Exobiology: Exploration In Gusev Crater, Missions, Mobility, Rover, Sampling

Scientific paper

Rover Mobility is a fundamental aspect of future missions to Mars: it provides access to specific locations of interest and, at those sites, enables systematic field work. In general, the questions that can be addressed are a function of the rover's range as will be exemplified here by a representative site of interest, Gusev crater. Because, on Mars as on the Moon, material has been excavated from various depths by impact craters, mobility allows the search for, and sampling of, material that can elucidate the stratigraphy of a region without visiting all the representative contacts. As such, mobility can in many cases replace the need to drill into the subsurface of Mars. This is particularly important in regions of special exobiological interest. The case of Gusev crater is considered because it is generally representative of the kind of sites that have a complex history of fluvio-lacustrine processes: such sites are of the highest priority for exobiology exploration. High priority goals are to understand past climate conditions, to identify sedimentary deposits, and to identify buried organic materials and potential microfossils.
