Crews Complete SLS Liquid Oxygen Tank Forward Dome for Artemis IV (Photo Release - July 11)

Teams completed welding of the liquid oxygen dome for the core stage of a future SLS (Space Launch System) rocket at NASA’s Michoud Assembly Facility in New Orleans.

The dome, which will cap off the forward end of the liquid oxygen tank, was lifted off of the robotic weld tool and moved to an assembly area for the next phase of production. Later, crews will add the forward dome to join the two barrels and the aft dome to complete the liquid oxygen tank.

The flight hardware will be used for Artemis IV, the first flight of SLS in its Block 1B configuration.

The SLS core stage liquid oxygen tank holds 196,000 gallons of super-cooled liquid propellant. 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 liquid oxygen and liquid hydrogen tanks will provide propellant to the four RS-25 engines to produce more than two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts and supplies beyond Earth’s orbit to the Moon.
