CAPE CANAVERAL, Fla. (AP) - NASA is already warning the space shuttle astronauts to expect rain delays as they get ready to come home.
Discovery and its crew of seven are scheduled to land Monday morning in Florida.
Shuttle commander Alan Poindexter said Sunday that it's always great to spend extra time in orbit. He doesn't mind if Discovery can't make it back to Earth until Tuesday. Mission Control says it will keep monitoring the weather, just in case the forecast changes.
Only three shuttle flights remain. Pilot James Dutton Jr. says that was on his mind as he flew Discovery away from the International Space Station on Saturday. He says it was amazing to look back and "see that manmade creation up there, floating above the Earth."
