Fragments from an old 6-ton NASA satellite hurtled toward Earth on Friday, while the exact site of the crash-landing remained a mystery into the final hours.
The US space agency has stressed that the risk is "extremely small" that any of the 26 chunks that are expected to survive the fiery re-entry into Earth's atmosphere will hit one of the planet's seven billion people a one in 3,200 chance.
"Re-entry is possible sometime during the afternoon or early evening of Sept 23, Eastern Daylight Time," NASA said on its website on Thursday night.
That would be early morning Saturday Beijing time.
It was reported that someone found the ‘possible“ fragments falling down in a small town of Calgary, Alberta, Canada.
How do you think the space rubbish is safe or not for earth?
