Rivera (crater)
Rivera is a crater on Mercury. It has a diameter of 40 kilometers. Its name was suggested by Mexican residents Ricardo Martinez and Arturo Gutierrez, and American residents Rebecca Hare and José Martinez, in a naming contest which was eventually adopted by the International Astronomical Union (IAU) on 2015. Rivera is named for the Mexican poet Diego Rivera. The craters Carolan, Enheduanna, Karsh, and Kulthum were also named as part of the contest. Rivera lies within the vast plain of Borealis Planitia Borealis Planitia is a large plain on Mercury with a smooth floor, thought to be similar to a lunar mare The lunar maria (; singular: mare ) are large, dark, basaltic plains on Earth's Moon, formed by ancient asteroid impacts on the far sid ....

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] |
Borealis Quadrangle
The Borealis quadrangle is a quadrangle on Mercury surrounding the north pole down to 65° latitude. It was mapped in its entirety by the ''MESSENGER'' spacecraft, which orbited the planet from 2008 to 2015, excluding areas of permanent shadow near the north pole. Only approximately 25% of the quadrangle was imaged by the '' Mariner 10'' spacecraft during its flybys in 1974 and 1975. The quadrangle is now called H-1. It contains the Goethe Basin, whose diameter of at least makes it the sixth-largest impact basin observed on Mariner 10 images(Murray and others, 1974; Boyce and Grolier, 1977; Strom, 1977). The west half of the mapped area (between long 100° and 190° W.) is dominated by older craters and by intercrater plains material that lies between and within them. Younger crater materials, intermediate plains material, and small patches of smooth plains material are superposed on all other units. The crater Verdi, in diameter, is the largest of the younger craters. Its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Diego Rivera
Diego María de la Concepción Juan Nepomuceno Estanislao de la Rivera y Barrientos Acosta y Rodríguez, known as Diego Rivera (; December 8, 1886 – November 24, 1957), was a prominent Mexican painter. His large frescoes helped establish the Mexican muralism, mural movement in Mexican art, Mexican and international art. Between 1922 and 1953, Rivera painted murals in, among other places, Mexico City, Chapingo, and Cuernavaca, Mexico; and San Francisco, Detroit, and New York City, United States. In 1931, a retrospective exhibition of his works was held at the Museum of Modern Art in New York; this was before he completed his 27-mural series known as ''Detroit Industry Murals''. Rivera had four wives and numerous children, including at least one natural daughter. His first child and only son died at the age of two. His third wife was fellow Mexican artist Frida Kahlo, with whom he had a volatile relationship that continued until her death. His fourth and final wife was his agen ...

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] |
Carolan (crater)
Carolan is a crater on Mercury. Its name was suggested by an Irishman, Fergal Donnelly, and two Americans, Joseph Brusseau and Deane Morrison, in a naming contest which was eventually adopted by the International Astronomical Union (IAU) on 2015. Carolan is named for the Irish composer and performer Turlough O'Carolan, who lived from 1670 to 1738 C.E. The craters Kulthum, Enheduanna, Karsh, and Rivera were also named as part of the contest. S band radar data from the Arecibo Observatory collected between 1999 and 2005 indicates a radar-bright area along the southern interior of Carolan, which is probably indicative of a water ice deposit, and lies within the permanently shadowed part of the crater.Chabot, N.

Enheduanna (crater)
Enheduanna is a crater on Mercury. It has a diameter of 105 kilometers. Its name was suggested by Gagan Toor from India in a naming contest which was eventually adopted by the International Astronomical Union (IAU) on 2015. Enheduanna is named for the Sumerian poet Enheduanna. The craters Carolan, Kulthum, Karsh, and Rivera were also named as part of the contest. There are irregular depressions at the center of Enheduanna, which are similar to those within Navoi, Lermontov, Scarlatti, and Praxiteles. The depressions resemble those associated with volcanic explosions. The scarp known as Victoria Rupes Victoria Rupes is an escarpment in the Victoria quadrangle of Mercury. The quadrangle was named after this escarpment, and the escarpment itself was named after the ''Victoria'', a ship used on the famous expedition of Ferdinand Magellan.

Karsh (crater)
Karsh is a crater on Mercury. It has a diameter of 58 kilometers. Its name was suggested by American resident Elizabeth Freeman Rosenzweig in a naming contest which was eventually adopted by the International Astronomical Union (IAU) on 2015. Karsh is named for the Armenian-Canadian photographer Yousuf Karsh. The craters Carolan, Enheduanna, Kulthum, and Rivera were also named as part of the contest. Karsh lies on the west rim of the much larger Rembrandt Rembrandt Harmenszoon van Rijn (, ; 15 July 1606 – 4 October 1669), usually simply known as Rembrandt, was a Dutch Golden Age painter, printmaker and draughtsman.
