Bravery comes along as a gradual accumulation of discipline.

When President Kennedy took office, I was in the midst of my education.

I think I need to continue to think and plan and marry all of the different things that we could do that make transportation in space from the earth to the space station, from the earth to the moon to space stations around the moon to visiting an asteroid.

Mars is there, waiting to be reached.

There should be an international lunar base. That is certainly doable.

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'.

Is the destiny of the human species to sit back and play with our mouse and computer and imagine, fantasize?
