Artemis III Liquid Oxygen Tank Moves to Next Phase of Production

Move crews at NASA’s Michoud Assembly Facility in New Orleans move a liquid oxygen tank out of the facility’s vertical assembly building on Aug. 27, 2025. Using self-propelled mobile transporters teams transferred the tank to the final assembly production area. There, it will undergo integration of the forward dome by SLS (Space Launch System) prime contractor, Boeing. Eventually, the liquid oxygen tank will be moved back to the high bay where it will be mated with the intertank and forward skirt to complete the forward join of the Artemis III core stage. The propellant tank is one of five major elements that make up the 212-foot-tall rocket stage. The core stage, along with its four RS-25 engines, produce more than two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts, and supplies beyond Earth’s orbit and to the lunar surface for Artemis.
