NASA celebrates 50-years of spacewalk – prepares for Mars mission

It was on 3 June 1965 that astronaut Edward Higgins White became the first American to step out into the void of space and, this week NASA is celebrating 50-years of spacewalk. He performed the feat during the second manned spaceflight in NASAs Project Gemini.
This has been reported in dailymail.co.uk dated 5 June 2015.

He did the spacewalk for more than 20 minutes as he maneuvered himself around the Gemini spacecraft while it travelled from over Hawaii to the Gulf of Mexico – his total orbital stroll was 6,500 miles long.
After that historic first, astronauts of NASA have carried out spacewalks, or extravehicular activity (EVA), on the Gemini, Apollo, Skylab, Space Shuttle and International Space Station programs. As per statistics, astronauts have explored the lunar surface, completed 82 spacewalks outside of the space shuttle, and 187 spacewalks outside the International Space Station.
Incidentally, spacewalks totaling a total of 166 hours were undertaken to service the Hubble Space Telescope. The existing spacesuits worn by astronauts are cumbersome and, since NASA has predicted that humanity could encounter extra-terrestrials within a decade, there would be a need to design more comfortable space suit.
