Two astronauts stranded in space will now remain there until late March or April as NASA delays launching their replacements. Their eight-day mission stretched to nearly eight months after NASA returned the faulty Starliner capsule empty in September. Astronauts Butch Wilmore and Sunita Williams traveled to the space station aboard the Starliner back in June. Their trip was initially only to last about eight to 10 days, but multiple issues with the Starliner prompted a concerned NASA, out of caution, to leave them behind at the space station and return the capsule to Earth empty in September.
