Crews Move Artemis IV Liquid Hydrogen Tank

AI Insight

NASA crews at the Michoud Assembly Facility in New Orleans successfully transported a 130-foot-tall liquid hydrogen tank for the Artemis IV mission on May 15, 2026. The tank was moved from a production cell in the main factory building to a separate test facility on the 829-acre site. This component will be integrated into the core stage of the Space Launch System (SLS) rocket, where it will supply thousands of gallons of super-cold liquid hydrogen propellant to the RS-25 engines.


This represents a concrete step forward in NASA's Artemis program, which aims to establish sustained human presence on the Moon and eventually support crewed missions to Mars. The successful fabrication and testing of these massive fuel tanks is critical infrastructure development for deep space exploration missions.

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.
