Jupiter’s moon Europa is of high scientific interest because it is an ocean world with a tenuous atmosphere and may also harbor sporadic water plumes. Europa is also embedded deep within Jupiter’s magnetosphere and resides in a harsh environment of radiation comprised of energetic-to-relativistic electrons and ions. Understanding the interplay between Europa and its near-space environment is key to unlocking the mysteries on how energetic particles contribute to surface weathering processes and how the moon itself and the neutral gasses that surround its orbital region contribute to energetic charged particle dynamics (e.g., acceleration and losses). In this presentation, we report on energetic particle observations made by Juno/JEDI during the PJ45 close flyby of Europa and discuss implications for the Particle Environment Package (PEP) instrument suite onboard ESA’s JUICE mission.
