I’m not a risk taker. But astronauts are professionals, so you get out on the field and play ball. I tried to take it in stride because that’s what I had to do to get into space. That’s where I belong, and I’m pretty good at it.

I have a great relationship with animals, and with children. I get to their level. I try to see the way a child looks at the world, it's hugely different.

Getting out of the comfortable path, that's what exploration is all about.

That I learned even as a three year-old that I see this world that is really a mess and I learned to say, this is not me. I am not the one that is messed up. It is out there.

Hubble touches people. When you're looking that far out, you're giving people their place in the universe, it touches people. Science is often visual, so it doesn't need translation. It's like poetry, it touches you.

Their spirituality was in nature, even though Emerson was a preacher on the pulpit, he ended up going out into nature for direct, face-to-face communication with God, if you want to call all of this creation part of God.

I'm such a long-term investor, I've never really let go and celebrated what I did with the Hubble telescope.
