The crew-swap mission will enable NASA’s Butch Wilmore and Suni Williams to return home from the International Space Station.

The flight was scrubbed on Wednesday night, and the astronauts will return to the launchpad for their trip to the International Space Station.

Butch Wilmore and Sunni Williams have spent nine months aboard the International Space Station following the failure of Boeing’s Starliner mission. Their rescue rocket has finally been launched.
