Asteroids, which hit our planet at least twice each year, are the only natural disaster for which we have a technological solution. We are all living with the threat of a 3-minute experience that could transform our lives and our planet forever. Scientists have found 10,000 Near-Earth Objects, yet there are an estimated one million in our inner solar system, and the vast majority of the threatening ones are still undiscovered. In this non-technical talk, Ed Lu describe the threat, and discusses the Sentinel Mission, an orbiting telescope to detect and track asteroids that cross Earth’s orbit.
