The first human spaceflight was undertaken on April 12, 1961, when cosmonaut Yuri Gagarin made one orbit around the Earth aboard the Vostok 1 spacecraft, launched by the Soviet space program and designed by the rocket scientists Sergey Korolyov and Kerim Kerimov.
Since that time only a further 500 people have followed Yuri Gagarin into space.
