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.
When the next Delta 4 rocket flies in July, as well as all future ones to come, the enhanced RS-68A main engine will power the boosters off the launch pad.
The harbor at Vandenberg Air Force Base in California received a Delta 4 rocket last week, dropping anchor aboard the Delta Mariner cargo ship after transit from the manufacturing plant in Alabama.
