Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

Integrating Grain to Ground Motion Data for Critical Rock Bridge and Slope Failure Analysis
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Rock masses can fail catastrophically with little warning, yet their stability depends on hidden internal connections that channel forces and localise damage. Among these, rock bridges–a “known unknown” in slope mechanics–lock fractured rock and control how failure unfolds, but their concealed geometry and uncertain strength obscure where and ...

An Open Database of Lunar Regolith and Simulants Properties
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Lunar regolith, the layer of unconsolidated material covering the Moon's surface, is central to the science and technology developed for the Moon, notably related to in‐situ science investigations, resource utilization, surface infrastructure, and mobility systems.

Particle‐Scale Mechanics of a Regolith‐Type Soil
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT The existing studies have reported that the surface of Mars shows the presence of materials having igneous origin, including basalt and regolith‐type coarse soils. These findings are affected by significant uncertainties and, therefore, the selection of simulants for various exploration applications, including surface mobility of rovers ...

Feature Databases in Planetary Geology
Lecture Notes in Geoinformation and Cartography, 2019The study of planetary surfaces is as diverse as the surfaces themselves, yet almost all can be assisted by the existence of feature databases. Databases provide a single, standardized source that can serve as an important reference for different studies that involve the same kinds of landforms.

Planetary and Space Science, 2021
Abstract I engage the philosophy of geology, and the philosophy of planetary geomorphology in particular, offering a perspective from the standpoint of a Mars geographer who is acquainted with both experimental and social research. I discuss the nature of geological reasoning and probe its somewhat paradoxical commitment to both a physical realism ...

Experimentation in planetary geology
Reviews of Geophysics, 1987The reasons for conducting experimentation are as varied as the topics that are studied. Whether a specific parameter must be quantified or an attempt is being made to duplicate a peculiar process, all experiments are unified by a common, ultimate objective: to provide a tangible link between theory and observation, although a suitable theory is often ...
