Final preparations are underway for the launch mission to bring back NASA astronauts Suni Williams and Butch Wilmore home to Earth. NBC News’ Marissa Parra has the latest details on the mission as both astronauts have now spent nine months in orbit since they launched on the first crewed test of Boeing’s Starliner spacecraft last June.

The crew of the infamous Boeing Starliner should be able to return to Earth in a matter of days with the imminent arrival of a replacement mission at the International Space Station. Four spacefarers who are part of a SpaceX mission known as Crew-10 are due to launch into orbit Wednesday night from Florida.
