A picture is worth a thousand words, ----- even if none of then are right!

It appears to be increasingly important to prove the moon landings were fake.
What is there to be gained?

Blistered paint from heat! Why only some spots?
More likely a retouched area that blistered form outgassing in the vacuum.

It appears that some are trying to outsmart a group of rocket scientists that put more total hours into a project than a single person could over their lifespan.
If you dedicated your life to first studying all the aspects of these space missions and all the issues of space flight, then you would likely understand the pictures much better.
Missing moon rocks? In fact many of the real moon rocks were destroyed in test, ended up in a personal collection, not displayed as the real rock was stolen or feared might be and many other happenings.

So how does this story end when for every proof of fakery there are several additional proofs it was in fact real.
You really think that only the US was able to monitor the mission and no other country intercepted the video directly from its source as real time proof.

If you do then you probably were not old enough to understand the state of the world at that time or simply played to many video games and cannot distinguish reality.

Very well said...

That is correct PW,and the reason for my question. All three pictures i posted are of the command module,so i am just asking as to how that can be,as the ones that look like the command module is covered in duct tape,is as they were leaving earth on the way to the moon. The last picture is taken when they arrive at the moon,and are now in lunar orbit. The other pictures in the earth orbit section,also show big chunk's broken off around the window frame's,but when they get to the moon,we see a nice shinny,well built command module with no broken window frame's. How can this be?.

Brad

"Broken window frame", seriously?  Even with all that money available, is it your theory that they could not even afford a decent looking "mock-up" for their Stanley Kubrik'esque production?  Don't you think the Russians have had their imaging experts look at all aspects of Apollo?  I would wager even the Chinese are looking at everything Apollo as something to improve upon for their upcoming manned moon missions (although I see even they are being called out as fakers regarding their current space program, it never ends...).   

A lot of engineering went into everything Apollo, more than most can even begin to comprehend.  Even strips of tape were laid down according to a drawing.  When you see something you think to be unusual, you can rest assured it is only because you do not understand exactly what or why it is.

However, although we may strive for perfection, it is rarely achieved...

Looking at another close up of the service module in lunar orbit,we can see blistering of paint arount
the circled areas. This would mean some vary warm temperatures some where along the journey to the moon.
I am no rocket scientist just a dumb engineer but I would suggest if you look at the nozzle directly to the right of the paint blistering and ask yourself where the heat coming out of that nozzle when burning would hit the surface of the service module you maybe able to hazard at a  guess as to why the paint is blistering.  Maybe they were doing a blast demo for the cameras.

That is very unlikely.  The reaction control thrusters only fire in short bursts and are not aimed at the ship.

Okay here we go....

Quote
I did not run with it-->i did what you do every time you spend your time looking for other peoples mistakes, i corrected your incorrect attempt at explaining as to why the flag wavered. To say that the moons gravitational acceleration has nothing to do with it--well that just go's to show how stupid you can be some times. If it was the same sort of thing in a different situation,you would tear strips of those trying to peddle such rubbish. But as it is to do with the moon landing's that you firmly believe in,all your sense of reality has been put aside,and you now resort to idiotic explanations to try and justify the impossible <--this can be clearly seen,and hence my saying-the need to believe out weighs the need to know the truth.

The moon's gravity has "nothing to do with it" because you can ignore it and still make a valid case.  Even if there is no gravity, if a 130 kg mass hits the ground at a certain speed there will be a big thud.  I am intentionally simplifying because you can in this case.  I am ignoring the astronaut's legs acting as a spring.  I will repeat to you that you bringing up the equivalent weight of the astronaut in the moon's gravitational field is ridiculous because the important thing to realize is that it's the combined mass of the astronaut and his space suit that counts and not his weight.  If you can't acknowledge this then you are just being ridiculous.

I wasn't aware that the space suit was giving off gas to keep the astronaut cool like PW explained.  I have to admit that I never thought about how the space suit disposed of excess heat even though I knew that there was a water lining up against the astronaut's skin to remove heat and prevent him from sweating.  There are only so many things that you can ponder.

Now that I know that the space suit was off-gassing by sublimating ice to remove heat, I am going to drop my explanation and go with PW's explanation.  I was hedging my bets by going with the "ground thump" explanation because that's the only one that I was aware of that solved the mystery.

