STENNIS SPACE CENTER, Miss. -- NASA conducted its final J-2X rocket engine test of the year Wednesday, the 10th firing in a series on the upper-stage engine for the Space Launch System. The engine was test fired on the A-2 stand at 100 percent power for engine performance calibration and the effects of fuel inlet pressure variations. The engine, No. 10001, will be moved from the stand to allow for addition of a nozzle extension and associated test facility modifications needed for additional engine tests in 2012. J-2X engines 10002 through 10004 are being manufactured for hot fire testing at Stennis planned through 2014. In addition, tests of the J-2X powerpack are scheduled for 2012. On Thursday SSC is scheduled to test the Aerojet AJ26 engine. (Source:
