A distinct ripple-formation regime on Mars revealed by the morphometrics of barchan dunes

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.

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.

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.

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.

Evaluation of the Atmospheric Chemical Entropy Production of Mars

open access: yesEntropy, 2015
Thermodynamic disequilibrium is a necessary situation in a system in which complex emergent structures are created and maintained. It is known that most of the chemical disequilibrium, a particular type of thermodynamic disequilibrium, in Earth’s ...

Martian Bow Shock and Magnetic Pile-Up Barrier Formation Due to the Exosphere Ion Mass-Loading [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2011
Bow shock, formed by the interaction between the solar wind and a planet, is generated in different patterns depending on the conditions of the planet.

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

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.

Tianwen-1 and MAVEN Observations of the Response of Mars to an Interplanetary Coronal Mass Ejection

open access: yesThe Astrophysical Journal, 2023
Interplanetary coronal mass ejections (ICMEs) are solar transients that have significant effects on the upper atmosphere and ionosphere of Mars. The simultaneous spacecraft observations from Tianwen-1/MOMAG in solar wind and multiple instruments on board
