NASA will roll the fully assembled core stage for the agency’s SLS (Space Launch System) rocket that will launch the first crewed Artemis mission out of NASA’s Michoud Assembly Facility in New Orleans in mid-July. The 212-foot-tall stage will be loaded on the agency’s Pegasus barge for delivery to Kennedy Space Center in Florida.
The core stage is the backbone of the SLS rocket that will send a crew of four astronauts around the Moon in 2025. The stage’s two massive propellant tanks hold a collective 733,000 gallons of liquid propellant to power the four RS-25 engines at its base. Following hardware acceptance reviews and final checkouts, the stage will be readied for delivery for Artemis II launch preparations.
The rocket stage, with its four RS-25 engines, will provide more than two million pounds of thrust. Once at Kennedy, teams with NASA’s Exploration Ground Systems Program will finish outfitting the stage and prepare it for stacking and launch. Artemis II is currently scheduled for launch in September 2025.
Building, assembling, and transporting the core stage is a collaborative process for NASA, Boeing, the core stage lead contractor, and lead RS-25 engines contractor Aerojet Rocketdyne, an L3 Harris Technologies company.
