Eötvös (crater)
Eötvös is the remains of a lunar impact crater on the far side of the Moon. It lies to the north-northwest of the walled plain Roche, and east-southeast of the equally ruined Bolyai. Only the northwestern section of the crater's rim survives, the remainder now forming a battered, uneven circular rise. The rim is nearly non-existent along the southeast where it joins an uneven plain reaching the rim of Roche. Small craters lie along the rim to the northeast and one to the southwest. The interior floor is relatively level, but marked by a number of small craterlets as well as palimpsest In textual studies, a palimpsest () is a manuscript page, either from a scroll or a book, from which the text has been scraped or washed off in preparation for reuse in the form of another document. Parchment was made of lamb, calf, or kid ski ...s, meaning circular rises in the surface that are now scarcely recognizable as craters. Satellite craters By convention these features are ident ...

Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric Polar orbit, 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 LCROSS, 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. ...

Loránd Eötvös
Baron Loránd Eötvös de Vásárosnamény (or simply Loránd Eötvös ; ; ; 27 July 1848 – 8 April 1919), also called Baron Roland von Eötvös in English literature, was a Hungarian physicist. He is remembered today largely for his work on gravitation and surface tension, and the invention of the torsion pendulum. In addition to Eötvös Loránd University and the Eötvös Loránd Institute of Geophysics in Hungary, the Eötvös crater on the Moon, the asteroid 12301 Eötvös and the mineral lorándite also bear his name, as well as a peak (Cima Eotvos) in the Dolomites. Life Born in 1848, the year of the Hungarian revolution, Eötvös was the son of the Baron József Eötvös de Vásárosnamény (1813–1871), a well-known poet, writer, and liberal politician, who was cabinet minister at the time, and played an important part in 19th century Hungarian intellectual and political life. His mother was the Hungarian noble lady Agnes Rosty de Barkócz (1825–1913), m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lunar Craters
Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, all of which were formed by impacts. The International Astronomical Union currently recognizes 9,137 craters, of which 1,675 have been dated. History The word ''crater'' was adopted from the Greek language, Greek word for "vessel" (, a Greek vessel used to mix wine and water). Galileo built his refracting telescope, first telescope in late 1609, and turned it to the Moon for the first time on November 30, 1609. He discovered that, contrary to general opinion at that time, the Moon was not a perfect sphere, but had both mountains and cup-like depressions. These were named craters by Johann Hieronymus Schröter (1791), extending its previous use with volcanoes. Robert Hooke in ''Micrographia'' (1665) proposed two hypotheses for lunar crater formation: one, that the craters were caused by projectile bombardment from space, the other, that they were the products of subterranean lunar volcanism. ...

Impact Crater
An impact crater is a depression (geology), depression in the surface of a solid astronomical body formed by the hypervelocity impact event, impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Impact craters are typically circular, though they can be elliptical in shape or even irregular due to events such as landslides. Impact craters range in size from microscopic craters seen on lunar rocks returned by the Apollo Program to simple bowl-shaped depressions and vast, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury (planet), Mercury, Callisto (moon), Callisto, Ganymede (moon), Ganymede, and most small moons and asteroids. On other planet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Far Side Of The Moon
The far side of the Moon is the hemisphere of the Moon that is facing away from Earth, the opposite hemisphere is the near side. It always has the same surface oriented away from Earth because of synchronous rotation in the Moon's orbit. Compared to the near side, the far side's terrain is rugged, with a multitude of impact craters and relatively few flat and dark lunar maria ("seas"), giving it an appearance closer to other barren places in the Solar System such as Mercury and Callisto. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. The hemisphere has sometimes been called the "Dark side of the Moon", where "dark" means "unknown" instead of "lacking sunlight" each location on the Moon experiences two weeks of sunlight while the opposite location experiences night. About 18 percent of the far side is occasionally visible from Earth due to oscillation and to libration. The remaining 82 percent remained unobserved until 1959, when ...

Roche (crater)
Roche is a large crater on the far side of the Moon from the Earth. The prominent crater Pauli lies across the southern rim of Roche, and the outer rampart of Pauli covers a portion of Roche's interior floor. To the north-northwest of Roche is the crater Eötvös, and just to the west-northwest lies Rosseland. The western rim of Roche has been somewhat distorted and straightened. The rim as a whole is worn and eroded, with multiple tiny craterlets marking the surface. The satellite crater Roche B lies across the northeastern inner wall. The interior floor of Roche is relatively level, but is also marked by several small and tiny craterlets. A grouping of these craters lies near the midpoint. Just to the northwest of this grouping is a bright patch of high-albedo material. Sections of the floor along the north-northwestern side have a lower albedo than elsewhere, usually an indication of basaltic-lava flows similar to what fills the lunar maria. The extent of this patch may a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolyai (crater)
Bolyai is an old Lunar craters, lunar impact crater that is located in the southern sphere, hemisphere on the far side of the Moon. To the southeast of Bolyai is the crater Eötvös (crater), Eötvös, and to the north is Neujmin (crater), Neujmin. It is named after the 19th century Hungarian mathematician János Bolyai. This crater has been heavily eroded and worn by subsequent impacts, leaving only a deformed remnant of the original rim that is overlaid by a multitude of lesser craters. The most notable of these is Bolyai D along the northeast rim and Bolyai W to the northwest. The latter is actually a formation of multiply overlapping craters. The interior of the crater is relatively level, but rough in places due to impacts that have reshaped the surface. Near the rounded central peak, and from there towards the northern rim, is a section of floor that has been resurfaced by lava flows. This area is smoother than the remainder of the floor, and has a lower albedo, giving it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palimpsest
In textual studies, a palimpsest () is a manuscript page, either from a scroll or a book, from which the text has been scraped or washed off in preparation for reuse in the form of another document. Parchment was made of lamb, calf, or kid skin and was expensive and not readily available, so, in the interest of economy, a page was often re-used by scraping off the previous writing. In colloquial usage, the term ''palimpsest'' is also used in architecture, archaeology and geomorphology to denote an object made or worked upon for one purpose and later reused for another; for example, a monumental brass the reverse blank side of which has been re-engraved. Etymology The word ''palimpsest'' derives , which derives from (), a compound word that describes the process: "The original writing was scraped and washed off, the surface resmoothed, and the new literary material written on the salvaged material." The Ancient Greeks used wax-coated tablets to write on with a stylus, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
