    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...

    A huge, dead satellite tumbling to Earth is falling slower than expected, and may now plummet down somewhere over the United States tonight or early Saturday, despite forecasts that it would miss North America entirely, NASA officials now say. The 6 1/2-ton Upper Atmosphere Research Satellite (UARS) was expected to fall to Earth sometime this afternoon (Sept. 23), but changes in the school bus-size satellite's motion may push it to early Saturday, according to NASA's latest observations of the spacecraft. "The satellite's orientation or configuration apparently has changed, and that is now slowing its descent," NASA officials wrote in a...

    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...
  • Nasa refines satellite crash time ('out-of-control' climate satellite crash Pool anyone?)

    The US space agency (Nasa) says that its out-of-control climate satellite is expected to crash to Earth sometime on Friday evening (GMT). There is still much uncertainty over when and where the satellite will re-enter the atmosphere. Experts say they will get a more precise idea in the last 12 hours before the satellite is due to return. The US space agency says the risk to life from the Upper Atmosphere Research Satellite (UARS) is 1 in 3,200. Satellite and space expert Dr Stuart Eves stressed the large uncertainties involved in tracking the "decay" of satellite orbits (their slow fall...
  • Falling NASA Satellite Could Spark Stunning Light Show

    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...

    (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...
