russian scientists zap tiny asteroids with lasers to protect earth from deadly strike  -  laser measurement system
An asteroid measuring less than an inch wide was blown up by a laser in labto to calculate how to prevent the Earth from being destroyed by huge space rocks.
Rosatom, Russia's national nuclear energy company, and a group of researchers from the Moscow Institute of Physical Technology (MIPT)
According to the composition of the stone meteorite that landed on Lake Chebarkul after the impact of the car yabinsk in 2013, a miniature asteroid was built.
They found that in order to eliminate an Asteroid 650 feet wide, the explosion would need to provide energy equivalent to three megabytes of TNT-
Equivalent to 200 Hiroshima bombs.
The most powerful explosive device was the "King of bombs" made by the Soviet Union in 1961, with an energy output of about 50 megabytes of TNT.
"At the moment, there is no asteroid threat, so our team has time to refine the technology to be used later in preventing planetary disasters," the research company said . "
Author Vladimir Yufa is an associate professor in the Department of Applied Physics, laser systems and structural materials.
"We are also looking at the possibility of deflecting an asteroid without destroying it and would like the international community to be involved.
"Asteroids are celestial bodies made of carbon, silicon, metal, and sometimes ice, which can be as large as 550 miles.
The space rock moves at a speed of 10 miles per second, posing a threat to destroy all life on Earth, similar to the destruction of the extinct dinosaurs 65 million years ago.
Nasa had previously said that the Earth should have suffered a huge asteroid impact. With the movement of the solar system, there are plans to map rocks around the world.
Professor Stephen Hawking Haas also said it was only a matter of time before the Earth was destroyed by rocks.
Last year, within 100 miles of Antarctica, a 27,000-foot steroid called 202c4 disappeared, a distance described by astronomers as "very close ".
If a huge rock eventually collides with the Earth, the only option is to try to transfer it or blow it up.
In some experiments, the laser targeted a cavity made on a miniature asteroid in advance and found that the nuclear bomb was more powerful than the bomb on the surface.
The team now plans to expand the study by experimenting with asteroid replicas of different components, including asteroid replicas containing iron, nickel and ice.
They also intend to determine more accurately the shape of the asteroid and whether there is a cavity on its surface that affects the general destruction criteria.
Details of the experiment are published in the Journal of Experimental and Theoretical Physics.
