Today is your last chance to watch the first music video shot in space, featuring Canadian astronaut Chris Hadfield.

Hadfield recorded a cover of David Bowie's Space Oddity while he was the first Canadian commander of the International Space Station last year. He headed back to Earth on May 13, 2013, and posted the video on YouTube as a goodbye tribute.

"We had permission for a year, so our Space Oddity video comes down today," Hadfield wrote in a comment on YouTube Tuesday morning.

At that point, the video had been viewed more than 22 million times.

Hadfield announced last June that he was retiring from his career as an astronaut.
