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.

With favorable weather forecast at Kennedy Space Center’s Launch Complex 39A, NASA’s SpaceX Crew-10 mission is set to launch at 7:49PM ET tonight. Flying into orbit atop a SpaceX Falcon 9 rocket, the Dragon spacecraft, will dock with the ISS at around 6:00AM ET on March 13th.
