Space analysts have determined that China's out-of-control Tiangong-1 space station will likely fall to Earth sometime between December 2017 and March 2018.
The timeline was estimated last week by a group called the Aerospace Corporation.

Senior staffer Andrew Abraham said: "We receive orbital data from the Joint Space Operations Center... on a daily basis.
"We have been monitoring this data closely and perform re-entry calculations on a regular basis to monitor any changes in the space stations orbit or decay rate."
This model suggests that re-entry may occur slightly after the 2017 timespan that was originally at a news conference last year.
Regardless of when it happens, space experts have stated that the event is unlikely to pose a threat to people or property on earth.
One official said: "Based on our calculations and analysis, most parts of the space lab will burn up during falling."
