Technicians used joysticks to operate transporters carrying the 149-foot-long liquid hydrogen tank structural test article on to NASA’s barge Pegasus, which will move the tank to NASA’s Marshall Space Flight Center in Huntsville, Alabama. Built by Boeing, the core stage prime contractor, the test hardware is structurally identical to the flight version of the liquid hydrogen tank that will comprise two-thirds of the core stage and hold 537,000 gallons of liquid hydrogen cooled to minus 423 degrees Fahrenheit. During flight propellant will flow from the tank to four RS-25 engines that will power the massive rocket on its first integrated flight with the Orion spacecraft: Exploration Mission-1.
