Chris Hadfield was the first Canadian to walk in space and the first to command the ISS. He even lived underwater for two weeks, suggesting he might have a personal vendetta against breathable air. But despite his impressive cosmic CV, what really launched him into pop-culture orbit was his MTV Unplugged: ISS Edition.

Floating in his tin can in 2013, Hadfield picked up a guitar and covered David Bowie’s Space Oddity, while actually being in space, making every Earth-bound cover instantly obsolete. There he was, drifting weightless, singing "planet Earth is blue and there’s nothing I can do," while Earth spun below like a fragile little marble. The sheer commitment to the bit is staggering. Bowie himself even called it “possibly the most poignant version ever,” which is basically saint-level approval.
