Mars is a long ways away. The moon is only 240,000 miles, but Mars is in the millions. It's too risky without spending more time going to the moon.

Back in those days, going to the moon, geology was important, ... But how do we train pilots to be geologists? We concentrated on observing, not the analytical parts of the rocks.

I want to get to the moon. I want to go to Mars.

If you're going to go into space, you have to have an objective, a mission. Where do you want to go? Earth orbit? The moon? Mars? What's the technology to get there? You develop the technology for the mission.

We didn't slow down, unlike the others, when we got to the moon because we needed its gravity to get back, so we hold the altitude record. I never even thought about it. Records are only made to be broken.

I'm not particularly impressed with going 50 miles per gallon. That doesn't impress me when we can go to the moon.
