This is object is flying and is a great distance away from the rover. This is one of the most recent Curiosity rover photos to date. Found by Streetcap1, this object is 100% evidence of UFOs flying about over the Mars surface.

Streetcar1 of Youtube states:
This object is upright, not a blob, looks structured even from a distance and only appears on one frame. Hard to dismiss it as a grain of sand which jumped up on the camera lens, then jumped off again. Streetcap1.
