Mastcam‐Z Spectrophotometric Properties of Materials at the Van Zyl Overlook, Jezero Crater
Abstract During Sols 63–65 of Mars 2020, Mastcam‐Z multispectral (442–1022 nm) images were acquired at Van Zyl Overlook (VZO), spanning phase angles from ∼0° to 150°, to model photometric parameters for seven surface units. These units included rocks, soils, regolith, and rover tracks near the Jezero landing site.

Geologically Recent Formation of Some Tesserae on Venus by Plains Deformation
Abstract Tessera is a pervasively deformed terrain type on Venus generally interpreted as the oldest preserved material on the surface. Large expanses of this terrain type are typically elevated and have been hypothesized to be felsic, perhaps analogous to Earth's continents and even to date from an era with a more Earth‐like climate earlier in Venus ...

Martian Proton Albedo as Signature of Near‐Surface Water
Abstract Understanding the Martian soil water budget is crucial not only for in situ resource utilization in future human missions to Mars, but also for reconstructing the geological and climatic history of the planet, as well as to assess the potential of ancient or even present microbial life.

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

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 ...
