NASM's Steven F. Udvar-Hazy Center in Chantilly, VA is reopening on May 5th. That's the enormous hangar where the Space Shuttle Discovery, the Enola Gay, a Concorde, and other historic airplanes are on display. It's kind of hilarious that these are all called 'objects' on the website, which I suppose they are, from a museum curator's point of view.
