Sunita Williams and Butch Wilmore, the two astronauts stuck in space, will have to stay on the International Space Station (ISS) until next February. NASA says the pair will return on a SpaceX craft, rather than the Boeing Starliner that took them into space, because of a faulty propulsion system that is just too risky. As Jayme Doll reports, what was meant to be an eight-day trip is turning into an eight-month misadventure.
