NASA's new deep space rocket, the Space Launch System (SLS), will launch missions powered by four RS-25 engines, reliable engines used for more than 135 space shuttle missions. The engines have been upgraded with new controllers and other features for SLS. Each engine has a unique number that allows engineers to track its flight history.
