What the National Air and Space Museum is and where to find it
The National Air and Space Museum is a Smithsonian Institution museum in Washington, D.C. that holds the world's largest collection of aircraft and spacecraft. The museum is free to enter and open to the public year-round. It occupies two buildings: the main museum on the National Mall at Independence Avenue SW and 6th Street SW, and the Steven F. Udvar-Hazy Center near Washington Dulles International Airport in Virginia.
The main building on the National Mall is the one most visitors go to first. It sits between the U.S. Capitol and the Lincoln Memorial, making it straightforward to reach by Metro or car. The Udvar-Hazy Center is about 30 miles away and requires a separate trip, though admission there is also free.
Both locations house real aircraft and spacecraft that flew in actual missions. You will see the Wright Flyer, the Apollo 11 command module, the Space Shuttle Discovery, and thousands of other objects. The museum does not charge entry fees because it is a federal institution funded by Congress.
Key Takeaways
- The main National Air and Space Museum on the National Mall is free and open daily, with no ticket required, though timed passes are recommended during peak seasons.
- The museum holds the actual spacecraft and aircraft from historic missions, including the Wright Flyer, Apollo 11 command module, and Space Shuttle Discovery.
- The Steven F. Udvar-Hazy Center near Dulles Airport is a separate location with additional aircraft and requires its own visit, though admission is also free.
- Visiting hours, current exhibits, and any temporary closures are posted on the official Smithsonian website, which is the only reliable source for real-time information.
How to get to the main museum on the National Mall
The main building sits at Independence Avenue SW and 6th Street SW in Washington, D.C. If you are using public transit, the Metro's Blue, Orange, and Silver lines stop at the L'Enfant Plaza station, which is a five-minute walk from the museum entrance. The Red line also stops at Gallery Place-Chinatown, which is about a ten-minute walk away.
If you are driving, street parking near the National Mall is limited and often full during daytime hours. The Smithsonian Institution operates a parking garage at 900 Jefferson Drive SW, about two blocks from the museum. Paid parking is also available at several private lots in the area. Many visitors find it faster to use Metro than to search for parking.
The museum is located on federal land, so it is accessible to visitors with mobility needs. Elevators, accessible restrooms, and wheelchair rental are available inside. The main entrance is at ground level on Independence Avenue.
What to bring and what the museum provides
Bring comfortable walking shoes because the museum is large and you will cover significant distance. The main building spans three floors and contains 23 galleries. Most visitors spend two to four hours here, though you could spend a full day if you read all the text and watch all the videos.
The museum provides free maps at the information desk near the main entrance. Maps show the location of each gallery, restrooms, water fountains, and food options. You can also read a map from the Smithsonian website before you visit. The museum has a cafeteria and a smaller food court, so you do not need to bring your own food, though you may if you prefer.
Bags are subject to security screening at the entrance, similar to airport security. Large bags, weapons, and certain other items are not permitted. The museum's website lists prohibited items in detail. Strollers are permitted, and the museum provides stroller parking in some galleries if you need to leave yours temporarily.
Timed passes and how to get them
During busy seasons (spring and summer, plus school holidays), the museum uses a timed-pass system to manage crowds. A timed pass reserves your entry time and guarantees you can enter during that window. Timed passes are free, just like admission itself, but you must reserve one in advance on the Smithsonian website.
During slower seasons (fall and winter weekdays), timed passes may not be required, but checking the website before you go is still wise because requirements change. The website shows whether passes are required on the date you plan to visit and allows you to reserve one if needed.
If you arrive without a timed pass on a day when they are required, you may not be able to enter, or you may have to wait several hours. Reserving online takes five minutes and costs nothing, so it is worth doing even if you are not sure whether you need one.
The Steven F. Udvar-Hazy Center near Dulles Airport
The Udvar-Hazy Center is a separate museum building located at Washington Dulles International Airport, about 30 miles west of downtown Washington. It houses large aircraft that do not fit in the main building, including the Space Shuttle Discovery's backup orbiter, the Enola Gay (the B-29 bomber that dropped the atomic bomb on Hiroshima), and the Concorde supersonic jet.
Admission is free, but parking costs $15 per vehicle. The parking fee is the only cost associated with visiting this location. The center is open daily and does not require timed passes, though you should check the Smithsonian website for current hours because they vary by season.
The drive from the main museum takes 45 minutes to an hour depending on traffic. Many visitors combine a visit to the main museum with a trip to Udvar-Hazy, but it requires planning because the two locations are far apart. Some visitors choose to visit only one location on a single trip.
Current exhibits and what changes
The museum rotates temporary exhibits throughout the year in addition to its permanent galleries. Permanent galleries cover topics like the history of flight, space exploration, aviation technology, and the Apollo program. These galleries remain open year-round, though individual artifacts may be rotated out for conservation or loan to other institutions.
Temporary exhibits run for several months and then close. The Smithsonian website lists all current and upcoming temporary exhibits with their opening and closing dates. Some temporary exhibits are popular and draw large crowds, which is another reason to check the website and plan your visit in advance.
The museum occasionally closes individual galleries or sections for maintenance or renovation. The website shows which areas are currently open and which are temporarily closed. If there is a specific artifact or gallery you want to see, checking the website first prevents a wasted trip.
Planning your visit with children or in a group
The museum is designed for visitors of all ages. Young children can enjoy looking at the aircraft and spacecraft, though they may not read all the text panels. The museum provides activity guides for children at the information desk, and some galleries have interactive displays that children can use.
If you are visiting with a large group, consider arriving early in the day or visiting on a weekday rather than a weekend. Weekends and afternoons are busier. School groups often visit during the week, so even weekdays can be crowded during the school year. Early morning (right when the museum opens) is usually the quietest time.
The museum does not require advance registration for groups, but groups of 10 or more may want to contact the museum in advance to discuss their visit. The Smithsonian website provides contact information for group visits. Docent-led tours are sometimes available, though you should check the website to see whether tours are currently being offered.
Frequently Asked Questions
Do I need to buy a ticket to enter the National Air and Space Museum?
No. Admission is free because the museum is a Smithsonian Institution funded by the federal government. You do not pay to enter. During busy seasons, you must reserve a free timed pass in advance on the Smithsonian website, but the pass itself costs nothing.
Can I take photographs inside the museum?
Yes, personal photography is permitted in most galleries for non-commercial use. Flash photography is not permitted because it can damage artifacts and disturb other visitors. Tripods and professional camera equipment require permission from museum staff. Check the Smithsonian website or ask at the information desk if you have questions about a specific type of photography.
How long does it take to see everything?
Most visitors spend two to four hours at the main museum. The building is large, and you can spend as little or as much time as you want. If you read every text panel and watch every video, you could easily spend a full day. If you focus on the most famous artifacts, two hours is usually enough.
Is the museum accessible for people with disabilities?
Yes. The museum has elevators, accessible restrooms, and wheelchair rental at no cost. Visitors with mobility needs can navigate all three floors. Service animals are permitted. If you have specific accessibility questions, contact the museum through the Smithsonian website before your visit.
What is the difference between the main museum and the Udvar-Hazy Center?
The main museum on the National Mall has smaller aircraft and spacecraft organized by topic, with extensive text and interactive displays. The Udvar-Hazy Center near Dulles Airport displays large aircraft that do not fit in the main building, with less text and a warehouse-like setting. Both are free, but Udvar-Hazy charges $15 for parking. Most first-time visitors go to the main museum.
