More “Fluvial Processes” on Mars

12:59 pm

More fluvial processes on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 4, 2026 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists label this “Fluvial processes inside crater,” an apt description based not only on the small section of the full image to the right, but on the full image itself. The entire surface of the crater floor’s western end appears filled with glacial material, in many places twisted and warped by past slow motion movements.

I picked out the area in the picture because of its particularly warped nature. It appears as if the material in the higher elevations to the upper right have been flowing downward, and in the process have pushed the glacial debris on the crater floor to the southwest.

It also appears that in the higher locations the near surface ice has been sublimating away, giving the surface a corroded look.

Vantor’s 10-satellite imaging constellation now providing high resolution 3D pictures

10:16 am

The Arc de Triomphe in Paris

The satellite company Vantor is now offering high resolution 3D imagery from its 10-satellite constellation at resolutions in some cases able to see objects as small as six inches across.

The Vantor image to the right of the Arc de Triomphe in Paris has such a resolution.

The product is available through two options designed for different mission needs:

  • Rapid 3D: Designed for time-sensitive missions where terrain conditions can change quickly, this product delivers updated 3D terrain within 24 hours of image collection with just a single satellite pass. Accessible via Vantor™ Hub, it delivers 50 cm-class resolution and 4 m accuracy in all dimensions.
  • High-definition (HD) 3D: Designed for missions that require greater fidelity, this product provides detailed 3D maps at 15 cm resolution and 3 m accuracy in all dimensions. Available globally on a project basis, this capability can also be delivered through change-based refresh subscriptions for customers who need to monitor terrain and infrastructure over time.

The company began launching its 10-satellite constellation in 2024 under the ownership of Maxar. In 2025 the Maxar Intelligence division running the project was rebranded Vantor. Its constellation “can revisit the same location on Earth 15x per day, with downlink speeds as fast as 15 minutes after collection.”

The commercial and military possibilities of this technology can hardly be measured. I also suspect that Vantor and the War and State departments have a close working relationship as to the release of this data and who can get it.

Vantar is also once again demonstrating the advantages of freedom, competition, and capitalism. A decade ago the military struggled to build on its own such imaging constellations. Little got built, though budgets ballooned. Since it shifted to the capitalism model, hiring private companies to do the work, it has gotten it done fast, cheap, and with capabilities the military couldn’t dream of in the past.

Private company Auxilium Biotechnologies successfully prints kidney and liver tissues on ISS

9:51 am

The private company Auxilium Biotechnologies today announced it has successfully printed kidney and liver tissues as well as manufactured 28 nerve implants during a recent mission on ISS.

During the mission, Auxilium’s AMP-1 orbital bioprinter successfully manufactured kidney, liver, and cartilage tissues while also producing 28 nerve repair implants. The achievement represents the first demonstration of kidney tissue manufacturing in space, the first demonstration of liver tissue manufacturing in space, and the first mission to manufacture three distinct tissue types during a single spaceflight. The production of multiple tissue types and clinically relevant nerve repair implants represents the first demonstration of a scalable, multi-product biomanufacturing platform in space.

Equally important, the mission demonstrated the ability of a single autonomous manufacturing platform to produce both living tissues and implantable medical products during the same flight. The simultaneous production of multiple tissue types alongside 28 nerve repair implants highlights not only the versatility of the platform, but also its scalability and higher-throughput manufacturing in space.

Because NASA forbids the manufacture of any products on ISS for sale later, this experiment by Auxilium is merely a demonstration of the technology. The company however already has a deal to do this work on Vast’s space stations, and appears in negotiation with the Starlab space station as well. Once those private stations launch, it is now certain that Auxilium will rent space on those stations to begin production and sale of these medical products.

In other words, these space stations have a growing and viable customer base, outside of NASA and the government.

Blue Origin to seek private funding beyond Jeff Bezos

9:39 am

For the first time Blue Origin now intends to raise additional outside private funding, $10 billion total, beyond the billions Jeff Bezos has been investing in company for the past decade.

