Before there was 'Sunday Picks' - There was 'The Sky is Falling'

'NASA refines the crash window for the Upper Atmosphere Research Satellite to sometime between "whenever" and "later, possibly Sunday'."

'Odds of a human life being squashed? 1 in 3,200'.

'Odds of right-wing outrage over Obama allowing this to happen? 2 to 5'.

'Nasa refines satellite crash time'
'By Paul Rincon'
'Science editor, BBC News website'
'The US space agency (Nasa) says that its out-of-control climate satellite is expected to crash to Earth sometime on Friday evening (GMT)'.
'There is still much uncertainty over when and where the satellite will re-enter the atmosphere'.
'Satellite and space expert Dr Stuart Eves stressed the large uncertainties involved in tracking the "decay" of satellite orbits (their slow fall back into the Earth's atmosphere)'.
'Using the most recent determination of UARS' orbit - taken in the early hours of this morning - Dr Eves and a colleague have come up with their own projections of the satellite's final descent. But he explained that a spacecraft's orbit lifetime could only be estimated to about 10% accuracy'.
'This translates to a six-hour window either side of the expected decay which is based on a range of probabilities. Calculations using the data available on Thursday afternoon suggested a splash down in the Southern Ocean. But this is likely to change as tracking specialists get a better fix closer to Friday evening'.
'In its latest update, the space agency said only that the spacecraft would "not be passing over North America" when it is expected to be pulled through the atmosphere to Earth'.
'The spacecraft could pass over Britain during its final passes over the planet'.
