US astronauts Barry Wilmore (61) and Sunita Williams (58) are having a ‘Major Tom’ moment aboard the International Space Station (ISS). They arrived on June 6 for an 8-day mission but became stuck in space after their Boeing CST-100 Starliner spacecraft suffered a malfunction with its helium-powered thrusters. Already stranded for two months, the astronauts may have to wait until February - another six months - for a ride home. Yesterday, NASA suggested it may turn to SpaceX for help.
