    The UARS satellite will fall on the coast of Chile


    Reports indicate that the device, the size of a bus, will impact the local 19 hours in the South Pacific, against the Andean country. The place and exact time of the collision may be determined minutes before. Video


    The private firm that follows the route of the UARS satellite, Aerospace Corporation, explained more specifically the impact would be along the coast of Chile, around 7 pm on Friday. However, the head of the company explained that determining the exact time and place is something that is not yet able to predict and know that as you get closer to the ground.

    NASA had reported that the risk of damage is "extremely small", but the phenomenon creates a certain nervousness is felt in the region. The space agency took care to explain that found at an altitude of 115 miles, the atmosphere would probably reach about 17 thousand miles per hour, which to some extent simulate the fall of a rock would find enough obstacles to be stopped.

    This satellite is the largest NASA has fallen to earth in an uncontrolled manner from Skylab in 1979.

    The half-ton of scrap has scaring people , but thanks to a company specializing in software development for U.S. national security, Analytical Graphics (AGI), you can follow live the path of the satellite.

    The video released by AGI shows the path that should have when it loses the satellite orbit.

    In addition, only a couple of hours before you can know more accurately the impact site where the remains , so the U.S. space agency will provide updated information through your website and your Twitter account.

    Remember that the satellite of the Upper Atmosphere Research, UARS, for its acronym in English, weighs about 6 tons and was launched into orbit in 1991 by the shuttle Discovery to explore the upper atmosphere and measurements of the ozone layer.

        Update #10

        Fri, 23 Sep 2011 09:45:08 AM CDT


        As of 10:30 a.m. EDT on Sept. 23, 2011, the orbit of UARS was 100 miles by 105 miles (160 km by 170 km). Re-entry is expected late Friday, Sept. 23, or early Saturday, Sept. 24, Eastern Daylight Time. Solar activity is no longer the major factor in the satellite?s rate of descent. The satellite?s orientation or configuration apparently has changed, and that is now slowing its descent. There is a low probability any debris that survives re-entry will land in the United States, but the possibility cannot be discounted because of this changing rate of descent. It is still too early to predict the time and location of re-entry with any certainty, but predictions will become more refined in the next 12 to 18 hours.

          Here's a website for another group monitoring the UARS path. They look credible. (I was interested to see that former astronaut Sally K. Ride is on their Board of Trustees.)

          There is a legend under the path map that explains everything.

            Fri, 23 Sep 2011 06:30:46 PM CDT


            As of 7 p.m. EDT on Sept. 23, 2011, the orbit of UARS was 90 miles by 95 miles (145 km by 150 km). Re-entry is expected between 11 p.m. Friday, Sept. 23, and 3 a.m., Sept. 24, Eastern Daylight Time (3 a.m. to 7 a.m. GMT). During that time period, the satellite will be passing over Canada, Africa and Australia, as well as vast areas of the Pacific, Atlantic and Indian oceans. The risk to public safety is very remote.

                      Earlier, it was reported that the satellite clung to space Friday, apparently flipping position in its ever-lower orbit and stalling its death plunge.

                      "It just doesn't want to come down," said Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics.

                      McDowell said the satellite's delayed demise demonstrates how unreliable predictions can be. That said, "the best guess is that it will still splash in the ocean, just because there's more ocean out there."....

                            UARS Re-Entry Overview
                            • NASA's UARS Re-enters Earth's Atmosphere

                              NASA?s decommissioned Upper Atmosphere Research Satellite (UARS) fell back to Earth between 11:23 p.m. EDT Friday, Sept. 23 and 1:09 a.m. Sept. 24, 20 years and nine days after its launch on a 14-year mission that produced some of the first long-term records of chemicals in the atmosphere.

                              The precise re-entry time and location of debris impacts have not been determined. During the re-entry period, the satellite passed from the east coast of Africa over the Indian Ocean, then the Pacific Ocean, then across northern Canada, then across the northern Atlantic Ocean, to a point over West Africa. The vast majority of the orbital transit was over water, with some flight over northern Canada and West Africa.

                              Six years after the end of its productive scientific life, UARS broke into pieces during re-entry, and most of it up burned in the atmosphere. Data indicates the satellite likely broke apart and landed in the Pacific Ocean far off the U.S. coast. Twenty-six satellite components, weighing a total of about 1,200 pounds, could have survived the fiery re-entry and reach the surface of Earth. However, NASA is not aware of any reports of injury or property damage.

                              The Operations Center for JFCC-Space, the Joint Functional Component Command at Vandenberg Air Force Base, Calif., which works around the clock detecting, identifying and tracking all man-made objects in Earth orbit, tracked the movements of UARS through the satellite?s final orbits and provided confirmation of re-entry.

                              ?We extend our appreciation to the Joint Space Operations Center for monitoring UARS not only this past week but also throughout its entire 20 years on orbit,? said Nick Johnson, NASA?s chief scientist for orbital debris, at NASA?s Johnson Space Center in Houston. ?This was not an easy re-entry to predict because of the natural forces acting on the satellite as its orbit decayed. Space-faring nations around the world also were monitoring the satellite?s descent in the last two hours and all the predictions were well within the range estimated by JSpOC.?

                              UARS was launched Sept. 12, 1991, aboard space shuttle mission STS-48 and deployed on Sept. 15, 1991. It was the first multi-instrumented satellite to observe numerous chemical components of the atmosphere for better understanding of photochemistry. UARS data marked the beginning of many long-term records for key chemicals in the atmosphere. The satellite also provided key data on the amount of light that comes from the sun at ultraviolet and visible wavelengths. UARS ceased its scientific life in 2005.

                              Because of the satellite's orbit, any surviving components of UARS should have landed within a zone between 57 degrees north latitude and 57 degrees south latitude. It is impossible to pinpoint just where in that zone the debris landed, but NASA estimates the debris footprint to be about 500 miles long.

                              NASA?s decommissioned Upper Atmosphere Research Satellite fell back to Earth at 12 a.m. EDT (0400 GMT), as Friday, Sept. 23, turned to Saturday, Sept. 24 on the United States east coast. 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.

                                A six-ton satellite raced along New Zealand's west coast and crossed just north of Auckland in its death dive on Saturday, a Nasa map reveals.

                                It would have been plunging through New Zealand skies at around 5pm on Saturday.

                                Bits of it could have showered down on another part of New Zealand ? Tokelau in the South Pacific.
