SpaceX scrubbed the launch of a relief crew on Wednesday night, delaying the handoff for NASA astronauts who have been awaiting a return trip to Earth.

SpaceX aims to launch Crew-10 on Friday. The crew-swap mission will enable NASA’s Butch Wilmore and Suni Williams to return home from the International Space Station.

The mission to rescue two astronauts, including Needham native Sunita Williams, is now underway. After being postponed, NASA’s SpaceX Crew-10 had a successful launch Friday night. People in Needham are crossing their fingers that everything runs smoothly.
