The_Earth_from_Clementine-000.jpg400 - The Earth from Clementine192 visiteView of the full Earth taken by Clementine while orbiting the Moon. This image is a mosaic of color, HR frames. Africa is clearly visible on the right and South America is visible on the left. This is a “false-color” version that makes vegetation appear red".
Image processing by United States Geological Survey (USGS), Flagstaff, Arizona
Nota: la vegetazione, in questo frame ed in accordo a quanto l'USGS stessa dice in chiare lettere, appare rossa (mentre dovrebbe essere di un bel color verde scuro) mentre le sabbie dei deserti - e questo lo diciamo noi - appaiono di color arancio-giallo (e dovrebbero vedersi esattamente come si vedono).
Curiosa questa "alterazione cromatica selettiva" in virtù della quale alcuni colori cambiano radicalmente mentre altri restano quello che sono.
Pensate adesso alle fotografie amatoriali di Marte ottenute da Terra ed a quelle "professionali&scientifiche" ottenute dall'HST e dalle Sonde che girano attorno al Pianeta Rosso. Colta la provocazione?!? Fateci sapere...Nov 01, 2005

043-The Moon from Clem-North Pole-2.jpg035 - Plaskett Crater (natural colors)56 visitePlaskett Crater ID:
Location: 82° North Lat. and 174° East Long.;
Dimension: about 110 Km in diameter
Interesting Features: the huge "central peak"

081-The Moon from Clem-SouthPole.jpg112 - Polar Areas: View of the South Pole57 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.Ott 29, 2005

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. Ott 29, 2005

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. Ott 29, 2005

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.Ott 29, 2005

040-The Moon from Clem-Apollo 16 LandingSite.jpg216-0 - The Apollo 16 "Landing Site" (in natural colors)59 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.Ott 29, 2005

023-The Moon from Clem-SchroendingerBasin.jpg045 - Schroedinger Basin (detail mgnf)57 visiteDetail from the UV-VIS Clementine Camera of the floor of the basin Schrodinger, showing the coverage (inset strip) of the HR camera for comparison. The Dark Halo Crater (center at 76° South Lat. and 139° East Long.; 5 Km across) is a volcanic vent that erupted ash during the period of mare volcanism on the Moon, more than 3,5 BY ago.Ott 29, 2005

020-The Moon from Clem-Solar Corona.jpg023 - Solar Corona57 visiteImage of the Moon taken by the Star Tracker camera onboard Clementine. The bright glow over the horizon is the Solar Corona (outer atmosphere) showing from behind the Moon. Craters at left are illuminated by Earthshine, the light reflected off the Earth and onto the Moon. The dark part of the Moon is on the Lunar Far-Side. Do not equate "Dark-Side" with "Far-Side": the Far-Side experiences the same day-night cycle (28 days) as the Near-Side.
It just happens to be night on the Far-Side in this image.Ott 28, 2005

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.Ott 28, 2005

029-The Moon from Clem-OrientaleBasin.jpg070 - The "Orientale" basin56 visiteMosaic of more than 2000 Clementine (750-nanometers) images, showing the Orientale Basin of the Moon at full resolution of about 250 mt per pixel. The Orientale Basin is about 930 Km in diameter and is only partly filled by dark, mare lava.
The relative paucity of mare basalt fill, coupled with the young age and topographic freshness of the basin, makes this feature the archetypal lunar multiring basin.Ott 28, 2005
