NASA carried out its first-ever medical evacuation from the International Space Station (ISS) when four astronauts returned to Earth earlier than planned.
The crew, consisting of Zena Cardman and Mike Fincke from the U.S., Kimiya Yui from Japan, and Oleg Platonov from Russia, undocked on Wednesday and aimed for a Thursday morning splashdown in the Pacific near San Diego.
The mission, originally scheduled to continue until late February, was cut short by over a month after one astronaut required medical attention. NASA did not disclose the identity of the astronaut or the nature of the health issue, citing privacy. Outgoing ISS commander Mike Fincke assured that the astronaut was “stable, safe and well cared for” and emphasised the importance of conducting full medical evaluations on Earth.
NASA cancelled a planned spacewalk on January 7 before announcing the early return. Officials clarified that the health problem was unrelated to spacewalk preparations or station operations. The return followed standard splashdown procedures, with medical experts on standby aboard the recovery ship.
The evacuation reduced the ISS crew size by more than half, leaving one U.S. and two Russian astronauts to continue their mission. NASA and SpaceX are now working to accelerate the launch of a replacement four-person crew from Florida, targeted for mid-February.
This marked the first medical evacuation in NASA’s 65 years of human spaceflight. Historical parallels include the 1985 case of Soviet cosmonaut Vladimir Vasyutin, who was forced to return early from Salyut 7 due to illness.
The decision was also the first major call by NASA’s new administrator, Jared Isaacman, who underscored that astronaut health and safety remain the agency’s highest priority.
