First off, great eye OP. I had been marvelling over the quality and detail in the images and was just originally enjoying the pictures for just how
mindblowingly awesome they were. Then your thread came along and I was intrigued
After reading the OP original post and looking at the pictures, I definitely thought they were interesting and the OP did spot something noteworthy. I
then tried to look at it from a mundane explanation point of view and see if there were mechanics involved that could account for what appears to be
As I kept looking though, my first thought was to look at the soil in the background and speculate on had the tire gone through a band of soil
consisting of two colors and could that account for the color variations. Given the angle of the shot, the shadow of Curiosity being cast on the
ground and the relative proximity of both patches of dirt on a color wheel, I didn’t feel I could either support or discount the band of different
colored dirt. I then decided to focus on the “glistening area” instead.
So from what I’m gathering the area inside “box 1” (see image below) is the area of interest from the OP and the area we are focusing on. As I
looked at it, my first impression was could it be a weld seam from the wheel manufacturing that is at the right angle to reflect the light more so
than other spots? The wheel area inside “Box 3” clearly shows the wheel has a pretty high degree of reflectivity associated with it, however the
reflective quality wasn’t quite as “bright” as the area inside “Box 1.” As I was pondering this I noticed the area inside “Box 2” and it
seems right on par with the right amount of reflectivity as is being observed inside “Box 1.” Could this “glistening” area be a product of a
hole in the dust pattern lining up with a particularly reflective part of a weld for the tread?
I’m not trying to discount you, OP I’m just merely offering an alternative hypothesis since really that’s all any of these theories are
