Detecting and Deflecting Asteroids on a Collision Course with Earth

World famous former Astronauts Rusty Schweickart and Ed Lu talk about how and why we should be doing more to Detect and Deflect Asteroids on a Collision Course with Earth at the MIT Enterprise Forum in Houston. The technology exists today to defend the Earth from city killing and planet killing asteroids but unfortunately very little is being done today and more should be done. Rusty and Ed also discuss the geopolitical challenges of deflecting asteroids.
