Subsurface Structure and Morphometry of the Wrinkle Ridges in the Late Amazonian Volcanic Unit on Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Wrinkle ridges are widespread compressional tectonic features on Mars and are important records of the planet's global contractional history. However, their formation, evolution and subsequent modification by other geologic processes remain poorly constrained.

The Role of Magmatic Styles in Planetary Thermal Evolution Models

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Previous studies that investigated the effects of magmatism on the interior dynamics, in particular for Earth‐sized planets, suggest that magmatism leads to more efficient mantle cooling. However, the extent to which different magmatic styles influence the thermal evolution of planets, and in particular smaller rocky bodies, has not yet been ...

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 ...

Forecasting Continuum Intensity for Solar Active Region Emergence Prediction Using Transformers

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Early and accurate prediction of solar active region (AR) emergence is crucial for space weather forecasting. Building on established Long Short‐Term Memory (LSTM) based approaches for forecasting the continuum intensity decrease associated with AR emergence, this work expands the modeling with new architectures and targets.

HELIOS ‐ Highly rEliable Links durIng sOlar conjunctionS

Radio Science, Volume 61, Issue 8, August 2026.
Abstract During deep space missions, maintaining reliable communication between a spacecraft and Earth becomes particularly challenging during superior solar conjunctions, when the spacecraft passes behind the Sun relative to Earth. The highly ionized solar corona and solar wind create plasma inhomogeneities that severely affect radio signals, leading ...
