A Miniaturized 3D Heat Flux Sensor to Characterize Heat Transfer in Regolith of Planets and Small Bodies

Sensors, 2020
The objective of this work is to present the first analytical and experimental results obtained with a 3D heat flux sensor for planetary regolith. The proposed structure, a sphere divided in four sectors, is sensible to heat flow magnitude and angle ...

The Moon's Crust and Upper Mantle Discontinuities Revealed by Seismic Interferometry Methods Applied to Apollo Seismic Data

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Seismic determination of the Moon's crustal thickness is crucial for understanding its formation, composition, and evolution. Additionally, crustal thicknesses below seismic stations serve as anchoring points for 3D crustal thickness maps derived from gravity and topography field variations.

Photometry of Lunar Swirls in Comparison to Fresh Crater Ejecta

The Planetary Science Journal
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 ...

The Influence of Space Weathering on the Far‐Ultraviolet Reflectance of Apollo‐Era Soils

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Building on our previous studies of the far‐ultraviolet (FUV) reflectance of Apollo soil 10084 and lunar soil simulants JSC‐1A and LMS‐1 (Gimar et al., 2022, https://doi.org/10.1029/2022je007508; Raut et al., 2018, https://doi.org/10.1029/2018je005567), we present new FUV results for Apollo soils 68501 and 71061. Heavily weathered soils (68501,

Evolution of Terrestrial Planetary Bodies and Implications for Habitability

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.

Ground-penetrating radar investigation of regolith thickness on a periglacial alpine summit flat, Uinta Mountains, Utah, USA

Arctic, Antarctic, and Alpine Research
Summit flats are low-relief, gently sloping landforms common in periglacial mountain environments. Apart from at their edges where summit flats are truncated by glacial headwalls and at their crests where isolated tors are occasionally present, bedrock ...

Structural Analysis of Lunar Regolith from LPR CH-2 Data Based on Adaptive f-x E MD: LPR Data Processed by Adaptive f-x EMD

Advances in Astronomy, 2019
The Lunar Penetrating Radar (LPR) is one of the important scientific payloads in China’s Chang’E-3 (CE-3) to image within 100 m below the lunar surface. The acquired LPR data is significant for the research of lunar geological structure.
