Interview for a Japanese Program on the Apollo Moon Hoax


Introduction

Two weeks ago, I was contacted by a Japanese production company, asking me if I’d be willing to do a short interview for a program that they are producing – and probably broadcasting – around March or April. In Japan.

I agreed, and I was sent a few different questions to get an idea of what I should prepare. I had only heard of some of them, so I did some research and, as a way to prep, I wrote up “brief” responses. Obviously I wasn’t reading while being recorded, but it was a way to organize my thoughts.

And get a free blog post. So, here are ten interview questions and my responses, as prepared. On the show, they weren’t all asked, and a few additional ones were, so I don’t think I’m pre-empting anything by putting these online. Please note that the questions were originally in Japanese, translated into English, and I have edited them a bit for grammar.

Interview Questions and Answers

1. Why did the moon landing conspiracy surface? Did it start with the 1976 book written by Kaysing Conspiracy?

For anything before the internet era, it’s really hard to pin down the start of anything — all you can do is find the earliest example, but there could always be something before that that you simply could not find.

Bill Kaysing’s book in 1976 was the first book to claim that it was a conspiracy, yes, and the very fringe Flat Earth Society was one of the first organizations to do so in 1980.

However, there are various people who were NASA watchers back during the Apollo era who have variously claimed that even in the late 1960s, there were some people who were claiming that it was all a hoax. But, in terms of contemporary, printed material with a definite copyright date, Kaysing’s book was the first.

2. Do you know what the initial reaction to Kaysing’s book when it was just released was?

[No …]

3. Following the book’s publish, the movie, Capricorn One, was released. Do you think the movie was released because of the public’s initial reaction to the Kaysing’s book?

It’s likely it was written due to general hoax sentiment, not due to Kaysing’s book in particular, but it would be interesting to have gotten a contemporary interview with writer-director Peter Hyams to learn his motivation. He said, “There was one event of really enormous importance that had almost no witnesses. And the only verification we have . . . came from a TV camera.”

It’s important to mention that NASA actually helped with the production of the movie, loaning them equipment as props, including a prototype lunar module. If NASA were trying to cover up an Apollo conspiracy, one might think they would not have helped make a movie about them covering up a Mars landing conspiracy.

Do you know how much attention the book and movie received at that time? Was there any media coverage about it?

I don’t know about the book, but the movie became one of the most successful independent films of 1978.

4. The conspiracy theory surfaced in the 70s, and media brought it back again in the late 1990s and early 2000s, such as FOX’s TV special program, “Conspiracy Theory” and the book, “Dark Moon,” which are about the moon landing conspiracy. Why do you think the media covered this topic again after decades?

I’m not sure, but the 1990s saw a resurgence of missions of the Moon and Mars by the United States. People who believed in the hoax could then use that to gain traction. And, if you find a sympathetic producer, or even one who thinks that they can get ratings by making something so sensational like the FOX docudrama, then you can get your show made.

5. The points that conspiracy theorists bring up: Despite the fact that there was a large amount of thrust, there was no blast crater left on the moon.

There’s no real reason to have expected a “blast crater” in the sense of an explosion. There was some disturbance of the ground under the nozzle, but it was a blast as in a blast of air.

You can also use very basic math to show why you wouldn’t expect one: If you use the specifications, you can show that the pressure under the engine was only about half a pound per square inch. The average adult when walking exerts about three times that pressure. When you clap your hands together, you exert more pressure than the lunar module’s engines did on the surface of the Moon.

If astronauts did land, there should have been a large amount of dust floating around, yet we can see no sign of dust on the space suits or their surroundings.

There actually shouldn’t have been. This is a case where your every-day experience on Earth does not prepare you for what to expect on the Moon. If I take dust and blow on it in this room, it billows out and slowly falls down after swirling around for a long time.

But, there’s no air on the Moon. Any particle that’s kicked up will go up and then drop right back down. There’s no air to suspend the dust. In fact, you can go to movies of the lunar rover and see it kick up dust and fall right back down to the surface which requires the vacuum of the Moon rather than an air-filled sound stage on Earth.

6. About the “identical background” claims on Apollo 16 mission footage, how do you dispel this claim? Some people (such as Phil Plait) have said that it’s just a simple error with the video. They say that Erick Jones, who is the editor of the Apollo Lunar Surface Journal, says that those two clips were taken about only a few mins apart. According to our research, the “identical background” video clips were taken from the NASA-sponsored documentary video, “Nothing so Hidden.” And the documentary is produced by other production company outside of NASA. Therefore, our understanding is that it’s an error on editing stage of production: the production company took wrong clips and audio and used in the documentary. What do you think of our theory?

