Stability of perchlorate hydrates and their liquid solutions at the Phoenix landing site, Mars
[1] We studied the low-temperature properties of sodium and magnesium perchlorate solutions as potential liquid brines at the Phoenix landing site. We determined their theoretical eutectic values toExpand

The possible origin and persistence of life on Enceladus and detection of biomarkers in the plume.
The jets of icy particles and water vapor issuing from the south pole of Enceladus are evidence for activity driven by some geophysical energy source. The vapor has also been shown to contain simpleExpand

Low temperature aqueous ferric sulfate solutions on the surface of Mars
[1] We have studied the low-temperature properties of ferric sulfate Fe 2 (SO 4 ) 3 solutions as a model for potential liquid brines on the surface of Mars. Geochemical modeling demonstrates thatExpand

Experimental investigation of the stability and evaporation of sulfate and chloride brines on Mars
Abstract We have investigated the evaporation of concentrated magnesium and ferrous sulfate, and magnesium and ferric chloride brines as possible sources for liquid water on the surface of Mars, withExpand

Low pressure and desiccation effects on methanogens: Implications for life on Mars
Abstract Conditions on the surface of Mars would appear to be too hostile for life as we know it. But the subsurface is another matter. If liquid water is present, even intermittently, life formsExpand

Near‐ and mid‐infrared reflectance spectra of hydrated oxychlorine salts with implications for Mars
The presence and distribution of oxychlorine salts (e.g., chlorates and perchlorates) on Mars have implications for the stability of water, most notably, that they lower the freezing temperature. ToExpand

Mineralogical characterization of acid weathered phyllosilicates with implications for secondary martian deposits
Abstract The detection of phyllosilicates and sulfates on Mars has revealed a complex aqueous history which suggests distinct geochemical environments separated temporally and spatially. RecentExpand

Viscosity of liquid ferric sulfate solutions and application to the formation of gullies on Mars
[1] We studied the viscosity of ferric sulfate Fe2(SO4)3 solutions as a model for low-temperature liquids on the surface of Mars and their implication in the formation of gullies. Viscosity variesExpand
