upper stage engine is vital to achieving the full launch capability of the heavy-lift Space Launch System," said William Gerstenmaier, NASA's associate administrator for the Human Exploration and Operations Mission Directorate.
The successful powerpack test provided important data that verified the engine's components and gave us a better understanding of how the turbopumps operate," said Walt Janowski, J-2X
program manager, Pratt & Whitney Rocketdyne.
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.

powerpack tests were designed to evaluate the full range of operating conditions of the engine's components during flight.
The upcoming test series is not only a critical step forward, but important to the Stennis test team, as well," said Gary Benton, manager of the J-2X
test project at Stennis.
For the J-2X
engine this will enable a light weight design with maximized performance at a minimum of lead time and cost," he adds.
is based on a proven design that could provide a safe and reliable solution for NASA's future heavy-lift launch vehicles.
In addition to manufacturing the RD-180 and the RL10, Pratt & Whitney Rocketdyne is also developing the J-2X
engine to power NASA's next era of human spaceflight.

Testing is already underway on the J-2X
engine, which is planned for use in the SLS upper stage.
10, 2011 /PRNewswire/ -- Pratt & Whitney Rocketdyne and NASA successfully completed a 500-second duration hot-fire test on NASA's J-2X
engine, a key step in demonstrating the propulsion system's ability to power humans further into space than ever before.
