The Juno spacecraft soon observed storms for Jupiter and “heard” the moon of Jupiter Ganymede – listen to the dramatic flight near the ice moon

A dramatic ride with an audio strip collected during a flight near Ganymede on a justice mission – one of the highlights that the mission scientists shared in a review at the fall meeting of the American Geophysical Association

Voices Flight near Ganymede, magnetic fields and excellent comparisons between the oceans and atmospheres of Jupiter and Earth were discussed in a review of NASA’s Juno mission to Jupiter at the fall meeting of the American Geophysical Association in New Orleans.

The researcher Juno Scott Bolton’s Chief of San Antonio’s Southwestern Research Institute first presented a 50-second audio strip generated from data collected during the mission’s flight close to Jupiter Ganymede’s moon on June 7, 2021. Juno’s wave device, tuned to electric and magnetic radio waves Formed in the magnetosphere of Jupiter, collected the data on these emissions Their der was transferred to the audio field to create the audio track.

“This soundtrack is so wild that you feel like you’re inside Juno as it cruises and passes Ganymede for the first time in more than two decades.” Said Bolton. “If one listens carefully, one can hear the sudden change to higher frequencies around the midpoint of the recording, which represents an entry into a different region in Ganymede’s magnetosphere.”

The detailed analysis and modeling of the wave data continues. “It is possible that the change in frequency shortly after the closest approach is due to a transition from the night side to the day of Ganymede,” said William Corrett of the University of Iowa in Iowa City, a co-principal researcher in wave research.

in time Juno’s closest approach to Ganymede – on the 34th flight of the mission around Jupiter – the spacecraft was 1,038 km from the moon and moving at a relative speed of 67,000 km / h.

Jack Connerney of NASA’s Goddard Space Flight Center in Greenblatt, Maryland is Juno’s chief magnetometer researcher and the mission’s deputy chief investigator. Produced the most detailed map ever obtained of Jupiter’s magnetic field.

The map created from data collected from 32 laps in Juno’s main mission provides new insights into the mysterious big blue dot of The gas giant, a magnetic anomaly in the star’s equator Juno’s point out that there has been a change in the gas giant’s magnetic field during the five years the spacecraft has been in orbit, and the large blue dot moves east at a speed of about 4 cm per second relative to the rest of Jupiter’s interior, orbiting the star every 350 years or so. .
