"Nasa claimed the risk to public safety from the “dead” satellite – which is orbiting just over 155 miles above the earth with an inclination of 57 degrees – was “extremely small”.
But senior space agency officials admitted they were “concerned” about the risk to billions of people when it starts falling uncontrolled out of orbit at any stage from later this month.
Nasa admitted more than half a tonne of metal from the satellite, which ran out of fuel in 2005, will survive as the majority of it will burn up after entering Earth's atmosphere.
Scientists estimate the debris footprint will be about 500 miles long with a 1-in-3,200 chance a part a satellite part could hit someone.
While Nasa did not know the exact areas it will fall, the projected danger zone has been narrowed to areas between 57 degrees north and 57 degrees south of the Equator.
These areas cover six continents and billions of people and three oceans."
