Weird hatchwork at the Martian south pole

Cool image time! The picture to the right, cropped and rotated so that north is to the top, was taken on March 28, 2026 by the high resolution camera of Mars Reconnaissance Orbiter (MRO).

It shows what the science team labels a “south polar residual cap site.” The location is about 200 miles from the Martian south pole, well within the south polar ice cap. A second picture of this same spot was taken only a few days later, and was labeled “bright and dark fans on patterned ground.” With the second image the science team added their nickname for this location, “Troy,” which makes referencing it easier.

The hatchwork is the mystery here. In fact, the scientists have been monitoring this geology since 2020 to see if there have been any changes, either long term or seasonally. Almost certainly they have spotted seasonal changes, as indicated by the hatchwork itself and explained below, but I don’t access to the higher resolution images that would show any major modifications on a larger scale.

Psyche approaches Mars

8:30 am

Mars as seen by Psyche
Click for original image.

The asteroid probe Psyche is now approaching Mars for a May 15, 2026 fly-by that will slingshot it out to the metal asteroid Psyche in 2029.

The image to the right, cropped and expanded to post here, was taken on May 3, 2026 when the spacecraft was still about three million miles away.

The observation was acquired by the multispectral imager instrument’s panchromatic or broadband filter, with an exposure time of just 2 milliseconds. Even with this very short exposure time, the crescent is extremely bright and parts of the image are oversaturated. The light seen here is sunlight reflected off the surface of Mars and also scattered by dust particles in its atmosphere. Because the quantity of dust in the atmosphere can vary rapidly over time, the anticipated brightness of the crescent was hard to predict before this early image was acquired.

The dustiness of Mars leads to sunlight being scattered by its atmosphere, making the crescent appear to extend farther around the planet than if it had no atmosphere (as with our Moon).Of note, on the right side of the extended crescent, there appears to be a gap, which coincides with the planet’s icy north polar cap. The cap is currently in winter and mission specialists hypothesize that seasonal clouds and hazes may be forming in that region, possibly blocking the atmospheric dust’s ability to scatter sunlight like it does elsewhere around the planet.

Though the spacecraft had had a thruster issue last year, all seems well at this time.

China launches Tianzhou freighter to Tiangong-3 station

8:33 pm

China today (May 11th in China) successfully launched the tenth Tianzhou freighter to its Tiangong-3 space station, its Long March 7 rocket lifting off from its coastal Wenchang spaceport.

China hopes to keep this cargo freighter in orbit for a full year, as part of its effort to reduce the number of cargo missions per year while expanding the capabilities of its spacecraft and station.

The leaders in the 2026 launch race:

55 SpaceX
24 China
8 Russia
6 Rocket Lab

For the third straight year SpaceX leads the entire world combined in total launches, 55 to 45.

Vast signs deal with Lithuania

The space station startup Vast earlier this week signed an agreement with Lithuania to work together on future space missions, either to ISS or its Haven-1 single-module station scheduled for launch next year.

Under the agreement, Vast and Innovation Agency Lithuania will explore opportunities for joint scientific research activities either in the International Space Station National Lab or Haven-1, scheduled to be the world’s first commercial space station, launching in 2027. The partnership also includes plans to further develop educational programs in Lithuania and deepen engagement with local industry.

This deal is similar to Vast’s earlier deals with the European Space Agency, the Czech Republic, Colombia, Uzbekistan, Japan, and the Maldives. All are structured so that should Haven-1 reach orbit and be proven operational and safe for occupancy, these countries could consider sending their own astronauts on missions there. All thus show there is an international market for a private space station, a market that Vast is working hard to capture.

In other space station news, Voyager Technologies, the lead company building the Starlab station, released its 2026 first quarter fiscal report, indicating a solid financial position resulting from its diversification into military-based space applications. Though the report notes that “Starlab does not generate revenue today, nor is expected to generate revenue in the near term,” the company’s overall strength lays a strong foundation for that station’s eventual construction.

In my rankings below of the five stations under development, these two stations remain essentially tied for first place, with Axiom a close third.

Katalyst completes final ground testing of its Swift rescue spacecraft

The orbital servicing startup Katalyst has now successfully completed the final ground testing of its Swift rescue spacecraft, dubbed LINK, that it hopes will be able to catch the Gehrels-Swift Telescope and raise its orbit, thus saving the telescope.

During vibration testing at NASA Goddard, engineers mimicked the shaking the spacecraft will experience during its launch from a Northrop Grumman Pegasus rocket. In the footsteps of Swift itself and NASA’s upcoming Nancy Grace Roman Space Telescope, the Katalyst team also used NASA Goddard’s Space Environment Simulator for thermal vacuum testing.

Once the air was pumped out of this 27-foot-wide chamber, LINK experienced space-like hot and cold temperature extremes. The team also practiced firing the satellite’s three xenon-powered ion thrusters and deployed one of the arms.

After some more testing in Arizona, the spacecraft will be integrated in June onto Northrop Grumman’s Pegasus rocket — the last one in its inventory — and launched later that month.

Katalyst has never done this before. It was preparing LINK as a demo mission when NASA requested bids for saving Swift. It proposed reconfiguring LINK for that purpose, and won the contract in September 2025, only eight months ago.

