This. Is. So Cool. We think it's safe to say that this has hands down won the title of the Best Selfie of 2013. Mike Hopkins , a NASA astronaut, snapped the pic while on a mission with fellow astronaut, Rick Mastracchio, to change a faulty water pump on the outside of the International Space Station!
