Studying whether there's life on Mars or studying how the universe began, there's something magical about pushing back the frontiers of knowledge. That's something that is almost part of being human, and I'm certain that will continue.
But when I wasn't working, I was usually at a window looking down at Earth.
The experience of being in space didn't change my perspective of myself or of the planet or of life. I had no spiritual experience.
The view of Earth is spectacular.
I've spent my whole life not talking to people, and I don't see why I should start now.
It's no secret that I've been reluctant to use my name for things.
