Powerpack test sets record

STENNIS SPACE CENTER, Miss. -- NASA's Stennis Space Center broke its own record Friday when it conducted a test on the new J-2X powerpack that lasted for 1,150 seconds, surpassing the previous record by more than a minute. For NASA the test marked a milestone step in development of a next-generation rocket engine to carry humans deeper into space than ever before. For SSC, the 19-minute, 10-second test represented the longest duration firing ever conducted in the center's A Test Complex. The powerpack is on the top of the J-2X engine and includes the gas generator, oxygen, fuel turbopumps and related ducts and valves. (Source: SSC/NASA, 06/08/12) Previous
