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.
