Weathering of Martian Surface Rocks
1986The early 1960s marked the beginning of an extremely important trend in Martian investigation, i.e., exploration by space missions. From 1962 to 1976 more than a dozen spacecraft in the framework Mars, Mariner, and Viking space missions were launched, providing new and important data on the composition and structure of the Martian atmosphere and soil ...

A model of interaction of Phobos’ surface with the martian environment
Icarus, 2011Abstract We simulate space weathering of Phobos’ surface due to both sputtering by solar wind ions (H+ and He2+) and planetary protons, and surface material vaporization by micrometeoroids impact. Assuming an Iron-rich composition of Phobos’ regolith, we find that densities of neutral species (Fe, O, Al, Ca, Mg, Na) in the martian environment are in ...

Iron mineralogy of the martian surface with OMEGA spectrometer
2014 6th Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2014Goal of this paper is mapping the 1 μm from the OMEGA spectra in order to study the Martian iron mineralogy. This study is based on the results of Carrozzo et al. [1]. Goal of this paper is to map the 1 μm absorption signature in OMEGA spectra, in order to study the Martian mineralogy.

Mineral stability at the Martian surface
Journal of Geophysical Research, 1968Thermodynamic calculations of mineral stability fields under a range of predicted surface conditions for Mars indicate that goethite will be unstable except under the wettest and coldest parts (pH2O ∼ 10−6 atm, T < 200°K) of this range. If the planetary atmosphere is strongly reducing, as implied by some estimates of CO abundance, the measured water ...

Neutron environments on the Martian surface.
Physica medica : PM : an international journal devoted to the applications of physics to medicine and biology : official journal of the Italian Association of Biomedical Physics (AIFB), 2002Radiation is a primary concern in the planning of a manned mission to Mars. Recent studies using NASA Langley Research Center's HZETRN space radiation transport code show that the low energy neutron fluence on the Martian surface is larger than previously expected.

On the composition of martian surface materials
Icarus, 1967Abstract Observations were made of Mars with the birefringent interferometer. These observations when combined with spectra of the Sun show that Mars has an extremely strong band at 3.1 μ. This band is presumably produced by hydrated minerals on the surface of Mars.

Acoustic environment of the Martian surface
Journal of Geophysical Research: Planets, 2001Prompted by the Mars Microphone aboard the 1998 Mars Polar Lander, a theoretical study of the acoustical environment of the Martian surface has been made to ascertain how the propagation of sound is attenuated under such conditions and to predict what sounds may be detectable by a microphone. Viscous and thermal relaxation (termed classical absorption),
