Welding the Solar Eclipse

Since the Moon is constantly rotating on its own axis, there is no area of the planetoid which is in permanent darkness, and the far side of the Moon is only completely devoid of sunlight during a Full Moon – when the Sun is facing the Moon with the Earth in between.

That was one of those type before thinking moments I had.
If I had thought about it.....
Of course we knew what was everywhere on the surface before we sent Neil Armstrong so it must rotate and show its back side sometimes.
Just like some people. (Humor)
