Published on 19 Dec 2016 NAC Anaglyph: Orientale Rille A sinuous rille in the Orientale basin exhibits fresh exposures where landslides have occurred along steep portions of the walls [NASA/GSFC/Arizona State University]. Published on 18 Nov 2016 Color of the Lassell Massif A shock of color on the Moon! The Lassell Massif (a so-called "red spot") in Mare Nubium appears orange in the center of this WAC color composite image. The image was derived by assigning red to 689 nm, green to 415 nm, and blue to 321 nm images. The image was enlarged by a factor of two for viewing here (the original data was sampled to 400 m per pixel); north is up. Image is 190 km across. [NASA/GSFC/Arizona State University]. Published on 12 Sep 2016 What's Next for LRO? LRO and LROC will continue to explore the Moon during the mission's third extended mission to understand fundamental processes that shape our Solar System. Published on 22 Aug 2016 Age of the Compton-Belkovich Volcanic Complex A small portion of the Compton-Belkovich Volcanic Complex (61.20°; N, 100.27°; E) as you would see it from the window of your personal lunar module flying at an altitude of 52 km above the surface, looking to the west-southwest. The upper two thirds of the scene shows the volcanic complex, whereas the lower third of the image is outside of the complex. The terrain outside of the complex exhibits a greater abundance of impact craters than inside the complex. Image M174549036LR [NASA/GSFC/Arizona State University]. Published on 29 Jun 2016 Dome in Mare Vaporum NAC anaglyph of a prominent volcanic dome in Mare Vaporum [NASA/GSFC/Arizona State University]. Published on 20 Nov 2015 NAC Anaglyph: Aristarchus Rille Vallis Schroeteri, a large lunar rille, winds its way across the Aristarchus Plateau. At this location, Vallis Schroeteri is nearly 4.5 km across! Note the smaller, more sinuous rille nested within the larger rille [NASA/GSFC/Arizona State University]. Published on 13 Nov 2015 Exploring the Lunar Subsurface What a great place to explore! Two collapsed segments of a lava tube run from the southwest to the northeast. These collapsed segments may provide access to the subsurface, which has never been directly sampled. The average width of the collapsed segments is ~650 meters. The lava tube is ~50 meters deep in this LROC NAC mosaic (M1165080128LR). Image width is approximately 7 km [NASA/GSFC/Arizona State University]. Published on 05 Nov 2014 New Evidence For Young Lunar Volcanism! One of many newly-discovered young volcanic deposits on the Moon (4.330°N, 33.750°E), this example is near the crater Maskelyne. The direction of sunlight is from the right and north is up, NAC M1123370138R [NASA/GSFC/Arizona State University]. Published on 12 Oct 2014 Tadpole and Lava Tube An irregularly shaped depression, resembling a tadpole (center left), which is part of a sinuous chain of pits. The black arrow indicates the beginning of the pit chain that trends to the southeast. This feature is about 8 km long and 600 m deep, and is located in the mare northwest of Gruithuisen crater. Color shaded-relief depicts elevation from NAC DTM PITVENT; higher elevations are red and white, lower elevations are blue and purple; north is up [NASA/GSFC/Arizona State University].
