NASA introduces audio of what Jupiter’s Ganymede moon sounds like

imagine GanymedeJupiter’s icy moon and the largest moon in our solar system, can be challenging. (I’m still going, “Hey, that’s a big moon.”) Understanding it is a whole different story, and scientists are still working on that. Whether you want to learn more about the giant moon or unravel its scientific mysteries, you’re now “listening” to what Ganymede sounds like in space.

NASA’s Jet Propulsion Laboratory has the 50 seconds audio track, which you can listen to below, created with data captured by the Juno spacecraft during its fly close of Ganymede on June 7. Data for the recording was collected with Juno’s Waves instrument, which measures electrical and magnetic waves produced in Jupiter’s magnetosphere. NASA then proceeded to shift the frequency of the collected emissions to the audio range to create the audio track.

Scott Bolton, principal investigator of the Juno mission at the Southwest Research Institute in San Antonio, presented the recording at the fall meeting of the American Geophysical Union. Launched in 2011, the Juno Mission aims to increase our understanding of the formation of giant planets and the role they played in the formation of the solar system.

“This soundtrack is just wild enough to make you feel like you’re riding along as Juno sails past Ganymede for the first time in more than two decades,” Bolton said in a comment.

Juno’s flyby of Ganymede took place on its 34th trip around Jupiter and was the closest a spacecraft has ever come to the solar system’s largest moon, larger than the planet Mercury, since the Galileo spacecraft’s approach in 2000.

The spacecraft managed to come within 645 miles (1,038 kilometers) of Ganymede’s surface while traveling at 41,600 mph (67,000 kph).
