Observations of Saturn's satellite Enceladus using Cassini's Visual and Infrared Mapping Spectrometer instrument were obtained during three flybys of Enceladus in 2005. Enceladus' surface is composed mostly of nearly pure water ice except near its south pole, where there are light organics, CO2, and amorphous and crystalline water ice, particularly in the region dubbed the “tiger stripes.” An upper limit of 5 precipitable nanometers is derived for CO in the atmospheric column above Enceladus… 
The surface composition of Enceladus: clues from the Ultraviolet
Abstract The reflectance of Saturn's moon Enceladus has been measured at far ultraviolet (FUV) wavelengths (115–190 nm) by Cassini's UltraViolet Imaging Spectrograph (UVIS). At visible and near
Surface composition of Hyperion
Observations of Hyperion’s surface in the ultraviolet and near-infrared spectral regions with two optical remote sensing instruments on the Cassini spacecraft at closest approach during a fly-by on 25–26 September 2005 are reported.
Cassini Observes the Active South Pole of Enceladus
The shape of Enceladus suggests a possible intense heating epoch in the past by capture into a 1:4 secondary spin/orbit resonance.
Chemical and phase composition of Enceladus: Insights from Cassini data
Compositional information obtained with Cassini instruments during Enceladus and Saturn’s E ring flybys is used to constrain chemical and phase (minerals, ices, clathrates, organics, liquids)
Methanol on Enceladus
Near infrared spectra of the surface of Enceladus returned by Cassini show the presence of an absorption feature at 3.53 μm, ascribed by Brown et al. (2006) to “short chain organics,” and by Newman
A Clathrate Reservoir Hypothesis for Enceladus' South Polar Plume
We hypothesize that active tectonic processes in the south polar terrain of Enceladus, the 500-kilometer-diameter moon of Saturn, are creating fractures that cause degassing of a clathrate reservoir
Enceladus' Varying Imprint on the Magnetosphere of Saturn
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.
Composition of Titan's Surface
The Huygens Probe returned the first in situ data on Titan's surface composition in January 2005. Although Huygens landed on a dry plain, the Gas Chromatograph Mass Spectrometer (GCMS) showed


Cassini Observes the Active South Pole of Enceladus
The shape of Enceladus suggests a possible intense heating epoch in the past by capture into a 1:4 secondary spin/orbit resonance.
Enceladus' Water Vapor Plume
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.
Cassini Encounters Enceladus: Background and the Discovery of a South Polar Hot Spot
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.
Near-Infrared Spectra of Icy Outer Solar System Surfaces: Remote Determination of H2O Ice Temperatures
We present new 1.20 to 2.35 μm spectra of satellites of Jupiter, Saturn, and Uranus, and the rings of Saturn, obtained in 1995 and 1998 at Lowell Observatory. For most of the target objects, our data
Identification of a Dynamic Atmosphere at Enceladus with the Cassini Magnetometer
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.
The Volcanic and Tectonic History of Enceladus
Abstract Enceladus has a protracted history of impact cratering, cryovolcanism, and extensional, compressional, and probable strike–slip faulting. It is unique in having some of the outer Solar
Cryovolcanism on the icy satellites
Evidence of past cryovolcanism is widespread and extremely varied on the icy satellites. Some cryovolcanic landscapes, notably on Triton, are similar to many silicate volcanic terrains, including
