Probes operating in geosynchronous orbit – a space area about 36000 kilometers (22370 miles) above the earth’s surface – is responsible for providing a range of important navigation, communications and weather services that may be threatened by debris that is too small or too dark to be easily tracked. It seems that the unremitting efforts of human technological progress will inevitably pay a heavy price for the natural environment we conquered along the way. Plastic is everywhere on land and sea, and air travel has become a major source of pollution for the once pure sky. Industrialization has led to the wanton destruction of habitats and is now fundamentally changing the earth’s climate. It has even put our future at risk. Humans are now slowly moving into self-protection and seeking ways to control their pollution. < / P > < p > and all of this is reflected in our expansion into space. Since we began to put rockets into orbit in the 1950s, the spread of man-made garbage around the earth has continued to increase. Orbital debris is made up of old, no longer existing satellites and rockets that put them there. They come in different sizes, from paint flakes to giant fairing. In February 2009, the worst-case scenario occurred when two large decommissioned satellites, commercial iridium 33 and Russian military owned kosmos-2251, collided with each other, creating a large number of dangerous debris clouds. Fortunately, the aerospace industry is developing a new strategy to track and one day derail troublesome debris, and guidelines have been developed to reduce the influx of new debris for future launches. The U.S. strategic command has the most thorough record of orbital debris. Its fleet of more than 30 ground observation stations and six satellites regularly updates the information. The strategic command can track objects as small as 1 meter (3 feet) in diameter. However, their records are far from complete. < / P > < p > the new survey focuses on debris in geosynchronous space about 36000 kilometers above the earth, which is part of the debriswatch collaboration between the University of Warwick and the national defense technology laboratory. < / P > < p > researchers look for small or non reflective fragments that reflect very little light and are not usually found. Images collected during the survey by the 2.54 m (8.3 ft) Isaac Newton telescope on the island of La Palma, off the Moroccan coast, were run through specialized software capable of identifying and describing potential debris fragments. By analyzing the light signals of tumbling objects, scientists can understand their size, shape and other surface properties. < / P > < p > space debris whistling through the low earth orbit will gradually slow down due to the resistance of particles in the earth’s atmosphere, and eventually lead to their derailment. However, at high altitudes in geosynchronous space, there is no atmospheric resistance, so debris left in this area is likely to remain there, which can become a serious problem over time. < / P > < p > about 95% of the debris is estimated to be about 1 meter or less, making it more difficult to reliably monitor and match known objects in the U.S. Strategic Command database. Of all the objects found in the survey, including objects over 1 meter, more than 75% of them were found to be unknown. < / P > < p > after the problem was identified, the team called for more regular surveys aimed at identifying and describing threats in geosynchronous orbit. The data from the new study will help scientists develop and upgrade algorithms for analyzing the optical fingerprints of distant space debris to gain a deeper understanding of the threat outside the earth and its specific behavior. < / P > < p > for now, orbital collisions are still very rare, although the international space station has to be moved to a new temporary orbit from time to time to avoid oncoming debris or wrong satellites, as this week did. It is an important step to make space safer to strengthen the observation of debris inside and outside low earth orbit. However, the spread of rocket technology means that we will see an increase in space waste in the coming decades, followed by an increase in the threat to important infrastructure satellites.
