Bayesian Approach to Ionospheric Elementary Current Systems Using Differentiable Basis Functions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Spherical elementary current systems (SECS) have become a widely used tool to model vector fields on spherical surfaces in ionospheric data analysis. The systems were originally formulated using point sources for the divergence and curl of the fields. In this paper we present a flexible alternative formulation, showing how continuous functions

Exploring the Formation and Age of Irregular Mare Patches (IMPs) to the Southeast of the Chang'e‐5 Landing Site

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Recently, possible exceptionally young mare volcanic glass beads were discovered in Chang'e‐5 (CE‐5) samples. Isotopic dating suggests an age of approximately 120 Ma, presenting new challenges to existing lunar thermal evolution models. Thus, our research focuses on the source region of Rima Mairan, a branch of Rima Sharp, and its surrounding ...

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,

Characterization of Mercury's Atomic and Molecular Hydrogen Exosphere and the First Detection of H2 Ions

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract From 1974 to 1975, the Mariner 10 spacecraft studied Mercury's environment during three flybys and detected hydrogen, helium, and possibly atomic oxygen in the exosphere using its ultraviolet spectrometer, but no molecular hydrogen. Based on the sensitivity of the occultation instrument, an upper limit for the H2 ${\mathrm{H}}_{2}$ surface ...

Effects of Global Dust Storm in MY28 and Roles of Unresolved Waves on the General Circulation of Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The changes in the meridional circulation in MY28 owing to the global dust storm (GDS) event are quantitatively investigated using a reanalysis data set. During the GDS, a horn‐like high temperature anomaly up to 56 K relative to the climatology is observed around the north pole between 200 and 0.5 Pa.
