About Chris Hadfield
Every day aboard the International Space Station, Chris Hadfield would tweet "Good morning, Earth." In his five months on the ISS — three as commander — Hadfield used social media to bring back a sense of wonder about space, including posting a cover of David Bowie's "Space Oddity." Hadfield is also the author of the recent book, An Astronaut's Guide to Life on Earth.
