It was taken up in 2001 by Space Shuttle Discovery", mission STS-105. They also have a keyboard, a saxophone, a flute and a didgeridoo up there.,(reply>), iirc there's actually two guitars ! And they're slightly smaller than normal guitars, can't remember why exactly. Prob just to get them as light as possible while still making normal-ish playing possible. They're also decked in velcro so you can just press one against a wall to stay there !,(reply>), @Hana M. To communicate with space faring dinosaurs, of course.,(reply>), Didgeridoo? What do you want to use didgeridoo in space for?,(reply>), Pid The saxophone arrived in February, just in time for Thomas Pesquet's birthday, and I assume it's either already back on earth or will return with the next Dragon or Soyuz.
