March 18th

On this day - March 18th 1965 - The first person to walk in space 

On March 16th left the Soviet cosmonaut Alexey Leonov his spacecraft for 12 minutts and 9 seconds for a walk in Space. He thereby became the first human to do Extravehicular activities, which is the official term for activities done in space outside of the spacecraft. Leonov was connected to the spacecraft with a long cable and pulling this cable was the only way he could control is motions while in space. In June the same year did the US their first spacewalk when Edward White left his spacecraft for 21 minutes. The first person to successfully stay outside of the spacecraft for longer periods was Edwin "Buzz" Aldrin who worked on the aircraft for over two hours in 1966.
