North Korea's Satellite Tumbling In Orbit 257

schwit1 writes: U.S. Defense officials stated Tuesday that the satellite that North Korea launched on Sunday is now tumbling in orbit and is useless. Do not take comfort from this failure. North Korea has demonstrated that it can put payloads in orbit. From this achievement it is a very short leap to aiming those payloads to impact any continent on Earth. They might not be able to aim that impact very accurately, but if you want to ignite an atomic bomb somewhere, you don't have to be very accurate.

    Now and for decades to come, North Korea would be very unlikely to use an ICBM/IRBM to launch a nuclear bomb. The missile might not work and neither might the payload after being subjected to the stresses of lift-off and re-entry. Assuming they wanted to blow up Washington, DC, I should think that they would simply smuggle the warhead into the US using the same routes used by smugglers to import carload lots of Cannabis then deliver it using an elderly Toyota purchased on credit . (Be a bit difficult to repossess THAT one when the payments stop).

      I don't think N. Korea can miniaturize their bombs to that degree. It's probably about 10 tons and bomb-looking as hell. A ground burst also limits the damage. The slow nature of deploying it would make it offensive only - if they were attacked it would be too late to use it. They need the opposite, something that could be launched within a few hours in response to an attack. Something that would sting just enough to make the US decide not to invade.

      Actual use would mean suicide, so it's not meant to be used.

        If that's so, it seems to support GP's point. 10 tons is greater than the throw weight of the largest ICBM in history (8800 kg). The Taepodong-2 vehicle's payload capacity at maximum range (which would only reach the western US, btw) is estimated to be 500 kg or less.

        If they want to launch it at us, they've pretty much got to get it small enough to fit in a car.

          That's an excellent point. But my comment about the timeliness of launch still stands. An eventual car bomb attack that may or may not work is a lot less of a deterrent than a couple of dozen ICBMs.

            Yeah, not so much. Not that the Norks wouldn't try that dodge, but fingerprinting nuclear weapons is a thing. Within hours of it's use, we'll know whose it was, or at least who built it.

        • The Taepodong-2 was not an ICBM. It's the space launch vehicle and Taepodong-1 was an earlier, clearly failed attempt. I believe someone made the Taepodong names up, and a decade or more ago we all assumed these were long range missiles rather than something to launch a satellite from.

          True the line between space launch and ICBM seems really thin but this is really a rocket that needs weeks of launch preparation, can be fired from a single place and would only be usable as a really weak single shot, suicide

                In your eagerness to stop the fear mongering you badly understate North Korea's capability. Sure, they can barely feed their people. 20 years ago guys like you declared the same things, that the North's economy and tyranny made scientific accomplishments like nukes and rockets impossible. Since then they've detonated nukes(plural) and launched satellites(plural again). I'm not sure where you've set the bar for 'meaningful' but the North has made succeeded in building nuclear weapons and launching rockets around the world.

Given how brutal, cruel and tyrannical the Godkings inheriting North Korea are, that's small comfort.

                The reality is that if Seoul wasn't housing 10million people within range of North Korean artillery, NATO probably would have removed the Kim dynasty generations ago.

        DPRK is armed to the teeth with conventional weapons and has had 60 years to dig in deep, making a conventional ground assault extremely painful. Not that the US couldn't *win* such a fight should it choose to dedicate the resources, but it would be extremely resource and manpower intensive.

It's obvious that an overthrow of the Kim dynasty will be bloody, I'm inclined to believe that if it happens it will be quick and the violence will be fairly localized and unlikely to flow over the border that much. What WILL be an issue is if the conflict lasts very long and the population starts flooding over the borders as refugees, mostly into China.

      I really, really doubt the leaders actually think it is worth dropping a single missile or two on the US, and expect that there would not be massive retaliation literally destroying their country. The US would not sit back after any kind of attack and reconsider, it would be full speed ahead.

      Instead, what they want is the threat that they could let loose with several missiles if we were to invade them, and it would be difficult to stop them once in the air. That scares the US populace, and makes them think twice about coming and attacking them on the first place. That is why they make such a big show of it all, to make sure we know they have a weapon they could use against us. That, after all, is really the whole premise of nuclear weapons at this point.

        I assume you don't actually know where NK is. Look on a map. Bejing is less than 500miles away. NK shares a border with China. Japan is very close, too. There is no possibility that China would allow the USA to nuke one of its neighbours - not with the possibility of fallout spreading across the region.

        Luckily, your fears are completely unfounded. NK doesn't give a flying *** about the USA. It is more concerned with South Korea and if it was to use a nuke, they already have a target painted large as Seoul is only 30 miles from the NK border - easily reachable by truck in less than an hour. That is their hostage, should anyone attack them. What is far more likely is that they are developing the technology to sell. The launches are just advertising for their capabilities and the people you should be worried about are the ones who hate you and have lots of money. Sadly, that list is quite long: just look at all the countries you've bombed back to the stone age in the past few decades.

That'll do more damage than a nuke hitting DC, and no aim is involved. Off by 100 miles would still be a direct hit, unlike DC.

        There is no real fallout from a high altitude blast. The most damage DPRK could do would be to launch it on an ICBM at South Africa over the US, and detonate it as it's over Kansas.

        Second in damage may be a truck-based ground blast in DC, between the White House and Congress. Should be able to take out both, they are under 2 miles apart. And the damage wouldn't even be much beyond that, leaving DC largely intact, aside from the fallout from a ground blast.

Yes, it won't fry all electronics in the blast radius for all time, but it'll do enough damage to kill more than if they had targeted a city.

    for nuclear weapons with than ten kilotons yield of course extreme accuracy is needed if targeting something a third the world a way, what a stupid thing to write. Do you get your ideas about a nuclear weapon can do from entertainment media?

      Absolutely right, with humans only populating about 1% of the surface of the earth accuracy is not to be ignored.

      The recent meteorite that exploded above Chelyabinsk is estimated to be a 500 kiloton equivalent and that didn't bring the region to its knees.

    North Korea's recently launched satellite has achieved stable orbit but is not believed to have transmitted data back to Earth, U.S. sources said of a launch that has so far failed to convince experts that Pyongyang has significantly advanced its rocket technology.

    Sunday's launch of what North Korea said was an earth observation satellite angered the country's neighbors and the United States, which called it a missile test. It followed Pyongyang's fourth nuclear test in January.

    "It's in a stable orbit now. They got the tumbling under control," a U.S. official said on Tuesday.

      Tumbling refers to a very specific behavior in rotational dynamics. A body is only stable in rotation when it rotates around its minimum or maximum moments of inertia (inertia is a 3x3 matrix, not a single number of even a vector like they teach you in high school). When a body tries to spin around any other axis, it ends up gyrating wildly [youtube.com]. What's happening is the spin axis is trying to align with a stable spin axis, but overshoots and passes right t

    In orbital mechanics 'not very accurate', means 'possibly the sun, maybe the ocean, otherwise some sort of land...assuming it does not burn up in entry'.

  • Have they done re-entry? That was a major stumbling block for the US and Soviet ICBM programmes in the mid 50's. Especially as re-entry needs to be accurate. Unlike the idiotic summary, accuracy is vitally important. A five mile error that results in the obliteration of some countryside and suburbs, rather than a city centre is an outcome no lunatic dictator wants.

    And can they make their physics package, re-entry system, and guidance system light enough for their booster to lift. That was something the
