CAPE CANAVERAL, Fla. - NASA says rain could delay space shuttle Discovery's return to earth.
The shuttle was scheduled to land Monday morning at Cape Canaveral. But NASA is considering a delay due to rain showers expected over the landing site.
Shuttle commander Alan Poindexter says he doesn't mind spending extra time in orbit. The astronauts have enough supplies to stay in orbit until Wednesday. In a worst-case scenario, Discovery could land at a back-up site in southern California.
