Russia launches the smallest version of its Angara rocket

9:34 am

Russia today successfully launched the smallest version of its Angara rocket, dubbed Angara-1.2, from its Plesetsk spaceport in northeast Russia, placing a number of classified payloads into orbit.

Russia’s state-run press released almost no information about this launch, partly because of its military nature but also because it has discovered recently that the Plesetsk spaceport is within range of Ukrainian drones, with one attack causing a launch to be scrubbed.

China picks two Pakistanis to train for a future Tiangong-3 mission

9:22 am

As part of its Soviet-style propaganda effort to promote its space program, China yesterday announced the names of the two Pakistanis who will train for a future short mission to its Tiangong-3 space station.

The agency said in a statement that Muhammad Zeeshan Ali and Khurram Daud will come to China soon as reserve astronauts for training. After completing all training and evaluations, one of them will participate in a space mission as a payload specialist, becoming the first foreign astronaut onboard the Tiangong space station.

This flight is part of Pakistan’s partnership with China in its International Lunar Research Station (ILRS) project to build a lunar base, created by China to counter the U.S.’s Artemis Accords alliance. Pakistan will also fly a small demo rover on China’s Chang’e-8 unmanned lunar mission, scheduled presently for a 2029 launch.

While the American alliance has now signed 63 nations covering most of the world’s major nations, only thirteen nations and about eleven eleven academic or governmental bureaucracies — mostly third world — have joined China.

This Chinese international manned mission mirrors largely what the Soviets would do during the Cold War, flying someone from one of its captured countries to garner international propaganda points. Do not expect these astronauts to do much concrete work. During the Soviet era, the Russians would joke that these foreign astronauts would all get “red hands” disease, caused whenever they tried to touch anything and a Russian astronaut would then slap their hands, saying firmly “Don’t touch that!”

Rocket Lab launches satellites for Japan’s space agency JAXA

9:56 pm

Rocket Lab today successfully placed eight smallsats for Japan’s space agency JAXA, its Electron rocket lifting off from one of its two launchpads in New Zealand.

Because all of JAXA’s rockets are presently grounded due to technical failures, Japan’s space agency has had to turn to Rocket Lab. In fact, these eight satellites were originally supposed to launch on JAXA’s Epsilon-S rocket, which remains grounded after an explosion during a static fire test. There have been no updates on the status of Epsilon-S since December 2024.

Rocket Lab was also supposed to do a suborbital hypersonic test flight yesterday out of Wallops Island in Virginia, using the first stage of Election in its HASTE suborbital configuration. As this is a test for the War Department, little information is generally released. This video from a distance confirms the launch apparently took place, but whether it was a success or not remains unknown. That Rocket Lab’s announcers did not tout its success either before or after today’s JAXA launch — as they have routinely done in the past — suggests something might have gone wrong, though this too is pure speculation.

Curiosity looks at a small crater as it climbs Mount Sharp

11:50 am

Antofagasta crater
Click for full resolution. Click here, here, and here for original images.

Cool image time! The panorama above, created from three pictures taken by the right navigation camera on the Mars rover Curiosity (see here, here, and here), takes a look at a small relatively fresh crater on the slopes of Mount Sharp. From an update from the rover’s science team yesterday:

At the beginning of the week, Curiosity arrived right on target on the rim of the 10-meter (33 feet) “Antofagasta” crater. The crater looked fresh and deep as we had hoped with a nice well-defined rim that didn’t look too eroded, but the bottom of it turned out to be filled with dark rippled sandy material that covered up the most interesting rock layers. There were a few rock exposures just above the sand cover that seemed like they might have been deep enough to have been sheltered from space radiation between the time their sediments were deposited and the crater-forming impact, but reaching them from the rim would have put the rover at such an awkward angle that we wouldn’t have been able to deliver the sample to the instruments.

Overview map
Click for interactive map.

It’s possible that we might have been able to get into a better position by instead placing the rover on the rippled crater fill, but the chance that the rover could get stuck in all that sand made it much too high a risk. We also looked at the nearby blocks in case they could have been ejecta from the crater, but since all the rocks visible in the crater wall looked very similar to each other, there wasn’t a good way to tell which ejecta blocks might have come from the deeper layers of the crater. Because of this, the team decided against attempting to drill in or around the crater.

The overview map to the right provides the context. The blue dot marks Curiosity’s location when the pictures above were taken. The yellow lines roughly indicate the area covered by the panorama. The red dotted line marks the future planned route, the white dotted line the rover’s actual travels.

