The agency said this has happened previously on other cameras on Curiosity and other Mars rovers when the geometry of the incoming sunlight relative to the camera is precisely aligned. NASA also revealed that such glitches are commonplace. “Among the thousands of images received from Curiosity, ones with bright spots show up nearly every week.” Curiosity takes images using two cameras, one in its right eye and the other in its left. While the image from the right eye shows this bright spot, the same image from the left eye does not.
