Four astronauts evacuated from the International Space Station (ISS) have safely returned to Earth after their mission was cut short by about a month due to a serious medical issue affecting one of the crew members.
The astronauts splashed down off the coast of California, marking the first medically driven evacuation from the ISS since the orbital laboratory began operations in 1998. Crew commander and veteran Nasa astronaut Mike Fincke was the first to exit the spacecraft, smiling as he was assisted onto a gurney in line with standard post-landing procedures. He was followed by Nasa astronaut Zena Cardman, Japan Aerospace Exploration Agency (JAXA) astronaut Kimiya Yui, and Russian cosmonaut Oleg Platonov, all of whom appeared in good spirits. “It’s so good to be home,” Cardman said shortly after landing.
The crew, known as Crew-11, will undergo routine medical evaluations before being flown back to land. Addressing reporters after the splashdown, Nasa Administrator Jared Isaacman said the affected astronaut was “fine right now” and in “good spirits.” In line with Nasa’s long-standing policy on medical privacy, the agency is not expected to disclose the identity of the crew member or details of the health condition.
Operational control of the ISS has since been transferred to Russian cosmonaut Sergey Kud-Sverchkov, who remains aboard with two other crew members. Crew-11 arrived at the station on August 1 with plans to complete a standard six-and-a-half-month mission, scheduled to end in mid-February. However, concerns emerged last week after a planned spacewalk involving Fincke and Cardman was abruptly cancelled. Hours later, Nasa confirmed that a crew member had fallen ill, prompting the decision to end the mission early.
Describing the handover as emotional, Fincke said the early departure was “bittersweet,” while reassuring the public in a social media post that all crew members were “stable, safe, and well cared for.”
Orbiting Earth at an altitude of approximately 250 miles, the ISS travels at around 17,500 miles per hour and completes 16 orbits daily. Operated by five international space agencies, the station supports extensive scientific research on space, including studies on how microgravity affects humans, animals, and plants. While astronauts receive medical training and the ISS carries limited medical equipment, there is no doctor permanently stationed on board.
The evacuation has been widely viewed as a critical test of Nasa’s medical response protocols in space. By most assessments, the procedures functioned as intended, though experts note the incident may raise broader questions about preparedness for more severe medical emergencies during long-duration missions.
Following Crew-11’s return, the ISS is now operating with a reduced crew of three Nasa astronaut Chris Williams and Russian cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev until the arrival of a new four-person crew in February. Despite the reduced staffing, Kud-Sverchkov expressed confidence in maintaining operations, pledging that the remaining crew would continue scientific and maintenance work as planned.
The incident is unprecedented in the ISS’s 26-year history of continuous human occupation. Historically, only two space missions have ended early due to health issues: a 1985 Soviet mission to the Salyut 7 station and a 1987 mission aboard the Mir space station.
As human spaceflight expands to include tourism and future missions to the Moon and Mars, experts increasingly argue that medical professionals may need to be included on longer and more complex space missions to address emerging health risks.
