China's asteroid-destroying diversion plan



Souce


In recent years, several options have been proposed to avoid a disaster that sooner or later is going to occur, it is only a matter of time that some of these objects in the cosmos, of which we already know almost 1,100,000, end up on a collision route with the earth.


A few weeks ago, Chinese researchers published a radical proposal that would launch Long March 5 rockets against the potentially dangerous asteroid, which are the highest capacity China has, each weighing about 900 tons, these rockets would be equipped with deflectors at the front. , in order to avoid the fragments that detach from the asteroid during impacts in order to divert the asteroid from its path.

The idea is similar to the one published by NASA in 2018 that calculated that an asteroid could be deflected by launching Delta 4 rockets that are 733 tons, the Chinese made their calculations taking as an example the asteroid Bennu, which is about 490 meters high. diameter and that in case of impact with the earth it would be able to completely destroy a large city, for an asteroid the size of a penis if we had a margin of 10 years to react it would take 75 rockets of the NASA Delta 4 type, while It would only take 23 Chinese long march rockets, since they are bigger.

It is true that there are many launches and many rockets, but if we knew the trajectory of the asteroid precisely and had a margin greater than 10 years, the number of rockets needed could be reduced, although at present there is no asteroid the size of Bennu or greater in peace. collision route with the earth, not at least in the next 100 years, in the longer term there are some asteroids, among them Bennu with a very very low risk of collision.

And it is true that there is a risk that a new asteroid of less than 150 meters will appear, that even if it is smaller than Bennu it can also cause great destruction and that this asteroid ends up giving us a scare with hardly any margin of reaction, of that size or perhaps even less there is much debate on the subject, it must have been the asteroid that caused the 1908 event in Tunguska in Siberia destroying 2,152 square kilometers of forest, but luckily the asteroids are not infinite there are many, yes but they are a number limited and thanks to the work of astronomers every day more are known, thus reducing the number of unknown asteroids and therefore those that can cause us an unpleasant surprise.
