History of Cosmonautics Day

On April 12, 1961, the Soviet Union made history by being the first country to send a crewed flight to space. Aboard the Vostok 1 spacecraft, cosmonaut Yuri Alekseyevich Gagarin became the first man to orbit the planet, spending 108 minutes in outer space. This achievement opened up a new era in space exploration and was seen as a triumph for the Soviet space program. The only words attributed to Gagarin during the flight were: “Flight is proceeding normally; I am well.” After his historic flight, Gagarin was exalted to the status of a celebrity and hero.Major newspapers worldwide published his biography and other details of his flight. After being escorted to the Kremlin in a motorcade of high-ranking officials, he was awarded the title of ‘Hero of the Soviet Union’ by Nikita Khrushchev, the highest Soviet honor that could be achieved. Other awards presented to him included the ‘Order of Lenin,’ ‘Merited Master of Sports of the Soviet Union,’ ‘Hero of Socialist Labor in Czechoslovakia,’ the ‘Konstantin Tsiolkovsky Gold Medal,’ and ‘Pilot-Cosmonaut of the U.S.S.R.’ On April 9, 1962, Cosmonautics Day was established by the Soviet Union. After becoming a deputy to the Soviet Union in 1962, he was promoted to the rank of colonel of the Soviet Armed Forces on November 6, 1963. On April 7, 2011, to mark the 50th anniversary of the monumental flight, the United Nations General Assembly declared April 12 as the International Day of Human Space Flight.
