CAPE CANAVERAL, Fla. - Mission Control says the weather looks `pretty iffy' tomorrow for the shuttle Endeavour's return to the Kennedy Space Center.
A cold front is expected, bringing stiff winds and possible thunderstorms. Endeavour has enough supplies to stay aloft until Tuesday if need be.
Meanwhile, NASA is studying new images of the shuttle's heat shield to make sure it's ready for re-entry. A small ding was found on a window earlier this week, but analysts don't think it's any danger.
The seven astronauts are eager to get home.
Besides preparing to land, they're also doing a round of TV interviews, and releasing a tiny Pentagon satellite to test solar cell technology.
The three crew members aboard the International Space Station have the day off. But early tomorrow a Russian cargo ship arrives.
