Dec. 22 (UPI) -- Bad weather forced the fourth cancellation of a SpaceX launch Saturday from Florida with the next liftoff scheduled for Sunday.
The private company attempted to launch a GPS satellite for the Air Force from Cape Canaveral Air Force Station's launch pad 40 at 9:21 a.m. until it was scrapped because of "upper level winds," according to a Twitter post. The original launch window was 8:55 a.m.
