Like every machine, the journey of satellites also comes to an end at some point, but have you ever thought about where they go after their life period is over, as they can't stay in space forever, and their sudden fall to earth can also cause terrible devastation. Then where and how would the satellite which is going to expire, finally be kept. Many countries have sent their satellites into space, and with each satellite, it is certain that it will expire after a fixed period of time. After its expiration, another satellite takes its place, but it is important to know what happens to the satellite that has expired.
There are two options for this and the choice among them is determined by how far the satellite is from the earth. So first, if the satellite is in a very high orbit, it may cost a lot of fuel to bring it back to Earth after a technical fault. In such a situation, scientists send it further into space so that it cannot return to Earth's orbit. Another option that has been useful for most satellites is to bring them back to the earth and store them in one place. Now because satellites returns from space, therefore, the satellite debris has to be deposited in a safe place that is away from the population. The location that is used for this task is called Point Nemo and is officially known as “the oceanic pole of inaccessibility.

The word Nemo is derived from Latin which means "no one" and when a place is called "Nemo Point" it means that no one lives there. It is the point in the ocean that is farthest away from land, that is, in the middle of the ocean. Now because no one lives here, the closest islands are also about 2,700 kilometers away and are uninhabited, and it does not even come within the border of any country. The distance and inaccessibility of this place from the populated area are estimated from the fact that even the person who discovered this location has not visited here till date. Hrvoje Lukatela, a survey engineer had located this point in the ocean using a computer program in 1992. Since then, this place has started being used as a graveyard for space debris.
According to an estimate, the debris of about 200-400 space satellites has been dumped here, with Russia being the largest contributor. When the satellites fall from space, the nanosatellites are completely burnt in the sky. But big satellites do not burn completely and after burning half, they are buried in the lap of the ocean. The Russian satellite that was dropped here was about 140 tons and after being in space for more than a decade, when it was dropped, its debris spread many kilometers away. Official warnings are also given before dropping each wreckage to prevent air traffic. Apart from this, a warning is also given on this hypothesis that if there is anyone around, although the possibility of which is zero, should be aware of it.
This point does not even have any marine life, as there is not much possibility of sea creatures here, so there is no fear of damage to any creature or vegetation. However, due to being secretive and away from the reach of people, many mysterious creatures have been imagined in this place. In 1926, the writer H.P. Lovecraft wrote a book on this scary part of the ocean, "The Call of Cthulhu," which was based on a sea monster. But till now scientists have not seen any such monster at this place.
