If you haven’t followed Canadian Astronaut Chris Hadfield–the first Canadian commander of the International Space Station and “the most social-media savvy” astronaut in space–you should, at a bare minimum, at least see his farewell song at the end of his mission, revising David Bowie’s famous song, Space Oddity.

This one is a must.

Hadfield’s ISS Mission ran from December 19, 2012 to May 12, 2013. He is presently rehabilitating from the extended stay in microgravity. Hadfield is the recipient of numerous awards and special honors, including appointment to the Order of Ontario in 1996, receipt of the Meritorious Service Cross and Vanier Award in 2001, the NASA Exceptional Service Medal in 2002, and the Queen’s Golden Jubilee Medal in 2003.

Hadfield is working on the first original music album to be recorded in orbit. The first song recorded in space, Jewel in the Night, was released via YouTube on Christmas Eve 2012.
