S1E3 Killer Asteroids

Earth is always at risk from asteroids, with countless ones drifting perilously close to our planet. In Arizona, we meet a dedicated team that spends their nights monitoring the skies for these potential threats. They also demonstrate an experimental laser beam designed to redirect an asteroid away from Earth. But could these menacing space rocks hold more than just doom? At NASA, astronauts undergo training in zero gravity for a pioneering manned mission to an asteroid, while we explore the possibility of asteroids serving as cosmic refueling stations.
