Total posts from Copernican Crater 92 Search Ejecta from Copernicus One of the geologic features that makes Copernicus crater special is its extensive, high-reflectance ejecta rays that extend across nearby mare and superpose (overlap) ejecta from other craters - Copernican ejecta extends more than 500 km from the impact site! In this high-Sun image, albedo differences are enhanced and the arrows indicate several "fingers" of ejecta and the direction of ejecta emplacement (away from Copernicus, which is to the southwest). LROC NAC image M127050121L, image width is 470 m [NASA/GSFC/Arizona State University]. Published on 30 Sep 2010 Copernicus Crater and The Lunar Timescale LROC NAC view of the southern rim of Copernicus crater. Downslope direction is to the upper left and the fragmented material demarcates the rough edge of the crater rim. The surface texture is still sharp and crisp indicating a relatively young age - note the boulder tracks! LROC NAC image M129418341L, image width is 470 m [NASA/GSFC/Arizona State University]. Published on 28 Sep 2010 Necho's Terraces Closeup view of the spectacular western terrace of Necho crater. NAC image M134388215R; scene width is 660 m [NASA/GSFC/Arizona State University]. Published on 31 Aug 2010 Forked Impact Melt Flows at Farside Crater Impact melt flow split into two distinct segments. The source crater is 2.5 km to the south in a region of the farside highlands ENE of Mare Moscoviense. Image width is 1.3 km, and the pixel width is 1.25 m, NAC Image M112902715L, illumination is from the right [NASA/GSFC/Arizona State University]. Published on 22 Jun 2010 Exposed Fractured Bedrock in the Central Peak of the Anaxagoras Crater NAC image of the Anaxagoras crater floor, including a portion of the crater's anorthositic central uplift. The boulders perched on ridges are eroding out of densely fractured bedrock. Image number M122273232R [NASA/GSFC/Arizona State University]. Published on 14 Apr 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 King Crater's Unusual Melt Pond A Constellation Program Region of Interest near the northeast edge of the unusually large melt pond adjacent to the lunar far side crater King. The boundary between the dark, coherent impact melt rock at the lower left of the image and the bright, pulverized ejecta blanket to the upper right is clearly visible in the floor of a smaller crater that formed at the boundary between these two units. Image width is 1.3 km, pixel width is 1.29 m. Subset of NAC frame M106088433R [NASA/GSFC/Arizona State University]. Published on 26 Jan 2010 Fresh Copernican Crater Subset of NAC Image M112162602L showing landslides (bottom) covering impact melt on the floor (top) of a fresh Copernican-age crater at the edge of Oceanus Procellarum and west of Balboa crater. Image width is 550 m [NASA/GSFC/Arizona State University]. Published on 21 Dec 2009 Impact Melt Flows on Giordano Bruno Frozen impact melt flows on the ejecta blanket of the young impact crater Giordano Bruno (22 km diameter). The image is about 600 m across and the flows are about 50-100 m wide (NASA/GSFC/Arizona State University). Published on 15 Dec 2009 Milichius A The inner rim of Milichius A crater in Mare Insularum. Image width is approximately 6 km wide [NASA/GSFC/Arizona State University]. Published on 18 Sep 2009 Prev 1 … 6 7 8 9 10 Next ← Previous Next → Displaying Post 81 - 90 of 92 in total
