Re: light and dark gray
Thanks, Phil,
Here's the famous picture of Taurus Littrow taken from orbit; just like in the previous picture, we notice the striking difference in gray between the mountains (South Massif-light gray)and the floor (dark gray-like the Maria).
In the book (which is on the net) Apollo expeditions to the Moon, there is a pic of the LM taken from orbit.
