English: The core stage liquid hydrogen tank for the Artemis III mission completed proof testing, and technicians returned it to the main factory building at NASA’s Michoud Assembly Facility in New Orleans where it will undergo more outfitting. As part of proof testing, technicians apply a simple soap solution and check for leaks by observing any bubble formation on the welds. The technician removed the bubble solution with distilled water and then dried the area of application to prevent corrosion. To build the Space Launch System (SLS) rocket’s 130-foot core stage liquid hydrogen tank, engineers use robotic tools to weld five-barrel segments. This process results in a tank with around 1,900 feet, or more than six football fields, of welds that must be tested by hand. After the leak tests, the core stage lead, Boeing, pressurized the SLS tank to further ensure there were no leaks. After it passed proof testing, technicians moved the Artemis III liquid hydrogen tank to Michoud’s main factory. Soon, the technicians will prime and apply a foam-based thermal protection system that protects the tank during launch. Later, the tank will be joined with other parts of the core stage to form the entire 212-foot rocket stage with its four RS-25 engines that produce 2 million pounds of thrust to help launch the rocket. Artemis III will land the first astronauts on the lunar surface. Photographed on Monday, April 18, 2022. Image credit: NASA/Michael DeMocker |