Makes sense. This is an innate problem with conspiracies: You have to suppose this vast maniacal group of people trying to hide the truth, so you can’t trust them on anything. And yet, this claim requires you to trust an original claim that was shown to be in err and not trust the correction.

There was a lot of footage taken on the Moon, a lot of audio and video. Stuff gets mislabeled, put in the wrong box, or edited wrong in production of documentaries afterward. Despite all attempts, the people involved were only human, and mistakes are bound to happen. You shouldn’t contribute to a conspiracy what simple human error can very easily explain.

-How did NASA usually archive footage back then during the Apollo project

[Explanation courtesy of "Expat" of the Dork Mission blog, who worked with the BBC during the Apollo era on the Apollo missions.]

Everything was transferred to 16mm film, by the kinescope process. A contractor, The AV Corporation of Seabrook (just a few miles from JSC, or MSFC as it was then known) handled all media requests. They had a pretty good catalog. No doubt there were also copies for internal use. By the time I made a documentary about Skylab, AVCorp was out of the picture and NASA’s own film editors worked with me to search the archive.

If mastering on film seems illogical by today’s standards, it wasn’t back then. The point is that film is independent of TV line standards. In those days transcoding between the US and European standards was a highly imperfect process. All our documentaries were produced on film anyway, so a video release would just have been a nuisance for us and the end result would have been degraded.

As late as 1981, when I was location producer for the BBC coverage of STS-1, I had BBC engineers getting on my case and refusing to transmit images shot by a US-based ENG (video) crew. We had to go through a ridiculous pantomime pretending that it was a film crew instead. By the time we sent the material back to London via satellite, how could they tell?

-For what purpose did NASA produce these documentary videos of the Apollo project?

A better question would be, why wouldn’t they? Practically every government agency has a public relations department, tasked with disseminating their work to the public and gathering support and more funding. In addition, Apollo returned a lot of useful science that we’re still using today – including myself in my own research – but it was also a world-wide public relations endeavor to prove that the United States was better than the Soviets. Of course you’re going to make documentaries and put out material to make people aware of it and such a triumph of human engineering.

7. Why do these theories continue to surface even until today? Do you think it’s because we now have easier access to footage from space? Is it a sense of distrust of NASA?

I think there are a lot of reasons. One is of course a distrust of government. Another reason is that people like to think they know secrets, and a conspiracy is a big secret.

Another reason is that a lot of the lines of evidence that people point to for the hoax are not easily explained because they are contrary to our experience on Earth. For example, one claim is that there should have been stars in the sky because the sky is black, so it must have been night like on Earth and at night you can see stars. But, the sky is black because there’s no atmosphere, it was actually daytime, and the cameras were set to properly expose the lunar surface and astronauts for day. You can’t capture photos of stars with those settings. But, the time I just took to explain that was much, much longer than just throwing out the, “there should be stars!” claim and it’s much easier given our every-day experience to think that there should be stars, rather than take the time to understand why there aren’t.

8. Why hasn’t NASA given their opinion on the Apollo moon-landing hoax ever since 2001? (What is the reason NASA doesn’t answer the conspiracy theorists?)

I would guess because they don’t want to give it any more publicity. It’s a lose-lose-lose situation for NASA:

a. If there is no official statement, conspiracy people will point to that and say that NASA won’t even defend themselves.

b. But if there is an official statement, then conspiracy theorists will say that NASA took the time to respond to them so there must be a controversy and they must be hiding something and you can’t trust anything the government says anyway.

c. In addition to that, Congress will wonder why they should be paying NASA to respond to ridiculous claims, and so NASA risks having their budget cut.

This happened maybe a decade ago when NASA was going to pay James Oberg, an American space journalist and historian, to write a book dispelling the hoax claims. And NASA lost-lost-lost: First, conspiracy people said it was a disinformation campaign; second, Congress wondered why NASA was spending money to do this; and third, when NASA cancelled it because of the outcry on all fronts, the conspiracists claimed NASA cancelled it because it really was a hoax.

Not Related to the Moon Hoax

9. There are still images taken by the Voyager of Saturn that Dr. Norman Bergrun, as author of “Ringmakers of Saturn”, claimed to show a UFO. What do you he possibly mistook it for? This is an example article about Dr. Burgrun’s claim.

Bergrun’s process was to take photos that were published in things like newspapers and magazines, put them under a microscope, and take a photo of them through the microscope’s eyepiece, and then look for weird tings. When going through that process, you are going to find weird things. Every example of a spaceship or alien or whatever that he has can be VERY easily explained by dust or gunk getting in the photo, or uneven illumination, or film grain, and the anomalies he found do not appear in ANY other version of the images.

