It bears mentioning that the Milky Way is only one of 150 billion galaxies visible to our telescopes - and each of these will have its own complement of planets.
There is a project that's underway called the interplanetary Internet. It's in operation between Earth and Mars. It's operating on the International Space Station. It's part of the spacecraft that's in orbit around the Sun that's rendezvoused with two planets.
The question we ask is - if there is life on other planets, should we expect it to be based on the same molecules, i.e. be universal - or should we expect it to depend on the local conditions, i.e. on the planet's geochemistry. So to find out, we try experiments on biomolecules, starting with such geochemistry conditions.
The photographs of space taken by our astronauts have been published all over the place. But the eye is a much more dynamic mechanism than any camera or pictures. It's a more exciting view in person than looking at the photographs. Of course, I personally am sick and tired of hearing people talk like that: I want to see it myself!
There are no wishy-washy astronauts. You don't get up there by being uncaring and blase. And whatever gave you the sense of tenacity and purpose to get that far in life is absolutely reaffirmed and deepened by the experience itself.
As an astronaut, especially during launch, half of the risk of a six-month flight is in the first nine minutes.
I left Aerospace because I wanted to go build, and put spacecraft together.
Age can be wonderful for red wine, but not for spacecraft.
I am absolutely certain that life can exist in outer space, move around, find a new aqueous environment.
Maybe the search for life shouldn't restrict attention to planets like Earth. Science fiction writers have other ideas: balloon-like creatures floating in the dense atmospheres of planets such as Jupiter, swarms of intelligent insects, nano-scale robots and more.
The images of Earth's delicate biosphere, contrasting with the sterile moonscape where the astronauts left their footsteps, have become iconic for environmentalists: these may indeed be the Apollo programme's most enduring legacy.
I stayed in the astronaut program until 1993. People ask me why I left. I thought I had a lot of things to contribute that would be difficult to do if I stayed. I thought I could have a stronger voice as an advocate for space exploration. So I ended up starting my own technology consulting company.
Rocket scientists agree that we have about reached the limit of our ability to travel in space using chemical rockets. To achieve anything near the speed of light we will need a new energy source and a new propellant. Nuclear fission is not an option.
Life can be less mysterious than we make it out to be when we try to think about how it would be on other planets. And if we remove the mystery of life, then I think it is a little bit easier for us to think about how we live, and how perhaps we're not as special as we always think we are.
I grew up watching a lot of the coverage of the early U.S. space program, all the way back starting with Mercury and then through Gemini and Apollo and of course going to the moon as the main part of the Apollo program.
Space offers extraordinary potential for commerce and adventure, for new innovations and new tests of will. As Americans, we can't help but reach for the stars. It's our nature. It's our destiny.
Most of our history in space has been communicated in terms of action - what people do, a chronological list of events which have transpired - as opposed to the human experience of having done those things.
If we ever start communicating with living creatures from other planets, the number one priority is, how are you going to communicate information? Even between different cultures here on Earth, you get into communication problems.
The world itself looks cleaner and so much more beautiful. Maybe we can make it that way - the way God intended it to be - by giving everyone, eventually, that new perspective from out in space.
I'm Chinese-American, of course, and so it's very interesting to see China actually launch their own astronauts, becoming the third nation, following the United States and Russia, to do so.
The sun and its retinue of planets drift as a group through the vast gulfs of space that separate the stars.
Thank you for the confidence put in my by the motherland and the people, for giving me this chance to represent China's millions of women by going into space.
Whether solid rockets are more or less likely to fail than liquid-fuel rockets is debatable. More serious, though, is that when they do fail, it's usually violent and spectacular.
To me, there is something superbly symbolic in the fact that an astronaut, sent up as assistant to a series of computers, found that he worked more accurately and more intelligently than they. Inside the capsule, man is still in charge.
The discovery and investigation of life on other planets is likely to change many of our ideas about how life arose on the Earth and even what is life and its natural development.
I don't think the space station is innovative. Going to the moon was innovative because we had no idea how to do it.
It would take an extremely large spacecraft to deflect a large asteroid that would be headed directly for the Earth.
We have the capability - physically, technically - to protect the Earth from asteroid impacts. We are now able to very slightly and subtly reshape the solar system in order to enhance human survival.
