NASA has ordered an early return for its SpaceX Crew-11 team following an undisclosed health issue affecting one of the astronauts aboard the International Space Station.
The Medical Decision
The space agency announced the decision Thursday, Jan. 8, after determining the crew member needed evaluation beyond what the ISS medical bay can provide. The station carries “a very robust suite of medical hardware,” according to Dr. James Polk, NASA’s chief health and medical officer, but lacks equipment “to complete a workup of a patient.”
The affected astronaut’s condition remains stable, and officials stressed the situation poses no danger to the station’s operations.

Crew and Timeline
The Crew-11 team includes:
- Zena Cardman (NASA)
- Mike Fincke (NASA)
- Kimiya Yui (JAXA)
- Oleg Platonov (Roscosmos)
Originally scheduled to return in mid-February, the crew will now come home “earlier than originally planned” though NASA has not yet set a firm splashdown date.
Agency Response
NASA Administrator Jared Isaacman emphasized the decision prioritizes crew welfare:
> “It’s in the best interests of our astronauts to return Crew-11 ahead of their planned departure.”
The agency is coordinating with SpaceX and international partners to both bring Crew-11 home and accelerate preparations for the subsequent Crew-12 mission.
Key Takeaways
- First ISS mission ever shortened for medical reasons
- Astronaut’s specific condition withheld for privacy
- Crew has completed five months of scientific research
- NASA expects return-date decision within days
The shortened mission underscores the challenges of providing comprehensive medical care 250 miles above Earth.
