Future mission plans.<br /><br />EXOMARS seems fairly definitely committed to the 2011 time slot (MSL also seems to have slipped to this too) and was the subject of a number of papers on the proposed experiments. Some really nifty instruments have been developed, including a microOMEGA that brings OMEGA spectral capability at a 10-20 micro spatial resolution. There will be a 2 m drill on board as well, and a neutron probe and ground penetrating radar for subsurface survey. EXOMARS will land at between 45 degrees N and S, and will probably be altitude limited as well (limits not specified but MSL can’t land at altitudes of /> 2 km above datum, so EXOMARS is probably similar). The baseline mission is to study 10 sites, each 1 km apart, giving a travel of 10 km. Each site will be studied for 6-18 sols and provide 1Gb of data. A baseline site survey will consist of an area with a nominal 20 m radius. This will be the subject of a panoramic and subsurface survey. Ten locations will be selected for spectral and high-resolution imagery. Three of these will be subjected to contact science. Plus there will be hole drilled to 1.5 m for detailed analysis. At sites holes will be drilled to 2 m. A baseline of 30 samples can be analysed onboard.<br /><br />NASA astrobiology plans are to shift from the “follow the water” strategy to a “follow the carbon” goal over the next 10 years, this will lead into human precursor mission after this. There are definite plans for an astrobiology field lab to follow MSL. Five prime site types have been identified: those with aqueous sediments, those with fossil hydrothermal activity, those with ice, those with signs of present liquid water, and the north polar cap.<br /><br /> <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em> Arthur Clarke</p> </div>
