On 12 April 1961, at the controls of the spacecraft Vostok 1, Gagarin became the first man to orbit Earth, completing his mission in 108 minutes at a speed of 18,000 miles per hour. Soviet leader Nikita S. Khrushchev hailed Gagarin's accomplishment, which came just three and a half years after Sputnik 1, another triumph of the alleged superiority of socialism over capitalism. Gagarin's success was a major Soviet achievement and a key propaganda victory in the Cold War space race.
After his mission, Gagarin was promoted to the rank of major and was honored with the Hero of the Soviet Union Medal. From then on, he enjoyed a life of privilege but longed to return to space. In 1967 he commenced training for the Soyuz program. Gagarin was killed while piloting a MiG-15 fighter on the outskirts of Moscow on 27 March 1968 and was buried, alongside other prominent Soviet citizens, near the Kremlin Wall.
