LIGHTS AND SHADOWS: MARS

I had reason to re-examine the whole face on Mars story and the images of 1976 and the more recent ones that look so different.  At the same time, I was looking at maps of the surface of Mars I was intrigued by the fact that some shadows seemed to have slightly different slants to them. This might be explained by the overlapping of layers of photographic scans taken at different times. It is an interesting point and it was difficult to find a source that explained the process of stellar cartography to the point that how maps of Mars are created is explained in detail.

Playing with the older image I wondered how it would look if the two halves were placed together. The resulting image was interesting. If  you mirror the one side the end result seems to suggest a long haired dog; so those who claim DOG is GOD spelled backwards may have been close...

The 1970's image

In 2001 a close flyby with a better grade of camera produced this shot:
