NASA simulates the consequences of an asteroid that fell to Earth

Space agencies around the world will simulate emergencies when the planet is threatened by asteroids.

This will be discussed at the 7th Planetary Defense Conference.

Members of the NASA Planetary Coordination OfficeDefense Force (PDCO) will join other scientists and astronauts to simulate how agencies, governments and citizens should respond if Earth is threatened by an asteroid. For five days, they will simulate collision scenarios and must adapt their reactions to new incoming data.

“Every time we participate in the teachings of thissort of, we're learning more about who the key players in a catastrophic event are, and who needs to know what information should be sent to them and when, ”said Lindley Johnson, NASA's planetary defense officer. "These exercises ultimately help the community share information with other governments and ensure coordination in the event of a potential threat."

Scientists noted that they are now working with alla more sophisticated system of telescopes that can detect asteroids or comets approaching Earth; they are called Potentially Hazardous Objects (PHO). However, the researchers want to work out in more detail the scenarios in which such an object approaches the planet and can threaten its existence. In this case, space agencies should work out a plan for exercises and potential actions.

"Research on a hypothetical collision withasteroids give us an opportunity to think about how we will react if a significant asteroid is discovered that has a chance of colliding with our planet, - said Paul Chodas, director of the Center for the Study of Objects in Near Earth Space (CNEOS) at NASA's Jet Propulsion Laboratory. "The details of the scenario — such as the likelihood of an asteroid collision, where and when the collision might occur — are provided to attendees over several stages of the conference to simulate how the actual situation might develop."
