Near-Miss Asteroid Highlights Earth's Risk Of A Nuke-Sized CollisionThe asteroid 2012 DA14 which will come within about 17000 miles of Earth on February 15 is about half the size of a football stadium and in a collision would generate an explosive energy equivalent to 2500 kilotons of TNT. In comparison the atomic bomb over Hiroshima that instantly killed more than 70000 people released merely the equivalent of 17 kilotons of TNT. Seventeen-thousand miles seems like plenty of room but in cosmic terms it's an awfully close shave. Remember the Earth is a moving target traveling around the sun at 65000 miles per hour former astronaut Ed Lu said in a public appearance at the Stanford Institute for Economic Policy Research earlier this month. So [the asteroid] is missing us by only about 14 minutes.2012 DA14
highlights Earth's vulnerability to mid-sized asteroids capable of delivering nuclear-sized blasts.To be clear the asteroid is not going to collide with Earth. But if it did it'd have a devastating impact -- one that highlights Earth's vulnerability to a tough-to-detect mainstay of the cosmos: mid-sized asteroids capable of delivering nuclear-sized blasts. Comparable in size to the asteroid that destroyed 1000 square miles of trees and reindeer in Tunguska Siberia in 1908 2012 DA14 would be very bad news in a direct collision with a populated area. Imagine a giant explosion in the sky followed by a blast wave that would level buildings knock the Golden Gate Bridge into the sea and subject an area between San Francisco and San Jose to total destruction. A Spanish dental surgeon and amateur astronomer named Jaime Nomen first spotted 2012 DA14 last year â€Âœ- hence the 2012 in its name â€Âœ- so you might think that would give officials ample time to come up with an asteroid-deflection plan. But no. With one year's notice there's absolutely nothing we can do Lu said. There's no launch opportunity â€Âœ- the asteroid is orbiting back around the sun. Had it been coming back to hit us the only option would have been to evacuate. That's not a good option.The good news: With enough warning -- preferably decades -- an asteroid headed for Earth could be deflected. Ramming a remotely controlled spacecraft against an asteroid to change the velocity by just millimeters per second can avert a collision with Earth. If that is we have at least 10 years notice before a collision. With less time the change in velocity needs to be far greater. The curve goes from millimeters per second to meters per second pretty quickly Lu told Popular Science. The job rapidly goes from 'easy- easy' to almost impossible starting at about a decade. There are about one million asteroids larger than 40 meters that scientists consider near Earth objects because their paths around the sun criss-cross the Earth's orbit. NASA's near-Earth object office in Pasadena California reports that humans have spotted about 94 percent of the really large civilization-ending near-Earth asteroids â€Âœ in the 1- to 10- kilometer range like the monster that wiped out the dinosaurs 65 million years ago â€Âœ and concluded that none so far discovered will hit Earth in the next hundred years. But due to budgetary constraints Lu points out that we have identified the orbits of only 1 percent of the still potentially dangerous medium-sized asteroids of at least 40 meters â€Âœ like 2012 DA 14 or the Tunguska asteroid.Though amateur and professional astronomers on Earth have spotted the NEOs that we do know about there are limits to what terrestrial telescopes can accomplish. Telescopes only work at night which prevents us from seeing asteroids approaching the planet from the inside of Earth's orbit. Also many asteroids are dark black and reflect less than 10 percent visible light making them hard to spot from Earth. They do emit infrared light but many infrared wavelengths do not make it through the Earth's atmosphere.  