Chris Hadfield. He is an educator in the truest sense of the word. During his time on the International Space Station, Hadfield went out of the way to engage the public. He showed us what happens when you cry in space, how difficult it is to ring out a washcloth (and get it wet to begin with), how awkward it is to get sick in space, and the various difficulties that arise what you are forced to use the bathroom without gravity. More than that, he showed us our world anew. Here is one of his most iconic performances from his time on the ISS.
