South Korea's first space launch to take place 30 July

No...we are threatening North Korea for developing something with less than 1/10th of the power because it's run by a raving lunatic that likes play with nuclear warheads. Grown ups don't like their children play with dangerous toys, and someone needs to counter children like North Korea and spank them for being naughty.

And what gives us the right to decide that North Korea is a naughty child? Just because they don't agree with us? That's not very democratic, is it?
Or perhaps it's because of this mythical concept of freedom, and their civilian's lack of freedom. Then again, we impose so many sanctions on them that surely we're breaching the freedoms of their country. It's immensely hypocritical that we complain about all these other countries whilst our own are, in some ways, no better.

The "naughty child" part probably relates to the international perception that the North Korean government is more likely than the established nuclear powers to initiate a first use of nuclear weapons should they gain the ability to deliver them at will. In layman's terms, they are considered to be more "trigger-happy" with nukes than most other nations.

Russia says, considering they're the engineers doing this launch. Your trolling is weak.

My design prevents me from trolling, but allows for the occasional stupid post every now and again... :rofl:

If unjustified weapons release (nuclear or otherwise) is a reason to treat a country as a naughty child then I guess we'll have to impose sanctions on about 90% of the world, including ourselves.:lol:

likes play with nuclear warheads.

Nuclear weapon detonations/tests:

NK: 2 if you count the failure

US: 1,056-ish, including the only uses in war.

Who likes to play with weapons?

I think you left out the former USSR, China, France, UK, South Africa? A few more I can't remember.

Khrunichev said that their first stage worked well, but that there was a failure in the second stage, causing the satellite to reach no orbit: http://forum.nasaspaceflight.com/index.php?topic=13849.msg464999#msg464999

Is it me, or did the KSLV seem to "sway" a bit at lift-off and the first few seconds afterwards?

I love how their coundown timer is all like futuristic fancy 3D... and then the rocket fails :lol::rofl:

NARO SPACE CENTER, South Korea, Aug. 26 (Yonhap) -- A South Korean satellite carried by a rocket launched earlier this week was lost shortly after blastoff due to problems in the fairing assembly system, the government said Wednesday.

The Ministry of Education, Science and Technology said that while the first and second stage rockets of the Korea Space Launch Vehicle-1 (KSLV-1) separated as planned after liftoff from the Naro Space Center at 5 p.m. on Tuesday, one of the two fairings covering the satellite did not fall off properly.

Only one fairing was ejected 216 seconds after launch with the other section remaining in place until the Science and Technology Satellite-2 (STSAT-2) separated from the second stage rocket 540 seconds into the flight, the ministry in charge of the country's science and technology policies said.

"The fairings weigh four times more than the scientific satellite making it effectively impossible for the second stage rocket to generate the necessary thrust to keep the satellite in orbit," Vice Science and Technology Minister Kim Jung-hyun was quoted as saying by Yonhap News Agency.

He added that the extra weight also affected stabilization and navigational control that caused the rocket to steer upwards and the satellite to be released at an altitude of 387km, far higher than the planned 302km.

"The second fairing fell off 540 seconds after launch but by this time the speed of the rocket and satellite had fallen to 6.2km per second," the policymaker said. A satellite needs to maintain a speed of at least 8km per second to stay in orbit.

He said that the satellite probably fell back toward Earth and was destroyed in the atmosphere, adding it may be hard to find any remnants of the 100kg satellite.

SEOUL, Aug. 25 (Yonhap) -- President Lee Myung-bak called Tuesday for renewed and redoubled efforts to advance the country's space technology, calling South Korea's failed first rocket launch a "half success."

"We can say it was half successful, though the satellite failed to enter orbit," Lee said in a Cabinet meeting that began shortly after the rocket launch at 5 p.m.

"We must realize our dream of becoming a leading country in space technology, even if it takes an eighth attempt after seven failures or a ninth attempt after eight failures," the president was quoted as saying by his spokesman, Lee Dong-kwan.

Nice test for the Angara's 1st stage, anyway. Some improvement is needed yet to remove this scary swaying over the launch pad, though.

The fairing weighs 4 times as much as the sat?
Has anyone told those guys they're not supposed to use lead?

No, it's just a feather weight sat:

Securing something more valuable against the high launch risks?

"One possibility is that both of the explosives used to separate the two fairings, went off simultaneously at 216 seconds after blastoff, but one of the fairings remained attached for the next 324 seconds due to mechanical problems with the fairing," Lee said during a press briefing.



"Another possibility is one explosive detonated on time at 216 seconds, but the other went off abnormally at 540 seconds after liftoff, which is around the time when the satellite separated from the rocket."



During its analysis, the panel also found that there was the possibility of a clash between the second-stage rocket and the satellite right after the satellite separated.



"After we analyzed vibration-related data, there was some vibration detected (after the satellite separated). So we thought there is a possibility that the vibration was caused by some clash between the tumbling rocket and the satellite," Lee said.
