The International Academy of Astronautics will hold its 6th conference  from April 29 to May 3rd, 2019 in the USA. The bi-annual conference brings together world experts to discuss the threat to Earth posed by asteroids and comets and actions that might be taken to deflect a threatening object.

  • Key International and Political Developments
  • Advancements in NEO Discovery
  • New NEO Characterization Results
  • Deflection & Disruption Modeling and Testing
  • Mission & Campaign Design
  • Impact Consequences
  • Disaster Response
  • Impact Risk Assessment and Decision to Act
  • Public Education and Communication

The conference will include a hypothetical NEO/Earth impact event scenario that will be part of the conference (similar to what was done at the 2013, 2015 & 2017 conferences). Conference attendees may also use the hypothetical scenario as their topic for papers and presentations.

Although this scenario is realistic in many ways, it is completely fictional and does NOT describe an actual potential asteroid impact.
