Mike Fincke to Leave NASA After 30 Years

Mike Fincke Retires From NASA After 30 Years

Fincke ranks fourth among NASA astronauts in accumulated time in space. Over his decades of service, he completed spacewalks totaling 48 hours and 37 minutes. Tributes from leadership highlighted his extensive contributions across multiple roles. Few people have had the opportunity to shape as many chapters of NASA’s history as Mike Fincke, said NASA Administrator Jared Isaacman in a NASA release, noting that Fincke served as a pilot, engineer, astronaut, and mentor.

Medical Incident and Early Return of Crew-11

Fincke’s departure comes months after a medical emergency aboard the International Space Station forced an early end to his most recent mission according to Mezha. Serving as pilot for NASA’s SpaceX Crew-11 mission—which launched in August 2025 and served during International Space Station Expedition 73 and Expedition 74—Fincke experienced an unexpected health issue that prompted an urgent response from CTVNews.

During the incident, Fincke was unable to speak for approximately 20 minutes. While he reported feeling no pain, the medical problem caused the space agency to cut the Crew-11 mission short and return to Earth in a middle-of-the-night splashdown near San Diego, California, on Jan. 15, 2026. Doctors confirmed he did not suffer a heart attack and was not choking. NASA Administrator Jared Isaacman referred to the event at the time as a serious medical condition. Fincke noted that the return allowed the crew to take advantage of advanced medical imaging not available on the space station, while NASA and medical researchers continue to investigate the cause.

Historic Flights and Ground Contributions

Fincke joined NASA’s 16th astronaut class in 1996. His flight experience spans multiple vehicle types and station eras:

• Soyuz TMA-4 (2004): Flew in support of Expedition 9 as a science officer and flight engineer, performing four spacewalks.
• Soyuz TMA-13 (2008): Served as commander of Expedition 18, preparing the station for six-person crews and completing two spacewalks.
• STS-134 (2011): Served as mission specialist and robotic arm operator on the final flight of space shuttle Endeavour, completing three spacewalks to deliver and install the Alpha Magnetic Spectrometer.
• SpaceX Crew-11 (2025–2026): Piloted the mission and served as an Expedition 73 flight engineer and Expedition 74 commander before an early medical return.

In addition to his time in orbit, Fincke supported station operations from the ground as a crew test support team member in Russia, a capsule communicator (capcom), and crew procedures team lead.

Legacy and Future Outlook

Colleagues praised Fincke’s dedication to human spaceflight and crew support. Vanessa Wyche, director of NASA’s Johnson Space Center in Houston, stated that his career reflects three decades of dedication to agency missions and mentoring. Scott Tingle, chief of the Astronaut Office at NASA Johnson, added that Fincke approached every assignment with experience, humility, and an unwavering focus on the mission.

Reflecting on his departure, Fincke expressed gratitude for his time with the agency and his anticipation for the future of space exploration. After exactly 30 years, I am departing NASA, but I remain deeply committed to the work of exploration, Fincke said in a Spectrum News 13 report. Neither Fincke nor NASA has publicly announced specific details regarding his professional plans following his retirement.
