The sun is slowing down the fall of the Chinese Tiangong 1 space station. These days the biggest and most famous star has made the atmosphere so rarefied and quiet as to slow down the descent of the Chinese Tiangong 1 space station towards the Earth. The impact with the atmosphere, initially scheduled for the dawn of Easter, has now slipped to the hours between the Easter evening and Easter Monday morning. The most recent estimates, based on data from the Italian Space Agency (ASI), indicate as the most probable moment for the return of the 2.34 in the morning of the 2 April. Because of this slow descent it was impossible to have the elements to begin to exclude some areas from areas where re-entry into the atmosphere could take place: consequently the potentially risky band continues to be the vast one, included between 43 degrees of South latitude and 43 degrees of north latitude. It is one of the most populated areas of the Earth, just think that it includes cities like Los Angeles, New York, Rio De Janeiro, Madrid, Rome, New Delhi, Sydney, Hong Kong and Tokyo, said Tommaso Sgobba, director of international association for space security Iaas (International Association for the Advancement of Space Safety). As for Italy, the probability that the re-entry into the atmosphere of the Chinese space station continues to be very low, equal to 0,2%, have made known the experts of the ASI who are part of the technical table coordination table between Civil protection, Enac, Enav, Aeronautica Militare and Difesa. To begin to exclude some areas from the large strip that extends from South America to Australia, we need to wait for the space station to drop a little further. Currently the Tiangong 1 approaches the Earth at the rate of ten kilometers a day because on the Sun there are no eruptions that, throwing charged particles towards the Earth, make the outer layer of the atmosphere more dense, that is the thermosphere, which extends up to the share of 500 kilometers. "When there is no solar activity the atmosphere is rarefied for many hundreds of kilometers above the Earth and this phenomenon slows the fall of the space objects.
