For six months, from December 2012 to May 2013, Canadian astronaut Chris Hadfield served as the commander of the International Space Station. Hadfield conducted a record-setting number of scientific experiments. He also gained a reputation as the "most social media savvy astronaut" by sharing his daily life, posting photos on Tumblr and Twitter and videos on YouTube.

A musician who's played guitar in space since his first mission in 1995, one of Hadfield's most memorable videos, with nearly 24 million views to date, was a cover of David Bowie's "Space Oddity." It was how he capped his time at the station, and according to NASA, it was the first music video created in space.

Hadfield spoke to Up to Date host Steve Kraske about what it's like in space, and his recent collection of photographs, You Are here: Around the World in 92 Minutes.