Lu has raised several million dollars toward a final goal of roughly $400 million through his B612 Foundation to launch a telescope called Sentinel into orbit near Venus. During a proposed 6.5 year mission Sentinel will spot asteroids that cannot easily be identified from Earth. If successfully launched in 2018 Lu promises that Sentinel will spot about 500000 NEOs including 90 percent of all NEOs that are more than 140 meters and 50 percent of the Tunguska-sized 40-meter rocks. The only warning sign is a flash in the sky and a tidal wave.In making his fund-raising pitch Lu likes to compare the asteroid threat to the risks we face every day. Our planet has about a 30 percent chance of getting hit by a Tunguska- sized 40 meter asteroid in the next 100 years -- compare that to the 23 percent chance an American has of dying of cancer. There's about a 1 percent chance of getting hit by a 140-meter asteroid in the next century which would unleash the power of 100 megatons of TNT -- twice as large as the largest nuclear bomb ever exploded the Soviets' Tsar Bomba detonation in 1961. As a comparison a person has about a 1 percent chance of being killed in a car crash. And in the next 100 years there is roughly a .01% percent chance of getting hit by a 1-kilometer or greater asteroid that would destroy all of human life on Earth. A 1-kilometer and up asteroid would blanket the hemispheres with enough dirt and dust to destroy several years of food growing season leading to a Mad Max-like scenario in which survivors would quickly exhaust the world's three-month food supply. As a comparison any given American has about a .01% chance of dying in a plane crash. I think the governments of the world are very good at confronting a threat that is quantified: real time date place Lu says. When things are probabilistic? We're just not good at that.Lu compares the Sentinel project to a safety-precaution against a small but real threat of disaster like putting on a seat belt before driving. And he stresses that the asteroid problem can be easily handled â€Âœ- so long as we know where the asteroids are well in advance. If you don't know where they are the only warning sign is a flash in the sky and a tidal wave.Thank God!!! Our Clocks are about 14 minutes Faster :):)Let's get the giant space shuttle arm up there and chuck old satellites at them!A DAY WILL COME SOON ENOUGHALL THAT EVER LIVED ON EARTH WILL SOON HAVE THEIR EYES TO THE HEAVENSDo a little History on this one.ALL Should Look Up 2012 DA14.This could take out one of more satellites and the junk and debris from the hit could end up taking out many more satellites very soon after that. All the satellite collision probability will go way up if even one is hit. The velocity that the parts would go to would make them missiles that would start targeting a chain reaction this would not be good.Most all will be watching this one and pray it goes by us without a hit. Every Scientist alive will be watching this event. Many will be in Florida for a very special viewing of the once in a Lifetime Event. Professors Scientist World Leaders Ham Radio Operators and Every Astronomer will have its eyes on This Event along with almost every TV set on Earth.   2012 DA14 goes by Earth twice a year and there is no way anyone for sure can tell how close the second pass will be till it passes by the Moon and Earth and the GRAVITATIONAL FORCE effect that it will have on this Asteroid. They may come close but this one is already coming very close to begin with. Too close this time or on its second or 3rd pass? Ad a Meteor Shower like the 13 and 14 of December of  2012 it might go through or bump into one of them? Or all the other more then 2000 pieces of orbital debris like Spent Rocket Boosters left in space that can no longer be moved by a control center on Earth. Or add a Solar Flare. Or a Comet ISON or its tail debris of millions of rocks of all sizes. Not to for get the 30000+ pieces of space junk left from China in 2007 from showing the world it could shoot a decommissioned weather satellite in Space. Now add Asteroid 2013 BV15 into this on the 13 &14 of Feb 2013..Feb will have 12 of them from the 12 to the 16.If a big enough Asteroid were to slam into the moon in the night sky you would think the sun was coming up early only it would be 5 to 7 times as bright. From The Sun's Rays Reflection on all the Debris Field.2012 XM16 2012 XM55 2012 XP55 THERE ARE OVER 25 found just in the year 2012 that are part of the Near Earth Object Program that will come close to Earth from now till 2012 DA14 comes  Feb 14 - 16 2013.  You do not want to know how many are on the PLANETARY DEFENSE list.
The PLANETARY DEFENSE is not to protect Earth from men from Mars.
