NASA’s Plan to Stop an Asteroid Headed for Earth

Like this video about how NASA is preparing to stop an asteroid headed for earth, and subscribe. Estimates say that a vehicle-sized asteroid explodes in our atmosphere about once per year, often too high to make a noticeable impact. But in 2013, a small meteor exploded just 20 miles above Chelyabinsk, Russia that sent over 1,200 people to the hospital. Today, a team of experts from NASA’s Planetary Defense Coordination Office works diligently to find asteroids that travel near Earth’s orbit.They’ve released a plan in order to prevent a large-scale asteroid impact, and part of this plan is the DART mission. DART aims to travel to the asteroid Didymos in 2021 to demonstrate the tech that could be used to redirect an asteroid headed for Earth.
