Capella (crater)
Capella is a Lunar craters, lunar impact crater in diameter that lies to the north of the Mare Nectaris, in a rugged region with many small impact craters. It was named after Roman astronomer Martianus Capella. It intrudes slightly into the eastern rim of the crater Isidorus (crater), Isidorus, a feature only slightly smaller in diameter. The wall of Capella is low but relatively thick and irregular, with a large promontory intruding on the south-eastern side. The crater is crossed by a deep rift, the Vallis Capella, which passes directly through Capella from the north rim through the southeast side of the wall, and extends out both sides for a combined distance of 110 kilometers. This feature was formed by a chain of craters. In the middle of the crater is a wide, round peak with a craterlet at the top. The western side of the crater is dotted with impact debris, forming clusters of small hills. Satellite craters By convention these features are identified on lunar maps by pla ...

Apollo 16
Apollo 16 (April 1627, 1972) was the tenth human spaceflight, crewed mission in the United States Apollo program, Apollo space program, administered by NASA, and the fifth and penultimate to Moon landing, land on the Moon. It was the second of Apollo's "List of Apollo missions#Alphabetical mission types, J missions", with an extended stay on the Geology of the Moon#Lunar landscape, lunar surface, a focus on science, and the use of the Lunar Roving Vehicle (LRV). The landing and Exploration of the Moon, exploration were in the Descartes Highlands, a site chosen because some scientists expected it to be an area formed by volcanic action, though this proved not to be the case. The mission was crewed by Astronaut ranks and positions, Commander John Young (astronaut), John Young, Lunar Module Pilot Charles Duke and Command Module Pilot Ken Mattingly. Launched from the Kennedy Space Center in Florida on April 16, 1972, Apollo 16 experienced a number of minor glitches en route to the ...

Martianus Capella
Martianus Minneus Felix Capella () was a jurist, polymath and Latin literature, Latin prose writer of late antiquity, one of the earliest developers of the system of the seven liberal arts that structured early medieval education. He was a native of M'Daourouch, Madaura. His single encyclopedic work, ''De nuptiis Philologiae et Mercurii'' ("On the Marriage of Philology and Mercury"), also called ''De septem disciplinis'' ("On the seven disciplines"), is an elaborate didactic allegory written in a mixture of prose and elaborately allusion, allusive verse. Martianus often presents philosophical views based on Neoplatonism, the Platonism, Platonic school of philosophy pioneered by Plotinus and his followers. Like his near-contemporary Macrobius, who also produced a major work on Religion in ancient Rome, classical Roman religion, Martianus never directly identifies his own religious affiliation. Much of his work occurs in the form of dialogue, and the views of the interlocutors ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isidorus Crater Capella Crater AS11-42-6232
Isidore ( ; also spelled Isador, Isadore and Isidor) is a masculine given name. The name is derived from the Greek name ''Isídōros'' (Ἰσίδωρος, latinized ''Isidorus'') and can literally be translated to 'gift of Isis'. The name has survived in various forms throughout the centuries. Although it has never been a common name, it has historically been popular due to its association with Catholic figures and among the Jewish diaspora. Isidora is the feminine form of the name.

Lunar Craters
Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, all of which were formed by impacts. The International Astronomical Union currently recognizes 9,137 craters, of which 1,675 have been dated. History The word ''crater'' was adopted from the Greek language, Greek word for "vessel" (, a Greek vessel used to mix wine and water). Galileo built his refracting telescope, first telescope in late 1609, and turned it to the Moon for the first time on November 30, 1609. He discovered that, contrary to general opinion at that time, the Moon was not a perfect sphere, but had both mountains and cup-like depressions. These were named craters by Johann Hieronymus Schröter (1791), extending its previous use with volcanoes. Robert Hooke in ''Micrographia'' (1665) proposed two hypotheses for lunar crater formation: one, that the craters were caused by projectile bombardment from space, the other, that they were the products of subterranean lunar volcanism. ...

Impact Crater
An impact crater is a depression (geology), depression in the surface of a solid astronomical body formed by the hypervelocity impact event, impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Impact craters are typically circular, though they can be elliptical in shape or even irregular due to events such as landslides. Impact craters range in size from microscopic craters seen on lunar rocks returned by the Apollo Program to simple bowl-shaped depressions and vast, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury (planet), Mercury, Callisto (moon), Callisto, Ganymede (moon), Ganymede, and most small moons and asteroids. On other planet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mare Nectaris
Mare Nectaris (Latin ''nectaris'', the "Sea of Nectar") is a small lunar mare or sea (a volcanic lava plain noticeably darker than the rest of the Moon's surface) located south of Mare Tranquillitatis southwest of Mare Fecunditatis, on the near side of the Moon. Montes Pyrenaeus borders the mare to the east and Sinus Asperitatis fuses to its northwestern edge. It is 84,000 square kilometers in size. Several large craters are situated at the borders of Mare Nectaris. The biggest one is lava-filled Fracastorius (124 km), which fuses with the southern coast of the Sea. A prominent trio of 100-km craters Theophilus, Cyrillus and Catharina is located near northwestern coast. Other notable feature is a " ghost crater" Daguerre, almost entirely covered with lava, in the northern part of Mare Nectaris. Mare Nectaris is located in the central part of 860-km-diameter impact basin, which was formed 3.8–3.9 billion years ago. This event marks the beginning of Nectarian period ...

Isidorus (crater)
Isidorus is a lunar impact crater that is located to the north of the Mare Nectaris, on the eastern half of the Moon's near side. It was named after Spanish astronomer Saint Isidore of Seville. It forms a pair with the slightly larger Capella, which is attached to the east-northeastern rim. To the west-southwest across the lunar mare are Mädler and the prominent Theophilus. The rim of Isidorus is circular and somewhat eroded, with several tiny craterlets lying across the northern rim. The interior floor has been resurfaced by lava Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a Natural satellite, moon onto its surface. Lava may be erupted at a volcano or through a Fissure vent, fractu ... and is generally level, although it is marked by the small, bowl-shaped crater Isidorus A along the western rim. There is a tiny remnant of a craterlet attached to the northern rim of the latter format ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Promontory
A promontory is a raised mass of land that projects into a lowland or a body of water (in which case it is a peninsula). Most promontories either are formed from a hard ridge of rock that has resisted the erosive forces that have removed the softer rock to the sides of it, or are the high ground that remains between two river valleys where they form a confluence. One type of promontory is a headland, or head. Promontories in history Located at the edge of a landmass, promontories offer a natural defense against enemies, as they are often surrounded by water and difficult to access. Many ancient and modern forts and castles have been built on promontories for this reason. One of the most famous examples of promontory forts is the Citadel of Namur in Belgium. Located at the confluence of the Meuse and Sambre rivers, the citadel has been a prime fortified location since the 10th century. The surrounding rivers act as a natural moat, making it difficult for enemies to access ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
