Adam Savage of Mythbusters has made it a tradition to walk the floors of Comic Con without being recognized due to an awesome costume. He wore a spacesuit last year. This year, he takes it up a notch by wearing a spacesuit from the 1969 movie 2001: A Space Odyssey, taking astronaut Chris Hadfield with him.
The Comic Con walk begins at about ten minutes in, but if you watch the whole thing, you’ll learn a lot about space suits from both Savage and the man whose life depended on one. But the Stanley Kubrick version is still something new to Hadfield. An apt comment:
Real astronaut dresses as fake astronaut so nobody will know he's an astronaut...
-Thanks, Daniel Portolan!
Savage is a super-fan of Andy Weir's (who shows up at 11:34) book The Martian; soon to be on the Silver Screen. While it's essentially a disaster story, it's hard science fiction which is based on science reality.
