Chris Hadfield is definitely the most charismatic astronaut in popular culture today. I’m not sure if that’s saying much, but the man is electric, doing science experiments over YouTube and actually getting people interested in outer space. He’s from the Canadian Space Agency, and he recently did an amazing cover of David Bowie’s Space Oddity, while literally floating through outer space (in the International Space Station). Its him playing and singing, and Chris, thank you for making space cool.
