NASA conducted the first hot-fire test of the year of an RS-25 rocket engine on the A-1 Test Stand at the John C. Stennis Space Center in Mississippi, on 16 January 2018, at 22:04 UTC (16:04 CST).
The “green run” 365-second, full-duration test was conducted as a certification test of another RS-25 engine flight controller installed on RS-25 developmental engine E0528 and fired just as during an actual launch. NASA’s Space Launch System (SLS) will be powered by four RS-25 engines firing simultaneously.
