Yuri Gagarin — First Human in Space

On April 12, 1961, Soviet cosmonaut Yuri Alekseyevich Gagarin, a 27-year-old former foundry worker and fighter pilot, became the first human being to travel to outer space. Aboard the Vostok 1 spacecraft, Gagarin completed a single orbit of the Earth in 108 minutes, reaching a maximum altitude of 327 km. As the rocket launched, he exclaimed "Poyekhali!" ("Let's go!"). The flight was entirely automated — Soviet engineers were unsure how weightlessness would affect human cognition — though Gagarin carried a sealed envelope with a manual override code. He ejected from the capsule at 7 km altitude and parachuted to a field near the Volga River, where he was met by a bewildered farmer and her daughter. Gagarin became an instant global celebrity and a symbol of Soviet technological achievement.