In fact, one such example that Bergrun points to as a UFO is a bright speck in the bottom of an image, except the bottom part of that image is clearly NOT part of the image that Voyager took because the rings cut-off about 20% of the way from the bottom. This shows that the photo he’s using is a reproduction, including blank area, and he’s pointing to image anomalies caught in that duplication.

- And there are the 1996 infrared photos by the Hubble Space Telescope in 1996 [SJR-- actually, 1995], and some people insist that that is a UFO. What do you think of it? What do you think it possibly is? The refereed photos are shown here.

They look like moons to me. Each exposure was 5 minutes long, and stuff moves in 5 minutes. In fact, one of the outer-most moons that’s within the rings, Atlas, goes around Saturn every 14 hours. In the time that photo with Hubble was taken, it went about 0.6% of its orbit, which would mean it should be a bit elongated. Every moon interior to it would be even longer because they would have moved farther in its orbit in the same amount of time.

10. In addition, there is now footage that NASA releases to the public on their homepage, and this footage or stills sometime show space debris or mini-jets that NASA has captured. Then, some people look at those debris or mini-jets, and introduce them as UFOs on the Internet. Why do you think people often do that?

I think people “want to believe.” They are going to look for any sort of anomaly or object they can’t explain and then say that, because they don’t know what it is, it is aliens. In skepticism, we call this an “Argument from Ignorance” – they are ignorant of what it really is, so they make up what it is in a way that fits their preconceived ideas.

Final Thoughts

The interview was more focused on the origin of the conspiracy and a bit more on general conspiracies than on debunking particular claims made by hoax proponents. I have no idea how I came off on camera – this was my first “real” moving-picture-type interview other than for the Richard Dawkins Foundation for Reason and Science that I did at TAM last year that has yet to be put online (but apparently they ARE working on it!). We’ll see.

They might send me a DVD copy when it comes out. I know my mom wants a copy.

Podcast Episode 11: Dust and Rock Claims of the Apollo Moon Hoax


It seems like I just put out an episode. Which I did. Here’s the second regular episode for the month, another one on the Apollo moon hoax/conspiracy. I’m trying to go through the claims that don’t rely on a bunch of photographic evidence because, obviously, that’s difficult to do during a podcast.

So I picked about a half dozen claims related to the specific category of claims of dust and rock, and I discussed two rock-related independent ways to show that we actually did land and bring back astronauts.

It’s also a bit long, almost 40 minutes. Enjoy.

Podcast Episode 5 Is Up: Heat and Radiation Claims of the Apollo Moon Hoax


Episode 5 of my podcast is now up. The subject is my first for the podcast on the Apollo Moon Hoax mythos. There’s a lot that can be done with it, just like many of these other topics, but this one is more difficult because at least half of the main “evidence” used by conspiracy hypothesists deal with photographic claims. And, as I’m sure most of you know, visuals don’t work too well on an audio podcast.

So, at least for the first several episodes on it, I will be concentrating on claims that can be talked about without referring to a lot of the pictures (crosshairs, stars, shadows, halos, etc.). This one is no exception.

There’s not too much else to say here on the topic other that, on Monday, a very happy occurrence, well, occurred: Frasier Cain, the publisher of Universe Today, posted about my special episode on Comet Elenin. Universe Today (“UT”) is very popular. It is ranked up there in the 13,000s for the most frequented websites in the world. In comparison, my own domain is around 5 million (it was around 6 million a month ago).

Anyway, my webstats update at about 6:30AM PDT. The podcast episode had been up around 60 hours before Frasier posted, and it had 129 downloads. Frasier posted it, and 14 hours later, that episode had 1339 downloads. The next morning, so 38 hours after Frasier posted, it was up to 2938. This morning, we died back down and it was “only” up to 3279 downloads. More telling is that the number of downloads for episode three have jumped by around 250 since Frasier posted. Most telling will be how many downloads I get on this episode because that should indicate new subscribers.

So yes, this is a bit of self-promotion, but it has to do with this podcast and, well, my blog is a bit about self-promotion, isn’t it? I should also note that, as a result of being posted on UT, it’s now listed on Portal to the Universe and just this afternoon I was asked if the ‘cast could be rebroadcast on Astronomy.FM Radio.

So, yeah. If you have ways to help promote my podcast (assuming you like it), please let me know!

