About Vostok

Vostok / Восток was a series of space craft built by the Soviet Union. Cosmonaut Yuri Gagarin became the first man in space on April 12th 1961 in Vostok-1. The Vostok program carried eight men into space until it was replaced in the late sixties by Soyuz. Amazingly, Soyuz spacecraft are still in use today 45 years later.
