NASA astronaut Mike Fincke has retired after a thirty-year career with the agency. His departure follows the conclusion of his final mission, which ended early due to an undisclosed medical issue. Fincke is now moving on from his role at NASA following a distinguished career that saw him complete four separate missions.
During his time as an astronaut, Fincke recorded 549 days in space. This total places him fourth among all NASA astronauts for cumulative time spent in orbit. His experience includes serving as commander of the International Space Station during Expedition 18 and participating in the final flight of the space shuttle Endeavour. He was selected for the astronaut class in 1996 and served as a U.S. Air Force colonel and test pilot before joining the space agency.
His final mission involved the SpaceX Crew-11 flight earlier this year. A medical concern required an evacuation from the space station in January, marking the first time in history a mission returned early for health reasons. Fincke later confirmed he was the crew member involved, noting that the return allowed him to receive advanced medical imaging unavailable on the station.
While he is retiring from civil service, Fincke may still have a future in the private sector. The commercial space industry offers opportunities for former astronauts to return to orbit on private flights. He continues to support the next generation of engineers and explorers as he transitions away from his official duties at the agency.
