At this moment there may be an asteroid or comet hurtling towards the Earth that could wipe out civilization and/or bring about global climate change. In this Café Scientifique, the director of the Asteroid Deflection Research Center at Iowa State University, Professor Bong Wie, describes the latest science, engineering and technology that could deflect asteroids and prevent the end of the world as we know it.

This presentation was recorded on Tuesday June 5th, 2012, at the Science Center of Iowa in Downtown Des Moines, in front of a general audience. The lecture series is sponsored by Pioneer Hi-Bred.
