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 (SLS) rocket that will help power the first Artemis mission to the Moon. Integration of the RS-25 engines 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 engines lead contractor. To complete the installation, the technicians will now integrate the propulsion and electrical systems. The installation process will be repeated for each of the four RS-25 engines. The four RS-25 engines used for Artemis I were delivered to Michoud from Aerojet Rocketdyne’s facility at NASA’s Stennis Space…

NASA’s Pegasus Barge arrived at the Launch Complex 39 turn basin wharf at Kennedy Space Center in Florida to make its first delivery to Kennedy in support of the agency’s Artemis missions. The upgraded 310-foot-long barge arrived Sept. 27, 2019, ferrying the 212-foot-long Space Launch System rocket core stage pathfinder. Weighing in at 228,000 pounds, the pathfinder is a full-scale mock-up of the rocket’s core stage and will be used to validate ground support equipment and demonstrate it can be integrated with Kennedy facilities.
