Save the taxpayer's money by canceling the Ares 1 and V.

Timing has always been a key element in my life. I have been blessed to have been in the right place at the right time.

To move forward, what's required is a unified space agenda based on exploration, science, development, commerce, and security.

Unless we are able to commit to a permanent growing settlement [on Mars], then I don't think just going there with humans and coming back is worth doing. The expense of planning to come back is like the people who left Europe to come to America and then to turn around and go back to Europe, it really doesn't make any sense at all.

Mars could very well be a staging location for the resources of the asteroid belt. We have to learn how to get a payback somewhere, but it's beyond Mars that the real payoff will come from minerals.

Bravery comes along as a gradual accumulation of discipline.

The first human beings to land on Mars should not come back to Earth. They should be the beginning of a build-up of a colony/settlement, I call it a 'permanence'.
