Juno Results: Ganymede, Europa, Io, and Jupiter’s Rings

Session ID#: 159438

Session Description:
Juno’s Extended Mission began last summer and transforms the Jupiter-focused mission to a full system explorer. The Extended Mission runs through 2025 and includes numerous close and distant flybys of Io, Europa, and Ganymede along with an exploration of Jupiter’s poorly understood ring system. The first Ganymede close flyby (mid-summer 2021) included a radio occultation, in-situ observations of Ganymede’s magnetosphere and its interaction with Jupiter, survey of its near-surface ice crust and spectacular high-resolution imagery of the surface geology and composition.

The first Europa close flyby (September 2022) will bring Juno to ~350 km from the surface of the ocean world and shed light on Europa’s ice crust/surface, atmosphere, subsurface ocean, and localized environmental indicators of putative plume activity. Europa’s near-space environment in the context of space weathering effects and interaction with the Jovian magnetosphere will also be an area of focus.

Two close flybys of Io will occur towards the end of the Extended Mission. Distant observations of Io have already begun from < 100,000 km to investigate spatio-temporal variability of its volcanic features.

This session welcomes observations and models related to Juno’s observations of Ganymede, Europa, Io, and Jupiter’s rings obtained during Juno’s Prime and Extended Missions. Look-forward studies related to the full Juno Extended Mission’s observations of the Galilean satellites and rings are also welcome.
