US astronauts prepare for SpaceX-NASA return home from ISSThe first US astronauts to reach the International Space Station on an American spacecraft in nearly a decade prepared Saturday for their return home, which is tentatively on schedule for the weekend despite the arrival of Hurricane Isaias off Florida. "Now is the entry, descent and splashdown phase after we undock, hopefully a little bit later today," Doug Hurley, one of the two astronauts, said in a farewell ceremony aboard the ISS that was broadcast on NASA TV.
