Four astronauts will return from the International Space Station more than a month ahead of schedule after an unnamed crew member experienced a medical issue, reports BritPanorama.
NASA has not provided details about the nature of the problem, citing privacy concerns. The agency typically does not discuss specifics regarding the health matters of astronauts.
The affected crew member is in stable condition, NASA confirmed, and is not expected to receive special treatment during the return trip, said Dr. James Polk, NASA’s chief health and medical officer. Polk indicated that the astronaut would be best served by being evaluated on the ground.
“We have a very robust suite of medical hardware on board the International Space Station,” Polk noted during a Thursday news conference. “But we don’t have the complete amount of hardware that I would have in the emergency department, for example, to complete a workup of a patient.”
He added, “And in this particular incident, we would like to complete that workup, and the best way to do that is on the ground.”
The returning group includes American astronauts Mike Fincke and Zena Cardman, Japan Aerospace Exploration Agency astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov, forming NASA’s SpaceX Crew-11 team. This mission, part of the orbiting laboratory’s regular staffing rotation, was expected to conclude no earlier than next month. Typically, NASA would not bring a team back to Earth before another was in place.
NASA’s newly appointed administrator, Jared Isaacman — who has twice flown to orbit on private SpaceX missions — stated he made the call to bring the group of four astronauts home. He noted during a news briefing Thursday that the decision was informed by the upcoming launch of four crew members to the space station on NASA’s Crew-12 mission in the coming weeks, indicating that the agency is assessing ways to expedite that launch, initially slated for mid-February.
Isaacman confirmed that the Crew-11 team will depart the space station within “days.”
Delayed spacewalk
NASA revealed the astronaut’s medical concern on Wednesday when it announced the postponement of a planned spacewalk due to the undisclosed “medical concern.”
“These are the situations NASA and our partners train for and prepare to execute safely,” the agency commented in a statement.
When the Crew-11 astronauts return, only one NASA astronaut will remain on board the station: Chris Williams, who arrived in late November aboard a Russian Soyuz capsule as part of a ride-sharing agreement between the US and Russia.
Officials stated on Thursday that Williams is well prepared to handle any tasks that arise, and they are confident he will soon be joined by Crew-12 astronauts, restoring staffing to normal levels.
“This is one of the reasons why we fly mixed crews on Soyuz and US vehicles — because we want to ensure operators for both segments of the space station,” remarked Amit Kshatriya, NASA’s associate administrator.
The situation underscores the complexities of maintaining operations aboard the International Space Station, especially in light of unexpected medical events.
