NASA’s Marshall Space Flight Center (MSFC) announced the successful completion of subscale-main-injector hardware, an early step in the development of the RS-68 engine that would power the core stage of NASA’s Ares-V. Under the Constellation Program, Ares-V would serve as NASA’s cargo launch vehicle, delivering large-scale hardware and systems to space, in support of NASA’s exploration missions to the Moon. MSFC engineers had conducted multiple hot-fire tests on the inject hardware, a major component of the engine. The hardware would inject and mix liquid-hydrogen and liquid-oxygen propellants in the engine’s combustion chamber, where they would ignite and burn to produce thrust. Because injector hardware for the RS-68 and the J-2X engine systems shared design features, engineers planned to use data collected during the tests to develop the J-2X engine systems for the upper stages of Ares-V and for Ares-I, the crew launch vehicle (CLV) that would carry the Orion spacecraft.
