NASA has decided it's too risky to return two astronauts to Earth using Boeing's new capsule. Instead, Butch Wilmore and Suni Williams will return next year with SpaceX. Originally planned as a week-long test, their mission has now extended to over eight months. The astronauts have been at the International Space Station since June. After three months of deliberation, NASA announced that their empty Starliner capsule will undock in early September and land in the New Mexico desert.
