Parts of a German satellite will crash to Earth Saturday night, the German Aerospace Center said.
Germany's X-ray telescope ROSAT is currently 105 miles above Earth's surface, RIA Novosti reported.
As many as 30 pieces weighing as much as 1.6 tons are expected to hit along a 50-mile-wide path between Berlin and Samara, Russia.
The pieces will be hitting Earth between 10 p.m. Saturday and 4 p.m. Sunday.
The X-ray satellite's mirrors, optics and instruments have heavy protection from overheating and will not burn up when entering the atmosphere, the report said.
There is a 1-in-2,000 chance of someone on the ground being injured by the satellite's debris.
ROSAT was put into orbit in 1990 and weighs a total of 2.4 tons.
