The header for each page was produced from a thermal image of the region of Mars taken during the 2001 Mars Odyssey mission. The region pictured is approximately 20 by 40 miles. The image was flipped, duplicated twice, spliced, and then digitally altered by sampling from itself to hide the fact that the image had been tiled. The colors were obtained by splitting apart the color channels, extracting pure colors from them, then combining the pure colors with grayscale representations of the original channels in layers of varying opacity. By this method very rich colors were obtained. In short, a lot of unscientific things were done to the original image, which was made available courtesy NASA/JPL/ASU. |
