Water-Ice Dominated Spectra of Saturn's Rings and Small Moons from JWST
M. M. Hedman, M. S. Tiscareno, M. R. Showalter +11
JWST measured the infrared spectra of Saturn's rings and several of its small moons (Epimetheus, Pandora, Telesto and Pallene) as part of Guaranteed Time Observation program 1247.…
The Nature of Low-Albedo Small Bodies from 3-m Spectroscopy: One Group that Formed Within the Ammonia Snow Line and One that Formed Beyond It
Andrew S. Rivkin, Joshua P. Emery, Ellen S. Howell +9
We present evidence, via a large survey of 191 new spectra along with previously-published spectra, of a divide in the 3-m spectral properties of the low-albedo asteroid populat…
A CO2 cycle on Ariel? Radiolytic production and migration to low latitude cold traps
Richard J. Cartwright, Tom A. Nordheim, David DeColibus +11
CO2 ice is present on the trailing hemisphere of Ariel but is mostly absent from its leading hemisphere. The leading/trailing hemispherical asymmetry in the distribution of CO2 ice…
The science case for spacecraft exploration of the Uranian satellites: Candidate ocean worlds in an ice giant system
Richard J. Cartwright, Chloe B. Beddingfield, Tom A. Nordheim +15
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' five largest '…
Evidence for sulfur-bearing species on Callisto's leading hemisphere: Sourced from Jupiter's irregular satellites or Io?
Richard J. Cartwright, Tom A. Nordheim, Dale P. Cruikshank +5
We investigated whether sulfur-bearing species are present on the icy Galilean moon Callisto by analyzing eight near-infrared reflectance spectra collected over a wide range of sub…
Evidence for ammonia-bearing species on the Uranian satellite Ariel supports recent geologic activity
Richard J. Cartwright, Chloe B. Beddingfield, Tom A. Nordheim +6
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…
