First U.S. space flight

In 1961, America's first astronaut in space, Alan Bartlett Shepherd, Jr., made a 15 minute sub-orbital flight that reached an altitude of 115 miles, during which he experienced about five minutes of "weightlessness." He was launched in the 2,000-lb. capsule Freedom 7 from Cape Canaveral, Florida, by a Mercury-Redstone 3 rocket. The flight travelled 302 miles at a speed relative to the ground of of 4,500 mph. Although Shepard thus became the first American in space, the world's first human in space flight was Yuri Gagarin, a Russian cosmonaut, launched into orbit less than one month earlier, on 12 Apr 1961.
