I've flown in space four times now, so it's going to be hard in that respect, but I certainly look forward to going back to Earth. I've been up here for a really long time and sometimes, when I think about it, I feel like I've lived my whole life up here.

And, obviously as a, as one who likes to travel around myself a lot, I think the Earth is a beautiful place. And, I'm looking forward to some new perspectives.

Now you're coming back to Earth, and things are getting more and more dynamic.

Retain the vision for space exploration. If we turn our backs on the vision again, we're going to have to live in a secondary position in human space flight for the rest of the century.

I have no desire to look back, I only want to look forward to the things that are still ahead of me.

Often have I wondered with much curiosity as to our coming into this world and what will follow our departure.

I never like to think about going back; I only look forward.

I hope to have more time to think, to look at the sky, dealing with less crisis management, to learn another language, to travel.

I'm really hopeful about the future of space exploration and human spaceflight. Civilization as we know it has been defined by exploration. You know, we need to go off and find out what's around the next corner and what's just beyond what we already know. It's part of our being; it's part of our moral fiber to go off and explore.
