J-2X rocket passes review

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 and Whitney Rocketdyne has an operation at Stennis.
