The two US authorities are working with international groups such as the NASA Planetary together the Defense Coordination Office (PDCO), the Space Agency's Space Sensitivity Segment (NEO) and the International Asteroid Warning Network (IAWN).
The NASA Jet Propulsion Laboratory (NEO) Center for NEO Studies developed the fictitious premise.
This is the picture they painted: It's March 26, a NEO that's potentially dangerous to Earth. After tracking an asteroid they had been calling PDC for 2019 for months, they found that by 2027, they would have a 1 in 100 chance for Earth. (Scientists have identified these opportunities as action thresholds.) What will emergency management officials and scientists become
"These exercises really helped us in the planetary defense community understand what our colleagues in disaster management need to know," said NASA's planetary defense officer , Lindley Johnson, in a statement. "This exercise will help us develop more effective communication with each other and with our governments."
Practice Makes Perfect
NASA has participated in six similar NEO impact exercises so far. And as NASA searches for more precise potential influences and effects as well as orbital motion patterns, they will be able to make more accurate predictions in the event of a real threat.
