Misha, I pulled up the press conference (http://www.youtube.com/watch?v=BI_ZehPOMwI
). It's an hour and a half so I didn't watch the whole thing, just jumped around a bit. I don't see them as morose, serious yes, but there were a few jokes certainly and some self deprecating humour as well by the guy about his driving and doing three things at once. I might go through the whole thing over the weekend, but if those guys are actors, they are pretty good ones!
Another question on the video and photo analysis: there's been a lot of talk about light sources and shadows and calculations, etc. Is there reason to believe that light behaves exactly the same on the moon as it does on earth? With different atmospheres would there perhaps be different calculations necessary? I don't know the answer. Anyone know if this question has been addressed?