In a memo sent to employees on Wednesday and seen by Business Insider, Blue Origin CEO Dave Limp said the company would raise [$10 billion in] funds at a $130 billion valuation.

…The New York Times’ DealBook earlier reported on the raise and said it is being led by asset management firm Coatue Management with a $2 billion contribution from Bezos.

By my count in 2020, Bezos had pumped somewhere between $2 to $6 billion into Blue Origin, the funds coming from sales of his Amazon stock beginning in 2017. With this new investment round, he will have committed another $2 billion.

Unlike the earlier funding from Bezos, however, this new investment is occurring with Limp as the company’s CEO. When the previous funding occurred the company’s CEO was Bob Smith, who essentially wasted more than five years from 2017 to 2023 accomplishing nothing. No rockets got built, engine development was delayed endlessly, and good engineers were seen fleeing the company. Since Limp took over in 2024 he has aggressively worked to change the moribund culture he inherited from Smith. Under his leadership this funding could really make a difference.

Rocket engine startup Venus Aerospace raises $91 million in investment capital

9:13 am

Following a successful suborbital test flight of its rotating detonation rocket engine (RDRE) in May, the rocket engine startup Venus Aerospace has now raised an additional $91 million in private investment capital, on top of $80 million raised previously.

Venus Aerospace today announced the close of a $91 million Series B financing led by Mercury Fund, a Houston-based venture capital firm, with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity, Seraph Group, Trousdale Ventures, and other new and existing strategic and institutional investors.

…Unlike conventional rocket engines, which burn fuel through subsonic combustion,Venus’ RDRE employs a continuous supersonic detonation wave that rotates around the combustion chamber. The result is the most efficient rocket engine architecture ever flown, by a margin of 15 percent.

The company intends to develop the engine for sale to many rocket companies and across many platforms. It already had a significant investment from Lockheed Martin, which tested its own RDRE engine in January 2026.

SpaceX launches 29 more Starlink satellites; flies first stage for 36th time

8:42 am

SpaceX last night successfully launched another 29 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral Space Force station in Florida.

The first stage (B1067) completed its 36th flight (31 days after its previous mission), landing on a drone ship in the Atlantic. With this flight this booster maintained its second place position, behind the space shuttle Discovery, in the rankings for the most reused launch vehicle:

39 Discovery space shuttle
36 Falcon 9 booster B1067
34 Falcon 9 booster B1071
33 Atlantis space shuttle
33 Falcon 9 booster B1063
31 Falcon 9 booster B1069
29 Falcon 9 booster B1077
29 Falcon 9 booster B1078

Sources here and here.

The leaders in the 2026 launch race:

82 SpaceX
44 China
10 Rocket Lab (plus two suborbital HASTE launches)
8 Russia

For the third straight year SpaceX leads the entire world combined in total launches, 82 to 76.

China will attempt the first launch of its reusable Long March 10B tonight. The first stage is designed to be reusable, but instead of landing vertically on its recovery vessel in the ocean, it will be descend horizontally and be caught by a netting system on the ship.

Anton Karas – Theme from the Third Man

6:01 pm

An evening pause: The movie, The Third Man (1949), was directed by Carol Reed and starred Orson Welles. This theme, played throughout, made the film something special. This live performance is from 1950. I like especially how it shows so clearly the intricate finger play.

Bright spokes in Saturn’s rings

11:46 am

Bright spokes in Saturn's rings
Click for original image.

Cool image time! The picture to the right, cropped slightly to post here, was taken on December 26, 2008 from a distance of 350,000 miles by the Cassini spacecraft as it orbited Saturn. The resolution is about 37 miles per pixel.

I think sunlight is coming from the upper left, its light bouncing off the rings and thus making the those spokes bright and visible.

In the viewing geometry in which Cassini is looking approximately in the direction of the sun (called high phase), the spokes appear white against the rings because the very small particles comprising the spokes preferentially scatter light forward (in this case, toward Cassini).

