The Smithsonian's National Air and Space Museum maintains the world's largest and most significant collection of aviation and space artifacts, encompassing all aspects of human flight, as well as related works of art and archival materials. It operates two landmark facilities that, together, welcome more than eight million visitors a year, making it the most visited museum in the country. It also is home to the Center for Earth and Planetary Studies. One Museum, Two Locations The Museum's two buildings house thousands of artifacts showcased in exhibitions on aviation, space exploration, and planetary science. At both of its locations, the Museum presents programs, educational activities, lectures, and performances that reflect the American spirit, and the innovation, courage, and optimism that have led to triumphs in the history, science and technology of flight. At the Museum in Washington, DC, which opened in 1976 and is located in the heart of the Smithsonian complex in Washington, DC, some of the most awe-inspiring icons of flight are on display. The Steven F. Udvar-Hazy Center, located near Washington Dulles International Airport in Chantilly, Virginia, is a massive structure with open, hangar-like settings that accommodate large aircraft and spacecraft, as well as entire collections of aviation and space artifacts.
