71Diacria quadrangle — Map of Diacria quadrangle from Mars Orbiter Laser Altimeter (MOLA) data. The highest elevations are red and the lowest are blue Coordinates …
72Beethoven quadrangle — The Beethoven quadrangle is located in the equatorial region of Mercury, in the center of the area imaged by Mariner 10. Most pictures of the quadrangle were obtained at high sun angles as the Mariner 10 spacecraft receded from the planet.… …
73Tolstoj 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. [International… …
74Kuiper 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 and others, 1975), and the small crater Hun Kal… …
75Borealis quadrangle — The Borealis quadrangle is a quadrangle on Mercury surrounding the north pole down to 65° latitude (see also: geography of Mars).It contains the Goethe Basin, whose diameter of at least convert|400|km|abbr=on makes it the sixth largest impact… …
76Victoria quadrangle — The Victoria quadrangle is a region on Mercury from 0 to 90° longitude and 20 to 70 ° latitude. It is designated the H 2 quadrangle, and is also known as Aurora after a large albedo feature.Most of the Victoria quadrangle lies within an area that …
77Discovery quadrangle — Mariner 10 photomosaic The Discovery quadrangle lies within the heavily cratered part of Mercury in a region roughly antipodal to the 1550 km wide Caloris Basin. Like the rest of the heavily cratered part of the planet, the quadrangle contains a… …
78Michelangelo 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… …
79Coprates quadrangle — The Coprates quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Coprates quadrangle is also referred to as MC 18 (Mars Chart 18).[1] The Coprates… …
80Generalized quadrangle — A generalized quadrangle is an incidence structure. A generalized quadrangle is by definition a polar space of rank two. They are the generalized n gons with n=4. They are also precisely the partial geometries pg(s,t,alpha). DefinitionA… …
