Tiangong Station 1 was launched in 2011 as one of the great hopes of China's ambitions in space, and as part of its plan to show itself as a global superpower.
But last year scientists at the Chinese space agency CNSA said they had lost control of the laboratory, and are now heading to Earth. The statement ended months of speculation, as experts who observed the station's streets said the station had behaved strangely.
And it also sparked fears that people on land could be at risk from the debris of falling outer space. There is a possibility that no one will be hurt by the station's collapse because it is likely that the laboratory will fall overboard. But there is also the possibility that the station is falling near people.
It is very difficult to predict where it will fall because the technician has lost control of the capsule, and the station will be thrown by the wind as it descends. Even the slightest push of the weather can send it from one continent to the next.
Most of the debris will burn on the way to Earth's atmosphere. "But a 100kg cut will pierce and fall from the sky," McDowell said.