At least that’s one theory for explaining the spokes that appear randomly and for only short periods within Saturn’s rings, sometimes bright, sometimes dark, depending on the angle of the Sun. According to a Hubble press release from 2023, the spokes are formed due to an interaction between Saturn’s magnetic field, the solar wind, and the tiny particles in the rings.

“The leading theory is that spokes are tied to Saturn’s powerful magnetic field, with some sort of solar interaction with the magnetic field that gives you the spokes,” said Simon. When it’s near the equinox on Saturn, the planet and its rings are less tilted away from the Sun. In this configuration, the solar wind may more strongly batter Saturn’s immense magnetic field, enhancing spoke formation.

Planetary scientists think that electrostatic forces generated from this interaction levitate dust or ice above the ring to form the spokes, though after several decades no theory perfectly predicts the spokes. [emphasis mine]

Just another strange alien phenomenon in space that remains unsolved. All we really know is that the spokes appear, remain visible for at most a rotation or two of the rings, and then disappear.

Japan’s Ispace signs deal with SpaceX to use Starship for lunar cargo delivery

9:14 am

Ispace's mobile cargo system
Click for original.

The Japanese lunar lander startup Ispace yesterday announced it has signed an agreement with SpaceX to use its Starship lunar lander to transport cargo to the Moon’s surface.

The Ispace graphic to the right shows the company’s proposed “Mobile Cargo System” on the Moon after deployment from Starship.

In preparation for the new business offering, Ispace has secured 500 kilograms of payload capacity on Starship, scheduled for launch as early as 2030. Ispace is offering global customers with relatively small payload delivery needs, weighing 500 kilograms or less, a comprehensive service to integrate, transport and operate their payloads on the Moon.

As part of the integration process, Ispace will assess each customer’s payload requirements and implement the quality control necessary for lunar transportation. Ispace will then integrate multiple payloads into the dedicated “Mobile Cargo System” in development by the company and provide services, including interface coordination with Starship as part of the system. Upon landing on the Moon, Ispace aims to provide operational support through the “Mobile Cargo System” to ensure the smooth deployment of payloads onto the lunar surface, their movement across the lunar surface, and access to other infrastructure.

Ispace is clearly hoping this cargo system will be of interest to NASA for its Moonbase project. It is also something that will appeal to other commercial customers who want to get a payload to the Moon cheaply.

Satellite company Loft Orbital signs multi-launch deal with European rocket startup Maiaspace

8:59 am

Because it appears SpaceX is ending its multi-payload Transporter Falcon 9 launches for smallsats after 2028, the satellite company Loft Orbital has now signed multi-launch deal with European rocket startup Maiaspace.

Although the announcement provided few details, it did share that the first flight was expected in 2028. In an 8 July press release, MaiaSpace explained that the multi-launch agreement “consolidates its launch manifest,” adding that the company has now sold more than half of all capacity for its first three years of operation.

To date, all Loft Orbital satellites have been launched aboard SpaceX Transporter rideshare missions. However, according to reporting from SpaceNews, in recent weeks, several customers of these missions have said that SpaceX is not accepting Transporter reservations beyond late 2028 or early 2029. The publication quoted Rocket Lab CFO Adam Spice as saying that there “seems to be a panic setting in.”

If the SpaceX aspect of this story is true, it means there will now be a slew of new satellite customers for all the many rocket startups, not just Maiaspace. In fact, it is puzzling Loft Orbital went to Maiaspace first. That company does not expect to do its first orbital test flight until late ’27. Meanwhile the Spanish startup PLD, the Indian startup Skyroot, the South Korean startup Innospace, the German startups Isar and Rocket Factory, and the American startups Stoke Space and Relativity are all expected to try their first launches before the end of this year. In addition, Rocket Lab has its Electron rocket, and hopes to launch its new Neutron rocket also by the end of this year.

That SpaceX is no longer taking reservations for Transporter flights after late 2028 also gives us a hint as to the company’s future plans for its Falcon 9 rocket. There has been much speculation it would be replaced by Starship, and this news suggests that transition from Falcon 9 to Starship is now beginning.

