NASA completed manufacturing of a hydrogen tank barrel that will be tested as a weld confidence article for the Space Launch System (SLS) rocket’s Exploration Upper Stage (EUS). Weld confidence articles help establish welding procedures and interfaces between the tooling and hardware and ensure the structural integrity of the welds. Starting with the Artemis IV mission, the EUS will provide the power to send astronauts in NASA’s Orion spacecraft and heavy cargo on a precise trajectory to the Moon.
