Crews at NASA’s Michoud Assembly Facility in New Orleans transport the 130-foot-tall liquid hydrogen tank out of a production cell inside the main factory building into a detached test building on a separate portion of the 829-acre site. The liquid hydrogen tank will form part of the core stage for the SLS (Space Launch System) rocket, providing thousands of gallons of super-cold propellant to one of four RS-25 engines. Inside the test cell, teams will perform non-destructive evaluation proof testing on the tank. Proof testing ensures the structural integrity of the flight hardware before crews begin the next phase of production. The liquid hydrogen propellant tank is one of five major elements that make up the 212-foot-tall SLS rocket stage. The core stage, along with its four RS-25 engines at its base, produce more than two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts, and supplies beyond Earth’s orbit and to the lunar surface for Artemis.
