

…As well as the large-scale structures, the team found evidence that turbulence teases out the waves into filaments within the main Alfvén wing. This fine-scale structure helps the waves bounce off Enceladus’s plasma torus and reach the high-latitudes in Saturn’s ionosphere where auroral features associated with the moon form.

The white haze below Enceladus in the graphic represents the material that comes out of the “tiger stripe” fractures near its south pole.

A lava tube on Venus?

9:18 am

Theorized lava tube on Venus

The uncertainty of science: Scientists in Italy have reanalyzed the radar data of Venus by the Magellan orbiter from 1990 to 1992 and concluded that at least one open pit on the side of a shield volcano might be the entrance to a underground lava tube.

You can read their paper here [pdf]. The graphic above comes from figures 2 and 3 of their paper, with the radar image of the pit to the right, and the cartoon to the left their interpretation of that radar data. From the abstract:

Between 1990 and 1992, the Synthetic Aperture Radar (SAR) instrument on board the Magellan spacecraft mapped the Venusian surface. By leveraging a SAR imaging technique developed for detecting and characterizing accessible subsurface conduits in the proximity of skylights, we analysed
the Magellan radar images in locations where there is evidence of localized surface collapses. Our analyses reveal the existence of a large and open subsurface conduit in the Nyx Mons region. This feature is hypothesized to be a pyroduct, characterized by a diameter of about 1 km, a roof thickness of at least 150 m and an empty void height of no less than 375 m. The conduit extends in the subsurface for at least 300 meters from the skylight.

To strengthen their conclusions, which are based on a LOT of assumptions, the scientists also compared this radar data with radar data taken of similar-sized lava tube skylights on Earth.

Their conclusion is reasonable, as Venus is a planet of volcanoes, with more than a million detected in radar data. Lava tubes should exist. Nonetheless, their interpretation of the radar data is very uncertain, and must be viewed with a great deal of skepticism.

FAKE Chandrayaan-2 images of the Apollo 11 and 12 landing sites

Chandrayaan-2 images of Apollo 11 and Apollo 12 landing sites

The pictures to the right are fake, as are the two stories I had linked to in the now crossed-out post below. Both stories included pictures of the Apollo 11 and Apollo 12 landing sites that were fake and did not match the actual pictures taken earlier by Lunar Reconnaissance Orbiter.

I seem to remember that Chandrayaan-2 had taken pictures of these Apollo landing sites, but I have not been able to find those originals. Either way, the stories below as well as the pictures to the right are fake, and for that reason I have deleted the links to both.

For reasons I don’t understand, two different news outlets in the past two days decided to highlight the 2021 images taken by India’s Chandrayaan-2 lunar orbiter of the Apollo 11 and 12 landing sites, with both outlets claiming these pictures provided third-party verification that those manned lunar landings actually happened.

Those pictures are to the right. They aren’t new, but they are so good I decided they were cool enough to post again.

As for proving the lunar landing happened, that is pure anti-American silliness, sadly too often pushed by ignorant Americans. They should be ashamed. The Apollo landings were possibly the greatest single achievement Americans have ever accomplished. And if not the greatest, the landings rank near the top, and above all they certainly were among our noblest achievement.
