Possible UFO on Mars in Curiosity Rover Photos

Conspiracy theorist take the possibility that a civilization once lived on the Mars planet, quite serious. Some of the NASA photos taken by the Curiosity and Perseverance Rovers show a glimpse of the Martian world and some of these photos contain something more. In the latest pictures we spotted possible UFO on Mars in the Curiosity Rover Photos. The photos were taken on August 31st by the Front Hazard Avoidance Camera, also called Front Hazcam. The time of the picture is Sol 3224 (2021-08-31 20:26:55 UTC). We believe that NASA knows more than they let us know and these pictures are the proof. You can see the UFO object flying in one of the NASA photos . The credit of these photos goes to NASA/JPL-Caltech.

If you download the image and zoom in on the left corner you will notice a metallic object flying away. The light source seems to be the same as the global image. We are also baffled as to why is the arm of the robot blacked-out. The same object can be seen again if you browse the pictures and reach the next image of the UFO. What do you think about this possible UFO on Mars in Curiosity Rover Photos? Are they real or simple optical illusions?
