This copper bar is about the size of a Popsicle stick. It was rendered on board the Soviet space station Mir space station inside, as part of research on the benefits of microgravity in developing ultra-pure materials. The bar bears the inscription "cosmos (space) for the world" and a drawing of Soviet Buran space shuttle.
Cosmonaut Vladimir Dzhanibekov donated this bar to the National Air and Space Museum.
Gift of Vladimir Dzhanibekov