Note the flat rocks in the foreground of the panorama, all part of the crater’s rim. Each looks like a large flat paving stone that was very precisely shattered into numerous tiny pieces, all about the same size. Very strange. On Earth you’d assume some craftsman had laid these small pieces down like tiles, but of course, that couldn’t have happened on Mars.

The European startup Atmos announced today that it has raised an additional €25.7 million [$30 million] as part of its ongoing commercial program to develop its Phoenix orbital research capsules that will fly in space for several months — where products can be produced in weightlessness — and then return those products safely to Earth.

The funding will support an initial three-vehicle PHOENIX 2 fleet, the launch of ATMOS WORKS for governmental and defence customers, and development of PHOENIX 3, the company’s next-generation orbital return vehicle.

The round is co-led by Balnord and Expansion, and joined by Keen Defence and Security. The European Innovation Council (EIC) participates through its Accelerator programme via blended financing, combining grant and equity components. Additional investors include OTB Ventures, High-Tech Gründerfonds (HTGF), APEX Ventures, Seraphim, Faber, E2MC, Kirch Ventures, Lennertz & Co., Mätch VC, MBG Baden-Württemberg, and Tech Horizons.

Since the American company Varda successfully demonstrated there was money to be made flying these small recoverable capsules, investment capital has poured into this industry. In the U.S. Varda, Inversion Space, and Sierra Space, have raised money for doing such orbital work. In Europe, The Exploration Company in France, Atmos in Germany, PLD in Spain, Genesis in Croatia, and Space Cargo in Luxembourg have also raised capital.

At this moment, however, only Varda has successfully launched and recovered a capsule.

Northrop Grumman lost $71 million from its bottom line because of its solid-fueled booster failures

9:00 am

In its most recent financial statement, Northrop Grumman admitted it took a $71 million charge due to nozzle failures on two of its solid-fueled boosters, dubbed GEM 63XL, during two different launches of ULA’s Vulcan rocket.

In a statement about its first-quarter financial results, the company said its Space Systems division recorded a $71 million “unfavorable adjustment” to earnings at completion on its GEM 63XL booster “associated with a launch anomaly that occurred during the first quarter.”

The GEM 63XL solid-fuel booster is used on United Launch Alliance’s Vulcan Centaur rocket. On a Feb. 12 launch, one of four boosters shed debris about 65 seconds after liftoff. The “observation,” as ULA termed it initially, did not affect the success of the USSF-87 mission, placing its payload into its planned geosynchronous orbit.

ULA later called the incident a “significant performance anomaly” with the booster that it would investigate before returning Vulcan to flight. The vehicle has not launched since then.

A similar incidence took place during an earlier Vulcan launch, with the rocket’s core stage and the remaining undamaged boosters getting the payload into the proper orbit. The continuing problem however has now grounded Vulcan, though the military is considering using it for some small payload launches, without the GEM strap-on boosters.

As a result, the Pentagon has already shifted several launches from ULA to SpaceX, costing ULA a significant amount of revenue. In addition, Vulcan’s grounding will impact the launch of Amazon’s Leo internet constellation, which had a major contract with ULA to get its Leo satellites into orbit.

Jordan to sign the Artemis Accords

7:42 pm

According to a press announcement tonight from NASA, Jordan will sign the Artemis Accords on April 23, 2026 at NASA headquarters in Washington, DC.

NASA Administrator Jared Isaacman will host Ambassador Dina Kawar of the Hashemite Kingdom of Jordan and U.S. Department of State Principal Deputy Assistant Secretary for Oceans and International Environmental and Scientific Affairs Ruth Perry for the ceremony.

Jordan becomes the 63rd nation to sign the accords. It also joins Bahrain, Oman, Saudi Arabia, and the United Arab Emirates from the Arab Middle East. While it is certainly wise to not trust any nation controlled by Islam, having these nations allied with us in space will help mitigate the worst aspects of their religion. That they are also joining a space alliance that includes Israel is another indication that they are realizing that their future is better aligned with Israel than against it.

The full list of nations in this American space alliance is as follows:

Angola, Argentina, Armenia, Australia, Austria, Bahrain, Bangladesh, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Israel, Italy, Japan, Jordan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malaysia, Mexico, the Netherlands, New Zealand, Nigeria, Norway, Oman, Panama, Peru, Poland, Portugal, Romania, Rwanda, Saudi Arabia, Senegal, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the Philippines, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

Japan to do test launch of its H3 rocket in June

1:28 pm

Japan’s space agency JAXA is now planning a test launch on June 10, 2026 of its H3 rocket, carrying a dummy payload only in order to test the changes it has made in the rocket after a failed launch in December 2025.