Saxavord approves August launch window for Rocket Factory Augsburg

8:40 am

Proposed or active spaceports in north Europe
Proposed or active spaceports in north Europe

The Saxavord spaceport yesterday announced it has approved a five week launch window beginning on August 10, 2026 during which the German startup Rocket Factory Augsburg will be permitted to attempt a launch of its RFA-1 rocket.

SaxaVord Spaceport said the launch window was designed to minimise disruption to everyday life in Unst while maintaining the highest safety standards. The window spans five weeks from Monday 10 August, but restrictions will not be in place continuously throughout that period. Instead, potential launch attempts can only take place on Mondays, Wednesdays and Fridays between 4pm and 8pm.

In April Rocket Factory had applied for a launch window opening on July 1st. As expected, Saxavord did not give it, likely because of regulatory demands by the United Kingdom’s Civil Aviation Authority (CAA). It appears the CAA had in 2024 required Saxavord to put in a perimeter fence surrounding the facility, and it had not done so. Last week the spaceport announced it would spend more than $100K to install the fence. I suspect this last delay is to give it time to do the work.

The launch itself will be Rocket Factory’s first attempt. In 2024 it was gearing up for a launch, but an explosion during the last static fire test of the first stage destroyed the stage and damaged the pad.

If this launch occurs as planned, it will end almost a decade of delays at Saxavord, almost all of which the result of red tape from the CAA. As a result, though Saxavord had a significant head start on the other spaceports shown on the map above, it remains uncertain whether it or Norway’s Andoya spaceport will achieve the first successful launch. The German rocket startup Isar Aerospace has been trying to launch from Andoya since last year. Its first attempt in 2025 was a failure, and its second attempt has been scrubbed three times since January. A new launch attempt is tentatively scheduled for later this month.

Firefly to build descent aeroshell for NASA’s Mars Skyfall helicopter mission

8:01 am

Skyfall concept
SkyFall helicopter deployment. Click for original animation.

In a press release yesterday, Firefly Aerospace announced it has won a $13 million contract to build the descent aeroshell that will be used to protect the three Ingenuity-class helicopters being sent to Mars in 2028 on NASA’s proposed Skyfall mission.

The SkyFall aeroshell, comprising both the backshell and heatshield, will be developed within Firefly’s new Gloworks innovation lab and manufactured at the company’s Rocket Ranch in Briggs, Texas. Firefly will utilize advanced carbon composite technologies from its proven Blue Ghost lunar landers, Elytra orbiters, and Alpha and Eclipse launch vehicles to rapidly produce high-strength, lightweight structures.

This press release provides the most details yet about the mission. The graphic to the right is a screen capture from a video from JPL, showing the mission concept. First the helicopters would descend through the Martian atmosphere encapsulated in Firefly’s aeroshell. The bottom half would then drop off, and parachutes would release from above. Once close to the ground, the helicopters would be lowered out of the shell on the frame shown to the right, turn on their rotors, and then be released to fly away and land on their own.

This technique utilizes an entry capsule to release the three helicopters during descent, eliminating the need for a landing platform. The helicopters will then fly to the surface and capture high-resolution surface imagery and subsurface radar data.

We still do not know the chosen landing location on Mars, though the press release mentions a search for water ice, suggesting it will not be in the dry equatorial regions, where almost all landers and rovers have gone, but in mid-latitudes or higher where glaciers and lots of near surface ice has been detected.

The mission is intended after launch to use the nuclear propulsion engines NASA is developing jointly with the Energy Department to get to Mars. I remain skeptical those engines will be ready by 2028.

The empty desolation west of Jezero crater

2:07 pm

The empty desolation west of Jezero crater
Click for full resolution image. For original images go here and here.

Overview map
Click for interactive map.

Cool image time! The panorama above was created from two pictures taken on July 1, 2026 (here and here) by the left navigation camera on the Mars rover Perseverance.

The overview map to the right provides the context. The white dotted marks the rover’s travels, with the blue dot marking Perseverance’s last posted location as of July 6, 2026. The yellow lines indicate roughly the area viewed by the panorama, taken five days earlier at a previous location.

