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…
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…
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…
Mass supply from Io to Jupiter's magnetosphere
L. Roth, A. Blöcker, K. de Kleer +24
Since the Voyager mission flybys in 1979, we have known the moon Io to be both volcanically active and the main source of plasma in the vast magnetosphere of Jupiter. Material lost…
