Tiangong 1 (Heavenly Palace) is predicted to crash into our planet on April 1, give or take a few days.
South Australia is in the potential crash zone.
The 8500kg, bus-sized floating laboratory was launched in 2011 and the last astronaut abandoned ship in 2013.
China has denied the station is out of control, but almost everyone else says it is floating in a most peculiar way.
Last year China told the United Nations’ Committee on Peaceful Uses of Outer Space that it was set to re-enter the atmosphere this year.
It is difficult to predict exactly when or where it will land — the European Space Agency says it will be this weekend while China’s space agency says it could be as late as Wednesday.
Estimates of the crash zone include everywhere except for Russia, Canada and Northern Europe.
Ground control authorities say any injuries are highly unlikely and the station will mostly break up on re-entry.
The Tiangong-1 Chinese space station is likely to smash back down into Earth sometime this weekend.
The surviving pieces will probably fall in the ocean, or in uninhabited places.
There is a low chance anything will hit Australia and an even lower chance it will hit you — the chances are about one in a trillion,
Dr Alice Gorman, a space archaeology expert from Flinders University, says if anything survives it is likely to be the fuel tanks.
“The big question is whether any parts of the space station make it down to the surface of the Earth intact,” she told the Australian Science Media Centre.
“The most common spacecraft parts to survive the heat of re-entry are those with the highest melting temperature.
“These are titanium pressure vessels — called space balls — and fuel tanks. Tiangong 1’s fuel tanks are a steel alloy, so they may survive.”
China is liable under the Outer Space Treaty if anyone does get hit.
In 1979, when NASA’s Skylab landed in Western Australia, NASA advertised for compensation claims and no one came forward — although a local shire invoiced NASA for littering.
If you are out hiking over Easter and come across something that looks like it might have come from space, steer clear. There were potentially toxic substances on board.
The good news is we could get a spectacular night-time show as Tiangong 1 burns up and becomes zigzagging stardust.
