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]
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

Petrographic survey of lunar regolith breccias [PDF]
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 ...

Lunar Rover with Multiple Science Handling Capability [PDF]
A rover design study was undertaken for exploration of the Moon. Rovers that have been launched in the past carried a suite of science payload either onboard its body or on the robotic arm’s end.

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
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 ...
