Friday, November 20. 2009Central Peak of Rutherfurd LROC NAC view of boulders, on the floor of Rutherfurd crater, about to disappear into the shadows of dusk. Image width is 510 meters [NASA/GSFC/Arizona State University]. Continue reading "Central Peak of Rutherfurd" Tuesday, November 17. 2009Mountains of the Moon Most mountains on the Earth are formed as plates collide and the crust buckles. Not so for the Moon, where mountains are formed as a result of impacts. Images taken looking across the landscape rather than straight down really bring out topography and help us visualize the lunar landscape. However such images can only be taken as the spacecraft rolls to the side, in this case about 70°, so the opportunities are limited. Foreground is about 15 km wide, view is northeast across the north rim of Cabeus crater [NASA/GSFC/Arizona State University].

He had to change the flight plan and fly the LM westward to find a safe landing spot. Image 742 meters wide, north is up [NASA/GSFC/Arizona State University]. Continue reading "High Noon at Tranquility Base" Friday, November 6. 2009Ejecta Blanket Features Interactions between the mobilized material excavated during impact and the pre-existing surface formed dune-like and trough-like features in the ejecta blanket of Galvani B, a 15-km diameter crater. North is up, image resolution is 0.58 m/pixel [NASA/GSFC/Arizona State University].

Image width is 1.08 km [NASA/GSFC/Arizona State University]. Continue reading "The Floor of Saha E" Friday, October 23. 2009Epigenes A A plethora of boulders surrounds braided flows of impact melt along the inside wall of crater Epigenes A. As the melt moves toward the crater floor (direction indicated by white arrow), the flow buries and moves boulders. Epigenes A is a 18 km diameter crater located at 66.9°N and 0.3°W on the rim of crater W. Bond. The NAC image is 540 meters wide [NASA/GSFC/Arizona State University].
