NH13A:
Asteroids: Surveys, Characterization, Impact Risk, and Mitigation II Posters

Submit an Abstract to this Session



Session ID#: 24316

Session Description:
This session will address near-Earth asteroids and the development of ways to assess and mitigate the risk they pose to human life, infrastructure, ecosystems, and the global environment. Risk assessment and mitigation includes characterization of material properties, shape, physical attributes (including internal structure and surface morphology), small body dynamics, spin states, and Earth impact effects. Characterization data are required for impact simulations and planetary defense scenario development using high-performance computer simulations. These models inform mission designers of the suitability and effectiveness of various mitigation methods, including kinetic impactors and nuclear explosive devices. This session will also address asteroid research for other purposes including science, human exploration, and resource development.
