Deep space power trial
NASA's Stennis Space Center broke its own record when it conducted a test on the new J-2X powerpack. The test lasted for 1,150 seconds, surpassing the previous record by more than a full minute.
The test marked a milestone step in development of a next-generation rocket engine to carry humans deeper into space than before. For Stennis, the 19 minute, 10 second test represented the longest duration firing ever conducted in the center's A Test Complex.
“This is the longest and the most complex J-2X test profile to date,” said Mike Kynard, NASA's Space Launch System liquid engines element manager. “By combining as many test objectives as we can, we aim to get the most out of every opportunity and work as affordability and efficiently as possible while maintaining a reasonable level of risk.” The powerpack is a system of components on the top portion of the J-2X engine, including the gas generator, oxygen and fuel turbopumps, and related ducts and valves.
