This was found by Streetcap1 of Youtube and shows a thin disk-like elongated craft with a flat back end. Now some people will say thats one of the moon Phobos or Deimos. Well if thats true, then its a not even a freaking moon! Look at the photo above at the detail. It has a ridge around the UFO. It has a flat back with two right angles. It has a curved of the back that meet at its corners. Also the ship is not moving. It looks like its hovering over the rover for awhile and NASA noticed it and took a photo.
Let me put photos of Phobos and Deimos here for you to compare shapes.
The whole UFO is matching on left and its right. That chance of this being a mistake...zero chance. This is 100% guaranteed alien technology. Streetcap1 is hot this week. There's no stopping him. He is a warrior among UFO researchers.

Sometimes the Mast Camera points upward and usually we just see stars.
