Well yes, if we stopped doing stupid things than we might be able to bear the cost of the trip. If we stopped doing stupid things...

But it's also a lack of will because we don't have a rival as formidable as Russia threatening to beat us to the punch. Well, at least not at the moment. Russia looks more and more like it has the desire to play the role again - the desire, but probably not the ability. And if that's true, there's always China. In fact I wouldn't be totally surprised if China's increasing interest in space were the thing that finally got Americans to Mars.

But failing that, what's going to get us to commit the resources to a risky mission like travelling to Mars? A trip whose only reward is first saying we've been there, and only down the road a few decades the ability to colonize it and mine its natural resources?

The only thing more powerful in the nation's mind than projecting military power is money...and maybe that will be enough to get us there....
