NASA's J-2X Engine

"This image from 2008 shows NASA's J-2X engine. NASA conducted a 40-second test of the J-2X rocket engine Sept. 28, the most recent in a series of tests of the next-generation engine selected as part of the Space Launch System architecture that will once again carry humans into deep space. It was a test at the 99 percent power level to gain a better understanding of start and shutdown systems as well as modifications that had been made from previous test firing results."

    Hmm cool.... They should definitely post how this rocket will work and will it be more fuel efficient? This way if its not we can just go back to the drawing board rather than pour a couple more billion on a rocket that works the same as the other rockets but look slightly different.
