Mid‐Infrared Reflectance and Emissivity Spectra of High Porosity Regoliths

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract Mid‐infrared (MIR; 5–35 μm) spectroscopy is often used for mineralogical identification on planetary surfaces. Laboratory spectra aiding remote sensing observations are typically performed in reflection geometries, while MIR spectra of planetary surfaces are typically obtained via emission.

Rock Location and Property Analysis of Lunar Regolith at Chang’E-4 Landing Site Based on Local Correlation and Semblance Analysis

Remote Sensing, 2020
The Lunar Penetrating Radar (LPR) onboard the Yutu-2 rover from China’s Chang’E-4 (CE-4) mission is used to probe the subsurface structure and the near-surface stratigraphic structure of the lunar regolith on the farside of the Moon.

Thermal Infrared Spectra of the Moon: Results From the Lucy Thermal Emission Spectrometer Observations

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract The Lucy Thermal Emission Spectrometer (L’TES) instrument acquired hyperspectral thermal infrared (TIR) observations of the Earth's Moon during Lucy's 2022 Earth gravity assist. L’TES covers the spectral range of 100–1,750 cm−1 (100–5.8 μm) at a spectral sampling of 8.64 cm−1 (Christensen et al., 2023, https://doi.org/10.1007/s11214‐023‐01029 ...

The Link Between Subsurface Rheology and Ejecta Mobility: The Case of Small New Impacts on Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract The dynamics of crater ejecta are sensitive to the material properties of the target, much like the crater size and morphology. We isolate and quantify the effect of target properties on the ejecta mobility (EM) ‐ the maximum radial extent of ejecta scaled by the crater radius.
