Most estimates of the mortality risk posed by asteroid impacts put it at about the same risk as flying in a commercial airliner. However, you have to remember that this is like the entire human race riding the plane - it is one of the few risks that really could wipe us all out.

Once you've got the makings of a star, gravity draws leftover gas and dust into a giant swirling disk. The dust continues to stick together, clumping into rocky asteroids, which eventually become orbiting rocky planets. And voila: a solar system!
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.
With enough money and international coordination, we can push incoming asteroids out of Earth's path. We might even be able to bring back extinct animals in the lab. The problem really isn't scientific - it's cultural. We aren't yet able to coordinate ourselves as a global civilization to do something simple like bring food to a famine-stricken region. We can actually use current satellite technologies to predict where famine will strike next, but we can't get food there - usually for political reasons.
Our biggest threat is not an asteroid about to crash into us, something we can do nothing about. Instead, all the major threats facing us today are problems entirely of our own making. And since we made the problems, we can also solve the problems.
Sooner or later, we will face a catastrophic threat from space. Of all the possible threats, only a gigantic asteroid hit can destroy the entire planet. If we prepare now, we better our odds of survival. The dinosaurs never knew what hit them.
The shuttle tomorrow is truly like laying the last spike on the transcontinental railroad, only much more so. And whether or not we're going to see in in the next 10 or 20 years, there are people alive today who will see manufacturing in space from moon materials or from asteroids.
By 2025 we expect new spacecraft designed for long journeys to allow us to begin the first ever crewed missions beyond the Moon into deep space. So we'll start by sending astronauts to an asteroid for the first time in history. By the mid-2030s I believe we can send humans to orbit Mars and return them safely to Earth. And a landing on Mars will follow and I expect to be around in see it.
An asteroid or a supervolcano could certainly destroy us, but we also face risks the dinosaurs never saw: An engineered virus, nuclear war, inadvertent creation of a micro black hole, or some as-yet-unknown technology could spell the end of us.
"Sooner or later disasters such as an asteroid collision or a nuclear war could wipe us all out, But once we spread out into space and establish independent colonies, our future should be safe."
We no longer need to discuss whether or not it is safe – over a decade and a half with three trillion GM meals eaten there has never been a single substantiated case of harm. You are more likely to get hit by an asteroid than to get hurt by GM food.
There is a one-in-300 chance that Earth will be struck on March 16, 2880, by an asteroid large enough to destroy civilization and possibly cause the extinction of the human race. But, on the bright side, Prince could re-release his hit song with the new refrain 'We're gonna party like its twenty-eight seventy-nine.'
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.
Or so we don't think about how we're just vulnerable specks trying to survive on a violent, tumultuous planet, at the mercy of hurricanes and volcanoes and asteroids and terrorists and disease and a million other things. We concentrate on having little thoughts so we don't have BIG THOUGHTS. . . . You've got to ignore the one big truth - life is fatal.
As a scientist, I want to go to Mars and back to asteroids and the Moon because I'm a scientist. But I can tell you, I'm not so naive a scientist to think that the nation might not have geopolitical reasons for going into space.
todays the first anniversary of the asteroid hitting the moon. A year ago i was sixteen years old, a sophomore in high school.
A hybrid human-robot mission to investigate an asteroid affords a realistic opportunity to demonstrate new technological capabilities for future deep-space travel and to test spacecraft for long-duration spaceflight.
I always loved both 'Breakout' and 'Asteroids' - I thought they were really good games. There was another game called 'Tempest' that I thought was really cool, and it represented a really hard technology. It's probably one of the only colour-vector screens that was used in the computer graphics field at that time.
I only hope that we shall not wait to adopt the program until after our astronomers have reported a new and unsuspected asteroid moving across their fields of vision with menacing speed. At that point it will be too late!
The language itself is what gets me interested in writing. It's weird to me that words exist. Never a dull moment with words. They're a layer between our minds and the physical reality around us, obviously, but the layer seems like it's always in flux, like an asteroid belt, constantly moving.
If an asteroid is coming toward you, you don't have to blow it up. You just have to slow it down long enough for our country to rotate out of the way.
The chunks of comet Shoemaker-Levy 9 were so large, and were moving so fast, that each hit Jupiter with at least the equivalent energy of the dinosaur-killing collision between Earth and an asteroid 65 million years ago. Whatever damage Jupiter sustained, one thing is for sure: it's got no dinosaurs left.
This is the sort of book that justifies fatwahs. If WWIII occurred right now, we could die happy knowing Baxter would never write again. If a dinosaur killing asteroid was headed for Earth and I knew Baxter had another book coming up, I would campaign for letting the rock hit, since it is obviously the work of a benovelent deity trying to save us from another Titan.
But to carve the Grand Canyon, Earth required millions of years. To excavate Meteor Crater, the universe, using a sixty-thousand-ton asteroid traveling upward of twenty miles per second, required a fraction of a second. No offense to Grand Canyon lovers, but for my money, Meteor Crater is the most amazing natural landmark in the world.
