Liquid Hydrogen Tank for Artemis III Moves on to Next Phase of Production. Technicians at NASAs Michoud Assembly Facility in New Orleans move the liquid hydrogen tank of NASAs Space Launch System (SLS) rocket to Cell A for white light scans of the tanks dimensions in preparation of multiple join activities throughout the manufacturing process. The flight hardware will be used for Artemis III, one of the first crewed Artemis missions.The liquid hydrogen tank holds 537,000 gallons of liquid hydrogen cooled to minus 432 degrees Fahrenheit and is the largest of the five elements that make up the rockets 212-foot-tall core stage. The liquid hydrogen tank is situated between the core stages intertank and engine section. The liquid hydrogen hardware, along with the liquid oxygen tank, will provide propellant to the four RS-25 engines at the bottom of the core stage to produce more than two million pounds of thrust to launch NASAs Artemis missions to the Moon.Together with its four RS-25 engin
