Soviet Moon Images
I happened upon an interesting site that I thought to share. Mental Landscape has a series of interesting photos from the Soviet Space program (as well as some other topics). Most notably they have a page devoted to Soviet Moon Images which features the Luna-3 images (the first images made of the dark side of the moon), through to Luna 24 in 1976 (the last spacecraft to land on the moon).
Mental Landscape also has pages devoted to the Soviet Exploration of Venus and Nikola Tesla.
Don Mitchell is the creator of Mental Landscape, and for the curious he maintains a blog here.
