From the asteroid will save only prayer


Mankind does not have the technologies capable of flying to reject a large asteroid to Earth, confident NASA. Agency head Charles Bolden answered questions of the scientific committee of the U.S. House and advised to pray to if the asteroid is three weeks.


The reason for the hearings are a few approaches of large objects with the Earth, as reported by the media for the first two months of 2013. Politicians worried Chelyabinsk meteorite fall February 15, 2013, and the flight of a larger celestial body below the orbits of communication satellites, which occurred on the same day.

"Two such important astronomical events that took place in one day, prove that we are living in an active part of the solar system — said Eddie Johnson, a Democratic congressman from Texas. — Dangerous objects fly past the planet with surprising frequency."

"We are fortunate that the events of the last few months were just an interesting coincidence, and not a disaster" — shared his opinion of the chairman of the Committee on Science Lamar Smith, a Republican from Texas. The Congressman added that the committee is interesting to know that NASA is doing to protect the United States and the planet from asteroid strikes, and how much money do I need to do it efficiently.

According to the adviser of the U.S. President for Science, John Holdren, who spoke to the Congress, to end our civilization may object diameter of 1 kilometer. He noted that the detected only 10% of the 10 million celestial objects with a diameter of more than 50 m, which could threaten the planet. According to statistics, asteroids of this size fall to Earth about once every one thousand years.

"We have no information about any because an asteroid threatening the population of the United States — the head of NASA, Charles Bolden. — But, if such an object will fall less than three weeks, pray." The Minister explained that there is now a technology that could have prevented the disaster if a threat is detected too late. At the same time, scientists are developing several methods of changing the trajectory of large objects. Each of these projects so far examined in the theory.

The interest of the threats from space has increased dramatically since the fall of the meteorite Chelyabinsk, which occurred on February 15. The shock wave smashed windows in three thousand buildings, more than a thousand local residents suffered from cuts and broken windows falling window frames. Scientists estimate that the released energy equivalent to the destruction of the meteorite explosion from 100 to 200 kilotons, the diameter of the heavenly bodies do not exceed 20 m, and its speed was about 30 km / second.
