Satellite allemand en route vers la terre..
Le risque d'être frappé par une pièce serait très faible...
"Europe, Africa and Australia appeared to be out of the path of a defunct German satellite that neared the Earth's atmosphere, bringing with it the possibility of 30 pieces of space junk landing somewhere.
"The largest single fragment will probably be the telescope's mirror, which is very heat resistant and may weigh up to 1.7 tons," according to the German Aerospace Center.
The time and location of the Roentgen Satellite's re-entry couldn't be forecast precisely. Officials estimated the fiery event to occur any time before 11:30 p.m. ET Saturday, the agency said, with two orbits.
"The likelihood of a person getting injured as a result of the re-entry is extremely low," the agency said.
Tariq Malik, managing editor of space.com, told CNN Saturday night that "there is no serious contamination threat" from the satellite.
Fragments could fall to Earth in about a 50-mile-wide (80-kilometer-wide) path as the satellite enters the atmosphere at 17,398 mpg (28,000 kph) and breaks up under extreme heat, the agency said."
