STENNIS SPACE CENTER, Miss. -- An Aerojet AJ26 engine had a successful hot fire test at Stennis Space Center Nov. 21. The test on the E1 test stand lasted the full duration 54 seconds, officials said. The AJ26 provides the power for the first stage of 133-foot tall Antares launch vehicle, built by Orbital Sciences Corp. In October, the Antares launched Orbital's Cygnus spacecraft on a successful mission to the International Space Station. In another test earlier this month, J-2X engine E10003 had a successful 50-second test on the A-2 test stand at SSC. (Source: GCAC, 11/26/13)
