On today’s episode of Modern Notion Daily, we welcome guest Col. Chris Hadfield, a retired Canadian astronaut. Hadfield was the first Canadian to walk in space and the first Canadian to act as commander of the International Space Station. He talks about how he became an astronaut, the life lessons he’s learned in space, and why the public outreach he does is so important. We also hear about his book, An Astronaut’s Guide to Life on Earth, which came out in paperback in April from Back Bay Books.
