In the science fiction "body", in order to resist the invasion of the body and the earth was established the Planetary Defense Council (Planetary Defense Council/PDC), and in reality, the National Aeronautics and Space Administration (NASA) has also set up a a Planetary Defense Coordination Office (Planetary Defense coordination Office/PDCO), but not in order to cope with the aliens, but in dealing with the asteroid threat.
According to the British "Daily Mail" reported that the duties of the PdCo is the ability to call up all the space agencies to classify, monitoring, tracking in the earth's orbit asteroids, comets and other objects and to coordinate efforts between agencies and governments, to deal with any potential effects of threats, and by the national Science Foundation will provide support (NFS).
This means that PDCO can work with the U.S. Federal Emergency Management Agency (FEMA), the Department of defense and other United States, international institutions, proposed emergency plan.
The person in charge of the office is Lindley Johnson, his title is very powerful: Planetary Defense Officer (Planetary Defense Officer)!
Prior to this, he has been the director of the near Earth Asteroid (NEO) project.
Since 1998, NASA has found more than two and a small near Earth Asteroid objects, each year will add about 90%, of which 900 of the diameter of 1500 meters or more.
NASA hope to monitor those near 450 feet (137 meters) in diameter, but there is also a threat of near earth objects, and this part of the estimated 75% have yet to be found.
Last month, the United States federal budget for fiscal year 2016 distribution of 50 million U.S. dollars of near earth objects, laid the foundation for the establishment of the PDCO, while only about $4 million a year ago.
