At the Smithsonian National Air and Space Museum, they have curators for everything you would expect, like telescopes, missiles, planetary science and space shuttles. But Margaret Weitekamp’s collection is completely different. It includes things like ray guns, board games, pins, hats, t-shirts, and lunchboxes, all having something to do with space or space science fiction. Weitekamp’s title is Curator of the Social and Cultural Dimensions of Spaceflight, with a collection of more than 4,000 pieces of space-related ephemera to show for it. The Buck Rogers XZ-31 Rocket Pistol isn’t even the coolest piece of super-nerdy space stuff in her collection. Weitekamp’s principal obsession these days is an object that may resonate more deeply than anything else in museum’s collection, at least for the generation that grew up when America was going to the Moon.
