1965: On 18 March 1965, the first spacewalk took place.
Voskhod 2 launched into space carrying Aleksey Leonov and Pavel Belyayev aboard. On the second orbit Leonov left the spacecraft through the air lock while still tethered to the vessel. He was the first person to climb out of a spacecraft in space. While outside, he took motion pictures and practiced moving outside of the spacecraft for 10 minutes.
