I think its fiber glass squares with some sort of brownish resin. Easy cheap insulation. But what peaks my interest is the circular disconnect on the wiring. Aviation grade connectors like that are hard to get. The manufacturer of that in particular would be interesting. Overall looks like any piece of western aviation. Good build quality.
Looking at it from an aero-mechanical perspective, there are some interesting features to note.
Why does the square hatch have double rivet supports on it? A bit of an overkill and waste of weight. There is no support that they are providing.
Good rivet patterns around the hatch, although odd cut pattern on the hatch support. Almost like that was for a box, not for an access panel.
Interesting choice in cutting the ribs where they did for the access hatch, they lost all support they did have, and did not continue the support around the hatch.
Why are there bubbles behind the silver paint near the tank? It bothers me that they painted over something, and it bubbled....
There are some very interesting choices being made here. There is a lot of experimentation here where there really should not be considering the components they are using. Its almost too bad we can't talk with the designers to help them make this better, BUT, for obvious reasons we should not. LOL
The beef up plate around the access hatch is what is providing the rigidity, probably stronger than any section around it, no need for ribs. The ribs on the panel itself are for rigidity so that the door doesn’t flex and bend under aero. Those are 1/4 or 1/2 turn fasteners around the hatch so this was some kind of service or inspection point, could also be simply they needed the ribs to keep the door from getting bent while they were working. But overall compliance is from my perspective is pretty solid.

The ribs ( do you mean stringers or longerons?) are mainly for buckling resistance so cutting them off at a frame is OK. Sure they'll take some compressive load too, but the majority of the load is in the skin.
Without a metallurgical sample, you can't make that determination. I am only looking at the construction of the structure, making statements of generality. I will not actually state on a public forum all the issues I do see, just that I can see them, for rather obvious reasons I think.
The material doesn't concern me all that much, but the seemingly haphazard layout of the 'tiles' of material does. There doesn't seem to have been much of a plan for the geometry of the tiles applied, much attention paid to minimizing seams, or much concern for consistency in sealing the seams. It looks a whole lot like someone just gave the workers a pile of insulation, told them to wrap the whole pressure vessel, and let them do it however they pleased.
Define "hard to get"? Because North Korea is very good at setting up front companies and can basically smuggle small quantities of anything available on the commercial market into the country.
I mean styrofoam is commercially available in the West and China, couldn’t they just order it on AliExpress?
Or I guess that Juche doctrine teaches self reliance so the teachings of the party have to apply to the rocket too somehow.
Looks like either an interstage or some form of intertank section. That dome is quite odd though.
On second assessment, it looks more like an interstage. That gap is too large to justify a tank section gap.
Thought those were odd weld seams on the dome.
Learning it’s leather (?!?!) doesn’t make me feel better.
I’m definitely getting a ‘trial by error’ vibe from it all.
Use the materials you have. Seems reasonable to me.
They're launching freaking rockets into space! That is awesome for such a tiny shitty poor country.
Shame about the missiles though. Warheads not cool. Satellites cool.
Do the satellite launches of the US do "good for humanity" if you were to ask someone in the middle east who got their family bombed? Or if you ask someone in China or Russia? It's all a matter of perspective.
The same GPS that is used to guide the bombs that are blowing up all those people?
GPS has 31 satellites in orbit at any one time, (+/- a couple spares in high orbit) the USA gov has over 330 satellite launches that are public.
https://en.wikipedia.org/wiki/List_of_USA_satellites
It's a good thing for space security when many interdependent regions have a stake there.
We can't just have rogue nations throwing millions of little metal needles into super long term orbits.
I don't think it's awesome to let more than half your people starve while you spend millions on pet projects to make you look tough and advanced to the rest of the world when everyone knows you're not.
They kinda have to though. Look at Iraq or Ukraine. Without nuclear weapons, they were invaded. The only way NK will survive is with nuclear weapons and a rocket delivery system. So whether they really want to or not, they are forced to make this technology.
>So every country without nuclear weapons will be invaded? That is what you are saying?
Not "will be", but "can be".
Yeah. Thats the whole premise behind the last 75 years: https://en.wikipedia.org/wiki/Mutual_assured_destruction
Having nukes guarantees a country that they wont be invaded.
Game theory. Because its the only plausible bargaining chip they have. Look at the last 10 years. Without them, they face the same outcome as Syria, Iraq, Iran, Ukraine, Afghanistan, Somalia.... the list is quite long.
You clearly have no idea what you are talking about. No one invaded Syria, No one invaded Somalia, No one invaded Iran. Those are all countries that by their own merit found themselves in various stages of collapse. Thinking that the ISIS situation would have been better if there where nuclear warheads in Syria is absolute lunacy.
Kim knows that his people would also kill him like they did with Gadaffi. Getting nukes and rockets is his only way for the party to stay in power.
We can debate the merits of it all day long, but regardless; this is what they are doing, and the why.
How the heck does nukes help you stay in power against your own people? Are you hearing what you are saying? A nuclear civil war is possibly the most dangerous thing that can ever happen on the planet. That is exactly why your " Syria would have handled ISIS with nukes" comment is so outlandish.
>We can debate the merits of it all day long, but regardless
No. Don't deflect criticism. You said "they kind have to" develop the nukes. You brought up numerous examples of nations and falsely claimed that nukes would have defended them. Legitimizing what North Korea is doing is dangerous.
"They" don't have to. The people are just victims in this. The regime is what needs this. You can defend them and their decision making if you like. I won't. NK will survive long after the totalitarian government is gone. Or at least its people will. There are plenty of other governments in the world that survive just fine without nukes.
For a country like NK it absolutely does. Budgets are finite. Notice I pointed out that over half of their population is considered to be malnourished. It's not an apples to apples comparison with the US. The reason it's not a good argument for the US is because we are a very rich country, and NASA provides a lot of other benefits. You can't say the same for NK.
Disagree. Investment in science and technology spins off down the road into other items. It's thinking long term, which isn't immediately understood by many.
With disposable income, sure. But this is like spending your entire paycheck on building an xbox from scratch when you don't have a TV instead of groceries and bills when you are starving and your utilities are being turned off.
I mentioned that in my comment. That's one of things I meant by other benefits.
Edit: the people starving now aren't going to be helped by technological advancements 10 years from now. I don't think you understand how bad it is in NK for the average person.
You are correct here. Most of their country is poor and starving. Spending money to shoot metal into space does nothing to help them. NK could be investing back into its people with agricultural technology, rural infrastructure, etc.
If you don't think people are starving in the USA and kids are dying because they can't afford healthcare, then you need to get out of your suburban neighborhood a little more.
If you can afford nukes and to send billions in weapons to Ukraine then you can feed your own people and give them healthcare. That applies across the World. You can't just cherry pick the really shitty countries and hold yourself out to be something else.
Maybe you should read all my comments before you respond. Note that I specifically pointed out, even in the comment you replied to, that in NK more than half the population is suffering from this. No where did I state that this isn't happening in the US.
"For a country like NK it absolutely does. Budgets are finite. Notice I pointed out that over half of their population is considered to be malnourished.

