A Quote by Rusty Schweickart

The frontier in space, embodied in the space colony, is one in which the interactions between humans and their environment is so much more sensitive and interactive and less tolerant of irresponsibility than it is on the whole surface of the Earth.
The frontier in space, embodied in the space colony, is one in which the interactions between humans and their environment is so much more sensitive and interactive and less tolerant of irresponsibility than it is on the whole surface of the Earth. We are going to learn how to relate to the Earth and our own natural environment here by looking seriously at space colony ecologies.
Food production has affected the environment more than any other activity humans have engaged in. Humanity devotes more land to food production than anything else - roughly a third of the surface area of the earth, much of which was once forest but has been converted by humans into farms or grazing lands.

Those who dream of the joys of living in a space colony should live in a space colony.
Mars is the next frontier, what the Wild West was, what America was 500 years ago. It's time to strike out anew....Mars is where the action is for the next thousand years....The characteristic of human nature, and perhaps our simian branch of the family, is curiosity and exploration. When we stop doing that, we won't be humans anymore. I've seen far more in my lifetime than I ever dreamed. Many of our problems on Earth can only be solved by space technology....The next step is in space. It's inevitable.
We are always in the space in-between... all the spaces where you are not actually at home. You haven't arrived yet.... This is where our mind is the most open. We are alert, we are sensitive, and destiny can happen. We do not have any barriers and we are vulnerable. Vulnerability is important. It means we are completely alive and this is an extremely important space. This is for me the space from which my work generates.
In 2009 I went up on the space shuttle. I was in space for 16 days and docked at the space station for 11 days. The entire crew did five space walks, of which I was involved with three of them. When you're doing a space walk, you always have a buddy with you. It's a very dangerous environment when you're doing a space walk.
I believe that the manned space program can engage the public by advancing the space frontier. Every next mission takes you farther out in space than you were before, either technologically or in terms of distance.
One problem with people is that as soon as they fill a space it's them you see and not the space. Large, desolate landscapes stop being large, desolate landscapes once they have people in them. They define what the eye sees. And the human eye is almost always directed at other humans. In this way an illusion is created that humans are more important than those things on earth which are not human. It's a sick illusion.
We have indeed been out in space, but some are under the illusion that we have been off Earth. In reality humans have never been off Earth. We have always been on a piece of Earth in space. We survive only as long as we can breathe the air of Earth, drink its waters, and be nourished by its foods. There is no indication that as humans we will ever live anywhere else in the universe. Place, too, is continuously being transformed but only within its own possibilities.
Private enterprise can never lead a space frontier. It's not possible because a space frontier is expensive, it has unknown risks and it has unquantified risks.
Between the fear that something would happen and the hope that still it wouldn't, there is much more space than one thinks. On that narrow, hard, bare and dark space a lot of us spend their lives.
So much of what we said sounded crazy, yet none of it was false... as if two theoretical physicists stood on stage to say that when we travel near lightspeed, we get younger than nontravellers; that a mile of space next to the sun is differnt than a mile of space next to the earth because the sun-mile space is curved more than the the earth-mile. Silly ideas, worth the admission price in smiles, but they're true. Is high-energy physics interesting because it's true or because it's crazy?
If you're going to lead a space frontier, it has to be government; it'll never be private enterprise. Because the space frontier is dangerous, and it's expensive, and it has unquantified risks. And under those conditions, you cannot establish a capital-market evaluation of that enterprise. You can't get investors.
Space expands or contracts in the tensions and functions through which it exists. Space is not a static, inert thing. Space is alive; space is dynamic; space is imbued with movement expressed by forces and counterforces; space vibrates and resounds with color, light and form in the rhythm of life.
The Next Generation Space Telescope, which will be located much further away from the Earth than the Hubble Space Telescope presently is, will also explore the infrared part of the spectrum.
