Sunday was homecoming day for the crew of the space shuttle Endeavour.
Stormy weather over Florida's Kennedy Space Center forced NASA to move the landing to Edwards Air Force Base in California.
Flight controllers prefer landings at Kennedy Space Center because of the cost.
NASA estimates it costs about 1-point-7 million dollars to bring a shuttle home to Florida from California.
It also takes at least a week to get the shuttle ready for the trip.
However, schedule is not a major factor for the Endeavour -- it's not scheduled to fly again until May.
Endeavour's mission to the international space station began on November 14 and included four spacewalks.
