Comment Why not more MERs? (Score 2, Insightful) 210
Given how well the two MER rovers are working, why not just build a couple more of them and send them to different locations on Mars? Seems like right now it would be better to explore more areas and get a better overall view of the martian geology. Better to have a limited (from a science standpoint) presence on Mars than put all your eggs in a $2B basket, IMHO.
