Nevertheless, in the decades following World War II, rocketry, guided missiles, and space flights were rapidly developing a complex history and lore quite different from that of aviation. Accordingly, in 1965, the Museum established a Department of Astronautics parallel with a Department of Aeronautics. At that time, artifacts in categories of rocket propulsion, guided missiles, and space-flight programs were placed under curatorial control of the Astronautics Department. In 1967 the Smithsonian Institution and the National Aeronautics and Space Administration signed an agreement which provided for transfer of title to and custody of significant space artifacts by the Museum after their technical need had passed. Through provisions of this instrument the preservation and exhibit of this country’s most important spacecraft, rocket engines, launch vehicles, and missiles has been assured for posterity.
