NASA's falling atmospheric research satellite now is expected to meet its demise this afternoon or early this evening, but it's still unclear exactly where an estimated 1,200 pounds of surviving debris will land.
The Upper Atmosphere Research Satellite will not be passing over North America during that timeframe.
So no wreckage is expected to land in the U.S., Canada, Mexico or Central America.
The 6.5-on satellite was last reported in a orbit with high and low points of 110 miles and 115 miles, respectively.
Odds of a single person being struck by any of 26 parts expected to survive atmospheric reentry are 1 in 3,200.
Seventy-five percent of Earth is covered by water, so chances are debris will land in an ocean or sea.
