The lights could just be because of a different light inclination from the sun, although the symmetry still is curious.

The entrances I don't know what to say about. I notice some strange colouration around the second one, anyone have an idea what caused that? The first one seems to be at the edge of two images transitioning, I'd be curious to see what it looks like with the same detail level over the whole area.

The scale and resolution in these pictures leaves for a lot of wiggle room.

Also what is the scale for mars and what is the scale for the moon, the size of these features could be hugely different.

I would think that if there were some secret base, they would do a better job of hiding it. then again, you look at how well they do everything else lol.

I thought the same thing. But the lights on the moon is hard to dismiss.