The Apollo Moon Hoax: What’s Up with All Those Crosshairs? – Disappearing, Not Centered, and Tilted


Introduction

Within the class of Apollo moon hoax claims of evidence, there’s the giant category of photography and videography. Within that, there is a reasonable chunk of a few claims that deal with the crosshairs – also known as “fiducials.” There are numerous anomalies that deal with these crosshairs, and this post is meant to address most of them.

All posts in this series:

The Claims

There are two main crosshair claims. The first is a favorite of Bart Sibrel, who talks about it in his docudrama, A Funny Thing Happened on the Way to the Moon: “A crosshair, which was burned directly into the image by the film plate, and thus should always appear on top of the objects in the photograph, appears behind the object in this scene, clearly revealing a composite of two pictures into one.” (Note that the specific scene in the movie is shown below.)

Bart Sibrel's "Disappearing Crosshair"

The second claim deals with the positioning and orientation of the crosshairs, with this quote taken from Bennet & Percy in Dark Moon, p. 68: “In some photographs the large crosshair is not centered, and in other the grid is not aligned with the image boundaries.”

What Are the Crosshairs?

Before I actually address these claims, I need to give some background information. The fiducials were etched onto a glass plate, each fiducial having a width of 0.1 mm (100 µm). They were etched in so as to be perpendicular/parallel with the edges of the glass plate. The center crosshair was larger than the others.

This plate was then inserted into the cameras between the lens and the film. Therefore, as the hoax folks claim, the crosshairs should all appear “on top of” anything in the photographs, and they should be aligned with the original image boundaries.

Part of the reason for having these was to determine the distances to objects when taking stereo pairs of images.

Why Do They Appear Behind Objects?

In every single example shown, the fiducials seem to “disappear behind” a bright, white object. There are three reasons why this happens: Bleeding of the emulsion, saturation of the dynamic range, and low-quality reproductions.

Taken in order, because the fiducials were so small, a bleeding of the chemicals to make the image of less than the width of a human hair could easily act to remove the fiducial.

This isn’t a very satisfying answer to today’s crowd of folks who have never developed film in a darkroom, so let’s move onto the second reason: Dynamic Range. This is actually the same reason why you don’t see stars in the photographs from the moon. The idea is that film can only record a certain level of darks to lights.

Let’s say that it’s represented by a number between 0 and 99. That is our dynamic range. Now let’s say that in a scene, we are going to take a photograph that lasts 1/100 second (0.01 sec). In this time, the darkest object in the scene reflects 0 or maybe 1 piece of light. In this amount of time, the brightest object in the scene reflects 150 pieces of light. And then there are objects of intermediate brightness.

When the image is recorded on the film, anything that emits or reflects more than 99 pieces of light in that 0.01 seconds will appear white. 99, 121, or 150 will all appear to be the same brightness.

Now, when we look at the photographs and these crosshairs seem to disappear behind a bright object, that’s in part due to the limited dynamic range. That bright object was reflecting more light than the camera could record in that exposure. And when the crosshair was over it, it did not lower the brightness enough to appear any differently.

This goes hand-in-hand with the third reason: Low-quality reproductions. Anyone who’s ever used a photocopier knows that you want to use the original. If you make a copy of a copy of a copy of a copy of a copy … then you will lose resolution and color-matching with each copy, eventually coming back with a splotchy, muddy image.

Apollo photographs have been copied so many times that the very slight brightness difference that a crosshair over a bright object vs. the bright object itself would have that it can easily disappear.

A side-reason from this is not just due to the copying, but also due to each person who got the copy (and then copied it and passed it on) manipulating the image. Anyone who looks at the image from Sibrel’s movie above (and re-posted below) who has photography background will notice that the image has been overly-sharpened (you can tell by the very bright white line on top of the hills in the background, among other things). When you sharpen an image, you have to select a pixel size overwhich to sharpen. Anything smaller than that pixel size will lose all detail, and hence the very fine lines from the fiducials can, again, easily disappear.

Bart Sibrel's "Disappearing Crosshair"

Why Are the Crosshairs Rotated, and Not Centered?

To revert to an ad hominem, this is a very silly claim, especially in this day and age where 5-year-olds can manipulate photographs on the computer. Remember, this was a massive public relations (PR) campaign, and NASA had to convince the American public (and the world) that this was worth doing.

So while NASA wouldn’t release all the bad photographs that the astronauts had taken, they also would take the good photographs and would crop and rotate them, which obviously would move the crosshairs around.

For example, I like to use Apollo 11 photograph AS11-40-5868, which shows Buzz Aldrin coming out of the lunar module (LM). The original photo is shown below, with the big crosshair centered, and the others all aligned with the image boundaries. (Note that I have sharpened the image in order to bring out the crosshairs.)

