　　It is understood that the Planetary Defense Coordination Office will be responsible for all of NASA's detection and tracking of work related to near-Earth objects, if that's what it takes, it will also work with other federal agencies, as well as other countries. Lindley Johnson of the leaders of the Office even has a very cool title: planetary defence officer.

　　In recent years, the United States Aeronautics and Space Administration to avoid Earth suffered a devastating, has stepped up its efforts, United National Nuclear Security Administration recently conducted a study on the use of nuclear weapons of the asteroid's orbit scheme.

　　United States Aeronautics and Space Administration said, if they and other international organizations are not able to leave the asteroid it orbits, the new Planetary Defense Coordination Office will help humans on Earth for emergency preparedness, will also issue a warning notice to those potentially affected areas, and to assist emergency response agencies such as the Federal Emergency Management Agency for work.

　　Lindley Johnson in the United States said at a NASA press conference: "it is obvious that planetary defence cooperation is formally established in the Office of United States Aeronautics and Space Administration to the detection of natural hazards, develop a sign of defense planning. "

　　In addition to new offices outside the leader, Lindley Johnson also is a near-Earth object program Executive, now it has become part of the new Office. United States Aeronautics and Space Administration have been identified every year approximately 1500 new near-Earth objects, the Agency thought they had found an 90% greater than 3000 feet or more of near-Earth objects.

　　Now, they want to be able to detect smaller, but still potentially dangerous near-Earth objects, they are about 450 feet in diameter or larger. About 75% of these near-Earth objects was still not found.

　　From United States officials of NASA's Science Mission Directorate John Grunsfeld said in a press release: "asteroid detection, tracking and protecting the Earth are United States Aeronautics and Space Administration and its partners in a major role. Although there is no known planetary collision threat, but 2013 car ya bin g Super Fireball and the recent Halloween asteroids are reminders that we should remain vigilant, and expressed concern about the sky overhead. "

　　According to United States Aeronautics and Space Administration said, in last month's federal budget, including the near-Earth object observations and Planetary Defense of $ 50 million, and in 2010, the budget of only US $ 4 million.
