Although they cannot predict where the flaming debris will land, they think it will hit over the Easter weekend, between March 30 and April 3.
According to experts tracking the station, the satellite has the highest chance of crashing along a narrow strip around latitudes of 43 degrees north and south.
This includes a number of highly populated cities including New York, Barcelona, Beijing, Rome and Toronto.
The agency’s Space Debris Office, based in Darmstadt, Germany said: “At no time will a precise time/location prediction from ESA be possible.
“This forecast was updated approximately weekly through to mid-March, and is now being updated every 1~2 days.”
The doomed 8.5tonne space station has been hurtling towards earth since Chinese scientists lost control of it in 2016.
