Scientists from NASA’s Juno mission to Jupiter and its moons provided an audio track of Ganymede’s flyby at the fall meeting of the American Geophysical Union (AGU).
The 50-second sequence was generated from data collected during a flyby of Ganymede on June 7, 2021. The Juno Wave Instrument, which tunes the electric and radio-magnetic waves produced in Jupiter’s magnetosphere, collected data about those emissions on Ganymede. Its frequency was then shifted to the audio range to make the track audible.
“This soundtrack is wild enough to make you feel like you’re riding as Juno sails alongside Ganymede for the first time in more than two decades,” Scott Bolton, a mission scientist at the Southwest Research Institute, said in a statement.
“If you listen carefully, you can hear the sudden shift at higher frequencies around the midpoint of the recording, which is the entrance to a different region in the Ganymede magnetosphere.”
Detailed analysis and modeling of this data is underway. said William Court of the University of Iowa in Iowa City, a research associate principal investigator.
At the time of Juno’s closest approach to Ganymede, during the mission’s 34th flight around Jupiter, the spacecraft was only 1,038 kilometers from the surface of the Moon and was traveling at a relative speed of 67,000 kilometers per hour.
