Chinese Space Station Is Supposed to Fall into Earth On March 30

China’s first prototype station, Tiangong-1, is supposed to fall into Earth at some point between March 30 and April 6. An out-of-control Chinese space station with “highly toxic” chemicals on board may hit a number of major world cities. New York and parts of Europe are among the most likely targets. In accordance with researchers a number of highly populated cities including New York, Barcelona, Beijing, Chicago, Istanbul, Rome and Toronto could also be hit. It is most likely to fall into these places because it is travelling parallel to the equator at the most northern and southern points of its orbit. It is more likelihood that it will crash into cities along a narrow strip around latitudes of 43 degrees north and south. The doomed 8.5-tonne craft, which has been hurtling towards Earth since control was lost in 2016, is believed to contain dangerous hydrazine. Scientists will only know the precise date it will impact and exactly where debris will fall during the finals weeks of its decline. Dr. Hugh Lewis, senior lecturer in Aerospace Engineering at the University of Southampton, explained why this is so, comparing the geometrical processes at work to crossing the road. He said: “Chinese space station is travelling around a more or less circular orbit, which is tipped with respect to the equator at 43°. If you plot this path on a map of the Earth, it produces a sine wave pattern, with the slower curve of the wave in northern and southern latitudes and the faster straighter sections running from east to west”. “When the spacecraft crosses the equator, it’s crossing the road at this point, and it does so really fast. When it goes across the red bands further north and south, it’s crossing at a steeper angle – almost parallel to the road.”
