Science Derived Due to the tilt of the Moon's spin axis (1.54 degrees), some regions near the poles are in permanent shadow while other nearby regions remain illuminated for the majority of the year. This subtle tilt causes lighting changes from lunation to lunation. The poles are most illuminated at their respective summer solstice. Thus images for the NAC north pole mosaic were acquired during the northern solstice (2010-01-18 through 2010-06-07), and layered in order of the greatest incidence angle and sub-solar latitude closest to the pole. The mosaic has a latitude range of 85.5 to 90 degrees and is stored as 40 polar stereographic map tiles. The tiles are in latitudinal bands of 1.5, 1, 1, and 1 degrees radiating from the pole. There are four tiles in the first band (88.5 to 90 degrees latitude), eight in the second (87.5 to 88.5 degrees latitude), twelve in the third (86.5 to 87.5 degrees latitude), and sixteen in the fourth (85.5 to 86.5 degrees latitude). NAC images were map projected onto the GLD100 DEM using the LOLA crossover corrected ephemeris. The images were not registered to one another. Stereographic projection at 1 meter/px centered at 90N, 0E with a radius of 1737400 m. The center of this tile is at 89.2N, 135.0E. For more information see [WAGNERETAL2015].
