QUOTE (Phil Stooke @ May 8 2012, 03:03 PM) *
But I would take issue with you on one point. At Apollo 15 you say there is no clear evidence of a flag shadow, and that is true in the first frames, but not in the last three where a very dark shadow appears and moves as expected. Maybe the orientation of the flag is such that the early frames are casting a very thin shadow (i.e. the sun is in the plane of the flag in the mid-morning).


Thanks, Phil.

Yes, I, of course, noticed those frames too during my work on this. My original assessment was that more work was needed (since it was not so clear cut as the three I was sure about) and I couldn't understand the shadows being shown without more modeling/analysis. Eric Jones and I went back and forth about this a lot. If someone in the audience wants to offer a model (i.e. 3D) for the shadow casting for these frames, then we would welcome it. It is baffling. You idea might work but I have not had the time to test it and other theories.

New goodies keep turning up on the Moon. Another quasi-Ina structure in Mare Tranquillitatis.
