Yuri Gagarin was born on March 9, 1934, in a town outside of Moscow, Russia.
After graduating from secondary school in 1949, Gagarin went to several technical schools before joining the Orenburg Higher Air Force School in 1955. He began his cosmonaut training in 1960, along with 19 other candidates.
On April 12, 1961 at 9:06 am, Gagarin lifted off in the Vostok 1 spacecraft and after a 108-minute flight, he parachuted safely to the ground in the Saratov region of the Soviet Union.
The first human to fly in space, he successfully completed one orbit around the Earth. After his historic flight, Gagarin became an international symbol for the Soviet space program and in 1963 was appointed deputy director of the Cosmonaut Training Center. In 1966 he served as a backup crewmember for Soyuz 1 and on February 17, 1968, he completed a graduate degree in technical sciences.
Gagarin died on March 27, 1968, when the MiG-15 he was piloting crashed during a training flight.
