Neruda Quadrangle
The Neruda quadrangle (H-13) is one of fifteen quadrangles on Mercury. It runs from 180 to 270° longitude and -20 to -70° latitude. Named after the Neruda crater, it was mapped in detail for the first time after ''MESSENGER'' entered orbit around Mercury in 2011. It had not been mapped prior to that point because it was one of the six quadrangles that was not illuminated (with the exception of a narrow strip along the eastern border with the Michelangelo quadrangle) when ''Mariner 10'' made its flybys in 1974 and 1975. These six quadrangles continued to be known by their albedo feature names, with this one known as the Solitudo Persephones quadrangle. In addition to Neruda crater, the eastern half of the Rembrandt basin is within the quadrangle. Rembrandt is the second-largest impact basin on Mercury, after Caloris. The western half of Rembrandt is in the Debussy quadrangle. The Bach quadrangle is south of Neruda quadrangle. To the west is Debussy quadrangle, and to ...

List Of Albedo Features On Mercury
This is a list of the albedo features of the planet Mercury as seen by early telescopic observation. Early telescopic observations of Mercury were based on the assumption that Mercury keeps one of its faces permanently turned toward the Sun, through the mechanism of tidal locking. Although this is not true (Mercury rotates three times on its axis for every two revolutions around the Sun), when it is positioned for best viewing from Earth, the amount by which its visible face has rotated from its previous best viewing position is fairly small. A map of Mercury made in the 1910s by astronomer Eugène Michel Antoniadi shows the following albedo features, localized by a grid in which 0° longitude is the (assumed) subsolar meridian. No certain connection has been made between these features and the topographic features viewed on Mercury by the Mariner 10 spacecraft. Mariner 10, however, imaged less than half of Mercury's surface. The names are drawn from Greek mythology, and often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tolstoj Quadrangle
The Tolstoj quadrangle in the equatorial region of Mercury runs from 144 to 216° longitude and -25 to 25° latitude. It was provisionally called "Tir", but renamed after Leo Tolstoy by the International Astronomical Union in 1976. Also called Phaethontias. It contains the southern part of Caloris Planitia, which is the largest and best preserved basin seen by ''Mariner 10''. This basin, about 1550 km in diameter, is surrounded by a discontinuous annulus of ejecta deposits of the Caloris Group that are embayed and covered by broad expanses of smooth plains. The southeast half of the quadrangle is dominated by ancient crater deposits, by nondescript rolling to hummocky plains materials between individual craters, and by isolated patches of nondescript plains. The ancient and degraded Tolstoj multiring basin, about 350 km in diameter, is in the south-central part of the quadrangle. The large, well-preserved crater Mozart (285 km diameter) is a prominent feature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eminescu Quadrangle
The Eminescu quadrangle (H-9) is one of fifteen quadrangles on Mercury. It runs from 216 to 288° longitude and from -25 to 25° latitude. Named after the Eminescu crater, it was mapped in detail for the first time after ''MESSENGER'' entered orbit around Mercury in 2011. It had not been mapped prior to that point because it was one of the six quadrangles that was not illuminated when ''Mariner 10'' made its flybys in 1974 and 1975. These six quadrangles continued to be known by their albedo feature names, with this one known as the Solitudo Criophori quadrangle. An unnamed, highly modified impact basin is thought to exist to the southwest of the Caloris basin (at 6.5° N, 134.8° E). The basin is referred to as ''b40'' in scientific literature and it is primarily recognized on the basis of a ring-shaped set of wrinkle ridges with a diameter of 310 kilometers. The western rim of this basin is named Arquipelago Rupes. Derain quadrangle is to the west of Eminescu quadrangle, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bach Quadrangle
The Bach quadrangle encompasses the south polar part of Mercury poleward of latitude 65° S. It is named after the prominent crater Bach within the quadrangle, which is in turn named after Baroque composer Johann Sebastian Bach. The quadrangle is now called H-15. Adjacent quadrangles to the north of Bach are Discovery quadrangle (0° to 90° W), Michelangelo quadrangle (90° to 180° W), Neruda quadrangle (180° to 270° W), and Debussy quadrangle (270° to 0° W). It is opposite the Borealis quadrangle at the north pole. ''Mariner 10'' photography About half of the region was beyond the terminator during the three ''Mariner 10'' encounters and hence not visible. The entire mapped area was covered by near-vertical photography from the second encounter, and the eastern part, from longitude 15° to about 110°, was covered by oblique photography from the first encounter. No third-encounter images were acquired. The entire visible area may be viewed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Debussy Quadrangle
The Debussy quadrangle (H-14) is one of fifteen quadrangles on Mercury. It runs from 270 to 360° longitude and from -20 to -70° latitude. Named after the Debussy crater, it was mapped in detail for the first time after ''MESSENGER'' entered orbit around Mercury in 2011. It had not been mapped prior to that point because it was one of the six quadrangles that was not illuminated when ''Mariner 10'' made its flybys in 1974 and 1975. These six quadrangles continued to be known by their albedo feature names, with this one known as the Cyllene quadrangle. In addition to the prominent Debussy crater, the western half of the Rembrandt basin is within the quadrangle. Rembrandt is the second-largest impact basin on Mercury, after Caloris. The eastern half of Rembrandt is in the Neruda quadrangle. The Bach quadrangle is south of Debussy quadrangle. To the west is Discovery quadrangle, and to the east is Neruda quadrangle. To the north is Derain quadrangle, and to the northeast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caloris Planitia
Caloris Planitia is a plain within a large impact basin on Mercury, informally named Caloris, about in diameter. It is one of the largest impact basins in the Solar System. "Calor" is Latin for "heat" and the basin is so-named because the Sun is almost directly overhead every second time Mercury passes perihelion. The crater, discovered in 1974, is surrounded by the Caloris Montes, a ring of mountains approximately tall. Appearance Caloris was discovered on images taken by the ''Mariner 10'' probe in 1974. Its name was suggested by Brian O'Leary, astronaut and member of the ''Mariner 10'' imagery team. It was situated on the terminator—the line dividing the daytime and nighttime hemispheres—at the time the probe passed by, and so half of the crater could not be imaged. Later, on January 15, 2008, one of the first photos of the planet taken by the ''MESSENGER'' probe revealed the crater in its entirety. The basin was initially estimated to be about in diameter, though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rembrandt (crater)
Rembrandt is a large impact crater on Mercury. With a diameter of 716 km it is the second-largest impact basin on the planet, after Caloris, and is one of the larger craters in the Solar System. It was discovered by ''MESSENGER'' during its second flyby of Mercury on October 6, 2008. The crater is 3.9 billion years old, and was created during the period of Late Heavy Bombardment. The density and size distribution of impact craters along Rembrandt's rim indicate that it is one of the youngest impact basins on Mercury. The crater is named after Dutch painter Rembrandt Harmenszoon van Rijn. Background Rembrandt was discovered in the images taken by the ''MESSENGER'' spacecraft during its second flyby of Mercury on October 6, 2008.. Seimages/ref> The crater is situated in the southern hemisphere of the planet at the latitude of about −33°. It is named after famous Dutch painter Rembrandt Harmenszoon van Rijn (1606–1669).

