NASA appears for the first time with the sound of Jupiter’s moon Ganymede

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

imagination Ganymede, the icy moon of Jupiter and the largest moon in our solar system, can be quite a challenge. (I keep saying, “Wow, that’s a big moon.”) Understanding this is another story and scientists are still working on it. Want to know more Detecting a huge moon or its world Riddle, now you “hear” what Ganymede looks like in space.

NASA’s Jet Propulsion Laboratory launched Friday 50 second audio track, which you can hear below, is made from data captured by the Juno spacecraft during its duration closed trip From Ganymede on June 7. Recording data was collected using Juno wave An instrument that measures electric and magnetic waves generated in the magnetosphere of Jupiter. Then NASA proceeded to transmit the frequency of the collected emissions into the soundband to create an audio clip.

Scott Bolton, senior researcher at the Juno Mission of the Southwest Research Institute in San Antonio, presented the recording at the fall meeting of the American Geophysical Union. It was launched in 2011, Messiah Juno Its goal is to improve our understanding of how planets form and their role played in space Solar System.

“This soundtrack is wild enough to make you feel like you’re riding when Juno first crossed Ganymede over two decades ago,” Bolton said in a statement. NASA news articles“If you listen carefully, you may hear a sudden change in high frequencies around the center of the recording, which represents Ganymede’s entry into another region of the magnetosphere.”

This image of the Jovian moon Ganymede was acquired by the JunoCam sensor aboard NASA's Juno spacecraft during the icy moon flight on June 7, 2021.

Juno’s circumnavigation of Ganymede occurred on its 34th voyage around Jupiter and was the closest spacecraft to the solar system’s largest moon, larger than Mercury, since the approach of the Galileo spacecraft in 2000.

At 41,600 mph (67,000 km/h), the spacecraft was able to reach within 645 miles (1,038 km) of Ganymede’s surface.
