J-2X Core Component Tests Completed

Engineers at NASA’s John C. Stennis Space Center are wrapping up the first series of tests on core components for the J-2X engine that will power the upper stage of the Ares I crew launch vehicle and the Ares V cargo launch vehicle. The Ares rockets are key elements of NASA‘s Constellation Program to return humans to the moon. This series of tests is providing valuable information for Pratt & Whitney Rocketdyne engineers as they upgrade pump and gas generator components in development of the new J-2X engine. Following this test series, Stennis workers will begin maintenance and mods on the A-1 Test Stand, preparing it for the next round of tests on an upgraded power pack in early 2010. The Stennis Space Center is NASA‘s primary center for rocket propulsion testing and is also the home of the Applied Research and Technology Project Office.
