Solar wind erosion of lunar regolith is suppressed by surface morphology and regolith properties

Communications Earth & Environment
Abstract Important aspects concerning the origin and formation of the Moon’s exosphere, its tenuous gas envelope, remain puzzling with uncertainties regarding the importance of different effects. Two competing processes — micrometeoroid impact vaporization and solar wind ion sputtering — are considered key contributors to the ejection of ...

Impact Craters Reveal a Deeper Rock‐Poor Regolith in the Lunar Highlands

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The only measurements of the highlands regolith occurred at the Apollo 14 and 16 landing sites, finding 10–15 m thick regolith; however, we show that the Apollo landing sites are anomalous due to their proximity to rare, highlands rocky craters and because they landed atop basin ejecta. Through observations of rocky crater populations, we show

Underestimation of Planetary Contraction Due To Obscuration by Surface Roughness: The Case of Mercury

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Estimating Mercury's radial contraction is key to understanding the planet's geodynamic evolution. Contraction has been inferred from mapped shortening structures, whose heterogeneous distribution contradicts the isotropic contraction expected from global cooling.

New Constraints on the Spatial and Temporal Evolution of the Lunar Surface Regolith

The Planetary Science Journal
The thickness of the lunar regolith is fundamental for interpreting surface processes, impact chronology, and the thermal and volatile evolution of the Moon, yet its global distribution and long-term history remain debated.
