How many NEOs exist?
There are many more small NEOs than large ones. Astronomers estimate that there are approximately 1100 Near Earth Asteroids (NEAs) larger than 1 km in diameter, and more than a million larger than 40 m in diameter (the approximate threshold for penetration through the Earth's atmosphere). The largest NEAs are less than 25 km in diameter. There are probably many more comets than NEAs, but they spend almost all of their lifetimes at great distances from the Sun and Earth, so that they contribute only about 10% to the census of larger objects that strike the Earth, and probably less than 1% of NEOs less than 1 km in diameter.
Are any NEOs predicted to hit the Earth?
As of the end of 2004, astronomers had discovered more than two thirds of the larger Near Earth Asteroids (diameter greater than 1 km). None of the known asteroids is a threat, but we have no way of predicting the next impact from an unknown object. The count of known NEAs can be obtained daily from the NASA Program Office website at .

What is the risk of impacts?
We don't know when the next NEO impact will take place, but we can calculate the odds. Statistically, the greatest danger is from an NEO with about 1 million megatons energy (roughly 2 km in diameter). On average, one of these collides with the Earth once or twice per million years, producing a global catastrophe that would kill a substantial (but unknown) fraction of the Earth's human population. Reduced to personal terms, this means that you have about one chance in 40,000 of dying as a result of a collision. Such statistics are interesting, but they don't tell you, of course, when the next catastrophic impact will take placeónext year or a million years from now. The purpose of the Spaceguard Survey is not to improve these statistical estimates, but to find any individual rock that may be on a collision course.

Could the end of days truly be upon us? Members of the international elite – including the Illuminati – seem to think so, and have chosen the Ozark Mountain region of the United States to hide out from the apocalypse. The Conspiracy Theory team finds what appears to be construction on underground cities hidden in mountain caverns and tunnels, blocking off formerly public entrances with iron bars and heavy security. An apparent influx of banks in the rural region also seems suspect, but when they hear about round the clock construction on the biggest private house in America, reportedly built entirely of military grade materials and owned by a D.C. defense contractor, Jesse suspects something big may be happening here – just below the surface.
Underground Ozarks
Welcome to Underground Ozarks, a site all about urban exploration in the Ozarks area. You'll find information and pictures of abandoned places, sewers and drains, ghost towns, and more. If it's in the Ozarks area, or just close enough to drive to, and you're not supposed to go there... We'll get it on the site eventually.
At 72,000 square feet, a gigantic private residence being built south of Ozark is stirring plenty of talk.

All the speculation over its sheer size -- once completed, it will be considered one of the largest residential homes in the US and the fact that its being made of concrete has caused plenty of rumors to go around
Following a few days of excited build-up, Planetary Resources, a new space startup backed by heavy hitters including Larry Page and James Cameron, officially announced its plans to mine asteroids near Earth. At the Tuesday morning event, which took place at the packed Space Gallery in the Museum of Flight in Seattle, the company said it would launch phase one of its mission within two years and use the next decade just to identify resource-rich asteroids.

The company wants to access two types of resources: water and platinum metals.
Water and its constituent elements, hydrogen and oxygen, are “the best rocket fuel out there.” They would be able to supply NASA exploration missions, fuel private exploration missions, boost satellites, fuel space stations, support private colonization efforts, and fuel tugs that could be used to clean up space debris.

A gravity tractor (GT) is a spacecraft that deflects another object in space, typically a potentially hazardous asteroid that might impact Earth, without physically contacting it, using only its gravitational field to transmit the required impulse.[1][2] The tractor spacecraft could either hover near the object being deflected or orbit near it. The concept has the advantage that essentially nothing need be known about the mechanical composition and structure of the asteroid in advance.

Wouldn't it be possible someone could developed a kind of asteroid weapon system?
Some kind of swarm satellites positioned in the asteroid belt
Working together, using gravity assisted maneuvers to travel around the belt. Searching for candidates that just need that special little push, to send it flying towards a target on Earth, or even in space, taking out an enemy satellite. Everyone would clearly, as this thread, scream "that's a natural occurrence, and just a meteor/asteroid... bad luck". No one to blame but mother nature.
Pretty awesome weapon, don't ya think? But possible?
