IOW, the satellite struck Obama's birthplace.
I don't buy this BS.
NASA knows precisely the area and the time the satellite splashed down.
Actually, that would be impossible, since it broke up into many pieces as it came down, with some parts falling at different rates than others, hitting the earth at different times, and leaving a large debris field. But I think I know what you mean :)
Thank goodness we weren’t trying to track a MIRV.

NASAs decommissioned Upper Atmosphere Research Satellite fell back to Earth between 11:23 p.m. EDT Friday, Sept. 23 and 1:09 a.m. EDT Sept. 24. The Joint Space Operations Center at Vandenberg Air Force Base in California said the satellite penetrated the atmosphere over the Pacific Ocean. The precise re-entry time and location are not yet known with certainty.
So, I guess it landed in the water
The insurance adjustor came out to the farm and told my Dad he couldn't give him full coverage because part of the barn was still standing. My Dad told the adjustor to follow him as he had something to show him. They walked deep into the part of the barn still standing. As they stood there with it creaking in the wind, my dad said "I don't feel safe in here." Full coverage was provided.
Owww! That hurt!
That was salt-of-the-earth genius - making his point and getting to the core of the matter in 6 words. Results like that would normally take a team of lawyers and months of negotiations!
It might hit Washington, DC, which might not be a bad thing, depending on where.
Where did it land in the Pacific I heard?
The answer may be obvious,but how are they(NASA)bringing it down? I’m just wondering how a satellite can be brought back down to earth.
We (the US) have used anti-satellite missiles to bring both test vehicles and (at least) one NASA satellite. The NASA satellite was going to crash - and so they brought it down into the ocean.
I read that this one has been slowly falling to the earth.I understand now how satellites fall out of orbit. It’s very fascinating to me.
Still working in San Diego. Not sure when I can cobble up another opportunity to make a visit home to Idaho. Heavens Above is a fun site for plotting a view of an Iridium flare. They are frequent and easy to spot. An accurate watch helps mark the time when the pass occurs.
NASA Pinpoints Pacific Ocean Grave of Fallen UARS Satellite
NASA and the military have pinned down exactly where and when a huge dead climate satellite fell to Earth on Saturday (Sept. 24).
The defunct Upper Atmospheric Research Satellite (UARS) re-entered the atmosphere at 12:01 a.m. EDT (0401 GMT) on Saturday, falling into the Pacific at 14.1 degrees south latitude and 189.8 degrees east longitude (170.2 west longitude), according to the Joint Space Operations Center at Vandenberg Air Force Base in California. NASA announced the new details today (Sept. 27).
These details close the case on NASA’s 6 1/2-ton UARS satellite, which was launched on a space shuttle in 1991 to study Earth’s ozone layer. The satellite was decommissioned in 2005, and has been slowly losing altitude since.
“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,” NASA wrote in a final status update. “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.”
UARS’ final entry point places it in a “broad, remote ocean area in the Southern Hemisphere, far from any major land mass,” according to the NASA statement.
UARS debris could have scattered 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,” officials wrote.
Just after the UARS spacecraft’s plunge into the Pacific, NASA officials said it was likely the satellite was at the bottom of the ocean, but the exact location and time of its re-entry might never be known. But today, NASA announced that it had identified the satellite’s re-entry point.
NASA originally announced that UARS would fall back to Earth in an “uncontrolled re-entry” in late September or early October, and later refined the prediction down to the day. But no one could predict ahead of time exactly where or when the spacecraft would fall, because its trajectory depended on radiation from the sun and other varying conditions.
Even after the satellite came down, NASA could merely confirm that it had re-entered, most likely within 20 minutes of 12:16 a.m. EDT (0416 GMT), and probably over the Pacific Ocean. “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,” Nick Johnson, NASA’s chief scientist for orbital debris, at NASA’s Johnson Space Center in Houston, said in a statement. “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 satellites descent in the last two hours and all the predictions were well within the range estimated by JSpOC.”
But other satellites will continue to fall. Late in October, or early in November, a German astronomy satellite is set to plunge uncontrolled back to Earth. While slightly smaller than UARS, the German satellite is expected to have more pieces survive re-entry, said McDowell, who worked on one of the instruments for it.
The German ROSAT satellite was launched in 1990, died in 1998, and weighs 2 1/2 tons. The German space agency figures 30 pieces weighing less than 2 tons will survive re-entry. Debris may include sharp mirror shards.
The German space agency puts the odds of somebody somewhere on Earth being hurt by its satellite at 1-in-2,000 — a slightly higher level of risk than was calculated for the NASA satellite. But any one individual’s odds of being struck are 1-in-14 trillion, given there are 7 billion people on the planet.
