NASA's test of the J-2X rocket engine on the A-2 Test Stand at Stennis Space Center on July 13 was picture perfect in more ways than one. Not only did the test provide a breathtaking view from atop the nearby A-1 Test Stand, and with the center's B-1/B-2 Test Stand in the background, but it achieved its target of 550 seconds. The test continued a series of firings to gather critical data for engine development.
