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)

Probing Subsurface Properties With Mission Hardware: Lessons Learned From Artificial Impacts of Mars 2020

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Hardware released during spacecraft entry can generate hypervelocity impacts that provide unique constraints on planetary subsurface properties. During NASA's Perseverance descent, two tungsten cruise ballast mass devices (CBMD) and fragments of the cruise stage formed meter‐scale craters north‐west of Jezero crater, in one of the sinuous ...

A 400‐Year Antarctic Ice‐Core Perchlorate Record Reveals Variability in Stratospheric Chlorine Chemistry

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Perchlorate (ClO4−) in polar ice preserves past chlorine oxidation chemistry; however, multi‐centennial Antarctic ClO4− records and the mechanisms controlling their variability remain poorly constrained. Here, we present the first 400‐year (1616−2016) ClO4− record from an Antarctic ice core, revealing two regimes separated around 1980.
