The View from the Top of Husband Hill
chriscrick writes "After 14 months of climbing, the Mars rover Spirit has reached the summit of Husband Hill, 269 feet above the edge of the Martian plain. The panoramic view from the top is spectacular. According to lead scientist Steve Squyres, 'What field geologists typically do - and Spirit is a robotic field geologist - is you climb to the top of the nearest hill and take a look around so you get the lay of the land and figure out where you want to go.'"
what a great view, but what can we learn from it

How about if it turns out that the planets move outward over time, and new planets split off from the sun? Then eventually, Earth would move out to Mars' position, and Venus would be where we are, with that planet cooling off from it's volcanic uproar and shedding it's heat in time for the water vapor to condense into seas...and so on...
OK, science buffs, shoot down my theory. Science fiction fans, tell me which story you've read that has that premise. I'm sure somebody's thought of it before...
