The Crew-10 mission will send four astronauts to the space station to take over for Butch Wilmore and Suni Williams’ crew, finally allowing their return home.

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.
