NASA introduces audio of how Jupiter’s Ganymede moon sounds – nach Welt

Left to Right: The mosaic and geological maps of Jupiter's moon Ganymede have been compiled and contain the best images available from NASA's Voyager 1 and 2 spacecraft and NASA's Galileo spacecraft.

Introduce Ganymed, Jupiter’s icy moon and the largest moon in our solar system, can be a real challenge. (I’m still on, “Whoa, that’s a big moon.”) Getting it is a whole different story, and scientists are still working on it. Whether you want to learn more about the gigantic moon or unravel its scientific mystery, you now “hear” what Ganymede sounds like in space.

NASA’s Jet Propulsion Laboratory announced the 50 second audio trackwhich you can listen to below, created with data received by the Juno spacecraft during its Close flyby by Ganymede on June 7th. The dates for the inclusion were with Junos waves Instrument that measures electrical and magnetic waves generated in the magnetosphere of Jupiter. NASA then proceeded to shift the frequency of the emissions it collected into the audio range to create the audio track.

Scott Bolton, a senior researcher on the Juno Mission from the Southwest Research Institute in San Antonio, presented the recording at the American Geophysical Union’s fall meeting. The one launched in 2011 Juno-Mission aims to improve our understanding of the formation and role of giant planets They played in the creation of the solar system.

“This soundtrack is just wild enough to make you feel like you’re riding with Juno sailing past Ganymede for the first time in more than two decades,” Bolton said in a NASA news article. “If you listen carefully, you can hear the abrupt shift to higher frequencies around the center of the recording, which represents the entry into another region of Ganymede’s magnetosphere.”

This image of Jupiter's moon Ganymede was captured by the JunoCam imager aboard NASA's Juno spacecraft during its flyby of the icy moon on June 7, 2021.

Juno’s flyby of Ganymede occurred on its 34th trip around Jupiter and was the closest a spacecraft has ever gotten to the Solar System’s largest moon, which is bigger than the planet Mercury, since the Galileo spacecraft’s approach in 2000.

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