French startup The Exploration Company completes first splashdown tests of Nyx capsule prototype

9:31 am

The French cargo capsule startup, The Exploration Company, has successfully completed the first splashdown tests of a smallscate prototype model of its proposed Nyx capsule.

On 5 February, The Exploration Company announced that it had successfully completed a splashdown test campaign at the National Research Council’s Institute of Marine Engineering (CNR-INM) in Rome.

A 1:4-scale mockup of Nyx, with a mass of around 135 kilograms, was built for the test campaign by Poli Model, a small Turin-based model builder. For reference, the full-scale capsule will be 4 metres wide and stand at 7 metres tall. The subscale model’s exterior was fitted with pressure sensors, accelerometers, and a gyroscope.

The tests were conducted in the CNR-INM facility’s Umberto Pugliese towing tank, a 470-metre-long pool measuring 13.5 metres across and 6.5 metres deep. Between 13 and 28 January, a total of 20 drops were conducted at varying heights and speeds in calm water, which the company explained maximised repeatability.

The company hopes to fly a fullscale demo mission to ISS in 2028, and wants to upgrade Nyx to manned capabilities in the 2030s.

Israeli weather satellite startup raises $175 million in investment capital

9:17 am

An Israeli weather satellite startup, dubbed Tomorrow.io, has now raised $175 million in investment capital to build an AI-driven constellation of satellites to supplement the smallsat constellation it has already launched.

This financing builds on a proven foundation of execution. Tomorrow.io has completed the full deployment of its first satellite constellation, having launched 13 satellites to space, achieving 60-minute global revisit, while scaling an AI-driven intelligence platform now embedded across critical industries. DeepSky extends this foundation into the next phase of the company’s roadmap, supporting continued commercial growth, expanding data coverage, and unlocking new high-frequency sensing capabilities.

I find amusing this new desire to label all computer programming “AI”, when in many cases it is simply the same software slightly upgraded that these companies have been using for years.

Nonetheless, this story signals the continuing transition in the weather satellite industry from the government/Soviet-style model, where all weather satellites are built and operated by governments, to the capitalism model, where governments and industry buy weather data from privately built, launched, and maintained commercial constellations.

Using NASA’s SphereX infrared space telescope, astronomers have now detected a range of new molecules in the coma surround interstellar Comet 3I/Atlas as that coma brightened and grew in December 2025 following the comet’s closest approach to the Sun in the fall.

You can read the research paper here. From the press release:

In a new research note, mission scientists describe the detection of organic molecules, such as methanol, cyanide, and methane. On Earth, organic molecules are the foundation for biological processes but can be created by non-biological processes as well. The researchers also note a dramatic increase in brightness two months after the icy body had passed its closest distance to the Sun, a phenomenon associated with comets as they vent water, carbon dioxide, and carbon monoxide into space.

In every way this interstellar object continues to behave like an ordinary comet, which is actually quite profound. It tells us the rest of the universe is not that different than our solar system.

German rocket startup Isar Aerospace opens new rocket testing facility at Esrange spaceport

8:03 am

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

Though the German rocket startup Isar Aerospace is using Norway’s Andoya spaceport to launch its Spectrum rocket, it is now expanding significantly its testing facilities at Sweden’s Esrange spaceport to the east.

European space company Isar Aerospace is significantly expanding their testing operations with SSC Space at Esrange Space Center in Sweden, opening a second test site to support the development and production of its ‘Spectrum’ rocket. The new facility will enable testing of 30+ engines per month, along with expanded integrated stage testing capabilities, increasing testing capacity and enabling faster development.

Launching from Esrange is a problem because of its interior location, but testing engines there, close to Germany and the Andoya spaceport makes great sense.

Isar had hoped to make its second attempt to complete the first orbital launch of Spectrum in January, but postponed the launch until March to deal with a valve issue.

Midnight repost: Truth, Justice, and the American Way

11:58 pm

Tonight Diane and I decided to watch again the 1978 Richard Donner movie, Superman. The overall film is lighthearted entertainment that captures the myth of this super-hero perfectly. However, it has two scenes that remain among the best moments in movie history (which you can watch here and here). The first captures the myth in every way. The second shows us that Superman truly stood for the best in America.

In watching the movie tonight again and reliving the myth I grew up with — that great things are possible if you believe and follow sincerely Superman’s motto of “truth, justice, and the American way” — I decided to repost my essay from 2020 where I attempted to explain what that motto really meant.

Enjoy!

Truth, Justice, and the American Way

The words spoken during the opening credits of a 1950s children’s television show:

Faster than a speeding bullet.
More powerful than a locomotive.
Able to leap tall buildings in a single bound.
Look up in the sky!
It’s a bird.
It’s a plane.
It’s Superman!

Yes, it’s Superman, strange visitor from another planet who came to Earth with powers and abilities far beyond those of mortal men.

Superman, who can change the course of mighty rivers, bend steel in his bare hands, and who, disguised as Clark Kent, mild-mannered reporter for a great metropolitan newspaper, fights a never-ending battle for truth, justice, and the American Way.

That television show was obviously Superman, starring George Reeves, and these opening words expressed the mythology and basic ideals by which this most popular of all comic-book super-heroes lived.

I grew up with those words. They had been bequeathed to me by the American generation that had fought and won World War II against the genocidal Nazis, and expressed the fundamental ideals of that generation.

Much of the meaning of these fundamental ideals is outright and clear.

SpaceX wants revisions to federal rural grant program that has awarded it $733 million

4:05 pm

SpaceX is presently asking for changes in the Broadband Equity Access and Deployment (BEAD) program that awards grants to companies that provide internet in rural areas and has already awarded the company $733 million in grants.

