In a first, SpaceX launches national security satellite with previously flown booster

A SpaceX Falcon 9 rocket propelled a third-generation Global Positioning System navigation satellite into orbit Thursday in the first launch of a national security payload using a previously flown booster. Program officials say the move will save $64.5 million over three missions.

The rocket's nine first stage engines roared to life on time at 12:09 p.m. EDT, pushing the 229-foot-tall rocket away from pad 40 at the Cape Canaveral Space Force Station. After powering the Falcon 9 out of the thick lower atmosphere, the first stage fell away and headed for landing on a SpaceX droneship stationed in the Atlantic Ocean. On-board cameras provided spectacular views as the booster swooped to touchdown, chalking up SpaceX's 66th successful recovery at sea and its 88th overall.
