Sword from the novel Glory Road by Robert Heilein

Art has a large collection of space related artwork including paintings and sculptures. Many works express scenes or themes from novels by Robert Heinlien.

Currently on display at the Smithsonian Air and Space Museum, this key prevented connection to the battery leads and was removed shortly before launch. This is the only remaining piece of the Sputnik satelite.
