Surface Features of Ganymede Revealed in Jupiter‐Shine by Juno’s Stellar Reference Unit

Geophysical Research Letters, 2022
On 7 June 2021, Juno crossed the orbital path of Jupiter’s moon Ganymede, flying within 1,046 km of the surface. Juno’s low‐light‐sensitive Stellar Reference Unit (SRU) navigation camera captured an image of the satellite’s dark side in a region of ...

The Lense-Thirring effect in the Jovian system of the Galilean satellites and its measurability [PDF]

, 2005
In this paper we investigate the possibility of measuring the post-Newtonian general relativistic gravitomagnetic Lense-Thirring effect in the Jovian system of its Galilean satellites Io, Europa, Ganymede and Callisto in view of recent developments in ...

Inter‐Orbit Variability of Jupiter's Current Sheet Morphology

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The structure of Jupiter's magnetosphere reflects the combined effects of a strong intrinsic field and an extended hinged current sheet whose morphology varies with solar wind forcing. We present a study of Jupiter's magnetodisc that combines the UCL‐AGA magnetodisc code with Khurana's generalized, hinged current sheet models (1992/2022) to ...

Three-dimensional Magnetohydrodynamic Simulations of Periodic Variations of Ganymede’s Footprint

The Astrophysical Journal
Alfvénic power is generated through the interaction between the mini-magnetosphere of Ganymede and the corotating flow of the Jovian plasma, contributing to the formation of the Ganymede auroral footprint at Jupiter’s ionosphere.

Energetic Charged Particle Fluxes Relevant to Ganymede's Polar Region

Geophysical Research Letters, 2022
The JEDI instrument made measurements of energetic charged particles near Ganymede during a close encounter with that moon. Here we find ion flux levels are similar close to Ganymede itself but outside its magnetosphere and on near wake and open field ...

Invariant Manifolds, the Spatial Three-Body Problem and Space Mission Design [PDF]

, 2001
The invariant manifold structures of the collinear libration points for the spatial restricted three-body problem provide the framework for understanding complex dynamical phenomena from a geometric point of view.

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Driver of Energetic Electron Precipitation in the Vicinity of Ganymede

Geophysical Research Letters, 2023
The driver of energetic electron precipitation into Ganymede's atmosphere has been an outstanding open problem. During the Juno flyby of Ganymede on 7 June 2021, Juno observed significant downward‐going electron fluxes inside the bounce loss cone of ...

Design of a Multi-Moon Orbiter [PDF]

, 2003
The Multi-Moon Orbiter concept is introduced, wherein a single spacecraft orbits several moons of Jupiter, allowing long duration observations. The ΔV requirements for this mission can be low if ballistic captures and resonant gravity assists by ...

Impact-Generated Dust Clouds Surrounding the Galilean Moons

, 2003
Tenuous dust clouds of Jupiter's Galilean moons Io, Europa, Ganymede and Callisto have been detected with the in-situ dust detector on board the Galileo spacecraft.
