This copper bar, about the size of a Popsicle stick, was created on board the Soviet Mir space station 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 in 1991.
Gift of Vladimir Dzhanibekov
