A dead NASA satellite, called the Upper Atmosphere Research Satellite (UARS), is falling uncontrolled toward Earth and crash in the Pacific Ocean on Saturday, Sept. 24. Agency officials are unable to pinpoint the exact time and location of the fall, but have said there is little risk of debris landing in populated areas. SPACE.com is providing full coverage of the UARS re-entry, including a look at the issues surrounding orbital debris and space situational awareness.
FINAL NASA Update (Sept. 27 PM):
"NASA's decommissioned Upper Atmosphere Research Satellite fell back to Earth at 12:01 a.m. EDT (0401 GMT) on Saturday, Sept. 24. The Joint Space Operations Center at Vandenberg Air Force Base in California has determined the satellite entered the atmosphere over the Pacific Ocean at 14.1 degrees south latitude and 189.8 degrees east longitude (170.2 west longitude). This location is over a broad, remote ocean area in the Southern Hemisphere, far from any major land mass. The debris field is located between 300 miles and 800 miles downrange, or generally northeast of the re-entry point. NASA is not aware of any possible debris sightings from this geographic area.
This is your source for official information on the re-entry of UARS. All information posted here has been verified with a government or law enforcement agency. This is NASA's final status report on the re-entry of UARS."
