J-2X hot-fire test set for 2010

STENNIS SPACE CENTER, Miss. - The first hot-fire test of the J-2X engine that will power the Ares I is scheduled for late summer 2010 at John C. Stennis Space Center. The Pratt & Whitney Rocketdyne engine recently passed a Critical Design Review in Huntsville, Ala. The CDR means the engine can proceed to full-scale fabrication and assembly in preparation for development testing. (Source: PRNewswire, 11/19/08)
