Speaker: Dr. Megan Syal, Lawrence Livermore National Laboratory
Topics covered in this webinar:
- The question of how to defend Earth from hazardous asteroids and comets.
- The National NearEarth Object Preparedness Strategy and Action Plan, released by the White House’s Office of Science and Technology Policy in 2018.
- Improving simulations of asteroid mitigation.
- Effective methods for asteroid impact avoidance, kinetic impact deflection and nuclear deflection or disruption.
- Strengthening impact emergency procedures using accurate shock physics simulations.
- New meshless methods for assessing airburst consequences.
- Large ocean-wave generation, propagation, and flooding from asteroid impacts
- Simulations to support the first asteroid deflection test, to be carried out by NASA’s DART mission at the “moonlet” asteroid Dimorphos in 2022.
- Recent work to improve multiphysics modeling and simulation capabilities for nuclear and kinetic deflection of asteroids.
