The US space agency has narrowed down its prediction of when a defunct 
six-tonne satellite will crash back to Earth, saying it is expected to land on 
September 23 US time (tomorrow Melbourne time).

All but 26 pieces of the Upper Atmosphere Research Satellite (UARS) are 
expected to burn up on re-entry into the atmosphere, but where they will land 
remains a mystery.

Scientists say the pieces will fall somewhere between 57 north latitude and 57 
south latitude, which covers most of the populated world.

The debris footprint is expected to span 800 kilometres.

UARS is the biggest NASA spacecraft to come back in three decades, after Skylab 
fell in Western Australia in 1979.
