SpaceX postponed a mission to send the next crew to the International Space Station (ISS) and return astronauts Barry Wilmore and Sunita Williams due to a hydraulic issue with the launch tower, not the spacecraft.

The mission was rescheduled for Thursday or Friday evening.

Wilmore and Williams, who have been on the ISS since June 2024 after conducting Boeing’s Starliner crewed test flight, were initially supposed to return earlier but stayed until Crew-10’s launch.

The pair assisted with research and responsibilities on the ISS, ABC News has reported.

SpaceX plans to livestream the mission, part of NASA’s Commercial Crew Program.
