Mars Light

The Curiosity rover took pictures on consecutive days of a bright light on the distant Martian surface.  NASA says it was sunlight glinting off a rock, or perhaps sunlight entering the camera at just the right angle.  UFO researchers are saying it's something else.

We know what Mars is like now, however.  There is no civilization on the surface.  UFOlogists will  have to do much better than this to make their case.
