The latest podcast episode of the Planetary Society’s Planetary radio had an informative discussion about space stations, including why we need them and who should be financing them. The episode, What’s Going on with Commercial Space Stations, is a conversation between Casey Dreier, Chief of Space Policy for The Planetary Society, and Clayton Swope, Deputy Director of the Aerospace Security Project and Senior Fellow for The Center for Strategic and International Studies (CSIS).

Mr. Swope wrote an story last month for CSIS titled “NASA Changes Course on Commercial Space Stations.” In it, he notes that NASA’s recent change to its program for commercial space stations was due to greater skepticism about the private sector’s ability to make a business case for a space station and then properly construct one in a timely fashion. This is the crux of his discussion with Casey Dreier, which is fun to follow.

Should the federal government continue to take the lead on both the financing and construction of manned space stations to replace the International Space Station (ISS) once it is retired? And why do we even need another manned space station? Does it serve a commercial purpose that cannot be replicated with robots? Or is it more akin to our nation’s support and participation in the Olympics, where we can show American prowess while hopefully taking sports to a new level?

The conversation covers a fair amount of ground, while the Planetary Radio website offers a variety of background links as well as some useful information on the proposed commercial space stations, including:

  • Axiom Station,
  • Orbital Reef,
  • Starlab,
  • Cygnus spacecraft captured by Canadarm2, and
  • Sierra Space LIFE habitat.

NASA and the private sector will need to find a way to make this Earth-orbiting commercial space station a viable option before the ISS is little more than a shooting star. NASA has already killed the Moon’s space station earlier this year (aka Gateway), demonstrating that it is willing to move quickly and break things.

A Martian Rover on the Moon?

It seems NASA is looking for some shortcuts to get back on the Moon, including repurposing an earlier rover designed for Mars. The rover in question is called the Polar Rover for Observation, Mapping and In-Situ Exploration, or simply PROMISE. It is the test model for the Perseverance and Curiosity rovers currently exploring Mars.

One of the advantages of the Mars rover is its power source. Instead of relying on solar panels, the rover is powered by a nuclear battery. This will give it greater range on the Moon’s surface without having to wait for lunar daylight. Another advantage is that it is proven technology, as the two Martian rovers have demonstrated for years.

It sounds like a smart way to take something off the shelf, but one can only wonder why this is only being considered now after NASA spent more than $450 million on the Volatiles Investigating Polar Exploration Rover (VIPER) project. Was a nuclear battery ever considered for VIPER? These Martian rovers have been around for quite some time, and a nuclear reactor has been discussed as part of the Moon Base itself, so this is not a new idea.

Given this change in plans, one might expect that the contract with Blue Origin to bring the VIPER to the Moon in 2027 is no longer needed. Maybe VIPER will put on a shelf for years like PROMISE until someone comes up with a new purpose for it.

Stay tuned.

Space Stories: New Lunar Lander on Display, Caltech Approves a Radio Telescope, and Missing Galactic Dark Matter

Here are some recent space-related stories.

—Satnews: “Pittsburgh’s Moonshot: Astrobotic Unveils Griffin-1 Lander Ahead of Historic NASA ‘Moon Base II’ Mission“

Emerging as a powerful symbol of regional industrial pride and the rapid privatization of deep-space logistics, Astrobotic Technology has officially unveiled its massive Griffin-1 lunar lander. The vehicle, which has been formally designated by NASA as the primary infrastructure vehicle for the Moon Base II task order under the Commercial Lunar Payload Services (CLPS) program, represents a critical stepping stone toward establishing a permanent, self-sustaining human presence on the lunar surface. Unlike smaller, first-generation commercial scouts, the Griffin platform is an “infrastructure-class” logistics vehicle engineered to transport heavy industrial cargo. Boasting a massive 625 to 650-kilogram payload capacity, the stout aluminum isogrid lander is designed to ferry bulky machinery, scientific sensor arrays, and alternative energy installations directly to the rugged, hazardous terrain of the lunar south pole.

—Newser: “Giant Nevada Project Could Transform Astronomy“

Caltech has approved the final design for the Deep Synoptic Array, a $200 million radio telescope project that will blanket a chunk of desert with 1,650 dishes over roughly 120 square miles—an array designed to scan the sky about 100 times faster than any existing telescope. Backed in part by Schmidt Sciences, the philanthropic effort of former Google CEO Eric Schmidt and his wife Wendy, the project is slated to be finished by 2029 and will be powered by a supercomputer that turns torrents of radio signals into sharp images on the fly.

