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

[1] We analyze Cassini magnetic field observations from the only two polar flybys of Saturn's largest icy satellite Rhea (R2 on 02 March 2010 and R3 on 11 January 2011) which are scheduled between

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.
