NASA Readies Artemis II Liquid Hydrogen Tank for Next Phase of Manufacturing

This image highlights the liquid hydrogen tank that will be used on the core stage of NASA’s Space Launch System rocket for Artemis II, the first crewed mission of NASA’s Artemis program. The tank is being built at NASA’s Michoud Assembly Facility in New Orleans. 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 hydrogen tank holds 537,000 gallons of liquid hydrogen cooled to minus 423 degrees Fahrenheit and sits between the core stage’s 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 cores stage to produce more than two million pounds of thrust to launch NASA’s Artemis missions to the Moon. Together with its four RS-25 engines, the rocket’s massive 212-foot-tall core stage — the largest stage NASA has ever built — and its twin solid rocket boosters will produce 8.8 million pounds of thrust to send NASA’s Orion spacecraft, astronauts and supplies beyond Earth’s orbit to the Moon and, ultimately, Mars. Offering more payload mass, volume capability and energy to speed missions through space, the SLS rocket, along with NASA’s Gateway in lunar orbit, the human landing system, and Orion spacecraft, is part of NASA’s backbone for deep space exploration and the Artemis lunar program. No other rocket can send astronauts in Orion around the Moon in a single mission.
