In any event, NASA does have a software model to calculate the likely time of death of UARS, and the time equals, in turn, the location of where whatever debris is left of the trolley-sized space-machine hits the planet. And this morning, NASA has put out a new estimate.
UARS will likely re-enter tomorrow, September 23rd, during the afternoon, US Eastern Daylight Time. It will NOT be passing over North America during that time. Remember that the field of debris is expected to be quite long and narrow.
What this means is that you should keep an eye on Twitter. The hashtag is #UARS. The moment you start to see tweets of fireworks or debris, plot it on a map. Two points is all you'll need to predict the downstream end of the debris field.
You should have a pair of gloves and several different size bags ready, as well as some stick-on labels, a Magic Marker, and a notebook and pencil to label the bits and take notes on where you found them.
Good luck, Astro-litter-bugs!
