I would say, in a decade or so, when the technology is more feasible & affordable, such an undertaking would be possible. Till then, the likes of spirit & opportunity (and other robots) are doing a great job! If money is usually the problem, there's always billions spent on developing a new bomb or armored vehicle every year you know...just sayin'.
