NASA has decided to postpone the launch of the Crew-10 mission, which will transport four astronauts to the orbital station, from February to March 2025. Wilmore, Williams, and the two other crew members of the ISS will have to wait for the arrival of the new expedition team before they can return home on the Dragon spacecraft, which is currently docked at the station.
This "provides NASA and SpaceX teams with time to complete the preparations for the new Dragon spacecraft for the mission," states NASA's announcement.
