HUNTSVILLE, Ala. - NASA's high-performance rocket engine, the J-2X, completed a critical design review Thursday at Marshall Space Flight Center. The J-2X engine, developed by Pratt and Whitney Rocketdyne, is the first element of the Constellation Program to pass this design milestone. The engine will power the upper stage of the Ares I and the Earth departure stage of the Ares V heavy cargo launch vehicle. Michoud Assembly Facility in New Orleans and Stennis Space Center in Mississippi both are involved in the Constellation program. Pratt & Whitney Rocketdyne has an operation at Stennis.
