DART Mission and Asteroid Impacts

The video explores the Chicxulub Impact Event, a massive asteroid collision that occurred 66 million years ago, leading to the extinction of the dinosaurs. It discusses the global consequences of such impacts, including the disruption of the food chain. The video also addresses the potential threat of future asteroid impacts and NASA's efforts to monitor and deflect them, highlighting the success of the DART mission in altering the orbit of an asteroid.
