Mineralogical Mapping of Pyroxene and Anorthosite in Dryden Crater Using M³ Hyperspectral Data

Engineering Proceedings
This study investigates the mineral composition of the lunar Dryden Crater using Moon Mineralogy Mapper (M3) data. A RGB false-color composite reveals distinct pyroxene, anorthosite, and possibly spinel distribution patterns.

Global Silicate Mineralogy of the Moon from the Diviner Lunar Radiometer

Science, 2010
Lunar Reconnaissance The Lunar Reconnaissance Orbiter reached lunar orbit on 23 June 2009. Global data acquired since then now tell us about the impact history of the Moon and the igneous processes that shaped it. Using the Lunar Orbiter Laser Altimeter, Head et al.

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

Journal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Space Weathering–driven Coupled Loss of S and Fe from Troilite on the Moon

The Astrophysical Journal Letters
Space weathering of sulfides is a key mechanism for the sulfur and iron anomalies on the surfaces of the Moon and other airless bodies. However, the detailed pathway for how space weathering modifies S and Fe contents in iron sulfide remains poorly ...

Origin of Long‐Wavelength Variations in Crustal Thickness on Rocky Planets

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Long‐wavelength crustal thickness variations are observed on telluric planets, particularly on Mars and the Moon whereas Mercury appears to lack such variations. They may stem from two early‐stage positive feedback mechanisms that can emerge in stagnant‐lid planets.

Space Weathering Properties of Chang’e-6 Soils and Implication for Regolith Evolution of Young Lunar Maria

The Astrophysical Journal Letters
Lunar soil samples from young maria (formed 3.0 Ga) and higher than the ∼21% found in the Chang’e-5 soils from younger mare (∼2.0 Ga). However, our spectroscopic study reveals that the Chang’e-6 soils are well developed, with high maturity, weak ...

Controls on Solar Wind Entry Identified Through Wind–ACE Heavy‐Ion Diagnostics

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Solar wind (SW) entry into the magnetosphere occurs through several mechanisms, but their dependence on the properties of different ion species is unknown. We compare measurements from Wind‐STICS (magnetosphere) with ACE‐SWICS (L1) to test for any preferential entry between He2+ and SW heavy ions.

Mineralogical Characteristics of the Lorentz and Coulomb-Sarton Basins Reveal Early Magmatic Activity on the Lunar Farside

The Astrophysical Journal
Mg# (molar Mg/(Mg+Fe)) is a critical geochemical indicator for quantifying the evolution of the lunar crust, providing essential insights into regional compositional variability, crustal differentiation processes, and the crystallization history of the ...

Electron Shot Noise on a Current Biased Antenna

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The Parker Solar Probe (PSP) Fields Experiment (FIELDS) uses Radio Frequency Spectrometer (RFS) data and Quasi‐Thermal Noise Spectroscopy (QTN) to determine the temperature and density of electrons in the heliosphere. The FIELDS antennas typically operate with a negative bias current.

Petrogenesis of Chang’e-6 Basalts and Implication for the Young Volcanism on the Lunar Farside

The Astrophysical Journal Letters
Mare basalts from lunar farside are pivotal for unraveling lunar nearside-farside dichotomies and global thermal history. The Chang’e-6 (CE-6) mission conducted the first sampling from a young basaltic unit within the Apollo basin on the lunar farside ...
