The Engadget Interview NASA astrobiologist Dr David Morrison talks Asteroids and the end of the world

Between the recent meteorite strike and our close call with 2012 DA14, we've all been thinking an awful lot about potential impact hazards from the heavens. Thankfully, however, during our visit to NASA Ames last week, much of our fear was put to rest by astrobiologist Dr. David Morrison, the scientist who coined the word "cosmophobia" to describe the fear of external impacts on Earth. Morrison, who recently served as one of the go to sources for science fact (and common sense) in stories about the 2012 Mayan Apocalypse speculation, spoke to us about the likelihood of major asteroid impact on Earth -- and what we can do to stop it. Hang around after the break to check out our full interview with the good space doctor.
