The NASA Research Satellite said that the Planetary Satellite (UARS) will descend at 8 km / sec and fall to any place in the area between 57 degrees North and 57 degrees South of the equator. . It is an area with a high population density, but the risk of satellite damage is only 1 / 3,200, because most satellites will break or burn before touching the ground.
UARS artificial satellite stopped operating in 2005.
NASA scientists identified 26 fragments that could fall to the ground. They can be scattered in an area of 400 to 500km width. NASA said its scientists could only accurately predict the satellite's fall position about two hours before it entered the atmosphere.
The Space Shuttle Discovery brought UARS (more than 6 tons) into orbit in 1991. It stopped working in 2005. Residents are not allowed to keep or sell UARS fragments, because they are still assets. of the US government.
The most recent fall of the artificial satellite occurred in 1979. At that time, Skylab , a satellite with a mass of 15 times the UARS, plunged into western Australia. The Australian government has asked the US government to pay a mere 400 dollars to clean up the satellite fragments.
