Project Gemini archives the history of space exploration in photos
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.
