RS-25 is the engine, once used in the Shuttle, but the last upgrade and received a new controller, which is considered one of the key changes. Its tasks include ensuring the connection between the engines and the rocket, the tracking of the ratio of fuel oxygen-hydrogen mixture and of the thrust level. The SLS will use four modified RS-25 engine, running concurrently, and a pair of solid rocket boosters.
