BEIJING – China's stalemate and reportedly out of controlspace station is due to re-enter the Earth's atmosphere sometime this weekend. It poses little risk to people and property on the ground, as most of the 8.5-tonne bus vehicle is burned on re-entry into the city, though space agencies are not sure when and where that will happen.
Below are some questions and answers about the station, its reentry and the past and future of.
What will happen and how big is the danger?
The European Space Agency predicts that the station will re-enter the atmosphere between Saturday mornings and Sunday afternoons ̵
The Chinese Agency's latest estimate restores its re-entry between Saturday and Wednesday.
Western space experts say they believe China has lost control of the station. Zhu Zongpeng, chief developer of the China Space Laboratory, denied that Tiangong was out of control, but did not say what China would do to control the plane's re-entry.
Based on the orbit of Tiangong 1, it will come to Earth somewhere between latitudes 43 degrees North and 43 degrees South, or about anywhere across most of the United States, China, Africa, Southern Europe, Australia and South America. Out of reach are Russia, Canada and Northern Europe.
Due to its size, only about 10 percent of the spacecraft will probably be survived on reentry, especially its heavier components such as the engines. The probability of a person being hit by rubble on Earth is considered to be less than one to one trillion.
"This is a big thing the size of a school bus, and most things will only burn in the atmosphere," said Mordecai-Mark Mac Low, curator of astrophysics at the American Museum of Natural History to CBS New York
Ren Guoqiang, spokesman for China's Defense Ministry, told reporters Thursday that Beijing has informed the United Nations and the international community about Tiangong 1's re-entry through multiple channels.
Michigan EOC oversees Re-Entry of Chinese Space Station
Michigan Governor Rick Snyder has launched the State Emergency Operations Center to monitor the re-entry of China's Tiangong-1 Space Station into the Earth's atmosphere
19659002] Aerospace Corp. says it could land along a strip of US that includes the southern lower peninsula of Michigan.
Capt. Chris A. Kelenske, Michigan's Deputy Director of Emergency Management and Homeland Security, says, "The chances are low that the debris will end up in Michigan, but the state monitors the situation and is ready to respond quickly." 19659002] The EOC says that suspicious space debris should be considered dangerous.
