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…
The ocean worlds science case for the Pollux spectropolarimeter
Vincent Hue, Bilal Benmahi, Mathieu Barthelemy +9
Pollux is a candidate European instrument contribution to the Habitable Worlds Observatory (HWO), designed to advance our understanding of the formation and evolution of cosmic str…
Assessing Ocean World Habitability with HWO
Richard J. Cartwright, Lynnae Quick, Marc Neveu +5
The instrument payload of the future Habitable Worlds Observatory (HWO) will span a wide range of wavelengths, including the ultraviolet (UV) region that cannot be easily accessed…
Laboratory Investigation of CO2-Driven Enhancement of Radiolytic H2O2 on Europa and Other Icy Moons
Bereket D. Mamo, Ujjwal Raut, Ben D. Teolis +5
Observations of Europa's leading hemisphere reveal elevated H2O2 in the warmer, low latitude chaos terrains compared to the colder, polar regions. This distribution disagrees with…
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…
