Nicholas Johnson, NASA's chief orbital debris scientist, says their analysis shows that 26 parts of UARS will survive. "These 26 components, which we anticipate will survive all the way down, will be going at a moderate velocity of tens to hundreds of miles an hour," he said. "All these 26 have been identified as potentially causing damage if they hit a structure or a person but the odds of that are very, very, low."
Johnson said any one person's chances of getting hit by debris are tiny -- something like 1 in 21 trillion. The chances that of the 7 billion people on Earth, one of them, somewhere, could be hit -- those odds are more like 1 in 3,200.
