The Project Gemini Online Digital Archive was released recently by NASA, in conjunction with Arizona State University's School of Earth and Space Exploration.
What we have is a collection of high-resolution photos, which have been scanned from the original mission flight films, spanning ten missions between 1965 and '66. The one thing you can probably take note of while flicking through the photos is the beauty of it all. The photos provide an amazing insight into the history of American space exploration, you can't help but relive the fascination about the great beyond when you see the pictures. That sense of wonderment that seems to have been lost in the face of reduced government funding, the questions you always asked about what exists beyond the unknown.
