Petrologic constraints on the pressure, temperature, time and composition of the Martian interior [PDF]

open access: yes
Petrologic analysis of surface samples has been used to deduce pressure and temperature conditions existing in the crust and upper mantle at specific times in the Earth's history, as well as to estimate the chemical and mineralogical composition of the ...

Ozone Detector Based on Ultraviolet Observations on the Martian Surface

open access: yesRemote Sensing
Ozone plays a key role in both atmospheric chemistry and UV absorption in planetary atmospheres. On Mars, upper-tropospheric ozone has been widely characterized by space-based instruments.

Chalcophile Element Constraints on the Sulfur Content of the Martian Mantle [PDF]

open access: yes
The sulfur content of the Martian mantle is critical to understanding volcanic volatiles supplied to the surface of Mars and possibly climate. In the absence of Martian mantle rocks, sulfur content of the mantle has been inferred from S contents of ...

Martian surface weathering studies [PDF]

open access: yes
The nature of the Martian surface was characterized by means of its reflectance properties. The Mariner 9 photography was used to establish terrain units which were crossed by the Mariner 6 and 7 paths. The IR reflectance measured by the IR spectrometers

In situ mineralogical-chemical analysis of Martian materials at landing/roving sites by active and passive remote sensing methods [PDF]

open access: yes
Remote sensing of the Martian surface from the ground and from orbiting spacecraft has provided some first-order insight into the mineralogical-chemical composition and the weathering state of Martian surface materials. Much more detailed information can
