Space travel for everyone is the next frontier in the human experience.

When you go to Mars, you need to have made the decision that you're there permanently. The more people we have there, the more it can become a sustaining environment. Except for very rare exceptions, the people who go to Mars shouldn't be coming back. Once you get on the surface, you're there.

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.

It's very exciting that people could actually live on another planet.

With every inch of land on Earth now catalogued by our satellites, the stars are the next place we as a species must travel. And with a booming world population that will hit 9.1 billion in 2050, large-scale space travel may become a necessity.

A trip to space is a big motivator to give up some things in your personal life. Obviously, you can't give up everything and you don't want to.

When I think back on it, it's amazing what happens to us as we move out into the world.

Travel for me is all about transformation, and I'm fascinated by those people who really do come back from a trip unrecognizable to themselves and perhaps open to the same possibilities they'd have written off not a month before.

Everyone who's been in space would, I'm sure, welcome the opportunity for a return to the exhilarating experiences there.

If people are given the opportunity to really make a difference in their own lives, their own communities, their own businesses and their own governments, then we can really transform the prospects of life on this planet. We can find ourselves living in a world that is more like the world that I think most of us want to be living in.
