Satellite weighing more than two tons will fall uncontrollably somewhere on Earth this Wednesday. ERS-2, launched in 1995 as the largest and most sophisticated satellite of the European Space Agency, will end its service by disintegrating in the Earth's atmosphere.

Some fragments weighing up to 52 kilos could survive, and fall on various points on Earth. The chances of someone being injured by the impact of a piece of the satellite is 1 in 100 billion. As well as where it is most likely to fall is the ocean, ESA assures that if any fragment survives, it would not contain toxic or radioactive substances.
