Stiborius (crater)
Stiborius is a lunar impact crater that lies to the south-southwest of the crater Piccolomini, in the southeastern quadrant of the Moon's near side. To the south-southwest of Stiborius is the smaller Wöhler. Stiborius is 44 kilometers in diameter and 3.7 kilometers deep.''Autostar Suite Astronomer Edition''. CD-ROM. Meade, April 2006. The rim of this crater is well-defined with little appearance of erosion. It is roughly circular in form, but has a prominent outward bulge to the northeast where the side has slumped into the interior. There is a terrace-like shelf along the southeastern and northern inner walls. The interior floor is somewhat irregular, and there is a low central peak at the midpoint that is connected to the northeastern wall by a low ridge. It is from the Upper Imbrian period, 3.8 to 3.2 billion years ago. It is named after Andreas Stöberl Andreas Stöberl (c. 1464 Grössing, Helmuth: "Stiborius, Andreas", pp.261f. in Henschel, Christine; Jahn, Bruno (eds.): ...

Lunar Orbiter 4
Lunar Orbiter 4 was a robotic U.S. spacecraft, part of the Lunar Orbiter Program, designed to orbit the Moon, after the three previous orbiters had completed the required needs for 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 cislunar trajectory and injected into an elliptical near polar high lunar orbit In celestial mechanics, an orbit is the curved trajectory of an object such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or ...

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 ori ... [...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 ...

Piccolomini (crater)
Piccolomini is a prominent lunar impact crater located in the southeastern sector of the Moon. The crater is named after 16th century Italian Archbishop and astronomer Alessandro Piccolomini.''Autostar Suite Astronomer Edition''. CD-ROM. Meade, April 2006. The crater Rothmann lies to the west-southwest, and to the south is Stiborius. The lengthy Rupes Altai begins at the western rim of Piccolomini, curving to the northwest. It is 88 kilometers in diameter and 4,500 meters deep. It is from the Upper Imbrian The Imbrian is a lunar geologic period divided into two epochs, the Early and Late.

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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wöhler (crater)
Wöhler is a small lunar impact crater that lies to the south of the crater Stiborius, in the rugged southeastern highlands of the Moon. It was named after German chemist Friedrich Wöhler Friedrich Wöhler () FRS(For) HonFRSE (31 July 180023 September 1882) was a German chemist known for his work in inorganic chemistry, being the first to isolate the chemical elements beryllium and yttrium in pure metallic form. He was the first .... To the west-northwest is the battered remnant of Riccius. This is a generally circular crater formation with a slightly eroded outer rim. There is a small crater attached to the western rim. The inner walls slope down to a featureless inner floor. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Wöhler.

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' ...

Upper Imbrian
The Imbrian is a lunar geologic period divided into two epochs, the Early and Late. Early Imbrian In the lunar geologic timescale, the Early Imbrian epoch occurred from 3,850 million years ago to about 3,800 million years ago. It overlaps the end of the Late Heavy Bombardment of the Inner Solar System. The impact that created the huge Mare Imbrium basin occurred at the start of the epoch. The other large basins that dominate the lunar near side (such as Mare Crisium, Mare Tranquillitatis, Mare Serenitatis, and Mare Fecunditatis) were also formed in this period. These basins filled with basalt mostly during the subsequent Late Imbrian epoch. The Early Imbrian was preceded by the Nectarian. Late Imbrian In the Lunar geologic timescale, the Late Imbrian epoch occurred between 3800 million years ago to about 3200 million years ago. It was the epoch during which the mantle below the lunar basins partially melted and filled them with basalt. The melting is thought to have oc ...
