Munkácsy (crater)
Munkácsy, named after Mihály Munkácsy, is a crater on Mercury. Munkácsy originally had a double-ring basin structure, but most of the inner ring was buried when the basin was flooded with volcanic lava. Only a few remnants of the ring poke up through the lava, although low ridges in the lava seem to trace out much of the rest of the ring's circumference. Munkácsy is one of 110 peak ring basins on Mercury. The name of the crater was adopted by the International Astronomical Union in 2009. Munkácsy is named for the Hungarian painter Mihály Munkácsy. The crater Fonteyn Fonteyn is a Dutch surname. Notable people with the surname include: * Carel Fonteyn (fl. 1655–1665), Flemish painter * Margot Fonteyn (1919–1991), English ballerina * Mathieu Fonteyn (born 1985), Belgian swimmer * Sam Fonteyn (1925–1991), En ... is to the northwest of Munkácsy, and the crater Raditladi is to the northeast.

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] |
Raditladi Quadrangle
The Raditladi quadrangle (H-4) is one of fifteen quadrangles on Mercury. It runs from 270 to 180° longitude and 20 to 70° latitude. Named after the Raditladi Basin, it was mapped in detail for the first time after ''MESSENGER'' entered orbit around Mercury in 2011. It had not been mapped prior to that point because it was one of the six quadrangles that was not illuminated (with the exception of a thin strip of its territory along the eastern border with Shakespeare quadrangle) when ''Mariner 10'' made its flybys in 1974 and 1975. These six quadrangles continued to be known by their albedo feature names, with this one known as the Liguria quadrangle. The Caloris basin is centered in Raditladi quadrangle, though it overlaps significantly with the Tolstoj and Shakespeare quadrangles. The Borealis quadrangle is north of Raditladi quadrangle. To the west is Hokusai quadrangle, and to the east is Shakespeare quadrangle. To the southwest is Eminescu quadrangle, and to the so ...

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] |
Mihály Munkácsy
Mihály Munkácsy (20 February 1844 – 1 May 1900) was a Hungarians, Hungarian Painting, painter. He earned international reputation with his Genre works, genre pictures and large-scale Christian art, biblical paintings. Early years Munkácsy was born as ''Mihály Leó Lieb'' ( hu, Lieb Mihály Leó) to Mihály Lieb, an bureaucrat of Bavarian origin, and Cecília Reök, in Munkács, Kingdom of Hungary (1526–1867), Hungary, Austrian Empire, the town from which he later adopted his pseudonym. After being apprenticed to itinerant painter Elek Szamossy, Munkácsy went to Pest (city), Pest, the largest city in Hungary (now part of Budapest), where he sought the patronage of established artists. With the help of the landscape artist Antal Ligeti, he received a state grant to study abroad. In 1865, he studied at the Academy of Vienna under Karl Rahl. In 1866, he studied at the Munich Academy, and in 1868 he moved to the Kunstakademie Düsseldorf to study with the popular Genre ...

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-co ... [...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.

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.

Raditladi (crater)
Raditladi is a large impact crater on Mercury with a diameter of 263 km. Inside its peak ring there is a system of concentric extensional troughs (graben), which are rare surface features on Mercury. The floor of Raditladi is partially covered by relatively light smooth plains, which are thought to be a product of the effusive volcanism. The troughs may also have resulted from volcanic processes under the floor of Raditladi. The basin is relatively young, probably younger than one billion years, with only a few small impact craters on its floor and with well-preserved basin walls and peak-ring structure. It 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. G., 2018.
