Although experts have not yet determined exactly where the out-of-control module will land, an Aerospace report detailed that it will likely re-enter somewhere in the northern USA states, parts of South America, northern China, the Middle east, central Italy, northern Spain, New Zealand, the south of Africa or Tasmania in Australia.
Tiangong-1's name means "heavenly palace". It was designed as a prototype craft, a precursor to China's ambition of a permanent, 20-tonne space station still expected to launch around the year 2022.
The science of where the station will hit is notoriously inexact because small changes in "space weather" - the effect on the Earth's atmosphere of flares of electromagnetic radiation and charged particles travelling as solar wind - can shift its trajectory drastically.
The US-funded Aerospace Corporation estimates Tiangong-1 will re-enter the atmosphere during the first week of April, give or take a week, while the European Space Agency (ESA) says its best guess is the module will come down between 24 March and 19 April.
ESA has said that Tiangong-1 will "substantially burn up" in Earth's atmosphere.
"When considering the worst-case location the probability that a specific person will be struck by Tiangong-1 debris is about one million times smaller than the odds of winning the Powerball jackpot", states the report. The Tiangong-1 station has been making headlines since China ceased communications with the spacecraft back in 2016.
'Potentially, there may be a highly toxic and corrosive substance called hydrazine on board the spacecraft that could survive reentry.
"In the history of spaceflight no known person has ever been harmed by reentering space debris".
The geographical range of where it will touch down is still completely uncertain, with the final spot extending from 43 degrees North to 43 degrees South latitude.
Jonathan McDowell, an astrophysicist from Harvard University, seems a bit less anxious about the satellite than some, but he still has a note of caution, as he told The Guardian. Jonathan McDowell, an astrophysicist from Harvard University has said such debris keep crashing every few years but this one is bigger in size and speeding size is more so the exact details are being tabulated yet. Liu Yang was the first Chinese female astronaut who visited there in 2012. China's first space station will come into collision with our planet within weeks. Before that, in 1991, the last uncontrolled return was Salyut 7 - or Cosmos 1686 - weighing 40 tonnes. If look into some past incident, no person has been died till now due to space debris.
A huge Chinese space lab is out of control and about to crash to Earth in a fireball - and debris full of toxic chemicals could fall on Europe, experts have warned.
