Total posts from Topography 146 Search Mysteries of Compton Crater The oblique view of part of the north-central floor of Compton crater (center lat 55.9°, center lon 104.1°) shows floor fractures, the north slopes of its central peaks (center right), thousands of impact craters (some less than a meter wide), and dark floor material produced by ancient volcanic eruptions (top). North is to the left, east is toward the top, and the image spans 40 kilometers from top to bottom. NAC image pair M1251237173LR [NASA/GSFC/Arizona State University]. Published on 10 Apr 2019 Chladni 225 Chladni crater (center lat 3.96°N, center lon 1.11°E) is a classic bowl-shaped "simple" lunar crater located in Sinus Medii ("central bay"). The image displays the north and east parts of the 13.1-kilometer-wide crater, including part of its surrounding ejecta blanket, upraised rim, and bright, steep interior wall. The central and eastern parts of its lumpy, crater-pocked floor are visible at lower left. Image width across the bottom is nine kilometers. NAC image pair M1190702052LR [NASA/GSFC/Arizona State University]. Published on 21 Feb 2019 Lobate Scarps: The Movie Lobate scarps - like those shown here on the floor of the farside crater d'Alembert - are not large, but they tell us much about how hot the Moon was when it was born and its ongoing thermal evolution. Image width is about four kilometers.

This extreme closeup of the south side of 86-kilometer-diameter Tycho Crater shows melt flows and pools, small craters, sagging slopes that look like ripples, boulders, and, at the top, part of the crater rim. North is at the top. Image width is about 10 kilometers [NASA/GSFC/Arizona State University]. Published on 08 Oct 2018 Self-Inflicted Secondaries? This portion of an impact melt flow at Aristarchus Crater, centered at 24.6°N, 321.1°E, includes modified small craters and overlapping melt flows. What do the shapes of craters on impact melt and the statistics derived through careful analysis of crater density tell us about the crater formation process and timing of subsequent events? Image is 1.38 km (0.86 mi) wide. Image NAC M181411224R [NASA/GSFC/Arizona State University]. Published on 29 Jun 2018 Towering Peak The summit of the unnamed peak in the foreground (50.2° S, 236.6° E) has an elevation of 6710 meters, about 7000 meters of relief relative to the low point at the bottom of the image. The two peaks on the horizon, 200 kilometers in the distance, have summit elevations of 4320 meters and 4680 meters, respectively and both rise more than 6000 meters above their surroundings.

Published on 15 Jun 2018 Curiously Fast Degradation of Small Lunar Craters Taurus-Littrow valley, geologic exploration target for Apollo 17 and the Lunar Reconnaissance Orbiter Camera study team led by Dr. Prasun Mahanti. 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 NAC Anaglyph: Humboldt Crater Floor A floor fracture and central peak structure on the floor of Humboldt Crater (207 km diameter) that formed directly after impact. Intrusive volcanic activity likely caused the floor of the crater to lift up and then fracture [NASA/GSFC/Arizona State University]. Published on 06 Apr 2018 On the Rim! Spectacular oblique view of the rim of Shackleton crater (21 km diameter, 89.66°S, 129.20°E). While no location on the Moon stays continuously illuminated, three points on the rim remain collectively sunlit for more than 90% of the year. These points are surrounded by topographic depressions that never receive sunlight, creating cold traps that can capture ices, NAC M1224655261LR [NASA/GSFC/Arizona State University].
