Pratt & Whitney Rocketdyne’s RS-25 engines, used in the space shuttle program, will undergo testing for use in the Space Launch System (SLS) rocket next year, once the test stand at the Stennis Space Center is upgraded. The engines have provided safe flight since 1981 with only one major malfunction during its flight history. Stennis’ A-1 Test Stand has to be adapted because it is specific to the J-2X and can’t be used for the RS-25, given that engine is much more powerful, with the ability to produce approximately 530,000 pounds of thrust.
