Bouguer (lunar Crater)
Bouguer is a lunar impact crater that lies along the southern edge of the Mare Frigoris, to the north of the crater Bianchini. To the west-southwest of Bouguer, along the same shore of the mare, is the crater Foucault. Nearly due west is the more prominent Harpalus, and to the west is La Condamine La Condamine ( lij, A Cundamina ) is the central ward in the Principality of Monaco. Its landmarks include Port Hercules, the Rainier III Nautical Stadium, and the Princess Antoinette Park. Its farmer's market at the ''Place d'Armes'' dates fro .... This is a relatively young crater with well-defined edge. The formation is relatively circular, but there are slight outward bulges to the east, north-northwest, and southwest. There is some evidence of slumping in the eastern bulge. The interior floor occupies about half the crater diameter, and is relatively level and featureless.

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 ...

Pierre Bouguer
Pierre Bouguer () (16 February 1698, Croisic – 15 August 1758, Paris) was a French mathematician, geophysicist, geodesist, and astronomer. He is also known as "the father of naval architecture". Career Bouguer's father, Jean Bouguer, one of the best hydrographers of his time, was Regius Professor of hydrography at Le Croisic in lower Brittany, and author of a treatise on navigation. He taught his sons Pierre and Jan at their home, where he also taught private students. In 1714, at the age of 16, Pierre was appointed to succeed his deceased father as professor of hydrography. In 1727 he gained the prize given by the French Academy of Sciences for his paper ''On the masting of ships'', beating Leonhard Euler; and two other prizes, one for his dissertation ''On the best method of observing the altitude of stars at sea'', the other for his paper ''On the best method of observing the variation of the compass at sea''. These were published in the Prix de l'Académie des Science ... [...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 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 ...

Mare Frigoris
Mare Frigoris (Latin ''frīgōris'', the "Sea of Cold") is a lunar mare in the far north of the Moon. It is located in the outer rings of the Procellarum basin, just north of Mare Imbrium, and stretches east to north of Mare Serenitatis. It is just north of the dark crater Plato (crater), Plato. The basin material surrounding the mare is of the Lower Imbrian epoch (geology), epoch, while the eastern mare material is of the Upper Imbrian epoch, and the western mare material is of the Eratosthenian epoch. Like most of the other maria on the Moon, Mare Frigoris was named by Giovanni Riccioli, whose 1651 nomenclature system has become standardized. Previously, William Gilbert (astronomer), William Gilbert had included it among the Insula Borealis ("Northern Island") in his map of ''c''.1600, and Michael Van Langren had labelled it the Mare Astronomicum ("Sea of Astronomy") in his 1645 map. Pierre Gassendi called it the Boreum Mare ('Northern Sea').Ewen A. Whitaker, ''Mapping and Nami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bianchini (lunar Crater)
Bianchini is a lunar impact crater that lies along the northern Jura Mountains that ring the Sinus Iridum, in the northwestern part of the near side of the Moon. It was named after Italian astronomer Francesco Bianchini Francesco Bianchini (13 December 16622 March 1729) was an Italian philosopher and scientist. He worked for the curia of three popes, including being ''camiere d'honore'' of Clement XI, and secretary of the commission for the reform of the cal .... The impact of this crater near the edge of the Jura Mountains deposited some material into the Sinus Iridum floor. The rim of this crater is not significantly worn, although there is a small crater along the inner side of the eastern rim. Within the inner wall is a somewhat irregular floor and a small cluster of ridges at the midpoint. Portions of the inner wall have slumped toward the floor along the northern edges. Satellite craters By convention these features are identified on lunar maps by placing the letter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foucault (crater)
Foucault is a small lunar impact crater that lies along the southern edge of Mare Frigoris, to the southeast of the crater Harpalus. In the rugged terrain to the south of Foucault is Sharp. The outer perimeter of Foucault forms a somewhat irregular circle, with slight outward bulges to the south and northeast. The inner wall of the rim is not notably terraced, and slopes down directly to the uneven floor. It is named after physicist Léon Foucault, most famous for the Foucault pendulum The Foucault pendulum or Foucault's pendulum is a simple device named after French physicist Léon Foucault, conceived as an experiment to demonstrate the Earth's rotation.

Harpalus (crater)
Harpalus is a young lunar impact crater that lies on the Mare Frigoris, at the eastern edge of the Sinus Roris. To the southeast at the edge of the mare is the small crater Foucault, and to the northwest on the opposite edge is the walled plain named South. The rim of Harpalus is sharp-edged with little sign of wear or erosion. The wall is not perfectly circular, and has a few outward notches and protrusions, especially along the eastern half. It is surrounded by an outer rampart of ejecta, most notably towards the north, and is at the center of a small ray system. Due to its rays, Harpalus is mapped as part of the Copernican System.The geologic history of the Moon, 1987, Wilhelms, Don E.; with sections by McCauley, John F.; Trask, Newell J. USGS Professional Paper: 1348. Plate 11: Copernican Systemonline The inner surface is terraced, and flows down to the floor. The interior wall is the least wide along the northern face, making the floor slightly offset in that direction. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Condamine (crater)
La Condamine is a small lunar impact crater that is located on the southern edge of the Mare Frigoris, in the northern part of the Moon. It lies to the northeast of the mountain-rimmed Sinus Iridum formation in the northwest part of the Mare Imbrium. The crater rim is low and rounded, with the edge worn and eroded along the northeast side. The outer wall is somewhat polygonal, particularly in the southwestern half. The interior is fairly flat with no central peak, but there is a low curved, double rille in the western half that reaches toward the northern rim. La Condamine is a crater of Lower (Early) Imbrian age. USGS
