Derain Quadrangle
The Derain quadrangle (H-10) is one of fifteen quadrangles on Mercury. It runs from 288° to 360° west longitude and from 22° S to 22° N latitude. Named after the Derain 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 Pieria quadrangle. The hypothetical Skinakas Basin was thought to exist on the west side of the quadrangle, but MESSENGER images did not confirm its existence. The large Lennon-Picasso Basin covers much of the eastern part of the quadrangle. Kuiper quadrangle is to the west of Derain quadrangle, and Eminescu quadrangle is to the east. Hokusai quadrangle is to the north, and Debussy quadrangle The Debussy quadrangle (H-14) is o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quadrangle (geography)
A "quadrangle" is a topographic map produced by the United States Geological Survey (USGS) covering the United States. The maps are usually named after local physiographic features. The shorthand "quad" is also used, especially with the name of the map; for example, "the Ranger Creek, Texas quad". From approximately 1947-1992, the USGS produced the 7.5 minute series, with each map covering an area one-quarter of the older 15-minute quad series, which it replaced. A 7.5 minute quadrangle map covers an area of . Both map series were produced via photogrammetric analysis of aerial photography using stereoplotters supplemented by field surveys. These maps employ the 1927 North American Datum (NAD27); conversion or a change in settings is necessary when using a GPS which by default employ the WGS84 geodetic datum. Beginning in 2009, the USGS made available digital versions of 7.5 minute quadrangle maps based on GIS data that use the NAD83 datum, which is typically within one meter of ...

List Of Quadrangles On Mercury
The surface of the planet Mercury has been divided into fifteen quadrangles, designated H-1 to H-15 (the 'H' stands for Hermes, the Greek equivalent of Mercury). The quadrangles are named for prominent surface features visible within each area. The quadrangles were initially named for albedo features, as these were the most prominent features visible before mapping was carried out by spacecraft. The mapping carried out with the images obtained by the '' Mariner 10'' flybys in 1974 and 1975 led to nine of the quadrangles being renamed for newly mapped prominent features. The remaining six quadrangles were completely unmapped by ''Mariner 10'' and were still referred to by their albedo feature names. Following the arrival of '' MESSENGER'' in orbit in 2011, these six quadrangles were mapped and renamed. The base mosaic used in the new maps was produced with orbital images by the MESSENGER Team and released by NASA’s Planetary Data System on March 8, 2013. This global mosaic includ ...

Derain (crater)
Derain is a crater on Mercury named after André Derain, a French artist, painter, sculptor and co-founder of Fauvism with Henri Matisse. It has uncommonly dark material within and surrounding the crater. The material is darker than the neighboring terrain such that this crater is easily identified even in a distant global image of Mercury. The dark halo may be material with a mineralogical composition different from the majority of Mercury's visible surface. Craters with similar dark material on or near their rims were seen on the floor of the Caloris basin during ''MESSENGER''’s first flyby. Derain is one of 110 peak ring basins on Mercury. The larger and older crater Ellington is to the southeast of Derain. Both Derain and Ellington lie within a much older, 730-km-diameter, unnamed crater (referred to as b36).Chapman, C.

MESSENGER
''MESSENGER'' was a NASA robotic space probe that orbited the planet Mercury between 2011 and 2015, studying Mercury's chemical composition, geology, and magnetic field. The name is a backronym for "Mercury Surface, Space Environment, Geochemistry, and Ranging", and a reference to the messenger god Mercury from Roman mythology. ''MESSENGER'' was launched aboard a Delta II rocket in August 2004. Its path involved a complex series of flybys – the spacecraft flew by Earth once, Venus twice, and Mercury itself three times, allowing it to decelerate relative to Mercury using minimal fuel. During its first flyby of Mercury in January 2008, ''MESSENGER'' became the second mission, after Mariner 10 in 1975, to reach Mercury. ''MESSENGER'' entered orbit around Mercury on March 18, 2011, becoming the first spacecraft to do so. It successfully completed its primary mission in 2012. Following two mission extensions, the spacecraft used the last of its maneuvering propellant to deo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercury (planet)
Mercury is the smallest planet in the Solar System and the closest to the Sun. Its orbit around the Sun takes 87.97 Earth days, the shortest of all the Sun's planets. It is named after the Roman god ' ( Mercury), god of commerce, messenger of the gods, and mediator between gods and mortals, corresponding to the Greek god Hermes (). Like Venus, Mercury orbits the Sun within Earth's orbit as an inferior planet, and its apparent distance from the Sun as viewed from Earth never exceeds 28°. This proximity to the Sun means the planet can only be seen near the western horizon after sunset or the eastern horizon before sunrise, usually in twilight. At this time, it may appear as a bright star-like object, but is more difficult to observe than Venus. From Earth, the planet telescopically displays the complete range of phases, similar to Venus and the Moon, which recurs over its synodic period of approximately 116 days. The synodic proximity of Mercury to Earth makes Mercury most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 spacecraft to make use of an interplanetary gravitational slingshot ...

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 of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skinakas (hypothetical Basin)
The Skinakas basin is the informal name given to a structure on mercury (planet), Mercury that appeared to be an extremely large impact basin. The limited-resolution images available showed a double-ringed structure, with the inner ring having a diameter of around 1600 km, which would have made it one of the largest impact basins in the Solar System. It appeared to be even larger than the Caloris Planitia, Caloris basin on Mercury, which has been known since the ''Mariner 10'' flybys of that planet. The part of the outer ring that was imaged appeared to correspond to a diameter of around 2300 km. The basin was supposedly centered at about and lay on the hemisphere of Mercury that was not imaged by ''Mariner 10''. This place is situated near an List of albedo features on Mercury, albedo feature Solitudo Aphrodites (). In 2001, it was observed and imaged by ALPO (Association of Lunar and Planetary Observers) members. But it was followed by L. Ksanfomality from lucky imagi ...

Lennon-Picasso Basin
The Lennon-Picasso Basin is an ancient (Pre- Tolstojan) impact basin on Mercury, discovered from topographic mapping of the surface by the MESSENGER spacecraft. It is approximately 1450 km in diameter and spans the region between Picasso crater on the north rim to Lennon crater on the south rim, and the crater Holst is near the center. The basin is heavily eroded by subsequent impacts and is not obvious on the surface. A topographic low is present near the center, and scarps representing a remnant of the eastern basin rim are intact. The scarps include the highest point on the planet.Denevi, B. W., Ernst, C.

Kuiper Quadrangle
The Kuiper quadrangle, located in a heavily cratered region of Mercury, includes the young, 55-km-diameter crater Kuiper (11° S., 31.5° ), which has the highest albedo recorded on the planet,Hapke, Bruce, Danielson, G. E., Jr., Klaasen, Kenneth, and Wilson, Lionel, 1975, Photometric observations of Mercury from Mariner 10: ''Journal of Geophysical Research'', v. 80, no. 17, pp. 2431–2443. and the small crater Hun Kal (0.6° S., 20.0° ), which is the principal reference point for Mercurian longitude (Davies and Batson, 1975). Impact craters and basins, their numerous secondary craters, and heavily to lightly cratered plains are the characteristic landforms of the region. At least six multiringed basins ranging from 150 km to 440 km in diameter are present. Inasmuch as multiringed basins occur widely on that part of Mercury photographed by '' Mariner 10'', as well as on the Moon and Mars, they offer a potentially valuable basis for comparison between these planetary b ...
