On April 12, 1961, man first conquered space. For the first time in the world, the Soviet spacecraft "Vostok" with the pilot-cosmonaut Yuri Alekseevich Gagarin on board was launched from the Baikonur cosmodrome. This flight was a world-class historical event and not everything was smooth and easy. I suggest reading interesting facts about the first manned flight into space:
The first flight into space was being prepared in a hurry, as intelligence reported that the Americans were planning to launch the spacecraft by the end of April. The leadership of the USSR could not allow this and gave the command to get ahead of the Americans in any way.
One of the key parameters in the selection of the first cosmonaut was a height of no more than 170 cm and a weight of no more than 70-72 kg. Requirements for height and weight have arisen due to technical limitations on the Vostok spacecraft.
It is interesting that three reports about Gagarin's flight into space were previously prepared. The first is "Successful", the second with a request for help in the search if he falls on the territory of another country or in the world's oceans, and the third is "Tragic" if Gagarin dies.
Before the flight, they did not know how the human psyche would behave in space, so special protection was provided against the control of the East in a fit of violence. To turn on manual control, Gagarin had to open a sealed envelope, inside which was a sheet with a code, by typing which on the control panel it would be possible to unlock it.
After completing one revolution around the Earth, at 10:55:34 at 108 minutes, the spacecraft completed its flight. Due to a failure in the braking system, the descent vehicle with Gagarin landed not in the planned area 110 km from Volgograd, but in the Saratov region, near the village of Smelovka.
Interesting fact, after the flight the First Cosmonaut Lieutenant Gagarin was promoted to Major. And the news broadcast about Major Gagarin, who conquered space, and April 12 became the international day of cosmonautics.
