Crews at NASA’s Michoud Assembly Facility in New Orleans transport the 130-foot-tall Artemis IV liquid hydrogen tank out of a production cell inside the main factory building into a detached test building on a separate portion of the 829-acre site on May 15, 2026. The liquid hydrogen tank will form part of the core stage for the SLS (Space Launch System) rocket, providing thousands of gallons of super-cold propellant to one of four RS-25 engines.
