Earth is NOT prepared for a deadly asteroid strike says White House science advisor

Earth is not prepared for the possibility of a cataclysmic asteroid collision, according to the White House's top science advisor. At a discussion on Wednesday at Nasa's Goddard Space Flight Center regarding the agency's 1.4 billion Asteroid Redirect Mission, director of the Office of Science and Technology Policy John Holdren warned that an impact could'do a lot of damage to the Earth.' The expert noted two catastrophic events in recent history that took the world by surprise – the Chelyabinsk strike in 2013, and the Tunguska fireball in 1908. While it may sound alarming, Holdren says we are'on a trajectory' toward mitigating the risks, as Nasa's radical mission has recently been given the green light to move forward, and could provide a platform for the testing of crucial deflection methods.
