Nabokov (crater)
Nabokov is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) on April 24, 2012. Nabokov is named for the Russian and American author Vladimir Nabokov. Nabokov 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.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vladimir Nabokov
Vladimir Vladimirovich Nabokov (russian: link=no, Владимир Владимирович Набоков ; 2 July 1977), also known by the pen name Vladimir Sirin (), was a Russian-American novelist, poet, translator, and entomologist. Born in Imperial Russia in 1899, Nabokov wrote his first nine novels in Russian (1926–1938) while living in Berlin, where he met his wife. He achieved international acclaim and prominence after moving to the United States, where he began writing in English. Nabokov became an American citizen in 1945 and lived mostly on the East Coast before returning to Europe in 1961, where he settled in Montreux, Switzerland. From 1948 to 1959, Nabokov was a professor of Russian literature at Cornell University. Nabokov's 1955 novel '' Lolita'' ranked fourth on Modern Library's list of the 100 best 20th-century novels in 2007 and is considered one of the greatest 20th-century works of literature. Nabokov's ''Pale Fire'', published in 1962, was ranked ... [...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 most ... [...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 management f ...

Peak Ring
A peak ring crater is a type of complex crater, which is different from a multi-ringed basin or central-peak crater. A central peak is not seen; instead, a roughly circular ring or plateau, possibly discontinuous, surrounds the crater's center, with the crater rim still farther out from the center. Formation The rings form by different processes, and inner rings may not be formed by the same processes as outer rings.Geology Pagewww.geologypage.com/2016/10/research-helps-explain-formation-ringed-crater-moon.html accessdate: February 5, 2017 It has long been the view that peak rings are formed in the stage subsequent to central peak formation in craters. The central peaks of craters are believed to originate from hydrodynamic flow of material lifted by inward-collapsing crater walls, while impact-shattered rock debris is briefly turned to fluid by strong vibrations that develop during crater formation. The peak-ring structure of Chicxulub crater was probably formed as inward-coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lennon-Picasso Basin
The Lennon-Picasso Basin is an ancient (Pre- Tolstojan) impact basin on Mercury, discovered from topographic mapping of the surface by the MESSENGER spacecraft. It is approximately 1450 km in diameter and spans the region between Picasso crater on the north rim to Lennon crater on the south rim, and the crater Holst is near the center. The basin is heavily eroded by subsequent impacts and is not obvious on the surface. A topographic low is present near the center, and scarps representing a remnant of the eastern basin rim are intact. The scarps include the highest point on the planet.Denevi, B. W., Ernst, C.