BEAD was part of the Biden administration’s bipartisan infrastructure act – originally a $42 billion program to bring broadband internet to areas of the country with little or no broadband access. The Trump administration eliminated other infrastructure act programs, and cut BEAD outlays to $21 billion, along with rule changes to allow satellite providers.

SpaceX applied for BEAD funds in 2025. The company won $733 million worth of BEAD projects nationwide, including $109 million in Texas.

Initially the Biden administration awarded SpaceX almost a billion dollar grant, because its Starlink constellation was the only broadband outlet actually doing the job. Then Musk began to campaign for Republicans, and suddenly the Biden administration pulled that grant, saying absurdly that SpaceX was failing to provide its service to rural areas, when that was exactly what it was doing.

Now SpaceX wants BEAD to ease some of its requirements, and wants these grant funds upfront.

I say, this whole BEAD program is a waste of taxpayer money and a perfect example of crony capitalism. I’m glad Trump cut it in half, but that wasn’t good enough. It should be shut down entirely. SpaceX doesn’t need this handout. It is making money hand-over-fist on its own.

One of Saturn’s many weird moons

11:47 am

Saturn's moon Atlas
Click for original image.

Cool image time! The picture to the right, cropped and reduced to post here, was taken on April 13, 2017 by the orbiter Cassini as it began it last close loops around Saturn before diving into its atmosphere to burn up.

Those close loops allowed it to get good close-up images of a few of the tiny moons that orbit in or close to the gas giant’s rings. On the right is one of those pictures, of the moon Atlas, taken from a distance of about 10,000 miles.

The moon’s weird ravioli shape is thought to be caused by the accretion of dust and ice from the nearby rings along Atlas’s equator.

Scientists also found the moon surfaces to be highly porous, further confirming that they were formed in multiple stages as ring material settled onto denser cores that might be remnants of a larger object that broke apart. The porosity also helps explain their shape: Rather than being spherical, they are blobby and ravioli-like, with material stuck around their equators. “We found these moons are scooping up particles of ice and dust from the rings to form the little skirts around their equators,” Buratti said. “A denser body would be more ball-shaped because gravity would pull the material in.”

Atlas itself is about 25 miles wide and about 11.5 miles thick, at its thickest point. I suspect if you tried to walk on it you would sink into the accumulated dust and ice, as it is likely no more dense as newly fallen snow.

A nice summary of all space-based research of reproduction in space

10:12 am

Regulatory recommendations by these scientists
Click for original.

Link here to the press release. The paper itself can be read here.

The paper is an excellent summary of practically all the research that has been done in space and on the ground studying the impact of the harsh environment of space on reproduction. It notes above all that we really know very little despite this research, because the risks to the newborn have precluded direct study. From the paper’s abstract:

Despite over 65 years of human spaceflight activities, little is known of the impact of the space environment on the human reproductive systems during long-duration missions. Extended time in space poses potential hazards to the reproductive function of female and male astronauts, including exposure to cosmic radiation, altered gravity, psychological and physical stress, and disruption to circadian rhythm.

This review encapsulates current understanding of the effects of spaceflight on reproductive physiology, incorporating findings from animal studies, a recent experiment on sperm motility, and omics-based insights from astronaut physiology. Female reproductive systems appear to be especially vulnerable, with implications for oogenesis and embryonic development in microgravity. Male reproductive function reveals compromised DNA integrity, even when motility appears to be preserved. This review examines the limited embryogenesis studies in space, which show frequent abnormal cell division and impaired development in rodents.

In the paper’s conclusion, these academics sadly revert to type, and propose the establishment of an international regulatory framework for controlling this issue, as shown in the graphic to the right. This is empty foolishness, because such regulations will only do more harm than good, stifling research while failing to accomplish anything.

Commercial changes at France’s French Guiana spaceport

9:41 am

French Guiana spaceport

Ariane-6 pad.)

Once France’s space agency CNES regained control of its spaceport in French Guiana several years ago from the European Space Agency’s (ESA) commercial pseudo-company Arianespace, it has moved aggressively to make that spaceport attractive to the new European rocket startups.

Beginning in 2022, it began to sign deals with every one of those rocket startups to allow them to establish launch facilities at the spaceport using several long abandoned pads, including the French Diamant rocket site not used for decades as well as the Soyuz launch site unused due to Russia’s invasion of the Ukraine.

CNES decided to standardize Diamant for multiple rocket companies, while leasing the Soyuz site to one.

In a news story today, it appears the startup MaiaSpace, a wholly owned subsidiary of the much larger aerospace company ArianeGroupk, has shifted its launch plans at French Guiana. Initially it was going to launch its rocket from the Diamant pad. In 2024 however it won the contract to use the Soyuz pad, and it has now withdrawn its plans to use Diamant entirely.

CNES has therefore put out a call to the European rocket industry to fill this slot at Diamant. At present Isar Aerospace, PLD Space, Rocket Factory Augsburg, and Latitude have agreements to use Diamant, though only Latitude and PLD had done any development work on their facilities there.

As far as I know, these companies comprise the entire cadre of new European rocket startups, so I don’t know what other users CNES hopes to find. Furthermore, CNES had wanted to standardize the launch site for everyone, and the companies had balked at that idea. PLD got a deal to use its own pad at Diamant. I suspect the reason Isar and Rocket Factory have done little there is because they want their own facilities as well.

Either way, French Guiana is moving the direction of supporting competitive commercial operations, and that is a very good thing.
