Scientists said on Thursday they won’t know until about two hours before a defunct NASA satellite re-enters the earth’s atmosphere, where it will likely land.
The six-tonne research satellite, which is the size of a bus, is expected to break-up before it lands on earth on Friday.
The 20-year-old satellite is most likely to fall into the ocean or onto desert areas. NASA said the odds that a person will be hit by a piece of debris are about 1 in 3,200.
