Space Travel quote

The Earth is the cradle of humanity, but mankind cannot stay in the cradle forever.

KONSTANTIN TSIOLKOVSKY, attributed, Final Frontier: The Pioneering Science and Technology of Exploring the Universe

Space is for everybody. It's not just for a few people in science or math, or for a select group of astronauts. That's our new frontier out there, and it's everybody's business to know about space.

CHRISTA MCAULIFFE, December 6, 1985


All civilizations become either spacefaring or extinct.

CARL SAGAN, Pale Blue Dot

Those who came before us made certain that this country rode the first waves of the industrial revolutions, the first waves of modern invention, and the first wave of nuclear power, and this generation does not intend to founder in the backwash of the coming age of space. We mean to be a part of it--we mean to lead it. For the eyes of the world now look into space, to the moon and to the planets beyond, and we have vowed that we shall not see it governed by a hostile flag of conquest, but by a banner of freedom and peace. We have vowed that we shall not see space filled with weapons of mass destruction, but with instruments of knowledge and understanding.

JOHN F. KENNEDY, speech at Rice University, September 12, 1962

I'm sure the universe is full of intelligent life. It's just been too intelligent to come here.

ARTHUR C. CLARKE, IRC discussion at, November 1, 1996

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, The Daily Telegraph, October 16, 2001

A man who has been in another world does not come back unchanged. One can't put the difference into words. When the man is a friend it may become painful: the old footing is not easy to recover.

C. S. LEWIS, Perelandra

The stars will never be won by little minds; we must be big as space itself.



Tags: Robert A. Heinlein

Some say that we should stop exploring space, that the cost in human lives is too great. But Columbia's crew would not have wanted that. We are a curious species, always wanting to know what is over the next hill, around the next corner, on the next island. And we have been that way for thousands of years.

The time will come when man will know even what is going on in the other planets and perhaps be able to visit them.

HENRY FORD, Theosophist Magazine, February 1930

I believe that space travel will one day become as common as airline travel is today. I'm convinced, however, that the true future of space travel does not lie with government agencies -- NASA is still obsessed with the idea that the primary purpose of the space program is science -- but real progress will come from private companies competing to provide the ultimate adventure ride, and NASA will receive the trickle-down benefits.

BUZZ ALDRIN, Magnificent Desolation

We cannot predict the new forces, powers, and discoveries that will be disclosed to us when we reach the other planets and set up new laboratories in space. They are as much beyond our vision today as fire or electricity would be beyond the imagination of a fish.

ARTHUR C. CLARKE, "Space and the Spirit of Man"


Our flight must be not only to the stars but into the nature of our own beings. Because it is not merely where we go, to Alpha Centauri or Betelgeuse, but what we are as we make our pilgrimage there. Our natures will be going there, too.

PHILIP K. DICK, "The Android and the Human"

We will never be able to build enough spaceships. The demand is enormous.

RICHARD BRANSON, "Demand for Space Travel Is Out of This World", Bloomberg, July 6, 2017


This is Major Tom to Ground Control
I'm stepping through the door
And I'm floating in a most peculiar way
And the stars look very different today
For here
Am I sitting in a tin can
Far above the world
Planet Earth is blue
And there's nothing I can do
Though I'm past one hundred thousand miles
I'm feeling very still
And I think my spaceship knows which way to go
Tell my wife I love her very much

DAVID BOWIE, "Space Oddity"


To venture into space we must be strong-willed and determined. We must be fully committed to its exploration and discovery; space permits no half measures and is unforgiving of mistakes.

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

RAY BRADBURY, Playboy, 1996


Tags: Ray Bradbury

Mankind is drawn to the heavens for the same reason we were once drawn into unknown lands and across the open sea. We choose to explore space because doing so improves our lives, and lifts our national spirit. So let us continue the journey.

GEORGE W. BUSH, speech at NASA Headquarters, January 14, 2004


Tags: George W. Bush

We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win.

JOHN F. KENNEDY, speech at Rice University, September 12, 1962


Robots going places is not as exciting as humans going places. The only people clamouring for space launches to Mars to recover the wandering robot skateboard currently stuck in a sandtrap there are, well, the people who want to make it their android whore. And when your Martian explorer is not exploring any more because it's stuck in a sandtrap, it means you've sent a skateboard to do the job of a human.
