House on Mars
I don't get it. Yes, I could understand it back in the days when we pictured Mars as a world of canals and exotic creatures, but now? Now that we know what all those places are actually like?
If you really want a house in the middle of a frozen, lifeless, dimly-lit wasteland where nothing ever happens and where you would immediately die if you stepped out of doors without elaborate protection, you can probably get one in Antarctica -- and for literally a millionth of the cost. I'm sure Saturn is an impressive sight from its nearer moons, but a single piece of scenery that never changes would pall eventually, and then what would you have? There's less to go out and do on a dead world than there is in the tiniest and dullest town in whatever country you live in, never mind Rome or New York or London or Tokyo.
Well, that's not quite true. There's one very worthwhile thing to do on other planets -- scientific research. And we're going about that the right way, by sending ever-more-sophisticated machines to do it for us, rather than sealing humans into large tin cans for a years-long voyage, at the end of which they would probably be in no psychological condition to spend further years collecting data.
But there are reasons why nobody wants a house in Antarctica.
