Great collection of photographs from Apollo 11 over at The Big Picture. I really like the accompanying caption to the above photo:
Astronaut Buzz Aldrin, photographed by Neil Armstrong (visible in reflection). Buzz Aldrin: “As I walked away from the Eagle Lunar Module, Neil said ‘Hold it, Buzz’, so I stopped and turned around, and then he took what has become known as the ‘Visor’ photo. I like this photo because it captures the moment of a solitary human figure against the horizon of the Moon, along with a reflection in my helmet’s visor of our home away from home, the Eagle, and of Neil snapping the photo. Here we were, farther away from the rest of humanity than any two humans had ever ventured. Yet, in another sense, we became inextricably connected to the hundreds of millions watching us more than 240,000 miles away. In this one moment, the world came together in peace for all mankind.”
Always liked this photo for the reflection.
