In the late 1960s, NATIONAL GEOGRAPHIC magazine featured articles about the moon and some excellent photos taken by Lunar Orbiters. One such photo of Crater Tycho appeared in the February 1969 issue, page 234/235. When I studied the crater's central peak with magnifying glasses something stood out like a sore thumb. I took digital phots of the photo in NATIONAL GEOGRAPHIC and they appear below. The first photo is of almost the whole crater and the second photo is a closeup of the central peak area. If you have this issue, you can see the photo in much higher detail than I have reproduced. But the closeup below shows two "symbols" that seem to be leaning against the central peak. The one on the left has a triangular shape towards the top and the one next to it looks like an oval supported by a rectangular base. But the most interesting feature here is the almost perfect Roman V on the ground in front of these two "symbols." Again, the photo is not as sharp as the actual photo but it should whet your appetite to find this issue of NG and see for yourself. I had to lower the resolution of the photos in order to get them both on this post. I finally learned how!