The failure of the eighth H3 rocket was likely caused by an adhesion problem in the satellite mounting structure, which led it to break apart during flight, according to an investigation by JAXA. Similar issues were found in other units, prompting the space agency to fix them so the components can maintain their structural integrity.

In the June launch, a dummy satellite will be mounted on the test vehicle to collect data and verify the effectiveness of the measures. For future launches of actual satellites or space probes, JAXA plans to review the mounting structure design to reduce the risk of failure.

In other words, the method for attaching the payload to the rocket at some points failed, so that the satellite separated prematurely. The June launch will be to test a new mounting system.

Posting has been light the last few days as I deal with recovery from knee surgery.

Two launches by SpaceX

12:02 am

In the past two days SpaceX completed two more launches. The first, yesterday morning, placed 25 more Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California. The first stage completed its 8th flight, landing on a drone ship in the Pacific.

Then tonight SpaceX launched a GPS satellite for the Space Force, its Falcon 9 rocket lifting off from Cape Canaveral Space Force Station in Florida. The first stage completed its 7th flight, landing on a drone ship in the Atlantic. That drone ship, “Just read the instructions,” is now being shifted to support Starship operations, and will no longer be used for Falcon 9, after supporting 155 first stage landings. What it will do in connection with Starship has not been made clear. The two fairing halves completed their 2nd and 3rd flights respectively.

The Space Force had originally intended to launch this satellite on a ULA Vulcan rocket, but a month ago it shifted the contract to SpaceX because of the nozzle problem that has plagued two different ULA Vulcan launches. Because of this shift, the time from contract award to launch was the quickest by SpaceX for the Space Force.

The leaders in the 2026 launch race:

48 SpaceX

For the third straight year SpaceX continues to lead the entire world combined in total launches, 48 to 37.

NASA’s IG: With only Axiom building NASA’s future spacesuits, the agency’s lunar program faces great scheduling risk

12:23 pm

Axiom's two spacesuits being tested underwater
Axiom’s two spacesuits being tested underwater in October 2025.
Click for original.

According to NASA’s inspector general’s report today [pdf] on the state of NASA’s effort to create new spacesuits for use by its astronauts on future space stations as well as in its Artemis lunar program, the planned schedules for the lunar landing and those stations are threatened because the agency presently has only one contractor, Axiom, building new suits, and has not established any spacesuit standardization rules should it want to issue contracts to others. From the report’s conclusion:

While NASA is taking steps to mitigate schedule risk, it must also contend with the unique risks inherent to a single-provider environment until future competition is introduced. … If Axiom cannot satisfy its contractual requirements in a timely or cost-effective manner, then NASA could be forced to continue using the problematic EMUs throughout the life of the ISS and significantly adjust its lunar plans. [EMUs are the complex suits presently used on ISS, and would not work well for any lunar landing mission.]

While xEVAS [the new suit concept] is flexible enough to allow for additional providers, doing so may not help the Agency meet its more immediate Artemis goals. Critically, NASA must address existing design and safety risks resulting from the lack of standard requirements for spacesuits to be compatible with various lunar spacecraft and assets.

As shown by the photo above, the development of Axiom’s spacesuit has been proceeding, and seems likely to be available for next year’s Artemis-3 Earth orbit test mission. At the same time, it is still behind schedule, a fact that has been mitigated because NASA’s entire Artemis program is equally behind schedule.

The report lists three commercial companies that might be able to provide alternative suits, and thus some redundancy, as shown by the image below.

Hubble looks at the Trifid Nebula again

9:59 am

Trifid Nebula as seen by Hubble
Click for original image.

Cool image time! The picture to the right, cropped to post here, was taken by the Hubble Space Telescope and released today. It shows a small section of the Trifid Nebula, located about 5,000 light years away.

This location has been imaged numerous times in the past by Hubble. The area shown illustrates some fundamental aspects of stellar and nebula formation. The dark area in the lower right is a thick dust cloud. Several energetic O and B supermassive stars are out of view at the top. The radiation from these stars (indicated by the blue), is hitting that dust cloud and literally destroying it. It appears that the foreground “horn” exists because a larger object is blocking the radiation, allowing dust to survive in the background.

I have no explanation for the background “horn”.

This new image was taken in parallel with an image of the entire Trifid Nebula, taken by the new Rubin Telescope in Chile. Though Rubin cannot see with the same resolution as Hubble, its image is quite worthwhile viewing.