The panorama looks west, at a low ridge line about 1,000 feet from the rover (the white dot), with a distant hill beyond (the black dot), about 4,500 feet away. The ridge is only about 50-60 feet high, while the hill rises about 600 feet. The rover’s tracks can be seen on the left.

Once again, the view from Perseverance indicates starkly the lifeless nature of Mars. Maybe it once had microbiology (though this is certainly not indicated so far by any solid evidence), but if it did, it is long long gone, and in fact likely never prospered at this location at all. NASA might claim repeatedly that Perseverance’s mission is to search for life, but every geologist on the mission knows this is a very low priority. What they are doing is studying the alien geology of another world. This image gives one a hint of its alienness.

Most specifically, Perseverance is studying a region in the dry tropics of Mars, where no near surface water remains, but also carries ample evidence of potentially valuable mineralogy. Orbital data strongly suggests the region west of Jezero crater will become a major mining region for future settlers. It might not contain any life, but it carries resources that will sustain the life that is soon to come from Earth.

The Perseverance team has been scouting this region now for the last four months, without doing any additional drilling. In fact, the last drill samples were taken at Witch Hazel Hill, in the spring of 2025. It appears they are taking their time to look for the best place to get core samples.

NASA wants its future space telescopes designed to be serviceable, like Hubble

11:04 am

In a briefing at a recent science conference, a NASA official made it clear that it wants its proposed Habitable Worlds Observatory (HWO) — presently undergoing its initial design studies for launch in the 2040s — be designed in a way that it can be maintained, repaired, and upgraded, much like the Hubble Space Telescope.

NASA is planning for HWO to be serviceable, which means that they will need to figure out a way to work on, repair, and maintain the observatory while it operates roughly a million miles (1.5 million kilometers) away. “HWO will have to be serviceable to some extent,” NASA’s astrophysics division director Shawn Domagal-Goldman told Space.com during a session at the American Astronomical Society’s (AAS) 248th meeting in Pasadena, California.

This design decision not only makes sense, NASA should have made it common practice a decade ago. The ability for robots to do this work is becoming increasingly robust, and in the next decade will become commonplace. For NASA to have launched anything in the past decade without this in mind was shameful.

Scientists tighten the protocols for announcing any evidence of alien life

10:56 am

New protocols developed by Search for Extraterrestrial Intelligence (SETI) project and approved by the International Academy of Astronautics (IAA) now tighten significantly what the scientific community is expected to do if anyone detects evidence that might be extraterrestrial life.

You can read the full protocols here [pdf]. From the press release:

At the heart of the new rules is a reaffirmation of a core scientific principle: “extraordinary claims require extraordinary evidence.” Under the revised protocols, no public announcement should be made until a signal or artifact has been rigorously authenticated by independent organisations using different instrumentation.

“We do not shout “alien” the moment we see a strange blip,” Garrett added. “The scientific method demands we check, check again, and then ask others to check. Only when we have reached a consensus that a signal is credible do we bring it to the world.”

SETI’s press release notes this rule is necessary due to the modern nature of social media, which allows the wildest claims to be spread like poison almost immediately. As noted in this story, the new rules almost appear to be a direct slap at hack Harvard scientist Avi Loeb, who with both interstellar objects Oumuamua and Comet 3I/Atlas claimed evidence of alien technology when there was no evidence to say so.

The new rules also underline a second point: Under no condition will any scientist attempt to reply or contact any potential alien source. “The Declaration reaffirms the enduring principle that transmitting a response to an extraterrestrial intelligence is a decision that belongs to all of humanity and should only take place following international consultations, specifically through the United Nations.”

It will be impossible for the science community to enforce this rule, but by stating it they hope to encourage scientists to exercise more caution, and further ostracize those like Loeb who do not. I remain skeptical, especially because it will have no influence on government agencies like NASA, which love to scream “We have found alien biology!” at the slightest hint. Nor will it influence the public, which seems determined to accept such wild claims with no skepticism at all.
