I'm happy here on the surface of the earth. If space travel ever got to be as simple as jet travel today, yeah, I'd take a jet flight to the moon.

Science does not just drive space travel - space travel also drives science.

I thought any chance I had of space travel would be military or government-controlled.

Growing up in the '60s and early '70s, with the space flight and the Apollo program, I always loved planes. I always loved rockets and I always loved space travel.

No one cares about race or religion or nationality in space travel. We're all just part of Team Human.

I believe the biggest impediment we have right now with going to Mars is public commitment. More people need to see themselves as a part of space travel; we need to see more inclusiveness.

I hope there will be continued U.K. investment in human spaceflight to enable Britain to benefit from space travel in the longer term and that many more Britons - women and men - will travel into space.

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

I think a lot of the American people feel more than a little disappointed that the high-water mark for human exploration was 1969. The dream of human space travel has almost died for a lot of people.

A zero-gravity flight is a first step toward space travel.

I think you're going to see an interest in space tourism, space travel for the sake of travel.

Look how far the human race has come in terms of air and space travel in the last hundred years. So in the next couple of thousand years, you've got to believe that we're going to be able to do all kinds of amazing things.

While human space travel is daunting, machines - with their indefinitely long lifetimes - could travel the galaxy. It might make little difference to them that bridging the distance from one star to the next could take hundreds of thousands of years or more.

The reason I wanted to do 'The First Men in the Moon' was that there is something so challenging in the combination of space travel and the Edwardian period.

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.

We need affordable space travel to inspire our youth, to let them know that they can experience their dreams, can set significant goals and be in a position to lead all of us to future progress in exploration, discovery and fun. Thanks to the X Prize for the inspiration.

I believe you'll see a low Earth orbit space travel business begin.

At the moment I'm doing this space movie, so I'm obsessed with physics and space travel. I know three months down the line it's gone. Then I'll be able to superficially say stuff about space.

Man is an artifact designed for space travel. He is not designed to remain in his present biologic state any more than a tadpole is designed to remain a tadpole.

We've gotta reinvest in space travel. We should've never left the moon.
