Science NewsScientists find how to prevent the world from asteroids Light bulb man Space and astronomy news 291 VIEWS 22 DECEMBER 2008 12345678910, the world's leading scientists are trying to find the best way to detect and prevent objects that float in space that might have crept into the public world. "We are looking for dangerous asteroid" James hit li (James Heasley) from the Institute of astronomy, University of Hawaii. Board of the National Science Council, the United States formed from the request of the Congress.Congress has asked the House of representatives continue to study after astronomers can't eliminate chance planet whose name APO fit (Apophis) will be crashed the world with mass destruction in 2579 (2036)APO fit were discovered in the 23 million-kilometer stage from 2547 (2004) world. In orbit that will overlap with the orbit of the Earth in the wok and 2572 (2029) back in again after 7 years. Observers said the asteroid is an enormous rock that occurred since the solar system was born. There are about 300 meters wide and heavy, at least 50 million tons.After additional gauges kansang Astronomers reported asteroid Moon may be almost gushing world there is no harm in it, but the chances are 1 in 2572 (2029) 44000 (0.002%) that crashed the world for East toe, which is Sunday, April 13 2579 (2036)To change the path, there are a few fit, it will be able to make it or not, all ethnic peoples all over the world. Diana Jin-ji Temple here (Jon Giorgini) on the planet more CAU-ra from the laboratory pressure jet propulsion of NASA. In Pasadena, California and dissemination update"We are not able to manage the issues. 2579 (2036)" li lin Johnson, Manager of asteroid detection plan for NASA. Board DirectorsSenate Committee led by suppliers win tea event Farnborough (Irwin Sharpiro) former Director of the Harvard Center for Astrophysics-Smith-Union thaso. In Cambridge. Mayor Sha Shu sates The task has been delegated from the Congress has 2 parts: detection of deviation and asteroids may have bumped all over the world.In the first stage. Board of tea will be offered intense event is the best way to detect and diagnose 90 per cent "of the object around the world" that orbit between Mars and Jupiter that are larger than 140 meters inside the 2563 (2020)Approximately 20 per cent of these object is specified as an object that has a serious danger because it might pass into stage 8 million kilometres from the Earth (20 times the distance from the Earth to the Moon)The number of objects near the Earth for more than 5,000 pieces. There are pieces that are identified as serious as threatened 789 pieces found Johnson predicted that future surveys will make this type of objects discovered at least harmful type of 66000 and 18000 pieces.The crashed object full of floating in the solar system is something that is unavoidable. Johnson said, "every year, there are 100 events this way, is already a concern, but it may happen tomorrow, they have," he said.For example, astronomers have just 24 hours to detect small asteroids that burn out over the skies of North Africa on October 7 in the past. An object that is larger than the more dangerous and need to be detected in advance for several years or ten years. So the man has enough time to prepare was crashed.The second task for the Board of tea is to investigate how intense the event that has been proposed to deviate the direction or destroy the asteroids that have crashed the world. And find out the best way possible. These methods include the use of nuclear bombs. General blasting or spaceship to push or pull the asteroid from the same direction.There are some strange, such as the painted surface of the asteroid so that it stores heat from the Sun is different from the original and changed direction to abduct or dragged by gravity, which is a satellite that will fly around asteroids and then gently pull it aside.The more dangerous asteroids have been detected much earlier, it is far from the world, and is much easier to change direction only. A little force, it will be possible to deviate the direction if it is far away, millions of kilometers.2572 (2029) will be a very important year. When APO fit moves through the world for the first time. Its path was specified precisely. This will allow astronomers to determine whether the world will avoid is very close or will need to be performed to avoid sudden crashed that can destroy a continent whose size is equal to the United States or Eastern Europe.The deviation of the direction of the asteroid. Scientists need to know the shape, weight, and composition of it. If it is yangkluang, we must deal with it differs from rocks, steel, tonnes."It looks like it's going to find success, but we must know our enemy," James Green. Planetary Science Division Director of NASA Said.Until now. NASA has used money to 41 million USD (approximately 1.4 billion baht) In order to detect the deviation and the asteroids, but all are close to the object map."It's taken some distress," he said. Event tea taro.To offer purchase expensive telescope 2 to look dangerous asteroids, but the Government and Congress of the reaffirmed need to convince is approved."If you don't buy a new camera to detect it is 90 percent" Johnson said.After many questions area Congress saw the importance in the project the asteroids from the testimony of Richard o boeman (Richard Obermann) Director of the Board's personnel sub about space and aircraft in the Council."Before it's comic opera" Council members said, "but it's now boeman is a survey required, very important," he said.Johnson said as the Board of Directors of the event go to the brilliant tea asteroids would have to come first."The plan is to throw away the heritage of mankind, rather than space to know time and location on the occurrence of destruction in outer space, so that we have time to prepare to cope with unavoidable events." He said.
