SLS Liquid Hydrogen Tank Test Article Loaded into Test Stand
The largest piece of structural test hardware for America’s new deep space rocket, the Space Launch System, was loaded into Test Stand 4693, which was constructed by Brasfield & Gorrie at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The liquid hydrogen tank is part of the rocket’s core stage, which is more than 200 feet tall and has a diameter of 27.6 feet. The tank stores cryogenic liquid hydrogen and liquid oxygen that will feed the vehicle’s RS-25 engines. Dozens of hydraulic cylinders in the 215-foot-tall test stand will push and pull the tank, subjecting it to the same stresses and loads it will endure during liftoff and flight.
