Yuri Gagarin proved humans have future in space
It was the Soviet Union's own giant leap for mankind, one thatwould spur a humiliated United States to race for the moon.

"There were all kinds of wild fears that a man could lose his mind in zero gravity, lose his ability to make rational decisions," recalls Oleg Ivanovsky, who oversaw the construction and launch of the Vostok spacecraft that carried Gagarin. The flight was to be fully automatic, but what if weightlessness caused Gagarin to go mad and override the programmed controls? The engineers' solution was to add athree-digit security code that the cosmonaut would have to enter to gain command of the spacecraft. It proved unnecessary. The flightwent off safely, and the handsome Russian with the big smile became a poster boy for the communist world, still a national idol 43 years after his death in a jet training accident, and remembered with enormous affection by the last surviving pioneers of the Soviet space program at Star City outside Moscow, where he trained.
