NASA astronaut Christina Koch will transition to management astronaut status and step down from flight eligibility on November 1, to become the agency’s acting deputy chief engineer at headquarters, succeeding the retiring Katherine Van Hooser.
Christina Koch Steps Down From Flight Status for Agency Leadership Role
Christina Koch is trading the command module for engineering headquarters. Beginning Sunday, November 1, the veteran astronaut and engineer will serve as NASA’s acting deputy chief engineer, according to an agency announcement. The appointment permanently alters her career path, classifying her as a management astronaut and making her ineligible for future spaceflight assignments.
The transition follows the retirement of Katherine Van Hooser, who concludes more than 35 years of distinguished service to the agency on Wednesday, October 21.

Administrator Isaacman noted that Koch brings a rare combination of operational experience and technical expertise to the post. Her background as a professional engineer is noted by the agency. Amit Kshatriya, NASA associate administrator and chief engineer, praised Van Hooser for guiding the agency through critical milestones and expressed confidence in Koch’s ability to maintain that standard of excellence.
From Record-Breaking Spaceflight to Artemis Mission Readiness
Koch most recently served as a mission specialist on NASA’s Artemis II mission in April, helping carry out the first crewed flight around the Moon in more than 50 years. Before her lunar flyby assignment, she spent 328 consecutive days aboard the International Space Station, setting the record for the longest single spaceflight by a woman and participating in the historic first all-female spacewalks.

That deep operational background shaped her role on Artemis II. In her new oversight role at headquarters, she will direct the engineering workforce across multiple programs, ensuring the technical foundations remain strong for upcoming endeavors including the Artemis III lunar landing, long-term lunar base development, space nuclear power initiatives, and eventual Martian transit capabilities.
A Legacy of Propulsion Engineering and Flight Operations
Koch’s own trajectory at the agency began long before her orbital records. She started her career as an electrical engineer at the Goddard Space Flight Center in Greenbelt, Maryland, developing scientific instruments for space missions. Before her selection into the astronaut corps in 2013, her résumé included scientific field engineering stints in Antarctica and the Arctic, followed by leadership positions within the Astronaut Office and the Johnson Space Center in Houston.
