More on the Cydonian “Face”

At least one of the readers of this blog indicated an interest for more information on the Face of Cydonia, so here goes. The Face was first noticed in July, 1976, and was considered a trick of lighting. However, two computer engineers Vincent DiPietro and Gregory Molenaar, contracted to the NASA Goddard Flight Centre, processed images using new software, and included a pyramid, about 800 meters high, about 16 km from the Face, in their study. They concluded the Face and the pyramid were hard to reconcile with naturally-formed objects. In 1988, Mark Carlotto further processed the Viking images, and from an analysis of the shadows in the two Viking images, he came up with a three-dimensional reconstruction. Further, he argued that The Face looked like a face from any viewed direction, which does not usually happen with “accidental faces”. He went even further and suggested a second eye socket may be present, and he argued there was fine structure in the mouth suggesting teeth.

The problem with the processing of images is that the processing software invariably contains a bias. The procedure usually looks for contrasts, and enhances strong signal regions and deletes low intensity, but this tends to find things that are not there, or lose things that are. A classic example I can recall came from the “famous” UFO off Kaikoura in New Zealand. A reporter and a cameraman hired an aircraft and took images of an orange light that followed the aircraft. Image-processing software was used. Each run deleted pixels, but no sharpening occurred, so the image was rerun. Finally, all the pixels were removed and the conclusion: there was nothing there! This conclusion is obviously ludicrous, but it illustrates the fact that computer processing merely changes things. In many cases the changes will improve things, but they can make matters worse by leading to a totally incorrect conclusion.

As noted in the previous post, the basic problem was insufficient data. The Viking cameras simply did not have the necessary resolution, mainly because the task they had did not require it. Remember, resolution comes with a price, such as a corresponding reduction in area covered. The reason we only got two images of this zone was that the cameras only imaged this area twice. Mars might be a small planet, but it is a planet, and it takes a lot of thin strips to get the lot. The thinner the strips, the longer the satellite will take to cover everything.

As you might expect, the initial speculations on the Face died down. Most scientists simply shrugged and said, “insufficient data”, while some merely scoffed at the concept. The Face would probably have died a natural death until Richard Hoagland got involved. He pointed out the presence of a rectilinear arrangement of massive structures, together with several smaller pyramids, which he named “The City”. All of this was published in a book, The Monuments of Mars.

Eventually, Global Surveyor produced the image I showed last post, and that should have been the end of it, right? Wrong! If you search the web, you will see items arguing that statistically the chances of the Face being natural are billions to one against. Of course you do not see the details of the calculation. Another interesting point is that Cydonia is littered with mesas like the Face, and these are of interest to planetary geologists because they are in a transition zone between cratered highlands to the south and smoother lowland plains to the north. An argument can be made that the northern plains are the remains of an ancient Martian ocean, in which case the mesas might represent ancient islands. This interpretation is consistent with the erosion around their bases, so the Face might be of interest as providing evidence of such ancient water, if not aliens. In my novel, A Face on Cydonia, I describe an easier means of climbing to the top of the Mesa. I cannot help it if you do not believe this, but I did this from the Global Surveyor images when I wrote it, back in the late 1990s. While rechecking the web, I found a link to a “trail map”, where a NASA scientist indicated where he would climb it. What pleased me is we start in exactly the same place. I am not totally illiterate with images! The link is

Another interesting link  shows some illusions:

One final comment. It is obvious that the shape of the butte is either natural or of alien origin, right? Not so fast! In my novel, A Face on Cydonia I try out yet another option. I also promised a link, so:

Suppose the Face were real and alien, the fringe seems to argue that NASA is covering it up. This must go down as utterly ridiculous. If the Face were a real alien monument and demonstrably so, NASA’s budget would fly upwards! And please do not tell me that NASA is not interested in increasing its budget.

The “Face” of Mars

I start my new SciFi ebook, A Face on Cydonia, as follows:

On the Cydonian region of Mars there are two faces staring into space. Both are two and a half kilometers long, a kilometer wide and about four hundred meters high, and since both are in exactly the same place, no observer can see more than one of them. Most see a battered butte with craters roughly in the right place such that, with considerable imagination, the image of a badly torn face can perhaps be seen. Some, however, see a refinement of the enhancement produced from the original low resolution Viking photographs, a truly alien monument, a deep message to humanity . . .

I refer, of course, to the “Face”, which has gained a certain degree of notoriety as people speculated as to what might have created what we see.  Guesses run from Martians, aliens, to natural erosion. Most people would be skeptical and point out that, “You can see faces anywhere, such as clouds,” and dismiss anything other than nature as nonsense. While this face is somewhat different from cloud faces, it has one interesting thing in common: much of the face is hidden in the original image, simply because the angle of the sun shades half of it. One purpose in my novels is to try to show that reality should follow the rules of logic. So, what would logic say? The first question a scientist asks is, are the data suitable to resolve anything? If they were collected for some other purpose, they may not be. The initial data were collected by the Viking orbiter, which had the task of creating the first map of Mars. The map, perforce, had to deal with the major features, so for various reasons it settled on resolution that would give the desired map. Below, see one of the images of the Cydonia Mensae, in which the Face was first seen. Note that the angle of the sunlight shades quite a bit of the Face.

We can expand and enhance the particular region (small black dots are lost pixels and are not real):

The initial argument against erosion/adventitious craters was initially, the probability of sufficient coincidences is too low. That argument is false, because what was overlooked was that with so few pixels devoted to the face, coupled with the shading, you do not need much in the way of accidental coincidence. That does not prove it is natural, but rather suggests you need better data before reaching a conclusion.

As I noted in Red Gold, we can immediately eliminate Martians, because the face looks like ours  (if it looks like a face) rather than like a possible Martian’s, and leaving aside the inhospitality of Mars, even had there been such Martians, they would have no idea what our face would look like. There are further reasons: there is no reason why a Martian would carve a face only we could see, and Mars could never have evolved indigenous technological life forms without leaving some evidence of the process. Aliens are slightly more difficult to eliminate by logic. As one of the characters in Red Gold said as a joke, space-traveling aliens who visited Earth, say two million years ago, could have worked out what our faces would look like when we evolved sufficiently to develop the technology to see such a butte on Mars, and they could have carved something. It could then be a message to us, meaning, “Come to space; it is possible and it is worth it.” That still leaves the issue of why would they bother to do that.

All of this speculation almost certainly annoyed NASA considerably. Beside the Face, some thought they saw pyramids. That is not hard to understand, except again the specific lighting in the first picture greatly enhances the possibility, since only a pointed top and an edge is required. Accordingly, when Global Surveyor was sent to Mars, NASA promised to use its better resolution to settle for once and for all what this rock was. Meanwhile, I had thought that all the activity might make it worth while to write  a SCiFi novel about the rock. Of course you cannot simply write about a rock, so I had to construct a story around it. This was slower than I thought, and Global Surveyor settled this issue, one of its images being reproduced below:

The end of speculation about aliens! Well, not necessarily in fiction! (Actually, not necessarily in reality, as can be seen if you check the web!) I started my novel A Face on Cydonia with a television program that showed the image of the butte, intending to show how silly people were to think there could have been aliens, when the image morphed into the Viking-type image and winked. Eventually, this lead to an expedition, in which the members all have problems with each of the other members, and the book focuses on these problems. To add to the mix, there are at least three attempts from an external agent to murder at least one of them. Then, to keep the story going, each of the participants finds exactly what they did not want to find, and I set up a situation for more story by having each of them look forward to a future where they will have to carry out what they do not wish to do.

For those interested, in next post I shall give a link to A Face on Cydonia.
