Canadian astronaut Chris Hadfields rendition of \Space Oddity,\ an astronomically popular music video shot in the International Space Station, is going offline today. According to a tweet by Hadfield, the song was posted under a year-long license from David Bowies publishers, and it expires today. During his stay in space, Hadfield was interviewed by William Shatner and participated in a highly publicized NASA hangout; he finally resigned from the Canadian Space Agency in June of 2013 after a decades-long career. Bowies last day – we had permission for a year, so our Space Oddity video comes down today.
