NASA’s associate administrator will leave the agency at the end of the week as uncertainty continues about the timing and scope of potential job cuts.

In a statement late Feb. 19, NASA announced that Associate Administrator Jim Free will retire from the agency, effective Feb. 22. Free had been associate administrator, the top civil-service position in the agency, since the retirement of Bob Cabana at the end of 2023.

Free was previously associate administrator for exploration systems development, a position NASA created in 2021 when it split the former Human Exploration and Operations Mission Directorate into two directorates, one overseeing exploration programs and the other the International Space Station and related operations. Earlier in his 30-year NASA career, he was director of the Glenn Research Center in Cleveland.
