I realized up there that our planet is not infinite. It's fragile. That may not be obvious to a lot of folks, and it's tough that people are fighting each other here on Earth instead of trying to get together and live on this planet. We look pretty vulnerable in the darkness of space.

...but since I realised that peace and freedom were unattainable on earth, my spirit aspired aloft, and everything that my chosen path required ceased to conflict with my conscience, because my conscience was calling me out into space, and was not much interested in what was happening on earth.

On a visit to the space program, President Kennedy asked me about the satellite. I told him that it would be more important than sending a man into space. “Why?” he asked. “Because,” I said, “this satellite will send ideas into space, and ideas last longer than men.

You have to think if we've been visited by extraterrestrial life, it was like a zookeeper walking into the chimp enclosure: He looks around, takes some pictures, then leaves without interacting significantly with the environment. Meanwhile the chimps have no idea what the fuck just happened.

Time does not give one much leeway: it thrusts us forward from behind, blows us through the narrow tunnel of the present into the future. But space is broad, teeming with possibilities, positions, intersections, passages, detours, U-turns, dead-ends, one-way streets. Too many possibilities, indeed.

You see, I cannot share my space with them. Not only am I severely claustrophobic but I abhor the mass. In general, I do not like people very much. Those I cannot sand are the average ones that eat with their hands out of plastic plates and travel in buses to work. I am horrified of them. "Mr. Wesley

The universe is not a stagnant place where technology stands still and only the few govern its destiny. Rather, it is a multidimensional dynamic entity that interacts with all things, even the very smallest. And what part we each place in it and the effect we have on it is a matter of our own choice.

Quiet moments bring you closer to God. It's your silent time within your own private sanctuary. People have so many things to talk about, worry about, think about, without giving themselves peace within. Quiet moments give you access to areas of your brain which allows you to function proficiently.

Everyone I have spoken with about working with the Russians in space exploration believes that the United States has learned a great deal from Russia and that Russia has learned a great deal from the United States – and that the entire international space partnership is much better because of it.

National boundaries are not evident when we view the Earth from space. Fanatical ethnic or religious or national chauvinisms are a little difficult to maintain when we see our planet as a fragile blue crescent fading to become an inconspicuous point of light against the bastion and citadel of the stars.

When I consider the small span of my life absorbed in the eternity of all time, or the small part of space which I can touch or see engulfed by the infinite immensity of spaces that I know not and that know me not, I am frightened and astonished to see myself here instead of there … now instead of then.

The storm long past, the night sky was beset with stars. Pointing upward, I asked her to pick a point of light and stay with it. Standing up, I eased Sara to her feet. Whispering into her ear, I asked, “Have you ever stood under a star... and felt the earth move under your feet?” - The Judas Syndrome

Hospitality means primarily the creation of free space where the stranger can enter and become a friend instead of an enemy. Hospitality is not to change people, but to offer them space where change can take place. It is not to bring men and women over to our side, but to offer freedom not disturbed by dividing lines.

In this single galaxy of ours there are eighty-seven thousand million suns. [...] In challenging it, you would be like ants attempting to label and classify all the grains of sand in all the deserts of the world. [...] It is a bitter thought, but you must face it. The planets you may one day possess. But the stars are not for man.

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.
