J-2X Engine Ready for 'Higher' Level of Tests
NASA Administrator Charles Bolden (r) takes an up-close look at the first development J-2X engine on the A-2 Test Stand at Stennis, where the engine is being prepared for a second round of testing. Pictured with Bolden is A-2 Test Stand Director Skip Roberts. The J-2X engine will provide upper-stage power for NASA’s evolved Space Launch System, a new heavy-lift launch vehicle capable of missions to deep space.
