Maybe we should do it.
A friend of mine thinks the idea of landing humans on Mars is an unimaginative idea. He's got nothing against all the money that will be spent, but asks why can't it be spent on something more exciting -- like a city on the bottom of the ocean, for example? But Lileks says going back into space will be exciting:
I wonder if we can embrace a big idea again. The moon shot was nonpartisan – Kennedy dialed the number, Nixon talked to the astronauts. Politics stopped at the ionosphere’s edge; it was an American gambit. I’d like to think we can do that again. I want to watch the Moon Channel with my daughter in 2010.
