Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
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…
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…
Long-Term Evolution of the Saturnian System
Matija Ćuk, Maryame El Moutamid, Giacomo Lari +5
Here we present the current state of knowledge on the long-term evolution of Saturn's moon system due to tides within Saturn. First we provide some background on tidal evolution, o…
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 '…
The Science Case for Spacecraft Exploration of the Uranian Satellites
Richard J. Cartwright, Chloe B. Beddingfield, Tom Nordheim +14
The five classical Uranian moons are possible ocean worlds that exhibit bizarre geologic landforms, hinting at recent surface-interior communication. However, Uranus' classical moo…
