Hydrazine doesn't seem like it would present too large of a problem if it burned in the upper atmosphere. Does anyone know just how much hydrazine is involved? Half a ton. Probably frozen solid, but without telemetry, there's no way to tell. Is the hazard more from a tank full of the stuff making it to the surface intact? I'd suspect the problem is if it makes it intact. The Wikipedia article refers to its use in the Me-163 Komet of WWII. The plane occasionally *dissolved* pilots during accidents.... Ron Wanttaja |

CREATED: 18 FEB 12:51 2008 Ah, communication. Who *writes* these things? I can't even tell you what state(s) this thing is talking about, without donning my pilots decoder ring. You shouldn't have to study it very long to realize the area described is in the Pacific Ocean and the only US state in the general vicinity is Hawaii. I still remember flying in the desert Southwest, far from home, and having a briefer read a forest fire NOTAM to me in this sort of language, over the radio. No reference to landmarks. No reference to cities. Just LAT/LON. Useless. It's not useless if you carry charts. Almost as bad are the ones that say "13 miles from the Blather VOR, on the 178 radial" -- leaving you to figure out where in hell the Blather VOR is... Good luck finding it on your sectional chart, in flight, in the dark. Why would you have to find Blather VOR at all? If you know where you are and you can't find Blather VOR anyehere near your position or route you know the NOTAM doesn't affect you. Is there some reason these things can't use commonly known landmarks (cities, national parks, rivers, etc.) to communicate their message? That would make locating them more difficult. |

As you point out it will be a heck of an accomplishment - which means it is hard, not easy... I feel they have been spooked by the Chinese, so they feel they have to 'catch up'... Same reponse to Sputnik in 57.. And if so, the odds are the early going will be the same results.. PBS just had a NOVA documentary on Sputnik and the US side of the story. We had a Redstone rocket ready to go BEFORE Sputnik but egos got in the way and the Russians beat us to it. It was a really good program though. |

Mmm... Would that be a yawn at the thought of McCain's hawkish stand
and Bush endorsement (more of the same), a cringe at Huckabee's Christian supremist agenda in persecution the Crusades, and a laugh at Clinton's desperate reliance on feminine emotional displays to soften here image in the public eye? I wasn't even considering Huckabee. -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

Wil http://www.msnbc.msn.com/id/23265613/ Navy missile hits spy satellite Extraordinary operation requires steady seas and optimum positioning WASHINGTON - A missile launched from a Navy ship successfully struck a dying U.S. spy satellite passing 130 miles over the Pacific on Wednesday, a defense official said. Two officials said the missile was launched successfully just after 10:30 p.m. ET. One official, who is close to the process, said it hit the target. He said details on the results were not immediately known. The goal in this first-of-its-kind mission for the Navy was not just to hit the satellite but to obliterate a tank aboard the spacecraft carrying 1,000 pounds of a toxic fuel called hydrazine. U.S. officials have said the fuel would pose a potential health hazard to humans if it landed in a populated area. Although the odds of that were small even if the Pentagon had chosen not to try to shoot down the satellite, it was determined that it was worth trying to eliminate even that small chance. Officials said it might take a day or longer to know for sure if the toxic fuel was blown up. The government has organized hazardous materials teams to be flown to the site of any dangerous or otherwise sensitive debris that might land in the U.S. or elsewhere. The operation was so extraordinary, with such intense international publicity and political ramifications, that Defense Secretary Robert Gates -- not a military commander -- made the final decision to pull the trigger. The U.S. government organized hazardous materials teams, under the code name "Burnt Frost," to be flown to the site of any dangerous or otherwise sensitive debris that might land in the United States or elsewhere. High seas in the north Pacific had threatened to postpone the launch as the USS Lake Erie prepared a three-stage missile. Beyond a certain point, rough seas can interfere with the cruiser's launch procedures. The NAvy launched a SM-3 missile 130 miles to just beyond the edge of the Earth's atmosphere in an attempt to speed its non-explosive warhead directly into the satellite. Early in the day, a senior military officer said it did not look as if the weather would be good enough. That was shortly after the space shuttle Atlantis landed, removing the last safety issue for the military to begin determining the best moment for launch. The aim was not just to hit the bus-sized satellite -- which would burn up upon re-entering the atmosphere anyway -- but to obliterate a tank onboard that is carrying 1,000 pounds of hydrazine, a toxic fuel. The fuel, unused because the satellite died shortly after reaching orbit in December 2006 -- could be hazardous if it landed in a populated area. The Centers for Disease Control and Prevention issued a health bulletin saying that the health risk from satellite debris was considered to be low. "However, CDC is encouraging health officials and clinicians to review information about the health effects related to hydrazine to prepare in case their communities are affected by satellite debris." In a routine precaution, notifications have been issued worldwide to mariners and aviators to stay clear of an area in the Pacific where the satellite debris might fall. The military has calculated that the risk to aviation is so low that U.S. and international aviation officials decided not to reroute air traffic, a senior military officer said Wednesday. The shootdown, which was approved by President George W. Bush, is seen by some as blurring the lines between defending against a hostile long- range missile and targeting satellites in orbit. Much of the equipment used in the satellite shootdown was part of the Pentagon's missile defense system, a far-flung network of interceptors, radars and communications systems designed primarily to hit an incoming hostile ballistic missile fired at the United States by North Korea. The equipment, including the Navy missile, has never been used against a satellite or other such target. The three-stage Navy missile has chalked up a high rate of success in tests since 2002 -- in each case targeting a short- or medium-range missile. A hurry-up program to adapt the missile for this anti- satellite mission was completed in a matter of weeks; Navy officials say the changes will be reversed once this satellite is down. Left alone, the satellite would have been expected to hit Earth during the first week of March. About half of the 5,000-pound spacecraft would be expected to survive its blazing descent through the atmosphere and would scatter debris over several hundred miles. |
