Chris Hadfield’s mission aboard the International Space Station comes to an end tomorrow. His five months out in space has really seen something like a revolution in the communication between the people of Earth and denizens of outer space thanks to social media. Using Twitter, YouTube and video links, Hadfield has brought us a little insight into our world and space while cementing himself as a Canadian national treasure.

In addition to Hadfield’s personal reflections, the Centre of Geographic Sciences has compiled an interactive map of Hadfield’s many spectacular photos of Earth from space. You can (and should) check it out here.
