LROC NAC M1107532088RE, image width is ~1000 m [NASA/GSFC/Arizona State University]. Published on 20 Dec 2012 Terraced Craters in Aitken Crater Small crater within Aitken crater. It has a terraced and hummocky floor, with boulders strewn about, and no bright rays. NAC image M145855135RE, image width is 700 m [NASA/GSFC/Arizona State University]. Published on 25 Jan 2011 Probing the Lunar Surface Using Small Impact Craters A fresh impact crater with finely detailed ejecta patterns. How has this crater changed since it was formed? Can the shape of this crater tell us anything about the surface in which it formed? The crater cavity (centered at 20.870°S, 350.299°E) is roughly 185 m in diameter, LROC NAC M183588912R [NASA/GSFC/Arizona State University]. Published on 20 Oct 2017 Dark landslide near van Gent crater A landslide within a small crater near van Gent crater. The crater rim is in the top right while the crater floor is in the bottom left. The landslide has exposed many boulder within the crater wall. LROC NAC M156550640RE, image width is 600 m [NASA/GSFC/Arizona State University]. Published on 18 May 2011 Aitken Crater Constellation Program Region of Interest A lobate scarp in the mare basalts of Aitken crater on the lunar farside (arrows). Aitken crater is one of the fifty regions of interest in NASA’s Constellation Program. The smooth mare basalts that flooded the floor of Aitken crater are relatively few on the lunar farside. Mare basalts often have wrinkle ridges and lobate scarps, tectonic landforms that express contraction of the volcanic flows. Future astronauts who might visit Aitken crater will explore this landform in search of clues to how this and other lobate scarps form. Image width is 4.5 km, NAC frame M103374879RE [NASA/GSFC/Arizona State University]. Published on 12 Jan 2010 New Impact Crater on the Moon! 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 Every Crater on the Moon (Larger than 5 km) New work from the LROC team resulted in a map of all detectable craters on the Moon between 5 and 20 km in diameter (red circles). When combined with an existing map of craters larger than 20 km in diameter, the differences in the density of craters of different diameters in different areas provides information about the geologic history of that surface [NASA/GSFC/Arizona State University]. Published on 13 Nov 2017 Two-toned Impact Crater in Balmer Basin: A Reflection of the Target? Materials excavated during formation of this ~450 m diameter impact crater have an unusual two-toned character, likely a reflection of heterogeneity in the target materials. This crater occurs in Balmer Basin, an area thought to harbor a type of 'cryptomare' - an old volcanic surface covered by later light-toned impact deposits. The dark materials may be basaltic rock excavated from deeper parts of the crater. The crater is located at 18.341°S latitude and 69.950°E longitude. The scene is 540 m across, a subset of NAC M111138159LE [NASA/GSFC/Arizona State University]. Published on 26 Mar 2010 Not your average complex crater The small, irregular terraces on the walls of Bürg Crater and the debris piles and outcropping wall material, with strong variations in reflectance, only hint at the geologic diversity of this complex crater. Bürg's crater rim is on the upper left, with downslope direction toward the lower right. Illumination is from the right, image width is 870 m, LROC NAC M116139887R [NASA/GSFC/Arizona State University]. Published on 28 Jul 2010 Hawke Crater Hawke crater, 13.2 km wide, is noticeably tilted because the impactor - an asteroid or a comet - that excavated it struck the sloping inner wall of Grotrian crater. Visible are light-colored rays that attest to the crater's youth, as well as subtle signs of darker impact melt. Image width is about 20 km, -66.61 lat, 128.65 lon. Image number M1258054744.
