A lot was made of the launch, but everyone quickly realized that it was all much ado about nothing.
Late last week, North Korea launched its controversial Unha-3 rocket despite heavy protests from some of the worlds largest powers, including the U.S., Britain, and Japan. After about one minute of flight, though, the 100-foot rocket exploded and its parts fell into the Yellow Sea.

The Unha-3, based on the TaepoDong-2 missile, was jointly developed by North Korean and Iranian rocket engineers. It was meant to fly south, to the west of the Korean peninsula between Japan and the Philippines. Upon review of its flight, experts believe that the rocket likely exploded due to severe vibrations at Max Q, or maximum dynamic air pressure.
More specifically, Max Q is the point where aerodynamic stress on the rocket as it is traveling through the atmosphere is at its greatest. The rocket created by the North Korea-Iran team was unable to throttle itself up or down to relieve said stresses and as a result, it splintered into several pieces and fell into the water below.
According to US NORTHCOM, the actual launch of the rocket lasted just a few minutes, before first stage pieces dropped into the sea about 102.5 miles west of Seoul, South Korea; the agency also reported that the missiles other two stages failed as well, luckily with no debris falling on land.
Insight on the launch
The South Korean government estimates that their controversial neighbor to the north spent an estimated $450 million (USD) on the failed test.
The timing of the launch was meant to honor the 100th anniversary of Kim Il-sungs birth, grandfather to Kim Jong-un, North Koreas current dictator. There was a lot of tension surrounding the event, with many of the aforementioned countries claiming that a satellite attached to the rocket was a cover for what was clearly a long-range missile test. Their argument was that the test violated UN resolutions on nuclear and missile activity.
According to North Korea, however, the launch was meant to place a satellite into a 310-mile circular polar orbit.
Failure fallout
The failure of the launch is made even more humiliating because of all the attention that the country had received surrounding the event itself. The government even went so far as to invite a group of foreign press to visit the launch site and missile command and control center prior to the rockets blastoff.
Many of those invited reported afterwards that government briefers were no longer available for comment after the rocket exploded. It is now feared that the scientists and engineers associated with the rocket will face prison sentences or death as scapegoats for the projects failure.
” Why did North Koreas rocket launch fail? “
‘North Korea’ - ‘fail’ — asked and answered...
That'll do wonders for the esprit de corps of the bunch tasked with designing/launching the next one.
I'm real worried.
On the plus side I don't think the 'B' team will fare much better. They should probably offer them a cheeseburger as a reward.
It would have been absolutely hilarious if it had veered off course and landed in China.
The Germans had a number of failures before they succeeded at Peenemunde. One thing they did have was great teamwork and a relative absence of political interference. (Von Braun was arrested by the Gestapo once, but his boss managed to get him released. For such a high profile program, they had relatively little political interference.)
Anyone want to lay a bet that a member of the Iranian team was Israeli?
LOVE the donger
Vanguard, Apollo 1, Challenger, Columbia...
We had our share of failures. Blessedly few, though, considering the mind-boggling complexity of the whole endeavor.
It doesn’t help you get better if you shoot all of the top scientists and engineers and have to start all over. That kind of brain drain is hard to overcome. (pun intended)
Which would be made from....
(Consider at this point the example of the learning flatworms.)
Having Iranian help with their missile program begs the question why have they not transitioned to solid fuel and eliminated all of the jiggity pokery required to make liquid fuel work? The Iranians have already done it and our non-cruse missiles are all solid fueled.

Having worked on large scale technical efforts, I understand the need to set goals, have schedules and consequences. I also recall at the end of the Cold War, with lots of lay-offs, the fear of failure had a distinctly counter-productive effect. No one would own up to mistakes, or take any risks. More time and money was spent on recriminations and blame ducking than solving problems and getting things done.
We can only hope this sets them back a good while.
It’s a lot easier to precisely control a liquid fueled rocket, plus you probably get better energy density. The advantage of solid fuel is that it is a “sealed round”, you take it off the shelf and shoot it. Liquid fuel needs maintenance and lead time to fuel. Soviet ICBMs were liquid fueled and were nightmares in terms of maintenance.
Maybe Obama would share some of the Dog Meat in his freezer.
