The four RS-25 engines from Aerojet Rocketdyne successfully propelled the Core Stage, Interim Cryogenic Propulsion System, and Orion/Service Module stack into its initial Earth orbit during the system’s debut launch on Nov. 16, 2022.
The engines fired for a full duration of nearly eight and a half minutes, inserting the SLS stack into a 30 x 1,800 km initial Earth orbit trajectory before their destructive plunge with the Core Stage back into the atmosphere near the Hawaiian islands.
