[Updated 10:54 p.m. ET] A defunct satellite has entered the atmosphere, the German Aerospace Center reported Sunday morning.
"There is currently no confirmation if pieces of debris have reached Earth's surface," it said. Up to 30 pieces of space debris could hit land or water.
[Posted 4:29 p.m. ET] The earliest possible re-entry of a decommissioned German satellite into the Earth's atmosphere was pushed back to Saturday evening Eastern time, the German space agency's website said.
The agency originally had projected Saturday afternoon as the earliest re-entry for the satellite, which could include up to 30 individual pieces of debris.
As of 4 p.m. ET Saturday, the agency's latest prediction narrowed the re-entry to a six-hour window during Saturday night.
"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 (DLR).
The time and location of the Roentgen Satellite's (ROSAT) re-entry couldn't be forecast precisely, and officials estimated the fiery event to occur any time between 7:30 p.m. ET Saturday and 1:30 a.m. ET Sunday, the agency said.FULL STORY
