NASA astronaut Mike Fincke has retired from the agency after a thirty-year career. A native of Emsworth, Pennsylvania, Fincke completed four space missions, logging 549 days in orbit and over 48 hours of time on spacewalks.
His departure follows an unusual medical event that occurred in January 2026. While serving aboard the International Space Station, Fincke experienced health complications that required the first medical evacuation in the station's twenty-five-year history. Following his return to Earth, he underwent testing and reported that he feels healthy, though the exact cause of the incident remains under investigation.
Fincke is now transitioning to a new role in academia. He will serve as a professor at the Massachusetts Institute of Technology, focusing on the Department of Aeronautics and Astronautics. He plans to develop courses and conduct research related to human spaceflight, sharing his experience in spacecraft development and mission operations with the next generation of engineers and astronauts.
Throughout his time at NASA, Fincke contributed significantly to multiple milestones, including work on the space shuttle Endeavour and various expedition missions. His career path represents a commitment to the practical challenges of space exploration and the technical requirements of keeping humans safe in orbit.
