J-2X Gimbal Testing at Stennis Space Center

A closeup shot of the J-2X rocket engine shows how it was gimbaled during a June 14 test on the A-1 Test Stand at Stennis Space Center. A summer series of tests will be conducted on the advanced rocket engine, being developed for NASA by Aerojet-Rocketdyne of Canoga Park, Calif. The engine will prove upper-stage power for NASA's new heavy-lift Space Launch System vehicle, which will enable missions beyond low-Earth orbit. (NASA/SSC)
