Orbital tests rocket at new pad

WALLOPS ISLAND, Va. -- NASA commercial partner Orbital Sciences of Dulles, Va., successfully conducted an engine test of its Antares rocket Friday at the nation's newest launch pad. The company fired dual AJ26 rocket engines for the full duration 29 seconds while the rocket was bolted down on the Mid-Atlantic Regional Spaceport (MARS) Pad-0A at NASA's Wallops Flight Facility on Wallops Island, Va. Known as a "hot fire" test, it demonstrated the readiness of the rocket's first stage and launch pad fueling systems to support upcoming test flights.
