CNET, among many other sources, reports that the declining orbit of the Upper Atmosphere Research Satellite has declined all the way; the satellite reentered and broke up in Earth's atmosphere last night, though the exact time, and thus location, of the reentry was unknown at the time. CNET quotes NASA's release, which says the satellite "fell back to Earth between 11:23 p.m. EDT Friday, Sept. 23, and 1:09 a.m. EDT Sept. 24." The Christian Science Monitor has a newer story, which reports that at least some debris from the satellite hit land in Okotoks, Canada, with no injuries. NASA's Science Office page on the satellite (not yet updated to account for the deorbit) says the satellite was launched in 1991, with a planned operational life of three years.
