dryriver writes: China launched a space laboratory named Tiangong 1 into orbit in 2011. The space laboratory was supposed to become a symbol of China’s ambitious bid to become a space superpower. After two years in space, Tiangong 1 started experiencing technical failure. Last year Chinese officials confirmed that the space laboratory had to be scrapped. The 8.5 ton heavy space laboratory has begun its descent towards Earth and is expected to crash back to Earth within the next few months. Most of the laboratory is expected to burn up in earth’s atmosphere, but experts believe that pieces as heavy as 100 kilograms (220 pounds) may survive re-entry and impact earth’s surface. Nobody will be able to predict with any precision where those chunks of space laboratory will land on Earth until a few hours before re-entry occurs. The chance that anyone would be harmed by Tiangong-1’s debris is considered unlikely. When NASA’s SkyLab fell to earth in 1979, an Australian town fined them $400 — for littering.
