Landau (crater)
Landau is a large lunar impact crater that is located in the northern hemisphere on the far side of the Moon. It was named after physicist Lev Landau. The crater Wegener is attached to the northeastern rim. Attached to the southeastern rim is Frost. The outer rim of Landau is heavily eroded and modified by subsequent impacts. The most notable of these is Wood, which overlays the northwest rim. Much of the floor is hilly and irregular, with only the northeast quadrant being somewhat level. There are multiple small craters and craterlets in the floor. The most intact section of the rim is in the southwest, although this is now little more than a low ridge line. Landau lies at the approximate margin of the Coulomb-Sarton Basin, a 530 km wide impact crater of Pre-Nectarian The pre-Nectarian period of the lunar geologic timescale runs from 4.533 billion years ago (the time of the initial formation of the Moon) to 3.920 billion years ago, when the Nectaris Basin was formed by a ...

Lev Davidovich Landau
Lev Davidovich Landau (russian: Лев Дави́дович Ланда́у; 22 January 1908 – 1 April 1968) was a Soviet- Azerbaijani physicist of Jewish descent who made fundamental contributions to many areas of theoretical physics. His accomplishments include the independent co-discovery of the density matrix method in quantum mechanics (alongside John von Neumann), the quantum mechanical theory of diamagnetism, the theory of superfluidity, the theory of second-order phase transitions, the Ginzburg–Landau theory of superconductivity, the theory of Fermi liquids, the explanation of Landau damping in plasma physics, the Landau pole in quantum electrodynamics, the two-component theory of neutrinos, and Landau's equations for ''S'' matrix singularities. He received the 1962 Nobel Prize in Physics for his development of a mathematical theory of superfluidity that accounts for the properties of liquid helium II at a temperature below (). Life Early years Landau was born o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood (crater)
Wood is a lunar impact crater that lies entirely within the interior of the much larger walled plain Landau, on the far side of Moon. Wood is situated along the northwestern part of the floor of Landau, and shares a common northwestern rim with the larger impact. The inner wall of the northwest rim extends inward about halfway toward the crater midpoint, where there is a central peak. The rim of Wood is somewhat worn and uneven, with a small crater laid across the southwest section. The surviving interior floor is nearly level and is marked only by a few tiny craterlets. Wood lies at the approximate margin of the Coulomb-Sarton Basin, a 530 km wide impact crater of Pre-Nectarian age. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Wood. Wood S is adjacent to Wood on the west side. Wood T is a small crater northwest of Wood S, which has a bright ray system A ray syste ...

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 ...

Pre-Nectarian
The pre-Nectarian period of the lunar geologic timescale runs from 4.533 billion years ago (the time of the initial formation of the Moon) to 3.920 billion years ago, when the Nectaris Basin was formed by a large impact. It is followed by the Nectarian period. Description Pre-Nectarian rocks are rare in the lunar sample suite; they are mostly composed of lunar highlands material which have been heavily churned, brecciated, and thermally affected by subsequent impacts, particularly during the Heavy Bombardment Eon (HBE; a period of 0.6-1 Gy from the formation of the Moon until at least the formation of the Imbrium Basin ~3.9 Ga, or even later with the formation of Orientalis Basin) that marks the approximate beginning of the Nectarian period. The primary pre-Nectarian lunar highland material is dominated by the rock type anorthosite, which suggests that the early stage of lunar crustal formation occurred via mineral crystallization of a global magma ocean. This geologic period has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coulomb-Sarton Basin
The Coulomb-Sarton Basin is a Pre-Nectarian impact basin on the far side of the moon. It is named after the crater Coulomb northeast of the center of the basin and the smaller crater Sarton just south of the center. The basin is not obvious on the lunar surface. There are only small fragments of inner rings and a rim, and the most indicative topographic feature is a smooth, low plain at the center. At the center is a mass concentration (mascon), or gravitational high. The mascon was first identified by Doppler tracking of the Lunar Prospector spacecraft. The existence of the basin was confirmed by the GRAIL spacecraft. Other craters within the basin include Weber and Kramers. At the approximate margin of the basin are Dyson, Ellison, Stefan, Wegener, Wood, Landau, and Gullstrand. The large crater Birkhoff is to the northwest.

Frost (crater)
Frost is a lunar impact crater that is attached to the southern rim of the walled plain Landau, and lies on the far side of the Moon. Just to the east is Petropavlovskiy, and to the northeast along the edge of Landau is Razumov. The crater Douglass is located less than a crater diameter to the west-southwest. The outer rim of Frost is eroded, but is overlaid by only one small craterlet along the northeast side. The inner wall is wider and heavier along the northern side where it has been reinforced by the former rim of Landau. The northern part of the interior floor is occupied by two smaller craters, with the larger of the two along the northwest inner wall. The southern part of the floor is relatively level and featureless. Human activity Frost was originally selected as the site of Station 5 for the Apollo 15 lunar surface operations, however astronaut David Scott David Randolph Scott (born June 6, 1932) is an American retired test pilot and NASA astronaut who was ...

Landau Crater 5015 H3
Landau ( pfl, Landach), officially Landau in der Pfalz, is an autonomous (''kreisfrei'') town surrounded by the Südliche Weinstraße ("Southern Wine Route") district of southern Rhineland-Palatinate, Germany. It is a university town (since 1990), a long-standing cultural centre, and a market and shopping town, surrounded by vineyards and wine-growing villages of the Palatinate wine region. Landau lies east of the Palatinate forest, on the German Wine Route. It contains the districts (''Ortsteile'') of Arzheim, Dammheim, Godramstein, Mörlheim, Mörzheim, Nussdorf, Queichheim, and Wollmesheim. History Landau was first mentioned as a settlement in 1106. It was in the possession of the counts of Leiningen-Dagsburg-Landeck, whose arms, differenced by an escutcheon of the Imperial eagle, served as the arms of Landau until 1955. The town was granted a charter in 1274 by King Rudolf I of Germany, who declared the town a Free Imperial Town in 1291; nevertheless Prince-Bishop Emich of S ...

Wegener (lunar Crater)
Wegener is a Lunar craters, lunar impact crater that is located in the Moon's northern hemisphere, about midway between the equator and the north pole. It lies on the Far side (Moon), far side from the Earth, behind the northwestern limb. The southwestern rim of Wegener intrudes slightly into the much larger walled plain Landau (crater), Landau. Attached to the eastern rim is the crater Stefan (crater), Stefan. This crater is in an intermediate stage of impact erosion, with a worn rim and some craters overlapping the edge and inner wall. The rim is generally more eroded in the northern half. A small crater lies across the western inner wall and part of the interior floor. There is a small, cup-shaped craterlet just to the east of this feature. The inner wall is wider in the southern half, leaving some irregularities on the southern half of the floor. The remainder of the interior is a nearly level and featureless plain. Wegener lies at the approximate margin of the Coulomb-Sart ...
