Decipher the mystery of the meteorite

Many large and small devastations by meteorites have occurred throughout the history of tens of billion years of Earth existence. Many countermeasures have also been studied. But, until now, that threat still exists and people are still waiting for the luck of fate .

'Uninvited guests'

After more than a hundred years of meteorites, they became 'uninvited guests' to visit Russia.

The first uninvited guest 'visited' this country in 1908, exactly about 7am on June 30, 1908, in the Tunguska region, in Siberia, northeastern Russia, as an asteroid, an asteroid array big size It flew across Earth at a close distance, 5 - 6km and exploded.

The power of the explosion blew away a large area of ​​forest within a radius of 20.9 km, devastating all houses, people and livestock within 2,000 square kilometers.

The second 'guest' arrived just after Valentine's Day this year, also in the morning, around 9:30 am on February 15, 2013.

According to the announcement of the local emergency agency, meteorite with a diameter of 15 meters, a weight of about 7,000 tons rushed into the atmosphere at a speed of 64,000km / h and exploded at a height of 19-24km above the ground , causing meteorite rain in the sky of the provinces of Chelyabin, Tyumen, Kyrgan, Sverdlovsk and many localities along the Urals mountains.

The explosion of meteorites emitted a bright light in the sky, creating a large shockwave, breaking many glass doors and seriously damaging houses, schools, hospitals, zinc factories, stadiums. ice Hockey…

In Chelyabin province alone, there are 100,000 houses, hospitals and schools with broken glass or broken roofs with an estimated total loss of over 1 billion rubles (over 33 million USD). According to the report, the meteorite explosion occurred more than 300-500 kilotonly, equivalent to 20 US atomic bombs dropped on Hiroshima, Japan in 1945.

According to RIA Novosti news agency, there are more than 1,200 people in the local area injured, of which two-thirds of people are due to broken glass pieces or other materials blown from a meteorite explosion and 50 people must hospitalize. But, "Thank God, nothing falls into the living area" (President Vladimir Putin's words).

The meteorite fell into a lake just outside the town of Chebarkul in Chelyabinsk province, creating a 6-meter-wide crater on the ice covering the lake.

Russian scientists said that in the 19th and 20th centuries, in the world and in Russia there were hundreds of meteorite rain, but often occurred at night and did not cause great loss of life and property.

Astronomers commented that, in the 19th and 20th centuries, in the world and in Russia there were hundreds of meteorite rain, but often occurred at night and did not cause great damage to humans and property. this time. The way to inflict human casualties is also new and seems to have no such precedent before.

Another feature, the aforementioned meteorite event occurred in the modern era, so the recording media, video recording and video were promptly saved in abundance of what happened in the sky and under the ground in many different angles. The information obtained will be analyzed, researched and given very useful scientific data in the future.

New 'guest' - meteorite 2012 DA 14?

According to published calculations of space research agencies of countries, meteorite 2912 DA14 will fly across the Earth on February 15, 2013, so many question whether this meteorite is ' a guest ' Uninvited by Russia this time.

However, according to the European Space Agency based in Darmstad City, Germany, the meteorite explosion that happened in central Russia has absolutely nothing to do with the 2012 meteorite DA14.

First of all, the orbit of the meteorite 2012 DA14 until the evening of February 15, 2013 in the US time (ie morning of February 16, Vietnam time) is still no less than 27,700km from the earth at a speed of 28,000 km / h. . In that distance, although it is closer to earth than satellites in geostationary orbits, it is still very far from Earth and cannot cause any devastation like the incident on the morning of Thursday 15 February. 2013 past.

In particular, as Dr. Robert Massey of the Royal Astronomical Society said, "The meteorite rain in Russia moves from East to West, while the DA14 meteorite moves from North to South." It is a valid and scientific evidence to affirm that DA14 2012 meteorite is not the culprit of the "terrorist" incident in Russia for the second time on February 15. Astronomers think this is just a coincidence. Reportedly, 2012 meteorite information DA14 was discovered last year and is still being closely monitored.

Another question to ask is, a meteorite rain falling to Earth left a rather big corollary as happened on February 15, 2013 why did astronomical agencies not predict it? We hope astronomers will give answers as soon as possible.
