For the future, primarily, we must educate people in science, engineering, technology and math.

In Mars, we've been given a wonderful set of moons where we can send continuous numbers of people.

The beauty of Hawaii probably surpasses other places. I like the Big Island and the two mountains, Mauna Loa and Mauna Kea, where you can look out at the stars.

All the Chinese have to do is fly around the Moon and back, and they'll appear to have won the return to the Moon with humans. They could put one person on the surface of the Moon for one day and he'd be a national hero.

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

Retain the vision for space exploration. If we turn our backs on the vision again, we're going to have to live in a secondary position in human space flight for the rest of the century.

Most people never believed in the real possibility of going to the moon, and neither did I until I was in my twenties.
