"On July 20, 1969 the first man stepped on the moon. During the next three years, six missions to the moon were made and a total of twelve astronauts walked on the moon. During these missions thousands of images were taken, most of them with the "Hasselblad EDC", a special version of the Hasselblad 500 EL."
There are also tons of amazing images available from all of these mission at the Project Apollo Image Gallery. Here's a selection from the Apollo 11 mission.

I heard that they only brought the film backs home to save on the weight. You know what that means! Free Hasselblads for anyone willing to go and pick them up.
Great pictures! I used to have prints of some of them as a kid, send to me from NASA.
Great post - I particularly liked the link to the gallery of space cameras. Until recently, I always thought that Hasselblads were the only cameras taken into space. But at a recent exhibit of spacecruft, I saw a photo of an astronaut with a rangefinder that my Flickr friends identified as a Zeiss Contarex Special. See the photo of the photo here: http://www.flickr.com/photos/stevehopson/932160964/in/set-72157594220045098
If you want the hasselblad you have to goto the prop room where they left them on the set.
These images are stunning!!
If you were around in July 1969, and you want to share - and see comments by others - we set up a special POST on Apollo 11 at Blog on the Universe, with resources and links.
