This file photo taken on April 12, 1961 shows the Soviet Vostok-1 spaceship with cosmonaut Yuri Gagarin on board blasts off on top of Rocket R-7 for the first manned trip into space from the Baikonur Cosmodrome in Kazakhstan. The 27-year-old's 108-minute flight is still remembered in Russia even after the USSR's collapse as its greatest national achievement. The first manned spaceflight allowed the Soviet leadership, fully entrenched in the cold war, to maintain the superiority of the communist system over their principal adversary, the United States.
