Firdousi (crater)
Firdousi is a crater on Mercury. It has a diameter of 98 kilometers. Its name was adopted by the International Astronomical Union (IAU) in 2010. Firdousi is named for the Persian poet Ferdowsi Abu'l-Qâsem Ferdowsi Tusi (also Firdawsi, ; 940 – 1019/1025) was a Persians, Persian poet and the author of ''Shahnameh'' ("Book of Kings"), which is one of the world's longest epic poetry, epic poems created by a single poet, and the gre ..., who lived from 940 to 1020.

Derain Quadrangle
The Derain quadrangle (H-10) is one of fifteen quadrangles on Mercury. It runs from 288° to 360° west longitude and from 22° S to 22° N latitude. Named after the Derain crater, 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 when ''Mariner 10'' made its flybys in 1974 and 1975. These six quadrangles continued to be known by their albedo feature In planetary geology, an albedo feature is a large area on the surface of a planet (or other Solar System body) which shows a contrast in brightness or darkness (albedo) with adjacent areas. Historically, albedo features were the first (and usu ... names, with this one known as the Pieria quadrangle. The hypothetical Skinakas Basin was thought to exist on the west side of the quadrangle, but MESSENGER images did not confirm its existence. The large Lennon-Picasso ...

Mercury (planet)
Mercury is the first planet from the Sun. It is a rocky planet with a trace atmosphere. While it is the List of Solar System objects by size, smallest and least massive planet of the Solar System, its surface gravity is slightly higher than that of Mars. The surface of Mercury is similar to Earth's Moon, heavily Impact crater, cratered, with expansive rupes system, generated from thrust faults, and bright ray systems, formed by ejecta. Its largest crater, Caloris Planitia, has a diameter of , which is about one-third the diameter of the planet (). Being the most inferior planet, inferior orbiting planet it appears in Earth's sky, always close to the Sun, either as a "morning star" or an "evening star". It stays most of the time the closest to all other planets and is the planet with the highest delta-v needed to travel to from all other planets of the Solar System. Mercury's sidereal year (88.0 Earth days) and sidereal day (58.65 Earth days) are in a 3:2 ratio. This relation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferdowsi
Abu'l-Qâsem Ferdowsi Tusi (also Firdawsi, ; 940 – 1019/1025) was a Persians, Persian poet and the author of ''Shahnameh'' ("Book of Kings"), which is one of the world's longest epic poetry, epic poems created by a single poet, and the greatest epic of Persian-speaking people, Persian-speaking countries. Ferdowsi is celebrated as one of the most influential figures of Persian literature and one of the greatest in the history of literature. Name Except for his ''kunya (Arabic), kunya'' ( – , meaning 'father of Qasem') and his Takhallus, pen name ( – ''Ferdowsī'', meaning 'Paradise, paradisic'), nothing is known with any certainty about his full name. According to Djalal Khaleghi-Motlagh, the information given by the 13th-century author Bundari about Ferdowsi's name should be taken as the most reliable. Bundari calls the poet al-Amir al-Hakim Abu'l-Qasem Mansur ibn al-Hasan al-Ferdowsi al-Tusi. From an early period on, he has been referred to by different additional na ...

International Astronomical Union
The International Astronomical Union (IAU; , UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded on 28 July 1919 in Brussels, Belgium 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. the Union had 85 national members and 12,734 individual members, spanning 90 countries and territories. 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 ...

Persian Literature
Persian literature comprises oral compositions and written texts in the Persian language and is one of the world's oldest literatures. It spans over two-and-a-half millennia. Its sources have been within Greater Iran including present-day Iran, Iraq, Afghanistan, Pakistan, the Caucasus, and Turkey, regions of Central Asia (such as Tajikistan), South Asia and the Balkans where the Persian language has historically been either the native or official language. For example, Rumi, one of the best-loved Persian poets, born in Balkh (in modern-day Afghanistan) or Wakhsh (in modern-day Tajikistan), wrote in Persian and lived in Konya (in modern-day Turkey), at that time the capital of the Seljuks in Anatolia. The Ghaznavids conquered large territories in Central and South Asia and adopted Persian as their court language. There is thus Persian literature from Iran, Mesopotamia, Azerbaijan, the wider Caucasus, Turkey, Pakistan, Bangladesh, India, Tajikistan and other parts of Cent ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agencies of the United States government, independent agency of the federal government of the United States, US federal government responsible for the United States's civil list of government space agencies, space program, aeronautics research and outer space, space research. National Aeronautics and Space Act, Established in 1958, it succeeded the National Advisory Committee for Aeronautics (NACA) to give the American space development effort a distinct civilian orientation, emphasizing peaceful applications in space science. It has since led most of America's space exploration programs, including Project Mercury, Project Gemini, the 1968–1972 Apollo program missions, the Skylab space station, and the Space Shuttle. Currently, NASA supports the International Space Station (ISS) along with the Commercial Crew Program and oversees the development of the Orion (spacecraft), Orion spacecraft and the Sp ...

Hollows (Mercury)
Hollows are a landform on the planet Mercury, discovered during the ''MESSENGER'' mission that orbited the planet from 2011 to 2015. Hollows are typically clusters of rimless depressions with flat floors and haloes of bright (high albedo) material surrounding them. Hollows are thought to form by loss of volatiles from the surface by sublimation, caused by the intense solar radiation on the airless planet. They are some of the youngest features on Mercury. Hollows were first observed as bright areas within craters imaged by the Mariner 10 spacecraft in 1974, but the images were not of sufficient resolution to discern any detail. These craters include Balzac, Tyagaraja, Theophanes, Zeami, and Hopper.Dzurisin, D., 1977. Mercurian bright patches: Evidence for physio-chemical alteration of surface material?
