P53D:
Mitigation and Consequences of Asteroid Impacts II Posters


Submit an Abstract to this Session


Session ID#: 63315

Session Description:
Planetary defense against asteroid impacts is an active field of research, which involves ground-based observations of small bodies, numerical modeling of deflection techniques, laboratory experiments, and space mission projects and technology developments. The asteroid impact hazard is the only natural hazard that can be predicted and prevented with feasible means, and it is inherently an international issue. NASA has undertaken the first demonstration and test of asteroid deflection using a kinetic impactor, and ESA is studying an orbiter spacecraft. This work has triggered important planetary defense activities: (i) definition and coordination of technology needs and requirements for planetary defense, (ii) modelling and simulations of impact outcomes including benchmarking of available simulation tools, (iii) remote sensing observations, instrument payload developments for in situ characterization, and definition of close-proximity operations. This session will discuss the various elements and their current state.
