Schrödinger (crater)
Schrödinger is a large lunar impact crater of the form traditionally called a walled plain and is named after Erwin Schrödinger. It is located near the south lunar pole on the far side of the Moon, and can only be viewed from orbit. The smaller crater Ganswindt is attached to the southwestern rim of Schrödinger, and intrudes slightly into the inner wall. Adjacent to the south is the crater Nefed'ev. Farther to the southwest is the crater Amundsen. Schrödinger is perhaps the moon's best example of a peak-ring basin. It possesses a wide outer rim that has been slightly rounded due to subsequent impacts. But the rim remains well-defined, and traces of terraces can be seen along the inner surface. The ejecta on the exterior forms an irregular outer rampart that extends for up to 100 kilometers. Within the interior is a second ring approximately half the diameter of the outer rim. This forms a circular range of rugged mountains that surrounds the center, with the exceptio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric polar mapping orbit. Data collected by LRO have been described as essential for planning NASA's future human and robotic missions to the Moon. Its detailed mapping program is identifying safe landing sites, locating potential resources on the Moon, characterizing the radiation environment, and demonstrating new technologies. Launched on June 18, 2009, in conjunction with the Lunar Crater Observation and Sensing Satellite (LCROSS), as the vanguard of NASA's Lunar Precursor Robotic Program, LRO was the first United States mission to the Moon in over ten years. LRO and LCROSS were launched as part of the United States's Vision for Space Exploration program. The probe has made a 3-D map of the Moon's surface at 100-meter resolution and 98.2% coverage (excluding polar areas in deep shadow), including 0.5-meter resolution images of Apollo landing sites. The first images f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rille
Rille (German for 'groove') is typically used to describe any of the long, narrow depressions in the surface of the Moon that resemble channels. The Latin term is ''rima'', plural ''rimae''. Typically, a rille can be several kilometers wide and hundreds of kilometers in length. However, the term has also been used loosely to describe similar structures on a number of planets in the Solar System, including Mars, Venus, and on a number of moons. All bear a structural resemblance to each other. Structures Three types of rille are found on the lunar surface: * Sinuous rilles meander in a curved path like a mature river, and are commonly thought to be the remains of collapsed lava tubes or extinct lava flows. They usually begin at an extinct volcano, then meander and sometimes split as they are followed across the surface. , 195 sinuous rilles have been identified on the Moon. Vallis Schröteri in Oceanus Procellarum is the largest sinuous rille, and Rima Hadley is the only one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jonathan's Space Report
''Jonathan's Space Report'' (JSR) is a newsletter about the Space Age, hosted at Jonathan's Space Page. It is written by Jonathan McDowell, a Center for Astrophysics Harvard & Smithsonian astrophysicist. It is updated as McDowell's schedule permits, but he tries to publish two issues each month. Originally the website was hosted on a Harvard University account, but was moved in late 2003 to a dedicated domain. Started in 1989, the newsletter reports on recent space launches, International Space Station activities and space craft developments. McDowell's report occasionally corrects NASA's official web sites, or provides additional data on classified launches that aren't available elsewhere. Associated projects on the JSR web site are: * A catalog of all known geosynchronous satellites and their current positions * A listing of satellite launch attempts * A cross-reference between catalog number and international designation of artificial satellites McDowell has long campaigne ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Imbrian
The Imbrian is a lunar geologic period divided into two epochs, the Early and Late. Early Imbrian In the lunar geologic timescale, the Early Imbrian epoch occurred from 3,850 million years ago to about 3,800 million years ago. It overlaps the end of the Late Heavy Bombardment of the Inner Solar System. The impact that created the huge Mare Imbrium basin occurred at the start of the epoch. The other large basins that dominate the lunar near side (such as Mare Crisium, Mare Tranquillitatis, Mare Serenitatis, and Mare Fecunditatis) were also formed in this period. These basins filled with basalt mostly during the subsequent Late Imbrian epoch. The Early Imbrian was preceded by the Nectarian. Late Imbrian In the Lunar geologic timescale, the Late Imbrian epoch occurred between 3800 million years ago to about 3200 million years ago. It was the epoch during which the mantle below the lunar basins partially melted and filled them with basalt. The melting is thought to have occurred ...

Fechner (crater)
Fechner is a lunar impact crater that lies on the far side of the Moon's southern hemisphere, attached to the western rim of the large walled plain Planck. The eastern rim of Fechner intersects the Vallis Planck, a long, wide cleft in the surface that follows a course to the north-northwest. This valley intrudes into the southeastern rim of the crater, then continues northwards from the periphery of the northeast rim. Attached to the western rim of Fechner is Fechner T, a small, bowl-shaped crater with a relatively high albedo ray system. This satellite crater is surrounded by a blanket of light-hued ejecta that spills across the southwestern half of Fechner's interior floor. The crater rim of Fechner is relatively worn and eroded, with the eastern half of the rim reshaped due to the valley and proximity to Planck. The interior floor is marked by several small craters. The crater is named after Gustav Theodor Fechner, a German physicist, psychologist, and philosopher (1801-1887 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grotrian (crater)
Grotrian is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It lies to the north of the huge walled plain Schrödinger, within the radius of that formation's outer blanket of ejecta. The long Vallis Planck Vallis Planck is a long, linear valley located on the far side of the Moon. It is oriented radially to the huge Schrödinger basin, and was most likely formed by that impact. The selenographic coordinates of this feature are , and it has a length ... formation begins just to the north of Grotrian, and continues to the north-northwest towards Pikel'ner. The outer wall of this crater forms a very nearly circular shape, with the smaller crater Hawke across the southern rim breaking up the symmetry. The interior surfaces form relatively smooth slopes that continue down to the material deposited across the bottom. Apart from Hawke and a small crater on the northern edge of the rim, this formation has not been significantly eroded b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vallis Planck
Vallis Planck is a long, linear valley located on the far side of the Moon. It is oriented radially to the huge Schrödinger basin, and was most likely formed by that impact. The selenographic coordinates of this feature are , and it has a length of 451 km. This cleft in the surface crosses the western part of the huge walled plain Planck, and it was named after that feature (which has an eponym of Max Planck Max Karl Ernst Ludwig Planck (, ; 23 April 1858 – 4 October 1947) was a German theoretical physicist whose discovery of energy quanta won him the Nobel Prize in Physics in 1918. Planck made many substantial contributions to theoretical p ...). The southern edge closest to Schrödinger begins near the northeastern outer rampart of the crater Grotrian. It then continues to the north-northwest, where it suffers a disruption where it crosses the crater Fechner. The remainder of the feature continues to the northwestern outer rim of the walled plain Planck, unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
