At some point between March 30 and April 2, Tiangong-1 will re-enter the Earth’s atmosphere, and most of the space station’s components may be burned out. However, thousands of pieces of debris may “surviveâ€, and the result will be Will fall on the surface of the earth.
In 2016, China's manned space project officially stated that the Tiangong-1 experimental module launched by China has officially ended its mission and mission, and will fall into a satellite cemetery in the South Pacific after terminating data transmission.
The European Space Agency and the Russian Space Agency have previously announced that they will closely track China’s Tiangong-1 experimental module to prevent any accidents. It also estimated the time and place of entry into the atmosphere, without mentioning the news that it would hit the ground.
And the probability of us being hit on the head by any of these fragments is very low, about 1 in 292 trillion, which is one million times lower than the probability of winning the first prize in the lottery. At present, it is estimated that the potential landing area of ​​the space station accounts for about one-third of the earth, and most of the area is water.
However, if you really happen to find a piece of Tiangong-1 fragment, I suggest you not touch it.
Experts said: “There are two reasons why it is not recommended to contact space debris. The first is health risks. The space station may carry a variety of hazardous materials that are harmful to humans. This includes fuel tanks containing toxic fuel. In addition, because these debris pass through the atmosphere Polished, so the edges may be very sharp."
In addition, keeping the fragments privately may also get you into legal disputes.
Pearlman said: "According to the 1967 Space Treaty, a country’s spacecraft is their legal property, no matter where it lands, whether it falls into the ocean under the sea, or it is on its own land or on the land of other countries, it is Belongs to that country of origin."
"After the Challenger exploded in 1986, a gentleman from the Coast Guard kept a spacecraft fragment for 25 years," Pearlman said.
"He is the chef on the investigation ship, and his sailors are helping to repair the debris. He decided to use a bucket to shovel the tiles floating in the water and save them on himself. 25 years later he decided to go on eBay Sell ​​the pieces."
In the end, his auction behavior was discovered by the National Aeronautics and Space Administration, and he was arrested. He can be fined up to $10,000 + imprisonment for 10 years. But in the end he was convicted of stealing government property and sentenced to only two years of probation.
