033-The Moon from Clem-Aristarchus-3.jpg041 - Aristarchus and Vallis Schroteri56 visiteThe plateau of the Aristarchus Crater has experienced intense volcanic activity, both effusive and explosive.
It includes the densest concentration of Lunar "sinuous rilles" ("snake-like" valleys) including the largest known, Vallis Schroteri, which is about 160 km long, up to 11 km wide and 1 km deep.
The rilles in this area begin at cobra-head craters, which are the apparent vents for a dark mantling deposit covering the plateau and nearby areas to the North and East.

018-The Moon from Clem-WestLimb-PIA00305.jpg004 - The western limb of the Moon: Mare Orientale and Oceanus Procellarum55 visiteThe so-called Mare Orientale (ringed feature just below image center) is just visible from Earth on the extreme western edge of the Near-Side of the Moon.
Oceanus Procellarum (large dark albedo area in upper right of image) is a familiar Near-Side feature as seen from Earth.

019-The Moon from Clem-EastLimb-PIA00303.jpg005 - The eastern limb of the Moon: Mare Smythii, Mare Marginis, Mare Crisium and Mare Fecunditatis55 visiteThe dark albedo features Mare Smythii (image center) and Mare Marginis (above Smythii) are just visible from Earth on the extreme eastern edge of the Lunar Near-Side. Mare Crisium (West of Marginis) and Mare Fecunditatis (SouthWest of Crisium) are familiar Near-Side features as seen from Earth.
Maria Regions are believed to be large basins formed by impacts from cosmic projectiles later filled by basaltic lava flows from volcanic eruptions. Basaltic lava flows on the basin floors give maria their dark albedo appearance.

030-The Moon from Clem-Copernicus.jpg054 - Copernicus55 visiteCopernicus is a rayed crater, 97 Km in diameter, that formed about 800 MY ago. In this image of the Crater Copernicus, color differences are shown for the eastern half of the crater.
A false-color mosaic is created by making ratio images and assigning each to one of the 3 primary colors: the red channel is controlled by the 750/415-nnmts ratio; the green channel is controlled by the 750/950-nnmts ratio and the blue channel is controlled by the 415/750-nnmts ratio.

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.

082-The Moon from Clem-NorthPole.jpg113 - Polar Areas: Views of the North Pole55 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.

NearsideAlbedo.JPG007 - Nearside Albedo55 visiteGlobal map of the albedo from the 750-nanometer filter of the Clementine UV-VIS camera. This is the NearSide of the Moon, shown in Lambert equal-area projection.
Note the familiar appearance of the maria; the fresh, rayed crater near bottom center is Tycho.
This view has been subsampled to a resolution of about 1 Km per pixel, about 5 times lower than the full-resolution data.

MoonEclypse.JPG025 - Sun-Eclypse from Clementine55 visiteThis Startracker image shows the Moon eclipsing the Sun; the bright crescent Earth is partially visible at left, saturating the sensor.
The image was captured during orbit 164, on March 26, 1994, halfway through Moon mapping at a distance of about 3500 km.
