Asteroid Monitoring and Impact Assessment

The video discusses asteroid DA14, which is approaching Earth closely but will not collide. It highlights the potential catastrophic impact if such an asteroid were to hit a populated area. The video explains strategies to alter an asteroid's trajectory using probes and emphasizes the need for space-based assets to detect and monitor asteroids effectively.
