NASA Prepares Artemis II Liquid Oxygen Tank for Next Phase of Assembly

This image shows the latest progress NASA has made in manufacturing the liquid oxygen tank for the second core stage of NASA’s Space Launch System (SLS) rocket. The liquid oxygen tank will be used for the first crewed mission, Artemis II, of the agency’s Artemis program. Teams at NASA’s Michoud Assembly Facility in New Orleans recently completed internal cleaning of the liquid oxygen, or LOX, tank at the facility. Following the cleaning, crews prepared the propellant tank for the next phase of phase of assembly in a different area of the factory by moving, or breaking over, the tank from a vertical to horizontal position. The LOX tank is one of five major elements that make up the rocket’s massive 212-foot-tall core stage. The propellant tank holds 196,000 gallons of supercooled liquid oxygen to help fuel four RS-25 engines, and the internal cleaning ensures no contaminants make their way into the complex propulsion and engine systems of the deep space rocket. The stage, which includes a cluster of four RS-25, will produce more than 2 million pounds of thrust to help launch the SLS rocket and astronauts aboard NASA’s Orion spacecraft around the Moon for Artemis II. NASA is working to land the first woman and the next man on the Moon by 2024. The agency’s SLS rocket offers more payload mass, volume capability and energy to speed missions through deep space and enable NASA’s Artemis lunar program. SLS, along with Orion, the human landing system, and the Gateway in orbit around the Moon are NASA’s backbone for deep space exploration. No other rocket is capable of carrying astronauts in Orion around the Moon in a single mission.
