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…

Callisto from JWST: CO2-rich terrain on the leading hemisphere and global patterns of H2O ice

Maria Camarca, Katherine de Kleer, Richard J. Cartwright +5

We present maps of H2O, CO2, and a 4.57 um spectral feature across Callisto's surface observed using the James Webb Space Telescope (JWST). H2O ice was mapped by measuring band par…

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…

Mars, a Post-Habitable Planet?

Matteo Crismani, Richard Cartwright, Michael Chaffin +3

Mars provides a critical analog to once habitable exoplanets that have since lost their surface liquid water. The current atmospheric state of Mars retains the chemical fingerprint…

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…

PyISH: Python Integral Field Spectroscopy Simulation for HWO

Grace Sweetak, Breann Sitarski, Kevin France +2

The Habitable Worlds Observatory (HWO) will be a large ultraviolet/optical/near-infrared space telescope operating at the Sun-Earth Lagrange point L2. HWO was highly recommended by…

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…

Spectral trends across the rings and inner moons of Uranus and Neptune from JWST NIRCam images

M. M. Hedman, I. de Pater, R. Cartwright +8

JWST NIRCam images provide low-resolution spectra of the rings and inner moons orbiting Uranus and Neptune. These data reveal systematic variations in spectral parameters like the…

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…

JWST Reveals Varied Origins Between Jupiter's Irregular Satellites

Benjamin N. L. Sharkey, Andrew S. Rivkin, Richard J. Cartwright +3

We report observations of eight Jovian irregular satellites with JWST's NIRSpec instrument: Himalia, Elara, Pasiphae, Sinope, Lysithea, Carme, Ananke, and Themisto. Irregular satel…

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…

Are NH and CO ice present on Miranda?

Riley A. DeColibus, Nancy J. Chanover, Richard J. Cartwright

Published near-infrared spectra of the four largest classical Uranian satellites display the presence of discrete deposits of CO ice, along with subtle absorption features arou…