New Glenn launches for 3rd time, reuses first stage and lands it, but fails to put satellite in correct orbit

11:54 am

New Glenn's first stage, just prior to landing
New Glenn’s first stage, just prior to landing

Blue Origin in the early morning hours today successfully completed the third launch of its New Glenn rocket, lifting off from Cape Canaveral Space Force station in Florida and placing in orbit AST SpaceMobile’s Bluebird-7 cellphone satellite. For Blue Origin, this launch was the first for a commercial outside customer, a significant step forward for the company, which has sadly earned a reputation for operating too slowly.

Unfortunately, according to an update from Blue Origin the satellite was deployed but in an “off nominal orbit.” An update just posted by AST states the satellite is a loss and is being de-orbited. This satellite would have been the seventh in AST SpaceMobile’s 45-60 satellite constellation designed to act as cell towers in space. AST hopes to have at least half the constellation in orbit by the end of ’26. Several major phone companies, such as AT&T, Verizon, and Vodaphone in Europe, have already signed on.

For Blue Origin, the launch wasn’t a total failure. The rocket’s first stage had flown in November 2025 on the second New Glenn flight, and was refitted (with a new set of engines) to fly again on this flight, the rocket’s third. It not only did its job, getting the upper stage into space, it successfully landed for the second time on New Glenn’s barge in the Atlantic. This fast reuse and successful landing should do a great deal to improve the company’s slow reputation. Unfortunately, the failure to deliver the customer’s satellite will counter that most significantly.

As for Blue Origin, this was its first launch in 2026, and it was also unsuccessful. The leader board for the 2026 launch race remains unchanged:

EU releases revised Space Act proposal, and it is as odious as the earlier drafts

11:24 am

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

The Council of the European Union (EU) in Brussels at the end of March released [pdf] a revised draft of its proposed Space Act that would impose a single regulatory framework for all space activities across the entire EU.

I have just finished reading this odious 157-page monstrosity, and I can say without question if passed it will not only isolate Europe from all international space commercial activity, it will squelch any possibility that Europe will develop its own space industry.

The first draft of the law, first put forth in 2025, was routinely blasted by American officials, by think tanks in and out of Europe, and by industry representatives. It imposed byzantine regulations on Europe’s space industry while also demanding that non-European companies be required to follow these rules as well, national sovereignty be damned.

The newly released draft does the same, but now does so in a manner that is somewhat vague and unclear.

That lack of clarity includes what is required to comply with the regulations. “There are a lot of things where it says you need to do X. What counts as X? Who knows,” said Gabriel Swiney, director of the Office of Space Commerce’s policy, advocacy and international division. “It will probably be determined at some point by some European committee or standards body.”

“Without regulatory clarity with what the regulatory picture should be, it’s really going to have a stifling effect on what industry is striving to do,” said Janna Lewis, senior vice president of policy and general counsel for Astroscale U.S.

The first draft was delayed and apparently rejected because the member nations of the EU opposed it. It appears this new version, having done nothing to ease their concerns, might already be on its way to the dead letter office.

We shall see. If there is anything dear to the hearts of the EU bureaucrats in Brussels, it is imposing insane regulations on others. It appears those bureaucrats haven’t given up — despite opposition by numerous European governments — and are working hard to win that right in space.

Final ground testing begins of Katalyst’s Swift rescue spacecraft

5:46 am

Katalyst's proposed Swift rescue mission

Click for original image.

Only seven months after NASA awarded the satellite repair startup Katalyst the contract to save the Gehrels-Swift space telescope, the company has delivered the completed LINK spacecraft to the Goddard Space Flight Center in Maryland for final ground testing.

Katalyst will move forward with LINK’s vibration and thermal tests using NASA Goddard’s in-house facilities in the coming weeks before installation into Northrop Grumman’s Pegasus rocket at the agency’s Wallops Flight Facility in Virginia.

Gehrels-Swift has been one of NASA’s most productive space telescopes. Unfortunately its orbit is decaying and if nothing is done to raise that orbit it will burn up in the atmosphere in 2029 or so. To extend this timeline engineers have stopped almost all science work in February.

Katalyst hopes to launch LINK as soon as later this year. It was able to get it built so quickly because it was already under construction as the company’s first demo of its repair technology. When NASA put out a bid for boosting Swift, the company shifted gears and reconfigured LINK for this mission.

If successfully, the achievement will be a major coup for this startup.

