Effects of Charged Martian Dust on Martian Atmosphere Remote Sensing

Remote Sensing, 2022
In this paper, the extinction property and optical depth of charged Martian dust at infrared band 3 THz–300 THz are studied using the Mie scattering theory.

Meteoric Metal Chemistry in the Martian Atmosphere. [PDF]

J Geophys Res Planets, 2018
AbstractRecent measurements by the Imaging Ultraviolet Spectrograph (IUVS) instrument on NASA's Mars Atmosphere and Volatile EvolutioN mission show that a persistent layer of Mg+ ions occurs around 90 km in the Martian atmosphere but that neutral Mg atoms are not detectable.

Impact sculpting of the early martian atmosphere. [PDF]

Sci Adv
Intense bombardment of solar system planets in the immediate aftermath of protoplanetary disk dissipation has played a key role in their atmospheric evolution. During this epoch, energetic collisions will have removed substantial masses of gas from rocky planet atmospheres.

The value of returning a sample of the Martian atmosphere. [PDF]

Proc Natl Acad Sci U S A
The elemental and isotopic abundances of major species in the Martian atmosphere have been determined, but analyses often lack sufficient precision, and those of minor and trace species are frequently not well known. Many important questions about the evolution and current state of Mars require the kind of knowledge that can be gained from analysis of ...

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.

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.

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.

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.

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.

Methodology of estimation the parameters permissible values of the aerodynamic and inertial asymmetry of the martian probe

Космические аппараты и технологии, 2023
A technique for estimating small permissible values of the parameters of the aerodynamic and inertial asymmetry of an unguided space probe in the rarefied layers of the Martian atmosphere is considered.
