Aluminum Phyllosilicate and Jarosite Formation Through Alteration of Reworked Al/Si‐Rich Volcaniclastic Sediments in Nili Fossae, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Aluminum phyllosilicates occur in 1–10s of km2 exposures of Noachian (∼3.7 Ga) rock across Mars and typically appear stratigraphically above Fe/Mg‐phyllosilicates. These units have been proposed to represent pedogenic basalt weathering sequences.

Features in the Visible Spectra of the Enceladus Particle Plume and E Ring: Potential Evidence of Organic Materials and/or Missing Sub‐Micron Particles

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Visible spectra of the Enceladus particle plume and E ring contain evidence for a change in spectral slope around 0.5 μm. This feature can be seen in data obtained by both the Visual and Infrared Mapping Spectrometer and Imaging Science Subsystem onboard the Cassini Spacecraft, and is consistent with the slope change seen in the surface ...

Signal Data Stream Parameters Passing Ionospheric Communication Links With Fading Caused by Natural Clutter Phenomena

Radio Science, Volume 61, Issue 8, August 2026.
Abstract This paper explores the impact of natural phenomena on signal data transmission across various ionospheric communication channels. The study focuses on three primary phenomena: meteor trails prevalent in the middle‐ and lower‐latitude ionosphere, bubble and plume structures observed around the equatorial ionosphere, and magnetic‐storm‐induced ...

ML‐EPM: A Machine Learning Model of Auroral Electron Precipitation Spectra Using Long‐Term DMSP Observations

Space Weather, Volume 24, Issue 8, August 2026.
Abstract Auroral precipitation plays a key role in coupling the Magnetosphere–Ionosphere–Thermosphere system by modifying ionospheric conductance, currents, atmospheric heating, and upper‐atmospheric dynamics. Leveraging 17 years of electron spectrum data from the Defense Meteorological Satellite Program (DMSP), we developed a Machine Learning‐based ...

Latitudinal Dependence of the Geomagnetic and Solar Activity Effect on Sporadic‐E Layer

Space Weather, Volume 24, Issue 8, August 2026.
Abstract Based on the global COSMIC occultation data, the latitudinal dependence of the geomagnetic and solar activity effect on the sporadic‐E (Es) layer is statically investigated. At middle geomagnetic latitudes, Es occurrence rates generally decrease with increasing solar activity, except during winter and spring in the Southern Hemisphere.