See, it's not that hard to admit that you are wrong.   Are you up to the challenge?

Quote
Absolute rubbish MH,and you know it. Anyone with half a brain can clearly see that your talking crap. So now it is up to you to prove your theory. Now you need to go and find on the world wide web,proof of your ridiculous claim. Go watch the video again MH,and point out the pole moving. You will not find one shred of evidence to back up your stupid claim,just like there is no evidence to back up NASA's and the governments claim that man walked on the moon.

There is still some merit to what I said and even though I am now siding with PW's explanation, you can't be 100% sure.  There is nothing for me to prove.  I don't know the geology of the moon's surface.  I know they did these types of tests, I believe most moon missions left seismographs in place.  You seem to be arguing that what is essentially a sound wave traveling through the upper surface of the moon's crust is "absolute rubbish."  Have you ever experienced an earthquake or do you believe that's all Hollywood special effects?  One more time, your line of "anti-reasoning" is baffling.

Quote
To bad the flag's were not made from nylon 6 MH--another misdirection.
Quote:  Dennis Lacarrubba, whose New Jersey-based company, Annin, made the flag and sold it to NASA for $5.50 in 1969, considers what might happen to an ordinary nylon flag left outside for 39 years on Earth, let alone on the moon. He thinks for a few seconds. “I can’t believe there would be anything left,” he concludes. “I gotta be honest with you. It’s gonna be ashes.”
Quote: For forty-odd years, the flags have been exposed to the full fury of the Moon’s environment – alternating 14 days of searing sunlight and 100° C heat with 14 days of numbing

I don't even know what kind of point you are trying to make here.  I think it boils down to this:  A nylon flag was planted on the moon.  It looked fine for the week or less that the astronauts where there, but over an extended period of time the sun's rays, especially the UV rays, degraded the flag and washed out the colours.  Big deal.

Quote
MH-if you cant tell what that type of nylon material looks like when it's right in your face,then you need an optical check. But im guessing you did not use the link i provided,or did any research of your own to check out other close up shot's of the flag. You would have done the opposite to what you are telling me to do,and just sat in your rocking chair,and waited for others to do the work for you

I am willing to bet you that nylon, rayon, cotton, or woven plastic fabric, or woven metal fabric would all look essentially identical in a photograph.  But that's something that you seemingly can't grasp or will refuse to acknowledge.  I have done my fair share of work and if anybody wants to cut corners and not do research take a look in the mirror because you do that quite often when you do an experiment.

Quote
A bad scientist is like the many we have to day--dare not step out of the field of science into the realm of reality. A bad scientist is one that is bias as to what he thinks is correct,and what actually is correct. Have you not ever bought an off the shelf nylon flag MH? How is the resolution of the pic below?--meet your need's MH. And wait until you get a gander at the next set of pics MH--im guessing you will not see the very obvious duct tape plastered all over the CSM-the space craft that is suppose to have carried man to the moon and back,and then survive the extreme heat of re entry.

You definitely need to step into the realm of reality.  Horror of horrors, "duct tape."  Note you are saying "obvious duct tape" because you are falling into your trap again.  You are cutting corners and saying it is "duct tape" without actually knowing what it really is.  It's the heat shield that has to survive the extreme heat of reentry, not the duct tape.

Quote
Of course you wont read the thread verbatim,and that is why you make continual mistakes.

If I make a mistake I'll acknowledge it.  If you make a mistake you turn blue, and there have been many.

What is ridiculous MH is the fact that you think there is no difference between a mass 1/6th that of a second mass impacting the ground with an acceleration of G that is also 1/6th that of earth.
Do you know how to work out the impact energy difference between what that impact would be here on earth,and what it would be on the moon MH?.
Now-who is being ridiculous?.

Puppets on string's MH ::)
So you have decided to drop your ridiculous explanation,and head off and join the gang that you deem has a better explanation. But you were so sure your explanation was the only possible explanation MH--it's right here on the thread.
You just jumped out of the pot,and into the fire--to blindly go where many have been before. ;)
First,not enough force from a 2000lb thrust from a rocket engine to make a crater in the moons surface,because the vacuum of space dissipates the gasses to quickly,but a small !puff! of ejected water from a space suit manages to maintain a concentrated jet stream over some distance that has enough force to make a flag waver :o
Lol,you guys just crack me up. I am guessing that both of you know what happens to water as soon as it is subjected to an extreme vacuum as would be encountered on the moon.?.
And you say that im clutching at straw's lol.

