I believe you are telling the truth about these images but another truth is that NASA has become more adept at spotting and masking anomalies. I have looked at all these images for an hour or more and dont see any smoking guns. Some of the ones you pointed out are interesting and some have been smeared a bit too. I am afraid we will have to be vigilant and wait until they make mistakes to ID more artifacts.
Look at the left hand and do not notice what the right hand is doing.
I cannot help feeling NASA are trying to take away our attention onto something else. Focus is on the rock which has been cleaned and ground by the RAT tool but I feel there is much more going on around the outside of these photos.
Top left is a rock which looks like a head with 2 eyes, however I dont think it IS that. There seems to be a raised refief on the top of it consisting of circles etc, maybe a carving, maybe something alien, maybe pipes? Diectly opposite that on the right hand side at the same level in the photo is another rock with a raised relief 'twig/stick' like thing on the top right of it. I think the front of that rock has been blacked out so we dont look at it too much.Maybe something under there too 'cos the shadow is strange.
Various other bits and pieces dotted around. NASA has taken 10 different images of this scene using almost every filter they have. This number of photographs is very rare so there must be something worth imaging (each image vcosts a lot in terms of money and time to download) and it is obviously NOT the RAT rock we are supposed to believe is the focus of attention.
If you want to scientifically examine the RAT rock, then why not take close-ups of it? Bearing in mind they have much, much better quality photos than we are given, I think there is something else here we need to identify.
