“SLS is not a paper rocket,” Steve Cook, director of space technology at Dynetics, said Friday at the U.S. Space and Rocket Center. Cook guided the audience through a power point presentation showing work that has already been done over the last six years under different program names. Cook presented slides of boosters, engines, test firings, and core components like batteries and computers for a heavy lift rocket that have been achieved at Marshall Space Flight Center and other NASA centers like Stennis in Mississippi and Michoud in Louisiana. “The physics doesn’t change. A lot of work has already been done,” he said.”
