Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Determining marsquake magnitudes is essential for assessing seismic activity on Mars, yet previous estimates neglect three‐dimensional (3D) scattering effects. The exceptionally long‐lasting coda of the largest recorded marsquake, S1222a, provides a unique opportunity to quantify how crustal heterogeneities affect waveform propagation and ...

Remote Compositional Analyses of Space-weathered Lunar Maria
The Planetary Science JournalVisible-to-shortwave infrared (VSWIR) reflectance spectroscopy has revolutionized our understanding of planetary surface compositions. However, space-weathering processes on airless bodies complicate quantitative compositional analyses.

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

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 ...

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.

A Physics-Guided Diffusion Unmixing Model for Global Lunar Mineral Abundance Mapping
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingAccurate global mapping of lunar regolith minerals is critical for understanding the geological evolution and resource potential of the Moon. However, spectral unmixing algorithms originally designed for terrestrial remote sensing often perform poorly ...
