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.

The age of SNC meteorites and the antiquity of the Martian surface
Earth and Planetary Science Letters, 2005We report new Sm–Nd, Lu–Hf, and Pb–Pb mineral and whole-rock isotope data for the basaltic shergottite Zagami, as well as Pb–Pb whole-rock isotope data for the basaltic shergottite Los Angeles, the lherzolitic shergottite Dar-al-Gani 476 (DaG 476), and the clinopyroxenite Nakhla. In agreement with previous findings, our new Sm–Nd and Lu–Hf mineral ages

Orbital monitoring of martian surface changes
Icarus, 2016Abstract A history of martian surface changes is documented by a sequence of global mosaics made up of Mars Global Surveyor Mars Orbiter Camera daily color images from 1999 to 2006, together with a single mosaic from the Mars Reconnaissance Orbiter Mars Color Imager in 2009.

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 ...

Distribution of small channels on the Martian surface
Icarus, 1976The distribution of small channels on Mars has been mapped from Mariner 9 images at the 1:5,000,000 scale. The small channels referred to here are small valleys ranging in width from the resolution limit of the Mariner 9 wide-angle images (about 1 km) to about 10 km. The greatest density of small channels occurs in dark cratered terrain.

Digital Topography Models for Martian Surfaces
IEEE Geoscience and Remote Sensing Letters, 2005We propose to use an unsupervised automated classification of topographic features on Mars in order to speed up geomorphic and geologic mapping of the planet. We construct a digital topography model (DTM), a multilayer grid that stores various kinds of topographical information for every pixel in a site.

Lunar and Martian dust charging on surfaces
AIP Conference Proceedings, 2002The contact charging of two planetary analog dust samples are investigated in a simple experiment. Dust particles of lunar (JSC‐1) and Martian (JSC‐MARS‐1) regolith simulants are brought into contact with metals of known work function (Co, Ni, Au, Pt) and the resulting contact charge is measured.

Martian surface and crust: Review and synthesis
Icarus, 1973The nature of the classical marking of Mars are studied on the basis of Mariner 9 data and some earlier data. The analysis leads to a model of the Martian crust. Evidence for petrologic distinctions between surface materials in dark and light regions is obtained.

Magnetic Pulsations and Transients on Martian Surface
2020<p>InSight is the first Mars surface mission that includes a magnetometer, and one of the first discoveries made by the InSight FluxGate (IFG) magnetometer is the ultra-low-frequency (ULF) waves, or magnetic pulsations, on the Martian surface. By studying magnetic pulsations and transient signatures in more than six months of IFG

2008
Phenomenal new observations from Earth-based telescopes and Mars-based orbiters, landers, and rovers have dramatically advanced our understanding of the past environments on Mars. These include the first global-scale infrared and reflectance spectroscopic maps of the surface, leading to the discovery of key minerals indicative of specific past climate ...
