For more than 20 years, NASA and its international partners have been scanning the skies for NEOs, which are asteroids and comets that orbit the Sun and come within 30 million miles (50 million kilometers) of Earth's orbit. International groups, such as NASA's Planetary Defense Coordination Office (PDCO), the European Space Agency's Space Situational Awareness-NEO Segment and the International Asteroid Warning Network (IAWN) have made better communication of the hazards posed by NEOs a top priority.
In the spirit of better communication, next week at the 2019 Planetary Defense Conference, NASA's PDCO and other U.S. agencies and space science institutions, along with international partners, will participate in a "tabletop exercise" that will play out a realistic -- but fictional -- scenario for an asteroid on an impact trajectory with Earth.
Exercise - Emergency - Disaster - Management - Planning
A tabletop exercise of a simulated emergency commonly used in disaster management planning to help inform involved players of important aspects of a possible disaster and identify issues for accomplishing a successful response. In next week's exercise, attendees at the conference will play out a fictional NEO impact scenario developed by the NASA Jet Propulsion Laboratory's Center for NEO Studies (CNEOS).
"These exercises have really helped us in the planetary defense community to understand what our colleagues on the disaster management side need to know," said Lindley Johnson, NASA's Planetary Defense Officer. "This exercise will help us develop more effective communications with each other and with our governments."
Type - Exercise - Part - National - Near-Earth
This type of exercise is also specifically identified as part of the National Near-Earth Object Preparedness Strategy and Action Plan developed over a two-year period and published by the White House in June 2018.
These exercises are not tightly scripted. The point is to investigate how NEO observers, space agency officials, emergency managers, decision makers and citizens might respond to an actual impact prediction and evolving information....
