035-The Moon from Clem-PolarAreas.jpg111 - Polar Areas: Views of the South Pole58 visiteThe spin axis of the Moon is nearly vertical (inclined 1,6°) to the ecliptic plane (the plane of its orbit around the Sun), in marked contrast to the Earth (axis inclination 23,5°). However, even this small inclination means that the hemispheres of the Moon experience seasons as the Pole tracks toward and away from the Sun. Clementine started its lunar mapping in the dead of Southern Winter (axis away from the Sun), but by the 2nd month of mapping, the axis had begun to point closer in that direction. These two mosaics show the difference in lighting conditions between the first month of mapping (left, maximum winter) and the second month's coverage (right, toward the solstice).
Careful examination of the two mosaics reveals some slight shadow changes; note in particular the shadows that cover the floors of the craters Amundsen and Scott (large central peak crater at about 3 o'clock and the crater just above it). However, the large region of permanent shadow near the center of the mosaics discovered by Clementine remains virtually unchanged in the two mosaics.

034-The Moon from Clem-PolarAreas.jpg110 - Polar Areas: the Peaks of Eternal Light56 visiteAs Clementine flew over the Pole - every 5 hours - it began its photographic mapping pass by imaging the Pole. These images are composites, showing the addition of alternate orbit polar images over the course of 1 Lunar Day (such as 1 Earth month). In these composite maps, areas in permanent darkness are black, while areas of permanent illumination are white; areas of mixed lighting condition are represented in various shades of gray. Note that the South Polar Area has the largest area of permanent darkness, measuring more than 15,000 square kilometers. The north pole shows only about 500 square kilometers of darkness. Several areas are evident that have near-constant Sun illumination. Such zones would have great value as sites for a permanent lunar outpost.

FarSideAlbedo.jpg006 - Farside Albedo61 visiteGlobal map of the albedo from the 750-nanometer filter of the Clementine UV-VIS camera and this is the FarSide of the Moon, shown in Lambert equal-area projection.
Note the lack of maria on the FarSide, as compared to the NearSide.
The relatively dark area at center-bottom outlines the extent of the South Pole-Aitken Basin. This view has been subsampled to a resolution of about 1 Km per pixel, about 5 times lower than the full-resolution data.

040-The Moon from Clem-Apollo 16 LandingSite.jpg216-0 - The Apollo 16 "Landing Site" (in natural colors)62 visiteThis is the Apollo 16 Landing Site as seen from Clementine. This is a natural color rendition of the site. Clementine images were deliberately taken at very low phase angles (which means high Sun angles) to emphasize color differences, so surface textures are much less apparent here than in the orbital Apollo view.
Note the very bright appearance of South Ray and North Ray Craters (center right).
Promemoria: l'angolo "di fase" è l'angolo formato da Sole, corpo/rilievo ripreso e Sonda.
