A squirrel monkey, his body swathed in protective silicon rubber padding, is strapped into a capsule as part of a training exercise for spaceflight.

Though it is believed that Gordo survived the entirety of his flight, the parachute on his craft failed to open and he and his capsule were lost at sea.
