Asteroids have reshaped Earth before—and scientists know another impact is inevitable. When traditional deflection methods won’t work, what’s the last resort?

At Lawrence Livermore National Laboratory, experts are exploring nuclear deflection: using nuclear energy to alter an asteroid’s path or break it apart before impact. But how does it work, what are the risks, and how prepared are we to use it when the time comes?

This is the second episode in our Planetary Defense series.
