The Smithsonian Institution's National Air and Space Museum maintains the largest collection of historic air and space craft in the world. The collection includes more than 30,000 aviation-related and more than 9,000 space related artifacts（展品）. It is also a vital center for research into the history, science, and technology of aviation and space flight, as well as planetary science and terrestrial geology and geophysics.
The Museum has two display facilities. The National Mall building in Washington, D.C. has hundreds of artifacts on display including the original Wright 1903 Flyer, the Spirit of St. Louis, the Apollo 11 command module（指令舱）, and a lunar rock sample that visitors can touch. It is divided into 23 thematic exhibition galleries with names such as 'Milestones of Flight', 'Pioneers of Flight', 'Aviation in WWII' and 'Space Race'. The Steven F. Udvar-Hazy Center displays many more artifacts including the Lockheed SR-71 Blackbird, Boeing B-29 Superfortress Enola Gay and Space Shuttle Enterprise.

美国华盛顿宇航馆分上下两层，中间是挑高大厅。除了许多大型展品之外，还在空中悬挂着各种飞行器，即充分利用了空间，又显得十分壮观。展厅内共设20余个展区包括：飞行史上的里程碑、航空运输、飞行的黄金岁月、喷气式飞机、早期飞行器、如何飞行、看地球、探索宇宙、火箭与太空飞行、太空竞赛、IMAX影院、爱因斯坦天象仪、海-空作战、第二次世界大战中的飞行器、传奇的空中大战、探索行星、飞行的先锋、探索人类新的生存空间、阿波罗登月、超越极限等。几乎囊括了航空、航天的各个领域。
每个展区的设计都非常周密，从入口到出口始终引导参观者学习。例如：探索宇宙展区，入口处展板介绍了展区概况，展区内陈列着许多在人类探索宇宙过程中发挥重要作用的工具仪器，并介绍它们的作用和原理，包括：望远镜、浑天仪等。当观众参观结束时，又向观众提问：什么是宇宙？它有多大？它的年龄是多少？它的起源是什么？给人留下极为深刻的印象。
