A Chinese rocket lost in space sows fear on Earth

The US Department of Defense expected that the Chinese missile that is orbiting in space will fall to the ground tomorrow (Saturday), without specifying until now where it will fall, and whether it will be on land or over the ocean.
Pentagon spokesman John Kirby said during the daily press conference, the day before yesterday (Wednesday), that Defense Secretary Lloyd Austin is aware of the reports about the Chinese missile, and that the Space Forces Command is following the path of its wreck, whose main body appears to be almost intact, and it may fall in Somewhere on this May 8th. But he added that it is too early to know the location of its fall or the nature of the precautionary measures that must be taken, before determining the area of ​​its entry into the Earth’s atmosphere. Despite the fears raised by the fall of the missile above the ground after Beijing lost control of it, it is not the first time that man-made objects flying in space have fallen above the Earth. A CNN report said that the expected debris may not pose a major threat to public safety.
It quoted astrophysicists as saying: “It will not be the end of the world.” The weight of the Chinese missile debris is about 20 tons, which is the empty part of the missile, and it is considered the largest piece of space that will fall freely on Earth since 1991. And the fourth largest piece to fall on Earth. But the Chinese missile renewed the debate between the authorities, the countries that launch their missiles and vehicles in space, and environmentalists about the danger of these objects falling to life.
Studies indicate that the outer space surrounding the Earth has become inhabited by thousands of pieces of debris, which threaten safety both on the surface of the earth and in space. These studies indicate that although most uncontrolled space debris is subjected to combustion upon entering the atmosphere, before colliding with the Earth, large parts such as rockets may fall relatively completely over populated areas. According to the report, last year one of the largest pieces of space debris fell in the Atlantic Ocean, after passing in a direct line over Los Angeles in the western United States and east of New York.
As for the pieces that fell above the ground and are larger than the Chinese missile, they were from the “SkyLab” space station of NASA in 1979. A piece of the “Skylab” missile in 1975, and the Russian satellite station “Salyut 7” in 1991. The report adds that these Accidents are few, because space agencies around the world try to avoid leaving large objects flying in Earth’s orbit, by pushing them out of orbit, in order to avoid their fall to Earth. One of the experts explains that there are no rules, controls, or international law that govern dealing with space debris, calling for stressing the need to make efforts “so that we do not leave our waste in orbit in this way.” He pointed out that the Chinese missile is designed in a way that leaves large pieces of it in a low orbit, and this is not good compared to what other space agencies do that avoid it.
According to the report, the debris floating in space is estimated at 9,000 tons of scrap, equivalent to the weight of 720 school buses, and hundreds or millions of objects orbiting in an uncontrolled orbit. This includes parts of spent missiles, disrupted satellites and debris from military demonstrations of anti-satellite missiles that countries such as China and Russia are testing, and are concentrated especially in orbits close to Earth. Although this debris does not directly affect the Earth’s population, it greatly affects the satellites working to provide services such as weather and climate tracking, land, marine and space navigation systems, as well as the International Space Station or stations of some countries.
And while there were about 1,000 satellites years ago, there are now more than 4,000 orbiting Earth. What adds to the size of the problem is that experts and specialists in space sciences do not have an accurate map of this debris. Potential collisions are tracked using sensors to estimate where they have fallen.
