Space waste refers to all kinds of waste formed during the operation of the earth's orbit, such as abandoned satellites, rockets, spacecraft, etc. This not only occupies limited space resources, but also seriously threatens the lives of spacecraft and astronauts in orbit. In recent years, the high activity of human activities has triggered a large amount of space junk, which has brought great harm to the space environment.
China and the International Space Station are both important carriers of human space missions and highly dangerous targets for space junk disposal. During the Shenzhou-17 manned mission, the China Aerospace Center announced that its "solar wings" had been hit by several space particles and had been slightly damaged. At the same time, in December, the space station also unveiled a piece of the first that showed problems such as solar panels being damaged and warming up due to space debris. The harm caused by space junk cannot be ignored.
So why do debris in space crash into space? Was it intentional? Actually, everyone is wrong. Due to various influences such as the earth's gravity, sunlight pressure, atmospheric resistance, etc., its speed can reach several kilometers per second. Therefore, it is very difficult to avoid the space station. In addition, space junk varies in size, some can be detected by radar, while others are small and difficult to detect. Although these tiny particles may seem inconspicuous, the power contained in them is very huge, and once they hit the space station, it will cause huge damage to the space station and even endanger the lives of astronauts.
So, is there a way for humans to deal with space junk? There is no good way to do this. Although there are some similar ideas, such as laser incineration and mesh bag collection, these are only theoretical and difficult to implement. Moreover, this method can only deal with a small part of the garbage, and it cannot eliminate it at all. Therefore, in the face of these "wastes" in space, people really have no way at all.
So, as humans continue to send space vehicles into space, we will see more space junk that will pose a danger to operating spacecraft. In order to reduce the generation of space garbage, promote the production of space garbage, maintain the space environment, and ensure the safety of the space environment, it is of great practical significance.
At the same time, let us praise these people who are fighting in the universe, they are really hard, they are heroes in the universe, they are the pride of mankind, they are the greatest existence in human life, a great existence that dedicates their lives to the universe, and it is also a very hard thing, they have to face countless tasks every day, and they may even encounter threats to their lives. Moreover, such a large aircraft needs to be repaired in space, and you will often have to go to space to carry out maintenance work in the future.
