  • Habitability of Water-Rich Environments, Task 4: Evaluate the Habitability of Ancient Aqueous Solutions on Mars
    NAI 2013 Arizona State University Annual Report

    Co-I Farmer explored for past habitable environments on Mars as part of the MSL (Curiosity) team. He also participated in efforts to develop new life detection instruments for in situ astro-biological exploration of Mars, and documented lipid bio-signature preservation in siliceous hydrothermal deposits.

    Co-I Zolotov developed chemical weathering models for Mars. He argued that formation of salts and phyllo-silicates in the Noachian epoch was followed by aqueous mobilization and deposition of neutral salts in the Hesperian epoch. This hypothesis implies the occurrence of sulfate-saturated subsurface waters during a prolonged time after the formation of phyllo-silicates.