Those folks out in the space suits are going to be getting beat up.
Why is there space rather than no space? Why is space three-dimensional? Why is space big? We have a lot of room to move around in. How come it's not tiny? We have no consensus about these things. We're still exploring them.
It's very dangerous to put astronauts on a moon base where there's radiation, solar flares and micro meteorites. It'd be much better to put robots on the moon and have them mentally connected to astronauts on the Earth.
We want to make sure we get living astronauts to the surface of Mars.
Mars missions will require up to three years in reduced gravity, so we need to make sure astronauts can not only survive but thrive as they move outward to explore this new world.
We knew it was going to be difficult to get to the moon. We didn't know how difficult.
When you gaze at stars and think about planets, the places it takes your imagination are amazing! You look up the sky, and you know the stars have always been here; they were referenced in biblical times and have always been present. They are somewhere up there in the future, and they guide you; they make you feel safe.
I watched the moon landing as a boy, and I thought that was the most exciting thing ever, going into space, orbiting Earth and exploring other planets. That looked fantastic.
Put two ships in the open sea, without wind or tide, and, at last, they will come together. Throw two planets into space, and they will fall one on the other. Place two enemies in the midst of a crowd, and they will inevitably meet; it is a fatality, a question of time; that is all.
You build on failure. You use it as a stepping stone. Close the door on the past. You don't try to forget the mistakes, but you don't dwell on it. You don't let it have any of your energy, or any of your time, or any of your space.
If your ego starts out, 'I am important, I am big, I am special,' you're in for some disappointments when you look around at what we've discovered about the universe. No, you're not big. No, you're not. You're small in time and in space. And you have this frail vessel called the human body that's limited on Earth.
Technology is supposed to make our lives easier, allowing us to do things more quickly and efficiently. But too often it seems to make things harder, leaving us with fifty-button remote controls, digital cameras with hundreds of mysterious features and book-length manuals, and cars with dashboard systems worthy of the space shuttle.
Make space in your life for the things that matter, for family and friends, love and generosity, fun and joy. Without this, you will burn out in mid-career and wonder where your life went.
Between stimulus and response, there is a space where we choose our response.
Between stimulus and response there is a space. In that space is our power to choose our response. In our response lies our growth and our freedom.
Competitive golf is played mainly on a five-and-a-half-inch course... the space between your ears.
You live in the image you have of the world. Every one of us lives in a different world, with different space and different time.
Architecture is the art of how to waste space.
Everything is a learning lesson, good and bad, so I am happy with the way things are, and I learned from everything negative. I am in a great space now, so I wouldn't change a thing!
But a city is more than a place in space, it is a drama in time.
In awe, I watched the waxing moon ride across the zenith of the heavens like an ambered chariot towards the ebony void of infinite space wherein the tethered belts of Jupiter and Mars hang, for ever festooned in their orbital majesty. And as I looked at all this I thought... I must put a roof on this toilet.
Nothing exists except atoms and empty space; everything else is opinion.
I believe in Liberty for all men: the space to stretch their arms and their souls, the right to breathe and the right to vote, the freedom to choose their friends, enjoy the sunshine, and ride on the railroads, uncursed by color; thinking, dreaming, working as they will in a kingdom of beauty and love.
Music was my refuge. I could crawl into the space between the notes and curl my back to loneliness.
There is always space for improvement, no matter how long you've been in the business.
Space Mountain may be the oldest ride in the park, but it has the longest line.
There may be aliens in our Milky Way galaxy, and there are billions of other galaxies. The probability is almost certain that there is life somewhere in space.
In almost every profession - whether it's law or journalism, finance or medicine or academia or running a small business - people rely on confidential communications to do their jobs. We count on the space of trust that confidentiality provides. When someone breaches that trust, we are all worse off for it.
My father, Phillip Gilmore, was very talented. He was getting seriously into dancing. He was on 'Soul Train' and won $2,500. But the Bay Area was too small for him. I don't think he had the space to do what he needed to do.
Although the life of a person is in a land full of thorns and weeds, there is always a space in which the good seed can grow. You have to trust God.
What art offers is space - a certain breathing room for the spirit.
If we can conquer space, we can conquer childhood hunger.
