Spy satellite to fall from orbit
I'm sure by now most readers of this newsgroup have seen the story of
the disabled spy satellite expected to fall from orbit about a month from now. http://news.yahoo.com/s/ap/20080126/...dead_satellite Anybody know which classifed satellite this is? I read some speculation that it was a KH-11 class satellite which would make it quite large. About the size of Hubble... |

Military will try to shoot down spy satellite
Latest news is that the U.S. will try to shoot down the errant
satellite believed to be in the KH-11 class. The pretext is that the spy satellite contains "hydrazine propellant" that could be hazardous to humans, but I wonder? I'm sure the military wouldn't want anyone getting their hands on any debris falling over land... http://www.cnn.com/2008/TECH/space/0...ite/index.html |

Reentry has not yet begun, but sky watchers are already noticing the satellite as it zips over Europe and the United States shining as brightly as a first or second magnitude star. Typical photos are shown on today's edition of http://spaceweather.com. In fact, USA 193 may never reenter--at least not in one piece. Today, the Pentagon announced it will attempt to blast the satellite with a missile before its orbit decays. This would lessen the chances of dangerous satellite debris and fuel reaching the ground while increasing the population of space junk in low-Earth orbit. I doubt if many of the pieces of the satellite will attain sufficient energy from the impact (or explosion-will the missile have a warhead?) to be boosted into a significantly higher orbit. All the resulting little bits will for the most part have a higher surface area to mass ratio than the intact USA 193. The orbits of the pieces should decay at least as fast as the whole thing. Also, if they blast it near perigee even the boosted pieces will be dipping just as far into the atmosphere as the satellite was, so they should come down pretty soon as well. It just doesn't sound like all that bad of an idea to me (especially for the current crew running the show). Shawn |

Shawn Sorry for replying to my own post, but I just realized perigee is likely to be over some part of the world where they really hate us, so maybe not such a great idea blasting things over the Middle East, Russia or China after all.
