At the review, NASA, Boeing, the core stage lead contractor, and Aerojet, the RS-25 engine prime contractor, gave the 'go' for proceeding with the test at NASA's Stennis Space Center near Bay St. Louis, Mississippi. In the coming days, the team will conduct systems checkouts and final inspections to ensure the core stage, its four RS-25 engines and the Green Run software and stage controller are ready for the hot fire. Engineers plan to power up the core stage on Tuesday, Feb. 23 ahead of the hot fire. The first SLS core stage hot fire test on Jan. 16, the first time all four engines were ignited, provided the team with significant data that informed process and procedures for the upcoming test.
