The Earth is constantly bombarded by asteroids, from a steady drizzle of dust to occasional extinction-level events. Uniquely among natural disasters, the human race has developed the capability to prevent at least some of these impacts. Andy Rivkin will discuss what we know about asteroids and their natures, as well as the different techniques being considered for deflecting or destroying any dangerous objects, were they to be discovered. The class ends with a discussion of the DART (Double Asteroid Redirection Test) spacecraft concept, designed to demonstrate and test our capabilities in planetary defense.
