• On April 12, 1961, Soviet cosmonaut Yuri Gagarin became the first person in outer space. His ship, Vostok 1, made one orbit of Earth before re-entering the atmosphere. Unlike other spacecraft (including the Freedom 7, which took American astronaut Alan Shepherd into space a month later), Vostok 1 could not slow down when it re-entered Earth's atmosphere. This meant that Gagarin had to parachute out of his capsule about 2.5 kilometers (8,200 feet) in the air.
     
    Vostok 1 launched from the massive Baikonur Cosmodrome, part of the old Soviet Union. Now, the facility is part of Kazakhstan. Today, astonauts headed for the International Space Station still take off from Baikonur's "Gagarinsky Start"—Gagarin's launchpad.
