a Rocket Long March-5B, usado no The launch of the central unit of the Chinese space station Last Thursday (29), it returned to Earth in an uncontrolled slope, to reach populated areas in the coming days, according to what you reported. Space News.
After the Tianhe unit was put on OrbitThe driver broke up with him. However, the first phase of Long March-5B also ended in this region from The space For some error, the constant friction with the Earth’s atmosphere dragged it closer and closer to the planet.
Traveling at a speed of 7 km / s, the central stage of the Chinese missile, which is about 30 meters long, 5 meters in diameter and weighs 21 tons, should not burn completely during re-entry, as it usually does with other types Space junk Minors, precisely because of their measures.

Parts of it are expected to withstand high temperatures and fall into an undefined area. The exact location of the fall cannot be determined, as there are many uncertainties involved in calculating the effect of a ship’s atmospheric clouds, such as the expansion or contraction of the atmosphere, caused by the activity of Soul.
The possible path of the object
Although it is difficult to estimate where the Chinese missile will fall as well as to determine the date, the orbital inclination of the object, of 41.5 degrees, indicates its passage slightly north from cities such as New York (USA), Madrid (Spain), Beijing (China) and southern Chile. Wellington (New Zealand), according to the publication.
Its fall must occur at any point within this zone, with a higher probability that the debris will land in the ocean or in unpopulated areas. But the risk warning for the population remains.
According to astronomer Jonathan McDowell, who classified the Chinese Space Agency’s mistake as “unacceptable,” the event would be the largest uncensored return of a spacecraft in recent years.
