[QUOTE=l33tkill;38820976]I don't believe that this is true. I would assess the main components aren't set up at the launch site for a while until a launch cycle has started to prevent weather damage. Otherwise news agencies would have pointed out the TD-2 a long time ago.[/QUOTE] [url]http://www.stimson.org/spotlight/krepon-and-romberg-on-north-koreas-planned-satellite-launch/[/url] the reason I said april was because the image url said april, but this article was written in march- it was talking about the plan being for april. I've seen a bunch of higher res graphics floating around of the launch vessel, all identical to this, so I presume maybe they set it up and tried doing a launch but backed out that time more images from much more reliable sources, from that time [t]http://static1.businessinsider.com/image/4f85b06feab8ea234700002b-900/currently-it-stands-at-sohae-satellite-station-in-tongchang-ri-north-korea.jpg[/t] [t]http://s1.ibtimes.com/sites/www.ibtimes.com/files/styles/article_large/public/2012/04/08/259599-north-korea-opens-it-doors-for-nuclear-satellite-launch.jpg[/t] and of course recent [t]http://i.telegraph.co.uk/multimedia/archive/02170/Kim-Jong-Un_2170890b.jpg[/t] [t]http://binaryapi.ap.org/390d21a8d23547e5a595e608167c63a2/460x.jpg[/t]
That poor rocket looks like it wanted to die.

North Korea, with their technology, could launch an intercontinental ballistic missile and have it make it all the way to Los Angeles. [I][sp]if it was launched from Santa Monica[/sp][/I]

Otherwise news agencies would have pointed out the TD-2 a long time ago. [editline]13DEC12[/editline] And by launch cycle I mean C2 vans, and POL trucks making it's way to the launch site all at the same time.[/QUOTE] We are talking about a space agency that let the worlds journalists see the rocket within ~200 meters and the payload leading up the previous attempt. From the video I saw the guy was saying that NASA spend days attaching the payload but they saw it just hours before the planned launch. So you cannot expect them to do things "properly" Perhaps that's why the previous one failed.
[QUOTE=BreenIsALie;38815198]Very easily A slight push in one direction and you start to tumble. Not having any (significant) resistance makes it a bit annoying[/QUOTE] Canada's old Anik satellites are doing that right now. They remained operating until their control jets ran out of fuel. Excluding battery power they're still online when they are in the sunlight however they're tumbling so you can't get a signal lock on them.
[QUOTE=Garik;38816141]Yeah, but tumbling out of control as in losing altitude. How high do you have to go to be not affected by wind resistance?[/QUOTE] Significantly higher than the ISS, which regularly has to use engines to push itself back to the proper orbit. The giant solar panels don't help.
[QUOTE=Fatfatfatty;38814687]They should have invested in an SAS module[/QUOTE] All my rockets kept pinwheeling hilariously out of control until I realized what that module was for. Never again. :v:
[QUOTE=Camundongo;38816124]Although looking at the tracking website, it looks like it's periapsis is falling as well - the site lists it as 505.5 Km, but it went down to 501 Km, so I'm guessing it might not stay up for a hugely long time.[/QUOTE] This doesn't mean it's on its way down. Unlike KSP, real life gravity is not uniform, orbital data changes all the time. (It will eventually fall down due to atmosphere resistance though, but that takes longer than a week)

US using those laser beam x-ray gamma waves to take down satellites on orbit.

[QUOTE=Camundongo;38833389]Actually I was just suggesting it's in an unstable orbit and will probably probably end up getting snagged by atmospheric resistance in a few months.[/QUOTE] Please explain the concept of an unstable orbit. This satellites orbit is in every way above the ISS, so there's no reason to say it won't stay up for a while. Being out of control doesn't change that. Don't get me wrong, it will definitely fall down eventually, as everything in LEO requires occasional help to stay in orbit, due to atmospheric drag, but a lot of people seem to think it will suddenly fall down overnight due to NK's incompetence. [editline]15th December 2012[/editline] A few months is probably not a bad guess though.

That's the only kind of moderately 'unstable' orbit there is. But if that's your definition, then our pride and glory, the ISS, is in an unstable orbit as well. TBH this whole news article and thread are filled with shitty satellite lingo.
I bet it's not a satellite but instead is actually a crumpled ball of all the U.N.'s angry letters.
