Here are some recent space-related stories of interest.

—ZME Science: “NASA Finally Figured Out What’s Up With Those “Mars Spiders”“

For years, satellites around Mars kept finding mysterious, spider-like geological structures. Mars spiders, scientifically known as araneiform terrain, are unique geological formations predominantly found in the southern hemisphere of Mars. They appear as branching, spider-like channels etched into the Martian surface, sometimes spanning over a kilometer in length. In 2024, NASA-led lab experiments pinned down the likeliest way these “spiders” form: seasonal CO₂ ice. Now, a 2026 follow-up showed that the soil beneath the ice can make or break the process, and that these structures could hold clues to Mars’ wet past.

—Earth.com News: “Why Do Astronauts Get Constipated in Space? Scientists Have a New Clue“

Astronauts have complained about constipation for as long as people have flown to space. Nobody could say exactly why. Researchers have long suspected that living without gravity changes how quickly food moves through the gut. Blood drawn from crew members on long stays aboard the International Space Station now points to an answer. Giorgia La Barbera, a joint first author of the study and an associate professor at the University of Copenhagen’s Department of Nutrition, Exercise and Sports, led the work with NASA. “We see changes in astronauts’ blood samples that indicate that the gut bacteria begin to ferment protein to a greater extent than usual within weeks after the astronauts arrive in space, and this change continues until they are back on Earth,” La Barbera said.

—CNN: “Chinese Rocket Carrying Satellite Explodes Seconds After Launch“

A Chinese rocket set to launch a satellite into orbit blew-up seconds after liftoff Monday, marking the relatively rare failure for a rocket considered a workhorse of Beijing’s space program. The Long March 7A rocket erupted into a massive fireball just 85 seconds after blasting off from the Wenchang Space Launch Site on the island of Hainan on Monday night, video showed. Unlike other successful launches, the incident appears to have been downplayed on China’s state media with scant mention of the explosion.

Pic of the Week: Psyche Spacecraft Approaching Mars

This week’s image is from NASA’s Psyche spacecraft, which was doing a flyby of Mars last month for a gravity assist on it way to asteroid Psyche in 2029. What you are seeing is a composite photo of the crescent of the planet as the Psyche spacecraft approached it. NASA shared the photo on July 17, 2026.

You can see much more related to this flyby at this NASA link.

“Early cost estimates are approximately $2.1 billion, and NASA will continue refining that figure through the acquisition process.”

-NASA statement quoted by Politico regarding the estimated cost to send a nuclear-powered spacecraft to Mars. These costs would only cover the recently disclosed Space Reactor-1 Freedom spacecraft, but not the payload of three helicopters called SkyFall. This comes at a time when NASA Administrator Jared Isaacman is meeting with Congress and stating the agency does not need any additional funds at this time. Congress has been good at restoring funds the White House has tried to cut, so maybe Mr. Isaacman feels lucky he has what he has and does not want to seem ungrateful. It appears Congress is making a trip to Mars possible and not the White House, no matter what the president might say on stage about the importance of America’s space program.

Space Quote: Dealing with Off-Planet Real Estate

“So, who should have the right to acquire property in space? My answer: those who have the financial means to get there, develop, and use the land. For instance, if SpaceX succeeds in reaching Mars and starts to build permanent settlements on the red planet, then the ownership of land should go to SpaceX first. Not of the entire planet, of course, but of a practicable area, for example the size of Singapore. The surface area of Mars is 200,000 times that of Singapore, so SpaceX would initially only own 0.0005 percent of Mars. That would be enough to develop multiple settlements, but not so many that others would no longer have a chance.”

-Statement by Rainer Zitelmann, a historian and sociologist, in his Reason magazine article titled “Why You Can’t Settle Mars or Colonize the Moon Without Real Property Rights.” You do not need to agree with his conclusion, but he discusses a timely topic. The Moon Agreement and Outer Space Treaty may need to be revisited now that the idea of permanent settlements on the Moon and Mars are not simply science fiction, as they were in the 1960s and 1970s when these provisions were agreed to (and not by all nations, keep in mind).

Volunteers Needed for Moon and Mars Simulation

Do you need to get away from the ordinary for something more stimulating (and possibly away from the constant political news)? How about going into isolation to assist NASA with future Moon and Mars missions?

NASA is looking for a few hardy souls to start a new virtual space mission in August 2027 at the Johnson Space Center in Houston, Texas. Volunteers must meet a variety of criteria, including being between 30 and 55 years old and willing to spend approximately 14-months on this mission, which includes 12 months in two different confined habitats and two months of pre- and- post-mission training and data collection. Oh yeah, you cannot have a history of sleepwalking or taking sleeping aids.

The volunteers will basically live and work in isolation and confinement while performing simulated missions related to interplanetary transit and planetary surface operations. This will also include simulated rover missions and spacewalks.

You can read all about it on this NASA info page, which includes an email address to ask more questions as well as an application form.

It’s not for everyone, but maybe it’s for you.

By the way, even if the White House cuts off the funding after you start the program, at least you will still be in Houston rather than half-way on your way to Mars with no way to get back.
