In May 2021 it was announced that ESA astronaut and Dragon Crew-4 mission specialist Samantha Cristoforetti would serve as Commander of International Space Station (ISS) Expedition 68a.
As part of normal vehicle scheduling, the Space Station flight programme was recently updated adjusting the upcoming crew rotation for Crew-4 and Crew-5, resulting in a shorter mission for Crew-4. ISS Expedition 68 will now take place after Samantha’s departure from the Station.
