Vostok 1 with Gagarin on board blasts off on April 12, 1961.

The charred descent capsule of Vostok 1 is seen at the landing site, 700 kilometers southeast of Moscow, on April 12, 1961. The capsule landed empty as Gagarin made a parachute jump at an altitude of 7,000 meters.

Gagarin's feat made international headlines, even all the way in Huntsville, Alabama.

Gagarin is congratulated after the successful flight.

Upon returning to Earth, Gagarin was awarded the title Hero of the Soviet Union and became an essential part of global history.

In 2016, an installation featuring Gagarin's famous quote of “Let’s go!” during liftoff was constructed in Gorky Park in Moscow.

To commemorate the 55th anniversary of the first manned space flight, Russian activists Aleksei Busarov and Oleg Butsky drew a huge portrait of Gagarin on the ice of a frozen lake. To do that, they used satellite navigation equipment and spades.

In 2015, Cosmonautics Day coincided with the Orthodox Easter. A Perm-based artist, Aleksandr Zhunev, depicted Gagarin crucified to mark the coincidence. He explained this gesture by saying that science and religion had been in opposition to each other, but now science had started to lose out in public opinion.
