Long and NASA, "NASA" and those astronomical other in the United States are working continuously and continuously scan the sky through telescopes radio that haunt and hunt any celestial body such as asteroids that can come close to the ground and bump into such meteorite that fell on the area " Ural "mid Russia last Friday corresponding to the fifth century of the month of February and the latest big explosion and about a thousand people were injured, according to Russian authorities.
Astronomer "Paul Chudas" Paul Chodas of office "Continue orbs near-Earth" for belonging to the Jet Propulsion Laboratory in Pasadena, Calif. NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, said that scientists expect fall of the meteorite awful lot like a meteor Russia last once every 100 years on average, and that the meteor Russian reached a diameter of about 17 meters long and weighed about 10 tons, and Born huge energy during collision land and atmosphere estimated energy resulting from the explosion of 500 tons of material, "TNT" TNT, and strange and unique also bumping this meteorite coupled with the approaching asteroid "2012 DA14" from the ground on the same day also arrived to a distance of critical land is the closest distance approaching the asteroid from the ground since the nineties of the past century ever since the project began, "the follow-up orbs near Earth," according to confirmed Project scientists, if we assume that this asteroid collision land destroyed a huge city, inflicting a major environmental disaster.
Scientists say "NASA" they did not Bmekdr Agency discovered asteroid "2012 DA14" Ten years ago, the modest scientific possibilities at the time, but in the current period can now Agency tracking such asteroids through radar advanced space has, according to NASA also the estimates scientists suggest to the possibility of a half a million asteroid is approaching the Earth and hard for the agency followed up carefully because of its small size, it is similar to the size of the meteorite Russian latter, but it is believed that the agency discovered so far about 95 percent of these asteroids with a diameter of about kilometers and one or more identified orbits in the sky, which can pose a great danger on the ground as if struck by God forbid.
Program is based "follow-up orbs near-Earth" to monitor any celestial body can be very close to the ground, whether an asteroid or guilty through astronomical telescopes terrestrial telescopes space orbiting the Earth outside the atmosphere, and scientists are working to estimate the mass, size and determine their orbits, Perhaps the most important radio telescope on earth is a telescope "Puerto Rico" radio, which has a diameter of 305 meters and which detects any celestial body approaching the earth with high accuracy and can scan a third of the sky every night.
All astronomical observations of asteroids carried out by astronomical observatories different as well as the observations made by amateur astronomers, it is assumed Send scientific report thereon to the observatory "planets small car" Minor Planet Center funded by the U.S. space agency "NASA" and managed by the Observatory "Smithsonian of Physics astronomical "Smithsonian Astrophysical Observatory of the International Astronomical Union, based in Paris, but due to poor funding this telescope, has funded agency" NASA "observatory budget simple $ 5 million USD at the University of" Hawaii "and called on the observatory name" Atlas "Atlas or also called also
According to scientists this system can be a NASA survey sky full per night and identify asteroids that reach a diameter of about 45 meters before about a week of hitting the Earth, is expected to develop radar more accurate so that it can monitor the asteroid by about three weeks of hitting the ground by the end of 2015, God willing, which is long enough to alert people to the risk of collision and face and then minimize losses as much as possible.
