J-2X Powerpack Completes Testing

From the creator

The J-2X powerpack assembly was fired up one last time on Dec. 13 at NASA's Stennis Space Center in Mississippi, finishing a year of testing on an important component of America's next heavy-lift rocket. The powerpack assembly burned millions of pounds of propellants during a series of 13 tests during 2012 totaling more than an hour and a half. NASA engineers will remove the assembly from the test stand to focus on tests of the fully integrated engine. Installation on a test stand at Stennis will begin in 2013. The powerpack is a system of components on top of the engine that feeds propellants to the bell nozzle of the engine to produce thrust. The J-2X engine, designed and built by NASA and industry partner Pratt & Whitney Rocketdyne of Canoga Park, Calif., will power the upper stage of the 143-ton (130-metric-ton) Space Launch System (SLS) rocket. The SLS will launch NASA's Orion spacecraft and other payloads from the agency's Kennedy Space Center in Florida.
