Back in September 2016, China made an announcement stating that it had completely lost control of its Tiangong-1 space station and according to their calculations it would crash down to earth between December 2017 and March 2018.
Recent calculations by the European Space Agency have put the crash date between March 24th, 2018 - April 19th, 2018. The re-entry will reduce most of the space station and its components to ashes but some of the more resistant components might indeed succeed to make it all the way to the surface.
The predicted area of re-entry into the Earth’s atmosphere is believed to be between 43 degrees north and 43 degrees south latitudes, which leaves us in a very helpless state to pinpoint the exact location of the crash. All we know is it will crash in one or many of these places - the US, parts of Spain, Portugal, Greece, China, Middle East, and a couple other countries of the northern hemisphere.
It has officially been confirmed by China that some of the debris might contain toxic chemicals and worry that if it succeeds to penetrate the surface of the Earth’s atmosphere, it could cause lasting damage once it hits the ground
It is a constricting thought that a superpower like China lost control of an 8-ton space station. In any case, all the space agencies around the world will monitor the trajectory of the runaway space station. Either way, this will be a valuable lesson learned by all the major space agencies around the world.
