The entertainment world was shattered when it was announced that David Bowie passed away at the age of 69 after an 18-month battle with liver cancer.
Since the news broke, the Internet has been flooded with tributes from artists and fans about the incredible legacy that Bowie leaves behind. Of course, the most incredible tribute to Bowie didn't come out after his death.
In 2013, Commander Chris Hadfield uploaded his cover Bowie's 1969 hit "Space Oddity," bringing something to the song that nobody else possibly could: it was actually recorded onboard the International Space Station.
Hadfield updated the lyrics to reflect his time in space as he was about to hand over control of the ISS before his descent back to Earth. While the song already features haunting lyrics about the adventure of space exploration, very few actually understand the sensation as Hadfield does. His perspective gives the song an incredible new meaning.
Hadfield was originally given the rights to post his cover on YouTube for only a year because of the tricky international copyright laws. Though it came down for a short time after the end of that year, Hadfield was able to work out another agreement and the video has been given permission to be posted for another two years.
The day after the initial release, Bowie took to Facebook to share Hadfield's work, calling it "the most poignant version of the song ever created."
This isn't the first time Bowie has been honored by the scientific community. An endangered yellow spider was named Heteropoda davidbowie in 2009.
After listening to Hadfield's version, which is the best cover on that song that could ever possibly be done, take a little time to check out Bowie's original.
Rest in peace, Ziggy Stardust.
