Another J-2X test slated

STENNIS SPACE CENTER, Miss. - NASA at Stennis Space Center is scheduled to conduct another test Thursday on the J-2X, the upper-stage rocket engine being developed by Pratt and Whitney Rocketdyne. Earlier this month NASA conducted a successful 500-second test of the engine, which will be used to carry humans, cargo and equipment beyond low-Earth orbit on the agency's new heavy lift Space Launch System. The J-2X uses liquid hydrogen and liquid oxygen propellants. (Source: NASA, 11/30/11) Previous post
