More than 500,000 gallons of fuel will flow from the liquid hydrogen tank to the four RS-25 engines that power NASA’s Space Launch System rocket. During flight, and even during testing, a tank’s insides must be clean to ensure contaminants do not find their way into complex propulsion and engine systems. Technicians recently lifted the liquid hydrogen tank structural qualification test article into a cleaning cell at NASA’s Michoud Assembly Facility in New Orleans where its insides will be thoroughly cleaned, coated and dried to certify the process for the following flight article.
