Greetings, Here is a mystery that has puzzled me for many years. Perhaps one of you can enlighten me, and the rest of the list.
At the height of the US space program, the National Geographic published a photo of someone on the moon. In the photo was a tripod-mounted device which the caption described as a gnomon to determine the orientation of the photo. I guess that it cast a shadow, and the clever bees at NASA then analysed this against sun angle or whatever, to determine the orientation of the photo. I tried many times to get more information from NASA, but met a blank wall every time. They simply weren't interested in looking in their archives. I sent them a xerox of the photo, but got nothing from them. Does anyone know of the photo? Or, more importantly of the device? Where are plans for it? etc. As I am far from my office and home, I can't retrieve my copy of the National Geographic article easily, but it would be of great interest to diallers. I have never seen any other reference to it.
