Chinese researchers propose deflecting 'Armageddon' asteroids with rockets

When it arrives a year later, the NASA spacecraft will crash-land on the smaller of the two rocky bodies to see how much the asteroid's trajectory changes. It will be humanity's first try at changing the course of a celestial body.

At China's National Space Science Center, researchers found in simulations that 23 Long March 5 rockets hitting simultaneously could deflect a large asteroid from its original path by a distance 1.4 times the Earth's radius.
