AJ26 performs second test fire

STENNIS SPACE CENTER, Miss. - NASA conducted a 55-second test fire Friday of the liquid-fuel AJ26 engine that will power the first stage of Orbital Sciences' Taurus II space launch vehicle. Taurus II uses a pair Aerojet AJ26 rocket engines to provide first stage propulsion. The test on the E-1 test stand involved a team of Orbital, Aerojet, and Stennis. The test was the second in a series of verification tests. A third hot-fire test also is planned to verify tuning of engine control valves. The AJ26 engine is designed to power the Taurus II space vehicle on flights to low Earth orbit. NASA's partnership with Orbital was formed under the agency's Commercial Orbital Transportation Services joint research and development project to enable commercial cargo flights to the International Space Station. The company is under contract with NASA to provide eight cargo missions to the space station through 2015. (Sources: PRNewswire, NASA, 12/17/10)
