Discovery of a wind-driven diamagnetic current system in the Martian magnetosphere [PDF]

Scientific Reports
Magnetic fields around Mars shape the pathways of energy input into, and ion escape from, the Martian atmosphere, thereby potentially affecting the atmospheric evolution of Mars.

Bow shock oscillations of Mars under weakly disturbed solar wind conditions [PDF]

Nature Communications
Bow shock, where the solar wind first encounters the Martian environment, reflects the complex interplay between the solar wind and Martian upper atmosphere and crustal fields.

Morphology of the Excited Hydroxyl in the Martian Atmosphere: A Model Study—Where to Search for Airglow on Mars?

Remote Sensing
Monitoring excited hydroxyl (OH*) airglow is broadly used for characterizing the state and dynamics of the terrestrial atmosphere. Recently, the existence of excited hydroxyl was confirmed using satellite observations in the Martian atmosphere.

Advective Fluxes in the Martian Regolith as a Mechanism Driving Methane and Other Trace Gas Emissions to the Atmosphere

Geophysical Research Letters, 2020
Advective fluxes influence methane and CO2 soil emissions into the atmosphere on Earth and may drive trace gas emissions in the Mars atmosphere. However, their relevance in the Martian regolith has not been evaluated to date.

Properties and models of the Martian bow shock

地球与行星物理论评, 2021
Mars does not have a global magnetic field of the internal origin, thus, the solar wind plasma can interact directly with the upper atmosphere and the ionosphere and be shocked with the mass-loading and magnetic pileup processes.

What Is the Radiation Impact of Extreme Solar Energetic Particle Events on Mars?

Space Weather, 2023
Solar Energetic Particles (SEP) are one of the major sources of the Martian radiation environment. It is important to understand the SEP‐induced Martian radiation environment for future human habitats on Mars.

Thermospheric density responses to Martian dust storm in autumn based on MAVEN data

Geodesy and Geodynamics, 2022
The unique seasonal surface dust storms on Mars have a significant impact on the Martian atmosphere. However, due to the lack of observations, semi-empirical models are difficult to simulate the density changes in the thermosphere with the existence of ...

Strong Depletion of 13C in CO Induced by Photolysis of CO2 in the Martian Atmosphere, Calculated by a Photochemical Model

The Planetary Science Journal, 2023
The isotopic signature of atmospheric carbon offers a unique tracer for the history of the Martian atmosphere and the origin of organic matter on Mars. The photolysis of CO _2 is known to induce strong isotopic fractionation of the carbon between CO _2 ...
