(AP) -- Space shuttle Discovery has left the international space station.
Discovery undocked from the space station Tuesday afternoon as the two craft soared over China. Its departure ended more than a week of linked flight, in which tons of supplies and equipment were dropped off. The shuttle and its crew of seven are due back on Earth on Thursday.
Six astronauts were left behind on the orbiting outpost to continue their own lengthy missions.
The two crews embraced and said goodbye late Monday.
NASA, meanwhile, says it will not have to move the space station out of the way of a piece of space junk that will come within 15 miles Wednesday. It's a fragment from a Chinese satellite that was blasted by a missile two years ago.
