All of this space junk could pose a threat to satellites in operation, and new research suggests that the problem may be much more serious than previously thought. < / P > < p > astronomers at the University of Warwick tried to cross reference orbital debris detected in geosynchronous orbit with objects in the public satellite catalog. They found that more than 75% of the fragments did not match. James Blake, a Ph.D. student in physics, said in a statement: “a lot of dim, undocumented pieces seem to be rolling. We need to further detect these weak fragments and get more data to better understand the situation outside. ” < / P > < p > the man-made debris in orbit may be the debris of abandoned satellite or rocket, or even deteriorated insulation material or paint debris. Sometimes large pieces of space debris collide to create more small pieces, which increase the threat. In a frictionless vacuum, objects can rotate around the earth at speeds of thousands of miles per hour, and even small objects can cause serious damage after impact. < / P > < p > just this week, the ISS’s orbital altitude was much lower than that of the survey area, and it conducted an evasion operation with an unknown space debris approaching. < / P > < p > “it is important that we continue to look at the geosynchronous region with as large telescopes as possible, so as to begin to build a more complete sense of the weak debris environment,” Blake stressed. It is said that “gta5” will be launched on Google cloud game platform stadia
