The third pass over Cydonia obviously missed the stated target, which was the odd structure with the triangular enclosed space.  Nonetheless, they seem to have snapped a fairly good photo of one of the pyramids which is still sufficiently intact that there is no possible question as to what it is.  Every once in a while, a sufficiently good screw-up is all you need.  The entire NASA image strips may be seen at:

More rational treatments of the new image of the face monument than much of what has been heard may be viewed at:

The significant part of the 4/23 NASA image of the main city pyramid, unmodified other than for NASA's own MIPL enhancement, looks like:

To me at least, the pyramid is four sided and the four triangular sides are clear enough, and I've marked them with green lines.  The other part of the image which I believe I'm seeing amounts to some sort of an enclosed corridor or causeway leading out from one corner of the pyramid, and then two funny and nearly rectangular features at the end of that causeway or whatever it is, which may be doors or some sort of adjunct buildings or something.  There also seems to be a line going from the Eastern corner of the pyramid to the two doors or whatever, which I've marked with a blue line, but I suspect that's just an edge of sand being blown up into a sort of an apron abutting the pyramid, and that the hollow between the pyramid and the corridor would naturally trap sand.  In particular, if you didn't look at the whole thing closely enough, the line (blue) from the Eastern corner to the two doors might cause you to think that the whole structure was irregular enough to be a natural formation but, again, a closer look seems to me to forbid that.

Again, my  take on all of this is that you don't build something like Cydonia with spacesuits on.  The planet has to be habitable for something like that complex to get built, and the only cosmology I know of which would allow for Mars ever having been habitable is that of Alfred DeGrazia and Earl Milton, and that can be found over at:
