Thousands of heartfelt tributes have been pouring in today in memory of transcendent rock legend David Bowie. Since news of his death broke, the likes of Madonna, the Rolling Stones, Paul McCartney and even Golden Globes host Ricky Gervais have paid their respects.
But one of the most powerful tributes that's been shared today actually dates back to 2013.
Canadian astronaut Chris Hadfield covered Bowie's "Space Oddity" while serving as commander aboard the International Space Station. His remains an incredible rendition of an iconic song and, in Bowie's own words, “possibly the most poignant version of the song ever created."
Hadfield posted a farewell message to Bowie on Twitter today, and his now-famous 2013 cover has appeared on a number of memorial pages.