It is for all mankind with most all Nation in on it to stop if can most all collision with EARTH from a ASTEROID IMPACT.  It is if you will a AVOIDANCE SHIELD. N.E.O.S. Near Earth Object Shield.If only one were to hit or IMPACT EARTH on land get ready for a winter you will never forget. The winter from 1883 -1884 KRAKATOA you will think was a little pebble and now the stone comes. Krakatoa was a great mountain till it erupted with fire and a blast heard thousands of miles away that cast that Great Mountain into the sea. The Shock Waves were felt around the Globe. The sea was full of Bodies from the Tsunamis more then 35000 of them the sea stayed red for weeks. 1884 was a year without a summer as the year 1816 was and many world wide Froze to Death.A Shock Wave was felt in England from a Event about 7:15 to 7:20 A.M. Siberia time in the morning in June of the year 1908 high in the sky above the Forest in the remote wilderness of Tunguska Siberia heard an explosion that laid flat more than 800 square miles of the forest with all the trees pointing away from the center of the blast with most all the trees laying on their side. Some trees that were right below the blast were still there looking like telephone poles with no bark or branches left on them.  This Asteroid did not even hit the Ground and this is known by most as the TUNGUSKA EVENT.  For all that lived there it was WORMWOOD   Rev 8:11 the wood became full of worms and the rivers water no longer sweet and undrinkable.If a Meteor Shower is big enough you might think all the Stars are falling from Heaven. About one every 100 years makes it into the Earth’s Atmosphere big enough for all to take note.  Some make it to the surface the signs are all over the Planet and moon from the ones that have.   If you need a visual sign of a collided impact with a planet look to  SHOEMAKER - LEVY 9 July 1994.  You Need More Look up PROJECT WORMWOOD  Revelations 8: 10 - 11 based on the TUNGUSKA EVENT 1908 MOSCOW Russia is now saying it will use missiles to intercept Asteroid if need be. Better to be safe then sorry. GET READYRead your Bible
While you still can
and May our Lord GOD Bless all that do so.

Paul Felix Schott.December  2013 the Heavens above COMET C/2012 S1  ISON.The day will come whenALL ON EARTH WILL SEE THIS NO MATTER WHERE YOU ARE. the night side of earth will become day and and day will be blinding bright. The Bow Shock from the Photo Electric Effect from the Sun's Solar Wind will really be something.Shortly there after you will think the stars are falling from the HeavensREV 6:13 REV 16:21 most will be between 60 to 80 pounds that will make it to the ground surface. Nonstop 12 to 14 hours at a time for two days.P.S.
Help others in are Lord's name Jesus Christ help bring all to know him while you still can.Three kings that were wise men once flowed a star with a long tail 2000 years ago. That lead them to Jesus Christ wise men still look to and hear are Lord Jesus Christ.Question: Will pointing a laser at a meteor months away have any significant impact on it's trajectory?Why don't they send missiles up to practice a 'tractor beam' gravitational pull exercise to see if they can pull the asteroid off it's orbit and into the moon.  The fireworks would be amazing and clearly seen from the Earth!  Then too we would know the technique works and the practice would be invaluable for when the real thing comes around.Wasted opportunity!!Thxs Paul Felix Schott for the dose of crazy.@humanze yeah someone has a little too much time on their hands.my buddy's mother-in-law makes $72/hr on the computer. She has been without a job for ten months but last month her paycheck was $21863 just working on the computer for a few hours. Read more on this site
jump30.âžÂšomThe simple fact is meteors like this don't matter. Imagine a worst-case scenario - a direct hit on a population center (New York Bejing Tokoyo Paris Mexico City etc). Yes the U2 benefit concerts would never end and the world's economy would take a beating but while there would be some long lasting social consequences human population and industry on the planet would hardly blink.Unless it was a small country there would be little political impact and humanity would keep on going on with only minor changes in the life of a day-to-day person.It is like cutting a tree in a forest - soon replaced.Oakspar you're assertion appears to be that individual lives don't matter.  That is a dangerous position to take and that position taken by people in power has cost millions of people's lives just in the last century (Mao Stalin and Hitler to name the top 3). To bring it to the extreme take the 10 people you believe made the biggest difference in the world in the last century and imagine what the world would look like now without them.  Without Tesla we'd likely be using DC power and have to have substations every couple of miles. Without Einstein we'd not have GPS systems.  In the science category these are my top 2. You would not recognize the world in which they didn't exist.  All lives matter because unlike a tree in the forest they affect the world beyond the space they take up.Secondly what kind of sad geek to you have to be to say that a giant flaming ball falling from the sky doesn't matter?  It's freaking awesome! And that matters quite a  bit to me.You assume that with Tesla or Einstein that their discoveries would not have been found - first does not mean only and we undoubtably loose those kinds of leap ahead genious all the time to childhood disease or other causes.Since they did not arrive at their great conclusions we do not miss what they never did. Have you never had a great original idea only to find out that someone beat you to it?On the macro scale death only matters as a percentage of the population and as the population grows death - even mass death - becomes less signifigant. Consider the Black Plague's 75million death count. Very tramatic to society and civilization - that was a third of Europe. Today that would only be 1% of the world's population. Bad yes but hardly a plague.
