Matabei (crater)
Matabei is an impact crater on Mercury. It has a set of dark rays. Dark rays are rare on Mercury, but other occurrences have been identified, such as at Mozart crater. Mozart crater is interpreted to have excavated dark material from depth during the impact event, creating dark streamers. The dark rays from Matabei may have a similar origin. Matabei was named by the IAU in 2009 after Japanese painter Iwasa Matabei. To the northeast of Matabei is the crater Pigalle. To the south is Rilke, and to the northwest is Guido d'Arezzo.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iwasa Matabei
Iwasa Matabei ( ja, 岩佐 又兵衛, translit=Iwasa Matabē; original name Araki Katsumochi 1578 – July 20, 1650) was a Japanese artist of the early Tokugawa period, who specialized in genre scenes of historical events and illustrations of classical Chinese and Japanese literature, as well as portraits. He was the son of Araki Murashige, a prominent ''daimyō'' of the Sengoku period who had been made to commit suicide, leaving Matabei to be raised with his mother's family name, Iwasa. Matabei's work was noted for its distinctive figures, with large heads and delicately drawn features, and he was effective both in colour and monochrome ink-wash painting, using an individual brush technique combining Tosa and Kanō elements. Although trained by Kanō Naizen of the Kanō school, he was more influenced by the traditions of the Tosa school, and signed a late series of portraits of the Thirty-six Poetry Immortals (1640) commissioned by the ''shōgun'' Tokugawa Iemitsu for a ...

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 ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ray Systems
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 the surrounding surface. More ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mozart (crater)
Mozart is a crater on Mercury, named by the IAU in 1976 after Austrian composer Wolfgang Amadeus Mozart. The arc of dark hills visible on the crater's floor represents remnants of a central peak ring. Mozart 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. Impact Cratering of Mercury. In ''Mercury: The View After MESSENGER'' edited by Sean C. Solomon, Larry R. Nittler, and Brian J. Anderson. Cambridge Planetary Science. Chapter 9. A close inspection of the area around Mozart crater shows many long chains of secondary craters, formed by impact of material thrown out during the formation of the main crater. Mozart crater is located just south of the Caloris basin. To the southeast is Tir Planitia.
