Catastrophic asteroid strike: how prepared are we?


Many asteroids crashed on Earth with huge impacts. Furthermore, the rock that wiped out many dinosaur species about 65 million years ago. A global nuclear weapons monitoring agency has detected 26 asteroid explosions with more power than a nuclear bomb in the 13 years between 2000 and 2013, according to a report.

There are more than seven lakhs asteroids in space that are found by astronomers. It should be noted that asteroids are found mainly in an area called the "main belt", between the orbits of Mars and Jupiter. Recently, we have seen many asteroids including 2019 NN3, 2019 MB4, 2019 MT2, 2006 QV89, 2016 NO56M, RF12 and others crossing our planet. However, not everyone has hit the Earth and we have been lucky enough. You could agree with the fact that the asteroid, if it hits the Earth, can cause massive destruction on the planet. Have you ever heard of asteroids called 99942 Apophis?

The Apophis of 99942, extends for about 340 meters (340 meters) and will pass harmless from the Earth, about 31,000 km above the surface, on 13 April 2029.

"The close approach of Apophis in 2029 will be an incredible opportunity for science," said Marina Brozovic, radar scientist at NASA's Jet Propulsion Laboratory in Pasadena, California, who works on radar observations. of objects close to the Earth (NEO).

"We will observe the asteroid with both optical and radar telescopes, with radar observations we could see details of the surface of a few meters," said Marina Brozovic.

Catastrophic asteroid strike: how prepared are we?

In 2016, a NASA scientist warned that the Earth is not prepared for such an event. In April 2018, the B612 Foundation reported "It is 100% certain that we will be affected (by a devastating asteroid), but we are not 100% sure when". Also in 2018, physicist Stephen Hawking, in his latest book Brief Answers to the Big Questions, considered an asteroid collision to be the greatest threat to the planet.

Avoidance of asteroid impacts includes a number of methods by which objects close to the Earth (NEO) could be deflected, avoiding destructive impact events. A sufficiently large impact from an asteroid or other NEOs would cause massive tsunamis, multiple storms and a winter of impact caused by the blocking effect of large quantities of large quantities depending on its location of impact. powdered rock dust and other debris, in the stratosphere.

According to the testimony of United States Congress experts in 2013, NASA would have required at least five years of preparation before a mission to intercept an asteroid could be launched.
