Paris, April 1 (IANS) The European Space Agency (ESA) has said that the Chinese defunct space lab, Tiangong-1, will re-enter Earth’s atmosphere on Sunday night.

The Paris-based agency, which is managing the international campaign to follow the laboratory’s fall, said on Saturday that the time and place of its re-entry continues to be a “highly variable” prediction affected by the changing solar activity, reports Efe news.

According to the agency, the chances of someone being hit by a piece of the space lab is 10 million times less than the annual probability of being hit by lightning.

ESA, which has a department specialising in space debris, recalled that at first the space ship’s controlled re-entry into Earth’s atmosphere was planned once its useful life was over, but Tiangong-1, which was launched in 2011, stopped functioning in March 2016.

Its re-entry into the atmosphere, therefore, will not be controlled and according to the latest calculations, it could occur between the latitudes of 43 degrees north and 43 degrees south, which includes a large part of the planet.

The Tiangong-1 will disintegrate during its re-entry and only a few parts of it will survive the process and reach Earth’s surface, which, ESA recalled, is largely covered with water or is uninhabited.

The principal part of the space ship measures 10.4 metres long and is made up of two cylinders of approximately the same length, together with two solar panels of 3 by 7 metres each.

Weighing less than 8.7 tonnes, it is much smaller than other objects that have entered the atmosphere in an uncontrolled way in the history of space flights. The record up to now was set by Skylab, which weighed 74 tonnes.
