Four astronauts circled the Moon earlier this year, more than 50 years after the final lunar landing, but only one of them will remain an astronaut going forward. Canadian astronaut Jeremy Hansen (age 50), who served as mission specialist on the Moon mission, retired from his position with the Canadian Space Agency in July. And now we learn that NASA astronauts Reid Wiseman (age 50), who served as commander on the mission, and Victor Glover (age 50), who served as pilot, have also announced their plans to depart as well.

Either there is something in the water, or age 50 is a good time to step away from an astronaut gig.

Hansen said he was pursuing new professional opportunities, Glover said he has a new job at California Polytechnic State University, and Wiseman provided no additional information. However, both Glover and Wiseman will transition to emeritus status. It is not clear if that is just a thank you role that gives them a discount at the agency cafe, or will entail some real duties.

NASA defines the emeritus role this way:

In an emeritus role, individuals with a high degree of technical and professional knowledge can continue to support the agency by donating their time to train and mentor the current workforce. This allows the agency to maintain access to top talent in a specialized consultant role, while simultaneously providing the individual with the flexibility to pursue other opportunities.

That leaves one Artemis II astronaut still standing – Christina Koch (age 47).

Back in August, all four were awarded the Congressional Space Medal of Honor at Houston’s Johnson Space Center. It is just unfortunate the they are leaving at a time that a lunar program is starting to grow.

All we can do is wish them well in their post-astronaut careers. They have plenty of stories that will hopefully encourage a new generation of astronauts.

Note: I want to make it clear that NASA astronauts do not need to retire at a certain age. For example, NASA astronaut Don Pettit was heading back to Earth from his latest space mission on his 70th birthday.

Space Stories: A New Lunar Spacesuit, a Map of the Cosmos, and Modeling Planetary Systems

Here are some recent space-related stories of interest.

—Ars Technica: “Wary of Artemis IV Timeline, NASA is Changing Lunar Spacesuit Design”

NASA has decided to use a simpler spacesuit for its initial missions to the lunar surface, Ars has learned. The agency announced the decision during an internal meeting this week as it seeks to accelerate its program to land humans at the south pole of the Moon as early as 2028. At the direction of Artemis Program Manager Jeremy Parsons, NASA will work with Axiom Space to develop a “Sortie Suit” variant of the planned spacesuit for the lunar surface. Sources said the Sortie Suit will be used for the initial landing missions flown on landers developed both by SpaceX and Blue Origin. Among the goals of the initiative are to lower the mass of the spacesuit, reduce its complexity, and simplify interfaces between the spacesuits and lunar landers.

—Wired: “Astronomers Have Completed the Largest Map of Space. Yes, You Can Play With It.“

The driving force behind our universe’s accelerated expansion remains one of the greatest mysteries in astronomy. While this force, which scientists refer to as dark energy, pervades our universe, we know almost nothing about it. Located on a remote mountain in Arizona’s Sonoran Desert, the Dark Energy Spectroscopic Instrument (DESI) has spent the past five years mapping the cosmos with the goal of unraveling this mystery. The result is the largest three-dimensional map of the universe ever created. And now—with the release of the latest version of the DESI Legacy Imaging Surveys, a free online tool for exploring the vast imaging data—you too can poke around the universe.

—Phys,org: “New Solar System Models Show Earth is No Fluke“

Over the past three decades, computer models of planetary system formation have gone from fairly crude representations to sophisticated simulations using thousands of different starting points. A paper presented at the Origins 2026 conference in Paris details innovative simulations of how our solar system might have formed without making assumptions about the planetary architecture with which we are so familiar. In his paper, Nader Haghighipour, a planetary scientist at the University of Hawaii in Manoa, argued that his models, unlike previous models, incorporate many completely random starting points and, in turn, let physics drive the models’ ultimate evolution. As a result, these new models are much more complete and allow physics to dictate their outcomes.

