Abstract The surfaces of the large uranian satellites are characterized by a mixture of H2O ice and a dark, potentially carbon-rich, constituent, along with CO2 ice. At the mean heliocentric distance of the uranian system, native CO2 ice should be removed on timescales shorter than the age of the Solar System. Consequently, the detected CO2 ice might be actively produced. Analogous to irradiation of icy moons in the Jupiter and Saturn systems, we hypothesize that charged particles caught in… Expand
Surface modification of icy satellites: Space weathering of the large moons of Uranus and alluvial fan formation on Saturn’s moon Titan
The surfaces of the large Uranian satellites are characterized by a mixture of H2O ice and a dark, potentially carbon-rich, constituent, along with CO2 ice. At the mean heliocentric distance of theExpand
Probing the regoliths of the classical Uranian satellites: Are their surfaces mantled by a layer of tiny H2O ice grains?
Abstract We investigate whether the surfaces of the classical moons of Uranus are compositionally stratified, with a thin veneer of mostly tiny H2O ice grains (≤2 μm diameters) mantling a lower layerExpand
Red material on the large moons of Uranus: Dust from the irregular satellites?
Abstract The large and tidally-locked “classical” moons of Uranus display longitudinal and planetocentric trends in their surface compositions. Spectrally red material has been detected primarily onExpand
The Science Case for Spacecraft Exploration of the Uranian Satellites: Candidate Ocean Worlds in an Ice Giant System
The 27 satellites of Uranus are enigmatic, with dark surfaces coated by material that could be rich in organics. Voyager 2 imaged the southern hemispheres of Uranus’s five largest “classical”Expand
A Wunda-full world? Carbon dioxide ice deposits on Umbriel and other Uranian moons
Abstract Carbon dioxide has been detected on the trailing hemispheres of several Uranian satellites, but the exact nature and distribution of the molecules remain unknown. One such satellite,Expand
Composition of Pluto’s small satellites: Analysis of New Horizons spectral images
Abstract On July 14, 2015, NASA’s New Horizons spacecraft encountered the Pluto-system. Using the near-infrared spectral imager, New Horizons obtained the first spectra of Nix, Hydra, and KerberosExpand
Comparative Kbology: Using Surface Spectra of Triton, Pluto, and Charon to Investigate Atmospheric, Surface, and Interior Processes on Kuiper Belt Objects
We present the results of an investigation to determine the longitudinal (zonal) distributions and temporal evolution of ices on the surface of Triton. Between 2002 and 2014, we obtained 63 nights ofExpand
Nature, distribution and origin of CO2 on Enceladus
Abstract We present the first map of CO2 at the surface of Enceladus using data obtained by the Cassini Visible-Infrared Mapping Spectrometer (VIMS). In order to measure the weak and narrow CO2Expand
Evidence for Ammonia-bearing Species on the Uranian Satellite Ariel Supports Recent Geologic Activity
We investigated whether ammonia-rich constituents are present on the surface of the Uranian moon Ariel by analyzing 32 near-infrared reflectance spectra collected over a wide range of sub-observerExpand
Modern Mars' geomorphological activity, driven by wind, frost, and gravity
Abstract Extensive evidence of landform-scale martian geomorphic changes has been acquired in the last decade, and the number and range of examples of surface activity have increased as moreExpand


Carbon dioxide on the satellites of Saturn: Results from the Cassini VIMS investigation and revisions to the VIMS wavelength scale
Abstract Several of the icy satellites of Saturn show the spectroscopic signature of the asymmetric stretching mode of C–O in carbon dioxide (CO2) at or near the nominal solid-phase laboratoryExpand
Detection of ozone on Saturn's satellites Rhea and Dione
The identification of O3 in spectra of the saturnian satellites Rhea and Dione indicates the presence of trapped O3 is thus no longer unique to Ganymede, suggesting that special circumstances may not be required for its production. Expand
Effects of charged particles on the surfaces of the satellites of Uranus
Measurements of the ion and electron fluxes in the Uranian magnetosphere made by the low-energy charged particle (LECP) instrument on the Voyager 2 spacecraft are used to discuss possibleExpand
Distributions of H2O and CO2 ices on Ariel, Umbriel, Titania, and Oberon from IRTF/SpeX observations
We present 0.8–2.4 μm spectral observations of uranian satellites, obtained at IRTF/SpeX on 17 nights during 2001–2005. The spectra reveal for the first time the presence of CO2 ice on the surfacesExpand
Geology of the Uranian satellites

Observed Ices in the Solar System
Ices have been detected and mapped on the Earth and all planets and/or their satellites further from the sun. Water ice is the most common frozen volatile observed and is also unambiguously detectedExpand
Compositional maps of Saturn's moon Phoebe from imaging spectroscopy
Imaging spectroscopy of Phoebe resulting from the Cassini–Huygens spacecraft encounter on 11 June 2004 mapped ferrous-iron-bearing minerals, bound water, trapped CO2, probable phyllosilicates, organics, nitriles and cyanide compounds, indicating a surface of cometary origin. Expand
Voyager 2 in the Uranian System: Imaging Science Results
Voyager 2 images of the southern hemisphere of Uranus indicate that submicrometersize haze particles and particles of a methane condensation cloud produce faint patterns in the atmosphere, and Voyager images confirm the extremely low albedo of the ring particles. Expand
