Phase one of this study, Astronomy and Astrophysics: A National Historic Landmark Theme Study was completed in l989. Subsequent phases of the science theme study will include the disciplines of biology, chemistry, mathematics, physics and other related sciences. The Science Theme Study is being completed by the National Historic Landmarks Survey of the National Park Service in compliance with the requirements of the Historic Sites Act of l935. The Historic Sites Act established "a national policy to preserve for public use historic sites, buildings and objects of national significance for the inspiration and benefit of the American people." Under the terms of the Act, the service is required to survey, study, protect, preserve, maintain, or operate nationally significant historic buildings, sites & objects. The National Historic Landmarks Survey of the National Park Service is charged with the responsibility of identifying America's nationally significant historic property. The survey meets this obligation through a comprehensive process involving thematic study of the facets of American History. In recent years, the survey has completed National Historic Landmark theme studies on topics as diverse as the American space program, World War II in the Pacific, the US Constitution, recreation in the United States and architecture in the National Parks.
