The stratification of regolith on celestial objects [PDF]
Icarus, 2015 All atmosphere-less planetary bodies are covered with a dust layer, the so-called regolith, which determines the optical, mechanical and thermal properties of their surface. These properties depend on the regolith material, the size distribution of the particles it consists of, and the porosity to which these particles are packed.

A new method to determine the grain size of planetary regolith [PDF]
, 2012 Airless planetary bodies are covered by a dusty layer called regolith. The grain size of the regolith determines the temperature and the mechanical strength of the surface layers. Thus, knowledge of the grain size of planetary regolith helps to prepare future landing and/or sample-return missions.

Micro-meteoroid seismic uplift and regolith concentration on kilometric scale asteroids [PDF]
, 2015 Seismic shaking is an attractive mechanism to explain the destabilisation of regolith slopes and the regolith migration found on the surfaces of asteroids (Richardson et al. 2004; Miyamoto et al. 2007). Here, we use a continuum mechanics method to simulate the seismic wave propagation in an asteroid.

Objective Regolith-Landform Mapping in a Regolith Dominated Terrain to Inform Mineral Exploration [PDF]
Geosciences, 2018 An objective method for generating statistically sound objective regolith-landform maps using widely accessible digital topographic and geophysical data without requiring specific regional knowledge is demonstrated and has application as a first pass ...

Regolith behavior under asteroid-level gravity conditions: low-velocity impact experiments [PDF]
arXiv, 2018 The dusty regolith covering the surfaces of asteroids and planetary satellites differs in size, shape, and composition from terrestrial soil particles and is subject to very different environmental conditions. Experimental studies of the response of planetary regolith in the relevant environmental conditions are thus necessary to facilitate future ...

Telomere dynamics and oxidative stress in Arabidopsis grown in lunar regolith simulant [PDF]
Frontiers in Plant ScienceNASA envisions a future where humans establish a thriving colony on the Moon by 2050. Plants will be essential for this endeavor, but little is known about their adaptation to extraterrestrial bodies.

Cosmogenic nuclide weathering biases: corrections and potential for denudation and weathering rate measurements [PDF]
Geochronology, 2022 Cosmogenic radionuclides (CRNs) are the standard tool to derive centennial-to-millennial timescale denudation rates; however, it has been demonstrated that chemical weathering in some settings can bias CRNs as a proxy for landscape denudation. Currently,

Self-Organization Characteristics of Lunar Regolith Inferred by Yutu-2 Lunar Penetrating Radar
Remote Sensing, 2021 Most previous studies tend to simplify the lunar regolith as a homogeneous medium. However, the lunar regolith is not completely homogeneous, because there are weak reflections from the lunar regolith layer.
