This image highlights the liquid oxygen tank, which will be used on the core stage of NASA Space Launch System rocket for Artemis II, the first crewed mission of NASAs Artemis program, at NASAs Michoud Assembly Facility. The SLS core stage is made up of five unique elements: the forward skirt, liquid oxygen tank, intertank, liquid hydrogen tank, and the engine section. The forward skirt houses flight computers, cameras, and avionics systems. The liquid oxygen tank holds 196,000 gallons of liquid oxygen cooled to minus 297 degrees Fahrenheit. The LOX hardware sits between the core stages forward skirt and the intertank. Along with the liquid hydrogen tank, it will provide fuel 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 engines, the rockets massive 212-foot-tall core stage — the largest stage NASA has ever built — and its twin solid rocket
