Washington's Planetary Defense Coordination Office (Planetary Defense coordination office in will to near earth orbit of the asteroid and comet launched a search and it will cooperate with the relief agencies, joint research emergency contingency plans.
NASA said that the threat is not known at present, to determine the time, but in recent years, several asteroid approximation but can not make us alert to potential hazards. If a medium-sized or large asteroid hit the earth, will cause catastrophic impact throughout the world. It is generally believed that it was the comet that led to the extinction of the dinosaurs.
NASA's newly established Planetary Defense Coordination Office (PDCO), which belongs to its planetary science division, is regulated by the Scientific Mission Directorate in Washington. The office will identify any potential impact threats.
About 1500 near earth objects (NEO) are identified each year. Since its launch in 1998, the NASA sponsored search mission has identified more than 13500 near earth objects.
In close to 1 kilometers in diameter of the near earth objects, NASA has identified 90 of them, and began to look to the smaller size, about the size of the football field.
Planetary Defense coordination office is ready to further expand the current cooperation with the Federal Emergency Management Agency (FEMA) and the Department of defense, and other U.S. and international agencies to establish contact.
NASA is currently working with the European Space Agency asteroid impact and deflection assessment program to work together to study the direction of the change in the direction of dangerous objects, and the way to deviate from the earth's orbit.
In the discovery of any relevant threat, such as the upcoming near or hit the Earth Asteroid, the office will be issued a notice, and through the coordination of the development of contingency plans.
The new project is funded by the National Science Foundation (NSF).
Planetary Defense coordination office will be ready if the asteroid collision is unavoidable. In this case, NASA will provide the Federal Emergency Management Agency to provide impact time, location and consequences of such information, the latter will make contingency plans accordingly.
Discussions on the focus of the asteroid exploration program have been carried out for many years. In 2016, near earth objects and planetary defense projects will receive $50 million (about $) funding.
