034-The Moon from Clem-PolarAreas.jpg110 - Polar Areas: the Peaks of Eternal Light54 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.

035-The Moon from Clem-PolarAreas.jpg111 - Polar Areas: Views of the South Pole55 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.

081-The Moon from Clem-SouthPole.jpg112 - Polar Areas: View of the South Pole54 visiteMosaic of about 650 Clementine images of the South Pole of the Moon, from 80° South Lat. to the Pole (center). The Near-Side of the Moon is the top half of the image; the bottom half is the Far-Side. The dark region near the Pole indicates an old depression, inside the rim crest of the South Pole-Aitken Basin. Large parts of this area (about 15.000 Km2) are permanently shadowed and bistatic radar results from Clementine indicate that they could contain deposits of water ice.

082-The Moon from Clem-NorthPole.jpg113 - Polar Areas: Views of the North Pole54 visiteMosaic of about 750 Clementine images of the North Pole of the Moon, from 80° North Lat. to the Pole (center). The Near-Side of the Moon is the bottom half of this mosaic and the top half is on the Far-Side. In contrast to the South Pole (slide #111), the North Pole shows very little area in permanent shadow (only about 500 square-Km). This suggests that any "cold traps" in this Region of the Moon are very restricted and little ice could be stable in this part of the Moon.

71-moon_northpole 1.jpgThe Lunar North Pole (1)60 visiteUna bellissima coppia di immagini ad Alta Risoluzione dell'area Nord Polare della Luna, alla ricerca - ancora una volta - dei "Picchi della Luce Eterna" (anche se poi, come già avemmo occasione di dire in passato) si dovrebbe trattare non di picchi (nel senso di porzioni superiori di montagne appuntite), bensì di altopiani.
Comunque sia, queste Regioni della "Luce Eterna" esistono, sappiamo dove sono e, forse, costituiranno davvero un punto di partenza verso la costituzione di un avamposto Lunare permanente.
Staremo a vedere...

72-moon_northpole 2.jpgThe Lunar North Pole (2)73 visiteCaption ESA originale:"(...) This picture is valuable as it shows illumination conditions at the Region. It is important to understand global illumination conditions to help in planning the location of future landing sites and, later, possible bases on the Moon".
