American rocket engineer who designed the Viking rocket propulsion system. An early member of the American Rocket Society, Shesta was one of the founders of Reaction Motors, a company responsible for building many of the engines used in American space launch vehicles and missiles. As Milton Rosen wrote in The Viking Rocket Story: "Shesta was a conservative designer; he made the [Viking rocket] chamber overly large to ensure complete combustion and he chose an injector ... that, while not the best known, was reasonably sure to work."
