The first human spacewalk that changed the world of cosmonautics forever

On April 12, our country and other former Soviet republics celebrate Cosmonautics Day. The holiday is dedicated to historical an event that took place on April 12, 1961. It was on this day that Soviet test pilot Yuri Alekseyevich Gagarin became the first person to cross the conventional boundary of space and make one orbit around the Earth, observing the surface of our planet from the porthole of the legendary Vostok spacecraft.
The above-mentioned flight lasted 1 hour and 48 minutes. During the entire time in orbit, Gagarin maintained radio contact with Earth.
Of course, this was an epochal event for all of humanity. Meanwhile, four years later something happened that changed world cosmonautics forever.
On March 18, 1965, Soviet cosmonaut Alexei Arkhipovich Leonov became the first person in history to walk in outer space. This daring experiment was a milestone in the space race and proved that humans could work outside of a spacecraft, opening up new possibilities for future missions.
Let us recall that the flight of the Voskhod-2 spacecraft with Pavel Belyaev and Alexei Leonov on board was part of the Soviet space program aimed at outstripping the United States in mastering extravehicular activity. The design of the spacecraft included an inflatable airlock called the Volga, through which Leonov was to enter space.
It is worth noting that despite careful training, real conditions turned out to be more difficult than expected. In outer space, Leonov's spacesuit swelled due to excess pressure, which made it difficult to return to the ship. The cosmonaut had to release some of the air and squeeze back into the airlock at the risk of his life.
Meanwhile, the two-time Hero of the Soviet Union spent 12 minutes and 9 seconds outside the ship, proving that a person can perform tasks in vacuum and zero gravity conditions.
At the same time, the return to Earth also turned out to be difficult: due to a failure of the automatics, Belyaev had to manually land the ship in the deep taiga, where the cosmonauts waited for rescuers for two days.
The first human spacewalk proved the feasibility of extravehicular activity, which became a key element in building orbital stations and repairing satellites in orbit. Spacewalks are now standard procedure, but it was Leonov's risky experiment that paved the way for these achievements.
This feat not only strengthened the USSR's position in the space race, but also showed that even in extreme conditions, human intelligence and courage are capable of overcoming any obstacles.
