All 4 Engines Attached to the SLS Core Stage for Artemis I Mission

This photo shows all four RS-25 engines attached to the core stage for NASA’s Space Launch System rocket for the agency’s Artemis I mission to the Moon. To complete assembly of the rocket stage, engineers and technicians at NASA’s Michoud Assembly Facility in New Orleans are now integrating the propulsion and electrical systems within the structure. The completed core stage with all four RS-25 engines attached is the largest rocket stage NASA has built since the Saturn V stages for the Apollo Program that first sent Americans to the Moon. The stage, which includes two propellant tanks, provides more than 2 million pounds of thrust to send Artemis I to the Moon. Engineers and technicians attached the fourth RS-25 engine to the rocket stage Nov. 6 just one day after structurally mating the third engine. The first two RS-25 engines were structurally mated to the stage in October. After assembly is complete, crews will conduct an integrated functional test of flight computers, avionics and electrical systems that run throughout the 212-foot-tall core stage in preparation for its completion later this year. This testing is the first time all the flight avionics systems will be tested to
