Four astronauts from the International Space Station (ISS) have returned to Earth nearly a month earlier than planned after one crew member developed a “serious” health problem, marking an unprecedented medical evacuation in the station’s history.
The astronauts safely splashed down in the Pacific Ocean off the coast of California, according to reports from the BBC. Since the ISS was first placed into orbit in 1998, this is the first instance in which astronauts have been brought back early specifically due to a medical emergency.
The Crew-11 mission was commanded by veteran NASA astronaut Mike Fincke. He was seen smiling as he exited the spacecraft, though he appeared slightly unsteady—an expected physical reaction after prolonged time in microgravity. He was followed by fellow NASA astronaut Zena Cardman, Japan’s Kimiya Yui, and Russian cosmonaut Oleg Platonov. Expressing her relief, Cardman said she was “very happy to be home.”
NASA Administrator Jared Isaacman told a press briefing that the ill astronaut is currently “doing well” and remains mentally alert. However, citing medical privacy policies, NASA declined to disclose the identity of the affected crew member or details of the illness. The agency had earlier hinted at a health issue last week when a scheduled spacewalk involving Fincke and Cardman was abruptly canceled.
The four astronauts had arrived at the ISS on August 1 and were originally expected to remain in orbit until mid-February. Their early departure has left the space station operating with a reduced, three-member “skeleton crew.” Russian cosmonaut Sergei Kud-Sverchkov has assumed command of the station, and his first directive after taking charge was for the remaining crew to share a group hug.
While rare, this is not the first time space missions have been cut short due to health concerns. Similar incidents occurred in 1985, involving Soviet cosmonaut Vladimir Vasyutin, and in 1987 with Alexander Laveikin.
Currently, the ISS is equipped with limited medical supplies and does not have a full-time physician on board. Experts say the incident highlights the growing need for enhanced medical capabilities in space, especially as human ambitions expand toward space tourism and long-duration missions to the Moon and Mars.
