Comparing Monte Carlo Models of Impact Alteration of Planetary Atmospheres

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract One process that affects atmospheric surface pressure is impact bombardment. The evolution of a planet's atmosphere under impact bombardment is an open question. We use a Monte Carlo method to evolve a range (0.006–92.5 bar) of initial atmospheres at Mars, Earth, and Venus under bombardment of 5×106 $5\times 1{0}^{6}$ impactors using seven ...

Ozone Detector Based on Ultraviolet Observations on the Martian Surface

Remote Sensing
Ozone plays a key role in both atmospheric chemistry and UV absorption in planetary atmospheres. On Mars, upper-tropospheric ozone has been widely characterized by space-based instruments.

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.

The Length of Martian Crater Rays and Their Relation to Lunar Cold Spots

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Impact‐generated crater rays are well‐documented on the Moon, with most appearing as high‐albedo streaks extending radially from a crater's center. On Mars, however, crater rays are significantly rarer and discernible only through thermal imaging due to their lower thermal inertia compared to surrounding terrain.

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 ...

Super‐Resolution of Planetary Images Based on Generative Adversarial Network

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Currently, satellite imagery serves as the primary means of observing terrestrial planets such as the Mars, the Moon, and Mercury. Enhancing the resolution and quality of these images can provide more detailed insights into planetary surfaces. However, improvements in image quality are often limited by the constraints of sensor technology and ...

Beyond the Electrostatic Approach: Numerical Simulations of Martian Ionospheric Irregularities

AGU Advances, Volume 7, Issue 5, August 2026.
Abstract Numerical simulations play an essential role in the study of ionospheric irregularities. In the past few decades, electrostatic simulations have successfully simulated the nonlinear evolution of terrestrial ionospheric irregularities. However, the Mars Atmosphere and Volatile EvolutioN (MAVEN) observations reveal that the Martian ionospheric ...

Acoustic Propagation in the Near‐Surface Martian Atmosphere

Journal of Geophysical Research: Planets
Abstract This work introduces a comprehensive model of sound propagation on Mars, in light of the recent operation of several microphones on the Martian surface. The main outcome of this work is an operational acoustic model capable of simulating the sound field created by any source, at any location on the ...
