NASA tracks the asteroids that endangered Earth

Launched the U.S. space agency NASA Tuesday broad campaign among scientists and astronomy enthusiasts to help keep track of all the asteroids that may be approaching space of the land problem a threat to life on its surface, and to develop ways to protect the planet from these objects.This initiative comes in the framework of the "major challenges" launched by the White House, which is a set of ambitious goals at the national and international level.The project will be based tracking asteroids on the cooperation between specialists in multiple disciplines and NASA and other U.S. and international agencies, universities and amateur astronomy.A draft supplement to the draft NASA announced recently its intention to implement it, is serving dragging a small asteroid next to the Moon even going into orbit, and thus become available to send astronauts to the surface for study.The Assistant Director said the U.S. space agency Lori Garver "Our agency is working to monitor the asteroids that pose a threat to our planet, have been spotted so far 95% of these larger bodies, and we have to follow so that all monitoring work.""The big challenge lies in the monitoring of asteroids and determine what needs to be done in case one of them was a threat on the ground," referring to the importance of cooperation with "the public with the ability to innovate, and with amateur astronomers to contribute to a solution to this global issue."And swim in the solar system large numbers of asteroids, which was formed with formation of the solar system, which are of different sizes, some of which swim close to the planet.And managed by NASA so far from monitoring 95% of the larger asteroids, those that exceeds one kilometer in diameter, has contributed to a crash this surface-Earth asteroids Bandthar dinosaurs more than 65 million years ago.Scientists confirm that a crash of this asteroid is rare, and that the asteroids observed so far do not pose any risk of this kind.The U.S. Congress asked NASA in 2005 to monitor all asteroids with a diameter greater than 140 meters, which can collide with the Earth in the future and cause havoc.The agency estimated the number of asteroids that no more than one hundred meters in diameter and that swim around the sun in orbits adjacent to the Earth's orbit around the sun, with 25 alpha monitoring only 25% of them.And research related to condense asteroids since the fifteenth of February, when an asteroid passed along the planet, the same day a meteor fell 15 meters in diameter in Russia signed thousand injured and causing panic and wide.NASA is trying, despite the austerity policy in recent years, the development of a system capable of transferring small asteroids in space.It funded a project at the University of Hawaii called Atlas aims to create a monitoring system for asteroids with a diameter of 45 meters and alarm them a week before it approached the ground.The asteroids with a diameter greater than 150 meters can warn them three weeks ago by the Atlas system, which may come into effect in 2015.In the year 2012, launched by former NASA scientists institution bearing the name "P 612" aimed at the construction of the first space telescope belonging to the private sector and specializes in control asteroids and "the protection of mankind."
