An old NASA telescope will fall to Earth soon. AP The spacecraft, which weighs about 1.5 tons, is losing altitude and will soon enter the Earth's atmosphere. 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. At the same time, the potential fallout area covers Africa, Australia, India, Southeast Asia, Central and South America. rights.az Contact
