European Space Agency says the out of control satellite is expected to hit between January and March 2018... so is Britain safe?

An out of control Chinese space station could smash into a major world city at the beginning of 2018.
The European Space Agency said the 8.5-tonne Tiangong-1, or Heavenly Palace, satellite could hit any spot between two latitude lines in the northern and southern hemispheres.
ESA experts said the 12-metre long craft would crash into Earths atmosphere at some point between January and March 2018.
The UK should be safe, according to ESAs calculations, but New York, Los Angeles, Beijing, Rome, Istanbul and Tokyo are among major cities that could be at risk - although the potential impact area is so large that residents shouldnt be too worried about impending death from above.
Holger Krag, head of ESAs Space Debris Office, said: Owing to the geometry of the stations orbit, we can already exclude the possibility that any fragments will fall over any spot further north than 43ºN or further south than 43ºS.
This means that re-entry may take place over any spot on Earth between these latitudes, which includes several European countries, for example.
The date, time and geographic footprint of the re-entry can only be predicted with large uncertainties. Even shortly before re-entry, only a very large time and geographical window can be estimated.
Although its hoped the craft will burn up in the atmosphere, ESA said some portions of it will survive and reach the surface.
However, it was quick to stress that no human has been killed by space debris throughout the history of spaceflight
Jonathan McDowell, a Harvard University astrophysicist, previously warned there was no way of telling exactly where the space station was going to plunge to Earth.
You really cant steer these things, he said last year.
Even a couple of days before it re-enters we probably wont know better than six or seven hours, plus or minus, when its going to come down.
The station will reduce significantly in size as the Earths atmosphere burns it up.
However, large chunks of metal could still fall to Earth and injure or kill anyone present at the impact site.
McDowell added: There will be lumps of about 100kg or so, still enough to give you a nasty wallop if it hits you.
Reminds me of the excitement when ‘Skylab’ was coming down. The Soviets made threats over any damage to their territory/people.
