A NASA Já Sabe Como Parar um Asteroide? | Sérgio Sacani

Can NASA really stop an asteroid from destroying Earth? In this video, Sérgio Sacani explains how Planetary Defense works, the set of technologies and strategies developed to detect, monitor, and even deflect potentially dangerous asteroids before they hit our planet. During the conversation, you will learn about historical cases such as the Chelyabinsk event in Russia in 2013, the mysterious Tunguska event in 1908, and the impact that led to the extinction of the dinosaurs about 66 million years ago. In addition, Sérgio Sacani details NASA's DART mission, humanity's first real test of altering an asteroid's orbit in space. Are we prepared for a future cosmic threat? How big is an asteroid capable of destroying an entire city? How does NASA monitor thousands of near-Earth objects every day? And what would happen if a large asteroid were actually on a collision course with our planet? FULL EPISODE: SÉRGIO SACANI (SPACE TODAY) AND ROBERTA DUARTE - Inteligência Ltda.
