Revealing the Internal Structure of Mars‐Analog Glaciers From Drone‐Based Radar Sounding
Abstract Martian debris‐covered glaciers (DCGs) contain large quantities of water ice beneath a protective layer of rock and dust. Properties of the overlying regolith such as density and depth to ice are critical parameters for guiding in situ resource utilization (ISRU) of water and coring missions targeting potential habitats.

Influence of Mars Topography on Neutral Surface Radiation: Modeling and MSL/RAD Observations
Abstract Since landing in 2012, the Radiation Assessment Detector (RAD) onboard the Mars science laboratory (MSL) Curiosity rover has encountered different local landscapes, which have induced variations in the local surface environment. The aim of this study is to include realistic and site‐specific local topography for any position in a radiation ...

Asymmetric Crater Relaxation on an Ice‐Rich Ceres Driven by Insolation
Abstract Ceres has a high ice content within its crust and is the closest dwarf planet to the sun. The resultant high insolation levels at Ceres' surface (in comparison to the outer solar system) leads to high variations in surface temperature, which is dependent on both latitude and orientation of the slope (i.e., equatorward‐ or poleward‐facing).

Abstract The lunar south pole features permanently shadowed regions (PSRs) that never receive direct sunlight. These regions maintain cold temperatures that potentially trap and accumulate volatiles over geologic timescales. Within NASA's Artemis candidate landing regions, we identified 130 candidate landing sites (CLSs) that satisfy the Human Landing ...

Abstract The magnetic Prandtl number in the slow solar wind is estimated by using magnetic and velocity Reynolds numbers. The Prandtl number quantifies the ratio of kinetic to magnetic diffusion rates in a plasma, and indicates which process dominates the transport dynamics in a fluid.
