Van Eyck (crater)
Van Eyck is a 271 km diameter impact basin in the Shakespeare quadrangle of Mercury. It is located at 43.22°N, 159.43°W and is named after the 15th century Flemish painter Jan van Eyck. Its name was adopted by the International Astronomical Union (IAU) in 1979. Van Eyck lies on the southwestern margin of the even-larger Shakespeare basin. The younger Mansur Mansour ( ar, منصور, Manṣūr); also spelled Mounsor, Monsur (Bengali), Mansoor, Manser, Mansur, Mansyur (Indonesian) or Mensur (Turkish), is a male Arabic name that means "He who is victorious", from the Arabic root '' naṣr'' (نصر), m ... crater lies to the northwest of Van Eyck.

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 ...

Jan Van Eyck
Jan van Eyck ( , ; – July 9, 1441) was a painter active in Bruges who was one of the early innovators of what became known as Early Netherlandish painting, and one of the most significant representatives of Early Northern Renaissance art. According to Vasari and other art historians including Ernst Gombrich, he invented oil painting, Gombrich, The Story of Art, page 240 though most now regard that claim as an oversimplification. The surviving records indicate that he was born around 1380 or 1390, most likely in Maaseik (then Maaseyck, hence his name), Limburg, which is located in present-day Belgium. He took employment in The Hague around 1422, when he was already a master painter with workshop assistants, and was employed as painter and ''valet de chambre'' to John III the Pitiless, ruler of the counties of Holland and Hainaut. After John's death in 1425, he was later appointed as court painter to Philip the Good, Duke of Burgundy, and worked in Lille before moving to B ...

Impact Basin
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 erode ...

Shakespeare Quadrangle
The Shakespeare quadrangle is a region of Mercury running from 90 to 180° longitude and 20 to 70° latitude. It is also called Caduceata. The Borealis quadrangle is north of Shakespeare quadrangle. To the west is Raditladi quadrangle, and to the east is Victoria quadrangle. To the southwest is Tolstoj quadrangle, and to the southeast is Beethoven quadrangle. Mariner 10 imaging Prior to the images taken by MESSENGER, the only spacecraft images of Mercury were those taken by the Mariner 10 spacecraft, which made three passes of the planet in 1974–75 (Murray and others, 1974a,b; Strom and others, 1975a). Most images used in mapping the geology of the Shakespeare quadrangle were taken during the near-equatorial first pass, with close encounter or the dark side of the planet. The second, south-polar pass did not image the Shakespeare quadrangle at high resolution. High-resolution images of small areas within the quadrangle were also obtained during the third pass, when the sp ...

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 ...

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 ...

Shakespeare (Mercurian Crater)
Shakespeare is a 370 km diameter impact basin in the Shakespeare quadrangle of Mercury, which is named after this crater. It is located at 48.1°N, 152.3°W and is named after playwright William Shakespeare William Shakespeare ( 26 April 1564 – 23 April 1616) was an English playwright, poet and actor.

Mansur (crater)
Mansur is a crater on Mercury. Its name was adopted by the International Astronomical Union in 1979. Mansur is named for the Indian artist Ustad Mansur Ustad Mansur (flourished 1590-1624) was a seventeenth-century Mughal painter and court artist. He grew up during the reign of Jahangir (r. 1605 - 1627) during which period he excelled at depicting plants and animals. He was the earliest artist t ..., who lived in the 17th century CE. The Mansurian time period on Mercury is named after Mansur crater. The time of its impact does not denote the start of the period, but the crater is an excellent example of a Mansurian crater.
