The forecast of stormy weather prevented rollback of the mobile service gantry and the continuation of the countdown at Cape Canaveral on Wednesday for the United Launch Alliance Delta 4 rocket.
The launch of the seventh Wideband Global SATCOM military communications satellite aboard a Delta 4 rocket booster occurred tonight at 8:07 p.m. EDT (0007 GMT) from Cape Canaveral.
Using a new, uprated main engine for the first time on a rocket of its kind, a United Launch Alliance Delta 4-Medium+ vehicle will soar into space Wednesday night carrying a $566 million Air Force communications satellite.

With the Delta 4 rocket now waiting on the launch pad, its Air Force Wideband Global SATCOM communications satellite payload has jetted from the Los Angeles factory to the Cape Canaveral in preparation for liftoff this summer.
