NASA delays spacewalk due to a 'medical concern' with a crew member

NASA has postponed an International Space Station spacewalk due to a medical concern with an unnamed crew member. This concern arose Wednesday afternoon on the orbital complex. The crew member is reported to be stable, and NASA is monitoring the situation closely. The agency stated that ending the Crew-11 mission early is also being considered. While a Japanese astronaut requested a private medical conference, such requests are routine. The spacewalk was planned to install equipment for a future solar array installation. NASA astronauts Mike Fincke and Zena Cardman were scheduled to perform the spacewalk. Crew-11 was expected to remain on the ISS until at least mid-February. Their replacement, Crew-12, is not scheduled to launch until February 15th at the earliest. NASA will provide further updates within the next 24 hours.
