Get a sneak peek behind the scenes of how engineers and technicians at Orbital ATK in Promontory, Utah, come together to test the most powerful booster for NASA’s next generation rocket, the Space Launch System (SLS). SLS will make missions into deep space possible, traveling to the moon and beyond, and one day, to the red planet. For more information on SLS, visit nasa.gov/sls.
