Six months after its unmanned spacecraft exploded shortly after liftoff, SpaceX is once again taking to the sky. The space exploration company is set to launch a spacecraft Monday night at Cape Canaveral Air Force Station, Florida. They’ve carried out more than 20 successful unmanned space missions since 2006, but SpaceX launches have been on hiatus since June. The liftoff could mark a comeback for the Tesla CEO Elon Musk and his team at SpaceX.