Apollo Photograph AS11-40-5868

Apollo Photograph AS11-40-5868

Now, let’s take another look at the photo. It’s kinda neat, but from a photographer’s point of view – and a PR person’s point of view – not all that great. The horizon is crooked, the astronaut looks like he’s going to fall off the ladder, and there’s this clunky machine that looks like it’s tilted and going to fall on him.

So let’s rotate it, and then crop it:

Apollo Photograph AS11-40-5868 After Rotating and Cropping

Apollo Photograph AS11-40-5868 After Rotating and Cropping

There now — we have a flat, horizontal horizon, the astronaut is majestically descending the ladder, and the clunky machinery of the LM is standing there, ready to take him back to the Command Module, orbiting above.

But – gasp! – the crosshairs are now rotated, and the large one is off-center!! Getting an idea for how silly this claim is, yet?

Final Thoughts

The crosshair/fiducial claims are just as much of an anomaly hunt as most of the other “evidence” for the conspiracy theorists. Each claim may, by itself, seem to make perfect sense, but then once you actually examine the claims, you will quickly find that they just fall apart.

The Apollo Moon Hoax: Lunar Reconnaissance Orbiter Images Apollo Landing Sites


Introduction

In my post on “The Apollo Moon Hoax: Why Haven’t Any Pictures Been Taken of the Landing Sites?” I mentioned that NASA’s Lunar Reconnaissance Orbiter (LRO) is scheduled to take photographs of the Apollo landing sites. They did.

All posts in this series:

The Photos

These are really fairly unprocessed photographs and they are not at the highest resolution that they will eventually be once LRO actually targets the sites for close-up imaging during its primary mission phase (the narrow-angle camera should be able to resolve sizes of ~0.5 m (1.5 ft)).

However, they are still pretty darn cool, and they fly in the face of people like Bart Sibrel who in this CNN.com article is quoted as saying: “I do know the moon landings were faked,” said crusading filmmaker Bart Sibrel, whose aggressive interview tactics once provoked Aldrin to punch him in the face. “I’d bet my life on it.” Well, Bart, what do you think of these?

Apollo 11 Landing Site

Apollo 15 Landing Site

Apollo 16 Landing Site

Apollo 17 Landing Site

Apollo 14 Landing Site

I think that it’s so cool that you can actually see the astronaut’s footprints (well, the trail of footprints) on the moon. Amazing. (The visible trail is due to the astronauts disturbing the material on the lunar surface, much like we can see the rover trails on Mars from orbit.)

Final Thoughts – The Likely Hoax Response

As I said before, most of the Apollo moon hoax proponents will likely see it as a publicity stunt, that NASA faked ‘em, used Photoshop, or whatever. I doubt this will turn a true believer in the conspiracy theory into someone who now believes the official story.

But, for those of us who do know that we actually did land on the moon 40 years ago, these photographs are a welcome reminder of the amazing achievements of the Apollo space program, and they may serve to inspire a new generation of scientists.

The Apollo Moon Hoax: All the Photos Are Way Too Good!


Introduction

As part of my continuing series on the Apollo Moon Hoax, I am going to address a fairly common claim of all the Apollo photos being too good to be true. I’ll be writing a related post soon about the related claim dealing with how the astronauts actually took the photos (exposure settings, focusing, aiming, etc.).

All posts in this series:

The Claim

This is a pretty common Apollo moon hoax claim, and it was featured towards the beginning of the 2001 FOX docudrama. The basic premise shown during that TV special where they quote Bill Kaysings: “The pictures that we see that were allegedly taken on the moon are absolutely perfect.”

Another version, this time from Ralph Rene: “All the photographs brought back from the moon are correctly exposed, correctly framed, and crisply in focus. This seems suspicious.”

Is This True?

In a word: No.

What’s humorous about this claim in this this day and age is that it is demonstrably false given a computer, the internet, and less than 5 minutes. You can go to any number of websites that archive all the Apollo photographs and see quite plainly, for yourself, that many of the pictures, in a word, SUCK.

The Project Apollo Image Gallery is one of my favorite. I clicked randomly on the Apollo 12 mission. I clicked on three photos, in a row, selecting the position at random. One was good (AS12-46-6821), one was framed poorly with the horizon going down at around a 20° angle while photographing the astronaut’s butt (AS12-46-6820), and the third showed a lens flare of ghosting around the astronaut (AS12-46-6818).

