Alternate oscillations of Martian hydrogen and oxygen upper atmospheres during a major dust storm

open access: yesNature Communications, 2022
Dust storms on Mars drive water escape to space. Here, the authors show the impact Martian dust storms have on the abundance of atmospheric hydrogen and oxygen, and how this helps to overall oxidize the Martian atmosphere.

Simulation of Transient Topside Layer in the Martian Ionosphere

open access: yesRemote Sensing, 2023
Many Mars missions, e.g., Mariner, Viking, Mars Global Surveyor (MGS), Mars Express (MEX), and Mars Atmosphere and Volatile Evolution (MAVEN), have been launched to study the Martian atmosphere.

Diurnal Variations of Water Ice in the Martian Atmosphere Observed by Mars Climate Sounder

open access: yesRemote Sensing, 2022
Simulation studies have proposed a significant thermal effect of water ice clouds on the Martian atmosphere and climate. However, previous studies focused more on seasonal variations but less on short-term changes.

Effects of Charged Martian Dust on Martian Atmosphere Remote Sensing

open access: yesRemote 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.

MAVEN Observations of the Interloop Magnetic Reconnections at Mars

open access: yesThe Astrophysical Journal, 2023
Magnetic reconnection between neighboring magnetic field loops, the so-called interloop reconnection, is a common process to drive flares in the solar atmosphere.

Mie scattering and the Martian atmosphere [PDF]

open access: yesSymposium - International Astronomical Union, 1971
It has been suggested that the discrepancy between radio occultation determinations of the Martian atmospheric surface pressure (3.8 to 7 mb) and those deduced from optical polarization measurements and a simple Rayleigh atmosphere model (about 10 mb) are the results of sub-micron sized aerosols in the Martian atmosphere.

Outgassing History and Escape of the Martian Atmosphere and Water Inventory [PDF]

open access: yes, 2015
The evolution and escape of the martian atmosphere and the planet’s water inventory can be separated into an early and late evolutionary epoch. The first epoch started from the planet’s origin and lasted ∼500 Myr.

Long-Endurance Mars Exploration Flying Vehicle: A Project Brief

open access: yesAerospace, 2023
The paper presents specifications for the Long-Endurance Mars Exploration Flying Vehicle (LEMFEV), which will be used as future design input data. The specifications are based on the analysis of previous Mars missions and scientific data collected by the
