How do active asteroid missions protect Earth from potential impacts?

Active asteroid missions are like having a superhero team that watches out for space rocks and keeps Earth safe from big crashes.

Imagine you're playing catch with a friend, but instead of a ball, it's a giant rock flying through the sky. If it misses your hand, it might hit Earth, ouch! That’s what happens when an asteroid hits our planet. But active missions help us know where these rocks are going and maybe even stop them.

Asteroid missions send special space probes to visit or even touch asteroids. These probes are like smart detectives who take pictures, measure the size, and sometimes even give a little push to the asteroid. That helps scientists figure out if it's heading our way.

If we know an asteroid is coming, we can plan how to stop it, maybe by sending another probe to bump it off course or use a special trick to make it break apart. It’s like moving a big rock out of the path before it hits your toy house!

By watching and working with these space rocks, we’re making sure Earth stays safe from surprise visits.
