“A spacewalk planned for Thursday outside the International Space Station was called off late Wednesday because of a ‘medical concern’ with an unidentified crew member, NASA said in a statement. An update shortly before midnight said the agency was exploring ‘all options, including the possibility of an earlier end to Crew 11’s mission.’ … Going into the new year, the crew expected to remain in space until their replacements arrive in mid-February. Crew 11’s return to Earth is expected around Feb. 20. That’s still the official plan.” (01/08/26)
