STENNIS SPACE CENTER, Miss. -- With testing of the J-2X engine completed April 10, engineers at Stennis Space Center are now focusing their attention on preparing the RS-25 engine for the test stands. Four RS-25 engines, previously known as space shuttle main engines, will power the core stage of Space Launch System that will take astronauts deeper into space than ever before. More than 200 feet tall with a diameter of 27.6 feet, the core stage will store cryogenic liquid hydrogen and liquid oxygen that will feed the RS-25s. Modifications to the engines, like higher thrust levels, were needed on the engines for the SLS. Gary Benton, J-2X and RS-25 test project manager at SSC, said the J-2X powerpack testing began in late 2007, and a wide range of full-engine developmental tests have been done. A number of J-2X tests benefit the upcoming RS-25 tests. (Source: NASA, 04/11/14) Background story: SSC does what's needed for stand
