The Effects of ICME Composition on the Sputtered Component of the Lunar Exosphere

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Charged‐particle sputtering is a fundamental process that contributes to the generation of the Moon’s neutral exosphere. Neutral sputtering rates are dependent on the speed, flux, and composition of the incident charged‐particle populations, all of which are variable at the Moon’s orbit.

Ancient Impact Melt Near the Lunar South Pole: Distribution, Provenance, and Sampling Strategy

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Due to a lack of pre‐Nectarian samples associated with specific impacts in the Apollo suite, the early Solar System's impact chronology is poorly constrained. We investigate where Artemis and other south polar lunar missions could sample impactites to determine the ages of pre‐Nectarian craters, focusing on the ancient craters Haworth ...

Quantitative Evaluation of Shock Metamorphism in Clinopyroxene Using In Situ X‐Ray Diffraction Measurement of Lattice Strain

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Shock metamorphism is a ubiquitous process in our solar system. Shock pressure can be related to the lattice strain (ε) of individual minerals within a shocked sample. The lattice strain can be quantified within intact samples by in situ micro‐X‐ray diffraction (μXRD) using the Williamson‐Hall method. The Williamson‐Hall lattice strain (W‐H ε)

Galaxy clustering and dynamics from redshift surveys [PDF]

, 1990
The clustering and dynamical properties of the 368 galaxies in the redshift surveys of Metcalfe et al. (1989) and Parker et al. (1986) are investigated. These galaxies were selected from ten high galactic latitude fields complete to a magnitude limit of ...

Active Dust Devils in the Rosalind Franklin Rover Landing Site in Oxia Planum, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Rosalind Franklin rover will land in Oxia Planum, Mars, in the second half of 2030. The mission relies on solar arrays to provide electrical power to the rover, so knowledge about dust‐clearing rates is important for science operations.

Décollement Rheology Controls Crustal Deformation on Early Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The circum‐Tharsis wrinkle ridge system represents one of the strongest tectonic imprints of early Mars, formed as the planet's largest volcanic province reshaped the lithosphere and redistributed stresses across thousands of kilometers. The coherent spatial pattern of these ridges suggests deformation governed by a laterally continuous basal ...

Photochemical effects of Mars‐like UV irradiation on carboxylic acids in carbonaceous chondrites and expectations for abiotic background organics on Mars

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2445-2465, October 2026.
Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an

Description and terrestrial ages of the Calama Area Meteorite Collection (Atacama Desert, Chile)

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2415-2430, October 2026.
Abstract We present a comprehensive study of a meteorite collection from the Atacama Desert (Chile), the driest and most climatically stable desert in the world. This collection includes meteorites from three adjacent Dense Collection Areas (DCAs) in the northern part of the Atacama Desert: Calama, Sierra Gorda, and Chug Chug, referred to as the ...
