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.

NASA Helps with Mining the Moon

While everyone was staring up at the dark Moon covering the bright sun during today’s eclipse, NASA was busy chatting about new ways to view the Moon. The image above is one of many that can be created using NASA data to assist commercial companies trying to understand the lunar terrain while looking for useful minerals.

The accompanying NASA story includes comments from multiple commercial companies eyeing the Moon’s resources.

Blair DeWitt, CEO of Lunar Station, stated:

We can find sites for landing pads, for cultivating the best paths for roving, and inform our clients about communications. If you can’t see Earth at a given location like in the polar regions or the far side of the Moon, you have to come up with a relay strategy…We can do this in part thanks to NASA data.

We can assume the Chinese are doing the same for their own commercial sector, though NASA has more data going back decades. Even so, China already has rocks from the far side of the Moon, which is a feat that not even NASA achieved. And not to be outdone, just last week China released its own comprehensive geological map of the Moon.

As with everything else pertaining to the Moon, the race is on.

Pic of the Week: Chinese Probe Captures Earth’s Quasi-Moon

This week’s image comes from a Chinese probe called Tianwen-2. It shows the spinning asteroid 2016 HO3, or Kamo‘oalewa, which is labeled by some of a “quasi-moon” of Earth until it decides to move on. Unlike the actual Moon, this asteroid is simply joining the Earth as it circles the Sun. The asteroid is about the size of a school bus.

The Chinese probe, launched from China in May 2025, is believed to have started its orbit of asteroid Kamo‘oalewa on June 6th of this year. It is now believed to be a rubble-pile asteroid, meaning it is basically loose material rather than a solid object. Even so, the Chinese probe may try to grab a sample to be returned to Earth in November 2027.

The source of the asteroid is still being debated, with some believing it is a piece of the Moon dislodged by an incoming asteroid while others believe it comes from the main asteroid belt.

In a paper released last year, scientists were leaning towards its origin being the main asteroid belt, noting:

Quantitative estimates show that population models of [Near Earth Asteroids] based on the migration of objects from the main belt are capable of accounting for Kamo‘oalewa-like objects. This relative contribution supports the hypothesis that (469219) Kamo‘oalewa originated from the main belt, which will be further investigated by future observations and in situ exploration of the Tianwen-2 spacecraft.

How long will it remain Earth’s partner? Back in 2021, Renu Malhotra, a UArizona planetary sciences professor, stated:

It will not remain in this particular orbit for very long, only about 300 years in the future, and we estimate that it arrived in this orbit about 500 years ago.

China Also Has a Reusable Rocket

Earlier today China successfully recovered the first stage of its Long March 10b rocket (as shown above and also in a CNN video). The rocket was launched from Hainan island in southern China. 

Up to this point, only SpaceX and Blue Origin have been able to accomplish this feat. This means China is joining the U.S. in terms of reusable rockets at a time when it is also making strides in the race to the Moon.

The rocket test was also successful in putting a satellite into low-Earth orbit.

The Long March 10b rockets was built by a state-owned company and is an essential part of China’s plans to send a crew to China. It is also said to be part of China’s plans to put internet satellites into orbit, similar to SpaceX’s Starlink.

One interesting part of the recovery was the use of a large net on the platform. Chen Muye from the China Aerospace Science and Technology Corporation (the state-owned company) stated:

Net-based recovery simplifies the onboard structure, reduces weight and boosts payload capacity.

Maybe the US commercial space sector has a few things to learn from the Chinese.

Space Quote: The Taikonauts Are Coming!

“Well, I would just say, first, it’s not arguably like there- we are very much in a space race right now, and the Chinese are moving at incredible speeds, and they are certainly capable of doing what the Soviets were not during the- the first space race. The Chinese will land their taikonauts on the moon. There’s no question. The question is, will the United States return before them, and will we do so in a different way this time, when we build a base, establish that enduring presence? I think the answer is yes.“

-Statement by NASA Administrator Jared Isaacman on CBS’s Face the Nation this past Sunday. The interview addresses other issues in addition to the Artemis mission to the Moon, including efforts to save the Swift space telescope as well as the status of Blue Origin’s efforts to recover from the recent explosion of its New Glenn rocket.
