Mars Science Laboratory Mission and Science Investigation
AbstractScheduled to land in August of 2012, the Mars Science Laboratory (MSL) Mission was initiated to explore the habitability of Mars. This includes both modern environments as well as ancient…
Mineralogy of a Mudstone at Yellowknife Bay, Gale Crater, Mars
Sedimentary rocks at Yellowknife Bay (Gale crater) on Mars include mudstone sampled by the Curiosity rover, indicating that clay mineral formation on Mars extended beyond Noachian time.
Serpentinization and its implications for life on the early Earth and Mars.
The petrology and mineral chemistry of an ophiolite-hosted cold spring in northern California is described and criteria to aid in the identification of serpentinizing terranes on Mars that have the potential to harbor chemosynthetic life are proposed.

Structural transitions in amorphous water ice and astrophysical implications.
The structural transition from Iah to Ial is responsible for the diffusion and recombination of radicals in ultraviolet-photolyzed interstellar ices at low temperatures and can be used to explain hitherto anomalous properties of astrophysical ices.
High-Density Amorphous Ice, the Frost on Interstellar Grains
Most water ice in the universe is in a form which does not occur naturally on Earth and of which only minimal amounts have been made in the laboratory. We have encountered this 'high-density…
X-ray Diffraction Results from Mars Science Laboratory: Mineralogy of Rocknest at Gale Crater
The Mars Science Laboratory rover Curiosity scooped samples of soil from the Rocknest aeolian bedform in Gale crater that revealed plagioclase, forsteritic olivine, augite, and pigeonite, with minor K-feldspar, magnetite, quartz, anhydrite, hematite and ilmenite, which are similar to that found on Earth in places such as soils on the Mauna Kea volcano, Hawaii.
Characterization and Calibration of the CheMin Mineralogical Instrument on Mars Science Laboratory
A principal goal of the Mars Science Laboratory (MSL) rover Curiosity is to identify and characterize past habitable environments on Mars. Determination of the mineralogical and chemical composition…
Mineralogy of an active eolian sediment from the Namib dune, Gale crater, Mars
The Mars Science Laboratory rover, Curiosity, is using a comprehensive scientific payload to explore rocks and soils in Gale crater, Mars. Recent investigations of the Bagnold Dune Field provided the…
Latitudinal distribution of black carbon soot in the upper troposphere and lower stratosphere
Black carbon soot from the upper troposphere and lower stratosphere has been systematically collected at latitudes from 90°N to 45°S. The measured latitudinal distribution of this soot at 10- to…
