Signs of Life in Meridiani Planum: What Might Opportunity See (Or Miss)?The Meridiani Planum hematite deposit has been designated as the prime landing site for Opportunity, one of the two Mars Exploration Rover (MER) spacecraft. Iron oxide and hydroxide minerals, including hematite, can mineralize and preserve microfossils and physical biomarkers. Previous research by ourselves and others, summarized below, has demonstrated such mineralization in a variety of terrestrial hematite deposits. Our most recent study has focused on the mineralization of microorganisms in rock varnish, the iron- and manganese-rich layers that coat rocks in many arid environments.
