We must still think of ourselves as pioneers to understand the importance of space.

I suggest that going to Mars means permanence on the planet - a mission by which we are building up a confidence level to become a two-planet species.

Returning to the Moon with NASA astronauts is not the best usage of our resources. Because OUR resources should be directed to outward, beyond-the-moon, to establishing habitation and laboratories on the surface of Mars that can be built, assembled, from the close-by moons of Mars.

Somebody would think I was trying to get favored treatment because my ancestors had the name Moon. And that's a joke.

Bravery comes along as a gradual accumulation of discipline.

I was motivated to improve the U.S. strategy of going back to the moon in 1985. That's a long time ago. Going back to the moon would be a great achievement for tourism adventure flights.

I grew up in New Jersey and never went up the Statue of Liberty.
