I first put this post up at Scientific American on May 12, 2013
Colonel Chris Hadfield is a Canadian astronaut, a former mission specialist on STS-74 who also performed multiple EVAs on STS-100, and, for a few hours longer, the well-loved commander of the International Space Station mission 35.
He has been a great inspiration for space travel via every type of social media (with the assistance of his son, Evan), giving those of us down on Earth some of the best peeks at what it is like to live and work in space, plus has entertained us with his guitar playing as well! He tweets constantly, sharing photos of his view from above and has made nearly 70 informative videos to quench our curiosity about day to day space living. He has captured our imagination for space travel again!
