A Quote by Konstantin Tsiolkovsky
Man must at all costs overcome the Earth's gravity and have, in reserve, the space at least of the Solar System. All kinds of danger wait for him on the Earth. . . . We have said a great deal about the advantages of migration into space, but not all can be said or even imagined.

I hope that vigorous space exploration continues and that humankind will have a space station that resides between Earth and the moon. Outside the gravitational field of Earth, we could launch robotic spacecraft to other destinations in our solar system.
In the first place a philosophical proposition must be general. It must not deal specially with things on the surface of the earth, or within the solar system, or with any other portion of space and time. . . . This brings us to a second characteristic of philosophical propositions, namely that they must be a priori. A philosophical proposition must be such as can neither be proved nor disproved by empirical evidence. . . . Philosophy, if what has been said is correct, becomes indistinguishable from logic as that word has now come to be used.
When I was a kid, I was a bit of a space geek. I loved the space program and all things NASA. I would read books about our solar system; I had pictures of the Space Shuttle on my bedroom wall. And yes, I even went to Space Camp.
Man will not always stay on Earth; the pursuit of light and space will lead him to penetrate the bounds of the atmosphere, timidly at first, but in the end to conquer the whole of solar space.
What's aero braking? That's a way to use the gravity and upper atmosphere of Earth to sling shot a ship out either deeper into space, or slow it down to be 'captured' by Earth's gravity.
Right now I am a passenger on space vehicle Earth zooming about the Sun at 60,000 miles per hour somewhere in the solar system.
It is time to declare that the goal of the United States in space is the settlement of the solar system, from low Earth orbit to the Moon and Mars.
It is foolish to claim, as some do, that emigration into space offers a long-term escape from Earth's problems. Nowhere in our solar system offers an environment even as clement as the Antarctic or the top of Everest.
A new space race has begun, and most Americans are not even aware of it. This race is not about political prestige or military power. This new race involves the whole human species in a contest against time. All of the people of the Earth are in a desperate race against disaster... To save the Earth we must look beyond it, to interplanetary space. To present the collapse of civilization and the end of the world as we know it, we must understand that our planet does not exist in isolation.
Time is said to have only one dimension, and space to have three dimensions. ... The mathematical quaternion partakes of both these elements; in technical language it may be said to be 'time plus space', or 'space plus time': and in this sense it has, or at least involves a reference to, four dimensions. And how the One of Time, of Space the Three, Might in the Chain of Symbols girdled be.
We have one planet in our solar system that's habitable, and that's the Earth, and space travel can transform things back here for the better. First of all, by just having people go to space and look back on this fragile planet we live on. People have come back transformed and have done fantastic things.
I think I need to continue to think and plan and marry all of the different things that we could do that make transportation in space from the earth to the space station, from the earth to the moon to space stations around the moon to visiting an asteroid.
The secret of our success on planet Earth is space. Lots of it. Our solar system is a tiny island of activity in an ocean of emptiness.
The first space walk, it's really got your attention. You know you're travelling eight times faster than a rifle bullet, and you're outside. Second space walk, you're a lot more relaxed, you're looking over your shoulder, admiring the view of Earth. What was funny about the third space walk was that mission control in Houston called and said, "Take a moment and enjoy the view".
My job in space will be to observe and write a journal. I am also going to be teaching a class for students on earth about life in space and on the space shuttle and conducting experiments.
