Look for your self...
Mare Insularum, zoom in and you will see a crater named Reinhold, right of that you will find a long section that has been smudged out or covered by a dark box to be "cencored" ...strange? Look at it. Now if you ask your self why, you need to check out a documentry named "Moon rising" and it will help you understand the "why."