Engineers shut down another instrument on Voyager-1

5:31 am

The Voyager missions
The routes the Voyager spacecraft have
taken since launch. Not to scale.

Due to the continuing and expected decline in power, engineers have now shut down another instrument on Voyager-1 in the hope of keeping the spacecraft operating for just a few more years.

On April 17, engineers at NASA’s Jet Propulsion Laboratory (JPL) in Southern California sent commands to shut down an instrument aboard Voyager 1 called the Low-energy Charged Particles experiment, or LECP. The nuclear-powered spacecraft is running low on power, and turning off the LECP is considered the best way to keep humanity’s first interstellar explorer going.

The LECP has been operating almost without interruption since Voyager 1 launched in 1977 — almost 49 years. It measures low-energy charged particles, including ions, electrons, and cosmic rays originating from our solar system and galaxy.

…The choice of which instrument to turn off next wasn’t made in the heat of the moment. Years ago, the Voyager science and engineering teams sat down together and agreed on the order in which they would shut off parts of the spacecraft while ensuring the mission can continue to conduct its unique science. Of the 10 identical sets of instruments that each spacecraft carries, seven have been shut off so far. For Voyager 1, the LECP was next on that list. The team shut off the LECP on Voyager 2 in March 2025.

Both spacecraft now have only three operating science instruments. Engineers hope a major reboot on both spacecraft planned later this year might make each operate more efficiently, allowing both to survive maybe until 2030. At a minimum the hope is to make them last until 2027, which would the fiftieth anniversary of their launch.

The bottom line remains: the nuclear power source on board both is running down. The goal now is less gathering science data and more engineering: How long can we keep these spacecraft alive, at the very outskirts of our solar system?

The space agencies of Canada and Europe agree to exchange classified information

1:51 pm

Canada:
Canada: “We let our government do it all!”

In what appears to be the increasing policy of the Canadian Liberal government to align its space program with Europe, the Canadian Space Agency this week signed an agreement with the European Space Agency that will make it possible for them to freely exchange classified information.

The European Space Agency (ESA) and Canada have signed a General Security of Information Agreement (GSOIA), which will establish a legally binding framework for the exchange of classified information. The agreement was signed on 14 April at the 41st Space Symposium in Colorado Springs, USA, by ESA Director General Josef Aschbacher and President of the Canadian Space Agency Lisa Campbell, on behalf of the Government of Canada.

The GSOIA will ensure that both parties uphold the highest standards of security while enabling the secure exchange of sensitive information entrusted to authorised institutions and industrial partners. It provides a robust foundation for cooperation in areas where the protection of classified information is essential. In particular, the agreement will facilitate closer collaboration in strategic domains such as space-based surveillance, disaster response and security-related technologies. It will also support the development of dual-use capabilities, including advanced sensing systems, secure communications and emerging space technologies.

Canada is the only country not in Europe that is a partner in ESA. This deal, plus Canada’s recent commitment to provide a half billion dollars of funding to ESA projects, illustrates the Liberal government’s policy to look to Europe more for its space effort, rather than the United States.

This appears also to be part of the Liberal government’s shift away from capitalism and towards a government-based space effort, a decision that is certain to produce few results while wasting a lot of money.

The space station startups: NASA’s new space station plan is mistaken

9:01 am

The American space stations under development

At a conference event this week officials from three of the five American space station startups expressed strong disagreement with NASA’s new space station plan.

The new plan would have NASA build and launch its own new core module, dock it with ISS, and have the new stations attach their first modules to it prior to flying freely. NASA proposed this plan because it does not believe there is enough market to sustain the stations independently and NASA doesn’t have the budget to fully fund them.

The officials repeatedly disagreed about the market issue.

“We believe not only we can be ready by 2030” when the International Space Station is slated to be retired, “but we also believe that we can be profitable on the current market, not waiting for the future market we all will develop and will be successful at,” said Max Haot, CEO of Vast [building the Haven-1 and Haven-2 stations].

…Haot and executives from Axiom Space and Starlab Space said their responses to NASA’s request for information — which were due April 8 — show otherwise. “We put in 390 pages of independent analysis, research studies, datas, contracts, those types of things,” said Marshall Smith, CEO of Starlab Space, which is targeting 2029 for its station to be on orbit. “We’re being very clear and what we can do and how that works.”

