Great picture! I really like that velvet-like blackness that surrounds Aldrin and the light being cast down on him.
Man, I wonder if one of the thoughts they had while walking around on the moon, especially when looking back on Earth, was if they were ever going to get back. That would have had to been one of the scariest prospects that any man ever had to face.
Aldrin and the others were among the bravest of their time.