“[Mars Telecommunications Orbiter] is the backbone of America’s Mars exploration program for the next decade and beyond and will provide the reliable communications capacity that will keep future robotic and human missions connected to each other and to Earth…This awarded contract is a testament to the Blue Origin team that has been building Blue Ring with exactly this kind of mission in mind. We’re ready, and so is the hardware.”

–Statement by Tory Bruno, president, Blue National Security at Blue Origin, discussing the role of the planned MTO mission for NASA. The MTO is a firm-fixed-price contract with a maximum potential value of approximately $700 million. Part of the Moon to Mars Artemis program, the MTO is expected to be delivered to NASA no later than December 31, 2028.

Chinese Spying: The Moon Race Just Got Ugly

The US Department of Justice (DOJ) has reported that the Chinese have been hacking into US government agencies since as early as 2018. One of the targets of the Chinese hacker group, known as QTFY, was NASA.

A DOJ press release from earlier today, titled Justice Department and FBI Seize Platforms Operated and Used by China State-Sponsored Hackers to Target U.S. Critical Infrastructure, stated:

Among the victims of QTFY computer intrusion activity are the National Aeronautics and Space Administration, Federal Reserve, Department of Energy, Department of Justice, Department of Health and Human Services, National Institutes of Health, and the U.S. Senate.

At this time, the nature of what was taken from NASA and other government agencies was not provided. However, given the importance of the Artemis mission for both national and commercial purposes, it is not hard to believe that Artemis information was part of the hack.

It may be to NASA’s advantage that it has been operating by the seat of its pants for more than a year now. There was no Artemis strategy to steal. In addition, much of NASA’s work is in the hands of the private sector, so that extra layer of protection may have helped.

It is worth noting that many federal agencies were spending last year fighting off internal hackers from the US Department of Government Efficiency (DOGE), which did great damage across the federal government.

The Chinese efforts have been detected and ended. I am not sure you can say the same thing about DOGE.

Update: NASA Administrator Jared Isaacman has reported that the Chinese hackers were unable to access NASA data.

Space Stories: A Far Side Satellite, Congressional Space Medals, and the Scrubbing of a Chinese Moon Mission

Here are some recent space-related stories of interest.

—Universe Today: “The CosmoCube Satellite Will Listen to the Early Universe From the Far Side of the Moon”

Multiple space agencies are gearing up to send missions to the Moon in the near future…For one thing, the far side of the Moon is “radio-quiet,” meaning that it is not subject to radio interference from terrestrial sources. This makes the environment the perfect place to conduct radio astronomy research, including the new CosmoCube satellite currently under development at the University of Cambridge. Using the Moon as a natural shield, this satellite will listen for faint whispers (the 21-centimeter line) emitted by hydrogen atoms that existed between the Big Bang and the period known as “Cosmic Dawn.”

—Science Daily: “Trump to Award Congressional Space Medal of Honor to Artemis II Astronauts“

President Donald J. Trump will present the Congressional Space Medal of Honor to each member of NASA’s Artemis II crew during a ceremony at Johnson Space Center in Houston. The event is scheduled for 11 a.m. EDT on Friday, Aug. 28. The medal is one of the highest honors associated with human spaceflight in the United States. It recognizes astronauts whose achievements have made an exceptional contribution to the nation’s space program.

—Scientific American: “China Delays Ambitious Chang’e 7 Moon Mission until 2027“

China’s lunar ambitions took a hit after the country called off the launch of a spacecraft that it has aimed to make the first to ever land on the moon’s south pole. Chang’e 7 was supposed to launch onboard a Long March 5 rocket on August 24, but the launch was scrubbed on Sunday evening, China’s Manned Space Agency (CMSA) said in a statement. Poor weather conditions linked to Typhoon Narra were likely a factor. As a result, the mission will be put on ice until at least 2027.

Note: No podcast will be available this week. The program was finicky and difficult to edit.
