Missiles may be used to shoot down meteorites
     2016-February-16  08:53    Shenzhen Daily

    RUSSIAN scientists want to upgrade their nuclear missiles in order to prevent meteorites threatening to hit earth by smashing them while they are still in space.

    While it may sound similar to the plot of sci-fi disaster films “Armageddon” and “Deep Impact,” Russian scientists are planning to tweak their intercontinental ballistic missiles, ICBMs, to target meteorites.

    Russian news agency TASS reports the missiles would have the power to destroy meteorites measuring from 20 meters and up to 50 meters in size.

    Senior rocket researcher Sabit Saitgaraye, from the Makeyev Rocket Design Bureau, said they plan to test their missiles on the asteroid 99942 Apophis, which he believes will pass “dangerously close” to Earth in 2036.

    Discovered in 2004, the asteroid, which is the size of three-and-a-half football fields, gathered the immediate attention of space scientists and the media when initial calculations of its orbit indicated a 2.7 percent possibility of an Earth impact, but the possibility was later ruled out.

    Saitgarayev said: ‘Most rockets work on boiling fuel. Their fueling begins 10 days before the launch and, therefore, they are unfit for destroying meteorites similar to the Chelyabinsk meteorite in diameter, which are detected several hours before coming close to the Earth.

    “For this purpose, intercontinental ballistic missiles can be used, which requires their upgrade.”  (SD-Agencies)
