I think I need to continue to think and plan and marry all of the different things that we could do that make transportation in space from the earth to the space station, from the earth to the moon to space stations around the moon to visiting an asteroid.

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

The future is about wings and wheels and new forms of space transportation, along with our deep-space ambition to set foot on another world in our solar system: Mars. I firmly believe we will establish permanence on that planet. And in reaching for that goal, we can cultivate commercial development of the moon, the asteroid belt, the Red Planet itself and beyond.

I felt pretty confident in relieving myself, since I had the urge.

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

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

If you want to say that the sky is black, and if I'm there, even if I fall back down again, I will be weightless for a period of time - maybe that's the definition of space.
