The spacecraft will be 300 miles to the northeast, southwest of Christmas Island, have sunk away from any landmass, NASA said.
"This is a relatively uninhabited world, far away," said NASA scientist Mark Matney space debris for the Associated Press. "This is definitely a good place in terms of risk."
The research satellites disintegrated in the upper atmosphere during re-entry and most burned in the atmosphere, the agency said. Satellite Components 26 years old with a weight of 1200 pounds might have survived the fall.
"It was not easy re-entry to predict because the natural forces that is forfeited to the satellites into orbit," said Nick Johnson, chief scientist for space debris at NASA's Johnson Space Center in Houston. "Space-faring nations have been pursuing the world's satellites."
On Saturday, NASA said it was possible that debris could have fallen in the north-western Canada, and there were reports of people ask for comments on the Internet. But UARS landed earlier than expected, to completely change the wreckage landed.
As NASA has been following the satellite trajectory slow down, the agency has claimed that the threat was to public safety and property are extremely low.
The satellite was launched 20 years 12th September 1991 and in operation three days later. Was put into orbit to collect measurements of ozone and other chemicals in the atmosphere. The mission ended in 2005. Since the spacecraft, which measures 35 meters long and 15 meters in diameter begin to lose altitude to how it was collected by gravity.
The last time a ship as big as the earth fell on UARS is controlled when Skylab fell in Western Australia in 1979.
