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.

The quartet will head to the International Space Station for a roughly six-month stay. They'll relieve four other astronauts — NASA's Nick Hague, Suni Williams and Butch Wilmore and cosmonaut Aleksandr Gorbunov, who will come back to Earth a few days after Crew-10 docks.
