The Gas Giants as Unique Laboratories for Space Plasma Processes 

Ali Sulaiman

Jupiter and Saturn’s internal magnetic fields carve out a cavity in the interplanetary medium to form two of the largest magnetospheres in our solar system. Embedded within are geologically active moons continuously loading plasmas into their magnetospheres: Io’s volcanoes at Jupiter and Enceladus’ geysers at Saturn. These internally sourced plasmas interact with the surrounding planetary magnetic fields, giving rise to mechanisms that ultimately shape the magnetospheres’ structures and drive their dynamics. Furthermore, our evolving understanding of Saturn’s rings is revealing their influence in this context as well. In 2016, NASA’s Juno spacecraft undertook the first polar orbits of Jupiter, and in 2017, NASA/ESA’s Cassini spacecraft performed its final orbits, which were highly inclined and adjusted to pass through the gap between Saturn’s atmosphere and innermost ring - both providing unprecedented coverage and proximity to their planets. These highly inclined, proximal orbits enable the spacecraft to directly sample the ionospheres and traverse magnetic field lines threading the auroral regions, as well as those connecting the planets to their active moons and ring system (for Saturn). Such measurements are essential to establishing how these planetary systems operate on a global scale, as well as understanding the fundamentals of space plasma processes in a parameter space vastly different from the near-Earth and inner heliosphere environment. I will highlight recent observations that provide a new view of the gas giants and underline them, to our current understanding, as the most dynamic and diverse environments in our solar system.
