On May 25, 2012, NASA recorded another first during a 40-second test of the next-generation J-2X engine on the A-2 Test Stand at Stennis Space Center. Test conductors fired the J-2X in both the secondary and primary modes of operation. Previous tests were run in one mode only; combining the two allowed operators to collect critical data on engine performance.
