The conference as currently planned is organized into the following sessions. Suggested topics are listed, but should not be viewed as being exclusive.

SESSION 1: DISCOVERY, TRACKING, CHARACTERIZATION
• Status of the discovery program
• Options for enhancing detection and tracking of near Earth objects
• Latest information on physical characteristics of asteroids (including Apophis) and
   comets
• Recent Earth and Mars close approaches
• Characterization of the types of threats faced: approach trajectories, impact
   probabilities, object sizes, likely warning times
• Radar tracking and physical characterization of NEAs
• Cratering on Earth and Mars as it relates to consequences of impact

SESSION 2: MISSION & CAMPAIGN DESIGN
• Information required to increase the likelihood of success for mitigation or close
   approach missions
• Deflection campaign designs that increase the probability of overall mission success
• Intercept orbits and mission time requirements
• Design of missions to characterize, track, or deflect threatening NEOs
• Engineering considerations for developing and operating a deflector spacecraft (e.g.,
   rapid spacecraft development, integration, testing; autonomy; communications;
   guidance and control)

SESSION 3: DEFLECTION TECHNOLOGIES & SIMULATIONS
• Technologies that might be used against a short term (2 month to 10 year warning),
   medium term (10-20 year warning), long term (>20 years warning) threats
• Effectiveness vs. object size, shape, properties
• Interceptor/diverter technology requirements and current status (propulsion, guidance,
   etc.)

SESSIONS 4: NEO IMPACTS & CONSEQUENCES
• Estimates of costs of impacts: financial, social, casualties, etc.
• Current information on past NEO impacts (e.g., Tunguska)

SESSION 5: POLICY, PREPAREDNESS, DECIDING TO ACT
• Factors that will influence the decision to take or not take action to mitigate a threat
• Evolution of a threat (detection, decision to act, action)
• Disaster preparation and response; lessons from recent disasters
• Public notice, public perception, education
• Suggested thresholds for deflection actions

SESSION 6: SUPPORTING ACTIVITIES
• Status of current UN and government-level policy discussions
• Specific ongoing and funded activities that support planetary defense
