NASA readies for J-2X testing

STENNIS SPACE CENTER, Miss. -- NASA's is getting ready for a new round of tests on the next-generation J-2X rocket engine that will help power the agency's Space Launch System to new destinations in the solar system. Beginning this month, engineers will conduct a series of tests on the second J-2X development engine, designated number 10002, on the A-2 Test Stand at NASA's Stennis Space Center. Once the series is completed, the engine will be transferred to the A-1 Test Stand to undergo a series of gimbal, or pivot, tests for the first time. NASA already has conducted successful tests on engine number 10001 and on the J-2X powerpack assembly. In total, 34 tests were conducted on the J-2X engine and powerpack, with the J-2X achieving a full flight-duration firing of 500 seconds in the eighth test, earlier than any rocket engine in U.S. history.
