Motonobu (crater)
Motonobu is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) on August 13, 2024, for the Japanese painter and calligrapher, Kanō Motonobu, who lived from 1476 to 1559. The crater was first imaged by Mariner 10 in 1974. The crater has a ray system, indicating it is a recent impact. Motonobu is to the east of the crater Polygnotus and north of the crater Thākur.

Kanō Motonobu
was a Japanese people, Japanese Japanese painting, painter and Japanese calligraphy, calligrapher. He was a member of the Kanō school of painting. Through his political connections, patronage, organization, and influence he was able to make the Kanō school into what it is today. The system was responsible for the training of a great majority of painters throughout the Edo period (1603–1868). After his death, he was referred to as Kohōgen (古法眼). Family background The Kanō family are presumed to be the descendants from a line of warriors from the Kanō district. The Kanō district is now called Shizuoka Prefecture. The forebear of this family was Kanō Kagenobu. He seems to have been a retainer of the Imagawa family. It has been reported that he painted a picture of Mount Fuji for a visit to the ''shōgun'' Ashikaga Yoshinori in 1432. The Kanō family dominated the painting world from the end of the Muromachi period (1336–1573) to the end of the Edo period (1603–186 ...

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] |
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 ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agencies of the United States government, independent agency of the federal government of the United States, US federal government responsible for the United States's civil list of government space agencies, space program, aeronautics research and outer space, space research. 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 ...

USGS
The United States Geological Survey (USGS), founded as the Geological Survey, is an government agency, agency of the United States Department of the Interior, U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from List of NASA missions, U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous s ... [...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 mission to use a gravity assist from one planet (in this case, Venus) t ...

Ray System
In planetary geology, a ray system comprises radial streaks of fine '' ejecta'' thrown out during the formation of an impact crater, looking somewhat like many thin spokes coming from the hub of a wheel. The rays may extend for lengths up to several times the diameter of their originating crater, and are often accompanied by small secondary craters formed by larger chunks of ejecta. Ray systems have been identified on the Moon, Earth ( Kamil Crater), Mercury, and some moons of the outer planets. Originally it was thought that they existed only on planets or moons lacking an atmosphere, but more recently they have been identified on Mars in infrared images taken from orbit by '' 2001 Mars Odyssey''s thermal imager. Rays appear at visible, and in some cases infrared wavelengths, when ejecta are made of material with different reflectivity (i.e., albedo) or thermal properties from the surface on which they are deposited. Typically, visible rays have a higher albedo than th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polygnotus (crater)
Polygnotus is a crater on Mercury, named by the IAU in 1976, after ancient Greek painter Polygnotus. The crater was first imaged by Mariner 10 in 1974. Polygnotus has a central peak ring which is embayed with smooth plains material, which is very different in texture from the surrounding terrain. It is one of 110 peak ring basins on Mercury.Chapman, C. R., Baker, D. M. H., Barnouin, O. S., Fassett, C. I., Marchie, S., Merline, W. J., Ostrach, L. R., Prockter, L. M., and Strom, R. G., 2018.

Thākur (crater)
Thākur is a crater on Mercury. It has a diameter of . Its name was adopted by the International Astronomical Union (IAU) in 1976. Thākur is named for the Indian writer Rabindranath Tagore. The crater was first imaged by Mariner 10 in 1974. Scarps in the central and southern part of the crater enclose an area that is at a lower elevation than the rest of the crater.
