Stability of the Martian Atmosphere [PDF]

open access: greenScience, 1972
A detailed chemical dynamic model is presented for a moist martian atmosphere. Recombination of carbon dioxide is catalyzed by trace amounts of water. The abundances of carbon monoxide and molecular oxygen should vary in response to changes in atmospheric water and atmospheric mixing.

Microbes from Brine Systems with Fluctuating Salinity Can Thrive under Simulated Martian Chemical Conditions

open access: yesLife, 2021
The waters that were present on early Mars may have been habitable. Characterising environments analogous to these waters and investigating the viability of their microbes under simulated martian chemical conditions is key to developing hypotheses on ...

Clouds in the Martian Atmosphere [PDF]

open access: yes, 2021
Although resembling an extremely dry desert, planet Mars hosts clouds in its atmosphere. Every day somewhere on the planet a part of the tiny amount of water vapor held by the atmosphere can condense as ice crystals to form mainly cirrus-type clouds. The existence of water ice clouds has been known for a long time and they have been studied for decades,

Remembering the Forgotten Differences of Men and Women: A Comparative Study of Jordan Peterson’s debate, John Gray’s Men are from Mars, Women are from Venus and the Selected Quranic Verses

open access: yesالإيضاح, 2020
Gender differences and their depiction has been a rich debate for last few decades in Gender Studies. The current paper aims at exploring differences between men and women To begin with Jordan Peterson’s claim that men and women are not the same and ...

The Formation of the Martian Moons [PDF]

open access: yes, 2020
The origin of the natural satellites or moons of the solar system is as challenging to unravel as the formation of the planets. Before the start of the space probe exploration era, this topic of planetary science was restricted to telescopic observations, which limited the possibility of testing different formation scenarios.

Demonstrating Martian gravity [PDF]

open access: yesPhysics Education, 2015
The surface gravity on Mars is smaller than the surface gravity on Earth, resulting in longer falling times. This effect can be simulated on Earth by taking advantage of air resistance and buoyancy, which cause low density objects to fall slowly enough to approximate objects falling on the surface of Mars.

Progress and prospects for research on Martian topographic features and typical landform identification

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The study of Martian surface topography is important for understanding the geological evolution of Mars and revealing the spatial differentiation of the Martian landscape.

Is the Martian crust also the Martian elastic lithosphere? [PDF]

open access: yesJournal of Geophysical Research: Planets, 2002
Correlations between topography, gravity, and areoid on Mars are used to constrain the crustal and lithospheric thicknesses on the planet. Assuming that the Hellas basin is in isostatic equilibrium with Airy compensation, point correlations between areoid anomalies and topography are used to obtain the mean crustal density and the crustal thickness.

Seismic detection of the martian core [PDF]

open access: yesScience, 2021
Single seismometer structure Because of the lack of direct seismic observations, the interior structure of Mars has been a mystery. Khan et al. , Knapmeyer-Endrun et al. , and Stähler et al.

Surficial geology and geomorphology of Greg crater, Promethei Terra, Mars

open access: yesJournal of Maps, 2020
Greg crater, located in Promethei Terra, Mars is a ∼66 km diameter impact crater. The crater has been widely studied, both in terms of its overall geomorphological evolution and, more specifically, its ice-rich landforms.
