Tracing the source of carbon oxides on the large moons of Uranus

Richard J. Cartwright, Sasha Cryan, Rosario Brunetto +15

The Uranian moons Ariel, Umbriel, Titania, and Oberon are enriched in CO2 mixed with CO, but the origin(s) of these carbon oxides, be they primarily native or radiolytic, remains u…

JWST Reveals Spectral Tracers of Recent Surface Modification on Europa

Richard J. Cartwright, Charles A. Hibbits, Bryan J. Holler +9

Europa has been modified by a variety of geologic processes, exposing internally-derived materials that are heavily irradiated by charged particles trapped in Jupiter's magnetosphe…

Revealing Callisto's carbon-rich surface and CO2 atmosphere with JWST

Richard J. Cartwright, Geronimo L. Villanueva, Bryan J. Holler +18

We analyzed spectral cubes of Callisto's leading and trailing hemispheres, collected with the NIRSpec Integrated Field Unit (G395H) on the James Webb Space Telescope. These spatial…

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…
