One year ago, Astronaut Chris Hadfield posted his cover of David Bowie's "Space Oddity" to Youtube. It is amazing and if you haven't watched it yet, you should. But quickly. That's because, as Hadfield announced on Google Plus, he only had permission to use the song for one year, which means he will be taking down his cover at the end of the day today, May 13. "Bowie's last day," Hadfield wrote, adding, "We had permission for a year, so our Space Oddity video comes down today. One last look." 

The one-year deal was negotiated before Hadfield released the recording, a process that took several months and involved Bowie's representatives, NASA, Russia's space agency ROSCOSMOS and the Canadian Space Agency, who employed Hadfield. In just one year, the video generated over 22 million hits, which will make perfect sense to anyone who's seen it. Although we're sure the video will pop up here and there in the future, because this is the internet, the video will come down from its official home at the end of the day when the agreement ends. 

Hadfield posted the video just as his tenure aboard the International Space Station ended in May of 2013. During his 146 days in orbit, Hadfield prolifically tweeted from the ISS and aimed to complete the first album ever recorded in space. The Canadian retired from the CSA shortly after returning from this mission, making his cover of "Space Oddity" particularly poignant. 

At least he's still making Youtubes, though:
