UARS - Re-entry imminent
NASA's Upper Atmosphere Research Satellite, or UARS, is expected to re-enter Earth's atmosphere in late September or early October 2011, almost six years after the end of a productive scientific life. Although the spacecraft will break into pieces during re-entry, not all of it will burn up in the atmosphere.
The risk to public safety or property is extremely small, and safety is NASA's top priority. Since the beginning of the Space Age in the late-1950s, there have been no confirmed reports of an injury resulting from re-entering space objects. Nor is there a record of significant property damage resulting from a satellite re-entry.

Update: As of Sept. 20, 2011, the orbit of UARS was 127 mi by 140 mi (205 km by 225 km). Re-entry is expected Sept. 23, plus or minus a day. It is still too early to predict the time and location of re-entry. Predictions will become more refined over the next two days.
Space Weather News for Sept. 20, 2011

UARS, a NASA satellite the size of a small bus, will re-enter Earth's atmosphere later this week producing a brilliant fireball somewhere over our planet. Best estimates place the re-entry time during the late hours of Sept. 23rd over a still-unknown region of Earth. Observers of the rapidly-decaying satellite say it is tumbling and flashing, sometimes almost as brightly as Venus. Video images featured on today's edition of http://spaceweather.com (http://spaceweather.com) show how the doomed satellite looks through a backyard telescope.

Nasa's UARS satellite falls off west coast of US
Nasa says its six-tonne UARS satellite plunged to Earth over the Pacific Ocean, off the US west coast.
It appears likely the decommissioned craft came down between 03:23 and 05:09 GMT - with a best estimate of 04:16.
If correct, this means any debris that survived to the surface probably went into water and not on land.
