"Space Harpoon", a new device to clean up space junk.





Many countries are now competing to become a superpower in space. This resulted in a huge amount of space debris scattered around the earth. Most of which are very small. But even as small as a bolt or nail head Can cause a lot of damage when moving at high speed.Scientists estimate that There are millions of tiny pieces of space ทางเข้าjoker junk floating around the world today. They range in size from less than a centimeter to about 10 centimeters, weighing approximately 7,000 tons, many of which move at high enough speed to damage satellites, spacecraft, space stations, and even the astronauts that leave. Operating outside the spacecraftFor this reason, scientists are trying to come up with a way to clean up those space junk.The "Space Harpoon" is the newest tool that RemoveDEBRIS scientists have developed and developed. To clean up space junk floating in orbit around our planet.Simon Fellowes, a British scientist for the RemoveDEBRIS program, said that a large amount of space debris was generated from past launches of spacecraft and satellites. May create problems for new spacecraft That are traveling into spaceMr Simon said that if two pieces of space debris collide while moving at high speed in space. May cause a lot more debris from that collision. Which moves at several times more speed And possibly as fast as 17,000 km / h.This scientist explains that The space harpoon will be fired from a spacecraft or a launcher. Targeted is a large piece of debris floating outside the Earth, such as the remains of an old satellite. At a speed of about 20 m / s, it can penetrate through the plaque of those debris. In the same way as shooting a harpoon to catch fish swimming in the water.Then the harpoon will reap, seize, and retrieve the waste. And sent back to the surface of the earth for further decompositionSurray Satellite Technology's KT Bashford said space debris capture technology is critical in solving the problem. Because in addition to being able to immediately be used to trap debris in space It will also stimulate the thinking process of researchers to develop the best possible devices or methods to tackle the problem of space debris in the future.This time, in addition to the space harpoon Researchers are also conducting experiments. 'Space net' to be used to trap various debris as well.
