When Henry Ford made cheap, reliable cars people said, 'Nah, what's wrong with a horse?' That was a huge bet he made, and it worked.

If we drive down the cost of transportation in space, we can do great things.

I would like to die on Mars. Just not on impact.

The primary means of energy generation is going to solar. It will at least be a plurality, and probably be a slight majority in the long term.

It would take six months to get to Mars if you go there slowly, with optimal energy cost. Then it would take eighteen months for the planets to realign. Then it would take six months to get back, though I can see getting the travel time down to three months pretty quickly if America has the will.

America is the spirit of human exploration distilled.

You have to be pretty driven to make it happen. Otherwise, you will just make yourself miserable.
