Ranking the Criteria for Assessing Space Debris Removal Technics by BMW and FUCOM Methods

Space debris refers to man-made objects that are orbiting Earth but no longer serve a useful purpose. This includes items such as defunct satellites, spent rocket stages, and other debris from space missions. Space debris can range in size from tiny flecks of paint to large satellites, and they can pose a threat to operational spacecraft and satellites, as well as to human life on Earth. As more and more satellites and spacecraft are launched into space, the amount of space debris has increased, and it has become a growing concern for space agencies and governments around the world. Some measures are being taken to reduce the amount of space debris, including designing spacecraft to be more easily deorbited at the end of their useful life, and launching cleanup missions to remove some of the largest and most dangerous debris. Over time, the amount of space debris has increased significantly, and it can pose a threat to active spacecraft and satellites. In this study, we examined the space debris removal methods, and the most important criteria scientists must consider before a space debris removal mission. We determined 9 different and important criteria for space debris removal missions then we consulted three different experienced people who have played role in space studies past 20 years to subjectively rank each criterion in order of importance. As a result of these analyzes, we listed the most essential and least essential criteria for space debris removal missions, using BWM (Best Worst Method) and FUCOM in our calculations.
