LIBS Elemental Mapping of a Feldspathic Lunar Meteorite: Insights for In Situ Exploration

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract To meet the objectives of the many robotic and human missions planned for the Moon in the coming decade, new scientific instruments are currently under development. Laser‐induced breakdown spectroscopy (LIBS) is a robust technique for quantifying elemental abundances by focusing a pulsed laser to generate a plasma and collecting its emission ...

The Influence of Topography and Crustal Magnetic Anomalies on the Distribution of Water Ice in the Lunar South Pole Region

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Lunar magnetic anomalies are abundant near the south pole, where several moderate‐strength anomalies spatially overlap permanently shadowed regions (PSRs). This environment provides a unique setting to assess how crustal magnetic fields and topography regulate plasma–surface interactions and, in turn, the stability and distribution of surface ...

Quantifying Errors in the Midpoint Transform Applied to Oblique Ionograms

Radio Science, Volume 61, Issue 7, July 2026.
Abstract It is important to specify the state of the ionosphere for Over‐the‐Horizon communications and surveillance. Both vertical and oblique ionograms provide valuable data to this end. Oblique ionograms can probe the ionosphere in locations where it would be impractical to build a vertical ionosonde, but their measurements are not straightforward ...

Application of Deep Learning and Explainable AI to NIR Auroral Detection in Satellite Time‐Series Images

Space Weather, Volume 24, Issue 7, July 2026.
Abstract In this study, we employ a deep learning approach to detect auroras from near‐infrared (NIR) sequential images captured by the satellite‐based imager, the Enhanced Polar Outflow Probe (e‐POP)/Fast Auroral Imager (FAI). We also apply the Eigen‐Class Activation Map (Eigen‐CAM), an explainable AI technique in a broad sense, as a post‐hoc ...

Global Effect of Long‐Lasting 07–12 October 2024 Geomagnetic Storms During the Transition From a Strong (G3) to a Severe (G4) on the Geomagnetic Field and Ionospheric Parameters Distribution

Space Weather, Volume 24, Issue 7, July 2026.
Abstract This study investigates the co‐evolution of geomagnetic field disturbances with ionospheric parameters and their characteristic latitudinal signatures by conducting a location and time‐dependent analysis of the 07–12 October 2024 events, to fill crucial gaps in understanding the coupled response of the magnetosphere‐ionosphere system.