—W.M. Keck Observatory: “Astronomers Discover Third Galaxy Without Dark Matter“

Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island, have discovered the third known galaxy apparently lacking dark matter, part of a strange linear structure that may have formed during a violent collision between galaxies. The discovery strengthens evidence for a rare and previously unseen process in which ordinary matter becomes separated from dark matter, offering astronomers a powerful new way to study one of the universe’s greatest mysteries.

Artemis III Has a Crew

Earlier today NASA announced its new four-member crew for the next set of Artemis tests. The two week long Artemis III mission will test spacecraft in low Earth orbit in preparation for Artemis IV, which will entail an actual crewed mission to the surface of the Moon.

The new crew are three NASA astronauts and one European Space Agency (ESA) astronaut from Italy. NASA has a full profile of each crew member, but here are the basics:

NASA may have a crew, but does it have any partners that are really ready for a lunar landing?

To date, the only fully operational spacecraft is the Orion capsule, which will be sent aloft via the Space Launch System. Both SpaceX and Blue Origin plan to send up demonstration lunar landers that will not contain all of the necessary components for humans preparing for a Moon landing. This sounds a little dangerous given that the real reason for Artemis III is a dry-run in space. It sounds more like a dry-run for a dry-run, but NASA may not have time to complete a true test.

In additon to lunar lander delays, SpaceX is busy trying to make a fortune with its IPO, while Blue Origin is still licking its wounds after the recent explosion at Cape Canaveral.

These four astronauts may be the best news out of NASA for some time to come, so it may be best to raise a toast to the four of them and then simply hope for the best.

Space Stories: ESA & China Are Smiling, Blue Origin Beats SpaceX to the Moon, and JWST Analyzes Exoplanet Atmosphere

Here are some recent space-related stories.

—European Space Agency: “Smile Lifts Off on Quest to Reveal Earth’s Invisible Shield Against the Solar Wind“

The Smile spacecraft lifted off on a Vega-C rocket from Europe’s Spaceport in French Guiana at 04:52 BST / 05:52 CEST (00:52 local time) on 19 May 2026. The launch marks the beginning of an ambitious mission to better understand solar storms, geomagnetic storms, and the science of space weather…Smile is a collaboration between the European Space Agency (ESA) and the Chinese Academy of Sciences (CAS). It will reveal how Earth responds to the streams of particles and bursts of radiation from the Sun, using an X-ray camera to make the world’s first X-ray observations of Earth’s magnetic shield, and an ultraviolet camera to watch the resulting northern lights non-stop for 45 hours at a time.

—The Guardian: “Nasa Selects Jeff Bezos’s Blue Origin for First of Three Uncrewed Lunar Missions“

Nasa announced on Tuesday ambitious plans for three uncrewed lunar missions this year to kickstart construction of a $20bn moon base, and said it had chosen the Amazon founder Jeff Bezos’s Blue Origin, ahead of Elon Musk’s SpaceX, to conduct the first...[NASA’s Administrator] said the three missions planned for 2026 would be followed by “more than a dozen” more in the coming years to test systems and equipment. He said the highly successful Artemis II mission last month that sent four astronauts around the moon for the first time since 1972 had been both a catalyst and incentive to advance the moon base plan.

—Astrobiology: “Astronomers Observe Exoplanet Atmospheres With New Cloud-detecting Method“

Every morning, clouds roll in, and by evening, they have cleared off. This sounds like a weather forecast for a coastal city here on Earth — but it’s for WASP-94A b, a well-studied gas giant orbiting a star located nearly 700 light-years away. A new study published in the journal Science documents the first detection of repeating cloud cycles on a hot Jupiter exoplanet. The first author of the study is Sagnick Mukherjee, a 51 Pegasi b postdoctoral fellow at Arizona State University’s School of Earth and Space Exploration. Mukherjee is part of a research team that analyzed data from the James Webb Space Telescope targeting WASP-94 A b, a gas giant in the constellation Microscopium. The team discovered that the planet’s morning side is blanketed in clouds of magnesium silicate, the same mineral found in common rocks, while its evening side is under clear skies.
