A Quote by Carrie Nugent
The basic method to find asteroids hasn't changed much in hundreds of years. So asteroids in a telescope look just like stars with one exception: They move with time.

NEOWISE has two goals: One is to characterize asteroids, figure out how big and how bright they are, really basic information about these bodies; and we also find asteroids.
I'm extraordinarily passionate about the idea of asteroid mining in the future. Asteroids out there, we know them from those that have fallen on the Earth, there is a class of asteroids, sub-class of nickel/iron asteroids, which are 50,000 times more enriched than Platinum mines on earth.
Why are hemorrhoids called hemorrhoids and asteroids called asteroids? Wouldn't it make more sense if it was the other way around? But if that was true, then a proctologist would be an astronaut.
The best thing to do is to study these asteroids so we know the range of parameters we would have to deal with and also to find them so we have as much time as possible to prepare.
One of the reasons NEOWISE is so valuable is that it sees the sky in the thermal infrared. That means that instead of seeing the sunlight that asteroids reflect, NEOWISE sees the heat that they emit. This is a vital capability, since some asteroids are as dark as coal and can be difficult or impossible to spot with other telescopes.
The strongest signals leaking off our planet are radar transmissions, not television or radio. The most powerful radars, such as the one mounted on the Arecibo telescope (used to study the ionosphere and map asteroids) could be detected with a similarly sized antenna at a distance of nearly 1,000 light-years.
If you were to stand on an asteroid in the main belt of asteroids between Mars and Jupiter in our solar system, you might be able to see one or two asteroids in the sky, but they would be very far away and very, very small. So you wouldn't have this 'dodging through tons of rocks' business you get in the movies.
On the whole, asteroids tend to leave Earth alone. And day to day, there really isn't cause for most people to give them any thought. But despite being remote objects that most people have never seen, asteroids, and the threat they pose, come up an awful lot in popular culture.
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.
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.
There's a lot of cruelty going on all the time, and I'm not just talking about inter-human cruelty. I'm talking about whole species becoming extinct, asteroids hitting planets, black holes gobbling up stars.
Asteroids have hit the Earth millions of times. We can see them as shooting stars every night. When they get bigger, things get complicated. It is only a matter of time until a big one hits us. And since we can do something about it, we should.
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.
There are stars in the night sky that look brighter than the others, and when you look at them through a telescope you realize you are looking at twins. The two stars rotate around each other, sometimes taking nearly a hundred years to do it. They create so much gravitational pull there's no room around for anything else. You might see a blue star, for example, and realize only later that it has a white dwarf as a companion - that first one shines so bright, by the time you notice the second one, it's too late.
I'd like a telescope, but I probably wouldn't look at the stars that often. I'd definitely be looking into people's flats most of the time.
It is time to kickstart a new U.S. space transportation industry and time to spread that industry into space itself, leveraging our space station legacy to ignite imaginations and entrepreneurship so that we can move farther out, back to the Moon, out to the asteroids, and on to Mars.
