SSC starting powerpack tests
STENNIS SPACE CENTER, Miss. -- A new series of tests on the J-2X engine that will power the upper stage of NASA's Space Launch System will begin next week. The tests will be on the J-2X powerpack, which is on the top portion of the J-2X. It includes the gas generator, oxygen and fuel turbopumps and related ducts and valves that bring the propellants together to create combustion and generate thrust. About a dozen powerpack tests of varying lengths are slated through summer at Stennis' A-1 Test Stand. The J-2X is being developed by Pratt and Whitney Rocketdyne. (Source: NASA, 01/25/12)
