Decoder Ring: A Feel-Good Story About the End of the World

The fear that the Earth could be destroyed by a killer asteroid is an anxiety that pops up all the time in fiction and is grounded in fact. But funnily enough—actually being pancaked by a giant space rock? Not something you need to spend a whole lot of time worrying about! And that’s because a bunch of NASA scientists and engineers are already worried about it for us. In this episode, science journalist Dr. Robin George Andrews tells us the story of NASA’s first-ever mission to defend the planet, which is the subject of his new book, How to Kill an Asteroid. This episode was written and produced by Sofie Kodner. It was edited by Willa Paskin and Evan Chung. Decoder Ring is produced by Willa Paskin, Evan Chung, Max Freedman and Katie Shepherd, with help from Sofie Kodner. Derek John is Executive Producer. Merritt Jacob is Senior Technical Director.
