the guitar on the ISS is actually communal, it stays there, Chris just used it,(reply>), @John McIntyre Imagine all the Wonderwall you're going to hear 😂,(reply>), Communal space guitar... I'd kill myself so fast haha,(reply>), @Michael Abbott Honestly I feel like once an instrument is on the ISS it would stay in tune better with all the environmental control they have, the trip up, on the other hand, must be brutal.,(reply>), It must get horribly out of tune,(reply>), On the other hand, Thomas Pesquet, who launches in mid-November this year, is planning to bring his saxophone (a soprano sax, naturally, for practical reasons) to the ISS. For all I know, it may have been sent with a supply spacecraft and already be there waiting for him.
