    Astrobiologist Analogs Earth To Find Life On Mars

    February 16, 2021, Pilot Valley, Utah, USA: Astrobiologist KENNDA LYNCH examines brines, salts, and sediments in the Mars analog field site in Pilot Valley, Utah. Pilot Valley is a hypersaline paleolake basin that contains several aqueous minerals the have been detected on Mars. It also maintains a shallow groundwater system that hosts an amazing subsurface microbial ecosystem that includes perchlorate (a type of salt)-reducing bacteria. Her team studies the microbial ecology of the basin, and especially the perchlorate reducing bacteria, as an analog transitional habitable zone that could have occurred on Mars when surface water retreated in the Hesparian and groundwater became dominant again.
