Earth.JPG300 - The Earth from Clementine60 visiteThis was imaged by the High Resolution Camera at 750 nm on 11 April 1994 during lunar orbit 242. This mosaic was put together from over 70 HR images as the Clementine spacecraft's attitude was adjusted to scan the sensor across the Earth in strips.
The image shows a 2° by 2° field of view and has a resolution of 6 Km from a distance of about 380.000 Km.
Africa and the Middle East are clearly visible on the right, with South and Central America visible on the left.
The Caribbean, Florida and the the Eastern US (mostly under cloud cover) are visible near the top of the image. North is to the upper right.

NearsideAlbedo.JPG007 - Nearside Albedo57 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.

Moon-Clem.JPG015 - The Moon (visible and near-infrared)55 visiteOne of the major scientific goals of the Clementine mission is to map the Moon in 11 different wavelengths in the visible and near-infrared parts of the spectrum. The filter colors of the Clementine cameras were carefully chosen to differentiate types of lunar surface material. In our first look at the global color, each Clementine image made by the UV/VIS camera has been reduced to its average value, producing a picture of the Moon at low resolution (about 50 kilometers per pixel). These pictures show the albedo (brightness) and color of the Moon from three aspects: the Earth-centered view (near side) with a 0 degree central longitude, and two far side views with 120 degrees East and 120 degrees West central longitudes. These images have been made by assigning colors to the relative reflectance values obtained through various filters, resulting in a map showing the compositional variation of the Moon.
Major compositional provinces in the highlands are evident. The large dark red-gray region on the far side is the South Pole-Aitken basin, an ancient impact feature that apparently contains rocks of distinct composition. A newly discovered compositional anomaly on the east limb of the Moon (pink area near center of 120 degrees East image) may be related to ancient flows of lava. The color picture shows that very high titanium lavas (deep blue and cyan colors) appear to be largely confined to the Oceanus Procellarum, Mare Imbrium, and Mare Tranquillitatis areas (near side). These views of the Moon in three colors only hint at the scientific richness contained within the Clementine global data, which will be investigated for years to come.

007-The Moon from Clem-Gagarin.JPG030 - Jules Verne Crater63 visiteThis oblique image was acquired by Clementine during orbit 255. The images used to form this color composite were taken with the UV/VIS camera at wavelengths of 415, 750, and 1000 nnmts. In the lower right are seen mare materials (flood lavas) in the floor of the impact crater Jules Verne. To the left, near the Limb of Gagarin, is another mare unit in the floor of Tsiolkovsky.

081-The Moon from Clem-SouthPole.jpg112 - Polar Areas: View of the South Pole60 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.

023-The Moon from Clem-SchroendingerBasin.jpg045 - Schroedinger Basin (detail mgnf)60 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.

029-The Moon from Clem-OrientaleBasin.jpg070 - The "Orientale" basin58 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.
