2 of 4 Artemis II Astronauts Exit Active Corps, Leaving 1 Active

For space and defense operators, the headline isn't just two retirements—it's the fastest thinning of a flight-proven lunar crew in the Artemis era. NASA's April 2026 record-setting Artemis II flyby produced four astronauts with direct deep-space lunar experience; by September only Christina Koch still holds active status. That experience vacuum arrives as the agency prepares for its next lunar landing, making knowledge transfer and crew pipeline management the real mission-control challenge.

On Sept. 9, 2026, NASA confirmed that the two astronauts who commanded and piloted the Artemis II moonshot—Reid Wiseman and Victor Glover—will leave active astronaut status and move into newly designated emeritus roles. The announcement comes less than five months after the crew completed a lunar flyby in April 2026, a mission that set a new distance record for humanity and marked the first crewed return of humans to the lunar environment since Apollo. Wiseman and Glover's decision, made public by NASA Administrator Jared Isaacman, does not reflect a mission failure; rather, it signals a generational transition at the heart of the Artemis program.

9, 2026, NASA confirmed that the two astronauts who commanded and piloted the Artemis II moonshot—Reid Wiseman and Victor Glover—will leave active astronaut status and move into newly designated emeritus roles.

The Artemis II mission was not a landing. It was a shakedown flight of Orion beyond low Earth orbit, testing deep-space navigation, long-duration life support, and communication systems that will underpin the first Artemis moon landing. Its success gave NASA an operational foundation for Artemis III, but the program now faces an unusual situation: only one of the four Artemis II crew members remains on the active astronaut rolls. Canadian Space Agency astronaut Jeremy Hansen retired in July. With Wiseman and Glover joining him on the inactive side, mission specialist Christina Koch is the sole active member of that crew. This is a rapid exodus of flight-proven lunar experience, a scarce resource in a program that has not yet completed a landing.

Glover's move to California Polytechnic State University took effect Sept. 1, the same day he retired from the U.S. Navy. Cal Poly said he will help shape long-term strategies and inspire students in science and engineering, and Glover was explicit that his decision was rooted in family and personal mission. Three of his daughters are currently enrolled at Cal Poly, and the oldest has already graduated from there. Glover said he wants to keep talking about how faith and science work together, adding that he can still help NASA from the sidelines. Wiseman's future plans were not disclosed, but his status change will take effect later in September. Both men will serve as emeritus astronauts, donating their time to train and mentor NASA workers and share knowledge for future moon missions.

NASA is describing the emeritus arrangement as a new approach to capitalizing on expertise. Instead of waiting years for a command of a moon-landing mission, Glover chose to put spaceflight behind him and focus on young people and family. Wiseman's silence about next steps leaves the possibility of an undisclosed private-sector or government role, but for now both remain informal assets for NASA. The agency's willingness to retain them as no-cost or donated mentors suggests an awareness that losing two experienced lunar-flight astronauts at once is more than a routine retirement. It is a knowledge-management problem in a program where a handful of people have actually flown the next-generation spacecraft to the Moon.
