Imagining Ganymede, Jupiter’s ice moon and the largest moon in our solar system, can be a real challenge. (I’m still thinking, “Wow, that’s a big moon.”) Understanding this is a whole other story, and scientists are still working on it. Whether you want to know more about a giant moon or expose its science mystery, you are now “listening” to how Ganymede sounds in space.
NASA’s Jet Propulsion Laboratory announced on Friday 50-second audio recording, which you can listen to below, created from data recorded by the Juno spacecraft during its close flyby Ganymede June 7th. Data for the recording was collected from Juno’s Waves instrument, which measures the produced electric and magnetic waves in Jupiter’s magnetosphere. NASA then proceeded to shift the frequency of collected emissions to the audio range to make an audio recording.
Scott Bolton, chief researcher on the Juno mission from the Southwest Research Institute in San Antonio, presented the footage at the fall meeting of the American Geophysical Union. Launched in 2011, the Juno mission it aims to improve our understanding of how giant planets form and their role they played in creation Of the solar system.
“This soundtrack is wild enough to make you feel like you’re driving while Juno is sailing past Ganymede for the first time in more than two decades,” Bolton said in NASA newspaper article. “If you listen carefully, you can hear a sudden change in higher frequencies around the middle of the recording, which is an entry into another region in Ganymede’s magnetosphere.”
Juno’s flight of Ganymede took place on her 34th orbit around Jupiter and was the closest the spacecraft ever reached the largest moon in the solar system, which is larger than the planet Mercury, since the approach of the Galileo spacecraft in 2000.
The spacecraft managed to reach 1038 kilometers from Ganymede’s surface while traveling at a speed of 41,600 mph (67,000 km / h).
