So many images, especially the Mastcam, has frenzed creatures all desperately tryimg to get at same food. The problems that occured when mars lost it's atmosphere in extreme antiquity!
The "KNIFE" seems to be repeated in another image! i find that very striking indeed 1
Please notice the similarity in both knives! You need to ZOOM in for clarity of text and image!
The analysis I use for the photos and imagery are not mean't to be exacting, only to get you closer to understanding that there is intelligent life on mars (martians). Many of the rocks you may think are rocks, are in fact highly designed sculptures, mechanical objects etc.
Nasa is trying to leak out anomalous imagery with out of course talking about it public! Though most images have been doctored, Nasa is trying to humbly and quietly nudge us along with out going too public about it vocally. Though it is work and painstaking effort to find objects in the images that have not been altered in some way!
