National Air and Space Museum

The museum was created by Congress in 1946 to preserve and interpret the nation's aviation heritage, then became the National Air and Space Museum when its mission expanded to include spaceflight.¹ Its principal building opened on the National Mall in 1976 as part of the United States Bicentennial celebrations. The museum's purpose is broader than displaying famous machines: it connects technological artifacts with military history, commerce, science, engineering, popular culture, and the experiences of the people who designed and used them.

The Mall building was designed to accommodate very large objects while remaining accessible to a general audience. Its galleries present aviation and spaceflight as related but distinct histories, ranging from early powered flight to robotic exploration and human spaceflight. Smithsonian curators also use the collection for research, conservation, education, and public programs.¹

The collection's best-known objects are milestones whose historical importance is matched by their physical presence. They include the 1903 Wright Flyer, Charles Lindbergh's Spirit of St. Louis, the Apollo 11 command module Columbia, and the lunar module Intrepid.³ Together, these objects show how flight developed from experimental aeronautics into long-distance transport, military power, and crewed space exploration.

The holdings extend well beyond complete aircraft and spacecraft. The museum preserves engines, propellers, spacesuits, flight instruments, personal papers, photographs, works of art, technical drawings, and objects associated with everyday aviation. This breadth allows exhibitions to examine subjects such as navigation, air traffic control, women and African Americans in aerospace, commercial aviation, planetary science, and the social consequences of new technologies.⁴ Many collection objects are not normally on public view because they require specialized storage, conservation, or study.

The National Air and Space Museum operates two public sites: the National Mall museum in Washington, D.C., and the Steven F. Udvar-Hazy Center near Washington Dulles International Airport in Chantilly, Virginia.² The second site provides the high ceilings and expansive floor area needed for aircraft that cannot fit comfortably in the Mall building, including the Space Shuttle Discovery, the Lockheed SR-71 Blackbird, and the Air France Concorde.

The Washington museum combines permanent galleries with changing exhibitions, demonstrations, an IMAX theater, a planetarium, educational spaces, and public events. Because the building has undergone major modernization, gallery availability and visitor procedures can change; the Smithsonian publishes current information about timed entry, exhibitions, accessibility, and closures on its visitor pages.² The Udvar-Hazy Center also includes observation areas overlooking the nearby airport, linking its displays to continuing aviation activity.

The museum's less visible work is as important as its iconic exhibits: conservators stabilize fragile materials, historians document provenance, and specialists study artifacts as evidence rather than treating them merely as souvenirs of famous events.⁴ A spacecraft can therefore be significant for its engineering, its political context, or the traces of use left by astronauts and technicians.

The collection also preserves forms of flight that do not fit the conventional heroic narrative. It includes objects connected with unmanned spacecraft, atmospheric research, navigation, air commerce, military aviation, and the contributions of groups historically excluded from standard accounts of aerospace history. The museum's digital resources extend access to objects and stories that cannot be displayed simultaneously, while its research and education programs make the institution both a public museum and a scholarly center.¹
