NASA's Upper Atmosphere Research Satellite, or UARS, is expected to re-enter Earth's atmosphere late SeptemberHave you heard the news that today, September 23, 2011 is the day the NASA’s Upper Atmosphere Research Satellite, UARS  plunges to earth somewhere?

This story will be updated all day today to keep people informed as to the best estimation of where it will land.

Here is a video demonstration of what has occurred and what we can expect as the satellite reaches earth today.

The 6.3 ton UARS launched from the shuttle Discovery in 1991 and decommissioned it in 2005. A NASA analysis using software designed to evaluate satellite decays indicates 26 chunks of debris, the largest weighing 330 pounds or so, likely will survive atmospheric friction to hit the ground somewhere along a 500- ile track downrange of the entry point.  Source Patience, lots of luck need to spot falling sattelite, September 21, 2011.

It is one of those rare events that will receive a lot of attention today.  Most of the predictions I read have the satellite touching earth in the late afternoon, 4.00 – 6.00pm U.S. Central Time.

I am sure by tonight, we will see pictures/articles and  lots of posts and tweets on social media sites regarding this event.
