Let’s face it, space is a risky business. I always considered every launch a barely controlled explosion.

Aaron Cohen, NASA Administrator

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.

Helen Sharman

When a place gets crowded enough to require ID’s, social collapse is not far away. It is time to go elsewhere. The best thing about space travel is that it made it possible to go elsewhere.

Robert A. Heinlein

Space travel is life-enhancing, and anything that’s life-enhancing is worth doing. It makes you want to live forever.

Ray Bradbury

The thing I’ll remember most about the flight is that it was fun. In fact, I’m sure it was the most fun that I’ll ever have in my life.

I don’t think the human race will survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I’m an optimist. We will reach out to the stars.

Stephen Hawking

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.

Seth Shostak

Don’t tell me that man doesn’t belong out there. Man belongs wherever he wants to go - and he’ll do plenty well when he gets there.

Wernher von Braun, Rocket Engineer

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.

William S. Burroughs

I think that somebody with the resources and innovation and the idea is going to come out of nowhere and come up with a successful space travel program.

Kevin J. Anderson

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

Buzz Aldrin

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.

Ben Parr

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.

Burt Rutan

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

Ray Bradbury
