Determination of the Dynamic Angle of Repose of Lunar Regolith Simulants

Geosciences
The determination of the dynamic angle of repose (DAR) of lunar regolith simulants is essential for modeling material behavior during in situ resource utilization (ISRU) processes and lunar surface operations.

ELEMENTAL AND TOPOGRAPHIC MAPPING OF LAVA FLOWSTRUCTURES IN MARE SERENITATIS ON THE MOON [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
The detection of lunar lava flows based on local morphology highly depends on the available images. The thickness of lava flows, however, has been studied by many researchers and lunar lava flows are shown to be as thick as 200 m.

Automated Mineral Identification and Rock‐Type Classification of Lunar Mare Basalts Using SEM Images

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract We present an automated system for identifying minerals and classifying rock types in Apollo lunar mare basalts using scanning electron microscopy (SEM) imagery. Mineral segmentation is based on a U‐Net architecture, supplemented by two scale‐aware models designed to incorporate pixel size information.

Lunar Farside Samples Returned by Chang’E-6 Mission: Significance for Understanding the South Pole-Aitken Basin Stratigraphic History

The Astronomical Journal
The Chang’E-6 (CE-6) mission, launched by China on 2024 May 3, marks the first successful retrieval of samples from the farside of the Moon, specifically from the southern mare plain of the Apollo basin within the South Pole-Aitken (SPA) Basin.

The Moon’s Early Magmatic Activities: From the Perspective of Lunar Alkali-Suite and Mg-Suite Samples

Space: Science & Technology
This review places emphasis on ancient lunar nonmare igneous samples alkali-suite and Mg-suite. The material on mineralogy and petrology of the Mg-suite presented here draws from “Lunar samples” by Papike et al.

Alteration of a Mantle‐Derived Dunite Boulder in Jezero Crater, Mars

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract In 2023, the Mars 2020 Perseverance rover explored the youngest preserved deposits on the Western fan of Jezero crater, Mars: a field of meter‐scale boulders dispersed above the previously explored sandstone and siltstone units. Reflectance spectra of the boulders delineated two classes, one olivine‐bearing and one pyroxene‐bearing.

Martian Magnetotail Neutral Sheet Asymmetry Driven by Heavy Planetary Pickup Ions

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract In the induced magnetotail of Mars, the neutral sheet is an important channel for atmospheric ion escape, yet the role of heavy planetary pickup ions in shaping its geometry has been unclear. Using three‐dimensional hybrid simulations, we demonstrate that these ions induce a global neutral sheet asymmetry via mass loading.

Propagating Internal‐Tide‐Induced Wave Stresses Resolve Discrepancies in Ocean Surface Tide Energetics

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Ocean tides are a major energy reservoir in Earth's climate system, yet global tide models systematically fail to reproduce observed tidal energetics. This limitation arises because existing models do not adequately represent how tide‐generated internal waves in the deep ocean regulate ocean tide energy, accounting only for their initial ...

Lunar Volatile and Mineralogy Mapping Orbiter (VMMO): Viable Science from Lunar CubeSats

, 2021
The Volatile and Mineralogy Mapping Orbiter (VMMO) is a low-cost 12U CubeSat concept that was originally selected by the European Space Agency (ESA) as one of the two winners of the 2018 SysNova Challenge.
