Moon Walkers.

[tinman]

No offense Tinman but I can't believe NASA built that.  This looks like something you through together with some mates in the back paddock after a couple beers. That is really a rough job and you need to learn how to use a rivet gun cause you buckled the crap out of sheet metal. If I was your high school metal work teacher I would have given you an F for that piece of garbage. 

Is that duct tape ?

Lol--no,they are the real deal from NASA--believe it or not. These are the multi million dollar machines that landed man safely on the moon,and then lifted them back into space lol.
This site has every picture ever taken by NASA's apollo missions. I have spent a lot of time going through them,and i can tell you now-the moon walkers were a hoax. In this archive of pictures,wou will see magic happen,from self levitating lunar rover's,to lunar modules that change positions all by them self. The images that are shown on this video of the apollo 17 mission,are on there as well-as clear as day.

Here is the link to the apollo 17 mission photographs. Click on each image,and it will expand the image. You can see so much detail in these images-even at exploded views.
The site has all the apollo missions on it,so take a day,and enjoy the hoax unravel.

Oh,and check out the plastic/nylon flag's in HD. Some say they were an aluminum foil,but as you can see--good old nylon/plastic material,with standard stitching. They seem to hold up well to the extreme temperature's-->just like that photograph in the plastic bag did.

The inner and outer walls of the LEM were very thin.  Between the inner wall and the outer wall, which is actually the micrometeorite shield panels seen on the outside of the LEM in the images posted, was a thermal blanket.  The outer micrometeroite shield and thermal blanket were supported away from the inner skin by standoffs.  On the way to the moon, the outer micrometerorite shield of the LEM saw large temperature variations which caused thermal expansion and contraction of those outer panels.  They were intentionally mounted to allow for this (and reduce thermal conduction to the inner skin). Even so, being attached at the standoffs produced some degree of inconsequential buckling. Keep in mind the LEM never saw aerodynamic loads, needed to be as light as possible, and in the end was disposable.

Astronauts have remarked, somewhat tongue in cheek, about how thin even the inner walls of the LEM were and that they were a bit concerned over how easily they might be punctured.  Nothing was made any heavier than it absolutely had to be.  Anywhere weight could be saved it was.  Space is not easy.

Here is some cool design info, wall construction is around page 7 and 8 or so:

Just for grins, check out the explosive devices discussed toward the end of the document.

Added:  From the linked document, those outer micrometeorite panels, minus additional thermal coatings (i.e., paint) were made from aluminum that varied between .004" and .008" thick, which is similar to the thickness of a beer can.  I believe I read somewhere that the inner skin was only on the high side of those thickness numbers or just a tad bit more.

I want some of that thermal blanket. In my house, when the outside temp. gets over 390 F., my cooling bill gets too high. I can imagine how, with only a wall thickness of apparently 4 inches or so just like my house is now, I can have a comfortable life without AC like in the lander.

Thanks for the reference to beer can thickness. Now I have something I can relate to.

Did we ever figure out how they survived the terrible cold of night on the Moon? Maybe on the Moon they have shorter nights?

Insulation dear Watson lol.

Im more interested in what the differential pressure was between the inside and outside of the space suits. Looking at the first image,it would appear as though there was none--note all the wrinkles in the suit. The second image is what i would expect to see lol.

   Nobody seems to have thought about what Russia were doing,
   I'll bet they had their beady eyes on every move.

A mechanical engineer of any kind, which apparently you are not, would be able to look at the design of the LEM, including those outer panels you scoff at, and appreciate the high degree of research, design, and engineering that went into the design solution arrived at.  The outer panels are like a lightweight tent suspended away from the inner structures.  They are connected to the inner structure by standoffs using as few of them as possible to reduce thermal conduction between the outer and inner walls.  The outer panels were overlapped, somewhat like shingles, and where they overlapped, the panels were chemically milled to reduce their thickness to reduce unnecessary weight. 

During the trip to the moon, the CM and LM were slowly rotated to prevent heat from building excessively on the sun facing side.  Because of this, the thin outer panels saw heating and cooling differentials that made them expand and contract.

I actually wasted a few moments of my life and watched the "analysis" of the first two images discussed in this video.  They are very keen on being focused on and discussing, the background, but it is the foreground that one should instead pay attention to.

And just exactly how can you determine what the flag is made from by just looking at it?

For work that I do here I have an entire library of woven metal mesh.  I have stainless steel, bronze, brass, copper, aluminum, Monel, Nickel and a few more exotic materials with weaves up 1200 wires per inch.  Some of these mesh are more flexible than and feel softer than a lot of synthetic cloth weaves. 

NASA used a lot of woven mesh in various applications.  Some of the most expensive, and at the time, leading edge technology, were used in the glove of the space suit.  On the LEM, for example, the darker material of thermal insulation seen on the outside in the areas of the nozzle exhaust incorporated a nickle mesh.

When I look at your flag closeup, all I can see is that it appears that it might be made from a woven material, or possibly even a non-woven material.  Apparently, I do not have the same magic powers (or closed mindedness) as you do and cannot tell what that material is from just looking at the image.
