In February 1962, the space race between the United States and the Soviet Union was in full swing. Both nations had developed spacecraft to send humans into space and selected a group of pilots to fly those spacecraft.
The Soviets leaped ahead by placing the first man, Yuri A. Gagarin, in space on April 12, 1961, on a one-orbit flight around the Earth aboard his Vostok spaceship. The United States responded with two suborbital piloted Mercury missions, launched atop Redstone rockets.
The Soviets next kept a cosmonaut in space for a full day. On February 20, 1962, astronaut John H. Glenn became the first American to orbit the Earth during the three-orbit Mercury-Atlas 6 mission, aboard the spacecraft he named Friendship 7.
