New impact crater on the Moon! Since this crater is not visible in images from the Apollo 15 mission, it formed sometime in the last 38 years. The new crater is only ~10 meters (30 feet) across, but its bright ejecta extends much farther, making it stand out from all the nearby craters. LROC NAC image M108971316L; view is 400 m across [NASA/GSFC/Arizona State University]. Published on 27 Jul 2010 Alphonsus crater mantled floor fracture LROC NAC closeup of a fracture in the floor of Alphonsus crater. Dark pyroclastic materials are intermixed with lighter rocks and boulders from the fracture walls and all appear to have moved in streamers toward the fracture floor at upper right. A NASA Constellation site is centered just to the southeast of this view. Image width is 538 m, NAC image M111606491L [NASA/GSFC/Arizona State University]. Published on 02 Apr 2010 Surveyor 5: A hole-in-one Surveyor 5 sitting in a 10 meter diameter crater, LROC NAC image M106726943LE, width ~960 meters [NASA/GSFC/Arizona State University]. Published on 21 Mar 2010 Crisium's Constellation Region of Interest Boulders on a wrinkle ridge in Mare Crisium may help us understand the geology of this Constellation region of interest. The scene is 460 meters across; image number M119469420LE [NASA/GSFC/Arizona State University]. Published on 11 Mar 2010 Out of the Shadows: Impact Melt Flow at Byrgius A Crater Spectacularly preserved viscous flow on the NE rim of Byrgius A (19 km diameter) crater. This flow has a form similar to lava flows on the Earth - however it formed as a result of an asteroid or comet slamming into the Moon at hyper-velocity (>16 km/second). So much energy was released in the impact that solid rock was melted and thrown out of the crater where it flowed down the crater flanks (M102573276L, image width 810 m) [NASA/GSFC/Arizona State University]. Published on 02 Feb 2010 Cluster of farside secondary craters Cluster of secondary craters help geologists determine the relative ages of features, even when they are separated by great distances. Image width is 630 meters [NASA/GSFC/Arizona State University]. Published on 23 Nov 2009 Mountains 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]. Published on 17 Nov 2009 Apollo 14 S-IVB Impact Crater Crater (center of image) formed by impact of the Apollo 14 Saturn IVB booster. The booster was intentionally impacted into the lunar surface on February 4, 1971 to serve as an energy source to probe the interior structure of the Moon using seismometers placed on the surface by Apollo astronauts [NASA/GSFC/Arizona State University].
