Chinese space station will fall to Earth within two weeks

China's first space station may fall to the ground as soon as one week from now, and certainly within two, orbital debris experts with the European Space Agency (ESA) say. Scientists, however, still cannot predict with any confidence where pieces of the 10.4-meter long Tiangong-1 station, which is traveling at 17,000 km/h, will land.

 

The latest estimate from the ESA indicates the station will enter Earth's atmosphere between March 30 and April 3, at which time most of the station will burn up. However, the station is large enough—it weighed 8.5 tons when fully fueled but has since used much of that propellant—that some pieces will very likely reach the planet's surface.

 

Beyond the fact that the station will reach a final impact point somewhere between 42.8 degrees north and 42.8 degrees south in latitude and probably near the northern or southern extremity of those boundaries due to Tiangong-1's orbital inclination, it is not possible to say where on Earth the debris will land. However, the likelihood of it affecting humans is quite low. Scientists estimate the "personal probability of being hit by a piece of debris from the Tiangong-1" is about 10 million times smaller than the annual chance of being hit by lightning.
