I don't know what you could say about a day in which you have seen four beautiful sunsets.

I am a stranger. I come in peace. Take me to your leader and there will be a massive reward for you in eternity.

I think that it's good for us to be able to travel in space and do research in space, and I emphasize the research, because space travel to me is far more than just seeing how far we can go.

I still love to fly and I'll never get over that.

Zero G and I feel fine.

Just because I'm 77 doesn't mean I don't have a dream.

The moment of twilight is simply beautiful.
