During a record-breaking June 8 test, engineers throttled the J-2X powerpack up and down several times to explore numerous operating points required for the fuel and oxidizer turbopumps. The results of this test will be useful for determining performance and hardware life for the J-2X engine turbopumps. The J-2X engine will power the upper stage of the evolved NASA¹s Space Launch System, an advanced heavy-lift rocket that will provide an entirely new national capability for human exploration beyond Earth¹s orbit. The test was conducted at NASA's John C. Stennis Space Center in south Mississippi. Pratt & Whitney Rocketdyne is developing the J-2X engine for NASA¹s Marshall Space Flight Center in Huntsville, Ala.
