China had put Tiangong-1 into orbit in 2011. The Chinese space station completed its mission two years ago, but still, it failed to fall back to the Earth. In 2016, China confirmed that it had lost the ability to control the behavior of the satellite and therefore, cannot confirm where will it crash.
The European Space Agency (ESA) said that the Tiangog-1 might end up anywhere between 43 degrees North and 43 degrees South. It is estimated that the re-entry will take place between 30th March and 2nd April. However, it has been said that the given timeframe is highly variable. A proper forecast can be given on the weekend.
The space station is slowing coming close to the earth. The descent will gradually pick up speed as the atmosphere gets thicker than before. Most of the station will burn up when it gets close to the Earth due to heating up. Dr. Elias Aboutanios has said that it cannot tell how much part of the space station will survive because China has not revealed anything about the makeup of Tiangog-1.
There is nothing t be worried about because most of the parts of the space station will disintegrate. Even if some part of it survives like the rocket engine and the fuel tank, the chances of it hitting anyone are very slim. Most of the debris anyway falls back to the ocean.
