Is Mars a Gift for the Scientist?

Mars has a very pristinely beautifully preserved, ancient, geomorphic record. On Earth today, such landscapes don't last too long because we have active plate tectonics. Mars's ancient geomorphic record goes back billions of years and it tells us a history of a far warmer, wetter past. If you could actually get geologists to the planet Mars and actually go in touch with rocks, I think we'd be there by now.
