In 2013, a house-sized asteroid exploded over Chelyabinsk, Russia, with the force of 30 atomic bombs. A century earlier, an asteroid impact flattened 830 square miles of Siberian forest. And while Hollywood loves to dramatize asteroid threats, the real work of planetary defense isn’t happening in action movies—it’s happening in research labs.

At Lawrence Livermore National Laboratory, a team of scientists is racing against time to track, deflect, and prepare for the next asteroid threat. They’re using cutting-edge simulations, kinetic impact tests, and global collaborations to ensure Earth is ready before disaster strikes. In this episode, we uncover how planetary defense has evolved from theory to reality—why asteroid threats are more real than most people think—and what it will take to stop a civilization-ending impact.

Because the next asteroid isn’t a question of if—but when.
