First spacewalk in history happened 52 years ago
The first ever spacewalk was performed by Soviet cosmonaut Alexei Leonov on March 18, 1965. Leonov exited the Voskhod 2 spacecraft by climbing through a cylinder-like object and floated into open space for about 10 minutes. Interestingly, the Soviet spacewalk was made in anticipation of an American spacewalk, which was expected to be performed in June 1965.
