Experimental Constraints on the Formation of Niningerite and Oldhamite Under Highly Reducing Conditions: Implications for Sulfide Formation in EH3 Chondrites

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Enstatite chondrites record highly reducing conditions in the early solar nebula, yet the origin of their abundant sulfides remains unclear. Niningerite (MgS) and oldhamite (CaS) are ubiquitous in EH3 enstatite chondrites and distinguish them from other chondrite groups.

The Impact of Data Resolution on Planetary Compressional Structure Analysis

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Planetary studies of compressional structures are fundamental for understanding the tectonics and thermal evolution of planetary bodies. Compressional features are commonly characterized by their morphology, which in turn is strongly dependent on the spatial resolution of topographic data.

Currents in the Martian Ionosphere: Cases Without Strong Crustal Magnetic Fields

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract The Martian ionosphere hosts complex current systems driven both by solar wind interactions and neutral wind dynamo processes. While the global patterns of these current systems have been statistically examined, their detailed structures and orientations remain poorly constrained.

Characteristics of Lunar Surface Electrons Inferred From THEMIS‐ARTEMIS Observations: 2. Photoelectrons

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract The lunar surface charging is controlled mainly by the balance of electron currents near the surface. One of the main electron currents is the photocurrent on the dayside, comprised of photoelectrons produced by solar photons ionizing the lunar surface.

What Earth Erases: Weathering Diversity of Mineral Phases Formed in a Highly Reduced Environment Hosted in Aubrites

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Meteorites serve as an exceptional source of insight into our planet and the Solar System. Most meteorite fragments were recovered hundreds to thousands of years after their fall, and therefore exhibit varying degrees of terrestrial weathering, which has altered or completely removed weather‐sensitive mineral phases.

Minerals in Iron and Titanium Skeletal Textures in Nakhlites MIL 090030, MIL 090136, MIL 090032, and MIL 03346: Comparative Analysis With Terrestrial Analogues From Canary Islands, Spain

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract The presence of minor minerals is a key factor distinguishing meteorite types, as they provide valuable insights into the formation processes, surface conditions, and evolutionary history of their parent bodies. In Martian nakhlites, one of the most distinctive minor phases is iron‐titanium oxides forming characteristic skeletal textures ...

Quantitative Assessment of Geographic Control of December Solstice EIA Crest Shifts Over Southeast Asia Under Low Solar Activity

Space Weather, Volume 24, Issue 8, August 2026.
Abstract This study quantitatively assesses the drivers of the Equatorial Ionization Anomaly (EIA) morphology and latitudinal shifts over Southeast Asia during the December solstice. We use a 27‐year ionospheric data set (1998–2024) of total electron content (TEC) and F2‐layer peak electron density (NmF2) under geomagnetically quiet conditions.
