Anything we can do in the near future that begins to stimulate the interest of people - seeing somebody down the street have an opportunity to go into space - buoys up the whole neighborhood.

There's no doubt who was a leader in space after the Apollo Program. Nobody came close to us. And our education system, in science, technology, engineering and math, was at the top of the world. It's no longer there. We're descending rather rapidly.

We could have human intelligence in orbit around Mars, building things there.

American greatness was elevated significantly after Sputnik.

No dream is too high for those with their eyes in the sky!

Certainly, I've never wanted to live on past achievements.

We have the ability, at such high fidelity, to simulate the physical world through computers. But when the spiritual world or human behavior comes into play, we don't have a very good model for that at all.
