On October 11, 2019, the legend of Soviet cosmonautics, the first person in open space, Aleksei Leonov, passed away. In early 1960, Aleksei Leonov was recruited into the cosmonaut corps, referred to in documents as "Air Force Unit No. 1," alongside Yuri Gagarin and Gherman Titov. Out of 3,461 candidates, only twenty were selected! Later, three candidates were dismissed due to health issues, three for a drunken brawl with a military patrol, and one was expelled for immoral behavior and divorce. Valentin Bondarenko died during tests due to a fire in the isolation chamber. Aleksei Leonov was among the twelve lucky ones who passed all the tests. In 1965, during the flight of the "Voskhod-2" spacecraft, he made the first spacewalk in the history of cosmonautics, showing exceptional bravery, especially during an emergency when his inflated spacesuit hindered his return to the spacecraft. In Arthur Clarke's science fiction novel "2010: Odyssey Two" and its film adaptation "2010: The Year We Make Contact," the Soviet interplanetary spacecraft is named after cosmonaut Aleksei Leonov. Twice Hero of the Soviet Union, Major General of Aviation Aleksei Leonov was buried with military honors on October 15, 2019, at the Federal Military Memorial Cemetery in Mytishchi.
