How Will Scientists Save The World From Ending
The biggest experiment has started. Imagine if a large asteroid or a very large rock starts growing in the direction of the whole earth and as soon as it hits the earth, there is a danger of the destruction of the entire human civilization. So what can be done to stop that
I When there is a war between two countries, different types of missiles are fired. To destroy these missiles, the world’s powerful countries deploy Missile Defense Systems. India has bought one such missile defense system from Russia, whose name is S-400. This system is capable of destroying enemy missiles in the air itself. But imagine for a moment if a large asteroid or a very large rock starts growing in the direction of the whole earth and as soon as it hits the earth, there is a danger of the destruction of the entire human civilization. So what can be done to stop that? The world will be saved from
DART! America’s space agency NASA has taken a big step towards averting this future threat. The mission that NASA has launched for this is named Double Asteroid Redirection Test. This DART is a 19 meter high spacecraft, which will lightly hit a 163 meter large meteorite named Dimorphos in the early months of 2022. This meteorite is 10 million kilometers away from Earth. Due to this collision,
Dimorphous will deviate slightly from its path. This collision will be very minor. But if a rock or meteorite moves towards the earth in future, then its path can also be changed with the help of this technology and the danger of it hitting the earth can be avoided. This meteorite revolves around another meteorite bigger than itself, which is named Didymos (Didimos). Its size is 780 meters. According to the principle of gravity, whichever body has more gravitational force in space, smaller bodies start rotating around it. Like the Moon revolves around the Earth and the Earth revolves around the Sun.
That’s why you can also call Dimorphous the moon or satellite of Didymos. by Taboola Sponsored Links You May Like For age above 30 years – 1 crore life insurance only ₹ 1413/month*.

Scientists selected 2 meteorites together for this great experiment because if DART collided with only one meteorite, then it would have deviated only 0.000006% from its path.
It would have taken many years to calculate this change. At the same time, due to this collision, if Dimorphos deviates from its orbit, then this change will be about one percent. Dimorphos orbits Didymos and during this time it also blocks the light coming from meteorites larger than it to some extent.. but when DART at a speed of 6.6 kilometers per second. If it collides with this meteorite and changes its path, then the light it stops will also change and scientists will be able to calculate it with the help of powerful telescopes in one to two months. The development of this technology is important because in our solar system, at present, more than 7 lakh meteorites of small and large size are continuously revolving around the Sun and the planets. And the number of known meteorites orbiting the Earth is more than 27 thousand. Most of these are small size. But there are also 2 thousand meteorites, which are considered dangerous and on which scientists keep an eye on them. Human civilization may end If a meteorite 150 meters in size also collides with the Earth, then this collision will release the energy of an atomic bomb, which can kill thousands of people.
If a meteorite 300 meters in size hits the earth, then an entire continent can be destroyed and if an even bigger meteorite or rock hits the earth, then the entire human civilization can also be destroyed and this has happened once. Is. It is said that about 60 and a half million years ago a meteorite 10 km wide collided with the Earth. Then the world used to be ruled by Dinosaurs, but within a few hours of this collision, their name was lost from the earth and at that time 76 percent of the species present on the earth became extinct forever. This incident may happen at any time in the future. But now scientists are trying to stop this apocalypse and NASA’s DART mission
