Anonymous Coward User ID: 24473625 Spain 09/26/2012 05:30 PM Report Abusive Post Report Copyright Violation | ... Quoting: Anonymous Coward 24406931 LOL, yeah, better wording than mine. BTW, do the alloys that the satellites are made of, can be affected (pulled) by a magnetic body? I suppose, but it's not going to be detectably affected by a "magnetic asteroid" if that's what you're thinking. Such a force would decrease with the inverse cube of the distance, not the inverse square as with gravity. The relative velocity between any of these satellites and the asteroid is also so high that it makes either the gravity or magnetism of the asteroid irrelevant. Please, Would you mind to explain this? [link to www.gsjournal.net] Here's an elementary level demonstration of the concept: [link to image.gsfc.nasa.gov] You'll first need to build one of these: [link to image.gsfc.nasa.gov] Thanks a lot! |

SilentlyKnowing User ID: 27028191 United States 02/07/2013 08:37 PM Report Abusive Post Report Copyright Violation | there are a lot of problems in that orbit. normally there is only supposed to be a satellite every 2deg or so, but lately they have been double and triple stacking them. most of the "stacks" will be of different bands, such as c-band Ka, Ku, EHF, X (and whatnot). Quoting: Tic-Toc- What is worrying me is they started to stack the linear wave length satellites. Normally there is supposed to be a 30db isolation between polarities. However with like-satellites being only .5 degrees apart and a polarity difference of 45 degrees, the max you could effectively get is about 20 db of isolation between all polarities and satellites. What this does is increase the required powers of the carriers and subsequently increases the noise floor of the satellite. This will result in a lowering of available bandwidth by the required increases of guard-bands. We need to get rid of some of these older satellites out of the orbit because their flight patterns are taking up to almost 3 degrees. I mean, sure traffic can still be passed, but the doppler effect is starting to cause an extreme amount of errors. Wow! Tic-Toc! You really know your stuff about these satellites! You don't offer an opinion, though, as to whether Dr. Astro here is right-on about our not having to worry about a satellite collision with 2012-AD14. Do you have one? I don't know how ANYONE can give a credible account for EVERY piece of space junk out there to be 100% certain that the 2012-AD fly-by will be uneventful. I don't buy it! Glad to see you up on the board Dr. Astro! (Be nice...I have already been abused! lol!) Cheers! SK |

I don't buy it! If it hits a piece of space debris at this point, no one will really have to worry about it; it's not going through the clarke belt, so the debris generation would be well below our geostationary satellites. |

If the 2012DA14 did collide with a sat. Could the impact affect the ateroids trajectory? Or are the sats. to small to do that? Quoting: Ozi dude 33907544 By the it's close enough to hit a satellite it's already too late to change the trajectory in a manner that would result in an earth impact on that orbit. |

No, there is not some grand conspiracy, I'm not a mod so I had no power over when it was unpinned. I also went to bed after I made my last comment. Perhaps you were impatient because you fretted over my response. Well as I stated within the video and within the comments when I posted the video, I was specifically showing geostationary and geosynchronous satellites since those are the ones that are most vulnerable and most susceptible to a domino effect of collisions. Satellites below geostationary and above low earth orbit are much more sparse and mostly involve Molniya-type orbits. But yes I have the data on that as well, and yes, I mean ALL satellites including those you think only "an insider" would have. Real amateur astronomers are very good at finding things in space that the government doesn't want you to know about, including classified satellites: [link to www.prismnet.com] I'll make a special video just for GLP and show that data as well. Please don't report it to DHS... |

Please don't report it to DHS... Thankyou for your response. I am on this site because I am skeptical, so therefore am skeptical your intentions. This is a reasonable, fair response to my concerns. You have stated a couple of years ago that you are a believer of the Bible. You are obviously very smart and passionate about Astronomy, so I would like a response about how the theories on this board could play out in the Biblical sense. I'm sure you can see that the Bible is a coded book, warning of Astronomical events that are yet unknown and incredible. Considering your passion I would like to know your thoughts on possible Astronomical, Biblical end time events. |
Anonymous Coward User ID: 32728816 United States 02/08/2013 04:22 PM Report Abusive Post Report Copyright Violation | At the suggestion of GLP member SE last week, I decided to do another analysis of 2012 DA14's close approach to earth in February, this time looking for potential collisions with geosynchronous satellites. Although the uncertainty region shows that a collision with earth is not a possibility, a collision with a satellite cannot be completely ruled out. National Geographic even published an article about this on their website back in May, but they never spelled out which satellites are most at risk (though again, "most" in this case is still extremely low). Quoting: Dr. Astro [link to news.nationalgeographic.com] Here's my analysis, showing which satellites are at risk: should i bring in my tomato plant? |
