During Cassini's close flyby of Enceladus on 14 July 2005, the High Rate Detector of the Cosmic Dust Analyzer registered micron-sized dust particles enveloping this satellite. The dust impact rate peaked about 1 minute before the closest approach of the spacecraft to the moon. This asymmetric signature is consistent with a locally enhanced dust production in the south polar region of Enceladus. Other Cassini experiments revealed evidence for geophysical activities near Enceladus' south pole: a… 
Cassini RPWS Dust Observation Near the Janus/Epimetheus Orbit
During the Ring Grazing orbits near the end of Cassini mission, the spacecraft crossed the equatorial plane near the orbit of Janus/Epimetheus (~2.5 Rs). This region is populated with dust particles
Cassini Encounters Enceladus: Background and the Discovery of a South Polar Hot Spot
TLDR
Cassini's Composite Infrared Spectrometer (CIRS) detected 3 to 7 gigawatts of thermal emission from the south polar troughs at temperatures up to 145 kelvin or higher, making Enceladus only the third known solid planetary body—after Earth and Io—that is sufficiently geologically active for its internal heat to be detected by remote sensing.
Does Enceladus Govern Magnetospheric Dynamics at Saturn?
Instruments on the Cassini spacecraft reveal that a heat source within Saturn's moon Enceladus powers a great plume of water ice particles and dust grains, a geyser that jets outward from the south
Signatures of Enceladus in Saturn's E ring
Dust production from Enceladus has long been suggested as the main source of dust in Saturn's E ring. This was supported by the observation that the ring's optical depth peaks close to the orbit of
Electron density inside Enceladus plume inferred from plasma oscillations excited by dust impacts
Enceladus' southern plume is one of the major discoveries of the Cassini mission. The water neutrals and water ice particles (dust) ejected by the cryovolcanic activity populate Saturn's E ring and
Dusty plasma of the Enceladus plume
Geological active south-pole fractures of the icy moon Enceladus produce a specific region, a so-called plume that extends up to 1000 km into space. The main constituents of the plume are electrons,
Large‐scale structure of Saturn's E‐ring
Geysers on the recently discovered, geologically active south‐polar region of the moon Enceladus are now recognized as the dominant source of material in Saturn's E ring. The ring was traditionally
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.

Enceladus' Water Vapor Plume
TLDR
The Cassini spacecraft flew close to Saturn's small moon Enceladus three times in 2005 and observed stellar occultations on two flybys and confirmed the existence, composition, and regionally confined nature of a water vapor plume in the south polar region of Ence Gladus.
Identification of a Dynamic Atmosphere at Enceladus with the Cassini Magnetometer
TLDR
The Cassini magnetometer has detected the interaction of the magnetospheric plasma of Saturn with an atmospheric plume at the icy moon Enceladus, consistent with local outgassing activity via a plume from the surface of the moon near its south pole.
Detection of an impact-generated dust cloud around Ganymede
Dust pervades the Solar System, and is concentrated in the ring systems surrounding the giant planets and along the plane of the planetary orbits (the Zodiacal cloud). Individual dust grains are
Seasonal variations in Saturn's E‐ring
By following the trajectories of a large number of particles we capture the seasonal variations of the density and spatial distributions of dust in Saturn's E‐ring. We have used an optimized set of
Cassini Observes the Active South Pole of Enceladus
TLDR
The shape of Enceladus suggests a possible intense heating epoch in the past by capture into a 1:4 secondary spin/orbit resonance.

The Cassini-Huygens Cosmic Dust Analyzer (CDA) is intended to provide direct observations of dust grains with masses between 10−19 and 10−9 kg in interplanetary space and in the jovian and saturnian
Cassini Ion and Neutral Mass Spectrometer: Enceladus Plume Composition and Structure
TLDR
INMS data indicate that the atmospheric plume and coma are dominated by water, with significant amounts of carbon dioxide, an unidentified species with a mass-to-charge ratio of 28 daltons (either carbon monoxide or molecular nitrogen), and methane.
