Visit the 1903 Wright Flyer, Charles Lindbergh's Spirit of St. Louis, the Apollo 11 Command Module Columbia or touch an actual lunar rock. Visitors can also perform 360-degree barrel rolls in a flight simulator, observe sunspots at the observatory or check out a 3-D film on the IMAX theater's five-story tall screen.Best and worst times to go to Smithsonian National Air and Space MuseumWhile the museum is nearly always busy, the crowds are much thinner in the fall and winter months.

Avoid the summer months when the region often experiences high humidity and temperatures that can hit 100 degrees as well as high crowd volume.Must see/do at National Air and Space MuseumOne of the most visited museums in the world for good reason, there's no shortage of amazing exhibits and it's easy to be overwhelmed by all there is to see and do. So don't try to do it all. Don't miss the opportunity to touch an actual moon rock, see the 1903 Wright Flyer, take a look inside the Apollo 11 Command Module Columbia or eat the same ice cream eaten by astronauts in space.Admission to Smithsonian National Air and Space MuseumThe National Air and Space Museum is open from 10 a.m. to 5:30 p.m. daily, except December 25.
