Ivan Ivanovich (Vostok programme)

Ivan Ivanovich (Иван Иванович, the Russian equivalent of "John Doe") was the name given to a mannequin used in testing the Soviet Vostok spacecraft in preparation for its crewed missions.

Ivan Ivanovich was made to look as lifelike as possible, with eyes, eyebrows, eyelashes, and a mouth. He was dressed in a cosmonaut suit and strongly resembled a dead person; for this reason, a sign reading "МАКЕТ" (Russian for "dummy") was placed under his visor so that anyone who found him after his missions would not think he was a corpse or an alien.
