Could we actually stop an asteroid before it hit Earth, or are we just hoping nothing big ever shows up?

We get into the real state of planetary defense, from how NASA's DART mission tested asteroid deflection by slamming a spacecraft into a near-Earth object, to how scientists track thousands of these objects using ground and space telescopes. You'll learn what asteroid detection actually looks like today, why early warning time matters more than raw firepower, and where the gaps still exist in space technology built for planetary defense.

Whether Earth is actually ready depends entirely on which asteroid shows up first.