Caltech honored me -- they named an asteroid after me. There's only two of them up there with names. One of them is Walter Cronkite. The other is Tommy Lasorda.
It would be great if we were on multiple planets, but I think that's unrealistic. Hawking says we have to be on multiple planets so an asteroid could come and you'd still have some humans left. It's a nice idea. It satisfies the multiple-eggs-in-multiple-baskets concept.
An asteroid could hit us at any moment. This is not - and also, the most successful kind of life on this planet is not us, it's microbes. They're the ones who greatly outnumber us, and may eventually destroy us.
We made and spent at least 10 million dollars. The thing is, we heard that the planet was going to end in 2012. We thought, We have got to spend this money before the asteroid hits.
And you know, talk about something else is falling from the sky. And that is an asteroid. What's coming our way? Is this an effect of perhaps global warming or just some meteoric occasion?
Democrats do have a historic race going. Hillary Clinton vs. Barack Obama. Normally, when you see a black man or a woman president an asteroid is about to hit the Statue of Liberty.
Luckily, there are some rocks left over from our earliest days, asteroids formed during our solar system's birth. Occasionally, some of them drop in on Earth, and when they do, they're called meteorites.
Asteroids have us in our sight. The dinosaurs didn't have a space program, so they're not here to talk about this problem. We are, and we have the power to do something about it. I don't want to be the embarrassment of the galaxy, to have had the power to deflect an asteroid, and then not, and end up going extinct.
As you may know, I'm the co-founder and co-chairman of an asteroid company called Planetary Resources that is backed by a group of eight billionaires to implement the bold mission of extracting resources from near-Earth asteroids.
If you get asteroids about a kilometer in size, those are large enough and carry enough energy into our system to disrupt transportation, communication, the food chains, and that can be a really bad day on Earth.
Mars could very well be a staging location for the resources of the asteroid belt. We have to learn how to get a payback somewhere, but it's beyond Mars that the real payoff will come from minerals.
I've said multiple times that the world's first trillionaire is going to be the person who exploits the resources of asteroids, the natural resources that are rare on earth and common on selected asteroids. So there are many different reasons you might want to go into space. You might want to spend your honeymoon on the far side of the moon.
We want to build colonies on the Moon, Mars, the Moons of other planets, and even nearby asteroids. We want to make space tourism and commerce routine.
Mars is the symbolic and totally stimulating next objective that could so dominate the next century's exploration efforts. From Mars, the resources of all the asteroids will become readily available.
Global warming, along with the cutting and burning of forests and other critical habitats, is causing the loss of living species at a level comparable to the extinction event that wiped out the dinosaurs 65 million years ago. That event was believed to have been caused by a giant asteroid. This time it is not an asteroid colliding with the Earth and wreaking havoc: it is us.
While we didn't know the dinosaurs personally, we do know that they were wiped out by an asteroid impact.
I agree that we should go back to the moon and on to Mars. We should treat all objects in the solar system, including comets and asteroids, as exploration targets.
Why do they call it an asteroid when it's outside the hemisphere, but call it a haemorrhoid when it's on the outside of your ass?
It would take an extremely large spacecraft to deflect a large asteroid that would be headed directly for the Earth.
On Friday the 13th, April 2029, an asteroid large enough to fill the Rose Bowl as though it were an egg cup will fly so close to Earth that it will dip below the altitude of our communication satellites. We did not name this asteroid Bambi. Instead, we named it Apophis, after the Egyptian god of darkness and death.
It is interesting to observe with what singular unanimity the farthest sundered nations and generations consent to give completeness and roundness to an ancient fable, of which they indistinctly appreciate the beauty or the truth. By a faint and dream-like effort, though it be only by the vote of a scientific body, the dullest posterity slowly add some trait to the mythus. As when astronomers call the lately discovered planet Neptune; or the asteroid Astr
American writers often say they find it difficult to write Superman. They say he's too powerful; you can't give him problems. But Superman is a metaphor. For me, Superman has the same problems we do, but on a Paul Bunyan scale. If Superman walks the dog, he walks it around the asteroid belt because it can fly in space. When Superman's relatives visit, they come from the 31st century and bring some hellish monster conqueror from the future. But it's still a story about your relatives visiting.
The chances that your tombstone will read 'Killed by Asteroid' are about the same as they'd be for 'Killed in Airplane Crash.'
The stars associated with the solar system, such as the planets and asteroids (and it should be remembered that the term star in Biblical usage applies to any heavenly body other than the sun and moon) would be particularly likely to be involved, in the view of the heavy concentration of angels, both bad and evil, around the planet Earth.
We can both prevent asteroid impacts and address climate change. It's not either-or.
Think about the strangeness of today's situation. Thirty, forty years ago, we were still debating about what the future will be: communist, fascist, capitalist, whatever. Today, nobody even debates these issues. We all silently accept global capitalism is here to stay. On the other hand, we are obsessed with cosmic catastrophes: the whole life on earth disintegrating, because of some virus, because of an asteroid hitting the earth, and so on. So the paradox is, that it's much easier to imagine the end of all life on earth than a much more modest radical change in capitalism.
