An old NASA telescope weighing 1.5 tons will soon fall to Earth, AP writes. Most of the telescope will burn up on re-entry. However, individual parts are made of tungsten, which is denser than lead, as well as fragments of mirrors can reach the surface of the Earth. It is likely that the debris will fall into the sea.
