Photos: Atlas 5 rocket soars from West Coast

SpaceX is readying two Falcon 9 rockets for a pair of flights nine hours apart Sunday from separate pads along Florida’s Space Coast. Weather permitting, the back-to-back departures Sunday would mark shortest span between two orbital-class launches from Cape Canaveral since 1966.

The last Delta 4-Medium rocket lifted off from Cape Canaveral Thursday with a GPS navigation satellite for the U.S. Air Force.

A Polar Satellite Launch Vehicle lifted off Friday with 31 satellites on the first flight for India’s workhorse rocket since an August mishap that left an Indian navigation satellite unusable after reaching orbit.
