April 12 is one of the most significant anniversaries in the history of space exploration. In 1961, the Soviet Union launched the first man into space, cosmonaut Yuri Gagarin, aboard Vostok 1 (left). Exactly two decades later, the United States launched its first space shuttle, Columbia, with astronauts John Young and Robert Crippen at the controls.
