China has lost all control of the station, experts have concluded, based on the fact that its initial vague prediction that the behemoth station will fall some time in late 2017 has already come and gone.
Earlier estimates had given a wide window for when the defunct space station the size of a school bus would fall to Earth.
ESA said Tiangong-1 ceased functioning in March 2016 and scientists on Earth no longer appeared able to control it.
Still quite low. It'll come down in the latitudes of 43 degrees north and south, and that is somewhere between southern France and Hobart. Graph at left shows population density.
The European Space Agency (ESA) also predicts an April 1 re-entry, although it notes that it could change. "A more detailed predicted re-entry region will be provided a few days prior to the re-entry time frame", it says. Aerospace Corporation has created a dashboard the gives up-to-date information on the space station's location. According to Aerospace Corp, Tiangong-1 hit the surface between March 30 and April 2.More news: Stillwater police fatally shoot man said to be armed, suicidal
Fortunately, most of it will burn up in the atmosphere.
According to reports it was supposed to have a "controlled re-entry" back into the Earth's atmosphere.
Markus Dolensky, technical director of the International Center for Radio Astronomy Research in Australia, said witnesses to the Tiangong-1 descent should see a "series of fireballs" streaking across the sky - provided there were no clouds.
The space station has been slowing down and when it can't go fast enough to stay in orbit, it will reenter the earth's atmosphere.
In fact, in decades of space exploration there is only one recorded instance of a person being struck by space debris.

At the time, Harvard astrophysicists told The Guardian that "the debris wouldn't do widespread harm but a large piece could seriously damage a property, or if it landed in a crowded city", Mashable reported.
