Finally! A replacement crew has arrived at the ISS, and Suni Williams and Butch Wilmore will come home at last.

NASA and SpaceX successfully launched the next ISS crew-rotation mission, Crew-10. The 10th operational crewed mission under NASA’s Commercial Crew Program, SpaceX’s Falcon 9 and Crew Dragon Endurance is carrying a crew of four NASA, JAXA, and Roscosmos astronauts to the orbiting laboratory for a six-month stay as part of Expedition 72/73.

NASA astronauts Butch Wilmore and Suni Williams arrived at the ISS aboard Boeing's Starliner spacecraft last June. The duo were flying the capsule's first crewed flight test, which was expected to stay in orbit for about 10 days before flying the pair back to Earth.

Suni Williams and Butch Wilmore, along with two other astronauts, boarded the SpaceX Dragon spacecraft and undocked from the International Space Station. Williams and Wilmore's nine-month stay on the ISS comes to a close as they are set to splash down off the coast in Florida on Tuesday.
