The 6-ton UARS satellite — the biggest piece of space debris to fall from the sky since Sky Lab in 1979 — fell back to Earth early Saturday morning. Debris is reported to have been found near Calgary, Canada.The wait is over. NASA's bus-sized Upper Atmosphere Research Satellite (UARS) has fallen, becoming the largest runaway chunk of space junk to drop back down to Earth since two satellites, including the behemoth Sky Lab, punched the atmosphere in 1979. "We can now confirm that #UARS is down!" reported the official NASA Twitter account. "Debris fell to Earth between 11:23 p.m. EDT...

Well FRiends...the UARS, according to NASA this morning, is now supposed to come down between 0000 and 0400 UTC, or between 5pm and 9pm Pacific time. According to 'Orbitron', during that time frame UARS will cross the US three times, once over the Eastern Seaboard (Entering near the Louisiana/Mississippi border, up over the Appalachians, and exiting along the US/Canada border near upstate New York) , once across the Midwest (on a line from AZ/NM border up to the ND/MN border), and finally crossing the Pacific Northwest (entering off the Oregon coast, crossing between Portland and Seattle, and exiting the US...

A NASA satellite the size of a school bus is just days away from taking a fiery plunge into Earth’s atmosphere and could set off a dazzling display when it does … if anyone is able to see it. NASA's 6 ½-ton Upper Atmosphere Research Satellite is due to fall somewhere on Earth Friday (Sept. 23), though exactly where and when remains a mystery. If you happened to be lucky enough to be within viewing range of a satellite that is re-entering the atmosphere, the sight, put simply, would amount to a short-lived but spectacular fireworks display. Unlike a fireball...

A dead climate satellite that has been circling Earth for 20 years will make a fiery death plunge this week, with some pieces of the 6 1/2 ton spacecraft expected to reach the surface of the planet, NASA officials say. The bus-size Upper Atmosphere Research Satellite, or UARS, will likely plummet down to Earth sometime around Friday (Sept. 23), according to NASA's latest projections. There is a 1-in-3,200 chance that UARS debris could hit a person, though NASA considers that scenario extremely remote. "Re-entry is expected Sept. 23, plus or minus a day," NASA officials wrote in an update posted...

(Reuters) - A defunct NASA science satellite is expected to fall back to Earth on Friday, showering debris somewhere on the planet although scientists cannot predict exactly where, officials said. The 6.5-ton Upper Atmosphere Research Satellite, or UARS, was carried into orbit during a space shuttle mission in 1991. It operated for 14 years,collecting measurements of ozone and other chemicals in the atmosphere. Since completing its mission in 2005, UARS has been slowly losing altitude, tugged by Earth's gravity. On Friday, the 35-foot-long, 15-foot diameter (10.6-metres long, 4.5-metres diameter) satellite is expected to plunge into the atmosphere, NASA reported on...
