I posted a thread while ago about some smudges on some NASA Spirit photos that I was convinced were airbrushed and tampered with.
Turns out they weren't, but when analyzing what caused the "image artifacts" I discovered something that is pretty cool and I would like to share.
Let us discuss, because that's the point of ATS and I get so irritated by the "nothing to see here's". There is always something to see.
The smudges in question were caused by a highly reflective light source. That much I can say for certain, beyond that you decide.
There are two anomalies in question. They were first imaged on Sol 1352
It was pointed out in the other thread that these were processing errors in the images.
Either way, NASA was intrigued and on Sol 1354 the same two objects were imaged again using the L7 and R1 filters.
I have combined the following image using two from Spirit and labeled the anomalies.
The Panoramic camera on Spirit is equipped with many filters see here...
Sol 1356 - Spirit imaged each of the objects using the L2, L5, and L7 filters.
A false color composite is shown below for each.
Granted the RGB images were composited from other images that all had the "image artifact", so there is information loss, but still there is some
detail to be seen.
And NASA must still be interested because here we go.
Sol 1361- Spirit images each anomaly again, this time using its full complement of Pancam filters. L2-L7 and R1-R7, thirteen different filters.
These are false color composites of each using the L4, L5, and L6 images.
Every picture taken of these two objects produced the same "image effect", except for one.
This image was taken using the L7 filter. It is the only image of either object imaged by Spirit that isn't affected by the "image artifacts", and
there is a considerable amount of detail to be gleaned.
So what say you ATS? Cosmic Cube or shiny rock?
