Abstract

We present here results on the preservation of organics in highly oxidized rock materials and clay layers drilled from 0-6m-depth (Borehole-7) under the Mars Analog Rio Tinto Experiment (MARTE). This simulated a Mars robotic drilling mission at the RioTinto (Spain)[2, 5]. The RT represents an important analog of the Sinus Meridiani Mars Site, and an ideal model for a potential deep subsurface Martian biosphere including anaerobic chemoautotrophs and strict anaerobic methanogens (sustained by Fe and S minerals)[2, 4 ...