One prominent revenue stream the panelists pointed to is other space agencies and nations eager to send their astronauts and payloads to space. “We’ve flown 12 people to space that paid us money to do that,” said Jonathan Cirtain, CEO of Axiom Space, referring to the four private astronaut missions it’s conducted to ISS. “We’ve flown 166 payloads today. All of those are paying payloads that generate revenue for the company.” The Texas company plans to begin operating in 2028 when its first two station modules are slated to be in orbit, then gradually grow the station to five modules.

The officials also said the core module idea would actually slow things down. NASA would have to first build and launch it, and would be starting from scratch to do so. It takes years to build such a thing, and it will certainly not be ready by 2030, when ISS is presently supposed to be retired. Moreover, forcing them to dock to this module would force them all to completely change their own plans, something they all find counter-productive.

In announcing NASA’s core module plan, NASA administrator Jared Isaacman also stated that he was open to industry feedback. I suspect that his core module proposal is going to die, and be replaced with the more direct transition from ISS to these private stations, the approach these companies favor.

I should add that the three startups that spoke up at this conference are also the three that are in the lead to build their stations, according to my rankings below. As far as I can tell, they are all tied for first place, with their station development very robust and well financed.

Two launches since yesterday, by Russia and China

8:26 am

The launch beat goes on! Russia and China each completed launches since yesterday, with Russia first placing a classified military payload involving “multiple spacecraft”, its Soyuz-2 rocket lifting off from its Plesetsk spaceport in northeast Russia. The rocket’s flight path took it over the Arctic, so the core stage and four strap-on boosters fell harmlessly in the ocean.

Next, China placed what it claimed was a “high-precision greenhouse gas detection” satellite into orbit, its Long March 4C rocket lifting off from its Jiuquan spaceport in northwest China. China’s state-run press provided no other information. Nor did it indicate where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China.

The leaders in the 2026 launch race:

Latvia to sign Artemis Accords

3:27 pm

NASA announced today that Latvia will be signing on to the Artemis Accords on April 20, 2026, becoming the 62nd nation to join this American alliance in space.

The Republic of Latvia will sign the Artemis Accords during a ceremony at 9 a.m. EDT Monday, April 20, at NASA Headquarters in Washington. NASA Administrator Jared Isaacman will host Dace Melbārde, Latvia’s minister for education and science; Jānis Beķeris, chargé d’affaires at the Embassy of the Republic of Latvia to the United States; and Jacob Helberg, under secretary of state for economic affairs at the U.S. Department of State.

With this signing, all three of the Baltic states that were once occupied and part of the Soviet Union have now joined this American alliance. So have the former Soviet provinces of the Ukraine and Armenia, as well as the nations of Bulgaria, Czech Republic, Slovakia, Hungary, Poland, Romania, and Slovenia, all of which were once part of the Soviet Bloc, behind the Iron Curtain. In fact, almost all of Russia’s neighbors in Europe have allied themselves with the U.S. Artemis space alliance. It does appear that Putin’s stupid effort to recapture the Ukraine has backfired badly, encouraging these nations to come to us out of fear of the aggressive tyrant on their borders. These nations also probably recognize that Russia’s space effort is a Potemkin Village, hollow and of little worth. If they want to go to space, they need to align themselves with American technology.

The full list of all signatories to this American space alliance:

Angola, Argentina, Armenia, Australia, Austria, Bahrain, Bangladesh, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Israel, Italy, Japan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malaysia, Mexico, the Netherlands, New Zealand, Nigeria, Norway, Oman, Panama, Peru, Poland, Portugal, Romania, Rwanda, Saudi Arabia, Senegal, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the Philippines, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

The movement of surface ash on Mars over a half century

12:08 pm

Viking and Mars Express images side-by-side for comparison
Go here and here for original images.

Overview map

Cool image time! In comparing images of one location on Mars taken a half century apart, scientists using Europe’s Mars Express orbiter have discovered that the dark ash covering this region has shifted south by about 200 miles.

The two images above show the change, with a Viking orbiter image taken sometime in 1976 on the left and the Mars Express image taken in 2026 on the right. Both images have been enhanced to match each other, with the white box marking an area seen in close-up by Mars Express.

The overview map to the right provides the context. This region is inside Utopia Basin, one of the largest ancient impact basins on Mars, thought to have been formed by an impact that occurred a little more than four billion years ago. Much of Mars’ dark volcanic dust is thought to come from the Medusae Fossae Formation, a gigantic volcanic ash field the size of India and located on the other side of the planet, in between all of the red planet’s largest volcanoes. Over the eons that ash has gotten distributed across the globe.

