Stuck Astronaut Butch Wilmore Retires From NASA Months After Prolonged Spaceflight

One of NASA's two previously stuck astronauts has retired from the space agency, less than five months after his unexpectedly long spaceflight came to an end.

NASA announced Butch Wilmore's departure on Wednesday.

After 25 years at @NASA, flying in four different spacecraft, accumulating 464 days in space, astronaut and test pilot Butch Wilmore has retired from NASA.

Congratulations on an extraordinary career. Thank you for your service, your ingenuity, and the legacy you leave behind.… pic.twitter.com/NISrm2QQgT

Wilmore and Suni Williams launched last summer as test pilots on Boeing's first astronaut flight. What should have been a weeklong trip to the International Space Station turned into a stay of more than nine months because of Boeing's malfunctioning Starliner. Starliner came back empty, and Wilmore and Williams returned to Earth in March with SpaceX.

Wilmore, 62, had already retired from the Navy. Williams, 59, also a retired Navy captain, is still with NASA. She joined Second Lady Usha Vance at Johnson Space Center in Houston earlier this week, taking part in a summer reading challenge for schoolchildren.

Selected as an astronaut in 2000, Wilmore logged 464 days in orbit over three missions. His final spaceflight made up nearly two-thirds of that total: 286 days.

"Throughout his career, Butch has exemplified the technical excellence of what is required of an astronaut," NASA's chief astronaut Joe Acaba said in a statement. "As he steps into this new chapter, that same dedication will no doubt continue to show in whatever he decides to do next."
