A satellite German-sized cars are expected to fall to Earth in a few days. However, it is not known where the satellite pieces would land.
X-ray observatory ROSAT name is expected to fall to Earth between 20 and 25 October with a speed of about 28,000 kilometers per hour. German Aerospace Centre (DLR) deliver it in a statement.
“Final assessment showed that more than 30 individual pieces weighing a total of 1.6 tons will reach the surface of the Earth,” says DLR on its website.
“The timing and location of re-entry (the satellite debris) can not be predicted with certainty,” the statement said, adding that the uncertainty caused by fluctuations in solar activity.
The satellite may enter the atmosphere in three days before or after the range time, DLR said, stressing that the danger to humans is very small.
Last month, NASA said, a U.S. satellite about the size of a bus that slid unexpectedly to Earth across North Africa and the Atlantic before it crashed into the Pacific Ocean off the coast of California. There were no reports of damage when the existence or the Upper Atmospheric Research Satellite (UARS) with a weight of six tons of it fell to Earth.
Two years after the great earthquake that shook L’Aquila, mountain town in the Itala, six scientists and a senior officer on trial on charges of failing to issue a warning about the disaster.
The trial which starts Tuesday (09/20/2011) was heavily criticized, especially from the scientific community. Their argument, it is very difficult to predict the exact time and intensity of earthquakes.
An earthquake measuring 6.3 on the Richter Scale occurred on April 6, 2009. Besides destroying the city, the quake also killed 309 people.
Prosecutors filed the indictment was the seventh person issued a statement that is not right before the earthquake struck. And they’ve studied hundreds of vibrations that occur earlier.
The seventh person is a member of a panel formed by the local government to assess the risks that will be faced after a small earthquake tremors a few months before the big quake occurred.
In the meetings held six days before the earthquake, the team concluded that weak vibrations that occur probably not a sign of a major earthquake.
The team notes that ‘it is impossible to predict when a big earthquake will happen. “As well as recommending countermeasures do a more assertive, especially in terms of building construction.
The quake occurred at night, when people were asleep in their homes. They did not leave the house because the team statement.
Most of the victims were killed by a falling building that collapsed. While the people who decided to sleep outside the building survived.
The defendant is a respected scientist in Italy. Among Enzo Boschi, who was president of the National Institute Geofisikan and Volcanology, Giulio Selvaggi (Director of the National Earthquake Center) and Claudio Eva (professor at the University of Genoa).
They were tried together Bernardinis De Bernardo, who was then serving as deputy head of the Civil Protection Department.
More than 5,000 scientists sent an open letter to Italian President Giorgio Napolitano. The letter contains a critique of their colleagues facing court.
