Media invited to J-2X engine test

STENNIS SPACE CENTER, Miss. - The media has been invited to NASA's John C. Stennis Space Center, Miss., next week to see the next test firing of the J-2X rocket engine, which will be used by NASA's Space Launch System. The test is Wednesday, Nov. 9. The SLS will carry the Orion spacecraft, its crew, cargo, equipment and science experiments beyond Earth orbit. Pratt and Whitney Rocketdyne is developing the J-2X for NASA's Marshall Space Flight Center in Huntsville, Ala. The SLS rocket engines will use a liquid hydrogen and liquid oxygen propulsion system, which will include the J-2X engine for the upper stage and RS-25D/E engines, Space Shuttle Main Engines, for the core stage.
