An examination of asteroids through the solar system, both in terms of dangers and benefits. Experts comment on what we do know of them, why they're hard to track, and what might be learned from them. The documentary also explores the possibility of asteroids as a fuel source for space travel, as well as the threat posed by large asteroids. The Tunguska strike is examined, as is the more recent incident in Siberia, which of course has a wealth of video evidence. Fascinating material, and well presented by PBS.
