Gagarin 50

on 12 April 2011

Vostok 1 was the first spaceflight of the Vostok program and the first human spaceflight in history. 3KA Vostok spacecraft was launched on 12 April 1961 and it took to space Yuri Gagarin, a cosmonaut from the Soviet Union. This flight marked the first entrance of a man in outer space and the first orbital flight of a manned vehicle. Vostok 1 was launched by the Soviet space program and was designed by Soviet engineers, coordinated by Sergey Korolyov.

The spaceflight consisted in orbiting the Earth once. According to official reports, the flight lasted 108 minutes from launch to landing. As planned, Gagarin landed separately from his ship after it was dropped from a height of 7 km above the Earth.

This event is celebrated every year on 12 april, by organising an event called "Yuri's Night".
