A Novel Soil Chronometer: Uranium Comminution Ages Measure Soil Production Rates in a Deep Granitic Weathering Profile

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Soil production, through bedrock weathering, regulates landscape evolution, biogeochemical cycles, and societal sustainability, yet quantifying soil production rates (SPRs) remains difficult due to limited tools. Here, we present a new framework for measuring SPRs based on uranium comminution ages and validate this approach at a deep granitic ...

Performance of hydrogen-rich materials in combination with lunar regolith for shielding against GCR, albedo, and SPEs on the surface of the moon studied using MULASSIS [PDF]

open access: yesAIP Advances
The moon is the most likely location for future human habitation. The radiation exposure from the combination of galactic cosmic rays, solar particle events, and albedo radiation on the Moon’s surface is one of the major obstacles to permanent settlement

A Miniaturized 3D Heat Flux Sensor to Characterize Heat Transfer in Regolith of Planets and Small Bodies

open access: yesSensors, 2020
The objective of this work is to present the first analytical and experimental results obtained with a 3D heat flux sensor for planetary regolith. The proposed structure, a sphere divided in four sectors, is sensible to heat flow magnitude and angle ...

Petrographic survey of lunar regolith breccias [PDF]

open access: yes
Regolith breccias from the Moon and from parent bodies of some meteorites may provide samples of ancient regoliths which have been frozen in time. If these rocks were essentially closed at some earlier time and that time can be determined, then these ...

Investigation on the Coherent Component of SHARAD Surface Echo and Surface Roughness: Scaling Behavior and Influence of Hurst Exponent

open access: yesEarth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The radar surface echo can be separated into coherent and incoherent components by statistical approaches, and the coherent component can be described by a backscattering model related to the RMS height. According to backscattering models for fractal surfaces, the coherent power in decibels decreases with RMS height on a scale independent of ...

Photometry of Lunar Swirls in Comparison to Fresh Crater Ejecta

open access: yesThe Planetary Science Journal
Swirls are sinuous high-reflectance lunar surface features collocated with crustal magnetic anomalies. These bright features and their geographical relationship to magnetic anomalies have been studied for decades, although their cause remains unclear ...
