As Alison noted on Friday, Canadian astronaut Chris Hadfield is the world's best astronaut. His time in orbit has been spent doing all sorts of science-y space things, I'm sure, but he's also been making fantastic videos for all of us poor bastards who're trapped on Earth (not to mention doing things like discussing the intricacies of space travel with James T. Kirk). All this week, he's going to be talking about how our senses operate in space, and yes. He is the world's best astronaut.
Via @CanadianSpaceAgency, which, due to the fact that they have a Chris Hadfield and NASA does not, is currently kicking NASA's ass.
