NH14B:
Characterization of Asteroids, Risk Assessment, and Planetary Defense II


Session ID#: 10931

Session Description:
This session will focus on the characterization of near-Earth objects (NEOs), and the development of ways to assess and mitigate the risk they pose to life and infrastructure on Earth. Attributes to be characterized include material properties, shape, physical structure (including internal structure and surface morphology), small body dynamics, spin states, and Earth impact effects. Characterization data serve as input for impact simulations and planetary defense scenario development using high performance computer models that are used to inform mission designers of the suitability and effectiveness of various mitigation methods, including kinetic impactors and nuclear explosive devices. This session is intended to bring together a broad spectrum of related research efforts, and a diversity of opinion is encouraged.
