Increasing space debris is becoming a big problem. Now researchers are also saying that the Earth will soon have a Saturn-like ring, which will be made only from the waste that will have been made due to the space programs so far. The ring or ring of Saturn is natural, made of pieces of ice and rocks, that Earth’s ring will be made entirely of space waste, and this problem will increase further with the missions of more countries being sent into space.
Recently, Russia tested an antisatellite weapon, which further strengthened the possibilities of increasing satellite waste in space. NASA and the US government accused Russia of making the problem of space waste more serious by conducting such tests. Due to this test, thousands of different-sized fragments were born in the orbit of the Earth.
Such fragments are increasing the problem of space debris in the geostationary orbit of the International Space Station (ISS) and other satellites. They also threaten the lives of American, Russian, and Chinese astronauts in space. Space waste has become dangerous for the lives of humans, along with the satellites present there. In such a situation, scientists are also doing intensive research on ways to reduce waste in space.
According to a study published in Nature, researchers have also given an option for this. He has proposed to reduce space debris through magnets. Professor Jack Abbott of the University of Utah and his colleagues have presented this proposal. Researchers will collect the waste using magnets. Whereas till now there has been talking of using robots for this. In this technique, it has to be seen that how this waste will be removed after it is deposited.
Abbott says that using robots to collect space debris would be impractical because pieces of this waste would potentially break-even to the robot’s arms. This will create even more garbage. Researchers say that the magnet will prove to be more practical in practice, and there will be no danger of generating more waste. Abbott claims that magnets will be a great solution as they will also clean up garbage that is not made of metal.
According to the European Space Agency (ESA), 170 million pieces of space debris are larger than 1 millimeter in size. While large fragments can collide with a satellite and destroy it, small fragments can also damage the vital systems of the spacecraft. Almost all their pieces revolve around the Earth, and some of them keep falling on the Earth. Earlier this year, a piece of Falcon 9 fell on a farm in Washington state.
Astronomers believe that about 19 thousand pieces (Space Debris) are moving in the Earth’s lower orbit. This orbit is located from 200 kilometers to 2000 kilometers from the Earth. The total waste will be around 7500 metric tonnes, which is equivalent to the weight of about 1100 elephants. Physicist Jonathan Magdoval of the Harvard-Smithsonian Center of Astrophysics says that hundreds of millions of pieces of garbage are not visible on the radar in space but remain a major threat to the ISS and future missions.
