Rusty Schweickart Quotations

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.

There's no accepted global policy on what to do about asteroid impacts.

An asteroid can literally destroy 80 or 90 percent of the species that are alive on Earth. These are big events. I mean, this is called extinction.

When you look at the origins and evolution of life on Earth, it's been severely affected by asteroid impacts through history.

By preventing dangerous asteroid strikes, we can save millions of people, or even our entire species. And, as human beings, we can take responsibility for preserving this amazing evolutionary experiment of which we and all life on Earth are a part.

Americans who read the papers or watch Jay Leno have been aware for some time now that there is a slim but real possibility - about 1 in 45,000 - that an 850-foot-long asteroid called Apophis could strike Earth with catastrophic consequences on April 13, 2036.

We're not passengers on Spaceship Earth. We're the crew.

I don't want people to spend their nights worrying about getting hit by asteroids. But I do want them to encourage their political leaders to invest in the insurance, which will allow us to prevent it from happening.

As a former Apollo astronaut, I think it's safe to say that SpaceX and the other commercial developers embody the 21st century version of the Apollo frontier spirit.

All of us know today the value of communications satellites, weather satellites, resources satellites, etc.

It would take an extremely large spacecraft to deflect a large asteroid that would be headed directly for the Earth.

Landing on the moon was a dream that millions of kids have had for hundreds of years.

Asteroids are deep-space bodies orbiting the Sun, not the Earth, and traveling to one would mean sending humans into solar orbit for the very first time. Facing those challenges of radiation, navigation and life support on a months-long trip millions of miles from home would be a perfect learning journey before a Mars trip.

The nice thing about asteroids is that once you've found them, and once you have a good solid orbit on them, you can predict a hundred years ahead of time whether there is a likelihood of an impact with Earth.

When you have an asteroid threatening Earth, it's uncertain where it's going to hit until the last minute; the decision to take action has to be coordinated by the international community.

It is fantastic to think that one day we may be able to access fuel, materials and even water in space instead of digging deeper and deeper into our planet for what we need and then dragging it all up into orbit, against Earth's gravity.

No government in the world today has explicitly assigned the responsibility for planetary protection to any of its agencies.

It is through science that we understand the world around us, and by understanding the world around us, we not only contribute to ourselves, our family, to our communities, etc. - you also contribute to the basic development and evolution of humanity.

We're sitting in a shooting gallery, with hundreds of thousands of these things whizzing around in the inner solar system. So it's just a matter of time.

But the question is, do I agree with it when it's 1-in-100, when it's 1-in-50, if it's 1-in-20. That is a policy question. At what probability do you begin to spend hundreds of millions or billions of dollars in order to do something?

There are always natural disasters and it always seems as though the preparation is somewhat less than adequate. But we have had a series of quite substantial ones here in the last year.

So I just let go with one hand, and just sort of swung around, looked at the Earth below and the black space above and the sun over my shoulder. And, I mean, it was this incredible, spectacular view.

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.

This whole issue of limits to growth, which provides a psychological, as well as a physical, cap on potential expansion of activity and awareness, has had a very depressing effect on many people.... I don't for a moment think that there's any concept which anyone's working with now which will be followed as a straightforward scenario. But the idea embodied in concepts such as space colonization or space industrialization, or availability of nonterrestrial resources, is fundamental, and it will change the way in which people look at the future.

You see the Earth as a bright blue and white Christmas tree ornament in the black sky. It's so small and so fragile - you realize that on that small spot is everything that means everything to you; all of history and art and death and birth and love.

We are now able to very slightly and subtly reshape the solar system in order to enhance human survival.

You almost wish you could turn off the COMM and just appreciate the deafening quiet.

As you pass from sunlight into darkness and back again every hour and a half, you become startlingly aware how artificial are thousands of boundaries we've created to separate and define. And for the first time in your life you feel in your gut the precious unity of the Earth and all the living things it supports.

From the moon, the Earth is so small and so fragile, and such a precious little spot in that Universe, that you can block it out with your thumb. Then you realize that on that spot, that little blue and white thing, is everything that means anything to you — all of history and music and poetry and art and death and birth and love, tears, joy, games, all of it right there on that little spot that you can cover with your thumb. And you realize from that perspective that you’ve changed forever, that there is something new there, that the relationship is no longer what it was.
