Juno’s Exploration of Ganymede, Europa and Io

Juno mission was designed to study Jupiter. But, over time, the torque from the Sun and Jupiter’s oblateness rotated Juno’s orbit, allowing the investigation of Jupiter’s satellite system, which was the primary objective of Juno’s extended mission. The Juno spacecraft performed close and distant flybys of Ganymede, Europa, and Io between 2021 and 2024. The data collected during these flybys provided unprecedented views of these Jovian moons. In this talk, I will focus on Juno’s multi-instrument view into the internal structure of Jovian moons using microwave radiometry, gravitational sounding and high-resolution imagery from Juno. I will describe how these datasets allow drawing comparisons between surface and subsurface properties of Ganymede, Europa and Io. Finally, I will outline how the new Juno data can help analyze and interpret the data from future Europa Clipper and JUICE missions.
