Technicians with NASA and Boeing complete attaching the engine section to the boat-tail for the agency’s Artemis III SLS (Space Launch System) rocket inside the high bay of the Space Systems Processing Facility at NASA’s Kennedy Space Center in Florida on Wednesday, Oct. 30, 2024. The engine section is one of five major elements that makes up the SLS rocket’s 212-foot-tall core stage, which house the rocket’s four RS-25 engines and vital systems for mounting, controlling, and delivering fuel from the stage’s two massive liquid propellant tanks to the engines. The boat-tail is designed to protect the bottom end of the core stage and the RS-25 engines.
