The solar system is a dangerous place, with asteroids barreling between the planets and frequently skimming past Earth. Just one 50-foot rock, like the one that exploded over Chelyabinsk, Russia in 2013, could kill up to a million people! Dr. Ed Lu, former NASA astronaut, co-founder of the B612 Foundation, and head of the Asteroid Institute joins us to talk about finding the millions of potentially dangerous asteroids that are still uncharted and how we might avoid catastrophic encounters.

Hosts: Rod Pyle and Tariq Malik

Guest: Dr. Ed Lu
