Researchers want to ‘slice and dice’ deadly asteroids with rocket-powered bombs, new paper says

A group of researchers wants to save Earth from a potential asteroid apocalypse using a new planetary defense method they call PI — short for “Pulverize It.”

The plan — detailed in a lengthy technical paper on the University of California, Santa Barbara (UCSB) Experimental Cosmology Group website and submitted to the journal Advances in Space Research — aims to smash large, potentially life-threatening asteroids into hundreds of tiny pieces by launching an array of “penetrator rods” into the asteroid’s path.
