NASA's Artemis II Moon Rocket Engine Moved into Position for Final Join

Technicians at NASA's Michoud Assembly Facility (MAF) in New Orleans, Louisiana, moved the engine section of NASA's Space Launch System (SLS) rocket for Artemis II, the first crewed mission to the Moon, into position for the final join of the core stage Feb. 22. The engine section is the bottom-most portion of the 212-foot-tall core stage. It is the last of five major elements that is needed to connect the stage into one major structure. In addition to its miles of cabling and hundreds of sensors, the engine section is a crucial attachment point for the four RS-25 engines and two solid rocket boosters that produce a combined 8.8 million pounds of thrust at liftoff and flight. During launch and flight, liquid propellants from the liquid hydrogen tank and liquid oxygen tanks are delivered through the engine section to the four RS-25 engines. The engine section also includes the avionics that help steer the engines after liftoff.

Next, teams will join the engine section to the core stage for the second SLS rocket. After the join is complete, teams will begin to add each of the four RS-25 engines one by one to complete the stage. The completely assembled stage with its four RS-25 engines will be shipped to NASA's Kennedy Space Center in Florida later this year. The SLS rocket is the only rocket capable of carrying astronauts in Orion around the Moon in a single mission.
