File images of Boeing's Starliner spacecraft and the two NASA astronauts it brought aboard the International Space Station in early June. The return of Barry "Butch" Wilmore and Sunita "Suni" Williams has been delayed by thruster malfunctions of the Boeing spacecraft. The astronauts will have to return home with rival SpaceX, NASA said Saturday. "NASA has decided that Butch and Suni will return with Crew-9 next February, and that Starliner will return uncrewed," NASA administrator Bill Nelson told reporters. AFP/FILE IMAGES
