ESA gives Cydonia a new perspective

There's good news and bad news. The good news is that the west side mouth looks better, and even has a little upward turn in it, and the west eye still looks the same. The bad news is that between this view and the one Zip Monster posted, there really doesn't appear to be any nose. Not in the usual sense, anyway. Unless of course, Martian's have noses in their foreheads.
Also, if you look at what's supposed to be the east side mouth, in the view Zip posted, it's not very convincing.

I just looked at this. It's in a feature article on the ESA main web site. These are both low-res composites which are great for posting, but it would be nice to see the hi-res originals that went into making up the composites. For example that bump on the forehead was never evident in any of the previous images, and there is as yet no hi-res MOLA imaging of the face, so far as I know.

Tom mentioned that the other day. The resolution isn't that good that you could get enough data points. And as far as seeing it before in any other image, I don't think they ever got this angle view before.
You're not suggesting that the bump is a mistake, and not really there, are you? I like the "nose in the forehead" theory better. Remember the Star Trek movie where Kirk kicks that big alien in the knee, and he screams like he just got kicked in the groin? Well, he did.
From the ESA description:
"The image shows a remnant massif thought to have formed via landslides and an early form of debris apron formation. The massif is characterized by a western wall that has moved downslope as a coherent mass."
So, that's what they think happened. I never saw that before.

<br />it would be nice to see the hi-res originals that went into making up the composites.<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">There are no "hi-res originals". Mars Express has limited resoution compared to MGS. The originals are all available, but each shows less detail than we are accustomed to seeing, and the composite has simply blurred many features by averaging many different views. One such original is shown below.
The only real advantage is the addition of color. There really is a hint of blue in the west eye, something quite unexpected for natural terrain.
More importantly, some of the previous images were up-side-down compared with our usual views. So comments about various features may need to be rethought. -|Tom|-

Partially incorrect. One could repeat JP's method to get hi-res MOLA data for the face. NASA has data from each pass of the spacecraft. With the help of an IT collegue, JP compiled MOLA data of reasonably high resolution for the Profile Image (and concluded it was flat but with a slight slope in keeping with the lay of the land.) It's in his paper on the subject. (Sorry I don't have the link with me).

For example, we cannot measure the height of the nose ridge or the depth of the eye socket because the beam is so wide that the data can give only the average range to each of those areaa. -|Tom|-
