"These events are not of the & # 39 are a rarity": NASA exercise highlights the existential threat of an asteroid impacting Earth

This doomsday scenario for a Hollywood blockbuster – and NASA scientists are going to see it go down.

This week, researchers will work on the exercise of planetary protection conference in 2019, which will play for the "realistic scenario" asteroid, flying space on the trajectory of impact with the Earth, according to NEWS.com.au

NASA's Planetary Protection Coordination Center (PDCO) running simulation exercise in the framework of the recently announced federal "action plan" to protect our planet from the asteroid impact.

Hypothetical asteroid, believed to be around 100 to 300 meters in size and only has a very small probability crashed into the Earth April 29, 2027, according to NASA's Web page dedicated to a very detailed script.

Global astronomers are always in search of the Earth & # 39 objects (NEOs), which are classified as asteroids and comets that orbit the Sun, and came to 50 million kilometers of the Earth's orbit.

Together with NASA unit, Space Situational awareness-NEO segment of the European Space Agency and the International Asteroid warning network (IAWN) tasked to hunt in the sky of potentially dangerous space rocks.

These "post exercise" is not of & # 39 are rare and about walking through the steps that will be taken together with governments and emergency response agencies in order to reduce the risk to society unthinkable should happen.

"These exercises have really helped us in the planetary protection of society, to understand that our colleagues on the side of the emergency management should know," said Lindley Johnson, NASA's planetary protection officer. "This exercise will help us to develop better communication with each other and with our governments."

NASA has been tasked to identify and track 90 percent of near-Earth meteors that are more than 140 meters up to 2020, but the task can end up taking nearly three decades, experts say. And even if we are far from protected.

Last month it was revealed a relatively small and unnoticed meteor exploded over the Bering Sea, off Kamchatka in the December 18 blast – which occurred 25.6 km above the Earth's surface – released 10 times the energy generated by the atomic bomb dropped on Hiroshima during World War II.

Six years ago, a meteorite exploded over the Russian city of Chelyabinsk and produced a shock wave that shattered thousands of windows and injured more than 1,600 people. This meteorite was a width of 19 meters.

"It is one of the Chelyabinsk and the last one (in December) is about 10 times less," that those covered by the mandate of NASA, astronomer Alan Duffy explained News.com.au last month. "It is much harder to detect those, and we still have not found all the major asteroids yet."

He called for more funds to be allocated for monitoring systems, claiming "it's just a matter of time before one of these explosions going on over the city and cause incredible damage."

During his opening speech at the opening of the planetary defense conference, NASA administrator Jim Bridenstina warned to prepare for asteroid & # 39 is that it must be very serious & # 39; ozna.

"We need to make sure that people understand that this is not Hollywood, this is not about the movie. This is about the long run, protecting the only planet we know, right now, to spend my life, and that the planet Earth, "he said.
"These events are not uncommon, they do occur."
