The best way to study Mars is with two hands, eyes and ears of a geologist, first at a moon orbiting Mars... and then on the surface.

The final frontier may be human relationships, one person to another.

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

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

When you're in a spacecraft, you need to know what things you can touch and what things you shouldn't touch!

The surface of the moon is like nothing here on Earth! It's totally lacking any evidence of life. It has lots of fine, talcum-powderlike dust mixed with a complete variety of pebbles, rocks, and boulders. Many pebbles, fewer rocks, and even fewer boulders naturally make up its surface. The dust is a very fine, overall dark gray. And with no air molecules to separate the dust, it clings together like cement.

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