Endogenic and Exogenic Contributions to Visible-wavelength Spectra of Europa's Trailing Hemisphere
Samantha K. Trumbo, Michael E. Brown, Kevin P. Hand
The composition of Europa's trailing hemisphere reflects the combined influences of endogenous geologic resurfacing and exogenous sulfur radiolysis. Using spatially resolved visibl…
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…
Evidence for ammonia-bearing species on the Uranian satellite Ariel supports recent geologic activity
Richard J. Cartwright, Chloe B. Beddingfield, Tom A. Nordheim +6
We investigated whether ammonia-rich constituents are present on the surface of the Uranian moon Ariel by analyzing 32 near-infrared reflectance spectra collected over a wide range…
HO within chaos terrain on Europa's leading hemisphere
Samantha K. Trumbo, Michael E. Brown, Kevin P. Hand
Hydrogen peroxide is part of an important radiolytic cycle on Europa and may be a critical source of oxidants to the putative subsurface ocean. The surface geographic distribution…
A Search for Water Vapor Plumes on Europa using SOFIA
William Sparks, M. Richter, C. deWitt +8
We present mid-infrared SOFIA/EXES spectroscopy of Europa, seeking direct evidence of the presence of water vapor arising from plumes venting from the surface of Europa. We place q…
A New Spectral Feature on the Trailing Hemisphere of Europa at 3.78 microns
Samantha K. Trumbo, Michael E. Brown, Patrick D. Fischer +1
We present hemispherically resolved spectra of the surface of Europa from ~3.1--4.13 microns, which we obtained using the near infrared spectrometer NIRSPEC on the Keck II telescop…
