Juno Witnesses Extreme Compression of Jupiter's Magnetosphere

R. J. Wilson, F. Bagenal, M. J. Brennan, J. E. Connerney et autres

Abstract In October 2024, the Juno spacecraft observed an extreme compression of Jupiter's magnetosphere. This event pushed the magnetosheath into an unprecedented distance of only 30 Jupiter radii from Jupiter. This suggests an enhanced Solar Wind (SW) dynamic pressure (DynP), that was …

The High Plasma Density Observed Along the PJ57 Juno Flyby of Io Implies the Presence of a Dense Atomic Corona

V. Dols, F. Bagenal

Abstract On December 2023, the Juno spacecraft made a flyby of Io above the northern hemisphere at a closest approach (CA) altitude of ∼1,500 km (PJ57). The Juno/Waves and Radio‐occultation measurements showed a surprising large electron density ∼28,000 cm −3 near closest …

Atmospheric Mass Flux as a Function of Ionospheric Emission on Unmagnetized Earth

P. C. Hinton, D. A. Brain, N. R. Schnepf, R. Jarvinen et autres

We explore ion escape from, and solar ion deposition to, \hll{an unmagnetized Earth-like planet}. We use RHybrid, an ion-kinetic electron-fluid code to simulate the global plasma interaction of unmagnetized Earth with the solar wind. We vary the global ionospheric emission rate, and …

Magnetosphere and Plasma Science with the Jupiter Icy Moons Explorer

Adam Masters, R. Modolo, E. Roussos, N. Krupp et autres

Abstract The Jupiter Icy Moons Explorer (JUICE) is a European Space Agency mission to explore Jupiter and its three icy Galilean moons: Europa, Ganymede, and Callisto. Numerous JUICE investigations concern the magnetised space environments containing low-density populations of charged particles that surround …

New Models of Jupiter's Magnetopause and Bow Shock through the Juno Prime Mission: Probabilistic Location, Shape, and Internally-driven Variation

Matthew Rutala, Caitriona M. Jackman, Corentin Kenelm Louis, Abigail Azari et autres

The interaction between Jupiter's magnetosphere and the solar wind is not well-constrained: while internal energetic plasma processes are thought to dominate plasma circulation, the solar wind nonetheless exerts significant control over the shape and scale of the whole structure. To better constrain …

Europa Modifies Jupiter's Plasma Sheet

J. Szalary, National Aeronautics and Space Administration (NASA), USDOE National Nuclear Security Administration (NNSA), J. Saur et autres

Jupiter's plasma sheet has been understood to be primarily composed of Io-genic sulfur and oxygen, along with protons at lower mass density. These ions move radially away from Jupiter, filling its magnetosphere. The material in the plasma sheet interacts with Europa, which …

Electron partial density and temperature over Jupiter's main auroral emission using Juno observations

F. Allegrini, W. S. Kurth, S. S. Elliott, J. Saur et autres

We present a survey of electron partial densities (i.e., the portion of the total density measured between ~0.05 and 100 keV) and temperatures in Jupiter’s main auroral emission region using plasma measurements from the Jovian Auroral Distributions Experiment (JADE) on Juno. The …