And for you MH,it dose not seem that hard for you to disregard something you believe in ,to run off and join the camp that seems to have greener pastures.

There are only a couple of you that stand alone here,and your not one of them MH--your a puppet on a string.

Lol-still trying to peddle that one MH?
What makes 100% sense,it the air disturbance made by the passing astronaut being the cause for the wavering flag. We can replicate that with ease here on earth,and see that it is the most logical explanation there is--and the only one that is plausible.

My point is this.
PW seems to think that heat was going to be a very big issue when i claimed that i could build a lunar rover that was twice the machine ,at half the cost.
Now heat dose not seem to be an issue,as a bloody nylon flag was able to withstand this heat with no problem at all.
So what;s it going to be--is there an extreme heat issue with the sun striking objects on the moon-or not?. The !off the shelf! nylon flag seems to hold up to the task quite well.

The short answer is the impact energy would be the same.   You clearly haven't read or understood what I said and you are still hooked up on the moon's gravity.  But what you really need to do is unscramble what you are saying above and restate it in a coherent way that makes sense.

Off-gassing from the space suit and a small localized moon tremor from the astronaut's impact on the lunar surface are two perfectly reasonable explanations for the waving flag.  I learned something the other day and changed my view and you seem to think there is something wrong with that.  You don't dare touch PW's explanation because you were ignorant of it just like me, and that probably applies to 100% of the moon conspiracy theorists when discussing the flag.  You are making yourself look like a fool when you flat-out deny the possibility of a localized moon tremor.

Hi TK
Is there a specific fact you are focusing on with this collection of videos.  I could point to 100+ videos saying we faked the moon landings but I think it would be more logical if we focus on a specific piece of evidence.

It would probably make more sense if we treated this like a legal case, Tinman versus NASA. The accusation "NASA lied when they said they walked on the moon." 

This way Tinman who is making the accusation or others you support this position can present a piece of evidence saying this proves we could not have gone to the moon because of XXXXXX.  They can then prove their point with the supporting facts and data.  The defense can then state sorry you are wrong here is our counter evidence and prove their point, with facts and data. We can then move onto the next point.

I think if we keep this at a point by point bases observers can then make an informed opinion using an evidence based reasoning approach.

Tinman,

I have the answers to the questions you posed regarding the discrepancies in the images you noted.

The outer wall of the command module is made up of three major heat shields.  The aft heat shield is the rear most disc shaped heat shield that most people are familiar with.  The other two heat shields are the "crew compartment" and "upper" heat shields, which is pretty much everything in front of the aft heat shield.  Those two heat shields are made of a phenolic composite material.  This is somewhat similar to the material used in the old brown colored PCB's before FR4 became more common.  The heat of re-entry would melt most metals so phenolic was used.  Although being what most consider a type of plastic or epoxy like resin, phenolic does not burn or melt.  When heated, phenolic will get white hot, char (turn to ash), and then shed the charred material.  This process insulates, sinks, and removes heat.  Of course, if the heat is applied long enough or the phenolic is thin enough, extreme heat will eventually wear (not burn) thru the material.  The thickness required is therefore determined by the expected heat and duration.  This type of heat shield is called an "ablative" heat shield because the material "ablates" or is "destroyed" as it shields from heat.  The aft heat shield is also an ablative heat shield but is constructed somewhat differently.

Anyway, exclusive of the aft heat shield, the phenolic material used for the CM 's varied in color from an ugly gray to orange brown color.  Some of the early Bloc-1 CM's were painted white.  The Bloc-2 Cm's however, instead of being painted white, were covered with very thin aluminized Mylar (PET) tape, which gave them their shiny appearance.  When looking at the Mylar tape covered CM's under most lighting conditions and/or from a distance, they appear uniformly shiny as if constructed from or covered in metal.  But, under certain lighting angles, the individual runs of tape, and any nicked areas patched with smaller pieces of tape, become quite visible (as evidenced by your images).  This is a mostly optical phenomenon due to the tape being so thin.

