Artemis III Liquid Hydrogen Tank Moves to Final Assembly

NASA’s Michoud Assembly move crews lift the liquid hydrogen tank for its Artemis III mission out of a production cell and move it into the final assembly manufacturing area on Oct. 10, 2025. Teams with SLS (Space Launch System) prime contractor, Boeing, recently mated the tank to the LH2 Transport Adapter Assembly, which will allow the stage to be securely transported by barge to NASA’s Kennedy Space Center once it’s mated to the forward end of the core stage. The LH2 Transport Adapter Assembly serves as a temporary place holder for the engine section, which was previously shipped from Michoud to NASA’s Kennedy Space Center for further integration. 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.
