It had to be quite the rush. The first spacewalk, or extravehicular activity (EVA) happened March 18, 1965, when cosmonaut Alexei Leonov first departed the Soviet Union's Voskhod 2 spacecraft to test the idea – he stayed out about 10 minutes. American Edward White II took the US’ first spacewalk that year in June stepping out of the Gemini IV spacecraft. Since that time many have taken the plunge outside the their spacecraft to fix problems, make adjustments and even hit a golf ball, as one NASA astronaut did in 2006 – he shanked it. Take a look at some of the milestones of spacewalking.