If this mission succeeds it will be a big feather in Katalyst’s cap.

Rover startup Lunar Outpost raises $30 million in investment capital

10:08 am

The lunar rover startup Lunar Outpost revealed yesterday that it has raised $30 million in private investment capital in its latest funding round.

Lunar Outpost, the leader in off-planet mobility and in-space infrastructure, today announced a $30M Series B led by Industrious Ventures, with participation from Type One Ventures, Eniac Ventures, Promus Ventures, Reliable Equity, and others. The capital injection accelerates production and deployment of the company’s advanced robotics and mobility platforms as it scales the critical industrial layer required for a permanent human presence in space.

The company started out competing for NASA’s initial planned contract to build a manned lunar rover, proposing its “Eagle” rover and even signing a contract with SpaceX to deliver it to the Moon on Starship. Since then it has developed and successfully tested an autonomous excavator, dubbed Owl, while expanding its product line beyond rovers.

Rocket Lab gets big launch contract for both its Electron and new Neutron rocket

Rocket Lab announced yesterday that it has won a big new launch contract with an undisclosed customer for three launches of its Electron rocket and five launches of its new Neutron rocket.

The multi-launch agreement includes five dedicated Neutron launches and three dedicated Electron launches baselined to launch between 2026 and 2029. The missions will lift-off from both Rocket Lab Launch Complex 1 in New Zealand and Rocket Lab Launch Complex 3 in Virginia. Pricing for these launches aligns with Rocket Lab’s average selling price for Neutron and Electron. The remaining terms of the deal are undisclosed.

Based on the known average launch prices for these rockets, this deal is likely worth somewhere between $250 million to $300 million. That a customer was willing to purchase five launches of Neutron before the rocket has even launched is also a strong statement of confidence in Rocket Lab itself. The company hopes to do the first test launch of Neutron before the end of this year.

Rocket Lab also made a slew of other announcements yesterday. The company will be partnering with Anduril as part of its 20-launch contract with the War department to use its suborbital HASTE version of its Electron first stage for hypersonic testing. The deal involves three of those twenty launches.

The company also announced a partnership with Raytheon to “demonstrate advanced capabilities for the United States Space Force’s Space Based Interceptor program.” Rocket Lab also revealed it is acquiring the California robotic company Motiv Space Systems that has built equipment used on the Mars rover Perseverance.

Rocket Lab might not be as big as SpaceX, but it has unquestionably been as successful in its own way.

Louisiana state senator: Two unnamed aerospace companies are bidding for major land purchase

8:55 am

Pecan Island SpaceX facility?

In response to the story earlier this week that SpaceX might be acquiring a 200-plus square mile patch of land near Pecan Island on the southern coast of Louisiana, a state senator has now confirmed that two unnamed aerospace companies have been talking with landowners about a possible purchase.

State Sen. Bob Hensgens, R-Abbeville, said he knows of two companies — he did not reveal if it is Elon Musk-owned SpaceX or Jeff Bezos’ Blue Origin — that have reached out to landowners in coastal Vermilion and Cameron parishes about a possible acquisition. “I know both companies are trying to find property in southwest Louisiana,” Hensgens said. “I know from people in the parishes that the companies have made outreach in the area.”

If so, we might actually have a bidding war for this property. Note however that nothing has yet been confirmed, including the names of the companies involved. The article at the link however provides some background into the 136K acre plot owned by Exxon, and how it might now be for sale. It also reports that a number of legislators (not Hensgens) have signed non-disclosure agreements about the negotiations.

Testing new high speed rotors for the next generation of Mars helicopters

8:28 am

Engineers from JPL and the aerospace company AeroVironment have been testing a new set of high speed rotors that they hope to use on the next generation Mars helicopters, designed to increase their payload capacity by as much as 30%.

The rotors of Ingenuity — the first helicopter to fly on Mars — never spun faster than 2,700 rpm, because at faster speeds it would be approaching the speed of sound (on Mars), when unpredictable things could happen. Engineers are pushing those limits with these new rotors, in a chamber mimicking the thin Martian atmosphere.

The test engineers had taken the precaution of lining part of the chamber with sheet metal in case the blades broke apart during the supersonic experiment. From a control room a few yards away from the chamber, the team watched displays showing data and a view inside the chamber as the rpm climbed as high as 3,750. At that rate, the tips were traveling at Mach 0.98 [just under the Martian speed of sound]. Then the engineers activated a fan inside the chamber that pelted the rotors with headwinds. After each run, they increased in wind velocity for the next run.

The team pushed rotor tip speeds to Mach 1.08, boosting the Mars vehicle’s lift capability by 30%. This breakthrough allows future missions to support heavier scientific payloads, including advanced sensors and larger batteries for extended flight. Next the team tried their luck with the two-bladed SkyFall rotor. Because it is slightly longer than the three-bladed version, only 3,570 rpm was needed to achieve the same near-supersonic speed at the rotor tips prior to introducing the headwinds.

NASA administrator Jared Isaacman has said he wants to send a fleet of helicopters to Mars in 2028, on that first nuclear-powered mission. Whether or not that mission happens as he proposed, there is ample evidence scientists plan on sending more helicopters there in the next few years (see here, here, here). These tests lay the groundwork for those future missions.
