ExoMars (Schiaparelli) mission scientists are now about to select the landing site, from an original list of 30 they must now select two or three potential sites. The criteria is detailed in the link below I know some here were disappointed that Curiosity did not go to Mawth however that mission was pure geology so Gale was perfect however Schiaparelli is looking for life past and present as well as some rock stuff.
Given the chance of a vote what would be your preferred landing sites? Me personally? Well I wouldn't mind having a crack at either of the 2 sites turned down by MSL i.e. Eberswalde Crater and Mawth Vallis the latter possibly being capable of preserving evidence of past and even present life only downside is the terrain might be a bit difficult.
