Futabatei (crater)
Futabatei is a crater on Mercury. It has a diameter of 57 kilometers. Its name was adopted by the International Astronomical Union in 1976. Futabatei is named for the Japanese novelist Futabatei Shimei, who lived from 1864 to 1909. Futabatei is one of the largest craters of the Kuiperian system on Mercury. The largest is Bartók crater.Denevi, B. W., Ernst, C. M., Prockter, L. M., and Robinson, M. S., 2018. The Geologic History of Mercury. In ''Mercury: The View After MESSENGER'' edited by Sean C.

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] |
Futabatei Shimei
was a Japanese writer, translator, and literary critic. His writings are in the realist style popular in the mid to late 19th century. His work '' The Drifting Cloud'' (''Ukigumo'', 1887) is widely regarded as Japan's first modern novel. Biography Futabatei was born Hasegawa Tatsunosuke in Edo (now Tokyo). After quitting his studies at the Russian language department at the Tokyo Foreign Language School in protest over administrative restructuring, Futabatei published the literary criticism ''Shōsetsu Sōron'' at the encouragement of the critic and author Tsubouchi Shōyō in 1886. Futabatei's first novel '' Ukigumo'' is often said to be unfinished, but its realist style strongly influenced fellow authors in his day. Futabatei was accomplished in Russian and translated the work of Ivan Turgenev and other Russian realists into Japanese. In 1902, he learned Esperanto in Russia. Returning to Japan in 1906, he published the first Japanese-Esperanto instruction book ''Sekaig ... [...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] |
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] |
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 ...

Geology Of Mercury
The geology of Mercury is the scientific study of the surface, crust, and interior of the planet Mercury. It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of terrestrial geology. In planetary science, the term ''geology'' is used in its broadest sense to mean the study of the solid parts of planets and moons. The term incorporates aspects of geophysics, geochemistry, mineralogy, geodesy, and cartography. Historically, Mercury has been the least understood of all the terrestrial planets in the Solar System. This stems largely from its proximity to the Sun which makes reaching it with spacecraft technically challenging and Earth-based observations difficult. For decades, the principal source of geologic information about Mercury came from the 2,700 images taken by the Mariner 10 spacecraft during three flybys of the planet from 1974 to 1975. These images covered about 45% of the planet’s surface, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bartók (crater)
Bartók is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 1979. Bartók is named for the Hungarian composer Béla Bartók, who lived from 1881 to 1945. Bartók is the largest crater of the Kuiperian system on Mercury, at 118 km diameter. It is followed by Amaral crater. Within the central peak complex of Bartók is a ''dark spot'' of low reflectance material (LRM).Zhiyong Xiao, Robert G. Strom, David T. Blewett, Paul K. Byrne, Sean C. Solomon, Scott L.

Raphael (crater)
Raphael is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 1976, and is named for the Italian painter Raphael (Raffaello Sanzio da Urbino). Unlike other Mercurian craters of similar size, Raphael is not multi-ringed. The crater Flaiano lies just south of the center of Raphael. There is also a high- albedo area east of Flaiano, that is associated with irregular depressions. The depressions are similar to those within Navoi Navoiy (), also spelled Navoi, is a city and the capital of Navoiy Region in the southwestern part of Uzbekistan. Administratively, it is a district-level city, that includes the urban-type settlement Tinchlik. It is located at latitude 40° 5' 4 ..., Lermontov, Scarlatti, and Praxiteles. The depressions resemble those associated with volcanic explosions. References Impact craters on Mercury Raphael {{crater-stub ...
