The asteroid belt is portrayed in movies as a crowded place with massive rocks bouncing each other like pool balls, capable of sending a mile-wide missile hurtling toward Earth at any moment. The reality is much more fascinating.

Host Dr. Michelle Thaller speaks with Dr. Lucy McFadden, Co-Investigator of NASA’s Dawn Mission to orbit the asteroids Vesta and Ceres. She shares what they’ve learned by traveling 130 million miles to visit places we’ve always viewed from afar.
