SAO Scientists have created a unique camera for monitoring


Scientists of the Special Astrophysical Observatory of the Russian Academy of Sciences (SAO) have created an automated system wide angle view of the sky, which allows to detect cosmic bodies, including the meteorites that threaten the Earth.

"The device is a camera with a large field of view of the sky and the high register. That is, in the event of any object in the sky, regardless of its speed and size, the device will be able to instantly detect it, calculate the flight path, a possible threat to the Earth and, in case of a fall to Earth, the exact crash site. When a threat is detected the system will give an alarm, "- said the director of SAO RAS corresponding member Yuri Balega.

According to him, the system is able to detect virtually any object at a distance of several tens of thousands of kilometers.

Balega said that the meteorite that fell near Chelyabinsk, such a device would be able to detect at a distance of 50-100 thousand kilometers from Earth, about 20-30 minutes before his fall. And if the car would be a threat to the locality, we would be able to warn the public about the threat and may even be evacuated.

However, the scientist said, this device is able to detect cosmic bodies only at night, because during the day because of the scattered light can not see anything.

Balega said that today in Russia there is a similar detection system, but they offer much lower because they do not have such a wide field of view and opportunities for extremely fast processing of information received.

"In general, to ensure full monitoring and control of the celestial bodies that may threaten Russia in the territory of our country enough to install about 10 of these systems by combining them into a single network. That would be enough for the rapid detection of possible threats, "- said the director of SAO.

The cost of a system of detection of cosmic bodies that threaten the Earth is about 20 million.

On March 12, in the Federation Council held a special meeting of the group on the asteroid threat, which might be considered is funding programs to protect against such "visitors" from outer space. It is possible that under this program in Russia will establish a network of sky survey and detection of cosmic threats.

The development of the instrument involved a group of scientists led by SAO scientist Gregory Beskina in collaboration with other scientists.


Falling debris. Over the Urals 15.02.2013 at 9:20 am local time (7.20 GMT, G+ 4) meteorite exploded.

Help "MIC"

Place: Chelyabinsk

Dimensions: initially two to three meters in diameter, and then split apart. As it turned out, in the process of studying images taken by the European meteorological satellite «Meteosat-10", the meteorite weighed about 7,000 tons and has a diameter of around 15 meters
