Spatial and Temporal Extent of Plasma Depletion Events in the Ionosphere of Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has detected as many as 1,125 plasma depletion events (PDEs) in the Martian ionosphere from October 2014 to May 2021. PDEs, characterized by significantly reduced plasma density, elevated electron temperatures, and increased electrostatic fluctuations, remain poorly understood in ...

Infiltration Dynamics on Early Mars: Geomorphic, Climatic, and Water Storage Implications

Geophysical Research Letters
On early Mars, the integration of surface, groundwater, and climate systems into an integrated hydrological system remains poorly understood. The partitioning of precipitation, between surface and groundwater via infiltration, controls the Martian ...

Oblique impact: A process for providing meteorite samples of other planets [PDF]

Cratering flow calculations for a series of oblique to normal impacts of silicate projectiles onto a silicate halfspace were carried out to determine whether the gas produced upon shock vaporizing both projectile and planetary material could entrain and ...

Ancient Mars Climate With a Polar Ocean and Ice Sheet Dynamics

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract In this article, we study the conditions required to maintain a stable ocean on Mars 3 Ga using a new suite of simulations. These simulations couple a 3D Global Climate Model with ocean dynamics and ice sheet flow. The model includes the main processes of the atmosphere/hydrosphere/cryosphere to investigate Mars' ancient climate.

Aeolian removal of dust from photovoltaic surfaces on Mars [PDF]

It is well documented that Mars is totally engulfed in huge dust storms nearly each Martian year. Dust elevated in these global dust storms, or in any of the numerous local dust storms could settle on photovoltaic surfaces and seriously hamper ...

Laboratory Investigations of Flow Dynamics and Volume Growth During Erosion of Different Substrates by CO2 ${\text{CO}}_{2}$‐Driven Granular Flows in Martian Gullies

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Gullies are actively changing landforms on planet Mars. The prevailing hypothesis, supported by a suite of different studies, states that present‐day activity in these gullies is caused by fluidized granular flows driven by the sublimation of seasonal CO2 ${\text{CO}}_{2}$ ice.
