The RS-25 test team at Stennis Space Center will hot-fire an untested flight engine on the A-1 Test Stand Thursday to help complete certification of design changes to fly on the Space Launch System (SLS). The test will be another step towards the flagship test firing of all four engines on the B-2 Test Stand.
Engine 2063 was assembled at Stennis from the hardware inventory inherited from the Space Shuttle Program.
It was installed in the A-1 test stand at the end of September to begin final preparations for the eight-minute long firing, which also serves as the acceptance test for the new engine.
The test marks one of the final requirements for certifying the SLS launch environment for the engines along with modern replacement computer hardware and software.
As adaptation of the former Space Shuttle Main Engine (SSME) design to the RS-25 is nearing completion, the four engines that will fly on the first SLS launch, Exploration Mission-1 (EM-1), are assembled and ready for integration, hopefully sometime next year.
