Rodin (crater)
Rodin is an impact crater on the planet Mercury, 230 kilometers in diameter. The rim is even and circular, except where it is broken in two places toward the north and south. It is named for the French sculptor Auguste Rodin. Its name was approved by the International Astronomical Union in 1976. Rodin is one of 110 peak ring basins on Mercury.Chapman, C. R., Baker, D. M.

James Turrell
James Turrell (born May 6, 1943) is an American artist known for his work within the Light and Space movement. Much of Turrell's career has been devoted to a still-unfinished work, ''Roden Crater'', a natural cinder cone crater located outside Flagstaff, Arizona, that he is turning into a massive naked-eye observatory; and for his series of skyspaces, enclosed spaces that frame the sky. Turrell was a MacArthur Fellow in 1984. Background James Turrell was born in Los Angeles, California. His father, Archibald Milton Turrell,Adcock, Craig, ''James Turrell: The Art of Light and Space'', Berkeley/Los Angeles/Oxford : University of California Press, 1990, p. 2. was an aeronautical engineer and educator. His mother, Margaret Hodges Turrell, trained as a medical doctor and later worked in the Peace Corps. His parents were Quakers. Turrell obtained a pilot's license when he was 16 years old. Later, registered as a conscientious objector during the Vietnam War, he flew Buddhist monk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Art
Land art, variously known as Earth art, environmental art, and Earthworks, is an art movement that emerged in the 1960s and 1970s, largely associated with Great Britain and the United StatesArt in the modern era: A guide to styles, schools, & movements. Abrams, 2002. (U.S. edition of Styles, Schools and Movements, by Amy Dempsey) but that also includes examples from many countries. As a trend, "land art" expanded boundaries of art by the materials used and the siting of the works. The materials used were often the materials of the Earth, including the soil, rocks, vegetation, and water found on-site, and the sites of the works were often distant from population centers. Though sometimes fairly inaccessible, photo documentation was commonly brought back to the urban art gallery.http://www.land-arts.com Land art. Concerns of the art mov ...

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] |
Auguste Rodin
François Auguste René Rodin (12 November 184017 November 1917) was a French sculptor, generally considered the founder of modern sculpture. He was schooled traditionally and took a craftsman-like approach to his work. Rodin possessed a unique ability to model a complex, turbulent, and deeply pocketed surface in clay. He is known for such sculptures as ''The Thinker'', ''Monument to Balzac'', '' The Kiss'', ''The Burghers of Calais'', and ''The Gates of Hell''. Many of Rodin's most notable sculptures were criticized, as they clashed with predominant figurative sculpture traditions in which works were decorative, formulaic, or highly thematic. Rodin's most original work departed from traditional themes of mythology and allegory. He modeled the human body with naturalism, and his sculptures celebrate individual character and physicality. Although Rodin was sensitive to the controversy surrounding his work, he refused to change his style, and his continued output brought increas ...

Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

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] |
International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 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. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peak Ring
A peak ring crater is a type of complex crater, which is different from a multi-ringed basin or central-peak crater. A central peak is not seen; instead, a roughly circular ring or plateau, possibly discontinuous, surrounds the crater's center, with the crater rim still farther out from the center. Formation The rings form by different processes, and inner rings may not be formed by the same processes as outer rings.Geology Pagewww.geologypage.com/2016/10/research-helps-explain-formation-ringed-crater-moon.html accessdate: February 5, 2017 It has long been the view that peak rings are formed in the stage subsequent to central peak formation in craters. The central peaks of craters are believed to originate from hydrodynamic flow of material lifted by inward-collapsing crater walls, while impact-shattered rock debris is briefly turned to fluid by strong vibrations that develop during crater formation. The peak-ring structure of Chicxulub crater was probably formed as inward-co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abu Nuwas (crater)
Abu Nuwas is an impact crater on the planet Mercury, 116 kilometers in diameter. It is located at 17.4°N, 20.4°W. It is named after the Arab poet Abu Nuwas, and its name was approved by the International Astronomical Union in 1976. There is small central peak in the center of the floor of Abu Nuwas, and bright features known as hollows are present near the peak. To the north of Abu Nuwas are the craters Ts'ai Wen-Chi and Rodin. To the southwest is the crater Molière, and the crater Aśvaghosa can be found toward the south.''NASA World Wind NASA WorldWind is an open-source (released under the NOSA license and the Apache 2.0 license) virtual globe.