And then there’s the one I’m showing below, AS12-47-7010. The label on the picture is, “Reflection of astronaut.” Quite, um, interesting, but hardly a “perfect,” “correctly exposed,” “correctly framed,” nor even “crisply in focus” photograph.

Bad Apollo Photograph - AS12-47-7010

Bad Apollo Photograph - AS12-47-7010

Why the Claim?

So that bears the question as to why this claim even exists if it’s so demonstrably wrong? The answer is that it’s really cheap to duplicate images these days (17¢ at Costco!!) or to place them online in a digital archive. But back in the 1960s and ’70s, that was not the case. It was expensive to print up images, and it took quite a bit of time.

Since this entire Apollo program was a massive public relations campaign – not only to the American public but to the rest of the world – NASA only released the best of the photographs. After all, of the literally thousands of photographs from the Apollo missions, it simply does not make sense for a press office to release all of them, rather they would want to control the release and only put out the best ones.

And not only that, but ones that may have been cropped and rotated to make them the best … but that’s an issue to address on a separate hoax proponent claim.

Final Thoughts

This claim is, in my opinion, one of the silliest that’s out there. It may seem like a good one, but literally any amount of effort to look into it will show that it’s simply wrong. This is a case of anomaly hunting where there isn’t even any anomaly.

The Apollo Moon Hoax: Footprints Need Water to Form, Right? And How Hoaxers Argue


Introduction

As part of my continuing series on the Apollo Moon hoax idea, I’m going to address a fairly minor claim that’s made about the astronaut footprints, and whether or not you actually need moist material in order to hold a foot impression.

All posts in this series:

The Claim

The basic claim goes as follows: The soil on the moon looks like its wet or made of plaster or something like that. After all, look at how sharp those footprints and impressions are!

Another version is: “Footprints are the result of weight displacing air or moisture from between particles of dirt, dust, or sand. The astronauts left distinct footprints all over the place.” (Dave Cosnette)

Still another version, this time from Bart Sibrel during a “debate” on the March 20, 2009 episode of Coast to Coast AM (around 10 min 30 sec): “If there’s no moisture on the moon, then how come you can see footprints perfectly? Because when you step in the desert where there’s no moisture in the sand, all you see is a circle. But in the photographs of the footprint on the moon, you see an absolute impression of the, uh, footprint indicating that there is moisture in the soil which means they’re not on the moon.”

What Makes a Footprint or Impression Hold its Shape?

After hearing this claim, the basic question that it raises is how does a material hold its shape? The answer is that there are two main ways.

The first way is that there is a glue-like substance between the individual particles of the material. The obvious choice on Earth is going to be water — water acts like a glue and will help a material hold its shape. An example of this is to take a cup of sand and try to make a pile of it. Measure the angle of the slope of the pile. Now add some water, and make the pile as steep as you can again. The slope will be larger because the water acts like a glue to hold the grains of sand together.

Obviously, this is what moon hoax proponents will have you believe is the only way that a material can hold its shape.

But, there is a second method. That’s when the particles that make up the material themselves are able to interlock, a little like puzzle pieces, and so can maintain their bulk shape. A good example on Earth of this would be a pile of flour able to hold almost any impression you make in it.

Digression – Disingenuine Nature of Bart Sibrel’s Arguments

I am bringing this up because it is an example of the way that hoax proponents argue — namely, in this case, Bart Sibrel. It is an example of how he fails to form a consistent picture, and even contradicts himself in his claims in just over one minute.

Directly following the quote I gave above, a caller into the show replied by effectively stating what I did above, and gave the example of flour:

Caller: If you take flour –

Sibrel: Flour has moisture in it.

Caller: — a very very fine powdered substance, then you step on it with no moisture in it at all, then it’s going to make a footprint.

Sibrel: Flour has moisture in it, you can feel it when you put your hand –

Caller: Of course flour has moisture in it on Earth. But you know you can take other substances that don’t have moisture in them and you can still make a footprint. I mean this –

Sibrel: Like what? Give me an example.

Caller: You can take fine rock dust –

Sibrel: Yeah, but you’re doing that on Earth where there’s moisture everywhere, the moon has never had moisture …

He goes on, but the point is made. Sibrel started out by using an example of sand not holding a footprint (note — sand on Earth). Just over a minute later, he contradicts himself by saying that there’s actually moisture everywhere on Earth … so my question is, then, why doesn’t sand in the desert hold its shape, Bart?

Another quality that this exchange brings to light – and is much more obvious when you actually listen to the audio – is that hoax proponents will advance their claim, and if actually in a live debate, they will interrupt the respondent constantly, and they will place the onus on the responder rather than themselves to come up with more and more examples or reasons why their claim is wrong.

