On the side facing the crater.
Notice also, the Milky Way and stars are visible in the sky.
Can see the stars in many of these images. You don't get that with lunar shots.
What is the straight white line along near the top of the crater wall?
There is also another crater with bright areas, but on the walls in this one.
Did you see how bright the bright spots are in the first NASA animation?
Here, I captured it.
I let it auto play a couple more videos, and it came to a narrated animation. When it came to Ahuna Mons the NASA narrator says, "It isn't a crater, or even obviously associated with one".
It appears very obviously associated with the crater it meets exactly edge on,
and which at a glance, looks very near proportional in size to the Mons.
