ESA gives Cydonia a new perspective

<br />Other than that, I think this composite is doctored and exaggerated in the extreme—for public consumption and confusion. The hollows are much too hollow, and the huge bump on the forehead is not evident in any of the other images where you could detect such a feature from the shadows cast--and you can't.......But I hope they're telling the truth about the blue eye.--Neil<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">
I just looked through a bunch of Face images, and I don't see any shadows that prove that statement. Can you demonstrate a case where there is a shadow from something else, but not for the forehead nose?

In the original Viking image the forehead nose would be lost in the bigger shadow that covers the whole south east side:



Also, if it was doctored, why would they put a blue eye there?? (not that I see the blue eye, anyway).

Re: MOLA imaging of the Cydonia Face: I don't want to quote from the Levasseur paper, "Profile in MGS MOC M0305549 & E0501429," without permission. But essentially individual orbit measurements were plotted of the Mars Orbiter Laser Altimeter (MOLA) data. Of interest were orbits that passed either directly over the target area or averaged from orbits passing over the vicinity. The upshot is that by this method (if it would be as successful as in the experiment using it for the PI, meaning essentially that at least one orbit would have had to pass directly over the face and record its altitude measurements) the researcher might then be able to tell that the Cydonia face was a mound, and get a fairly accurate measurement of its height. But one could not discern individual bumps and valleys on the face.

I'll post two. This is quite elementary and I haven't much time. In the 1998 image we can see the light coming from the east. There is a bright area on the nose bridge, and in the left (west) eye socket, but just above it (on the lower forehead) where the "bump" would be, we see a uniform gray indicating relative flatness.



In E170104 light is coming from the west and again we see a uniform bright area across the area where the bump would be. If there was a bump you would see it plainly enough in both these images. Moreover, if there was a pronounced hollow in the left cheek area, we would see that plainly enough in the shading also. There isn't.

I don't see any significant shadows in either of them, so I don't see how we could be sure there is one missing. In the Viking image there is a significant shadow, and the forehead nose would be lost in it, I would think.

Here are two more images of the face we can use in an effort to search for an anomolous "bump" on the forehead area, and judging from the shading there is no indication.

E0300824, the famous 2001 image.



Composite of E2001532 and E1501347, the two highest resolution images of the Cydonia face to date. In making the composite for posting we lose resolution, but the variation in lighting adds more perspective.

Here's an example of how shading is used to indicate shape. Realistic art is said to be an "immitation of life." for more examples see link.
