Abstract Grain morphology is a fundamental characteristic of lunar soil that influences its mechanical properties, sintering behavior, and in situ resource utilization. However, traditional two‐dimensional imaging methods are time‐consuming and lack full three‐dimensional (3D) structural information. This study presents an automated deep learning‐based

Hydrous Components of Dusty Surfaces Inferred From Zhurong In Situ Observations
Abstract The ubiquitous hydration features observed by Zhurong rover provided new insights into Mars aqueous paleoenvironments. However, the impact of the Martian dust was not previously discussed. Here, we conduct a joint analysis of the Multispectral Camera and Short‐Wave Infrared data to constrain the surface composition. The results show that these

Discovery of a Lunar Cold Spot at Apollo 16's South Ray Crater
Abstract Lunar cold spots are extensive, ray‐like regions of reduced nighttime temperature surrounding young impact craters. Using improved Diviner temperature maps, we identify a faint cold spot surrounding South Ray crater at the Apollo 16 landing site.

Effect of Soil Type on Running Performance of Small Lunar Rover
It is very easy for a small lunar rover to slip on the regolith of the lunar surface and become stuck. Previous studies have quantitatively evaluated the effects of wheel geometry, such as elliptical or eccentric wheels, on the performance of a rover ...

Characterisation of Groundwater Flow in the Deltaic Aquifer‐Aquitard System
This study employs a permanent multilevel groundwater monitoring system to capture high‐resolution, hourly groundwater level fluctuations in a deltaic basin, providing an unprecedented dataset for evaluating groundwater flow dynamics. Fractal behaviours are used to explore the deltaic groundwater flow system.

Interactions of rare earth elements with living organisms and emerging biotechnical applications
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

A Goniometric System for Photometric and Polarization Measurements of Planetary Regolith Analogs
Abstract The Planetary Surface Texture Laboratory at the Johns Hopkins University Applied Physics Laboratory is a facility for the study of the photometric and polarization behavior of regolith analogs using an ∼1.5‐m‐radius arc goniometer system. This system characterizes the photometric and polarization response of granular materials (planetary ...
