On February 15, 2013 a meteorite weighing about 1 kilogram fell to Chelyabinsk. Such an event simply blew all the news lines and hurt the interests of many people. The European Space Agency (ESA) did not stand aside and appreciated all the information. This was the reason for the improvement of the space program “hunting for asteroids”.
On February 15, a large fireball was registered over Chelyabinsk, it flew from the northeast to the southwest at an angle of 20 degrees above the horizon at a speed of about 18 km / s (64,800 km / h, 40,000 mph). Thousands of people witnessed the incident. Also, the fall was recorded on car DVRs, this is what allowed the whole world to see this catastrophe. It is estimated that the base mass of the 17-meter meteorite is between 7,000 and 10,000 tons. It exploded at 3:20:26 GMT over 55 ° 10 N, 61 ° 25 ‘E at an altitude of 15 to 20 kilometers with a force of 500 kilotons.
Nikolai Bobrinsky gave an interview on the topic: "Who is responsible for the space situational awareness of objects approaching Earth." He spoke about some results and their significance in identifying similar meteors, and how they hit the Earth.

Approximately on the same day, the asteroid 2012 DA14 passed surprisingly close near the Earth, this may force some people to believe that the 2012 meteorite is a 2012 DA14. Despite the timing, the orbits of these two objects do not coincide, and therefore, the events on Friday were just a coincidence.
In Chelyabinsk, the meteorite damaged a lot, not only the surface of the earth, but also the windows, since they could not withstand the high pressure that caused the fall of the meteor.
They say that the meteor fragments scattered not only at a relatively small radius around the fall site, but were found in Lake Chebarkul along the trajectory of the meteor, but the Russian authorities still do not confirm this information.

The main task of ESA is a report study of 600,000 known asteroids in our Solar System and, in particular, 9000 that pass close to the Earth. The agency is working with NASA and the European National Space Agency to develop an early warning system for asteroids.
In 2008, 20 hours before the strike, the future of the fall of the Koschny meteorite was accidentally discovered in Sudan. If the meteorite in Chelyabinsk had also been warned, then people in the region would have enough time to leave the region.

As part of its program to provide such a warning, ESA is working on an extensive sky survey using six automated 1-meter (39.4-inch) telescopes for photographing the sky. By comparing images taken at different points and times, it would be possible to detect any new objects orbiting the Sun by their displacement in the images. From these shifts, the trajectory of the object can be calculated and threats to the Earth, if any, can be assessed. According to the ESA, such a survey would be able to detect a meteor that fell in Chelyabinsk even a few days before the impact.
