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. Geologic map units are described and classified on the basis of morphology, texture, and albedo, and they are assigned relative ages based on stratigraphic relations and on visual comparisons of the density of superposed craters. Crater ages are established by relative freshness of appearance, as indicated by topographic sharpness of their rim crests and degree of preservation of interior and exterior features such as crater floors, walls, and ejecta aprons. Generally, topography appears highly subdued because of the sun angle, and boundaries between map

  • El quadrangle Beethoven és un dels 15 quadrangles definits del reticulat cartogràfic adoptat de la Unió Astronòmica Internacional per Mercuri. Comprén la part de la superfície de Mercuri entre els 25° S - 25° N de latitud i entre els 72° - 144° longitud O i és identificat amb el codi H-7. El cràter Beethoven és l'estructura geològica present al seu interior triada com a epònim pel mateix quadrangle. Aquesta denominació ha estat adoptada el 1976, després que la missió Mariner 10 disposara de les primeres imatges de la superfície de Mercuri. Abans s'anomenava quadrangle de Solitudo Lycaonis, nom de la característica d'albedo que havia estat històricament identificada en aquesta part de la superfície. Durant els tres de Mercuri es va obtenir un cartografia parcial de la seva superfície. Després de la missió MESSENGER es va poder completar el mapa i millorar el detall de la part ja coneguda. La regió és caracteritzada per alguns sistemes de marques radials i per nombrosos cràters. (ca)
  • 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. Geologic map units are described and classified on the basis of morphology, texture, and albedo, and they are assigned relative ages based on stratigraphic relations and on visual comparisons of the density of superposed craters. Crater ages are established by relative freshness of appearance, as indicated by topographic sharpness of their rim crests and degree of preservation of interior and exterior features such as crater floors, walls, and ejecta aprons. Generally, topography appears highly subdued because of the sun angle, and boundaries between map units are not clearly defined. Impact craters larger than about 250 km are referred to as basins. Unlike many basins on the Moon, however, the two obvious basins in the quadrangle, Beethoven (610 km in diameter) and Raphael (320 km in diameter), are not multiringed, whereas well-developed rings encircle many craters of lesser diameters. Remnant ejecta blankets around parts of the Beethoven and Raphael basins are subdued in appearance and their margins poorly defined in places. However, where they can be recognized, these extensive aprons allow a generalized regional stratigraphic sequence to be determined. A third basin, extremely subdued but probable, is centered at latitude 0°, longitude 130°. Tolstoj quadrangle is to the west of Beethoven quadrangle, and Kuiper quadrangle is to the east. Shakespeare quadrangle and Victoria quadrangle are to the northwest and northeast, and Michelangelo quadrangle and Discovery quadrangle are to the southwest and southeast. (en)
  • La maglia Beethoven è una delle 15 maglie definite dal reticolato cartografico adottato dall'Unione Astronomica Internazionale per Mercurio. Comprende la porzione della superficie di Mercurio posta in latitudine tra i 22° N e i 22° S e in longitudine tra i 72° W e i 144° W ed è identificata con il codice H-7. Il cratere Beethoven è la struttura geologica presente al suo interno scelta come eponimo per la maglia stessa. Questa denominazione è stata adottata nel 1976, dopo che la missione Mariner 10 rese disponibili le prime immagini della superficie di Mercurio. Prima di allora si chiamava maglia di Solitudo Lycaonis dal nome dell'omonima albedo che era stata storicamente individuata in questa porzione della superficie. Durante i tre sorvoli ravvicinati di Mercurio si ottenne una cartografia parziale della sua superficie. Dopo la missione MESSENGER si poté completare la mappa e migliorare il dettaglio della parte già nota. La regione è caratterizzata da alcune raggiere e da numerosi crateri.
