impact hazard and discussed the status of current
efforts to search for possibly threatening Near Earth
Objects. Included were discussions of the completeness of the current catalog, recommendations of the NASA Science Definition Team on extending the search to smaller NEOs, and proposed deep surveys to look for sub-kilometer Near Earth Asteroids.

Threats and Consequences II

Chaired by:
David Morrison, NASA Astrobiology Institute
Don Yeomans, NASA Jet Propulsion Laboratory

Presenters in this session discussed the hazard to
humans posed by NEO impacts, radar reconnaissance of potentially hazardous asteroids and comets, concepts for obtaining long warning times on long-period comets and small asteroids, how the probability of impact of an approaching NEO object varies with time after detection, possible NEO impact scenarios, and the four planning scenarios developed by the conference steering committee.
