Poor Canada, first the Soviet satellite with the reactor on it, now this:

Pat looks like no one was hurt...... it went down in a sparsley setteled area. probably the worst would of been debris hitting a major metropoltian area anywhere in the world....... as a single hit item a debris hit to a nuke power plant or waste core storage pool could of created another fukashima |

I think the breakup may have been a more drawn out process than NASA expected. I saw a meteor moving in the correct direction and in the general part of the sky I was searching for UARS from San Angelo, Texas around 8:20 Central, but no sign of the satellite. At first I thought it was just a natural meteor, but the more I think about it, that's a pretty damned big coincidence. But that's at least one orbit, maybe two, before NASA says UARS came down. probably the worst would of been debris hitting a major metropoltian area anywhere in the world....... Even then the odds are great it would have just landed on someone's roof or in a street. Lots of amazed gawkers standing around taking pictures of it with the cellphones. as a single hit item a debris hit to a nuke power plant or waste core storage pool could of created another fukashima Not really. Remember, it isn't going 17,000mph when it hits the ground, it's at terminal velocity. Hitting a building isn't any worse than hitting the ground, and there is lots of space junk (Delta II parts, Columbia wreckage, tanks from SkyLab) that is still more or less recognizable after slamming into the ground. A space debris hit is not going to cause a power plant to go China Syndrome. Brian |

Pat Space Junk/Debris (mostly of the lethal kind if encountered at any closing velocity) There’s supposedly 1100+ working satellites (plus x-number of secret ones) and perhaps twice that many dysfunctional or dead, not to mention those already in bits because of collisions and/or being intentionally shot at. Actually the official number of dead satellites can’t be told, nor the true all-inclusive cost of our having to track everything of 10+ cm (22,000 items and growing). The danger of space debris / by Micah Zenko http://globalpublicsquare.blogs.cnn....-space-debris/ “Presently, there are some 22,000 items over ten centimeters across, or roughly the size of a softball, which can be regularly tracked with existing resources and technology. These include the upper stages of launch vehicles, disabled spacecraft, dead batteries, solid rocket motor waste, and refuse from human missions. In addition, there are approximately 300,000 other fragments of space junk measuring between one and ten centimeters, and over 135,000,000 less than one centimeter, which could potentially damage operational spacecraft.” http://translate.google.com/# Brad Guth, Brad_Guth, Brad.Guth, BradGuth, BG / “Guth Usenet” |

It turns out the Okotoks report was an error or a hoax, and the debris
came down in the South Pacific, from later news reports (not to be confused with where it hit the atmosphere, which was also over the South Pacific). John Savard |

Don't be silly. *LEO is mostly 'self-clearing'. *Orbits decay and the stuff comes down. Once again, Bobbert will explain to us how the sky is falling.... -- "Ordinarily he is insane. But he has lucid moments when he is *only stupid." * * * * * * * * * * * * * * -- Heinrich Heine self cleaning it is BUT at theres a tipping point where debris can be generated faster than orbital decay creating a cloud of junk that will endanger not only satellites but things like ISS, and more importandly endanger new launches all of which must pass thru LEO.... one LEO earth orbit test or a satellite explosion for any reason is a real hazard. since according to a shuttle FDO the debris will spread somewhat evenly. years ago a paint speck off a russian vehicle nearly put a hole in a shuttle windshield. imagine a soyuz capsule being taken out by a piece of debris too small to track.......... |