You’ll notice in the above that the caller gave a perfectly fine example of flour, but Sibrel completely dismisses it by asking for “an” example – ignoring that he had just been given an example. Then, when the caller gives a second example, Sibrel goes back, sidesteps the example, and effectively states that any example is no good because it’s on Earth where there’s water. This is a classic example of the “shifting the goal post” logical fallacy.

What’s the Lunar Regolith Like?

First – a note on terminology is that astronomers call the surface of the moon to be made of “regolith,” rather than “soil,” since soil implies an organic (life) origin.

Anyway, the surface material of the moon has been created over the last ~4.5 billion years by meteorite and micrometeorite bombardment. It’s been pulverized. But, it has not been smoothed out due to normal processes of erosion on Earth, such as by wind or water.

Consequently, the lunar regolith is made of, effectively, shards of rock. And microscopic shards of rock are going to be able to interlock just as in the second method I described above. You don’t need moisture to make impressions when you have particles that can interlock.

Why Does the Lunar Surface “Look Wet?”

Apollo "Wet" Surface
A part of this claim that I’ve neglected so far is why the surface actually does look wet in some photographs. The reason is simply that it looks darker. We are evolutionarily trained that when we look at two surfaces and one is darker than the other, we will likely think it looks wet. For example, go to the beach. Wet sand is darker than dry sand — it’s that simple.

The reason that some places on the lunar surface “look wet” is because the material was (a) rougher at a centimeter-size scale (such as where the astronauts were digging or walking around), and since all the Apollo missions took place during morning on the moon when the shadows were very long, a centimeter-scale roughness will cast shadows over the area making the material look dark. An example of this is shown in the photograph on the right.

Final Thoughts

This is yet another example of anomaly hunting in the basis of the claim, and one where the hoax proponents rely yet again on the majority of your experience on Earth (when material looks wet, and why material holds together) in order to propagate their claim.

But, yet again, when you actually examine all the factors involved, the hoax claim evaporates much like water would on the lunar surface.

The Apollo Moon Hoax: Why Is There No Lunar Dust on the Lander’s Footpads?


The Apollo Moon Hoax: Why Is There No Lunar Dust on the Lander’s Footpads?

Introduction

For my continuing series in the Apollo Moon Hoax, I am going to address a claim that follows along the lines of the NASA stagehands not doing their job right — not placing any dust on the lunar module’s footpads.

All posts in this series:

The Claim

The basic claim goes as follows: When looking at the pretty pictures of the golden footpad of the Apollo lunar module (LM — see photo below), there doesn’t appear to be a single grain of dust on it, as though the module was just “placed there.”

Lunar Module Footpad - AS11-40-5926

Lunar Module Footpad - AS11-40-5926

Obviously, the NASA people who didn’t put the dust there were trying to tell future generations that this was a faked event, leaking this information out so no NASA higher-ups would realize.

The Lunar Atmosphere vs. Earth’s Atmosphere

There isn’t any. Simply put, the mass of the entire atmosphere of the moon is less than the amount of gas expelled by each Apollo descent engine.

As a result, if you were to pick up a handful of lunar dust and drop it, it would fall straight down with an acceleration about 1/6th that in Earth’s gravity. It would land directly below where you released it.

But it would appear to fall faster than that when compared with actually dropping flour-like substances on Earth. This is due to Earth’s atmosphere, which adds a resistive force to the dust settling down. In addition to this resistive force preventing its downward motion, Earth’s atmosphere is not still – it moves around. This allows any light material to billow out, creating clouds of material, and rarely landing directly below the location you released it.

The Lunar Module’s Descent Engine Shut-Off

The Apollo LMs had an antenna that when it came into contact with the lunar surface would trigger a light inside the craft. This light would be a signal to the astronauts to shut off the engine. Hence, the engine would be shut off before the craft landed.

Putting the Pieces Together to Debunk the Claim

At this point, we have two facts. First, lunar dust will drop straight down if it is released – be it from an astronaut that picks it up or from the force of a rocket engine’s exhaust (which, while not strong enough to create a crater was strong enough to suspend lunar dust). Second, the Apollo engines were shut off before the craft landed.

Consequently, as soon as the engines shut off, the source of a temporary atmosphere that surrounded the craft was terminated, and the dust that was suspended in it immediately dropped towards the lunar surface. The craft still had both a horizontal component to its trajectory, and the legs were above the majority of any of the temporary atmosphere that suspended the dust.

Hence, when the craft landed, it landed both to the side of the settled dust, and the dust would have already settled before the craft touched down, preventing any from being deposited on the LM’s footpads.

