Bello (crater)
Bello is a crater on Mercury. It has a diameter of 129 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 1976. Bello is named for the Venezuelan poet Andrés Bello, who lived from 1781 to 1865. At the west rim of Bello is a ''dark spot'' of low reflectance material (LRM), closely associated with hollows.Zhiyong Xiao, Robert G. Strom, David T. Blewett, Paul K. Byrne, Sean C.

Beethoven Quadrangle
The Beethoven Quadrangle (geography), quadrangle is located in the equatorial region of Mercury (planet), 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, how ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Andrés Bello
Andrés de Jesús María y José Bello López (; November 29, 1781 – October 15, 1865) was a Venezuelan Humanism, humanist, diplomat, poet, legislator, philosopher, educator and philologist, whose political and literary works constitute an important part of Spanish American culture. Bello is featured on the old 2,000 Venezuelan bolívar and the 20,000 Chilean peso notes. In Caracas, where he was born, Andrés Bello was Simón Bolívar's teacher for a short period of time and participated in efforts that led to Venezuelan War of Independence, Venezuelan independence. As a diplomat for the new independent government that he helped establish, he went with Luis López Méndez and Simón Bolívar on their first diplomatic mission to London. He lived in London from 1810 to 1829. In 1829, Bello went with his family to Chile. He was hired by the Chilean government and made great works in the field of law and humanities. In Santiago he held positions as a senator and a professor, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Astronomical Union
The International Astronomical Union (IAU; , UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded on 28 July 1919 in Brussels, Belgium and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. the Union had 85 national members and 12,734 individual members, spanning 90 countries and territories. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ...

National Aeronautics and Space Act, Established in 1958, it succeeded the National Advisory Committee for Aeronautics (NACA) to give the American space development effort a distinct civilian orientation, emphasizing peaceful applications in space science. It has since led most of America's space exploration programs, including Project Mercury, Project Gemini, the 1968–1972 Apollo program missions, the Skylab space station, and the Space Shuttle. Currently, NASA supports the International Space Station (ISS) along with the Commercial Crew Program and oversees the development of the Orion (spacecraft), Orion spacecraft and the Sp ...

Hollows (Mercury)
Hollows are a landform on the planet Mercury, discovered during the ''MESSENGER'' mission that orbited the planet from 2011 to 2015. Hollows are typically clusters of rimless depressions with flat floors and haloes of bright (high albedo) material surrounding them. Hollows are thought to form by loss of volatiles from the surface by sublimation, caused by the intense solar radiation on the airless planet. They are some of the youngest features on Mercury. Hollows were first observed as bright areas within craters imaged by the Mariner 10 spacecraft in 1974, but the images were not of sufficient resolution to discern any detail. These craters include Balzac, Tyagaraja, Theophanes, Zeami, and Hopper.Dzurisin, D., 1977. Mercurian bright patches: Evidence for physio-chemical alteration of surface material?

Beethoven (crater)
Beethoven is a crater at latitude 20°S, longitude 124°W on Mercury. It is 630 km in diameter and was named after Ludwig van Beethoven. It is the eleventh largest named impact crater in the Solar System and the third largest on Mercury (after Caloris and Rembrandt). Unlike many basins of similar size on the Moon, such as the Orientale Basin, Beethoven is not multi-ringed. Remnant ejecta blankets around parts of the Beethoven are subdued in appearance and their margins poorly defined in places. The crater wall (rim) of Beethoven is buried by its ejecta blanket and by plains materials and is barely visible. The floor of the basin is covered with intermediate smooth plains material, which has the same reflectance as the exterior intermediate terrain. However, there are no wrinkle ridges or graben inside the basin like those in Caloris. Spudis and Prosser have suggested that Beethoven may possibly be late c3 in age or as old as early c2, which means that it is older than t ...
