Thermal Escape of Atomic Hydrogen on Mars: A Comprehensive View With a General Circulation Model

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Mars loses water mainly through the photodissociation of water vapor, followed by the thermal escape of light hydrogen atoms. Observations have revealed large seasonal variations in hydrogen concentration in the upper thermosphere, peaking during southern summers and intensifying during dust storms.

Spectral Characterization of CO2‐H2O Ice Layering Under Controlled Mars Polar Conditions as Laboratory Analogs for Seasonal Cap Activity

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Seasonal CO2 and H2O ice blanket the Martian polar caps, and their spectral contributions mix during seasonal evolution. Particularly in late northern winter, the spectral signature of H2O ice obscures that of CO2 ice. Using the MARVIN chamber at York University, we produced controlled analogs of layered polar ice under Mars‐like pressure (∼6 ...