Final Thoughts

This claim is yet another one that hinges upon a perceived anomaly. And yet, this anomaly is common sense here on Earth but our common sense does not serve us well when trying to understand the lunar environment. When you hear a hoax claim, try to think about what would really happen in the environment of the moon, and you will be on your way to debunking the claim yourself.

The Apollo Moon Hoax: Why Is There No Blast Crater Under the Lunar Module?


Introduction

For my continuing series in the Apollo Moon Hoax, I am going to address a claim that anyone who has taken physics could explain: Why there is no “blast crater” underneath the lunar module’s rocket engine on the moon’s surface.

All posts in this series:

The Claim

The basic claim goes as follows: Before the Apollo landings, real NASA scientists and real artists (as opposed to fake ones) thought that the engine firing may create a blast crater underneath the lunar module. Pictures of the real site, however, showed no such crater, not even a big depression in the surface, as though the module was just “placed there.”

Obviously, the NASA people who didn’t create the crater on the soundstage/set/Area51/whatever were trying to tell future generations that this was a faked event, leaking this information out so no NASA higher-ups would realize.

Let’s Talk About Pressure

In physics, I think almost everyone knows that much discussion is given to studying “forces.” What is a force? A force has units of mass * length / time2. In other words, a force can be thought of as “what it takes” to accelerate a certain mass over a certain distance in a given amount of time. Gravity is a force. A human stepping exerts a force. A rocket engine exerts a force.

Moving one step further in complexity, we get pressure. Pressure is force / area (mass / (length * time2) ). So while a human stepping exerts a force, when you divide that force into the area of a human footstep, you get a pressure exerted.

The concept of force is actually shown in a neat magic trick that my parents would never let me do as a child: Take a coin, such as a dime. Take a nail and a hammer. Try to hammer the nail into the dime. You probably won’t be able to. Now take a pin and try to hammer the pin into the dime. It will likely go in. Why? Because while you are exerting the same force through the hammer, it is concentrated over a much smaller area with the pin, and hence you are exerting a greater pressure.

Another way to think about that is to take your finger and push on your forehead. All you may get is a white mark for a bit before the blood returns. Now, think (don’t do!!) about what would happen if you took a pin and tried the same thing. You would puncture the skin because while you exert the same force, you are exerting a much greater pressure through the pin.

How Is Pressure Relevant? — The Crux of Debunking This Claim

First, some numbers: The lunar module (LM) descent stage engine had a maximum thrust of 9870 ft-lb, but this was throttleable back to a minimum of 1050 ft-lb. Sounds like a lot. But, the diameter of the nozzle was 63 inches, which is an area of about 3120 in2. Dividing this into the force (thrust) and you have a pressure range of 0.4-3.2 ft-lb/in2, otherwise known as psi. This is equivalent to the metric 2760-22,100 N/m2. But let’s stick with psi.

Anyone who owns a car probably knows that this is already significantly less than your tire pressure … by a factor of 10-100. When Apollo 11 landed, the thrust was down to about 1/3 of max, so down to around 1 psi.

Now let’s look at the average adult footstep: The average non-American weighs around 150 lbs. The average human footprint is around 50 in2 (don’t believe me? do the math yourself!). Divide the first into the second and you have the average human footstep exerting a simple 3 psi.

This is 3x larger than Apollo’s engines!!

The very fact that the astronauts walking on the moon did not create “blast craters” underneath them should be explanation enough as to why the engine did not create a blast crater under it — the pressure was simply too low.

Then Why Did They Think It Would Before?

Good question. The best explanation that I could find is that when the hoax believers say, “NASA scientists,” it implies all NASA scientists. But it could just as well mean 2 NASA scientists as 2000. Hence, I would hypothesize that this was a possibility that was raised by a few people, but the majority in the review board said it would not happen and so the missions went ahead.

As for the artist renderings, well, many of the pictures painted at the time also show a big yellow-red flame coming out of the rocket engine as the LM touches down. But – as was known by all NASA engineers who knew about the fuel system – the fuel used would create no visible exhaust “flame” while in the lunar environment. Hence, an artist rendering should be taken as just that – an artist rendering and not as a scientific gospel.

Final Thoughts

Well, this is actually one of my shorter posts, but I’m trying to be less verbose these days as some feedback I’ve gotten is that I type too much. Regardless of that, though, I think that I’ve covered this claim reasonably well. All because some people thought one thing prior to Apollo landing does not mean that Apollo finding something else is evidence of a hoax. That’s what scientific exploration is.