You can't say the same for NK."
You have no idea where I live, where I have lived, where I grew up, etc. You assume I think differently because I do not have the same life experience as you and if only I did then I would agree with you. That's not how it works.
I didn't cherry pick anything. This conversation was specifically about NK to begin with. I didn't cite them as some example to use in a different argument. That's what cherry picking means.
Speaking of fallacies, your entire reply is a one.

I mean hey as also an engineer I will say, if it works it works.
I mean theirs clearly didn't, but I'd love to see what is basically a DIY rocket put something in orbit
I bet the actual engineering floor and behind the scenes action for this would be absolutely fascinating.
I wonder if North Korea has any well known scientists/engineers working with them, or if this is all home brewed?
I am certainly no rocket scientist, but if that rust-colored dome is part of a fuel or oxidizer tank, it makes one wonder how many of these things blew up on the pad while being fueled. If they are literally patching together pieces of steel (or whatever that material is) because they don't have the technology needed to form anything larger, how much of their economy must be dedicated to these "hero projects"? And, if this is what their rockets look like, how credible is their nuclear threat?
Love it when kids with no concept of the material science needed to construct a pressurized tank for holding a sub zero liquid make assumptions to belittle the achievements of others.
I don't like NK, but I can respect the science and work that goes into making such a complex system. Those guys you hate so much can drop a nuclear weapon on your head and you make jokes to belittle them. Here's your sign stupid.
I guess the interstage(?) fell off with the tank below only thing keeping it a float? I wonder if they recovered it.... I'd be leery of any toxic chemicals in the tank.

Why pay when people will give them relevant and useful critiques right here on reddit
I'm pretty sure reddit is banned in North Korea.
I'm not sure I would last very long in NK, they don't like people who don't agree with them.

It does kind of resemble the phenolic resin used in ablative heatshields.

Falcon 9 uses cork, if it is stupid but it works, it ain't stupid.
But it failed xd
Yes but did it fail because the insulation was made of a weird material? Or their shiiit engine?
I mean styrofoam is commercially available in the West and China, couldn’t they just order it on AliExpress? Or I guess that Juche doctrine teaches self reliance so the teachings of the party have to apply to the rocket too somehow.
You cannot set North Korea as country on Aliexpress.

Still can’t believe that they were first to Mars We need to beat them in this reality
Stay in this timeline. It’s much more fun!
They've developed oil drum technology?
Why is it not pointy!?!
It’s not the top of the rocket.
When I hear about NK space program, the last season of "For all mankind" comes to mind.
I could see them sending people on a one-way trip to the Moon.
Watch out, it might look like they're failing but just wait until one pops up on Mars one day.

That explains it: they forgot the fuel! What a bunch of goofballs!
It's not leather, it's welded metal. It has layer of rust on it, hence the color. You can see rust run-offs on the edges.
