What Is NASA's DART Mission and Its Impact on Asteroids?

TL;DR

NASA's DART mission seeks to test a technique for deflecting asteroids by colliding with Dimorphos, a small asteroid. This is the first planetary defense test of its kind, crucial for protecting Earth from potential asteroid threats. The spacecraft, equipped with an autonomous navigation system, is on track to successfully alter the asteroid's orbit.
