Thanks for the feedback guys, appreciate it.
nprev: you're right, that was one angle I was coming from. The MERs have given my generation its own Mars. Previous generations had the "Lowell Mars", of canals, vegetation and martians; the "Mariner Mars", a dead world of craters, volcanoes and mountains covered with the dust of millennia; the "Viking Mars", a world of emerging beauty and stunning geology. My generation has the "MER Mars", when we've discovered Mars to be a world far more dramatic and beautiful and complex and fascinating then we wver dared dream. My generation has, through the MERs, walked into craters, along ridges, up and down hills and across dune-rippled deserts, seen sunrises and sunsets in lavendar skies, and shooting stars skip across starry skies more perfect and clean than any seen on Earth. And Rui, you're right too: not a day goes by when I don't look at the images coming down from the MERs - and Odyssey, and MRO, and Express - and thank the universe that I live in a time when I can participate in the voyages of these new robot Magellans, Cooks and Darwins from the comfort of my own home, with a cat (see avatar left) curled up in my arm fast asleep. It is just, literally, magical.
But just for the record, no I wouldn't be happy if the MERs were some kind of "pinnacle of achievement for my generation". I want that to be putting men and women on Mars within my lifetime, preferably before the 2030s so I'm not so old I risk missing the historic first step because of a dash to the loo, when my bladder demands emptying for the tenth time in an hour...
