Two things have always fascinated me... space exploration (not just sci-fi, but the real stuff), and submarines. Anything with a submarine on TV, and I was hooked.
I love the moon though, even though it is bleak and barren compared to many of the other heavenly objects you see on NASA's pics of the day. There is just something forlorn, brooding, lonely and incomprehensible about it. I just identify with the moon... sorry, getting a little carried away here.
Great pic, I used to have the "famous" earth pic as my start up screen on my very old mac
Woof, Woof Dawg
