NASA successfully completed a dress rehaersal for this month's flight of its unmanned X-43A research vehicle. A B-52 bomber carrying the X-43A/Pegasus booster combination left Edwards AFB, California last Monday afternoon at 15:21 PST, crossed the coast, and flew a predetermined path over the Pacific Missile Test Range. The B-52 and chase aircraft later returned to Edwards and landed at 17:28 PST.
The X-43A stack consists of a large solid fuel rocket tipped with the X-43A hypersonic research vehicle. Since this was a captive-carry mission, the stack remained attached to a pylon on the B-52's wing for the entire two-hour flight.
The mission was a dress rehaersal for a launch of the X-43A tentatively set for February 21st. The flight will evaluate supersonic combustion ramjet (scramjet) technology.
During last Monday's captive-carry mission, Ventura County residents spotted contrails and heard radio communications from the B-52 and chase aircraft.
