NASA's Uncensored Moon Images!



Here are the uncensored Moon Images taken by the Lunar Orbiter!
According to Arizona State University, the Lunar Orbiter images were all digitally scanned at 400 dpi at the Lunar and Planetary Institute in Houston. Whole images were too large to be scanned at once and were broken up into four sections.

From the data and resources about each lunar orbiter image found in Anderson and Miller (1971), they obtained information about the side length, altitude and emission angle of the images they scanned. To calculate the resolution of each image they followed several steps. They first calculated the resolution of images with an emission angle of less than 10° by dividing the side length of each image by the number of pixels, and then calculated the distance to the surface by dividing the altitude by the cosine of the emission angle. The resolution of low-emission angle images was plotted against their distance to the surface. From this was obtained the best-fit equation:
Corrected Resolution = -0.0023272 + 0.014376 * Distance to Surface
and applied it to the remaining images to get the corrected resolution.
