Saussure (crater)
Saussure is a Lunar craters, lunar impact crater. It is located in the crater-riddled terrain in the southern hemisphere of the Moon's near side. Just to the north and nearly attached to the rim is the larger crater Orontius (crater), Orontius. About a half crater diameter due west is the slightly larger crater Pictet (crater), Pictet. Just to the east is a curving ridge in the surface, possibly the remains of a crater that has been almost completely overlaid by Saussure. The outer rim of Saussure is worn but relatively intact, with only the southern edge being somewhat disrupted. A small impact lies across the northeastern rim and a pair of craterlets along the western edge. The inner walls are relatively featureless, and slope down to the generally level interior floor. This bottom surface is marked only by a few tiny craters. It was named after 18th century Republic of Geneva, Genevan geologist Horace Bénédict de Saussure. He was the professor, and later colleague and friend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Horace Bénédict De Saussure
Horace Bénédict de Saussure (; 17 February 1740 – 22 January 1799) was a Genevan geologist, meteorologist, physicist, mountaineer and Alpine explorer, often called the founder of alpinism and modern meteorology, and considered to be the first person to build a successful solar oven. Early life and education Horace Bénédict de Saussure was born 17 February 1740, in Conches, near Geneva (''today in Switzerland but then an independent republic''). Saussure's family were Genevan patricians. His father, Nicolas de Saussure, was an agriculturist, agronomist and author. Because his mother was "sickly", Saussure was brought up by his mother's sister and her husband the Genevan naturalist Charles Bonnet, who sparked Horace-Bénédict's early interest in botany. After attending the "Collège" of his hometown, he completed his studies at the Geneva Academy in 1759 with a dissertation on heat (''Dissertatio physica de igne''). Career In 1760, Saussure made the first of nume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Moon
The Moon is Earth's only natural satellite. It Orbit of the Moon, orbits around Earth at Lunar distance, an average distance of (; about 30 times Earth diameter, Earth's diameter). The Moon rotation, rotates, with a rotation period (lunar day) that is synchronized to its orbital period (Lunar month#Synodic month, lunar month) of 29.5 Earth days. This is the product of Earth's gravitation having tidal forces, tidally pulled on the Moon until one part of it stopped rotating away from the near side of the Moon, near side, making always the same lunar surface face Earth. Conversley, the gravitational pull of the Moon, on Earth, is the main driver of Earth's tides. In geophysical definition of planet, geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.2% that of the Earth, and its diameter is , roughly one-quarter of Earth's (about as wide as the contiguous United States). Within the Solar System, it is the List of Solar System objects by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orontius (crater)
Orontius is a lunar impact crater that lies in the heavily cratered southern highlands of the Moon's near side. It was named after 16th century French mathematician Oronce Fine. It is located to the northwest of the prominent ray crater Tycho Tycho is a masculine given name, a latinization of Greek Τύχων, from the name of Tyche (), the Greek goddess of fortune or luck. The Russian form of the name is '' Tikhon'' (Тихон). People Given name * Tycho Brahe (1546–1601), Dan ..., and south and east of the large walled plain Deslandres. The eastern part of the crater is overlain by the smaller crater Huggins, which is overlain in turn on its eastern rim by the still smaller Nasireddin, the trio forming a crater chain of diminishing dimensions. Joined to the southern rim is the crater Saussure. To the southwest, just east of Tycho, is Pictet. The rim of Orontius is battered, worn, and overlain by a number of different craters. A pair of craters to the west have in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pictet (crater)
Pictet is a lunar impact crater located just to the east of the larger and more prominent impact crater Tycho. The high-albedo Albedo ( ; ) is the fraction of sunlight that is Diffuse reflection, diffusely reflected by a body. It is measured on a scale from 0 (corresponding to a black body that absorbs all incident radiation) to 1 (corresponding to a body that reflects ... rays and ejecta from Tycho lie across Pictet and spread far to the east and in other directions. Pictet is older than Tycho and is somewhat worn by past impacts. The slightly smaller crater Pictet A intrudes slightly into the southwest rim. The larger crater Pictet E is nearly joined to the north rim. To the east is Saussure, and to the northeast is the larger, worn formation Orontius. Swiss physicist Marc-Auguste Pictet (eponym of Pictet crater) was the student and later colleague and friend of Horace-Bénédict de Saussure (eponym of nearby Saussure crater).

Republic Of Geneva
The Canton of Geneva, officially the Republic and Canton of Geneva, is one of the Cantons of Switzerland, 26 cantons of the Switzerland, Swiss Confederation. It is composed of forty-five Municipality, municipalities, and the seat of the government and parliament is in the Geneva, city of Geneva. Geneva is the French-speaking westernmost canton of Switzerland. It lies at the western end of Lake Geneva and on both sides of the Rhone, its main river. Within the country, the canton borders Vaud to the east, the only adjacent canton. However, most of Geneva's border is with France, specifically the region of Auvergne-Rhône-Alpes. As is the case in several other Swiss cantons (Ticino, canton of Neuchâtel, Neuchâtel, and canton of Jura, Jura), Geneva is referred to as a republic within the Swiss Confederation. One of the most populated cantons, Geneva is considered one of the most cosmopolitan regions of the country. As a center of the Calvinism, Calvinist Protestant Reformation, Re ...

Marc-Auguste Pictet
Marc-Auguste Pictet (; 23 July 1752 – 19 April 1825) was a Genevan scientific journalist and experimental natural philosopher. Pictet's main contribution to learning was his editing of the scientific section of the '' Bibliothèque Britannique'' (1796–1815), a publication devoted to the diffusion on the Continent of knowledge and arts produced in Great Britain. His own scientific research focused on the fields of physical science, especially calorimetry, but also astronomy, geology, meteorology and technology, especially chronometry and the manufacture of fine earthenware. Life He was born in Geneva, Republic of Geneva on 23 July 1752, the son of Charles Pictet, a military officer serving in the mercenary troops of the Netherlands, and his wife, Marie Dunant. Marc-Auguste studied natural philosophy and law at the Academy of Geneva and qualified as a lawyer in 1774.
