At Air and Space, Part I

One of the best museum to go to in Washington. Everything from a space suit, the V-2 and V-1 and the Hubble telescope.

As their website states:

The Smithsonian Institution's National Air and Space Museum maintains the largest collection of historic air and spacecraft in the world. 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.

It is a great museum and well worth a visit.
