NASA Debuts Audio of What Jupiter’s Ganymede Moon Sounds Like

Left to right: The mosaic and geologic maps of Jupiter’s moon Ganymede were assembled incorporating the best available imagery from NASA’s Voyager 1 and 2 spacecraft and NASA’s Galileo spacecraft.

Imagining Ganymede, Jupiter’s icy moon and the biggest moon in our Solar System, might be fairly the problem. (I’m nonetheless at, “Whoa, that’s a big moon.”) Understanding it’s a complete different story, and scientists are nonetheless engaged on that. Whether you’re searching for to study extra in regards to the gigantic moon or unravel its scientific mysteries, you now “listen” to what Ganymede seems like in area.

NASA’s Jet Propulsion Laboratory on Friday revealed the 50-second audio track, which you’ll be able to hearken to under, created with information captured by the Juno spacecraft throughout its shut flyby of Ganymede on June 7. Data for the recording was gathered 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 into the audio vary to make the audio observe.


Scott Bolton, a principal investigator on the Juno mission from the Southwest Research Institute in San Antonio, introduced the recording on the fall assembly of the American Geophysical Union. Launched in 2011, the Juno mission goals to advance our understanding of how large planets kind and the function they performed within the creation of the Solar System.

“This soundtrack is just wild enough to make you feel as if you were riding along as Juno sails past Ganymede for the first time in more than two decades,” Bolton stated in a NASA news article. “If you listen closely, you can hear the abrupt change to higher frequencies around the midpoint of the recording, which represents entry into a different region in Ganymede’s magnetosphere.”

This image of the Jovian moon Ganymede was obtained by the JunoCam imager aboard NASA’s Juno spacecraft during its June 7, 2021 flyby of the icy moon.

Juno’s flyby of Ganymede occurred on its thirty fourth journey round Jupiter and was the closest a spacecraft has ever gotten to the Solar System’s largest moon, which is greater than the planet Mercury, for the reason that Galileo spacecraft’s strategy in 2000.


The spacecraft managed to get inside 645 miles (1,038 kilometers) of Ganymede’s floor whereas touring at a velocity of 41,600 mph (67,000 kph).
