The Mars Topside Ionosphere Response to the X8.2 Solar Flare of 10 September 2017
Geophysical Research Letters, 2018 On 10 September 2017, irradiance from a magnitude X8.2 solar flare impacted Mars while the Mars Atmosphere and Volatile EvolutioN (MAVEN) orbiter was characterizing the Mars upper atmosphere.

Atmospheric processes affecting methane on Mars [PDF]
Icarus, 2022 It is currently uncertain as to whether methane exists on Mars. Data from the Curiosity Rover suggests a background methane concentration of a few tenths parts per billion whereas data from the Trace Gas Orbiter suggest an upper limit of twenty parts per trillion.

Martian Proton Aurora Brightening Reveals Atmospheric Ion Loss Intensifying
Geophysical Research Letters, 2023 The Martian proton aurora is a distinct aurora phenomenon resulting from the direct deposition of solar wind energy into Mars' dayside atmosphere. What solar wind parameters influence the aurora activity in the short term is yet unknown, as are the ...

Variability of Bow Shock Location at Mars [PDF]
Journal of Astronomy and Space Sciences, 1999 Bow shock formation, in case the supersonic solar wind flow is hindered by the atmosphere of Mars, is investigated. The atoms newly ionized from the extensive neutral atmosphere of Mars are loaded to the solar wind.

Sublimation of terrestrial permafrost and the implications for ice-loss processes on Mars
Nature Communications, 2019 Sublimation of ice is believed to have generated a variety of landforms on Mars and other planetary bodies. Here the authors show the first long-term in situ effective diffusion coefficient of terrestrial ice-free loess (Mars analog soil), scaled to Mars

Did high-energy astrophysical sources contribute to Martian atmospheric loss? [PDF]
MNRAS (November 21, 2016) Vol. 463 L64-L68, 2016 Mars is believed to have had a substantial atmosphere in the past. Atmospheric loss led to depressurization and cooling, and is thought to be the primary driving force responsible for the loss of liquid water from its surface. Recently, MAVEN observations have provided new insight into the physics of atmospheric loss induced by ICMEs and solar wind ...

Mars' atmospheric neon suggests volatile-rich primitive mantle [PDF]
, 2021 Martian atmospheric neon (Ne) has been detected by Viking and also found as trapped gas in Martian meteorites, though its abundance and isotopic composition have not been well determined. Because the timescale of Ne loss via atmospheric escape estimated from recent measurements with MAVEN is short (0.6--1 $\times$ 10$^8$ years), the abundance and ...

Earth – Mars Similarity Criteria for Martian Vehicles [PDF]
INCAS Bulletin, 2010 In order to select the most efficient kind of a martian exploring vehicle, the similarity criteria are deduced from the equilibrium movement in the terrestrial and martian conditions.
