Saturn's moon Rhea had been considered massive enough to retain a thin, externally generated atmosphere capable of locally affecting Saturn's magnetosphere. The Cassini spacecraft's in situ observations reveal that energetic electrons are depleted in the moon's vicinity. The absence of a substantial exosphere implies that Rhea's magnetospheric interaction region, rather than being exclusively induced by sputtered gas and its products, likely contains solid material that can absorb…

Mapping Magnetospheric Equatorial Regions at Saturn from Cassini Prime Mission Observations
Saturn’s rich magnetospheric environment is unique in the solar system, with a large number of active magnetospheric processes and phenomena. Observations of this environment from the Cassini…

Fundamental Plasma Processes in Saturn's Magnetosphere
In this chapter, we review selected fundamental plasma processes that control the extensive space environment, or magnetosphere, of Saturn (see Chapter 9, for the global context). This writing occurs…
Cassini Finds an Oxygen–Carbon Dioxide Atmosphere at Saturn’s Icy Moon Rhea
TLDR
The flyby measurements of the Cassini spacecraft at Saturn’s moon Rhea reveal a tenuous oxygen (O2)–carbon dioxide (CO2) atmosphere that appears to be sustained by chemical decomposition of the surface water ice under irradiation from Saturn's magnetospheric plasma.
Composition, Structure, Dynamics, and Evolution of Saturn's Rings
Cassini observations confirm that Saturn’s rings are predominantly water ice. The particles in Saturn’s rings cover a range of sizes, from dust to small moons. Occultation results show the particles…
Analysis of Cassini magnetic field observations over the poles of Rhea

Atmospheres and Plasma Interactions at Saturn’s Largest Inner Icy Satellites
We explore the possible existence of atmospheres on Saturn's icy satellites, Mimas, Enceladus, Tethys, Dione, and Rhea. Only the most massive satellite, Rhea, has the potential to hold a thin oxygen…
Enceladus' Varying Imprint on the Magnetosphere of Saturn
TLDR
The bombardment of Saturn's moon Enceladus by >20–kiloelectron volt magnetospheric particles causes particle flux depletions in regions magnetically connected to its orbit, which provide key radial diffusion coefficients for energetic electrons and an independent measure of the inner magnetosphere's rotation velocity.