In this case, it not only covers large areas of Utopia Basin, but over a half century the prevailing winds in the thin Martian atmosphere has been enough to shift the edge of this particular ash field south by 200 miles.

New data from Webb suggests two of Uranus’ outer rings are starkly different

The outer two rings of Uranus as seen by Webb in the infrared

Using new infrared data obtained by the Webb Space Telescope in February 2025 and combined with optical data previously obtained by the ground-based Keck Observatory in 2007 and the Hubble Space Telescope in 2003 and 2013, astronomers now think that two adjacent outer rings of Uranus are completely different from each other, with one ring largely created by icy material thrown off the moon Mab.

The infrared image to the right was taken by Webb, and shows the two subject rings, dubbed v and μ.

Though they orbit the same planet, Uranus’s μ and ν rings are fundamentally different. Prior observations with the combined Keck Observatory and HST showed that the μ ring appeared blue, a signature of extremely small particles, while the ν ring’s reddish hue points to a more typical dusty ring. Why the rings were so different remained a mystery, though.

When JWST came on-line and observed Uranus, the research team used all its data, taken at different infrared wavelengths, in combination with Keck Observatory and HST observations to construct a complete spectrum from the visible through to infrared. By analyzing how sunlight reflects off the rings, the team identified a strong absorption feature near a wavelength of 3 microns (3 millionths of a meter) visible in the infrared for both rings. Beyond that shared feature, the differences become clear when simulating the detailed spectra: the μ ring closely matches the spectral signature of water ice, while the ν ring is clearly composed of rocky material, mixed with approximately 10–15% carbon-rich organic compounds commonly found in the outer solar system.

The μ ring seems to be made up of tiny icy grains knocked off the planet’s small (12-km sized) moon, Mab, by micrometeorite impacts. Interestingly, the icy composition of the μ ring also confirms that the moon Mab is composed mostly of water-ice.

According to the paper’s abstract, the v ring is dusty and, “like typical dusty rings, is sourced from collisions between, and micrometeoroid impacts on, larger but as yet unseen parent bodies orbiting within this ring. These bodies must be composed in part of organic materials [molecules with carbon as one component].”

This data really only raises more questions than it answers. For one, what are those larger objects within the v ring? Without a nearby orbiter there is no way to find them. For another, this new data really doesn’t explain why these two adjacent rings are so different. What processes force such a distinct distribution of materials?

India’s space agency: In ’25 it did 20 maneuvers to avoid collisions in space

10:29 am

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

India’s space agency ISRO today released its annual Space Situational Report, describing the collision possibilities that now exist due to the large increase in orbiting objects. According to this report, in 2025 ISRO did 20 maneuvers to avoid collisions in space.

More than 150,000 alerts issued by the Combined Space Operations Center (CSpOC) of USSPACECOM for ISRO’s Earth orbiting satellites were analysed using more accurate orbital data from operational flight dynamics. There were 4 collision avoidance maneuvers (CAM) for GEO [geosynchronous orbits], while 14 CAMs, including one for NISAR [A NASA/ISRO radar telescope], which is designated as Risk Mitigation Maneuver in NASA terminology, were performed for LEO [low Earth orbiting] satellites. Wherever feasible, collision avoidance requirements were met by adjusting orbit maintenance maneuvers to avoid exclusive CAMs.

In addition, ISRO had to twice shift the orbit of its Chandayaan-2 lunar orbiter because of an orbital conflict with NASA’s Lunar Reconnaissance Orbiter (LRO).

The report has a lot more interesting details, as ISRO is also trying to increase its ability to track everything in orbit, rather than rely on data from the American military or American commercial tracking companies, which has been the policy in the past.

Saxavord spaceport faces new regulatory and financial issues

9:19 am

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

The long-delayed Saxavord spaceport on the Shetland Islands in Great Britain appears to now face two new problems that could block future launches, one regulatory and the second financial.

First the financial issue: The spaceport, which has lost about $7 million in both ’23 and ’24, appears to be in technical default of a loan of a bit more than $14.3 million. In this case, the lender is willing to ignore the technical issue, assuming the spaceport meets certain conditions presently being negotiated.

The regulatory issue however is more serious, and could block the spaceport’s expected first launch later this year by the rocket startup Rocket Factory Augsburg.

Despite claiming to be ready for launch, the spaceport has also been subject of a formal complaint to the SIC [Shetland Islands Council] over allegations that the facility has not yet been granted a completion certificate or approval for occupation. The complaint alleges that the fire detection and alarm systems appear not to have been installed and that the premises may be in use without adequate fire precautions. It asks the council to confirm whether the premises has been subject to regulatory oversight and whether it has undertaken an inspection of the site.

