NASA Ends ISS Mission Early Due to Astronaut’s Medical Issue
Louisville, KY – NASA has announced an early termination of the International Space Station (ISS) mission following a medical issue involving one of the crew members. The multinational crew of four—NASA’s Zena Cardman and Mike Fincke, Japan’s Kimiya Yui, and Russia’s Oleg Platonov—will return to Earth earlier than planned. The identity of the affected astronaut and the nature of the medical issue have not been disclosed, citing privacy concerns; however, NASA confirmed that the crew member is now stable.
Details of the Mission and Medical Concern
The crew arrived at the ISS in August 2025 via a SpaceX mission, with an initial plan for a six-month stay. A scheduled spacewalk intended to prepare for future solar panel installations was canceled due to the medical situation.

Current Status of the ISS Crew
Three other astronauts—NASA’s Chris Williams and Russia’s Sergei Mikaev and Sergei Kud-Sverchkov—remain aboard the ISS, with a return planned for the summer. NASA has long-term plans for SpaceX to deorbit the station around 2030 or 2031, with a controlled descent over the ocean.
