LROC NAC oblique of Montes Recti (right), a range of highlands massifs about 80 km across from west-to-east (west is at the top in this view) near the northern rim of Mare Imbrium. A wrinkle ridge deforms the mare basalts surrounding the range and forks into two segments near where it intersects the massifs. Image M1274273192LR, centered at 48.3° N, 340.3° E. Published on 28 Sep 2022 The Ins and Outs of Secondary Craters Secondary craters and v-shaped ejecta. The largest crater at center is about 90 meters in diameter.

Published on 05 May 2022 From the Moon to Jupiter, with Love Jupiter seen from the Moon, as imaged by the Lunar Reconnaissance Orbiter Camera on 20 August 2021. Two of Jupiter's moons, Io and Europa, can just barely be seen here to the right of Jupiter (keep reading for a labeled version). Scene has been enlarged by a factor of four; Image M1384139607L [NASA/GSFC/Arizona State University]. Published on 14 Sep 2021 Plumbing the Depths by Scaling the Heights The central mountainous peaks of Maunder crater are thought to be made of rock that was melted by the impact event that resulted in the Orientale basin. This impact melt rock deposit was then lifted up from below the surface during the Maunder impact event. Material that was melted by the younger Maunder impact event ponded and solidified at the base of this mountain (bottom of the scene). Scene is 2.75 km across and centered at 14.62° S, 266.21° E; NAC image M1200748730LE [NASA/GSFC/Arizona State University]. Published on 19 Feb 2020 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 Searching for Ice at the Moon's Poles Flank, rim and shadowed interior of Sylvester N crater (20 km diameter, 82.41°N, 291.32°E). Left stretch shows off details of illuminated ground while right stretch brings out details of permanently shadowed interior, which is illuminated with light that bounced off the far crater wall. NAC M1119450011LR, image width 5712 meters [NASA/GSFC/Arizona State University]. Published on 19 Dec 2017 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 The History of Volcanism in the Moon's Largest Basin A view of the Moon's largest impact feature, the South Pole–Aitken basin, so named because it stretches between Aitken crater and the south pole. The orthographic projection here centered on the basin (53°S, 191°E) highlights how much of the lunar farside was affected by this ancient impact event. A new study investigates the duration of volcanism within the basin [NASA/GSFC/Arizona State University]. Published on 02 Nov 2017 Investigating Newly Discovered Lobate Scarps Joy scarp (25.28°N, 6.84°E) extends from the lower left to upper right across this scene, and is found northeast of Joy crater (not seen) in a hummocky terrain between Mare Imbrium and Mare Serenitatis. Ejecta from the fresh, 300-m diameter impact crater at center-left covers portions of the lobate scarp. The direction of sunlight is from the east (right), image M177589050LR. [NASA/GSFC/Arizona State University] Published on 05 Oct 2017 Mons Hansteen: A Window into Lunar Magmatic Processes Oblique view of Mons Hansteen, located near the southern margin of Oceanus Procellarum at 12.3° S, 309.8° E. This enigmatic landform is thought to be a volcanic complex and one of only a handful of known sites on the Moon composed of silica-rich rocks.
