NASA has announced the potential early return of the Crew-11 mission from the International Space Station (ISS) due to a medical issue affecting one astronaut. The agency has postponed an upcoming spacewalk that was scheduled for January 8, which involved American astronauts Mike Fincke and Zena Cardman. While the specific crew member affected has not been named, NASA confirms their condition is stable.

The Crew-11 mission, which arrived at the ISS on August 2, 2025, includes Fincke, Cardman, and Japan Aerospace Exploration Agency astronaut Kimiya Yui. This unexpected rotation change is highly unusual and may impact the schedule for the upcoming Crew-12 launch, planned for mid-February. Currently, the ISS is also staffed by NASA astronaut Christopher Williams and Russian cosmonauts Sergey Kud-Sverchkov and Sergey Mikayev.

This situation highlights the complex logistics of maintaining continuous human presence in orbit and underscores the rigorous medical protocols in place for long-duration spaceflight.
