Did you know that it’s #AsteroidDay?! Watch this animation to see a simulated asteroid breaking up during atmospheric entry at about 45,000 miles per hour. You’ll notice that a high-pressure shock wave forms around the asteroid causing it to fracture and flatten like a pancake.
In support of our Planetary Defense Coordination Office, researchers are creating 3-D models and using one of our most powerful supercomputers to produce simulations of hypothetical asteroid impact scenarios. Their results help first responders and other agencies to identify and make better informed decisions for how best to defend against life-threatening asteroid events.
