Weather of Arabia - With the approaching date of the Chinese missile debris entering the Earth's atmosphere (between July 30-31), we will answer several inquiries we received in this regard.
When the body of the Earth's atmosphere enters it, it begins to burn as a result of the high speed at which it rubs with the particles of the atmosphere and the presence of air, and usually 20%-40% of the mass of the body survives burning to reach the Earth's surface, this means that there are four to nine metric tons of debris mass (Mass is about 22 tons) It can reach Earth. Last year, the debris of the Chinese missile that returned to Earth out of control was very large, but a lot of debris was over the ocean and did not cause any damage.
Re-entry operations of Chinese missile debris can be visible from the ground if the re-entry site and timing are appropriate. And if it happens in a populated area, it should be dark as it is easy to see the glowing pieces of debris as they descend from space.
The scene will be similar to the image (below), which shows the return of the ATV-1 spacecraft in February 2015 (photo courtesy of the European Space Agency).
How do weather patterns affect the return path? Is this why it is so difficult to calculate exactly where it will land?
Sun activity, such as solar flares, is one factor that influences the accuracy of predictions of when and where space debris will return. The sun sends out a lot of energy that heats the Earth's atmosphere. If the amount of energy changes even slightly, as with a solar flare, the atmosphere will expand or contract - and the amount of drag it pulls the object into space will change, affecting the accuracy of the return timing, and it is known that accurately predicting what the sun will do is very difficult, so it is difficult to accurately predict when An object enters the Earth's atmosphere.
