South Korea's First Rocket Fails To Reach Set Orbit
Matt_dk writes "The first satellite launched by South Korea failed to reach its designated orbit pattern on Tuesday, the NY Times is reporting. The two-staged KSLV-1 rocket, built in cooperation with Russia, failed to deliver the 100-kilogram oceanic and atmospheric research satellite into its target orbit. The rocket was launched from the Naro Space Center, 300 miles south of the capital Seoul. 'The failure to push the satellite into its intended orbit was announced by Ahn Myong-man, the minister of education, science and technology, at a news conference. Mr. Ahn gave no further details. But South Korean news outlets, citing unidentified sources, said the satellite broke away from the rocket about 22 miles farther from the Earth than had been intended.'"
In Soviet Russia... ahh... I don't have anything. I best leave it to the professionals.
"Most people, I think, don't even know what a rootkit is, so why should they care about it?"
âoeNorth Korea will surely try to use the South Korean launch to justify its own,â said Jeung Young-tae, an analyst at the government-financed Korea Institute for National Unification. âoeBut in the end, its attempt will be dismissed as propaganda because there are clear differences between the two.â
Dismissed by who? The rest of world who already knows everything he says is loaded bull.
Or the "citizens" of North Korea who are brainwashed into believing (or supporting) every word he says.
The people of North Korea are so isolated he could say the Japanese were sending over Godzilla to justify an attack, and the outcome would be the same with regards to domestic support.
it went far enough to remind N.Korea that S.Korea has rockets.

I'm not a grammar nazi, but please. Misspelling the very first word in the summary? I could see if it was some complex word, but its THE, what next, is someone going to misspell A ?
the the New York Times? It shouldn't be too hard for the mods to do a basic proofread of the summary before posting. Not that correcting the mistakes changes the content, but because correcting the mistakes doesn't change the content.
Don't know something? Look it up. Still don't know? Then ask.
WTF? Naro and Seoul are damn near the two widest flung points in the R.o.K. This is a bit like describing NASA's Houston control facility as "1200 miles South West of Washington D.C." It's correct, but not particularly useful.

Ostensibly a failure for the South Koreans, since some kind of failure of staging caused the satellite to be inserted into the incorrect orbit. And in all likelihood, the perigee ended up being too low, causing the payload to be inserted into the ocean...
The first stage is basically Russian hardware (Khrunichev), and is basically a flight test of the Angara common booster core with an advanced Russian LOX-kerosene RD-191 engine. Since the failure occurred *AFTER* staging, the failure most likely occurred in South Korean hardware.
So if I were the South Koreans, I'd be fairly pissed right now. Although this is only a first attempt; anything space-related is bloody hard, and you've got to expect failures on brand new, untested hardware.
On the other hand, if I were one of the Russian engineers responsible for the first stage, I'd be pretty pleased with the successful Angara flight test.
(Although I'm not sure if I was the only one who saw the launch video, and saw the first stage pitch suddenly before clearing the tower and then pitch in the opposite direction. Didn't look good...)
I don't always make a bunch of basic spelling mistakes in my submissions to Slashdot, but when I do, I drink Dos Equis.

What is the difference between a rocket and missile test?
Depends on whether it is done below or above the 38th Parallel.
South Korea bumbled its way into the Asian space race Tuesday...It seems that the KSLV-1 first stage, developed by the experienced Russians, worked perfectly. However, the rocket's Korean-made second stage, which was supposed to carry and push the satellite into its place, apparently had some issues.

In a video session disclosed only to a limited number of reporters Wednesday, the Korea Aerospace Research Institute (KARI), the country's space agency, revealed footage taken from two built-in cameras planted on the KSLV-1 second stage...The second-stage tumbled back to Earth, and the satellite soon followed, as the remaining fairing was heavy enough to prevent the rocket from achieving desired speed and pushing the satellite to a speed faster than 8 kilometers per second that was required for the spacecraft to remain in orbit,'' Park Jeong-joo, who heads KARI's KSLV systems unit, said.

Russian officials cited by "Interfax" are claiming the vehicle failed during second stage flight.

Does your payload blow shit up or does it take pictures? You don't think there's a difference between the two? Don't give me shit about military applications of spy satellites. There's a fundamental difference.
