Planetary exploration of Mars has advanced rapidly in the past decade with high-resolution data from orbiting and landed instruments upending the image of a monotonously arid red planet and raising interest in a search for evidence of past or present Martian life. Cratered landscapes dissected by abandoned channels and active gullies, sedimentary sequences containing phyllosilicate and evaporate minerals, and plumes of atmospheric methane are tantalizing clues about the habitability potential for dynamic Mars. Plausible pathways and relative importance of biotic and abiotic processes during
