The name of the first manned spaceflight is Vostok 1. This historic mission was launched by the Soviet Union on April 12, 1961, carrying cosmonaut Yuri Gagarin. Gagarin's flight lasted about 108 minutes, during which he completed one orbit around the Earth, becoming the first human to do so. The success of Vostok 1 marked a significant milestone in human space exploration, demonstrating that it was possible for humans to travel in space and return safely. This event also intensified the space race between the United States and the Soviet Union during the Cold War.
