After a medical incident onboard the International Space Station (ISS) caused NASA to return the Crew-11 mission home early, the identity of the impacted crewmember has been revealed as NASA veteran astronaut Mike Fincke. Fincke, one of NASA's most experienced explorers, was the affected crew member who experienced a medical event that required immediate attention from his crewmates and led to the early return of the Crew-11 mission in January.

Why it matters

The early return of a crew from the ISS is a rare occurrence, with this being the first such incident in more than 25 years of continual occupancy on the orbiting laboratory. Fincke's medical situation highlights the challenges and risks astronauts face during long-duration spaceflight and the importance of having robust medical capabilities on the ISS.

The details

On Jan. 7, while aboard the ISS, Fincke experienced a medical event that required immediate attention from his crewmates. NASA developed a plan to bring the Crew-11 team home for further diagnostics that the station's onboard medical suite could not provide. On Jan. 14, the SpaceX Dragon Endeavour undocked from the ISS with all four members of Crew-11, including Fincke, and the capsule splashed down safely off the coast of San Diego on Jan. 15.

  • On Jan. 7, Fincke experienced a medical event while aboard the ISS.
  • On Jan. 8, NASA held a press conference to announce the early return of Crew-11 due to health concerns for an unidentified astronaut.
  • On Jan. 14, the SpaceX Dragon Endeavour undocked from the ISS with Crew-11.
