Astronauts Love to Rock it Out in Space

To give you some context, the first ISS segment was launched into orbit Nov. 20, 1998. For almost as long as there's been an International Space Station, there have been astronauts playing music onboard.

There was historical precedent. Gemini astronauts Walter Schirra and Thomas Stafford famously played "Jingle Bells" in space Dec. 15, 1965, using some bells and a harmonica they'd taken along for the trip.

Musical instruments have, from the very beginning, served as ISS morale-boosters as well.

Before NASA's Carl Walz made his debut on the station in 2001, he said it'd be nice to take a keyboard up there. He got his wish, but certain adjustments had to be made. Whenever Walz played his keys, he kept himself grounded with foot restraints. Also, he'd wind a bungee cord around his legs to hold the instrument in place.

Fellow ISS alum Cady Coleman arrived on the vessel for a 2011 mission with a penny whistle and three flutes in tow. One was temporarily lost when an alarm sounded, forcing Coleman to release the instrument midsong. (Don't worry, she had an easy time finding it later.)

"I very much like to play music with other people and I didn't happen to get assigned to a crew where anybody else really played music," Coleman told MIT in 2014.

However, she got to join Jethro Tull's Ian Anderson for a "Space-Earth Duet" during the spring of 2011. Each musician played a segment of Bach's "Bourrée in E Minor." Anderson recorded his performance in Russia; Coleman filmed hers in low-Earth orbit. Footage from both was later combined and posted online.

Besides the instruments we've already mentioned, ISS astronauts have made music with saxophones, bagpipes and even a didgeridoo during their flights.

Of course, safety is a top priority at NASA and aboard the International Space Station. Beneficial as they are from a mental health perspective, instruments can't be allowed to put a crew's well-being at risk.

"We test some of them by putting a piece of the material into a closed chamber and heating it to as much as 120 degrees [49 degrees Celsius] for three days," NASA space station manager Mike Pedley said in a 2003 interview. Such tests can reveal a lot about potential safety hazards.

One component that has to be examined is the alcohol instrument manufacturers often use as a cleaning solvent. "Something like benzene... is relatively toxic, and it would only take a small amount to make the hardware unacceptable," Pedley noted.

That's why the guitar Hatfield played was built with nonflammable material and lacked benzene altogether.

Now we're just guessing here, but since nobody likes floating debris in their workspace, Pete Townshend-style guitar smashing is probably a big no-no on the ISS. Save that stuff for Earth.
