Did you know that in 1977, 30 laboratory rats were sent into space? They launched on the satellite Kosmos 936 (also know as Bion 4) as part of an international research project that coordinated scientists from France, the United States, and the U.S.S.R. Join curator Cathleen Lewis as she reveals what the rats experienced in space and what the scientists learned.

Meet at the nose of the Lockheed SR-71 Blackbird in the Boeing Aviation Hangar.
