Mansart (crater)
Mansart is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 1979. Mansart is named for the French architect Jules Hardouin-Mansart, who lived from 1646 to 1708. To the east of Mansart is Bjornson Bjørnson is a Norwegian surname with the literal meaning "Son of Bjørn".

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] |
Jules Hardouin-Mansart
Jules Hardouin-Mansart (; 16 April 1646 – 11 May 1708) was a French Baroque architect and builder whose major work included the Place des Victoires (1684–1690); Place Vendôme (1690); the domed chapel of Les Invalides (1690), and the Grand Trianon of the Palace of Versailles. His monumental work was designed to glorify the reign of Louis XIV of France. Biography Born Jules Hardouin in Paris in 1646, he studied under his renowned great-uncle François Mansart, one of the originators of the classical tradition in French architecture; Hardouin inherited Mansart's collection of plans and drawings and added Mansart's name to his own in 1668. He began his career as an entrepreneur in building construction, in partnership with his brother Michel, but then decided in 1672 to devote himself entirely to architecture. In 1674 he became one of the group of royal architects working for Louis XIV. His first important project was the Château de Clagny, built for the King's consort, Ma ...

Institute Of Physics Publishing
IOP Publishing (previously Institute of Physics Publishing) is the publishing company of the Institute of Physics. It provides publications through which scientific research is distributed worldwide, including journals, community websites, magazines, conference proceedings and books. The Institute of Physics is a scientific charity devoted to increasing the practice, understanding and application of physics. Any financial surplus earned by IOP Publishing goes to support physics through the activities of the Institute. The main IOP Publishing headquarters is located in Bristol, England, and the North American headquarters is in Philadelphia, United States. It also has regional offices in, Mexico City, Beijing, Tokyo, Moscow, St. Petersburg, and Sydney. It employs over 400 staff. It was the first physics publisher to publish a journal on the internet. In 1994, the journal ''Classical and Quantum Gravity'' was published as a TeX file. In January 1996 the organization launched th ...

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] |
USGS
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency.

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown m ...
