Kertész (crater)
Located in the western edge of Mercury's giant Caloris basin, Kertész crater (named in 2008 for André Kertész, a Hungarian-born American photographer) has some unusual, bright material located on its floor. Sander A sander is a power tool used to smooth surfaces by abrasion with sandpaper. Sanders have a means to attach the sandpaper and a mechanism to move it rapidly contained within a housing with means to handhold it or fix it to a workbench. Woodw ... crater, located in the northwestern edge of Caloris basin, also shows bright material on its floor. Just northeast of Kertész a small crater has very bright rays and ejecta, indicating that the crater is young. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raditladi Quadrangle
The Raditladi quadrangle (geography), quadrangle (H-4) is one of List of quadrangles on Mercury, fifteen quadrangles on Mercury. It runs from 270 to 180° longitude and 20 to 70° latitude. Named after the Raditladi Basin, it was mapped in detail for the first time after ''MESSENGER'' entered orbit around Mercury (planet), Mercury in 2011. It had not been mapped prior to that point because it was one of the six quadrangles that was not illuminated (with the exception of a thin strip of its territory along the eastern border with Shakespeare quadrangle) when ''Mariner 10'' made its flybys in 1974 and 1975. These six quadrangles continued to be known by their list of albedo features on Mercury, albedo feature names, with this one known as the Liguria quadrangle. The Caloris Planitia, Caloris basin is centered in Raditladi quadrangle, though it overlaps significantly with the Tolstoj quadrangle, Tolstoj and Shakespeare quadrangle, Shakespeare quadrangles. The Borealis quadrangle i ... [...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] |
André Kertész
André Kertész (; 2 July 1894 – 28 September 1985), born Andor Kertész (), was a Hungarian-born photographer known for his groundbreaking contributions to photographic composition (visual arts), composition and the photo essay. In the early years of his career, his then-unorthodox camera angles and style prevented his work from gaining wider recognition. Kertész never felt that he had gained the worldwide recognition he deserved. Today he is considered one of the seminal figures of 20th century photography. Expected by his family to work as a stockbroker, Kertész pursued photography independently as an Autodidacticism, autodidact, and his early work was published primarily in magazines, a major market in those years. This continued until much later in his life, when Kertész stopped accepting commissions. He served briefly in World War I and moved to Paris in 1925, then the artistic capital of the world, against the wishes of his family. In Paris he worked for France's fi ...

Caloris Basin
Caloris Planitia is a plain within a large impact basin on Mercury, informally named Caloris, about in diameter. It is one of the largest impact basins in the Solar System. "Calor" is Latin for "heat" and the basin is so-named because the Sun is almost directly overhead every second time Mercury passes perihelion. The crater, discovered in 1974, is surrounded by the Caloris Montes, a ring of mountains approximately tall. Appearance Caloris was discovered on images taken by the '' Mariner 10'' probe in 1974. Its name was suggested by Brian O'Leary, astronaut and member of the ''Mariner 10'' imagery team. It was situated on the terminator—the line dividing the daytime and nighttime hemispheres—at the time the probe passed by, and so half of the crater could not be imaged. Later, on January 15, 2008, one of the first photos of the planet taken by the ''MESSENGER'' probe revealed the crater in its entirety. The basin was initially estimated to be about in diameter, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impact Crater
An impact crater is a depression (geology), depression in the surface of a solid astronomical body formed by the hypervelocity impact event, 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. Impact craters are typically circular, though they can be elliptical in shape or even irregular due to events such as landslides. Impact craters range in size from microscopic craters seen on lunar rocks returned by the Apollo Program to simple bowl-shaped depressions and vast, 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 (planet), Mercury, Callisto (moon), Callisto, Ganymede (moon), Ganymede, and most small moons and asteroids.

Sander (crater)
Sander is a crater on Mercury within Caloris Basin. It has dark walls and bright patches on its floor. Unlike the rays of Bashō crater, the bright areas are not believed to be immature, but they are inherently bright. It is named after the German photographer August Sander August Sander (17 November 1876 – 20 April 1964) was a German portrait photography, portrait and Documentary photography, documentary photographer. His first book ''Face of our Time'' (German: ''Antlitz der Zeit'') was published in 1929. Sande ... (1876–1964). Hollows are present within Sander. A confirmed ''dark spot'' is present in Sander.Zhiyong Xiao, Robert G. Strom, David T. Blewett, Paul K. Byrne, Sean C. Solomon, Scott L. Murchie, Ann L. Sprague, Deborah L.

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?
