Exploring Mars is a far different venture from Apollo expeditions to the moon; it necessitates leaving our home planet on lengthy missions with a constrained return capability.

I think humans will reach Mars, and I would like to see it happen in my lifetime.

The biggest benefit of Apollo was the inspiration it gave to a growing generation to get into science and aerospace.

If we can conquer space, we can conquer childhood hunger.

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

Exploration is wired into our brains. If we can see the horizon, we want to know what's beyond.

I still say, 'Shoot for the moon; you might get there.'

Knowledge of the past and an optimistic view of the present give you great opportunities.

Many say exploration is part of our destiny, but it's actually our duty to future generations and their quest to ensure the survival of the human species.

Neil Armstrong was the first man to walk on the moon. I am the first man to piss his pants on the moon.

There may be aliens in our Milky Way galaxy, and there are billions of other galaxies. The probability is almost certain that there is life somewhere in space.

If I'll be funnier than this, I'll become a joke.

Endure every hardship as a discipline of grace.

Right is right even if no one is doing it

Things and conditions can give you pleasure but they cannot give you joy- joy arises from within.

The exhaustion of the passions is the beginning of wisdom.

I give the name violence to a boldness lying idle and enamored of danger.

I'm passionate about pleasing people.

I have had just about all I can take of myself.

Everything in food works together to create health or disease.
