Licetus (crater)
Licetus is a lunar impact crater on the near side of the Moon, in the rugged southern highland region. It lies to the south of the walled plain Stöfler, and is attached to the northern rim of the sub-divided crater Heraclitus. Just to the southeast is Cuvier Jean Léopold Nicolas Frédéric, Baron Cuvier (; 23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French naturalist and zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in nat .... Licetus is 75 kilometers in diameter and 3.8 kilometers deep. It is from the Pre-Nectarian period, 4.55 to 3.92 billion years ago.''Autostar Suite Astronomer Edition''. CD-ROM. Meade, April 2006. It is a worn crater formation with several craterlets across its rim and along its inner wall. The most notable of these is a small crater across the inner southeast rim, with another across the northwest rim. The rim is also especially worn along the northern end, with a cluster ...

Lunar Orbiter 4
Lunar Orbiter 4 was a robotic U.S. spacecraft, part of the Lunar Orbiter program, Lunar Orbiter Program, designed to orbit the Moon, after the three previous orbiters had completed the required needs for Project Apollo, Apollo mapping and site selection. It was given a more general objective, to "perform a broad systematic photographic survey of lunar surface features in order to increase the scientific knowledge of their nature, origin, and processes, and to serve as a basis for selecting sites for more detailed scientific study by subsequent orbital and landing missions". It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data. Mission Summary The spacecraft was placed in a Free-return trajectory, cislunar trajectory and injected into an elliptical near polar high lunar orbit for data acquisition. The orbit was with an inclination of 85.5 degrees and a period of 12 hours. After initial photography on May 11, 1967 problems started occu ...

Fortunio Liceti
Fortunio Liceti (Latin: ''Fortunius Licetus''; October 3, 1577 – May 17, 1657), was an Italian physician and philosopher. Life and career He was born prematurely at Rapallo, near Genoa to Giuseppe Liceti and Maria Fini, while the family was moving from Recco. His father was a doctor and created a makeshift incubator, thereby saving Fortunio. Fortunio studied with his father from 1595 until 1599, when he moved on to the University of Bologna, where he studied philosophy and medicine. There his teachers included Giovanni Costeo and Federico Pendasio, two men whom Liceti respected so much he later named his first son in their honor (Giovanni Federico Liceti). In October 1599, Giuseppe Liceti fell fatally ill and Fortunio returned to Genoa, where Giuseppe was now practicing medicine. On March 23, 1600, Liceti received his doctorate in philosophy and medicine. On November 5 of that year, Liceti took a position as lecturer of logic at the University of Pisa and in 1605, he was awar ...

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 word for "vessel" (, a Greek vessel used to mix wine and water). Galileo built his 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. Scientific opinion as to the origin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity 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. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, 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, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stöfler (crater)
Stöfler is a large lunar impact crater located in the crater-dotted southern highlands. It was named after 15th-16th century German astronomer and mathematician Johannes Stöffler. It sits to the west of the crater Maurolycus. The distorted crater Fernelius is attached to the northern rim, and Miller and Nasireddin lie to the west. Faraday has overlain and damaged the western rim, and this crater in turn has been overlain by several smaller craters. The rim of Stöfler is worn and eroded, but the outline remains relatively intact except where overlain by Faraday. The smaller Stöfler K intrudes into the northwestern rim, and Stöfler F forms an indentation into the base of the southwestern interior wall. The crater floor has been filled in with deposits, either from lava flows or ejecta from basin impacts, and is relatively flat and featureless in the northwest half. If there was a central peak, it has now become buried. The floor has a low albedo Albedo (; ) is the measu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heraclitus (crater)
Heraclitus is a complex lunar impact crater that lies in the rugged southern highlands of the Moon. The crater Licetus forms the northern end of the formation. Just to the east is Cuvier, and due south is Lilius. Just to the west of Heraclitus is the small satellite crater Heraclitus K, to the south of which is a pair of larger overlapping craters, Lilius E and Lilius D.''Autostar Suite Astronomer Edition''. CD-ROM. Meade, April 2006. The entire formation is heavily worn, with features smoothed down by a long history of impacts. Heraclitus is a complex formation composed of three sections divided by a triple-armed interior ridge. Of the three sections, the most eroded and irregular is at the eastern end where the outer rim forms a low ridge that joins to Cuvier. The circular southwest end is the most intact section, forming the circular satellite crater Heraclitus D, which is attached to the other two sections along the northeast rim. There are a pair of ghost-crater rims on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuvier (crater)
Cuvier is a Lunar craters, lunar impact crater on the southern part of the Moon's near side. It is attached to the east-southeast rim of the unusually shaped formation Heraclitus (crater), Heraclitus. To the northeast is the crater Clairaut (crater), Clairaut. The rim of this crater has been worn and eroded by subsequent impacts, leaving an outer wall that has been rounded and diminished in prominence. There is a small but notable crater pair lying across the northern rim, and two other smaller craters lie along the east and south rims. There are also several small craterlets lying across the rim to the north-northwest. Where the rim is shared with Heraclitus, there is a slight inward bulge to the wall, producing a short section where the rim appears slightly flatter. The interior floor is level and nearly featureless, and much of the floor appears to have been resurfaced. This surface does not possess the low albedo characteristic of the lunar mare, and it matches the hue of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pre-Nectarian
The pre-Nectarian period of the lunar geologic timescale runs from 4.533 billion years ago (the time of the initial formation of the Moon) to 3.920 billion years ago, when the Nectaris Basin was formed by a large impact. It is followed by the Nectarian period. Description Pre-Nectarian rocks are rare in the lunar sample suite; they are mostly composed of lunar highlands material which have been heavily churned, brecciated, and thermally affected by subsequent impacts, particularly during the Heavy Bombardment Eon (HBE; a period of 0.6-1 Gy from the formation of the Moon until at least the formation of the Imbrium Basin ~3.9 Ga, or even later with the formation of Orientalis Basin) that marks the approximate beginning of the Nectarian period. The primary pre-Nectarian lunar highland material is dominated by the rock type anorthosite, which suggests that the early stage of lunar crustal formation occurred via mineral crystallization of a global magma ocean. This geologic period has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalmbach Books
Kalmbach Media (formerly Kalmbach Publishing Co.) is an American publisher of books and magazines, many of them railroad-related, located in Waukesha, Wisconsin. History The company's first publication was ''The Model Railroader'', which began publication in the summer of 1933 with a cover date of January 1934. A press release announcing the magazine appeared in August 1933, but did not receive much interest. In 1940, business was good enough for Kalmbach to launch another magazine about railroads in general with the simple title of ''Trains Magazine''. From its first issue dated November 1940, it grew quickly from an initial circulation of just over 5,000. Kalmbach became exclusively a publisher when it discontinued its printing operations in 1973, opting to contract production from other printers. In 1985, Kalmbach purchased AstroMedia Corporation, adding its four magazines: ''Astronomy'', ''Deep Sky'', the children's science magazine ''Odyssey'' and ''Telescope Making'' ...
