Diurnal and Seasonal Mapping of Martian Ices With EMIRS
Geophysical Research Letters, 2023 Condensation and sublimation of ices at the surface of the planet is a key part of both the Martian H2O and CO2 cycles, either from a seasonal or diurnal aspect.

Predicting the Effect of Surface Properties on Enceladus for Landing
The Planetary Science Journal, 2023 The prospect of landing on the surface of Enceladus comes with the question of whether the surface conditions permit selection and certification of one or more safe landing sites in an area of high science value.

Longitudinal Variation of H2O Ice Absorption on Miranda
The Planetary Science Journal, 2022 Many tidally locked icy satellites in the outer solar system show leading/trailing hemispherical asymmetries in the strength of near-infrared (NIR) H _2 O ice absorption bands, in which the absorption bands are stronger on the leading hemisphere. This is

Are NH3 and CO2 Ice Present on Miranda?
The Planetary Science Journal, 2023 Published near-IR spectra of the four largest classical Uranian satellites display the presence of discrete deposits of CO _2 ice, along with subtle absorption features around 2.2 μ m.

A CO2 Cycle on Ariel? Radiolytic Production and Migration to Low-latitude Cold Traps
The Planetary Science Journal, 2022 CO _2 ice is present on the trailing hemisphere of Ariel but is mostly absent from its leading hemisphere. The leading/trailing hemispherical asymmetry in the distribution of CO _2 ice is consistent with radiolytic production of CO _2 , formed by charged

GEOLOGICAL MAPPING OF PLUTO AND CHARON USING NEW HORIZONS DATA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 Pluto and Charon exhibit strikingly different surface appearances, despite their similar densities and presumed bulk compositions. Systematic mapping has revealed that much of Pluto’s surface can be attributed to surface-atmosphere interactions and the ...

Crystallization Kinetics of Vitreous Magnesium Sulfate Hydrate and Implications for Europa’s Surface
The Planetary Science Journal, 2023 Brines consistent with that expected for Europa’s global subsurface ocean have been shown to form vitreous salt hydrates when frozen. We report experiments examining the crystallization kinetics of vitreous MgSO _4 hydrate in order to better understand ...
