Artemis IV’s 130-foot hydrogen tank reaches assembly building at NASA Michoud

NASA Marshall said on October 3 that the 130-foot liquid hydrogen tank for Artemis IV had moved to the vertical assembly building at NASA Michoud. Teams will next attach roll rings in preparation for primer application. The tank is part of the SLS core stage and will hold thousands of gallons of super-cold propellant for the rocket’s four RS-25 engines.
