NASA releases a giant interactive mosaic image of the lunar north pole. It took four years to create and covers an area equivalent to a quarter of the US.
A complete printout of the images collected, would require a square sheet of paper wider than a football field.
Web viewers can zoom in and out, and pan around an area. Constructed from 10,581 pictures, the mosaic provides enough detail to see textures and subtle shading of the lunar terrain. Consistent lighting throughout the images makes it easy to compare different regions.
