NASA simulates asteroid impacts to help identify possible life-threatening events

29 Jun 2017 Ames - When an asteroid struck the Russian city of Chelyabinsk in 2013, the blast from the asteroid's shock wave broke windows and damaged buildings as far away as 58 miles (93 kilometers), injuring more than 1,200 people.

In support of NASA's Planetary Defense Coordination Office, researchers are creating 3D models and using one of NASA's 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.

High-fidelity simulations of potential asteroids covering a wide range of sizes were run on the Pleiades supercomputer using NASA's Cart3D and Lawrence Livermore National Lab's ALE3D modelling software by experts on the Asteroid Threat Assessment Project at the NASA Advanced Supercomputing facility at Ames Research Center in California's Silicon Valley.

The NASA team was able to run large-scale simulations of the Chelyabinsk asteroid event on Pleiades to produce many impact scenarios quickly, because Cart3D is dozens of times faster than typical 3D numerical modelling used for aerodynamic analysis. The detailed simulations allowed the team to model the fluid flow that occurs when asteroids melt and vaporize as they break up in the atmosphere.

NASA's asteroid research is shared with scientists at universities, national labs, and government agencies who develop assessment and response plans to look at damage to infrastructure, warning times, evacuations, and other options for protecting lives and property.

For more information on NASA's Asteroid Threat Assessment Project work, you can visit the NASA Advanced Supercomputing Division website.

The animation from an ALE3D simulation shows a Chelyabinsk-like asteroid breaking up during atmospheric entry at about 45,000 miles per hour, with a high-pressure shock wave that forms around the asteroid causing it to fracture and flatten like a pancake. Credits: NASA Ames/Darrel Robertson.
