https://flic.kr/p/s6GPpkThey clearly demonstrate the phenomena known as libration (note the small foreshortened mare at the 1'o clock position is further onto the visible lunar surface on the 26th). Libration is caused by the Moon's orbit around the Earth not being exactly circular (it's an ellipse) which means we can see more than 50% of its surface as we can see "around the side" from time to time. It also proves that the Moon is a sphere. I didn't need NASA to tell me anything or to look up anything. My own observations, my own interpretation.
Still waiting for the explanation on how libration works if the Moon is a flat disc as mentioned several pages ago.
*composite = lots of smaller images stitched together to make one large image, like a panorama image, a standard technique and I suspect this is what NASA means by composite to get a full disc image of the Earth from space in some circumstances.
