Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.Abstract We use Particle‐In‐Cell (PIC) simulations to investigate the charging characteristics inside deep cavities on the lunar surface under the solar wind plasma conditions. Specifically, we systematically study the dependence of the cavity bottom potential on plasma flow velocity and cavity aspect ratio.

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract Regolith samples from the lunar south pole are expected to contain material from the ancient lunar crust and potentially the uppermost mantle, excavated by the South Pole‐Aitken (SPA) impact. In this study, we aim to understand the impact resurfacing processes following the SPA impact and the subsequent redistribution of primordial crust and ...

Evaluating the Depth–Age Hypothesis for the Evolution of the Lunar Regolith
The Planetary Science JournalLunar regolith is the fractured rock layer covering most of the lunar surface. This rock is fractured into regolith primarily by repeated meteorite impacts over eons.

E3S Web of Conferences, 2018 This study was performed in order to verify viability of using finite difference method and proposed simple astrometrical model for modelling heat transfer in lunar regolith. The concept was examined by developing FD model of heat flow for upper 0,9 m of

Lunar Regolith Temperature Variation in the Rümker Region Based on the Real-Time Illumination
Remote Sensing, 2020 Chang’E-5 will be China’s first sample−return mission. The proposed landing site is at the late-Eratosthenian-aged Rümker region of the lunar nearside.

Accumulation of Dust on a Surface and the Subsequent Formation of Compact Aggregate Piles
Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract Dust aggregation is a prominent topic in space physics, yet the accumulation of dust on surfaces in airless environments remains poorly understood. It is commonly assumed that, during the initial stages of dust deposition, particles spread uniformly to form a monolayer.

Sintering lunar regolith pellets: a comparison of four samples from Apollo 11, 15, and 16
Materials Today AdvancesLunar regolith sintering is proposed as a technique to produce consolidated objects on the lunar surface from locally sourced materials. Understanding the sintering behaviour of real lunar regolith is necessary to optimise this process, however, due to ...

An investigation of the thermal shock resistance of lunar regolith and the recovery of hydrogen from lunar soil heated using microwave radiation [PDF]
The objective is to develop a better understanding of the thermal shock properties of lunar regolith sintered using 2.45 GHz electromagnetic radiation and to do a preliminary study into the recovery of bound hydrogen in lunar soil heated using 2.45 GHz ...

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract This study presents a 1:100,000 scale geologic map of the region encompassing Mons Mouton, Mons Malapert, and Cabeus crater, highlighting the region's geologic diversity. Based on location and topography, Mons Mouton and Mons Malapert are interpreted as remnant massifs of the South Pole‐Aitken (SPA) basin rim.
