Over the Pole

image from Stardust spacecraft, processed by Ted Stryk

Ted has rescued images. Ted corrected for the fogging by looking at how far it extended beyond the limb and used an estimate of the brightness of the limb area to compare to the brightness of the fog. It took literally a few months of trial and error before it worked. He then stacked a number of the images and used standard image enhancement techniques to produce this cleaned up view with an unfamiliar perspective. The bright Copernicus-like crater near the mid-point of the image is Pythagoras and the north pole is near the top of the image at the terminator. The 90°W limb (as seen from Earth) would be a slanted line that skirts the left side of Oceanus Procellarum. The large crater near the top is the farside basin Birkhoff (148°W, 59°N) with an arc of its inner ring clearly visible. The rest of the farside visible with this view and resolution is rather boring. We are lucky to have the interesting side of the Moon facing Earth!
