Yuri Gagarin

Yuri Alekseyevich Gagarin became the first man to enter deep space on April 12, 1961, when the Soviet cosmonaut made a flight that orbited Earth lasting one hour and 48 minutes in his Vostok 1 spacecraft. This accomplishment made the smiling Soviet pilot internationally famous as the first man to venture into space, the final frontier. The feat beat the Americans, who put Alan Shepherd into space in a sub-orbital flight on May 5, 1961, and did not have an astronaut orbit the earth until John Glenn accomplished the feat on February 20, 1962. The perpetually smiling Gagarin, who was promoted from senior lieutenant to major in the Soviet Air Force and was awarded the honor Hero of the Soviet Union for his accomplishment, became an international celebrity.
