Kjell Lindgren sent a video down to his home planet of him playing "Amazing Grace" on the bagpipes. He chose the song in tribute to researcher Victor Hurst, who was involved in his astronaut training and died suddenly in October. Lindgren, who was born in Taiwan and grew up in the U.S. and England, has been on the I.S.S. since July.
These aren't just any bagpipes, though. The BBC reports that Lindgren wanted to be able to play in space so badly that he asked McCallum Bagpipes about logistics two years before he took off. They made him a special, lighter set of bagpipes that would be easier to play and keep clean in space.
Lindgren is only the latest addition to the space man band, however. Perhaps the most famous musical astronaut is Chris Hadfield, whose out-of-this-world cover of David Bowie's "Space Oddity" has been viewed more than 27 million times on YouTube. Hadfield released an album of songs recorded in space earlier this year.
