Planetary Defense Quotes

For the first time in history, we have the chance to change the path of a celestial body. Let's realize what we're talking about here. We would be slightly changing the mechanics of our solar system to enhance our survival. That is gigantic!

Perhaps we need some outside, universal threat to make us recognize this common bond. I occasionally think how quickly our differences worldwide would vanish if we were facing an alien threat from outside this world.

I've often wondered, what if all of us in the world discovered that we were threatened by an outer -- a power from outer space, from another planet. Wouldn't we all of a sudden find that we didn't have any differences between us at all, we were all human beings, citizens of the world, and wouldn't we come together to fight that particular threat?

Since, in the long run, every planetary society will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring — not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive.

Space travel leading to skylife is vital to human survival, because the question is not whether we will be hit by an asteroid, but when. A planetary culture that does not develop spacefaring is courting suicide. All our history, all our social progress and growing insight will be for nothing if we perish. No risk of this kind, however small it might be argued to be, is worth taking, and no cost to prevent it is too great. No level of risk is acceptable when it comes to all or nothing survival.

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.

Newsreader: A huge asteroid could destroy Earth! And by coincidence, that's the subject of tonight's miniseries. Dogbert: In science, researchers proved that this simple device can keep idiots off your television screen. [TV remote control] Click.

I have been the last space marine between earth and an alien invasion. I really just don't need to go there anymore.

Buying insurance is no one's idea of fun. And it's especially easy to berate something as funky-sounding as writing checks to defend our neighborhoods against apartment-size rocks from space. But this is one insurance pitch that makes perfect sense. Ask the dinos.

Whether many people realize it yet or not, man, the Inferior Animal, has by now proved himself incapable of keeping his own species - and others - alive for very much longer. So the earth has begun its own plan to set things right.

We have heard the rationales offered by the nuclear superpowers. We know who speaks for the nations. But who speaks for the human species? Who speaks for Earth?

Are we going to let a space strike kill millions of people before we get serious about this?

Remember that movie Independence Day, where invaders were coming from outer space and the whole world was united against the invasion? Why can't we be united on behalf of our planet? And that's what I want to do.

After once having made the mistake of watching television news, I had worried for a while about an asteroid hitting the earth and wiping out human civilization. The anchorwoman had said it was not merely possible but probable. At the end of the report, she smiled.

There are thousands of asteroids whose orbit in the Solar System crosses that of Earth. And we have a little acronym for them - NEOs: near Earth objects. And our biggest goal is to try to catalogue them, so we know in advance if one is going to put us at risk.

In my Ph.D. thesis, written in 1989, I discussed the fact that when a civilization develops the technology to prevent catastrophic asteroid impacts, it marks a significant moment in the evolution of the planet.

People have to take seriously the threat coming from asteroids and what it represents. As Chelyabinsk reminded us, we have to take asteroids as a serious scientific concern, as well as a concern for protection of mankind and survival of the planet. This is not some kook policy. It's the protection of the interests of every single individual life on this planet.

Asteroid detection, tracking, and defense of our planet is something that NASA, its interagency partners, and the global community take very seriously.

Mars does not have an atmosphere and does not have a magnetic field today, so the planet doesn't have the protection from radiation that our atmosphere and magnetic fields provide us on Earth.

The number of people in the world engaged in this search for catastrophic impactors totals one or two dozen. How long into the future are you willing to protect Homo sapiens on Earth? Before you answer that question, take a detour to Arizona's Meteor Crater during your next vacation.

The nations of the world will have to unite for the next war will be an interplanetary war. The nations of Earth must some day make a common front against attack by people from other planets.

If we move toward the weaponisation of space, we can bid farewell to the planet. The chances of survival are very slight.

If we do our homework right, never again should an asteroid that can do damage on the ground impact the Earth. We're living in a time-with our technology-we have the capability to eliminate that major shaper of evolution . . . the evolution of life on this planet.

Consider that the overwhelming majority of those 40,000 near-Earth asteroids are small enough to fit on the parking lot at the mall. And while these rocky runts won't cause Armageddon, they could still flatten such popular hominid hangouts as Manhattan or downtown Des Moines.

What if an asteroid were to strike planet Earth? What could we possibly do to prevent it? However many guys we have working on this problem, it can't possibly be enough.
