National Air & Space Museum on the National Mall

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 8 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.

The museum is currently transforming. Eight new galleries are now open, inviting visitors to explore air and space in new ways. The museum continues to work on transforming the building, reimagining more galleries. The reimagined galleries will open in phases over the next few years. While work continues, portions of the building will be closed. The full building is anticipated to be open in 2026.

Advance tickets are released 60 days out.

All visitors are required to pass through security.
