Tiangong-1, known as the "Heavenly Palace", originally launched in September 2011 and was viewed as a major step for the space agency in its quest to build a space station by 2020.
While there's a small possibility that there will be minor damage to a locale on Earth, it's far more likely that the small bits of debris that are left following the Chinese space station's reentry into our atmosphere will fizzle into nothingness.
The exact location of where the space station will hit should become clearer closer to the impact date.
The country's prototype station, Tiangong-1, is due to land back on Earth between March 24 and April 19, according to the European Space Agency (ESA).
In recent days Aerospace, a U.S. research organisation that advises government and private enterprise on space flight, also updated its re-entry window.
The report includes a map showing the module is expected to re-enter somewhere between 43° north and 43° south latitudes.
The chances of re-entry are slightly higher in northern states in the USA, central Italy, northern Spain, northern China, New Zealand, the Middle East and parts of South Africa and southern Africa.
In recent months, the spacecraft has been speeding up and it is now falling by around 6km (3.7 miles) a week.
"Remember that a 1 hour error in our guessed reentry time corresponds to an 27000 km (17000 mile) error in the reentry position", he said in a tweet.
'It is only in the final week or so that we are going to be able to start speaking about it with more confidence, ' said Dr McDowell.
It said: "If this should happen, any surviving debris would fall within a region that is a few hundred kilometres in size".
However, Aerospace insisted the chance of debris hitting anyone living in these nations was tiny.
"There is a chance that a small amount of Tiangong-1 debris may survive reentry and impact the ground", Aerospace reports. But the only ones who know what's on board Tiangong-1, or even what it's made of, are the Chinese space agency'.
"To make any sensible statement about what will survive, we'd need to know what's inside", said Stijn Lemmens, a space debris analyst at the ESA's Darmstadt center in an interview with the Guardian. "Only one person has ever been recorded as being hit by a piece of space debris and, fortunately, she was not injured". NASA says that when it was active Tiangong-1 largely served as a demonstration of the "vital docking technology required for a future space station".
Most of the spacecraft is expected to burn up in the atmosphere upon re-entry.
