Session Proposal: Latest Developments in Planetary Defense (AGU25)

NH029
Latest Developments in Planetary Defense

Session ID#: 250688

Session Description:
Planetary defense is the effort to detect and mitigate threats from objects like asteroids and comets, with the goal of preventing or minimizing potential impacts with Earth. This session will delve into the asteroid impact hazard and any recent developments in the field of planetary defense. Topics will include deflection simulations and experiments, characterization of asteroid physical and structural properties, surface morphology, the dynamics of small bodies, and the effects of impacts into Earth. By leveraging simulation models and characterization data, the session aims to inform mission design and optimize the effectiveness of mitigation approaches.  We welcome contributions from diverse research perspectives to foster interdisciplinary collaboration and advance global planetary defense efforts.