The SIC said in response: “Concerns have been raised with the council and these are being looked at by our building standards service. A site inspection is scheduled this week as part of the live building warrant process, including to establish the current position in relation to the building on the site that falls within the council’s building standards remit. Any further action will be considered in light of the findings of that inspection.”

In other words, if the local council finds the fire detection and alarm systems not installed and within its regulatory responsibility, it will deny Saxavord its launch permit.

Meanwhile, the spaceport has been trying for years to get other rocket companies interested in using Saxavord, to no avail. Rocket startups have enough difficulties. They quite rightly don’t need the added delays caused by the UK’s red tape, delays that contributed to the bankruptcy of two different rocket startups. For example, most of the regulatory delays — lasting years — have initially come from a variety of national agencies, with Great Britain’s Civil Aviation Authority leading the way. This new issue is local, an additional bureaucratic layer that must be satisfied.

Vast unveils a proposed docking port more than 3x larger than standard space station ports

8:01 am

Vast's larger port compared to standard ports now used at ISS
Click for short movie.

The space station startup Vast yesterday unveiled its proposed Large Docking Adapter, designed to provide a docking port more than three times wider than the standard space station ports presently used on ISS.

The image to the right provides an clear comparison. The two smaller ports on the left are presently used on ISS. Vast’s new port is on the right.

Vast, the company developing next-generation space stations, announced today at the 41st Space Symposium the Large Docking Adapter, including its current development, its availability for purchase, and Vast’s plans to open-source its interface.

Future space stations will use larger modules, have greater overall mass, and dock with a new generation of bigger crewed vehicles. New docking standards and universal hardware are required for the future generation of space vehicles and habitats. The Large Docking Adapter is engineered to support higher mass and increased structural demands while enabling varying types of modules and vehicles to dock together. By open-sourcing the interface, slated for May 2026, Vast is intending to encourage industry-wide collaboration and accelerate the development of interoperable space systems.

Animations of the adapter at this Vast website suggest strongly that the company wants to encourage SpaceX to use the adapter on Starship. Since the company is releasing the design as open-source, it also wants everyone to use it as the standard.

Such a port could also be used on a variety of other spacecraft designs presently under development, and if used would enhance their capabilities significantly.

Voyager wins slot to fly tourist mission to ISS in 2028

Starlab design as of December 2025
Starlab design as of December 2025

NASA today announced that it has awarded Voyager Technologies a slot to fly a tourist mission to ISS in 2028.

The mission, named VOYG-1, is expected to spend as many as 14 days aboard the space station. A specific launch date will depend on overall spacecraft traffic at the orbital outpost and other planning considerations.

Voyager 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 the launch provider for their flight.

Voyager is the lead company in the consortium that is building the Starlab station, a single very large module to be launched on SpaceX’s Starship.

At this moment three of the five commercial stations that are developing private space stations — Axiom, Vast, and Voyager — now have deals to fly such missions to ISS. The two remaining likely didn’t pass muster with NASA, for different reasons. Max Space is a late comer to this competition, only declaring that it is building its own station this year. Orbital Reef, led by Blue Origin and Sierra Space, is apparently a dead project, with neither company doing anything to sell its project for the past year or so.

In my rankings below of the five American commercial space stations presently in development, the first three are essentially tied at this point.

Sweden’s space agency signs cooperative licensing agreement with the FAA

The Swedish Space Agency has signed a cooperative licensing agreement with the FAA to help facilitate orbital launches by American rocket companies from its Esrange spaceport.

While the Esrange Space Centre has been in operation since the 1960s, it has strictly been used for suborbital flights. In 2023, SSC Space, the commercial operator of the facility, inaugurated a new launch complex at Esrange to support orbital missions. While the facility has yet to host a launch, South Korea’s Perigee Aerospace and US launch provider Firefly Aerospace have both committed to using it in the future.

Sweden’s efforts to enable US rocket launches from Esrange took another step forward on 15 April 2026, as the Swedish National Space Agency signed an agreement with the FAA to coordinate the licensing of those missions. The agreement builds on a 2025 Technology Safeguards Agreement between the two countries, which laid the groundwork for US launch providers to export what the US government considers “advanced space technology” to Sweden.

Esrange’s interior location remains a problem, however. Any orbital launch is going to have to fly over other countries, either Finland, Russia, or Norway, and it remains unclear whether those countries will approve. Norway has already expressed opposition.
