NASA Scraps Spacewalk Amid ISS Medical Concern
NASA postponed its first spacewalk of 2026 and said it is considering an early end to the current International Space Station crew rotation after an unspecified medical issue involving one crew member.
In a statement posted late Wednesday, NASA said it "is postponing the Thursday, Jan. 8, spacewalk outside the International Space Station. The agency is monitoring a medical concern with a crew member that arose on Wednesday afternoon aboard the orbital complex."
NASA added that it would not identify the astronaut or provide details, saying: "Due to medical privacy, it is not appropriate for NASA to share more details about the crew member. The situation is stable."
The agency said it is reviewing options, including ending the mission early, and indicated more information would be forthcoming.
