Huge asteroid that ‘could wipe out human life’

Huge asteroid that ‘could wipe out human life’ heading for Earth, scientists say

LONDON: Scientists have moved closer to being able to stop a huge asteroid colliding with Earth and potentially wiping out human life. Researchers at the University of Tennessee have discovered that blowing the space rock up could make the collision worse by causing several devastating impacts.

Instead, small changes could be made to its surface to disrupt the forces keeping it together and cause it to break up in outer space.

They were studying Asteroid 1950 DA, which has a one in 300 chance of hitting the planet on March 16, 2880.

Although the odds seem small, it is the most likely asteroid to collide with Earth and the odds are higher than being shot dead in the US.

The fastest cruise missile in the world

Brahmos: The fastest cruise missile in the world

This is the first underwater launch of the BrahMos, the world's fastest cruise missile in operation capable of flying at Mach 3.0. I just like to see it pausing and changing direction in mid-air, like a scene from Robotech.

The Indo-Russian supersonic aircraft carrier killer was tested from an underwater pontoon on the Bay of Bengal on March 20, 2013, but it can be launched from any platform imaginable: Military ships, trucks, aircraft, and submarines. They are now working on a Mach 7 hypersonic BrahMos-II. Tests will start in 2017.
