Their success even earned the crew praise from President Barack Obama.

The space shuttle and its crew of six were scheduled to return to NASA's spaceport Sunday night, but the weather concerns were threatening to dampen those plans. During the two-week mission, the crew added a new room and a dome with seven windows at the International Space Station. Their success even earned the crew praise from President Barack Obama. On Saturday, the chairman of the mission management team LeRoy Cain, said there was a 50-50 chance that the weather would cooperate. "We're always hopeful, and I guess I would call it optimistic," Cain told reporters. Edwards Air Force Base in California will serve as a back up in case Florida's weather prevents the landing in Cape Canaveral. By Monday, weather conditions are forecasted to be worse at the site in Florida, but improve in California. The space shuttle has enough power and supplies to stay in Orbit until Tuesday. "We're a long ways away, meteorologically speaking, so there are a lot of ways this could turn out," Cain said. The mission was delayed in its liftoff because of poor weather conditions. Meanwhile, crews on the ground were trying to determine if the shuttle had suffered any micro meteorite damage. Two of the shuttle's windows suffered small dings from bits of space junk, but it was not expected to cause any problems as it re-enters the earth's atmosphere. The next shuttle launch is set for early April.