Regarding your "cracked window frame", a somewhat makeshift attempt at adding a glare shield to the edge of those windows was made using the Mylar tape.  Although, as you have noticed, the tape tore at the edges, the remaining flap did cut down on glare caused by light striking the .7" thick fused silicon outer window at a shallow angle.

Excluding the launch vehicle, in an earlier post I stated that Apollo consisted of three sections, the SM, CM, and LM.  However, an often overlooked section is the Launch Escape System (LES).  This attached to the top of the CM using 4 legs attached with explosive (frangible) bolts.  Besides pulling the CM away from the rocket during an emergency, the LES had a tightly fitting cork and fiberglass shell that covered most of the CM.  The shell of the LES saw the bulk of the aerodynamic forces during launch and protected the CM (and tape) from those forces as well as from the launch heat generated by air friction, which could reach 1200F. 

If you go to your flickr site and look at images toward the end of AS17 cassette 145, you will see the CM in a few different lighting angles where you can see the long runs of Mylar tape used to cover the bulk of the two heat shields.  Perusing other cassettes and images will provide you with additional evidence in support of this explanation.

Thanks for the info PW-makes sense.
I am still a little lost as to how the tape was multi colored when leaving earth, and ended up looking like sjinny chrome by the time they got to the moon.

The short answer is the impact energy would be the same.   You clearly haven't read or understood what I said and you are still hooked up on the moon's gravity.  But what you really need to do is unscramble what you are saying above and restate it in a coherent way that makes sense.

Off-gassing from the space suit and a small localized moon tremor from the astronaut's impact on the lunar surface are two perfectly reasonable explanations for the waving flag.  I learned something the other day and changed my view and you seem to think there is something wrong with that.  You don't dare touch PW's explanation because you were ignorant of it just like me, and that probably applies to 100% of the moon conspiracy theorists when discussing the flag.  You are making yourself look like a fool when you flat-out deny the possibility of a localized moon tremor.

The above is a ridiculous comparison that is completely invalid and makes no sense.  It's just another item to add to that list that I posted of crazy things that you said.

It's laughable that you accuse me of being a puppet on a string because I learned something new and adapted my views.

If you believe the impact energy of a mass is going to be the same on the moon as it is here on earth, then you need help.
If you now think that moving over to PWs reason for the flag wavering, then you have just made another mistake. Before blindly believing PWs explanation, you should maybe go do some research into what PW said. But im guessing you wont, and im also guessing that you also paid no attention to what I said about the power of observation.

I have never seen you get so much so wrong in one thread.

Thanks for the info PW-makes sense.

Tinman,

That is an optical property of thin films.  Think soap bubbles and oil films on water...

If, when you discuss this topic, you could put a coherent sentence together that makes sense and demonstrates you are aware of what the issues are, it would make a huge difference.

The impact energy of an identical mass hitting the Earth or the moon will be the same if the two impact velocities are the same.  It's rocket science.

If you disagree with what PW said about the sublimation of the ice then make your case.

Just an interesting factoid I'd like to share regarding thermal management on the rover.

Figuring out a way to keep the electronics on the rover cool while not adding an undesired amount of weight or complexity was an engineering challenge.  Various methods were considered but the incredibly simple and very reliable method selected should at least inspire some degree of awe.

The enclosure housing the electronics was insulated and shielded to reduce solar flux.  However, the heat generated by the electronics would have caused the internal temperature of that well insulated enclosure to rise to an unacceptably high temperature because the heat dissipated by the electronics was unable to escape thru the insulation.

The brilliant, and very elegant solution arrived at, was to completely fill the electronics enclosure with molten wax.  The wax became solid when it cooled.  As the rover was operated, the heat generated by the electronics would slowly cause the wax to melt, that is, change phase from solid to liquid.  This process took advantage of the latent heat of fusion, and could absorb fairly large quantities of heat while remaining at a fixed temperature.  When the rover was parked, an insulated lid on the electronics enclosure would be raised to expose the wax filled enclosure.  The insulated lid, when open, also acted as a sunshade and shaded the wax from the sun allowing the wax to radiate its heat into the cold blackness of space and re-solidify.  As well, the rover had to be strategically parked to ensure that the lid shaded the wax filled enclosure when the lid was open.  Just before use, the lid was closed and it was off to the races.

Imagine the amount of research, science, and engineering required just to select the proper wax formulation.
