Veteran NASA astronaut Michael Fincke revealed Wednesday he was the crew member who experienced a medical issue during a recent mission to the International Space Station, prompting an unprecedented early return to Earth for him and three colleagues.
The unexpected evacuation of Crew-11 in mid-January marked the first time NASA had curtailed an ISS mission for health reasons, a decision made after Fincke, 58, experienced a medical event while aboard the orbiting laboratory. NASA did not initially disclose the astronaut’s identity or the nature of the problem.
“On Jan. 7, while aboard the International Space Station, I experienced a medical event that required immediate attention from my incredible crewmates,” Fincke said in a statement released by NASA. “Thanks to their quick response and the guidance of our NASA flight surgeons, my status quickly stabilized.”
Fincke, a retired United States Air Force colonel and veteran of multiple spaceflights, explained that NASA determined the crew’s return was necessary to access “advanced medical imaging not available on the space station.” The ISS is equipped with medical supplies, but lacks the comprehensive diagnostic capabilities of a terrestrial hospital.
The crew, which included NASA astronaut Zena Cardman, Kimiya Yui of the Japan Aerospace Exploration Agency and cosmonaut Oleg Platonov of the Russian space agency Roscosmos, landed in the Pacific Ocean off the coast of San Diego, California, on January 15, 2026. Their departure left a reduced crew of three to maintain operations on the ISS.
While Fincke did not detail his specific medical condition, he stated he is “doing very well and continuing standard post-flight reconditioning at NASA’s Johnson Space Center in Houston.” He has logged 548 days, 8 hours and 8 minutes in space across multiple missions, including long-duration stays on the International Space Station as a flight engineer and commander, as well as a Space Shuttle mission.
Fincke is uniquely qualified to operate a variety of spacecraft, having been certified as a pilot for both Boeing Starliner and SpaceX Crew Dragon, as well as a co-pilot/flight engineer on the Soyuz and a mission specialist on the Space Shuttle. He has also completed nine spacewalks, totaling 48 hours and 37 minutes of extravehicular activity, including six in a Russian Orlan spacesuit.
NASA has not released further details regarding the medical event, and the agency has not commented on any potential impact to future ISS missions or astronaut health protocols. The investigation into the incident remains ongoing.
