Berlin (ap)-the atmosphere of the collapse and its satellite is expected to fall to in a few hours to crash the earth, the German aerospace centre, said Sunday morning.
Yinpian ROSAT research satellite is expected to reach the European time on Sunday morning, or about 0030 and 0530 GMT (the United States at 8:30 eastern time this afternoon (Saturday) at 1:30 eastern time on Saturday) between, the agency said.
Van in most of the size of the satellite, is expected to back into the burning up in the atmosphere, but as many as 30 weighing 1.87 tons (1.7 tons) of debris into the earth may speed can be as high as 280 miles (450 kilometers).
The satellite's orbit every 90 minutes, it can along the way of it, in almost any place play-53 degrees north and 53 degrees south, including polish, including North America, Europe, South America in some areas of the planet of the broad masses of the outside of the large, Africa and Asia.
"According to our data, we now have in the hope that it do not hit, more than Europe, Africa and Australia, agency spokesman andreas Schuetz said." "this satellite is still in orbit, we look at the data in other parts of the world," he added.
Scientists are no longer able to communication and death satellite in where, it will come down, but difficult to predict the sun's activity rendering fluctuation and the facts.
2.69 tons (2.4 tons) science ROSAT satellite is launched in 1990, and in 1999 after retirement, is used for research into black holes and the neutron star and executive first all the sky imaging telescope X-ray source investigation.
ROSAT the largest single segment may touch the earth heat mirror of the telescope.
During the mission, the satellite's orbit about 370 miles above the surface of the earth is 600 kilometers, but since it has lost its retired the height, hovering in the distance is only 205 miles above the ground such as June (330 kilometers), the agency said.
Die NASA satellite fall in southern Pacific last month and causes no damage, although people worry it will hit the residential areas, cause harm or kill people.
Experts think, from bus-sized satellite about 20 pieces of metal fell more than 500 miles (800 kilometers) no one living in the part of the world span.
NASA climate research satellite into the earth's atmosphere, higher than American Samoa. But does not drop, because it the disintegration of the debris hitting another 300 miles (480 kilometers), north east, south west water Christmas island.
Scientists had previously said, it is possible to Canada works has some northwest.
Germany's space agency of the earth somewhere in the odds of someone 1 satellite damage-2000-slightly higher than the risk level of calculation for NASA satellite. But knock on any one of the odds are 1 14 trillion dollars, there are 700 million people on this planet.
