NASA Attaches First of 4 RS-25 Engines to Artemis I Rocket Stage

Engineers and technicians at NASA’s Michoud Assembly Facility in New Orleans have structurally mated the first of four RS-25 engines to the core stage for NASA’s Space Launch System rocket that will help power the first Artemis mission to the Moon. Integration of the RS-25 engine to the recently completed core stage structure is a collaborative, multistep process for NASA and its partners Boeing, the core stage lead contractor, and Aerojet Rocketdyne, the RS-25 engine lead contractor.
