If you've been in the United States (and maybe other places) lately, you've heard of astronaut Chris Hadfield. He retired in July after
an illustrious career, but he's written a book that is getting raves:
An Astronaut's Guide to Life on Earth: What Going to Space Taught Me About Ingenuity, Determination and Being Prepared for Anything
He has also given numerous interviews, including
this one on NPR. But what has caught the attention of even more people of late is the fact that when he was on the International Space Station during his last mission there earlier this year, he recorded a YouTube video of David Bowie's
Space Oddity. At the moment it has more than 18 million views.
