UARS Journey Comes To An End 23SEP2011

NASA's Upper Atmosphere Research Satellite, or UARS, Likely No More

Update #15Sat, 24 Sep 2011 01:46:42 AM MDT
NASA’s decommissioned Upper Atmosphere Research Satellite fell back to Earth between 11:23 p.m. EDT Friday, Sept. 23 and 1:09 a.m. EDT Sept. 24. The Joint Space Operations Center at Vandenberg Air Force Base in California said the satellite penetrated the atmosphere over the Pacific Ocean. The precise re-entry time and location are not yet known with certainty.

LAST SIGHTINGS OF UARS? Observers in central Texas saw UARS streaking overhead (but not disintegrating) at 8:18 PM CDT on Sept. 23rd. It was spotted again over western Colorado at ~9:46 pm CDT ("Still intact, but tumbling," says observer Scott Sheriff) and again over Minnesota at 9:55 pm CDT. Since then, however, no observers have reported seeing the doomed satellite. NASA's estimated window for re-entry (between 11:45 p.m. Sept. 23 and 12:45 a.m. Sept. 24 EDT) has passed, so UARS might be no more.
