Total posts from Ejecta 102 Search South Massif Landslide By lunar standards South Massif is a relatively modest mountain, but with a rich history (geologic and exploration). The massif is about 7000 meters across at the base and 2300 meters tall; M1266925685LR, incidence angle 33°, slew angle 65°, phase angle 104° [NASA/GSFC/Arizona State University]. Published on 08 Jun 2018 Hell Q Crater Recent impact craters are some of the most spectacular landforms on the Moon! For example, Hell Q (3.4 kilometers in diameter, 33.0° S, 355.5° E) shows off pristine impact melt that lined the crater walls and pooled in the bottom, now solidified into rock.Ejecta was thrown out several crater radii, and dark impact-melt streamers that formed late in the impact process crossed over the early emplaced ejecta; NAC M1221369684LR [NASA/GSFC/Arizona State University]. Published on 27 May 2018 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.

Center latitude 20.15°N, center longitude 30.98°E, image 18 km wide, image M1182232465LR [NASA/GSFC/Arizona State University]. Published on 24 Apr 2018 Lunar Light Plains: The Movie The Orientale Basin, about 950 kilometers wide, is the striking multi-ringed impact feature at lower right. New research suggests that the impact event that formed Orientale may have emplaced light plains deposits - visible here in green - over a large portion of the lunar surface. Image width: 3475 kilometers (the width of the Moon) [NASA/GSFC/Arizona State University] Published on 19 Apr 2018 Luminous Pierazzo Crater The Moon continues to surprise us with its beauty! When did this magnificent crater form? From its pristine state it looks as if it could have formed yesterday, however erosion proceeds slowly on the Moon. NAC M1265532953LR, scene is ~11 km wide [NASA/GSFC/Arizona State University.] Published on 13 Feb 2018 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 Tycho Limb Shot! Magnificent oblique view of the eastern side of Tycho's central peak acquired when the Sun was relatively high above the horizon. From the viewpoint of LROC the Sun was behind and a bit to the north, so shadows are mostly hidden, thus subtle changes in surface brightness dominate the scene. Image width ~8 km, north is to the right, M1167178525LR [NASA/GSFC/Arizona State University]. Published on 27 Apr 2017 NAC Anaglyph: Buffon Flow Front This lobate flow, found to the south of Buffon crater, likely formed as fluidized basin ejecta moved across the surface [NASA/GSFC/Arizona State University]. Published on 06 Jan 2017 Mapping Tycho Crater A new geomorphological map of the interior of Tycho crater, produced using LROC NAC and SELENE Terrain Camera images.
