The space shuttle Discovery left the International Space Station behind having done everything it was scheduled to do and more. It is set to land Wednesday.
If all goes well and the space shuttle Discovery and its six-member crew return safely to Earth on Wednesday, the orbiter's final trip may well go down as the program's "above and beyond" mission.
Spacewalks and indoor tasks were performed so quickly and efficiently that managers added two days to Discovery's docked time at the space station to help the station crew get ahead on some jobs that would otherwise have fallen to space-station crew members.
Typically, "we don't do docked missions and add a couple of extra days," he said.
