British scientists have developed a type of artificial satellite dedicated to the removal of space trash. This is what we call the space "cleaner". It can help solve the headache of space trash. The mass of the space "cleaner" is only 6 kg. The total cost of manufacturing and launching is less than 1 million U. S. dollars, don't look at it as small, it is not small, it is equipped with 4 cameras for searching up and down, left and right, front and back. When you see space trash, it Immediately approached, and then grasped the "trick or treat" tightly, and then forced the space junk to slow down the flight speed with itself and reduce the height under the effect of gravity. Once it entered the dense atmosphere, the high temperature caused by the fierce air friction caused Them will be burned together. From the ground, it is like a falling meteor in the sky. If the volume of the garbage is too large to be completely burned in the atmosphere, the "cleaner" can also control the landing time and let its debris fall to the desert. Or in the ocean, it will neither threaten the spacecraft in the air nor cause trouble to the people on the ground. What is wrong with the above materials? ['The main content of this material is to explain the characteristics of space "cleaners" and their uses.', 'Space "cleaners" rely on its own equipped cameras to search space trash from multiple directions.', 'Space "cleaners" can control landing time during the process of burning with space trash.', 'Space "cleaner" is light in weight and low in cost, so it can be burned with space trash entering the dense atmosphere.']
