National Air and Space Museum

One of the more adult-oriented museums on this list is the National Air and Space Museum in Washington, D.C., which is part of the amazing Smithsonian Institution. The Air and Space Museum spans two buildings, with the main campus in D.C. and the Steven F. Udvar-Hazy Center in Chantilly, Virginia. The main museum is undergoing a massive renovation, with plans to be open to the public toward the end of 2022. When it reopens, it will feature 23 reimagined exhibits with over 1,400 new pieces on display.

For the enjoyment of the more than 8 million guests who enter its doors each year, the National Air and Space Museum also presents changing exhibitions, talks, and events. The National Air and Space Museum's admittance is always free; no tickets are required. STEM in 30 and many teaching materials are available online. You won't believe this collection of peculiar items humanity have left behind on the moon, speaking of space. With exhibits on the moon landing and the Wright Brothers' initial flights, visitors may learn not only about the science of air and space travel but also about its historical development.
