It could re-enter for a crash land anywhere between 43 degrees north and south of the equator, which is a huge swath of land and ocean stretching from the northern contiguous United States to Tasmania in the south. Congratulations, for Canada, you people are totally safe except for a little piece of Ontario.

As the Aerospace Corporation explains, the density of the atmosphere, uncertainties in the physical changes of the space station over time, and uncertainties in the exact location and speed of the spacecraft (due to ground control's loss of communication with the object) may cause the time and place of its fall to be farther away from predicted dates than scientists anticipate.

After months of calculations, experts have been able to narrow down the window during which the Tiangong-1 space station and laboratory will fall back to Earth.

'This forecast was updated approximately weekly through to mid-March, and is now being updated every 1~2 days'.

Tiangong-1 and Tiangong-2, launched in 2016, were missions created to be stepping stones to a large, modular Chinese Space Station, with the core module set to be launched in 2020.

This window is "highly variable", not ironclad, Space Debris Office representatives stressed in the updated forecast, which was issued yesterday (March 21). While many scientists believe most of the object will burn up while entering the atmosphere, there is still a chance some debris makes its way all the way to the ground.

'It takes longer to cross at these latitudes, which is why it has a higher risk of coming down here'.

The rest of us will see mainly rain but it will become heavier through the evening before finally tapering off in the morning. Areas along the Virginia border and northwestern mountains look like a safe bet for up to a few inches of snow accumulation.

The Tiangong-1 was China's first prototype space station.

The space station, which was originally set to be decommissioned in 2013, according to Reuters, is in a degrading orbit that might lead it to an imminent crash on Earth.

Trackers have been keeping a close eye on Tiangong-1's whereabouts for a while now. But it's impossible to predict exactly where or when the unsteerable terminal will land.

The space lab, named "heavenly palace", is still in orbit.
