The_Moon-Aristarchus_Plateau.jpgAristarchus Plateau: the cradle of TLP's78 visiteCaption NASA:"Anchored in the vast lava flows of the Moon's Oceanus Procellarum lies the Aristarchus Plateau. The bright impact crater at the corner of the plateau is Aristarchus, a young crater 42 Km wide and 3 Km deep. Only slightly smaller, lava flooded Herodotus crater is above and to the left.
A valley (or rille) feature likely carved by rapidly flowing lava or a collapsed lava tunnel, Vallis Schroteri begins just to the right of Herodotus and winds across the plateau for about 160 Km, eventually turning toward the top of the picture.
Aristarchus Plateau itself is like a rectangular island about 200 km across, raised up to 2 kilometers or so above the smooth surface of the lunar Ocean of Storms.
Recorded from a backyard observatory in Buffalo, New York, the contrast of light-colored ejecta around Aristarchus with surrounding dark, smooth, lava flooded surfaces suggests more familiar snowy scenes of planet Earth".MareKromium

ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-The Moon.jpgMare Imbrium, from Galileo77 visiteCaption NASA originale:"Checking out the Galileo spacecraft's cameras during its December 1992 fly-by of Earth's Moon, controllers took this dramatically illuminated picture through a violet filter. The view looks down on the Moon's North Polar Region with the Sun shining from the left at a low angle and the direction toward the Moon's North Pole toward the lower right.
Across the image upper left stretches the smooth volcanic plain of the Mare Imbrium. Pythagoras crater, 65 miles wide, is near the center of the image -- mostly in shadow, its central peak just catches the sunlight (...)".

ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-The Moon-1.jpgThe Moon from Galileo75 visiteCaption NASA originale:"The Moon's surface is covered with craters, scars of frequent impacts during the early history of the Solar System. Now, recent results from the Lunar Prospector spacecraft support the idea that the Moon itself formed from the debris of a giant impact of a Mars-sized planetary body with the Earth nearly 4,5 BY ago. The impact theory of lunar origin can explain why Moon rocks returned by the Apollo missions have the same isotopic ratios as Earth rocks while the Moon seems deficient in heavy elements like iron. It can also explain a critical finding of the Lunar Prospector experiments - that the Moon's core is proportionally very small. If the Moon formed simply as a Sister World, its origin paralleling Earth's formation from the primordial Solar Nebula, it should have similar iron content and relative core size. But material blasted from the surface of Earth by an impacting body would lack the iron and heavy elements which had settled to the Earth's core yet retain similar ratios of chemical isotopes. A fraction of this debris cloud would remain in Earth orbit ultimately forming the Moon".
