On April 12, 1961, an almost unknown 27-year-old became the most famous man on the planet. Yuri Gagarin, in an 108-minute orbital flight aboard the Vostok 1, became the first human into space. Today is the 50th anniversary of Gagarin's flight, and though the Soviets were very quickly outclassed in the space race, that accomplishment a half-century ago is one that will live forever in the minds of most space enthusiasts.
