Controls on Iron‐Redox State in Martian Magmas Quantified by Mössbauer Spectroscopy, Colorimetric Wet Chemistry, and XANES Spectroscopy

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract To elucidate the relationship between oxygen fugacities (fO2) recorded in martian basalts and redox processes in the martian interior, superliquidus 100‐kPa furnace experiments on a composition similar to Humphrey (Adirondack basalt) were conducted at variable fO2 and temperature. Quenched glasses were analyzed by EPMA, Mössbauer spectroscopy,

Experimental Hypervelocity Dust Impacts in Olivine—Multiscale Insights Into Microcrater Shock and Melting Effects From Coordinated SEM/TEM Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The flux of solar system meteoroids is dominated by objects less than 1 mm in diameter whose impact effects play a major role in the space weathering of airless body surfaces. These effects remain poorly characterized with respect to their dependence on the range of impact speeds for meteoroids across the inner solar system.

Shortwave Infrared Microimaging Spectroscopy of the Martian Meteorites

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Until samples from the Martian surface are successfully brought to Earth, meteorites represent the only opportunity to perform laboratory analyses on Martian material. Microimaging spectroscopy of the Martian meteorite suite provides a valuable means to better understand infrared data collected remotely from the Martian surface. This rapid and

Mineralogical Classification of CRISM Hyperspectral Data Under Uncertainty With Hybrid Neural Networks

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Orbital remote sensing observations are a lynchpin of planetary science research. Hyperspectral infrared spectroscopy in particular is key for planetary mineralogical exploration, for example, CRISM for Mars, as this underpins our understanding of the distribution of specific lithologies and the geological process leading to their formation ...

Exploring Terrestrial Lava Tubes as Martian Analogs (I): Multi‐Analytical Study of Mineralization Processes in Cueva del Vidrio, La Palma (Canary Islands)

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The study of terrestrial lava tubes is essential for understanding geological processes occurring during volcanic activity on other planetary bodies, such as Mars. These processes lead to the formation of minerals analogous to those found on other planets.
