(AP) — The first astronauts launched by Elon Musk’s SpaceX company have left the International Space Station for the final and most important part of their test flight: returning to Earth with a rare splashdown. It will be the first splashdown for astronauts in 45 years — and the first return of a crew by SpaceX. NASA’s Doug Hurley and Bob Behnken bid farewell to the three men left behind as their SpaceX Dragon capsule undocked Saturday night. center_img The capsule is headed toward a Sunday afternoon descent into the Gulf of Mexico near Pensacola, on the opposite side of Florida from approaching Tropical Storm Isaias.last_img
