Part of me gets all thin-lipped and disapproving that we spend squillions of dollars to find out what other planets look like - oh, rocky and dusty, in the mean-time people are dying of hunger, etc.
The other part of me that thinks knowledge is a good in itself, is so impressed and admiring of the achievement - I didn't think it would work. Here we are, finding out how a world is made. Incredible.
I wonder if early science fiction writers who envisaged other planets as fabulous other worlds would be disappointed. My grandfather always liked it when discoveries of similarities and regularity were made across the universe. He used to see it as proof of God.
