Korean satellite misses orbit
Third time unlucky as payload plunges into the Pacific.
It was meant to broadcast a booming anthem to leader Kim Jong-il, but if it did it was heard only by sea nymphs ringing its knell. On 5 April, North Korea's third attempt at a satellite launch, like its predecessors, dropped its payload into the Pacific Ocean.

Replace TM-185 (20-80 gasoline-kerosene) with JP-10 (exo-tetrahydrodicyclopentadiene; endo-isomer is a solid). Nitric acid? More likely AK-27I, inhibited 27% N2O4 + 73% HNO3. This is 1950s missile technology. Somebody north of the 38th parallel should google "turbopump", http://www.snecma.com/snecline/fichiers/Image/05_0039_200401028_002.jpg Hey Korea! Go triethylborane(Et3Al stabilizer)/tetrafluorohydrazine. There is no possible outcome that is not internationally exciting.
yet ,no matter how many times fails we have .if we dare to receipt it and glean from it , so the trimputy is soon
I don't think a certain island nation will be very happy with the news of this 'failure'. Who lies between the first stage sea-fall and the rest that landed in the Pacific Ocean?
It's very interesting how the "failure pattern" goes between Japan. Surely they have something to say against N. Korea.
this was a hidden test of the missile as a carrier for a nuclear weapon, it was not achieved to reach the orbit.
Whether one believes it or not, North Korea?s launching of TaepoDong-2 that flew over Japan into the Pacific Ocean was in fact purely a political demonstration at the extreme than anything else. The autocratic regime did not mean to put a satellite in orbit as claimed; instead it tries to forewarn perceived enemies of its capability to fire long range missiles, with nuclear war-head or not. That was a desperate act of the ailing despot, reminding his direly poor people that he would continue to have the full control over the nation. Unfortunately, this causes great concern on the national security of the neighbours. They would certainly not take the despicable act lightly. In short, the unwelcome launching constitutes a back-stabbing to the global peace, especially to East Asia. (Tan Boon Tee)
I am confused. Did North Korean finally send the satellite into the orbit or not? I was watching CCTV-4 yesterday and saw a celebration rally in the North Korean capital with over 100,000 people for the "succeful" launch.
