On the main blog we have been given an entry into the NASA Flickr Photostream

along with a link to PetaPixels file of spacewalks with Nikons

Great stuff, and if any comments need to be made, my observation is the body used currently is a D2Xs, 12 MP, DX. Says something to me about just how many pixels do I need..... humbling.
Some very nice memories for those of us who remember some of the early history of NASA. I was sitting in a college mathematics class when the Mercury Freedom 7 went up on May 5, 1961 with Alan Shepard on board.