Mariner 10
''Mariner 10'' was an American Robotic spacecraft, robotic space probe launched by NASA on 3 November 1973, to fly by the planets Mercury (planet), Mercury and Venus. It was the first spacecraft to perform flybys of multiple planets. ''Mariner 10'' was launched approximately two years after ''Mariner 9'' and was the last spacecraft in the Mariner program. (Mariner 11 and Mariner 12 were allocated to the Voyager program and redesignated ''Voyager 1'' and ''Voyager 2''.) The mission objectives were to measure Mercury's environment, atmosphere, surface, and body characteristics and to make similar investigations of Venus. Secondary objectives were to perform experiments in the interplanetary medium and to obtain experience with a dual-planet gravity assist mission. ''Mariner 10''s science team was led by Bruce C. Murray at the Jet Propulsion Laboratory. Design and trajectory ''Mariner 10'' was the first mission to use a gravity assist from one planet (in this case, Venus) t ...

Michelangelo Quadrangle
The Michelangelo quadrangle is in the southern hemisphere of the planet Mercury, where the imaged part is heavily cratered terrain that has been strongly influenced by the presence of multiring basins. At least four such basins, now nearly obliterated, have largely controlled the distribution of plains materials and structural trends in the map area. Many craters, interpreted to be of impact origin, display a spectrum of modification styles and degradation states. The interaction between basins, craters, and plains in this quadrangle provides important clues to geologic processes that have formed the morphology of the mercurian surface. Several low-albedo features are evident in Earth-based views of the Michelangelo quadrangle, but these features do not appear to correlate directly with any mapped terrain unit. Solitudo Promethei may correspond to a deposit of plains materials centered at –58°, 135°, and Solitudo Martis may correspond to similar materials at –30° to ...

Mercury (planet)
Mercury is the first planet from the Sun. It is a rocky planet with a trace atmosphere. While it is the List of Solar System objects by size, smallest and least massive planet of the Solar System, its surface gravity is slightly higher than that of Mars. The surface of Mercury is similar to Earth's Moon, heavily Impact crater, cratered, with expansive rupes system, generated from thrust faults, and bright ray systems, formed by ejecta. Its largest crater, Caloris Planitia, has a diameter of , which is about one-third the diameter of the planet (). Being the most inferior planet, inferior orbiting planet it appears in Earth's sky, always close to the Sun, either as a "morning star" or an "evening star". It stays most of the time the closest to all other planets and is the planet with the highest delta-v needed to travel to from all other planets of the Solar System. Mercury's sidereal year (88.0 Earth days) and sidereal day (58.65 Earth days) are in a 3:2 ratio. This relation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
