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. It is found that the extinction coefficients of Martian atmospheric dust and the dust optical depth (DOD) of the Martian atmosphere can be amplified significantly as the dust particles are charged.

The Formation of the Martian Moons [PDF]

open access: yes, 2020
Abstract 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.

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.

Stability of the Martian Atmosphere [PDF]

open access: yesScience, 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.

Martian soil component in impact glasses in a Martian meteorite

open access: yesGeophysical Research Letters, 1999
Chemical compositions of impact melt glass veins, called Lithology C (Lith C) in Martian meteorite EET79001 were determined by electron microprobe analysis. A large enrichment of S, and significant enrichments of Al, Ca, and Na were observed in Lith C glass compared to Lithology A (Lith A). The S enrichment is due to mixing of plagioclase‐enriched Lith

Variations of the martian CO2 abundance with Martian season [PDF]

open access: yesSymposium - International Astronomical Union, 1971
All previous published equivalent widths of the Martian CO2 bands including the 1967 apparition coverage at McDonald Observatory are reduced to CO2 abundances using the same curve of growth parameters. The corresponding CO2 partial pressures (assuming a pure CO2 atmosphere), along with the regression curves of the north polar cap, are presented as ...

A Martian acoustic anemometer [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2016
An acoustic anemometer for use on Mars has been developed. To understand the processes that control the interaction between surface and atmosphere on Mars, not only the mean winds, but also the turbulent boundary layer, the fluxes of momentum, heat and molecular constituents between surface and atmosphere must be measured.

Fully inform the Martian [PDF]

open access: yesBJPsych Bulletin, 2015
At first glance, Reilly's thesis appears reasoned and structured.1 But his argument is flawed, such that he misses the most important reason for the distinction between psychiatry and neurology, with which a Martian would surely concur. Reilly states that ‘most organs (such as lungs, kidneys, hearts and eyes) are treated by a single medical ...

Water and the martian landscape [PDF]

open access: yesNature, 2001
Over the past 30 years, the water-generated landforms and landscapes of Mars have been revealed in increasing detail by a succession of spacecraft missions. Recent data from the Mars Global Surveyor mission confirm the view that brief episodes of water-related activity, including glaciation, punctuated the geological history of Mars. The most recent of
